2.375 number of standard deviation from mean outing with 74 assists.

Data dispersion in regard to the mean is quantified by a standard deviation, or "σ"

By figuring out how far off from the mean each data point is, the standard deviation may be determined as the square root of variance.

The deviation within the data set is bigger when the data points are more away from the mean.

According to the question,

Mean of the number of assists per match is 55

Standard deviation of the same is 8

Let x be the number of standard deviation from mean outing with 74 assists

=> 55 + 8x = 74

Solving for x

=> 8x = 74 - 55

=> 8x = 19

=> x = 19 / 8

=> x = 2.375

Hence, 2.375 number of standard deviation from mean outing with 74 assists.

Answer: 3x + 5

Step-by-step explanation:

First, we need to understand that x is a variable, an unknown number. Think back to how you would do multiplication with numbers that you know. Here are some examples:

If you want to multiply 2 by 3, you would write 3 × 2.

If you want to multiply 3 by 256, you would write 3 × 256.

If you want to multiply 3 by x, you would write 3 × x.

If you want, you can simplify 3 × x to 3x. 3x just means that you are multiplying three by x.

Now we have finished the first step. 3x means three times a number. Now, what about the plus 5?

For the next part, we need to add five to this expression. Think back to how you know how to do addition.

If you want to add 5 to 9, you would write 9 + 5.

If you want to add 5 to 24, you would write 24 + 5.

If you want to add 5 to x, you would write x + 5

If you want to add 5 to 3x, you would write 3x + 5.

In conclusion, 3x + 5 means three times a number (x) plus five. If this doesn't make sense yet, don't worry. You have got this. Don't give up. For more information, search "How to write an expression."

The change in percentage of y when x increases by 5% will be 25%

Direct proportion is a mathematical comparison between two numbers where the ratio of the two numbers is equal to a constant value.

Given that, y is directly proportional to the square of x. we need to find the percentage increase when x is increased by 5%

Since, Y varies directly as the square of x.

Therefore, the general equation to show the direct variation :-

Y = kx²

Let the value of x be 25

25 will be x as 100%. therefore when x is 100%  the value of y will be

Y = 25²k

= 625k

Increasing the value of x by 5%,  

(105x25)/100 = 26.25

Therefore, 105% of 25 = 26.25.

Applying the variation equation, we obtain

Y = (26.25)²k

= 689.0625k

We will find the percentage change in y caused by an increase of x by 5%

(689.0625x100)/625 = 110.25%

Therefore, to find the percentage change in y when x increases by 5% will be,

(110.25-100)% =10.25%

Hence, the change in percentage of y when x increases by 5% will be 25%

The PV factor formula is given below: The formula for PV factor is: PV Factor = [1 - (1 + r)⁻ⁿ] / r

where r = discount rate, and n = number of periods.

PV factor can be used to calculate the present value of an annuity. If the amount of each payment and the number of periods are known, the present value of the annuity can be calculated using the following formula:

Present value of annuity = Payment × PV factor.

For example, suppose that you have an annuity that pays $1,000 per year for 5 years.

The discount rate is 8%. We can calculate the PV factor using the formula:

PV factor = [1 - (1 + r)⁻ⁿ] / r= [1 - (1 + 0.08)⁻⁵] / 0.08= 3.9936

The present value of the annuity can be calculated by multiplying the payment by the PV factor:

Present value of annuity = Payment × PV factor= $1,000 × 3.9936= $3,993.6

Therefore, the present value of the annuity is $3,993.6.

Answer:

Step-by-step explanation:

Let L be the length of this rectangle

The length of a rectangle is 2 feet less than four times the width

● L+2 = 4w

The area of this rectangle is 38.2 ft^2

● L*w = 38.2

The system of equations is

L+2 = 4w => L-4w =2

L*w = 38.2 => L= 38.2/w

Replace L by 38.2/w in L-4w =2

● L-4w = 2

● (38.2/w)-4w = 2

●(38,2-4w^2)/w = 2

● 38.2-4w^2 = 2w

● 38.2-4w^2-2w = 0

● -4w^2-2w+38.2 =0

Multiply by -1 to reduce the - signs

● 4w^2+2w-38.2 =0

This is a quadratic equation so we will use the discriminant

□□□□□□□□□□□□□□□□□

The discriminant is b^2-4ac

● b= 2 (2w)

● a= 4 (4w^2)

● c= -38.2 (the constant term)

b^2-4ac =2^2-4*4*(-38.2) = 615.2 > 0

The discriminant is positive so we have two solutions w and w' :

●●●●●●●●●●●●●●●●●●●●●●●●

w= (-2-24.8)/8 = -3.35

24.8 is the root square of 615.2(the discriminant)

●w is negative

● a distance is always positive so this value isn't a solution

w'= (-2+24.8)/8 =2.85 > 0

So this value is a solution for our equation

■■■■■■■■■■■■■■■■■■■■■■■■■■

w= 2.85 feet

Answer:

w=3.35

Step-by-step explanation:

The length of a rectangle is two feet less than four times the width:

length=4W-2

A=L*W

A=(4W-2)(W)

38.2=4W^2-2W

4W^2-2W-38.2=0  complete the square to find the solution add term(b/2)²

4W²-2W+1/4=38.2+1/4

4(W²-W/2+1/16)=38.45

4(w-1/4)^2=38.45

(w-1/4)²=38.45/4=9.6125

w-1/4=+ or -√9.6125 ( since it is width it has to be positive

w=√9.6125+1/4 = 3.35

The height of the pyramid is 16 feet.

What is Pythagoras Theorem?

Pythagoras' theorem is a fundamental principle in geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

We can use the Pythagorean theorem to find the height of the pyramid.

The slant height of the pyramid is the hypotenuse of a right triangle whose legs are the height of the pyramid and half the length of the base of the pyramid. Since the base is a square, half the length of the base is 12 feet.

Using the Pythagorean theorem:

height² + 12² = 20²

height² = 20² - 12²

height² = 256

height = 16 feet

Therefore, the height of the pyramid is 16 feet.

The probability that three out of the five employees chosen will be women is approximately 0.36

The probability of three out of five randomly chosen employees being women, we can use the concept of combinations.

The total number of ways to choose five employees out of the 16 is given by the combination formula:

C(16, 5) = 16! / (5! × (16-5)!)

= 4368

Now, we need to calculate the number of ways to choose three women from the 8 available, multiplied by the number of ways to choose two men from the remaining 8 employees:

C(8, 3) × C(8, 2) = (8! / (3! × (8-3)!) × (8! / (2! × (8-2)!))

= 56 × 28

= 1568

Therefore, the probability of choosing three women and two men is:

P(3 women and 2 men) = 1568 / 4368 ≈ 0.359

So, the probability that three out of the five employees chosen will be women is approximately 0.36.

AB= 12                      AB=18

Step-by-step explanation:

sin(30)=AB/AC

=> AB=Sin(30)*AC

sin(30)=0.5

=>AB=0.5*24=15

sin(30)=AB/AC

=> AB=Sin(30)*AC

sin(30)=0.5

=>AB=0.5*36=18

Answer:

part a: AB = 12cm

part b: AB = 18cm

Step-by-step explanation:

sin(angle)=OPP/HYP

sine of an angle is a ratio of two sides of a right triangle. For sine, the ratio is the opposite side over the hypotenuse. In part a the marked angle is 30° and AB is the opposite side. The hypotenuse is given, 24cm.

So the sin 30°

= opp/hyp

= AB / 24

also given is the fact that sin30°=.5

Substitute that into our equation also.

sin30° = AB/24

.5 = AB/24

multiply both sides by 24.

.5×24 = AB

12 = AB

AB is 12 cm.

Part b is an identical calculation except the hypotenuse is 36cm.

sin30° = AB/36

.5 = AB/36

.5×36 = AB

18 = AB

AB is 18cm.

Step-by-step explanation:

The sum of the first n terms, Sn of the series is given by; Sn = (2n - 1)a1. The formula is true for all positive integers n. The series diverges and doesn't converge to 1.

(a) Formula for Sn (the sum of the first n terms):The sum of the first n terms, Sn of the series is given by; Sn = (2n - 1)a1

(b) Proving the formula is true by induction:

It can be observed that the formula is true for n = 1. For n = 1, the sum is given by:S1 = a1 = (2.1 - 1)a1 = a1

Let us assume the formula is true for n = k; that is, Sk = (2k - 1)a1

Now we need to prove that the formula is also true for n = k + 1. Therefore, S(k+1) = S(k) + a2k+1

Substituting for S(k) in the above equation, we get; S(k+1) = (2k - 1)a1 + a2k+1

Simplifying the above equation, we have; S(k+1) = (2k + 1)a1

Since the formula is true for n = 1, and it is also true for n = k + 1, then it is true for all positive integers n.

(c) Proving the series converge to 1:

We know that for a series to converge, the limit of the terms of the sequence should approach zero. Thus, let a_n = a1(2n - 1).Then, lim_{n->∞} a_n = lim_{n->∞} a1(2n - 1) = ∞

The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K) and the familiarity with the jokes (denoted by F) using this formula: L = (JK²)/F

Select an appropriate unit for number of laughs:

A) (jokes*knowledge²) / familiarity

B) familiarity / (jokes*knowledge²)

C) familiarity² / (jokes*knowledge)

D) (jokes*knowledge) / familiarity²

Solution

L = f(J, K, F)

where

L = number of laughs

J = number of jokes

K = amount of knowledge about the joke material

F = familiarity with the jokes

Analysing how the dependent variable depends on each of the independent variables.

- Number of jokes

The number of laughs will increase with the number of jokes and vice versa. It can be stated that there is a direct variation between the number of laughs and number of jokes.

- Amount of knowledge about the joke material

The more one understands the joke material, the funnier the joke. In fact, the joke can be termed funnier when one understands the joke material deeply. The direct variation of number of laughs to knowledge about joke material isn't just enough, the number of laughs varying directly as the square of the knowledge of joke material seems more fitting.

- Familiarity with the joke

The more familiar one is with a joke, the less funny it is. Hence, it's an inverse relationship between number of laughs and the familiarity with the joke.

L = (JK²)/F

So, as the formula appears, the appropriate units will be

(jokes*knowledge²) / familiarity

The solution to the equation is x = -2/3.

To solve the equation:

(2/3) - 4x + (7/2) = -9x + (5/6)

We can simplify it by combining like terms:

-4x + (7/2) = -9x + (5/6) - (2/3)

To eliminate the fractions, we can multiply every term by 6 to get rid of the denominators:

6 * (-4x) + 6 * (7/2) = 6 * (-9x) + 6 * (5/6) - 6 * (2/3)

Simplifying further:

-24x + 21 = -54x + 5 - 4

Combining like terms:

-24x + 21 = -54x + 1

To isolate the variable x, we can bring all terms containing x to one side and the constant terms to the other side:

-24x + 54x = 1 - 21

30x = -20

Answer:

x = 11

z = 86

Step-by-step explanation:

8x + 6 and 10x-16 are vertical angles

Vertical angles are pairs of angles that are opposite each other and have the same vertex, or point of intersection. They are formed when two lines intersect at a point, and are always congruent, or of equal measure.

To solve this equation, we need to isolate the variable x on one side of the equation. To do this, we can start by subtracting 6 from both sides of the equation:

8x + 6 - 6 = 10x - 16 - 6

8x = 10x - 22

Now we can subtract 8x from both sides of the equation:

8x - 8x = 10x - 22 - 8x

0 = 2x - 22

To solve for x, we can add 22 to both sides of the equation:

0 + 22 = 2x - 22 + 22

22 = 2x

Finally, we can divide both sides of the equation by 2 to find the value of x: 22 / 2 = 2x / 2

x = 11

Therefore, the solution to the equation is x = 11.

Now that we have x, z is a supplementary angle to 8x + 6 (or you could do 10x - 16)

Supplementary angles are pairs of angles that add up to 180 degrees. They are formed when two lines intersect at a point, and the angles formed at the intersection are supplementary.

First plug in x, 8x + 6 = 8(11) + 6 = 88 + 6 = 94

180 - 94 = z

z = 86

The pass rate in the afternoon subgroup is greater than 1, we cannot draw a reliable conclusion without further investigation or clarification of the data.

To compare the probability that a student will pass the challenge in the morning with the probability that a student will pass the challenge in the afternoon, we need to calculate the proportion of students who passed in each subgroup.

The proportion of students who passed the challenge in the morning subgroup is:

Pass rate in the morning subgroup = Number of students who passed in the morning subgroup / Total number of students in the morning subgroup

Pass rate in the morning subgroup = 40 / 60

Pass rate in the morning subgroup = 0.67

The proportion of students who passed the challenge in the afternoon subgroup is:

Pass rate in the afternoon subgroup = Number of students who passed in the afternoon subgroup / Total number of students in the afternoon subgroup

Pass rate in the afternoon subgroup = 50 / 40

Pass rate in the afternoon subgroup = 1.25

that the pass rate in the afternoon subgroup is greater than 1, which is not possible as probabilities must be between 0 and 1. This implies that there might be a data error.

Assuming the data is correct, we can conclude that the probability of passing the challenge in the afternoon subgroup is higher than the probability of passing the challenge in the morning subgroup. However, since the pass rate in the afternoon subgroup is greater than 1, we cannot draw a reliable conclusion without further investigation or clarification of the data.
