Answer:

  (c)  76.3 in^2

Step-by-step explanation:

From the offered selections, you can make an informed choice with a simple estimate.

The overall length of the figure is 8+6 = 14 inches, and its width is 6 inches. The area will be smaller than a 14 × 6 = 84 square inch rectangle, and larger than the central rectangle of 8 × 6 = 48 square inches.

The only choice in the range 48 to 84 square inches is the correct one:

  76.3 square inches

__

If you'd like to figure it out, the area is the sum of the 48 square inch central rectangle and the (π/4)(36 in^2) ≈ 28.26 square inch circle. That total, rounded to tenths, is 76.3 square inches.

Answer:

\(8 {x}^{2} - 6x - 5 = x\)

\(8 {x}^{2} - 7x - 5 = 0\)

x = (7 + √((-7)^2 - 4(8)(-5)))/(2×8)

= (7 + √(49 + 160))/16

= (7 + √209)/16

= -.4661, 1.3411 (to 4 decimal places)

The appropriate hypotheses for this test are: H0: There is no difference in the distribution of responses. Ha: There is a difference in the distribution of responses.

The chosen hypotheses are based on the objective of the investigation, which is to determine if there is convincing evidence that the distribution of responses about eating the potato salad differs between employees who are sick and those who are not sick.

The null hypothesis (H0) assumes that there is no difference in the distribution of responses about eating the potato salad between the sick and non-sick employees. This means that the proportion of employees who ate the potato salad would be the same in both groups, and any observed difference in the distribution of responses is due to random chance or factors unrelated to being sick or not sick.

On the other hand, the alternative hypothesis (Ha) proposes that there is a difference in the distribution of responses about eating the potato salad between the sick and non-sick employees. This suggests that the proportion of employees who ate the potato salad would be significantly different in the two groups, indicating a possible association between consuming the potato salad and getting sick.

By formulating these hypotheses, the investigation aims to evaluate whether the data provides convincing evidence to reject the null hypothesis in favor of the alternative hypothesis, indicating a meaningful relationship between eating the potato salad and falling sick.

Therefore, the correct answer is:

H0: There is no difference in the distribution of responses about eating the potato salad among those who are and are not sick.

Ha: There is a difference in the distribution of responses about eating the potato salad among those who are and are not sick.

Answer:

Add all the digits of the number, then check if that sum is divisible by 9. If yes, we know the number is divisible by 9.

Answer:

I believe the equation is $50 + $15m = $275

Step-by-step explanation:

Since you're writing an equation, there must be an equal sign involved. (An expression does not have an equal sign)

Let's start:

We know that you have to pay $50 as a starting fee and it costs an additional $15 PER month. The problem tells you that the variable "m" represents the number of months you spend as a member...thus:

$50 + $15m

and since the total cost for the gym was $275...

Your answer should be $50 +15m = $275

Answer:

100°

Step-by-step explanation:

tThe sum of all arc measures that make up that circle is 360 degrees.

QS + RQ + RS = 360

QS = 360 - 120 - 140 = 100

An arc angle is the degree measurement of that angle inside the circle, opposite the arc

m∠R = arc QS = 100°

Answer:

∠ R = 50°

Step-by-step explanation:

the inscribed angle R is half the measure of its intercepted arc QS

the sum of the arcs on a circle is 360° , that is

RQ + QS + SR = 360°

120° + QS + 140° = 360°

QS + 260° = 360° ( subtract 260° from both sides )

QS = 100°

Then

∠ R = \(\frac{1}{2}\) × 100° = 50°

Given,

Total no. of cards = 52

No. of 2 of spades cards = 1

Therefore,

Probability of getting 2 of spades

\( = \frac{no. \: of \: required \: outcomes}{total \: outcomes} \)

\( = \frac{1}{52} (ans)\)

Answer:

Step-by-step explanation:

step 1

100%/the total number = percent for one probability

100/5 = 20%

2 and 4 is even.

total even number * percent for one probability = total percent for even number

20% * 2 = 40%

therefore total even number is 40%

The probability is:

Step-by-step explanation:

Remember the formula for probability:

\(\boxed{\!\!\boxed{\bold{Probability=\frac{Favourable~outcome}{total~outcomes}\quad}}\!\!}\)

In this case, the favourable outcome (an even number) is 2, because there are only 2 even numbers in the set.

As for the total outcomes, there are 5 of them, because we have 5 numbers total.

So the probability of choosing an even number is 2/5.

Saha current position is 696.58m from his starting position.

Data;

To solve this question, we can use sine or cosine rule.

But since his current position is North of his starting point, we can use sine rule here

\(\frac{a}{sinA} = \frac{b}{sin B}\\\)

where b represents the distance from his current position to his starting position.

\(\frac{a}{sinA} = \frac{b}{sin B} \\\frac{600}{sin53} = \frac{b}{sin 68} \\\)

Let's cross multiply and solve b

\(b= \frac{600sin68}{sin53} \\b = 696.58m\)

Step-by-step explanation:

Three-fifths times a number is 15.

Raphael needs to run 3.9 miles on Friday so that he will have a total of 11 1/2 miles for the week.

What is Subtraction ?

An arithmetic operation called subtraction simulates the process of deleting items from a collection. The negative symbol, or, denotes subtraction.

Raphael ran a total of 7 3/5 miles through Monday to Thursday.

We'll convert it from mixed fraction to simple fraction :

7 3/5 miles = [(7×5) + 3] / 5

                   = 38/5 miles.

He wants to have a total of 11 1/2 miles for the week.

Again, we will convert it into simple fraction :

11 1/2 miles = [(11×2) + 1 ] / 2

                  = 23/2 miles.

Let's he needs to run x miles to a total of 23/2 miles.

So, x + 38/5 = 23/2

     x = 23/2 - 38/5

        = [(23×5) - (38×2)] / 10

        =  (115 - 76)/10

        = 39/10 miles = 3.9 miles.

Step-by-step explanation:

The unknown angles of the kites are as follows:
m∠1 = 90°

m∠2 = 65°

m∠3 = 90

m∠4 = 65°

m∠5 = 25°

A kite is a quadrilateral that has 90° angles at the point of intersection of the two diagonals. The sum of angles in a kite is 360 degrees.

Therefore, the diagonal of a kite bisect each other at right angle.

Diagonals also bisect each angles.

Using the diagonal theorem of the kite,

m∠1 = 90 degrees

m∠2 = 180 - 25 - 90 = 65 degrees(sum of angles in a triangle)

m∠3 = 90 degrees

m∠4 = 65 degrees(Base angles of an isosceles triangles are congruent)

m∠5 = 25 degrees

Answer:

sin (E) = 8/17

An equation for the total cars and trucks for dealership A is: x + y = 164.

An equation for the total cars and trucks for dealership B is: 2x + 0.5y = 229.

The number of cars that dealership A sold is: 98 cars.

The number of trucks that dealership B sold is: 66 trucks.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of cars sold and number of trucks sold, and then translate the word problem into an algebraic equation as follows:

Since the first dealership sold a total of 164 cars and trucks, a linear equation to model this situation is given by;

x + y = 164.

Additionally, the second dealership sold twice as many cars and half as many trucks as the first dealership, with a total of 229 cars and trucks;

2x + 0.5y = 229.

By solving the systems of linear equations simultaneously, we have:

2x + 0.5(164 - x) = 229

1.5x + 82 = 229

x = 98 cars.

For the y-value, we have;

2(98) + 0.5y = 229

0.5y = 229 - 196

y = 33/0.5

y = 66 trucks.

Comparing the obtained result with the general form of the equation:

y = mx + c

Where m = gradient or slope whose value gives the variation in cost per rental return (x)

c = intercept, which is constant or fixed, it is the value where the regression line crosses the y axis, hence, it corresponds to the fixed cost.

Hence,
