If IQ Scores are normally distributed with a mean of 100 and a standard deviation of 15. If you randomly selected a person
from Montana, what is the probability, rounded to the hundredth, that a person will have an IQ less than 79?
Remember to use the percent sign in this question

The total number of winning hands are 276.

Probability is defined as the ratio of favorable outcomes to all other possible outcomes of an event. The symbol x can be used to express the quantity of successful outcomes for an experiment with 'n' outcomes. The probability of an event can be calculated using the following formula.

Probability of an event = Number of favourable outcomes/Total number of outcomes = x/n.

In the given question,

If the first card drawn is a 10, then there are

\(P_9^2=\frac{9!}{(9-2)!} =9*8=72 hands\)

There are 9 possible numbers if the second card is a 10, and there are 8 possible numbers if the third card, giving us,

\(9*8= 72 hands\)

If the third card is 10 then there are 9 possible numbers for the first card and 8 possible numbers for

second card, it gives us

\(9*8= 72 hands\)

And there are 5 odd cards, and it gives us:

\(P_5^3=\frac{5!}{(5-3)!} =5*4*3=60 hands\)

So, we have that in total we have

72+72+72+60=276 winning hands.

Answer:

Step-by-step explanation:

i am working on the assumption that nobody does all three of them

i got 4 because including the people that do swimming and park, the total number of people that do swimming is 22.

the same logic goes for cycling: including the people that do swimming and visit the national park, the total is 23.

so that means that find how many people do swimming and cycling, we have to add the people doing only swimming, with the people doing both swimming and park and then subtract that answer from 22 which gives you 4

The correct answer is U - II = I + III + IV.

In order to solve problems based on these sets, we can use a Venn diagram to depict the logical relationship between sets and their components. Although other closed figures like squares may be used, a Venn diagram commonly uses intersecting and non-intersecting circles to indicate the relationship between sets.

c represent the compliment of the particular state.

U is the union set

∩ represent intersection between the neighbouring sets

Therefore,

Bc = U - B = I + II

Bc∩A = Area common in Bc and A = II

(Bc∩A)c = Area in U but not in (Bc∩A) = U - II = I + III + IV

So, answer is d.

The probability that Betty is first in line or Mary is last in line as a function of n is  \(\frac{2n - 3}{n(n-1)}\).

It is given that number of kids are 'n' in the line including Betty and Mary. The total number of ways in which the kids can line up is "n!"

Let A denote that Betty is in the first place and B denotes that Marry is in the last place in the line.

Now, Betty can be at first place in (n-1)! ways

Therefore, P(A) = \(\frac{(n-1)!}{n!}\)

And Mary can be at last in the line in (n-1)! ways

Therefore, P(B) = \(\frac{(n-1)!}{n!}\)

Betty is first in the line and Mary is last in the line in  (n-2)! ways

so P(A∩B) = \(\frac{ (n-2)! }{ n! }\)

The probability that Betty is first in line or Mary is last in line can be calculated by

P(A ∪ B) = P(A) + P(B) - P(A∩B)

P(A ∪ B) =  \(\frac{(n-1)!}{n!}\) +  \(\frac{(n-1)!}{n!}\) - \(\frac{ (n-2)! }{ n! }\)

P(A ∪ B) = \(\frac{1}{n} + \frac{1}{n} -\frac{1}{n(n-1)} =\frac{2n -3}{n(n-1)}\)

The statement that the one with a higher coefficient of variation exhibits higher variability is true.

The coefficient of variation expresses the proportionate level of variability present in a random variable and can be determined by dividing the mean by the standard deviation.

If the coefficient of variation is higher, it means that the random variable shows more variation in relation to its mean.

To illustrate, suppose that the average height of a set of males is 6 feet with a standard deviation of 2 inches.

The variance ratio would result in a coefficient of variation of 0. 033 Suppose that a group of females has an average height of 5 feet with a standard deviation of 1 inch.

The women's coefficient of variation is calculated to be 0. 02 The variance of men's height in relation to their average height is indicated by their higher coefficient of variation.

Based on the coldest temperature in Buffalo and the difference in the temperature of Chicago, the equation that can be used to find the coldest temperature in Chicago is C. C - 12 = -39; -27°

When temperatures are warmer, it means that they are higher. This means that to find the coldest temperature in Chicago, you need to add 12°F to the temperature of Buffalo.

The formula would therefore be:

C = -39 + 12

Making the Buffalo temperature the subject gives;

C - 12 = -39

The coldest temperature in Chicago is:

= -39 + 12

= -27°F

Answer:

Distributivity.

Step-by-step explanation:

The function for position x(t) could be x(t) = 3t^2 - 2t + 10.

In mathematics, a function is a relation between two sets that assigns to each element of the first set exactly one element of the second set. In other words, it is a rule that describes how one set of values is related to another set of values. Functions are used to model real-world scenarios and to solve mathematical problems. Examples of functions include linear equations, polynomials, and trigonometric functions.

This is determined by using the equation x'(t) = a(t). Differentiating both sides of the equation, we get x'(t) = 6t - 2. Integrating this equation, we get x(t) = 3t^2 - 2t + C, where C is the constant of integration. Since x(1) = 10, we can substitute this value into the equation and solve for the constant of integration. Therefore, we get x(t) = 3t^2 - 2t + 10.

Answer:

m = 2

Step-by-step explanation:

Given:

x = 4

y = 6m - 2

a = 8

b = 5

Required:

Value of m

SOLUTION:

x and y are segments of a chord divided when it intersects another chord that also has segments a and b.

According to the Intersecting chords theorem, \( a*b = x*y \)

Thus:

\( 8*5 = 4*(6m - 2) \)

Solve for m

\( 40 = 24m - 8 \)

\( 40 + 8 = 24m - 8 + 8 \)

\( 48 = 24m \)

\( \frac{48}{24} = \frac{24m}{24} \)

\( 2 = m \)

The value of m = 2

From the question, we have the following parameters that can be used in our computation:

The graph of g(x)

Also, we have

The graph of g(x) is a translation of f(x)=x^2

From the graph, we can see that

Using the above as a guide, we have the following:

g(x) = f(x - 2) + 3

Substitute the known values in the above equation, so, we have the following representation

g(x) = (x - 2)^ + 3

Answer:

The standard deviation of the population is 4.5 minutes.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \(\mu\) and standard deviation of the population \(\sigma\), the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \(\mu\) and standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).

In this question:

\(s = 0.5, n = 81\)

So

\(s = \frac{\sigma}{\sqrt{n}}\)

\(0.5 = \frac{\sigma}{\sqrt{81}}\)

\(\sigma = 9*0.5 = 4.5\)

The standard deviation of the population is 4.5 minutes.

The expressions can be simplified as follows-

1. (9 − 3) 2− (5 • 4)0 = 12

2. (2 + 3)5 ÷ (5 × 2)2 = 5/4

3. 4 × 2 ÷ (6 − 2)4 = 1/2

4. [(1 + 7) 2] 2• (12 2 )0 = 0

Let us look at each expression one by one-

1. (9 − 3) 2− (5 • 4)0

Zero multiplied by any number is 0 itself. Thus, the expression becomes-

= (9 - 3) 2

= 6 × 2

= 12

2. (2 + 3)5 ÷ (5 × 2)2

According to the rules of BODMAS, we first solve the brackets-

(5)5 ÷ (10)2

= 25 ÷ 20

= 25/20

= 5/4

3. 4 × 2 ÷ (6 − 2)4

= 4 × 2 ÷ (4)4

= 8 ÷ (4)4

= 8/16

= 1/2

4. [(1 + 7) 2] 2• (12 2 )0

= [(8)2]2• 0
