Intelligence Quotient (IQ) scores are often reported to be normally distributed with μ=100.0 and σ=15.0. A random sample of 59 people is taken. Step 1 of 2 : What is the probability of a random person on the street having an IQ score of less than 98 ? Round your answer to 4 decimal places, if necessary.

Answers

Using the normal distribution, it is found that there is a 0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 100[/tex] and [tex]\sigma = 15[/tex].

The probability of a random person on the street having an IQ score of less than 98 is the p-value of Z when X = 98, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{98 - 100}{15}[/tex]

[tex]Z = -0.13[/tex]

[tex]Z = -0.13[/tex] has a p-value of 0.4483.

0.4483 = 44.83% probability of a random person on the street having an IQ score of less than 98.

What is percentage?

Percentage is defined as ratio expressed as a fraction of 100.

No. of students in college in last year = 123 -27 = 96

The number of students leaving college ratio = (27/96)×100%

Find the area of an equilateral triangle with a side length of 16 centimeters. Round to the nearest tenth.

As we know that the area of an equilateral triangle with side a is given by ;

So , now using formula in our question, putting the value of the side, we can thus obtain

Putting value of √3 ≈ 1.73 and cancelling 4 we have ;

Emilliano thinks x =40 is the solution to the equation 1/2 x =80. explain why he is wrong

Answers

Answer/Step-by-step explanation:

Given:

Emiliano thinks x = 40 is the solution to the equation 1/2x = 80

Note:

An equation is the statement that equalizes two mathematical expressions.

An expression is the combination of variables and constants connected with mathematical operations.

Solve:

Substituting the value of x, in the equation

1/2(4) = 80

    20 ≠ 80

Thus,   it isn't satisfied. Hence, Emiliano's answer is wrong.    

Correct Way to Solve;                

Multiply both sides by 2

2 · [tex]\frac{1}{2}x[/tex] = 80 · 2

Simplify

x = 160

The sum of three consecutive integers is -561. What are the
integers?
I

Answers

Answer:

-188, -187, -186

Step-by-step explanation:

x + (x+1) +(x+2) will usually be the formula for questions like this. If there wer 4 consecutive numbers, you just add (x+3) and so on.

The three integers are:

x + (x+1) + (x+2)   Simplify this :

3x+3 = -561       Get 3x by itself, subtract 3 on both sides:

    -3    -3

3x = -564   Find x divide -564 and 3:

x = -188

-188 is the first number now you count up.

-188 is the first number, -187 is the second, -186 is the third.

A grocery store sells sliced turkey. The graph shows the relationship between the weight of the sliced turkey and the total cost of the sliced turkey. Two points, R and W, are labeled on the graph shown below.

Answers

Answer:

The correct option is ⇒ Point W means that that unit rate is $2.5 per pound.

Step-by-step explanation:

The question missing the graph and the options

The options for the questions are:

1) Point R means that that unit rate is $10 per pound.

2) Point R means that that unit rate is 4 pounds per dollar

3) Point W means that that unit rate is $2.5 per pound.

4) Point W means that that unit rate is 2.5 pounds per dollar.

And see the attached figure.

As shown in the figure attached

The unit rate will be the total cost per weight

By calculating the unit rate for the graph = (y2-y1)/(x2-x1)

using the given points (4,10) , (1,2.5)

the unit rate = (10-2.5)/(4-1) = 7.5/3 = 2.5

The unit rate means that it will cost $2.5 per pound and this is a gree with the point W which have the same meaning.

So, The correct answer is option 3.

Answers

Answer:

2%

Step-by-step explanation:

If 300 minutes is 100%, how much percent is 306 minutes?

we need to use the rule of three

306 minutes x 100% / 300 minutes = 102%

Therefore the percent of the increase is 102%-100%= 2%
