Scores on an english test are normally distributed with a mean of 31.5 and a standard deviation of 7.3. find the score that sepa
kobusy [5.1K]

Let X be the score on an english test which is normally distributed with mean of 31.5 and standard deviation of 7.3

μ = 31.5 and σ =7.3

Here we have to find score that separates the top 59% from the bottom 41%

So basically we have to find here x value such that area above it is 59% and below it is 49%

This is same as finding z score such that probability below z score is 0.49 and above probability is 0.59

P(Z < z) = 0.49

Using excel function to find the z score for probability 0.49 we get

z = NORM.S.INV(0.49)

z = -0.025

It means for z score -0.025 area below it is 41% and above it is 59%

Now we will convert this z score into x value using given mean and standard deviation

x = (z* standard deviation) + mean

x = (-0.025 * 7.3) + 31.5

x = 31.6825 ~ 31.68

The score that separates the top 59% from the bottom 41% is 31.68

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table? Drag and drop the values into the
quester [9]

Answer:

.25             .75

.44            .56

Step-by-step explanation:

To find the relative frequency, we take the part over the total.

Since this  is a relative frequency table, the total for each row is 1

Group 1 A  = 15/ (15+45) = 15/60 = .25

Group 1 B = 45/(15+45) = 45/60 = .75

Group 2 A = 20 /(20+25) = 20/45 =.44

Group 2B = 25/(20+25) = 25/45 =.56

A cab driver is paid $6 plus $0. 45 per mile driven. Which expression shows the amount of money the cab driver earns in m miles?
Leni [432]

Algebraic expression is the expression which consist the variables, coefficients and the constants. The expression for the condition given in the problem is 0.45m+6.

Given information

A cab driver is paid $6 plus $0.45 per mile driven.

Total number of total miles is <em>m.</em>

<h3>Algebraic expression</h3>

Algebraic expression is the expression which consist the variables, coefficients and the constants. The algebraic expression are used to solve the condition based problems by expressing them into the algebraic form.

As the cab driver is paid $6 as the fixed amount of the taxi irrespective to the mile driven. Thus this is independent to the other variables and written as the constant in the expression.

As the total miles driven by the cab driver is<em> m</em>. The cost of the per mile driven the car is $0.45. Thus the expression for this condition can be given as,

f(m)=0.45m+6

Hence, the expression for the condition given in the problem is 0.45m+6.
