Write an inequality to represent the phrase: the difference of a number and 9 is no more than 95

Sliva [168]

Answer:

$x-9\leq 95$

Step-by-step explanation:

Let

x ----> the number

we know that

The phrase " the phrase: the difference of a number and 9" is equal to

subtract the number 9 from the number x

(x-9)

The phrase" no more than 95" means "less than or equal to 95" (≤95)

The inequality that represent this situation is

$x-9\leq 95$

Write a linear function f with f(−10)=4 and f(−2)=4. f(x)=

ZanzabumX [31]

Answer:

f(x) = 4

Step-by-step explanation:

Let us assume that the linear function f(x) = ax + b

Here, we have to find the value of a and b to know the function.

Given that f(-10) = 4 and f(-2) = 4

So, -10a + b = 4 ....... (1) and

-2a + b = 4 .......... (2)

From equations (1) and (2) we get a = 0 and b = 4.

So, the linear function is f(x) = 4. (Answer)

You plan to conduct a survey to find what proportion of the workforce has two or more jobs. You decide on the 95% confidence lev

Vikentia [17]

Answer:

865

Step-by-step explanation:

We have that in 95% confidence level the value of z has a value of 1.96. This can be confirmed in the attached image of the normal distribution.

Now we have the following formula:

n = [z / E] ^ 2 * (p * q)

where n is the sample size, which is what we want to calculate, "E" is the error that is 2% or 0.02. "p" is the probability they give us, 5 out of 50, is the same as 1 out of 10, that is 0.1. "q" is the complement of p, that is, 1 - 0.1 = 0.9, that is, the value of q is 0.9.

Replacing these values we are left with:

n = [1.96 / 0.02] ^ 2 * [(0.1) * (0.9)]

n = 864.36

865 by rounding to the largest number.
