Answer:

The answer is " $\frac{1}{25}$ "

Step-by-step explanation:

They might claim that perhaps the ratio to Raul would've been: $\frac{y}{x} = \frac{5}{125} = \frac{1}{25}$ per each 125(x) page, which he reviewed throughout a summer competition.

Raul's cost per unit for each paragraph reads is $\frac{1}{25}$ page points, that's why the model a link with the same unit rate. please find the graph in the attached file.

kap26 [50]

Answer:

Step-by-step explanation:

The sum of these two polynomials is - 2 x^2 - 3. the two x variables are additive inverses and -6 x^2 and 4 x^2 equal - 2 x^2 and -3 results from -4 and 1

Multiplying the sum by 2 gives us - 4 x^2 - 6 . Answer 3

A fashion designer wants to know how many new dresses women buy each year. Assume a previous study found the standard deviation

horsena [70]

Answer:

649

Step-by-step explanation:

Given that

Mean number of dresses is 5.5

Standard deviation of the sample, S.D is 1.3

Margin of error, M.E is 0.1

Level of confidence is 95% or 0.95

The formula for margin of error, M.E is

Z * (S.D/√n) , where

Z = Value for level of confidence which is 1.96

Proceeding further, we have

0.1 = 1.96 * (1.3/√n)

0.1 = 2.548 / √n, making √n subject of formula, we have

√n = 2.548 / 0.1

√n = 25.48, squaring both sides

n = 25.48²

n = 649.23

Therefore the number of sample size we're looking for is n = 649.23, when rounded to the nearest integer, we have it to be 649
