Subtitute the pair (3,28) to x and y, if the result in right side is -8, then the pair is a solution to the equation

2x - y/2
= 2(3) - 28/2
= 6 - 14
= -8

The result is -8, so the pair (3,28) is a solution

What is the greatest common factor of 9x^{2}y9x 2 y and 5x^{4}y^{2}5x 4 y 2 ?

Musya8 [376]

ANSWER

The greatest common factor is
${x}^{2} y$

EXPLANATION

We want to find the greatest common factor of

$9 {x}^{2} y$

and

$5 {x}^{4} {y}^{2}$

The prime factorizations are;

$9 {x}^{2} y = {3}^{2} \times {x}^{2} \times y$

and

$5 {x}^{4} {y}^{2} = 5 \times {x}^{4} \times {y}^{2}$

The product of the least powers of the common factors is the greatest common factor.

$= {x}^{2} y$

A trucking firm has a large inventory of spare parts that have been in storage for a long time. It knowsthat some proportion of

Debora [2.8K]

Answer:

$0.1546\leq \widehat{p}\leq 0.3513$

Step-by-step explanation:

The firm tests 75 parts, and finds that 0.25 of them are notusable

n = 75

x = 0.25 \times 75 = 18.75≈19

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{19}{75}$

$\widehat{p}=0.253$

Confidence level = 95%

So, Z_\alpha at 95% = 1.96

Formula of confidence interval of one sample proportion:

$=\widehat{p}-Z_\alpha \sqrt{\frac{\widehat{p}(1-\widehat{p}}{n}}\leq \widehat{p}\leq \widehat{p}+Z_\alpha \sqrt{\frac{\widehat{p}(1-\widehat{p}}{n}}$
