Factor -1/4 out of -1/2x -5/4y. (i will mark brainlyest)
mash [69]

Answer:

-1/4 (2x - 5y)

Step-by-step explanation:

For us to factor -1/4 out of -1/2x -5/4y

We will have to multiply the values in bracket by the reciprocal of -1/4 i.e -4 as shown

-1/2x - 5/4 y

= -1/4 (-4(-1/2x) - (-4)(-5/4y))

= -1/4 (4/2 x - 20/4 y)

= -1/4 (2x - 5y)

Hence the factored expression is -1/4 (2x - 5y)

SpyIntel [72]

Answer: 1308

Step-by-step explanation:

Given : Level of confidence = 0.97

Significance level : \alpha=1-0.97=0.03

Critical value : z_{\alpha/2}=2.17

Margin of error : E=0.03

If prior proportion of population is unknown , then the formula to find the population proportion is given by :-

n=0.25(\dfrac{z_{\alpha/2}}{E})^2

\Rightarrow n=0.25(\dfrac{2.17}{0.03})^2=1308.02777778\approx1308

Hence, the minimum sample size needed =1308
