Alternate interior angles are:
(2x-70) = (x+30)
2x-x = 30+70
x = 100

the angle 5y is supplementary to the other angle.
5y + (100+30) = 180
5y + 130 = 180
5y = 180-130
5y = 50
y = 50/5
y = 10

How many women must be randomly selected to estimate the mean weight of women in one age group. We want 90% confidence that the

Pie

Answer: the required sample size = 155

Step-by-step explanation:

If the standard deviation of the prior study is known, then the formula to compute required sample size:

$n=(\frac{z^*\times\sigma}{E})^2$ , where E = Margin of error, z* = Critical value, $\sigma$ = populion standard deviation.

Given: E = 3.7 , $\sigma=28$

Critical value for 90% confidence = 1.645

Required sample size: $n=(\frac{1.645\times28}{3.7})^2$

$n=(12.4486486486)^2\approx155$

Hence, the required sample size = 155

JulijaS [17]

Answer: The loan have been $2500 originally.

Step-by-step explanation:

Since we have given that

Interest = $750

Rate of interest = 3%

Number of year = 1

Let P be the principal amount .

So, According to question, we get that

$750=\dfrac{P\times R\times T}{100}\\\\750=\dfrac{P\times 3\times 1}{100}\\\\\dfrac{750\times 100}{3}=P\\\\$2500=P$

Hence, the loan have been $2500 originally.
