P ( A and B ) = 0.051.
P ( B ) = 0.32
According to Bayes` rule:
P ( A\B ) = P ( A and B ) /P ( B ) = 0.051/ 0.32 = 0.159375 ≈ 0.159
Answer: B ) 0.159

Find the value of y in parallelogram QRST.

Arturiano [62]

<h2>Answer:</h2>

y = 5

<h2>Step-by-step explanation:</h2>

<em>Solution:</em>

7y = 5y + 10

7y - 5y = 10

2y = 10

$\frac{2y}{2}$ = $\frac{10}{2}$

y = 5

<em>Checking:</em>

7y - 5y = 10

7(5) - 5(5) = 10

35 - 25 = 10 ✓

A population mean of 360, a standard deviation of 4, and a margin of error of 2.5%

Ad libitum [116K]

Answer:

(351.04, 368.96)

Step-by-step explanation:

Given that population mean= 360

Std devitaion = 4

margin of error = 2.5%= 0.025

Since population std deviation is known we can use Z critical value

For two tailed critical value for 2.5% would be

2.24

Margin of error = ±Critical value*std deviation

= ±2.24(4)

= ±8.96

Confidence interval =(Mean - margin of error, mean + margin of error)

= $(360-8.96, 360+8,.96)\\= (351.04, 368.96)$
