Answer:

m∠PQR = 133

Step-by-step explanation:

∠PQR and ∠RQS are supplementary angles, meaning they have a sum of 180°.

3x - 5 + x + 1 = 180

4x - 4 = 180

4x = 184

x = 46

Now we simply substitute 46 in for x:

3(46) - 5 = 133

Answer: 0.418 < p < 0.512

Step-by-step explanation: A 95% conifdence interval for a population proportion is given by:

$p + z\sqrt{\frac{p(1-p)}{n} }$

where:

p is the proportion

z is score in z-table

n is sample size

The proportion for people who said "yes" is

$p=\frac{202}{434}$ = 0.465

For a 95% confidence interval, z = 1.96.

Calculating

$0.465 + 1.96*\sqrt{\frac{0.465(0.535)}{434} }$

$0.465 + 1.96*\sqrt{0.00057}$

0.465 ± 1.96*0.024

0.465 ± 0.047

Interval is between:

0.465 - 0.047 = 0.418

0.465 + 0.047 = 0.512

<u>The interval with 95% of confidence is between 0.418 and 0.512.</u>

Use the zero property to determine the solutions for (2x + 6)(x - 7) = 0.

Nuetrik [128]

Answer:

x = -3

x = 7

Step-by-step explanation:

If either term is zero the product is zero

(2x + 6)(x - 7) = 0

2x + 6 = 0

2x = -6

x = -3

x - 7 = 0

x = 7
