Find the angle measure of PQR
sineoko [7]

Answer:

<em>64 degrees</em>

Step-by-step explanation:

When you have the SRQ angle, you can easily solve for PQR. Luckily, we're given that QRP and PRS are 32 and 84, respectively. Adding this together gives you 116. 116*2 = 232 and 360-232 = 128, and 128/2 = 64.

<em>Please Mark Brainliest if this helps!</em>

The following data represent the pH of rain for a random sample of 12 rain dates. a normal probability plot suggest the data cou
babunello [35]

Answer:

Step-by-step explanation:

a) Estimate for population mean = Sum/n =\frac{59.1}{12} =4.925

b) Variance = 0.099208

Std dev = 0.314974

Std error = 0.0950

For 95% margin of error = 1.96*Std error

=0.1861

Confidence interval = (4.925-0.1861, 4.925+0.1861)\\=(4.7389, 5.1111)

Interpretation of confidence interval:

A) if repeated samoles are taken, 95% of them will have a sample pH of rain water between [ ] & [ ].

For 99%  CI,  z value = 2.59

Conf interval = (4.6790, 5.1710)

C)if repeated samoles are taken, 99% of them will have a sample pH of rain water between [ ] & [ ].

As the level of confidence increases l, the width of the interval[ increases] this makes sense since the [  margin of error] [increases]

From the set {1, 3, 4}, use substitution to determine which value of x makes the equation true.
Harlamova29_29 [7]

-2x = 22 - 30

-2x = -8

(dived both sides by -2)

x= 4
