What are the values of a and b

Mathematics
1 answer:
dimulka [17.4K]3 years ago
6 0
Answer:
A= 73 degrees
B= 34 degrees

Explanation:
Through the diagram, it is given that QP is a straight line. By supplementary angles(meaning in straight lines of 180 degrees, the angles must add to 180), angle a plus 107 degrees must equal 180 degrees. So:
a+107=180
a= 73
Next, angles RQP and RPQ are congruent because of the sides are congruent, the angles must be congruent. All angles of a triangle must equal 180 degrees. Given the previous, 2a+b=180. Plug a in and solve for b:
2(73)+b=180
146+b=180
b= 34
In conclusion, A= 73 degrees and B=34

** please check my math as I do not have a calculator with me lol

A random sample of 12 recent college graduates reported an average starting salary of $54,000 with a standard deviation of $6,00
Marianna [84]

Answer: a.) $50188 to $57812

Step-by-step explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values in which we are confident the true mean is in.

The interval is calculated as

x ± z\frac{s}{\sqrt{n} }

a. For a 95% CI, z-value is 1.96.

Solving:

54,000 ± 1.96.\frac{6000}{\sqrt{12} }

54,000 ± 1.96\frac{6000}{3.464}

54,000 ± 1.96*1732.102

54,000 ± 3395

This means the interval is

50605 < μ < 57395

<u>With a 95% confidence interval, the mean starting salary of college graduates is between 50605 and 57395 or </u><u>from 50188 to 57812$.</u>

<u />

b. The mean starting salary for college students in 2017 is $50,516, which is in the confidence interval. Therefore, since we 95% sure the real mean is between 50188 and 57812, there was no significant change since 2017.
