Step-by-step explanation:
Given that,
∠PSQ = 13x+7
∠QSR = 42x+8
We need to find the measure of angles.
We can use the property of linear pair. ATQ,
13x+7 + 42x+8 = 180 (Linear pair)
Taking like terms,
13x+42x = 180 - 7-8
55x = 165
x = 3
So,
∠PSQ = 13x+7 = 13(3) + 7 = 46°
∠QSR = 42x+8 = 42(3) + 8 = 134°
Hence, this is the required solution.
Critical values are basically cut-off values that indicate regions where the test statistic is unlikely to lie. The required critical value is 1.31.

What are critical Values?</h3>
Critical values are basically cut-off values that indicate regions where the test statistic is unlikely to lie; for example, if the null hypothesis is true, the critical value is surpassed with probability alpha.
The value of α can be written as,
α = 1 - 0.81 = 0.19
Now, using the z-table the value of z will be,
z = 1.31
Hence, the required critical value is 1.31.

Answer: Mrs, William takes 18 treats to school.
Step-by-step explanation:
Given: When the crispy treats have cooled Mrs. Williams cut theme into 30 equal pieces .
She give 2/5 to her son, then the number of treats ahe give to her son = 
Then, the number of treats Mrs. Williams take to school =
Hence, Mrs, William takes 18 treats to school.

Step-by-step explanation:
Answer:
245 in^2.
Step-by-step explanation:
The net consists of 1 square and 4 triangles.
Surface area = 7^2 + 4 * 1/2 * 7 * 14
= 49 + 196
= 245 in^2.
