Answer:
∠1 = 66°
∠2 = 24°
∠3 = 24°
∠4 = 90°
Step-by-step explanation:
∠1 = 90 - 24 = 66°
∠2 = 24°
∠3 = 24° because segment DB bisects ∠ABC
∠4 = 90° because it is a right angle
Answer: ($143.69, $156.31)
Step-by-step explanation:
Confidence interval to estimate population mean :

, where
= population standard deviation
n= sample size
Sample mean
z= critical value.
As per given,
n= 40
= $15.50
$150
Critical value for 99% confidence level = 2.576
Then, 99% confidence interval for the population mean:

Hence, the required confidence interval : ($143.69, $156.31)
Answer:
99
Step-by-step explanation:
Given the linear equation:
y = 0.6x + 45
x = outdoor temping degrees ; y = number of pair of sandal sold
Number of pairs of sandals the company expect to sell if the outside temperature is 90 degrees?
y = 0.6(90) + 45
y = 54 + 45
y = 99
The expected number of sandals to sale will be 99
The answer is 12.
To double check mulitply 12 times 0.29 = 3.480
That is how we know 12 is the correct answer.
