40 : 60
2 : 3
Answer: BXC =70°
Step-by-step explanation:
XBC= isosceles so XBC=XCB
XBC=55° (isosceles triangle)
BXC+XBC+XCB=180° (angles in a triangle =180°)
BXC=180°- (55°+55°)
BXC=180°-110°
BXC=70°
Answer:
C
Step-by-step explanation:
Answer: Eric spends $41.44 on the contact paper.
Step-by-step explanation:
The dimensions of the box are 9 inches, 11 inches, 8 inches.

Since, the contact paper costs 8 cents per square inch.
The cost of covering the box=
Since, 1 $ = 100 cents or 1 cent =0.01 dollar.
Therefore, The cost of covering the box=
Answer:
The probability that the mean delivery time from the sample of 25 orders xˉ is farther than 2 minutes from the population mean cannot be calculated.
Step-by-step explanation:
As given in the question statement, the distribution of delivery times is strongly skewed to the right. The population distribution is skewed to right. Too much skewed distribution can cause the statistical model to work ineffectively and affects its performance. The probability can also not be calculated because the sample size is too small. Small sample size affects the results and makes them less reliable because it results in a higher variability and likelihood of skewing the results.
