Answer: Choice A
The coordinates of triangle ABC have been multiplied by a scale factor of 0.5
In other words, the coordinates have been cut in half or they divided each coordinate value over 2
eg: (-3,4) --> (-1.5, 2)
since -3/2 = -1.5 and 4/2 = 2
The resulting figure is smaller. Specifically the linear dimensions are half that as the original.
Answer:
The probability is 0.9909.
Step-by-step explanation:
Test statistic (z) = (sample mean - population mean) ÷ (sd/√n)
sample mean = 290 days
population mean = 298 days
sd = 22 days
n = 42
z = (290 - 298) ÷ (22/√42) = -8 ÷ 3.395 = -2.36
The cumulative area of the test statistic is the probability that the mean gestation period is less than 290 days. The cumulative area is 0.9909. Therefore the probability is 0.9909.
