A=18 !!! i hope this helps!
Step-by-step explanation:
20% / 100
0.20 * 44.78
8.9 is 20% of 44.78
Answer:
The measure of angle x is 74°
Step-by-step explanation:
we know that
The inscribed angle measures half of the arc that comprises
so
∠ABC=(1/2)[arc ADC]
substitute the given values
150°=(1/2)[4x+4]
300°=[4x+4]
4x=300-4
4x=296
x=74°
We can find the probability of running length 13 feet by using normal distribution
We first need to find the z-score which is given by applying the following formula:
z-score = (X-μ) ÷ σ
Where:
μ is the average
σ is the standard deviation
X is the sampled value
z-score = (13-14.8) ÷ 2.4
z-score = -0.75
finding the probability, or the p-value by looking up on the z-table
P(Z<z) = P(Z<-0.75) = 0.2266
The conclusion that the biologist could make is that out of 1000 virtual rat, there are 0.2266×1000 = 226.6 ≈ 227 virtual rats that run the maze with length of 13 feet
65.80/4 = 16.45
If she withdrew equal amounts each day, she would have had to withdrawn $16.45 each day.
