So decrease is 375-250=75
so convert 75/375 to percent
percent means part out of 100 so
x/100=x%
divide 125/375=0.3333/1
multiply by 100/100=33/100=33%
the answer is 33% or B
Answer:
51 ft
Step-by-step explanation:
y-12 = -1/4 (x-3) = 51 ft
Step-by-step explanation:
a. The point estimate is the mean, 47 days.
b. The margin of error is the critical value times the standard error.
At 31 degrees of freedom and 98% confidence, t = 2.453.
The margin of error is therefore:
MoE = 2.453 × 10.2 / √32
MoE = 4.42
c. The confidence interval is:
CI = 47 ± 4.42
CI = (42.58, 51.42)
d. We can conclude with 98% confidence that the true mean is between 42.58 days and 51.42 days.
e. We can reduce the margin of error by either increasing the sample size, or using a lower confidence level.
Answer:
subtraction property
Step-by-step explanation:
because you subtracted 12x from 16x to get 4x+5=-6
Answer:
x = 43
Step-by-step explanation:
180 - 65 = 115
115 = x + 72
<u>-72 -72 </u>
43 = x
x = 43
