8 ft wide, 12 ft long......so if u want it 2 ft wide, u have a scale factor of 1/4.
that means ur length will be 12 * 1/4 = 12/4 = 3 ft long
A = L * W
A = 3 * 2
A = 6 square ft <==
Answer:
The indicated confidence interval for the difference between the two population means is (-1.5159, 7.5159)
Step-by-step explanation:
Let the drying times of type A be the first population and the drying times of type B be the second population. Then
We have small sample sizes 
and 
, besides 
, 
, 
and 
. Therefore, the pooled
estimate is given by
The 99% confidence interval for the true mean difference between the mean drying time of type A and the mean drying time of type B is given by
, i.e.,
where 
is the 0.5th quantile of the t distribution with (11+9-2) = 18 degrees of freedom. So
, i.e.,
the indicated confidence interval for the difference between the two population means is (-1.5159, 7.5159)
i just took the quiz and its 32 :)
You split the shape into two rectangles and then find the missing side lengths and then you can find the area of each rectangle and add them up. i did a vertical line on the left side of the extra piece so then you would have two rectangles rectangle 1= 5x5 and rectangle 2= 2x6. then you find the area of each- 5x5=25 and 2x6=12. 25+12= 37 so the AREA=37
Answer: P12* = 0.0164 or 1.64%
Therefore, the probability that it takes more than 12 attempts before he completes a pass is 0.0164 or 1.64%
Step-by-step explanation:
Given;
The quarterback's pass accuracy P= 29% = 0.29
The probability of not completing a particular pass P*
= 1 - 0.29 = 0.71
the probability that it takes more than 12 attempts before he completes a pass implies that the quarterback will not complete his first 12 pass attempts.
The probability that he will not complete the first 12 pass
P12* = (P*)^12
P12* = (0.71) ^12
P12* = 0.0164 or 1.64%
Therefore, the probability that it takes more than 12 attempts before he completes a pass is 0.0164 or 1.64%
