b) Joel
c) Susan, Jan
d) 165.4
173.4
134.5
156
147.3
170.2
Step-by-step explanation:
The standardized normal distribution N (0,1) that expresion stands for normal distribution with mean 0 and standard deviation 1, therefore all positive values are above 0 and all negativa values are below 0
The sample n is 6 then we should use t-student distribution, we calculate t statistic as follow
t = (x-μ)/εε where standard error is εε = σ/√6 εε = 9.795 since σ =24
Robert
0.96 * 9.795 = x - 156 ⇒ x = 165.4
1.78 * 9.795 = x - 156 x = 173.4
-2.2 * 9.795 = x - 156 x = 134.5
0 * 9.795 = x- 156 x= 156
-0.89* 9.795 = x -156 x = 147.3
1.45 * 0.9795 = x -156 x = 170.2
Answer:
60%
Step-by-step explanation:
We have that there are 6 75-W bulbs, that is to say these are the favorable cases. The total cases would be the sum of all the bulbs that would be:
4 + 5 + 6 = 15
Therefore the probability of at least 1 75-W bulbs is:
6/15 = 0.4
Now we must find the probability of at least 2 75-W bulbs, which is like this:
P (examine at least two 75-W bulbs) = 1 - P (examine at most one 75-W bulbs)
Replacing:
P (examine at least two 75-W bulbs) = 1 - 0.4 = 0.6
It means that the probability of least two 75-W bulbs is 60%
The complete question in the attached figure
Part A) find the perimeter
[perimeter of the garden]=[perimeter square 1]+[perimeter a quarter circle]+[perimeter square 2]
[perimeter square 1]=5+5+5-----> 15 ft
[perimeter square 2]=5+5+5-----> 15 ft
[perimeter a quarter circle]=(2*pi*r)/4------> 2*pi*5/4-----> 7.85 ft
[perimeter of the garden]=[15]+[7.85]+[15]-------> 37.85 ft
the answer Part A) isthe perimeter of the garden is 37.85 ftPart B) Find the area of the garden
[Area of the garden]=[Area square 1]+[Area a quarter circle]+[Area square 2]
[Area square 1]=5*5-----> 25 ft²
[Area square 2]=5*5-----> 25 ft²
[Area a quarter circle]=(pi*r²)/4------> pi*5²/4-----> 19.625 ft²
[Area of the garden]=[25]+[19.625]+[25]-------> 69.625 ft²
the answer Part B) isthe Area of the garden is 69.625 ft²
