Answer:
sample standard deviation is $50
Step-by-step explanation:
Given a population standard deviation of $500 and a random sample of size, n=100.
-The sample standard deviation is calculated using the formula:
Where:
is the sample standard deviation.
is the sample size.
is the population standard deviation
Therefore:
Hence, the sampling distribution has a mean of $1,500 and a standard deviation of $50
Let x be the first computer. Let y be the first computer. We know that Work = 1 / Time.
If the work together, work can be done in 30 seconds. Thus, we have:
1/x + 1/y = 1/30
If x will finish in 50 seconds, we need to compute how many seconds y can finish the same work. Thus solving for y, we have the equation below:
1/50 + 1/y = 1/30
1/y = 1/30 - 1/50
1/y = 1/75
The second computer can finish the same work in 75 seconds.
Answer:
2 is 17.5
Step-by-step explanation:
bc the half of 4 is 2 since 4 is 35 we have to find the half of 35 and how we do that is by dividing it by 2.
35%2=17.5 so 2 is equal 17.5 so <2 is 17.5
Answer:
Area for Triangle is: 1/2bh or bh/2
Area for Trapezoid (As shown in picture):
1/2h(b1+b2)
You’d have to do 1/2 x 18(15+37) for the quesyion in the picture
Hope this helped!
