Answer:
(0.55, 0.75)
Step-by-step explanation:
The range can be estimated to be 6 standard deviations wide. Therefore, the standard deviation is:
σ = (0.72 - 0.42) / 6
σ = 0.05
The margin of error is ±2σ, so:
ME = ±0.10
Therefore, the interval estimate is:
(0.65 - 0.10, 0.65 + 0.10)
(0.55, 0.75)
Answer:
2f+9
Step-by-step explanation:
1 and 3 only answer is number 2
Answer:
You are given the width of the garden which is w= 8 feet
length of the garden which l= 6 feet
the width of the walkway is x
so for every side of the garden there is an x
so length overall would be 8+2x (length of garden + x one side + x other side)
and width overall would be 6 + 2x (width of garden + x of one side + x of other side)
area of rectangle is length*width
so the expression would be (8+2x)*(6+2x)

I hope it is correct.
Step-by-step explanation:
The probability of no boys being chosen will be 0.29.
<h3>What is probability?</h3>
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Mr. Larsen's third-grade class has 22 students, 12 girls, and 10 boys.
Two students must be selected at random to be in the fall play.
Then the probability of no boys being chosen will be
Total event = ²²C₂ = 231
Favorable event = ¹²C₂ = 66
Then the probability will be
P = 66 / 231
P = 0.2857
P ≅ 0.29
