Answer:
confidence interval =(0.10,0.16)
Step-by-step explanation:
Given that sample proportion was
26/200 =0.13 for a sample size of 200
Margin of error is given as 0.03
We know that confidence interval is one which is calculated as sample proportion ±Margin of error
Here sample proportion=0.13
Margin of error = 0.03
Hence
confidence interval lower limit = 0.13-0.03 = 0.10
Confidence interval upper limit = 0.13+0.03 = 0.16
Hence confidence interval =(0.10,0.16)
50x+75=65x
Now divide
15x=75/15

The height in feet of the tree is 111.5 ft.
<h3>How to find the height of a tree?</h3>
The height of a house is 52 ft.
A tree beside the house is 7.5 ft more than twice as tall.
The height of the tree is as follows:
let
x = height of the house
Therefore,
The height of the house = x = 52 ft
Hence,
height of the tree = 7.5 + 2x
height of the tree = 7.5 + 2(52)
height of the tree = 7.5 + 104
height of the tree = 111.5
height of the tree = 111.5 ft

You can get this answer bye dividing the two numbers
9.125×10^2÷9.125×10^-3
Cancel the 9.125 to 9.125 and u will remind with 10^2÷10^-3
Exponent divided by exponent.
2-(-3)=5
10^5=100,000
9.125×10^-3 is 100,000 times less than 9.125×10^2
I think it will help
The first answer is C because the prompt says the total was lessthan 13. Also, the cost of the necklace is added to the cost, not subtracted.
5b+3.5<13
5b<9.5
b<1.9
Because it must be less than 1.9, the highest possible price is $1.89
