Answer:
Intervals = (1,064) , (1,036)
Step-by-step explanation:
Given:
Use 95% method
Mean = 1,050
Standard deviation = 7
Find:
Intervals.
Computation:
95% method.
⇒ Intervals = Mean ± 2(Standard deviation)
⇒ Intervals = 1,050 ± 2(7)
⇒Intervals = 1,050 ± 14
⇒ Intervals = (1,050 + 14) , (1,050 - 14)
⇒ Intervals = (1,064) , (1,036)
X1 + x2 / 2 , y1 + y2 / 2
8 + x2 /2 = 6
So x is 4
9 + y2 /2 = 6
So y is 3.
Answer is B ( 4, 3)

Answer:
36
Step-by-step explanation:
9 cookies , 9*4 ((4 because of the 1/4 ))9*4=36
Answer: 17
21-4=17
4+17=21
21+17=38 and so on..
If x=width, then the equation would be:
x(x+10)=20,000
The length is 10 meters longer than the width(x), so the length is x+10.
To get the area(20,000) you multiply width by length, hence x(x+10).
Hope this helps.
