A) the z score for 95% is 1.96
Multiply by the deviation:
1.96 x 0.005 = 0.0098
Now add and then subtract that from the mean:
4.035 - 0.0098 = 4.0252
4.035 + 0.0098 = 4.0448
The interval is (4.0252, 4.0448)
B) 4.035 +/- 1.96 x sqrt( 0.005/sqrt(25))
= 4.035 +/-0.00196
Answer: ( 4.033, 4.037)
C) the conclusion is that both 4.020 and 4.055 are out of the range.
4.020 is below the lowest range and 5.055 is higher than highest range.

Answer:
B
Step-by-step explanation:
20*3=60
20*7=140
20*11=220
He could mow 2 lawns. if he mows 1/3 of the law in 1/6 of an hour, then he can mow 2/3 of the law in 2/6 of an hour. keep adding 1/3 to the amount of lawn mowed as you add 1/6 to the amount of hours, until you hit 6/6 hours, which would be one hour
Answer:
The answer is y= -4x-14
Step-by-step explanation:
y= 1/4x - 7 (-2, -6)
y=1/4x - 7
y=mx+b
y=-4/1x+b
-6=-4(-2)+b
-6=8+b
-8 -8
-14=b
