Answer:
16 cm
Step-by-step explanation:
1.6 m = 160 cm
Model length = 160 / 10 = 16 cm
Pyramids and cones have volumes which are one third of their matching cuboids and cylinders.
The volume of this pyramid = (7 x 9 x 10)/3 = 630 / 3 = 210 cu ft
Answer:
The correct answer is A:Let n = k. Then assume that 11" - 6 is divisible by 5. sorry if im wrong but if correct pls mark brainliest
to factor it the answer is (x+1)(x+1)
to simplify it the answer is x2+2x+1
idk if this helped or not but here you go
Answer:
65.04<x<68.96
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = x ± z*s/√n
x is the mean = 67
z is the 95% z score = 1.96
s is the standard deviation = 8
n is the sample size = 64
Substitute;
CI = 67 ± 1.96*8/√64
CI = 67 ± 1.96*8/8
CI = 67 ± 1.96
CI = (67-1.96, 67+1.96)
CI = (65.04, 68.96)
Hence the confidence interval for the mean of the population is between 65.04<x<68.96
