1cm means 1 centimeter
centi=1000 so
1cm=1/1000m
1m=1000cm
so 27cm+1m+80cm=27cm+1000cm+80cm=1107cm=1.107m
Answer: 16
Step-by-step explanation:
Answer:
40
Step-by-step explanation:
To find the perimeter, first we need to find the side lengths.
If 100 cm is the area then we need to find what number squared is 100
10 x 10 = 100
So 10 is the side length. P= s + s + s +s
10 + 10 + 10 +10 = 40
Answer:
38.11%
Step-by-step explanation:
Given that:
Mean (μ) = 75, standard deviation (σ) = 5
Z score is a measure in statistics to determine the variation of a raw score from the mean. It is given by the equation:

To calculate the percentage of students scored between a 73 and 78 (C grade), we need to find the z score for 73 and then for 78.
For x = 73, the z score is:

For x = 78, the z score is:

From the probability distribution table:
P(73 < x < 78) = P(-0.4 < z < 0.6) = P(z < 0.6) - P(z < -0.4) = 0.7257 - 0.3446 = 0.3811 = 38.11%
