Answer:
False
Step-by-step explanation:
√10 * 3 = 3√10
√10 * 3 does not equal √30
It is important to check both conditions
np ≥ 5
nq = n(1 - p) ≥ 5
when you try to approximate a binomial distribution with a normal distribution.
If these two conditions are verified, it means that the sample is "big enough" to use the approximation, otherwise, the normal distribution does not fit well enough the binomial distribution and the values of mean, etc, could be different.
Therefore if those conditions are not verified, the normal distribution is not suitable to represent the binomial distribution.
So you need to know the area of patio in cm, so you need to caculate area and than convert.
4 x 5 = 20 m
20 m = 200000 cm
once you know area, you need to know the area of bricks.
9.5 x 20 = 190
Than divide patio area by brick area
200000 divide 190 = 1052 .63
since there cant be 1052.63 bricks, just round up to 1053.
so 1053 bricks are required for this patio.
Hope this helped!
Answer:
VQU =58°
Step-by-step explanation:
angle QUV is 61 because of F angles (I don't know what they call them in ur country)
triangle QUV is an isosceles triangles so base angles are the same
61+61=122
180-122=58
100(47000-32000)/32000=47% (to nearest percent)
