Answer:
C. 50
Step-by-step explanation:
We are given ΔABC with an altitude BD as shown in the figure.
As it is known that,
<em>'When an altitude is drawn from a right angle of a triangle, then all the three triangles are congruent.'</em>
So, we get that ΔABC ≅ ΔABD ≅ CBD.
Since, the triangles are congruent, their corresponding sides and angles will be congruent.
Moreover, the ratio of the sides will be equal.
So, we get from ΔABC ≅ ΔABD,

i.e.
i.e.
i.e.
i.e. z = 50.
Hence, the value of z is 50.
Answer:
N(24, 3.46)
Step-by-step explanation:
We are given the following in the question:
Percentage of family homes having front poach = 50%
Sample size, n = 48
Normal approximation to the given distribution:
Thus, the distribution of single family homes is best approximated by the normal distribution N(24, 3.46) where mean is 24 and standard deviation is 3.46
