Answer:
a) The probability that 71 of 150 will prefer boy child is 71/150 or 0.47
b) The result contradicts the poll actual percentage is 47.33% which is 3.33% more than the poll predicted
Step-by-step explanation:
If 71 out of 150 prefer boy child
The probability that the 71 will prefer boy child is
= 71/150
The actual percentage is
(71/150)*100%
= 47.33%
This contradicts the poll as this is more than the poll predicted. That means Less than 71 of 150 actually preferred boy child.

The sequence an = -5 + (n - 1)14 is an arithmetic sequence
The value of a10 is 121
<h3>How to determine the the a10-th term?</h3>
The sequence is given as:
an = -5 + (n - 1)14
To calculate the value of a10, we set n = 10
So, we have:
a10 = -5 + (10 - 1) * 14
Evaluate the difference
a10 = -5 + 9 * 14
Evaluate the product
a10 = -5 + 126
Evaluate the sum
a10 = 121
Hence, the value of a10 is 121

If you are learning about how to calculate the mean of something, than to estimate the height just find the mean, all the peaks added together, and divided by the amount of numbers (27 + 18 + 12 = 57 ... 57 divided by 3 = 19. Your mean is 19)
Factors are the multiplier and the multiplicand in the mathematical operation called multiplication.
Multiple is the any number multiplied by any integer.
Factors of 24:
1, 2, 3, 4, 6, 8, 12, 24
Multiples of 24:
24, 48, 72, 96, 120, so on.
6 is a factor of 24.
36 is neither a factor nor a multiple of 24.
48 is a multiple of 24.
