Mathematics
1 answer:
Ganezh [65]3 years ago
6 0

Answer:

The answer is B.

Step-by-step explanation:

In a linear pair, the total angles is 180°. So we can form an expression for both angles. Let x be the smaller angle and 8x be the larger angle :

x + 8x = 180°

9x = 180°

x = 180° ÷ 9

x = 20°

Next, we have to substitute the x value into the larger angle expression :

8x = 8 × 20° = 160°

Actual lengths of pregnancy terms for a particular species of mammal are nearly normally distributed about a mean pregnancy leng
HACTEHA [7]

Solution :

The data is normally distributed.

The standard deviation is 18 days

Here the data is normally distributed and 54 days is 3 days of standard deviation.

Therefore, the percentage of the births that would be \text{expected to occur} within the 54 days of the mean \text{pregnancy} length is given by :

= P( -3 < Z < 3)

= 0.9544

= 95 %

Therefore, about 95% of the births would be \text{expected to occur} within 54 days of the men \text{pregnancy} length.
