Answer:
Step-by-step explanation:
4(5-2)+(-7)(0.5)
20-8+(-3.5)
12-3.5
8.5
P=5 because the parenthesis mean multiplication, and when you multiply 3 times 5, you receive a product of 15. Then, 15-4 is 11, meaning that p=5.
Answer: The length of approximately 68% of all pig pregnancies will fall between <u>109 days</u> and <u>119 days</u>.
Step-by-step explanation:
According to the empirical rule , 68% of the population falls within one standard deviations from the mean.
Given : For pigs, the length of pregnancies varies according to a normal distribution with a mean of 114 days and a standard deviation of 5 days.
According to the Empirical Rule, the length of approximately 68% of all pig pregnancies will fall between
days and
days .
i.e. the length of approximately 68% of all pig pregnancies will fall between <u>109 days</u> and <u>119 days</u>.
The acceptable first step in simplifying the expression
is (a) 
The expression is given as:

To change the form of the expression, we simply perform several arithmetic operations on it.
Start by multiplying the expression by 1/1

Express 1 /1 as (1 - sec x)/(1 - sec x)

Rewrite the above expression as follows:

Hence, the acceptable first step is (a)
