riadik2000 [5.3K]

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 $114-1(5)$ days and $114+1(5)$ days .

i.e. the length of approximately 68% of all pig pregnancies will fall between <u>109 days</u> and <u>119 days</u>.

For the following trapezoid, h = 5 ft, b = 7.9 ft, and B = 14.6 ft. What is the area?

Bond [772]

Answer:

The area of the trapezoid is 56.25² feet.

Step-by-step explanation:

The formula for the area of a trapezoid is $A=\frac{b+B}{2} h$

A = area (of the trapezoid)
b = base of the trapezoid
B = (other) base of the trapezoid
h = height of the trapezoid

*Note: Trapezoids have 2 bases that are parallel to one another, but are not always the same length.

Using the information given to us, we can simply plug in numbers into the equation. By doing so, we'd get $A=\frac{7.9+14.6}{2} 5$ . By plugging this into a calculator, you'd get $A=56.25$ .
