Answer:
p value =0.544
Step-by-step explanation:
Given that in a survey, 33% of the respondents stated that they talk to their pets on the telephone.
(left tailed test at 1% level)
Sample proportion p =
Assuming H0 to be true, std error of proportion
=
p difference = -0.0233
Test statistic Z = p difference/std error
= -0.6067
p value = 0.544
Since p > alpha, we accept H0
Answer:
The triangle should be 16 inches wide.
Step-by-step explanation:
What we know:
- One of the legs measures 12 inches.
- The hypotenuse is 20 inches.
We need to solve for b. Solving for a while b is 12 would also be acceptable.
We will use the first equation.
The triangle should be 16 inches wide.
(f-g)(x) = f(x)-g(x)= 2x²-5-3x-3 = 2x² - 5x - 8 = choice B

Answer:
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
He wants to carpet the living room, which measures 15 ft × 12 1 3 ft. Converting 12 1/3 feet to improper fraction, it becomes 37/3 feet. The square feet of carpet needed to cover the living room is
15 × 37/3 = 185 square feet.
He also wants to carpet the dining room, which is 10 1/4 ft × 10 1/3 ft. Converting 10 1/4 ft × 10 1/3 ft to improper fraction, it becomes 41/4 ft × 31/3 ft. The square feet of carpet needed to cover the dinning room is
41/4 × 31/3 = 1271/12square feet
The number of square feet of carpet will he need to cover both rooms is
185 + 1271/12 = 3491/12
= 20.92 square feet
