Answer:
A) The probability is 0.95 that the percent of adults living in the United States who are satisfied with their health care plans is between 63.6% and 68.4%.
Step-by-step explanation:
A polling agency reported that 66 percent of adults living in the United States were satisfied with their health care plans. The estimate was taken from a random sample of 1,542 adults living in the United States, and the 95 percent confidence interval for the population proportion was calculated as (0.636, 0.684).
This means that we are 95% sure that the true proportion of adults living in the United States who were satisfied with their health care plans is between 0.636 and 0.684.
So the correct answer is:
A) The probability is 0.95 that the percent of adults living in the United States who are satisfied with their health care plans is between 63.6% and 68.4%.
Sinα=h/L
α=arcsin(h/L)° we are told that h=18 and L=20 so
α=arcsin(9/10)°
α≈64° (to nearest whole degree)
Answer: The cost per person would be $15.20.
Step-by-step explanation: The price $40 per person when you have 5 people, is 8,8x the price per person. So, if you have 6 people more, you have 8,8x6 less in the price.
8,8 x 6 = 52,80.
44 x 5= 220,00. That was the cost for the limo for 5 people.
It means 220,00 - 52,80 = 167,20 (new price for 11 people)
167,20 ÷ 11 (new price per person) = 15,20.

Answer:
y = - 3x + 26
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 5 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (6, 8 ) into the partial equation
8 = - 18 + c ⇒ c = 8 + 18 = 26
y = - 3x + 26 ← equation of parallel line
