Sean wants to estimate the percentage of people who have a yearly physical exam from their physician. He surveys 350 individuals and finds that 238 have a yearly physical exam. What is the correct interpretation of the 95%confidence interval? a. We estimate that 95% of the time a survey is taken, the proportion of people who have a yearly physical exam will be between 0.631 and 0.729. b. We estimate with 95% confidence that the true population proportion of people who have a yearly physical exam is between 0.631 and 0.729. c. We estimate with 95% confidence that the sample proportion of people who have a yearly physical exam is between 0.631 and 0.729.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
