Askydiver parachutes to the ground. the height y (in feet) of the skydiver after x seconds is y=-10x+3000.

1. graph the equation?

2. what does the slope mean in the context of this problem?

3. what does the x and y- intercept mean in the context of this problem?

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

50x5=$250

step-by-step explanation:

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
