To reach a window, you need a ladder to go up 16 feet on the side of your house. You set the bottom of the ladder 4 feet from your house. Which choice is closest to the
shortest ladder you can use to reach the window?

possible solutions:
1. 20 feet 2. 4.5 feet

3. 272 feet 4. 16.5 feet

4. 16.5

Step-by-step explanation:

You solve for the hypotenuse

a^2+b^2=c^2

16^2+4^2=c^2

256+16= the square root of 272

16.5

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1

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;
