What is 60= 3/4h i am doing bim (big ideas math online) i need plz

h=80 is the final answer. *The answer must be have a positive sign.*

Explanation:

Switch sides of an equation.

3/4h=60

multiply by 4 both sides of an equation.

4*3/4h=60*4

simplify.

3h=240

divide by 3 both sides of an equation.

3h/3=240/3

simplify.

240/3=80

80*3=240

3*80=240

240/80=3

h=80

Hope this helps!

Thanks!

Have a great day!

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;
