Mario’s younger brother is 2 3/4 tall. mario is 1 3/4 feet taller than his younger brother. which number line represents mario’s height, in feet?

Graph A - 4 1/2 feet

Step-by-step explanation:

Since Mario is taller that his younger brother - add the two heights together.

2 3/4 + 1 3/4 =

I added the whole numbers first 2 + 1 = 3; then the fractions 3/4 + 3/4 = 1 1/2

Add 3 + 1 1/2 = 4 1/2

1. minimum

2. 6400

3. eight

hope this !

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;
