Isabella has 7 yards of ribbon to make bows. Each bow is made from a peace of ribbon that is 1/2 yard long. How many bows can Isabella make?

14 bows

Step-by-step explanation:

Isabella has 7 yards of ribbon to make bows. Each bow is made from a peace of ribbon that is 1/2 yard long. How many bows can Isabella make?

The above question is calculated as:

1/2 yard of ribbon = 1 bow

7 yards of ribbon = x bows

We cross multiply

1/2 yard of ribbon × x bows = 7 yards of ribbon × 1 box

x bows = 7 yards of ribbon × 1 box/1/2 yard of ribbon

x bows = (7 ÷ 1/2 ) bows

x bows = 7 × 2 bows

= 14 bows

Therefore, Isabella can make 14 bows

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;
