Select each pair of equivalent numbers 50/100 and 50%

1/3 and 30%

2/6 and 40%

4/5 and 80%

50/100 and 50%

4/5 and 80%

Step-by-step explanation:

Hope it helps you in your learning process

I would go with 50/100 and 50%, And another will be 4/5 and 80%

Step-by-step explanation: Because 50/100=50% and if you had 2+2+2+2 it would equal 80% put the zero at the end of your process.

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 3 6, because in every triangle the longer side is always shorter than the sum of the other two
