The Dolphins football team gained 16 yards on their first play, then lost 11 yards on the next play. Write an addition expression to represent this situation. Find the sum and explain its meaning.

On the first play, Dolphin's football team gained 16 yards.

On the 2nd play, Dolphin's football team lost 11 yards.

Therefore, the addition expression to represent this situation is:

The sum of this expression is:

Therefore, we can interpret it as: Dolphin's football team gained 5 yards over the 2 plays

Answer : The team Dolphins gained 5 yards over the 2 plays.

Step-by-step explanation:

Given information is -

The Dolphins football team gained 16 yards on their first play

And then lost 11 yards on the next play.

Means they had 2 plays.

When we have two conditions and have to apply addition expression, we put brackets around A and B as they are expressions, and not simply numbers.

Then the addition is supposed to apply to whatever A and B may contain.

So, the addition expression to represent this given situation is:

= 5

Answer : The team Dolphins gained 5 yards over the 2 plays.

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;
