Sadie and Connor both play soccer. Sadie scored 3 times as many goals as Connor. Together they scored 12 goals. Create and solve an algebraic equation to determine if it is possible for Connor to have scored 4 goals. PLEASE WRITE IN AN ALGEBRAIC EXPRESSION

Let the number of goals Connor scored = x

Sadies scored 3 times as many so you multiply x by 3 to get 3x

Together they scored 12 so now add x and 3x together to equal 13:

X + 3x = 13

Simplify:

3x + x = 4x

4x = 12

Divide both sides by 4:

X = 3

Connor = x = 3

Sadie = 3x = 3(3) = 9

Connor did not score 4 goals.

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

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;
