Answer:

0.9 grams

Step-by-step explanation:

The point estimate for the average weight of Soap Bar A is:

$A=\frac{121+122+124+ 123+ 120+ 124+ 121+ 121+ 121+ 123+ 120}{11}\\A=121.82\ grams$

The point estimate for the average weight of Soap Bar B is:

$B=\frac{121+120+122+ 119+ 121+ 122+ 122+ 120+ 120 +121+ 122+123+119}{13}\\B=120.92\ grams$

Therefore, the point estimate for the true difference between the given population means is:

$Dif = A-B\\Dif = 121.82-120.92\\Dif=0.9\ grams$

The point estimate for the difference is 0.9 grams.

Two parallel lines were cut by a transversal. Which of the following

meriva

Answer:

B. a pair of alternate exterior angles with measures of 130° and 50°

Step-by-step explanation:

Alternate exterior angles formed when two parallel lines are cut across by the same transversal line, are said to be congruent.

Therefore, a pair of alternate exterior angles cannot have different angle measures of 130° and 50°. Rather, both alternate exterior angles should be of equal measure of degree.

All other scenarios are possible result except option B: "a pair of alternate exterior angles with measures of 130° and 50°".
