If you assume the samples are representative how many whole wheat bagels might you infer are sold at each store

Alexxandr [17]

Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.

We find fraction of whole wheat bagels to the sample for each shop using given information

Shop A = $\frac{10}{50} = 0.20$

Shop B = $\frac{23}{100} = 0.23$

Shop C = $\frac{7}{25} = 0.28$

The number of whole wheat bagels for each shop that sells 500 bagels per day

Shop A = $0.20 * 500= 100$

Shop B = $0.23 * 500= 115$

Shop C = $0.28 * 500= 140$

43×15= what is the correct answer

mario62 [17]

43 × 15 = 645.

First, set up the long multiplication.
Second, calculate 3 × 5, which is 15. Since 15 is two-digit, carry the first digit 1 to the next column.
Third, calculate 4 × 5 which is 20. Since 21 is two-digit, carry the first digit 2 to the next column.
Fourth, bring down the carry digit of 2.
Fifth, calculate 3 × 1, which is 3.
Sixth, calculate 4 × 1, which is 4.
Seventh, calculate 215 + 430, which is 645.
Eighth, therefore, 43 × 15 = 645.

Or.. an easier way is to use a calculator. They always come in handy when doing multiplication.
