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 = $0.28 * 500= 140$

Given ACM, angle C=90º. AP=9, PM=12. Find AC, CM, AM.

Gnesinka [82]

Answer:

AM = 25, AC = 15, CM = 20

Step-by-step explanation:

The given parameters are;

In ΔACM, ∠C = 90°, $\overline{CP}$ ⊥ $\overline{AM}$ , AP = 9, and PM = 16

$\overline{AC}$ ² + $\overline{CM}$ ² = $\overline{AM}$ ²

$\overline{AM}$ = $\overline{AP}$ + PM = 9 + 16 = 25

$\overline{AM}$ = 25

$\overline{AC}$ ² = $\overline{AP}$ ² + $\overline{CP}$ ² = 9² + $\overline{CP}$ ²

∴ $\overline{AC}$ ² = 9² + $\overline{CP}$ ²

Similarly we get;

$\overline{CM}$ ² = 16² + $\overline{CP}$ ²

Therefore, we get;

$\overline{AC}$ ² + $\overline{CM}$ ² = 9² + $\overline{CP}$ ² + 16² + $\overline{CP}$ ² = $\overline{AM}$ ² = 25²

2· $\overline{CP}$ ² = 25² - (9² + 16²) = 288

$\overline{CP}$ ² = 288/2 = 144

$\overline{CP}$ = √144 = 12

From $\overline{AC}$ ² = 9² + $\overline{CP}$ ², we get

$\overline{AC}$ = √(9² + 12²) = 15

$\overline{AC}$ = 15

From, $\overline{CM}$ ² = 16² + $\overline{CP}$ ², we get;

$\overline{CM}$ = √(16² + 12²) = 20

$\overline{CM}$ = 20.
