I need help with Geometry

ehidna [41]

Answer:

We conclude that segment QR is the shortest.

Hence, option B is true.

Step-by-step explanation:

First, we need to determine the missing angle m∠R

Given the triangle Δ∠PQR

m∠P = 48°

m∠Q = 83°

m∠R = ?

We know the sum of angles of a triangle is 180°.

m∠P+m∠Q+m∠R = 180°

48°+83°+m∠R=180°

m∠R = 180° - 48° - 83°

m∠R = 49°

Thus, the value of m∠R = 49°

We know that the longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle.

Here,

m∠P = 48° is the shortest angle.

As the side QR segment is opposite the smallest angle i.e. m∠P = 48°

Therefore, we conclude that segment QR is the shortest.

Hence, option B is true.

Suppose y varies directly as x², and y = 160 when x = 4. Find y when x = 6.

labwork [276]

Finding the constant of proportionality :

y = kx²
160 = k(4)²
k = 10

Finding y when x = 6 :

y = 10(6)²
y = 10(36)
y = 360

The value of y is 360 when x = 6.

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 = $0.28 * 500= 140$

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.
