pbar=sumnp/sumn

pbar=10+9+11+7+3+12+8+4+6+11/10+10+10+10+10+10+10+10+10+10

pbar=81/1000

pbar=0.081

nbar=sumn/k=1000/10=100

$Standard deviation for pbar chart=\sqrt{\frac{pbar(1-pbar)}{nbar} }$

$Standard deviation for pbar chart=\sqrt{\frac{0.081(0.919)}{100} }$

$Standard deviation for pbar chart=\sqrt{\frac{0.0744}{100} }$

$Standard deviation for pbar chart=\sqrt{0.0007444 }$

Standard deviation for p-chart=0.0273

il63 [147K]

Answer:

55°

Step-by-step explanation:

It is assumed the angles A and C are congruent:

3x + 40 = x + 50
3x - x = 50 - 40
2x = 10
x = 5

m∠A = 3*5 + 40 = 55°

A store uses the expression –2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere from

Rus_ich [418]

Revenue = price * number of backpacks
number of backpacks = -2p + 50

p = 9 ; -2(9) + 50 = -18 + 50 = 32
revenue = 9 * 32 = 288

p = 12 ; -2(12) + 50 = -24 + 50 = 26
revenue = 12 * 26 = 312

p = 12.50 ; -2(12.50) + 50 = -25 + 50 = 25
revenue = 12.50 * 25 = 312.50 GIVES THE MAXIMUM REVENUE

p = 15 ; -2(15) + 50 = -30 + 50 = 20
revenue = 15 * 20 = 300
