Crank

Answer:

Angle BOC = 28; Angle AOB = 21

Step-by-step explanation:

Because angle AOC = AOB + BOC you can set the equation:

2x+10 + 4x-15 = 49

<solve for x>

6x - 5 = 49

6x = 54

x= 9

<plug in x for the angles>

BOC = 2(9) +10 = 28

AOB = 4(9) - 15 = 21

A local bakery sells cookies for 5.50 per pound and brownies for 7.50
uysha [10]

Answer:

I may be wrong but i think the answer is D

Step-by-step explanation:

We know that y=10, so if we were to multiply 10 by 7.50, it would be 75, not 63, so A and B wouldn't be correct. and we don't know the value of x, so I think D is the best answer.

54% of U.S. adults have very little confidence in newspapers. You randomly select 10 U.S. adults. Find the probability
Degger [83]

Part B is not clear and the clear one is;

P(X ≥ 6)

Answer:

A) 0.238

B) 0.478

C) 0.114

Step-by-step explanation:

To solve this, we will make use of binomial probability formula;

P(X = x) = nCx × p^(x)•(1 - p) ^(n - x)

A) 54% of U.S. adults have very little confidence in newspapers. Thus;

p = 0.54

10 random adults are selected. Thus;

P(X = 5) = 10C5 × 0.54^(5) × (1 - 0.54)^(10 - 5)

P(X = 5) = 0.238

B) P(X ≥ 6) = P(6) + P(7) + P(8) + P(9) + P(10)

From online binomial probability calculator, we have;

P(X ≥ 6) = 0.2331 + 0.1564 + 0.0688 + 0.01796 + 0.0021 = 0.47836 ≈ 0.478

C) P(x<4) = P(3) + P(2) + P(1) + P(0)

Again with online binomial probability calculations, we have;

P(x<4) = 0.1141 ≈ 0.114
