Answer:

112

Step-by-step explanation:

Expected Value is anticipated value, calculated by multiplying each of possible outcomes with their probability of occurrence.

If Price has = 60% chance of value 120 , & 40% chance of value 100

Expected Value = Sum ( Probability of outcome x Payoff )

E (X) = Σ [ xi . PR ( xi ) ] =  x1. Pr (x1) + x2 . Pr (x2)

= 0.6 (120) + 0.4 (100) = 72 + 40

= 112

Answer:

The slope is -3 and the y intercept is -2

Step-by-step explanation:

3x + y = -2

Solve for y

Subtract 3x from each side

3x-3x + y =-3x -2

y = -3x-2

This is in slope intercept form

y = mx+b  where m is the slope and b is the y intercept

The slope is -3 and the y intercept is -2

Answer:

slope is up 3 over 1, and y int is y =3x + 2

Step-by-step explanation:

y = 3x + 2

Step-by-step explanation:

(4s+2)(5s^2+10s+3)

=(4s+2)(5s^2+10s+3)

=(4s)(5s^2)+(4s)(10s)+(4s)(3)+(2)(5s^2)+(2)(10s)+(2)(3)

=20s^3+40s^2+12s+10s^2+20s+6

Answer:The four gospels that we find in the New Testament, are of course, Matthew, Mark, Luke, and John. The first three of these are usually referred to as the "synoptic gospels," because they look at things in a similar way, or they are similar in the way that they tell the story.

Answer:

Zeroes: x=4, x=-1/2, and x=6

Step-by-step explanation:

Use Synthetic Division where x-4=0 to find another factor:

4 | 2 -19 +38 +24

  ___8_-44_-24

    2 -11  -6  |   0

So far, your two factors are x-4 and 2x^2-11x-6.

We can actually factor 2x^2-11x-6 into (2x+1)(x-6), so we have three factors which are (x-4), (2x+1), and (x-6)!

By the Zero Product Property, x=4, x=-1/2, and x=6 are your zeroes.

Answer:

C. n = 90; p = 0.8

Step-by-step explanation:

According to the Central Limit Theorem, the distribution of the sample means will be approximately normally distributed when the sample size, 'n', is equal to or larger than 30, and the shape of sample distribution of sample proportions with a population proportion, 'p' is normal IF n·p ≥ 10 and n·(1 - p) ≥ 10

Analyzing  the given options, we have;

A. n = 45, p = 0.8

∴ n·p = 45 × 0.8 = 36 > 10

n·(1 - p) = 45 × (1 - 0.8) = 9 < 10

Given that for n = 45, p = 0.8, n·(1 - p) = 9 < 10, a normal distribution can not be used to approximate the sampling distribution

B. n = 90, p = 0.9

∴ n·p = 90 × 0.9 = 81 > 10

n·(1 - p) = 90 × (1 - 0.9) = 9 < 10

Given that for n = 90, p = 0.9, n·(1 - p) = 9  < 10, a normal distribution can not be used to approximate the sampling distribution

C. n = 90, p = 0.8

∴ n·p = 90 × 0.8 = 72 > 10

n·(1 - p) = 90 × (1 - 0.8) = 18 > 10

Given that for n = 90, p = 0.9, n·(1 - p) = 18 > 10, a normal distribution can be used to approximate the sampling distribution

D. n = 45, p = 0.9

∴ n·p = 45 × 0.9 = 40.5 > 10

n·(1 - p) = 45 × (1 - 0.9) = 4.5 < 10

Given that for n = 45, p = 0.9, n·(1 - p) = 4.5 < 10, a normal distribution can not be used to approximate the sampling distribution

A sampling distribution Normal Curve

45 × (1 - 0.8) = 9

90 × (1 - 0.9) = 9

90 × (1 - 0.8) = 18

45 × (1 - 0.9) = 4.5

Now we will investigate the shape of the sampling distribution of sample means. When we were discussing the sampling distribution of sample proportions, we said that this distribution is approximately normal if np ≥ 10 and n(1 – p) ≥ 10. In other words

Therefore;

A normal curve can be used to approximate the sampling distribution of only option C. n = 90; p = 0.8

Answer:

50 degrees

Step-by-step explanation:

90 + 40 = 130

180 - 130 = 50

Make sure your calculator is in degree mode.

cos(angle) = adjacent/hypotenuse

cos(37) = 30/x

x*cos(37) = 30

x = 30/cos(37)

x = 37.5640697  approximately

x = 37.6

Answer:

3 and -2

Step-by-step explanation:

To get to -6, it has to be 3 and -2 because 3 x -2 = -6 and also 3 + (-2) = 1
