Answer:

-48.19

Step-by-step explanation:

Given the data:

City Price ($) Sales

River Falls 1.30 100

Hudson 1.60 90

Ellsworth 1.80 90

Prescott 2.00 40

Rock Elm 2.40 38

Stillwater 2.90 32

We could obtain a simple regression model of the data above using a linear regression calculator :

The regression model obtained is :

ŷ = -48.19277X + 161.38554

The change in sales per unit change in price is the value of the slope or gradient :

From the general linear regression equation :

y = mx + c

m = slope ;

Slope = - 48.19 ; hence, there is a drop in sales by about 48 units as the change in sales as the price of candy bar goes up by about $1.00

Answer: 50 Batches

Step-by-step explanation:

16 ounces in a pound

12 pounds times 16 ounces is 192 ounces

192 ounces plus the extra 8 is 200 ounces of flour

200 divided by 4 ounces per batch

200/4= 50

Answer:

50

Step-by-step explanation:

there are 16 ounces in a pound.

at 4 ounces per batch, she can make 4 batches per pound (16/4=4)

so, at 4 batches per full pound, she can make 48 batches (12×4=48)

she can make 2 more batches with the remaining 8 ounces (8/4=2)

so, 48+2= 50 batches

The probability of an impossible event is 0. Because it cannot occur in any situation.

Answer:

25

Step-by-step explanation:

Just by looking at this you can see the answer due to the format. Since all are multiplication you can cross out all the 190s. And you’re left with 75=50+_. Or to solve it, multiply what you were given to get 14250=9500+(190x_). Then subtract 9500: 4750=190x. Then divide by 190: x=25.

Answer:

For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%

Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92

Step-by-step explanation:

there ya go....

Answer:

i think you add all the dogs which give you 2.65+2.46+3.67+2.91 = 11.69%

then for the  chihuahua  you add  3.44/11.69=0.2942= 24.92

Answer:

I think that it is: [5 2] (.25)^2(.75)^3

Step-by-step explanation:

This looks like a binomial distribution problem. The formula for that is:

A common discrete distribution is used in statistics. The probability the individual will win a prize exactly two times out of five is 0.2637.

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

The probability of getting a ball out of the four cups will be,

[tex]P = \dfrac14[/tex]

The probability of not getting the ball out of the four cups will be,

[tex]q = \dfrac34[/tex]

Now, using the binomial distribution the probability the individual will win a prize exactly two times out of five can be written as,

[tex]P(x) = ^nC_x p^xq^{(n-x)}\\\\P(x=2) = ^5C_2 \cdot (\dfrac{1}{4})^2\cdot (\dfrac34)^{(5-2)}\\\\P(x=2) = 10 \cdot \dfrac{1}{16} \cdot \dfrac{27}{64}\\\\P(x=2)=0.2637[/tex]

Hence, the probability the individual will win a prize exactly two times out of five is 0.2637.

Answer:

(5,0) and (0,6)

Step-by-step explanation:

1. Rearrange y as LHS

12x+10y=60

10y=60-12x

y=60/10-12/10x

y=-6/5x+6

2. Find intercepts

x = 0 is y intercept

y = 6

y = 0 is x intercept

-6=-6/5x

6=6/5x

30/6=x

x = 5

3. X-int (5,0) Y-int (0,6)

Answer:

This is called the product.

Step-by-step explanation:

Answer:

The result of a multiplication operation is called a product. The multiplication of whole numbers may be thought of as a repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier.
