Answer: False.  

Step-by-step explanation:

The slope is the difference in the y coordinates of any two points being divided by the difference between the x coordinates of the same two points.

Using the point,  (0,5) and (3,3)  find the difference in the y coordinates and divide it by the difference in the x coordinates to find the slope.

y:  5 - 3 = 2  

x :  0 - 3 = -3

Slope:  -2/3

This is indeed true because line is going downright  so the slope has to  be negative.

Rachel has 1/2 pound of flour in a container. If the container is 2/5 full, how many pounds of flour can Rachel fit in the entir
Westkost [7]

Answer:

1 1/4 pounds

Step-by-step explanation:

You can write the equation ...

  (1/2) lb = (2/5) × container

Multiplying by the inverse of 2/5 gives ...

  (1/2)·(5/2) lb = container

  5/4 lb = container

  container = 1 1/4 lb

A new building in the shape of a square pyramid is to be constructed. The slant height will be five times the side length of the
Temka [501]

The area of the square pyramid building is the amount of space on it

The maximum base length of the building is 67.42 cm

<h3>How to determine the maximum side length?</h3>

The given parameters are:

Base = b

Slant height (l) = 5b

The lateral surface area is calculated using:

L = 2bl

So, we have:

L = 2 * b * 5b

Evaluate the product

L = 10b^2

The total surface area is calculated using:

T = L + b^2

So, we have:

T = 10b^2 + b^2

Evaluate the sum

T = 11b^2

The maximum surface area is 50,000 square feet

So, we have:

11b^2 = 50000

Divide both sides by 11

b^2 = 50000/11

Take the square root of both sides

b = 67.42

Hence, the maximum base length of the building is 67.42 cm

Suppose that 80% of all registered California voters favor banning the release of information from exit polls in presidential el
natulia [17]

Answer:

a. Mean = 20

Sd = 4

b. Probability of X = 20 = 0.1960

Step-by-step explanation:

we have

n = 25

p = 80% = 0.8

mean = np

= 0.8 * 25

= 20

standard deviation = √np(1-p)

= √25*0.8(1-0.8)

=√4

= 2

probability that exactly 20 favours ban

it follows a binomial distribution

= 25C20 × 0.8²⁰ × 0.2⁵

= 53130 × 0.01153 × 0.00032

= 0.1960

Probability of X = 20 = 0.1960
