Answer:

B and E are the correct answers.

Step-by-step explanation:

By using the slope formula of y₂₋y₁ / x₂₋x₁ you can find out that the slope is ₋7/4.

Next pick a point to put into point-slope form.

Point-slope form is y₋y₁ = m(x₋x₁) where y₁ and x₁ are a point on the graph and m is the slope.

Substitute both points into the formula (separately) to get B and E as your answers.

Hope this helps!

Sherelle and Venita find two bags of coins in their grandmother’s attic. Each girl selects a bag, takes a random sample of 20 co

Answer:

Step-by-step explanation:

Hello!

The five-number summary comprehends the minimum and maximum values, the 1st and 3rd quartiles and the median.

1st step: is to arrange the data sets from least to greatest.

Sherelle:

26 39 56 58 60 62 65 66 66 68 71 72 72 73 74 75 81 83 84 85

Venita:

44 45 51 51 53 53 55 57 58 62 65 66 69 69 70 73 75 77 78 79

2nd step: To calculate each quartile you have to determine their position and then identify which observation sits in that position:

Quartile 1:

PosQ₁: n/4= 20/4= 5

Quartile 2 (Median)

PosMe: n/2= 20/2= 10

Quartile 3

PosQ₃: n*(3/4)= 20*(3/4)= 15

Since both samples have the same size, the 1st quartile will be the fifth observation of each sample, the median will be the tenth observation and the 3rd quartile will be the fifteenth.

Sherelle:

Q₁: 60

Me: 68

Q₃: 74

Minimum: 26

Maximum: 85

Venita:

Q₁: 53

Me: 62

Q₃: 70

Minimum: 44

Maximum: 79

I hope this helps!

Classify the events as dependent or independent. the events of getting two aces when two cards are drawn from a deck of playing

Thepotemich [5.8K]

The events are dependent.

When the first card is not replaced, you change the probability of the second card. At the very least, you have changed the total number of cards to draw from.

Y is inversely proportional to the cube of x. If Y = 3 when x = 2, find Y, when x is 3. Write a proportion. Solve for y. Show wo

Wittaler [7]

<span>"Y is inversely proportional to the cube of x" translates to Y = kx</span>³ where k is unknown constant. We need to solve for k.

So we have Y = 3 and x = 2. Plug in and we get 3 = k2³ = 8k

So k = 3/8

Now we can solve for Y when x = 3

Y = (3/8)3³ = (3/8)27 = 81 / 8

Final answer: 81 / 8

What is the value of "c" in the quadratic equation 3x 2 + 5x + 7 = 0?

Nutka1998 [239]

Answer:

Step-by-step explanation:

The quadratic equation looks like:

ax + by + c = 0

"c" is the variable that stands for the "constant", or the number that does not have an extra variable attached, and so is "unchanging". In this case, your answer is 7, which is the constant of the equation. Once defined, the number cannot be changed.
