mara is raking leaves. She fills up 7 large bags with them in 3 hours. At this rate, how many bags could she fill in 9 hours?

Answer:

160%

Step-by-step explanation:

Because the first square (the one to the left) is shaded to the brim, it represents 100%.

The second square (the one to the right) is shaded only until the 6th row, we can say that it is shaded 6/10 rows, or 60%.

Lastly, add the percentages of the two squares => 100% + 60% = 160%

Answer:

y = (x + 4.5)² - 13.25

Step-by-step explanation:

y = x² + 9x + 7

We need to get a perfectly squared binomial as part of the right side.

Take the '9x' term, divide it in half, square it, add and also subtract it on the right side, as shown below. That would be (4.5)² = 20.25 added and subtracted.

y = x² + 9x        + 7

y = x² + 9x + 20.25       + 7 - 20.25

y = (x² + 9x + 20.25)  - 13.25

y = (x + 4.5)² - 13.25

y = (x + 4.5)² - 13.25

Vertex Form is y = a(x-h)² + k, where the parabola vertex is (h, k)

So if you wrote this as y = 1(x - [-4.5] )² + (-13.25), we would see that a = 1, and h = -4.5 and k = -13.25.

Vertex = (-4.5, -13.25)

I verified on a graphing calculator that this is indeed the vertex of the parabola.

Answer: Yes, they are mutually exclusive. You cannot have 2+ heads and 0 heads at the same time. They are not independent. The result of 2+ heads nullifies the chance that 0 heads are flipped!

Answer: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3

Step-by-step explanation:

In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.

Then the correct option is d.

Where the degree of the first term is (4 + 1) = 5

The degree of the second term is (2 + 2) = 4

The degree of the third therm is 3.

We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:

-3*x^4*y + 2*x^2*y^2 + 5*y^3

Answer:

The best prediction possible for the number of times both coins will land on heads is 16.

Step-by-step explanation:

For each time the two coins are flipped, there are only two possible outcomes. Either they both land on heads, or they not. Coin flips are independent, which means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

On a trial, probability of two heads.

Each trial has two coins, each with 0.5 probability of landing on heads. So the probability of two heads on a trial is:

[tex]p = (0.5)^2 = 0.25[/tex]

64 times

This means that [tex]n = 64[/tex]

What is the best prediction possible for the number of times both coins will land on heads?

The expected value. So

[tex]E(X) = np = 64*0.25 = 16[/tex]

The best prediction possible for the number of times both coins will land on heads is 16.

Answer:

[tex] - 2x - 2x = 729 + 3 - 27 - 1 \\ [/tex]

x = 11

Step-by-step explanation:

x + 8 = 19        subtract both sides by 8

x = 11

Hey there!

x + 8 = 19

SUBTRACT 8 to BOTH SIDES

x + 8 - 8 = 19 - 8

CANCEL out: 8 - 8 because it give you 0

KEEP: 19 - 8 because it give you the x-value

NEW EQUATION: x = 19 - 8

SIMPLIFY IT!

x = 11

Therefore, your answer is:

x = 11 (Option A)

A linear relationship is a connection that takes the shape of a straight line on a graph between two distinct variables - x and y. When displaying a linear connection using an equation, the value of y is derived from the value of x, indicating their relationship.

The rule is given in the question, as follows:

y is 3 less than x

For each value of x in the first column, the corresponding value of y in the second column can be calculated by subtracting 3 from x.

For example, if x is 10, then y is 3 less than x, which is 7 (10 - 3 = 7).

Similarly, if x is 8, then y is 5 (8 - 3 = 5), and if x is 6, then y is 3 (6 - 3 = 3).
