Answer:

-4

Step-by-step explanation:

7 + (-11) basically translates to 7 - 11.  Since the bigger number has the negative sign here, you just have to subtract 11-7 and then add the negative onto the answer.

Answer:

-4

Step-by-step explanation:

7-11

-4

if it is a number + a negative number you remove the +and just subtract

Answer:

15x^2-14x-4

Step-by-step explanation:

(8x^2 * x-7x+2)+(7x^2 -7x-6)

you take out the parentheses

you add the common ones so -7x+-7x= -14x

8x^2 +7x^2 = 15x^2

and 2-6= -4

so in total it's 15x^2-14x-4

Answer: 11x^2 -16x-3

Step-by-step explanation:

Solution:

Your problem → (8x^2-7x+2) + (3x^2-9x-5)

(8x2-7x+2)+(3x2-9x-5)

=8x2-7x+2+3x2-9x-5

=8x2+3x2-7x-9x+2-5

=11x2-16x-3

Answer:

17/50

Plzzzz give me Brainliest!  

The probability that both erasers chosen were blue is 3/25.

To find the probability that both erasers chosen were blue, we need to determine the favorable outcomes (choosing two blue erasers) and the total possible outcomes.

There are a total of 25 erasers in the cup: 7 red erasers + 4 yellow erasers + 9 blue erasers + 5 green erasers = 25 erasers.

To calculate the probability, we consider the events of choosing a blue eraser without replacement.

For the first pick, there are 9 blue erasers out of 25 total erasers.

After the first blue eraser is chosen, there are 8 blue erasers remaining out of 24 total erasers.

The probability of choosing a blue eraser on the first pick is 9/25.

The probability of choosing a blue eraser on the second pick, without replacement, is 8/24.

To find the probability of both events occurring (both erasers chosen being blue), we multiply the probabilities together:

(9/25) * (8/24) = 72/600 = 6/50 = 3/25

Therefore, the probability that both erasers chosen were blue is 3/25.

Answer:

I think the answer is B

Step-by-step explanation:

(I'm not great at math so pls don't use my answer unless its a last resort) Because when I divided each one they all ended up back at 4, with that being said; 4 ÷ 1 = 4 , 8 ÷ 2 = 4, 12 ÷ 3 = 4, and 16 ÷ 4 = 4. Those are in the c column.

Answer:

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which  is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.

Answer:

a: As the x-values increase, the y-values tend to increase.

Positive Correlation

Step-by-step explanation:

The graph shown as a positive correlation.

Two variables move in the same direction in a positive correlation.

You can also tell that the graph has a correlation that is positive because of the line moving in a upward direction from left to right.

Step-by-step explanation:

Answer:

h=200

Step-by-step explanation:

h/10+5=25

h/10=20

h=200

h/10 + 5 = 25

Subtract 5 from each side to get h/10 alone.

h/10 + 5 - 5 = 25 - 5

h/10 = 20

Multiply both sides by 10 to get h alone.

h/10 • 10 = 20 • 10

h = 200

h = 200. I hope this helps!

Step-by-step explanation:

10+12=22

==========================================

Explanation:

1/2 = 0.5

Every 60 days, the amount cuts in half.

We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.

After another 60 days, we have 452*0.5 = 226 grams left over.

-------------

Alternative Method:

We can apply the half-life formula.

y = a*(0.5)^(x/H)

where,

In this case,

When x = 120 days go by, we have....

y = a*(0.5)^(x/H)

y = 904*(0.5)^(x/60)

y = 904*(0.5)^(120/60)

y = 904*(0.5)^(2)

y = 904*(0.25)

y = 226 grams of antimony left over.

This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.
