If Nadia is solving x^2 + 8x =24 by completing the square, what number should she add to
both sides?

Answers

Answer:

Subtract 24 from both sides.

Step-by-step explanation:

x2+8x=24

Step 1: Subtract 24 from both sides.

x2+8x−24=24−24

x2+8x−24=0

For this equation: a=1, b=8, c=-24

Skylar has a bag that contains pineapple chews, apple chews, and peach chews. She performs an experiment. Skylar randomly removes a chew from the bag, records the result, and returns the chew to the bag. Skylar performs the experiment 23 times. The results are shown below:
A pineapple chew was selected 8 times.
A apple chew was selected 9 times.
A peach chew was selected 6 times.

If the experiment is repeated 2000 more times, about how many times would you expect Skylar to remove a peach chew from the bag? Round your answer to the nearest whole number.

Answers

Answer:

522 times

Step-by-step explanation:

a peach chew was chosen 6 out of 23 times so we can create a proportion out of 2000 based on that ratio:

'p' = times peach is chosen out of 2000

6/23 =p/2000

cross-multiply to get:  

23p = 12000

p = 12000/23

p = 522 times

Answer:

522 times

Step-by-step explanation:

From this experiment, Skylar selects a peach chew 6/23 of the time. 6/23*2000=522. This works because 6/23 is the amount of chance Skylar has of selecting a peach chew if she selects one chew. If she selects 2000 chews, therefore, her odds of getting a peach chew would mean that she would get about 522 peach chews.

equation.
- 4x2 - 4x – 1=0
O one imaginary solution
O two real solutions
O one real solution
O two imaginary solutions

Answers

Step-by-step explanation:

the degree of a polynomial determines 1:1 the number of solutions.

a quadratic equation (degree 2) has 2 solutions.

the general solution is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = -4

b = -4

c = -1

so,

x = (4 ± sqrt((-4)² - 4×-4×-1))/(2×-4)

when we look at the square root

16 - 16

we see that it is 0.

the square root of 0 is 0, and there is no difference between -0 and +0.

so, we get only one (real) solution : 4/-8 = -1/2

but : formally, there are still 2 solutions (as this is a quadratic equation). they are just identical.

so, I am not sure what your teacher wants to see in this case as answer.

my answer would be 2 real identical solutions.

Determine whether the situation involves a permutation or combination. Then, find the number of

In how many ways could you choose 3 side dishes from a menu that offers 5 vegetable side dishes
and 3 starches if you want at least one vegetable and one starch?

Answers

The situation involves combination

There are 45 possibilities of choosing the 3 side dishes from the menu

How to determine the number of ways?

The given parameters are

Dishes to choose = 3Vegetable = 5Starch = 3

The keyword choose means that the situation involves combination.

Given that you want at least one vegetable and one starch, the selections are:

(Vegetable, Starch) = (1,2) and (2,1)

So, the number (n) of ways the dishes can be selected is:

n = 5C1 * 3C2 + 5C2 * 3C1

Apply the combination formula on each expression

n = 5 * 3 + 10 * 3

Evaluate the sum

n = 45

Hence, there are 45 possibilities of choosing the 3 side dishes from the menu

The line shown represents the amount of money left on a gift card, y, after Mina buys lattes. After buying 2 lattes, she has $2 left. What is an equation of the line in point-slope form?

Answers

Answer:

[tex]y-2 = -3(x-2)[/tex]

Step-by-step explanation:

Find the diagram to the question attached.

The standard equation of a line in point-slope form is expressed as:

[tex]y-y_0 = m(x-x_0)[/tex] where:

m is the slope of the line

[tex](x_0, y_0)[/tex] is coordinate point on the line

First is to get the slope of the line.

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

If after buying 2 lattes, she has $2 left, hence one of the coordinate of the line is (2, 2). We can get the other coordinates from the graph. From the graph, it can be seen that when x = 0, y = 8. Hence the other coordinates is (0, 8)

[tex]m = \frac{8-2}{0-2}\\m = \frac{6}{-2}\\m = -3[/tex]

Hence the slope is -3

Substitute m = -3 and the point (2, 2) into the formula to get the required equation (note that any of the points can be used)

[tex]y-y_0 = m(x-x_0)\\y-2 = -3(x-2)[/tex]

Hence the equation of the line in point-slope form is [tex]y-2 = -3(x-2)[/tex]

A dartboard consists of a circle inscribed in a square. The area of the circle is square inches. The area of the square is 64 square inches. A dartboard consists of a circle inscribed in a square.

Use 3. 14 for π. 22% 25% 75% 79%.

Answers

The probability  that the dart lands inside the square but not on the circular dartboard is 0.215

What is the probability?

The chances of the happening of any event are called the probability.

The dartboard is in the form of a square and the circle is inscribed in it

The area of the dartboard is  [tex]a_d=54\ inch^2[/tex]

Since the circle is inscribed on the dashboard so the diameter of the circle will be the length of the square  

[tex]a_d=s^2=64[/tex]

[tex]s=\sqrt{64}=8\ inch[/tex]

Thus the diameter of the circle

[tex]d=8\ \ \ r= \dfrac{8}{2} =4 \ inches[/tex]

Now we will calculate the area of the circle

[tex]a_c=\pi r^2[/tex]

[tex]a_c=\ 3.14\times 4^2=50.24\ inch^2[/tex]

The area of the square outside the circle will be the difference of the area of the square and the area of the circle

[tex]64-50.24=13.76\ inch^2[/tex]

Now to find out the probability of the dart hitting outside the circle will be calculated as.

[tex]\rm Probability = \dfrac{Area \ outside \ circle }{Area \ of \ square}[/tex]

[tex]P= \dfrac{13.76}{64} =0.215[/tex]

Thus the probability  that the dart lands inside the square but not on the circular dartboard is 0.215
