ASAP question!
There are four sixth graders and seven seventh-graders in Elsa's chess club. Two members of the club will be chosen at random to attend a tournament with several other chess clubs.
What is the theoretical probability of randomly drawing two sixth graders? What is the theoretical probability of randomly drawing two seventh graders?

Answers

Answer 1

Answer:

2 Six graders: 6/55 chance

2 Seventh graders: 21/55 chance

Step-by-step explanation:

Total: 11 students

6 graders: 4

4/11 for first student and 3/10 for second

4/11 * 3/10 = 12/110 = 6/55

7 graders: 7

7/11 for first student and 6/10 for second

7/11 * 6/10 = 42/110 = 21/55

A net of a square pyramid is shown below. 5.95 cm 5.1 cm What is the surface area, in square centimeters, of the pyramid.

Answers

Answer:

86.7

Step-by-step explanation:

L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7

The surface area of the  square pyramid is 92 square centimeters.

The given figure is a square pyramid.

We have to find the surface area.

Surface area = a² + 2a√(a²/4 + h²)

a is 5.1 cm and h is height which is 5.95 cm.

Surface area = 5.1² + 2(5.1)√(5.1²/4 + 5.95²)

=26.01 + 10.2 √(26.01 /4 +35.4025)

=26.01+10.2 √6.5025+35.4025

=26.01+10.2√41.905

=92 square centimeters.

Answer:

A: 1.5

B: A = n/1.5

C: This means every bowl you make, you would need 1.5 pounds of clay.

Step-by-step explanation:

A: The constant of proportionality is otherwise known as the slope. The formula for the slope is [tex]y_{2}[/tex]-[tex]y_{1}[/tex] / [tex]x_{2}[/tex]-[tex]x_{1}[/tex] (rise over run.) Lets plug the values in.

4.5-0 = 4.5

3-0 = 3

4.5/3 =1.5

B:

A = n/1.5

C:

The point (1,1.5) is representing the x value, the number of bowls, and the y value, the amount of clay in pounds.

This means every bowl you make, you would need 1.5 pounds of clay.

Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation p= -0.5x²+25x-111 models the profit of the fundraiser.​ What's the smallest​ amount, in​ dollars, that you can charge and make a profit of at least ​$114​?

Answers

Answer:

12

Step-by-step explanation:

if we know we want a profit of at least 114, we need to solve for x.

if we put 12 for x we get the answer 117 and when we put 11 for x we get less than 114.

-0.5(12)^2 + 25(12)-111 = 117

Solve [tex]\frac{-72}{x} = 9[/tex] using the distributive property.

Answers

x = -8

Step by Step:

1) -72/x = 9 first, you multiply both sides by x and get -72= 9 * x

2) -72= 9 * x second, you divide both sides by 9 to isolate x by itself -72/9 = 9 * x/ 9 (the 9 cancels on the right side of the equation leaving x by itself)

Leaving you answer to be x = -8

Answer:

The answer is

→ [tex]x=-8[/tex]

Step-by-step explanation:

Given: [tex]\frac{-72}{x} = 9[/tex]

Solve:

[tex]\frac{-72}{x} = 9[/tex]

Step 1: Multiply all terms by the same value to eliminate fraction denominators.

[tex]\frac{-72}{x} = 9[/tex]

⇒ [tex]x * \frac{-72}{x} = x * 9[/tex]

Step 2: Cancel multiplied terms that are in the denominator.

[tex]x * \frac{-72}{x} = x * 9[/tex]

⇒ [tex]-72 = x * 9[/tex]

Step 3: Re-order terms so constants are on the left.

[tex]-72 = x * 9[/tex]

⇒ [tex]-72 = 9x[/tex]

Step 4: Divide both sides by the same factor.

[tex]-72 = 9x[/tex]

⇒ [tex]\frac{-72}{9} = \frac{9x}{9}[/tex]

Step 5: Simplify.

Divide the numbers.

[tex]\frac{-72}{9} = \frac{9x}{9}[/tex]

⇒ [tex]-8 = \frac{9x}{9}[/tex]

Cancel terms that are in both the numerator and denominator.

[tex]-8 = \frac{9x}{9}[/tex]

⇒ [tex]-8 = x[/tex]

Move the variable to the left.

[tex]-8x = x[/tex]

⇒ [tex]x = -8[/tex]

Hence, [tex]x = -8[/tex] is your answer.

During science class, Jack, Jeff, and Jill measure the length of their bean sprouts. Jeff’s sprout is 0.9 times the length of Jack’s, and Jill’s is 1.08 times the length of Jack’s. Whose bean sprout is the longest?Why?

Answers

Answer:

Jill's is the longest.

if jeffs is 0.9 times the length of jacks, his is lesser than jacks. e.g. 2×0.9=1.8. Jeff's will always be shorter. since we know Jacks is over 1, Jill's will always be taller because 2×1.08=2.16 or Jill's length.

explain how the models in questions 4 and 5 are the same

Answers

Answer:

Hi!

So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.

For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.

Hope this helps! :)
