The second one is 2:8, or 1:4. I am not sure if they want you to actually count each banana, but if so, that would be the answer. For every 2 apples, there are 8 bananas. If you are not supposed to count the bananas, it would be 2:2, or 1:1.
The third one is 15:100, or 3:20 in simplest form. For every 15 sixth grade teachers, there are 100 sixth grade students.

Which of the following describes events that are dependent?
The first child in a family is a boy. The second child is also a boy.
Without looking, you select a blue marble from a bowl. You return the marble to the bowl and then draw a red
marble.
You choose a red card from a deck of 52 cards and keep it. Then you choose another red card.
A boy rolls a 5 on a six-sided die. The boy rolls the die again and gets another 5.
Answers
The correct answer would be option (A) because the family would be dependent.
What are dependent Events?A dependent Event is defined as if the outcome of one event has bearing on the outcome of the other, the two events are said to be dependent events. Or, we may say that an event is considered dependent if it does affect the probability of another event. Probability-dependent is dependent on occurrence.
What is probability?The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
According to option (A),
The first child in a family is a boy. The second child is also a boy.
A boy is the family's youngest. Another boy is the second child.
Here the family would be the dependent.
Hence, the correct answer would be an option (A).

The mean distance that and Tina drove was 153 kilometers.If Ben drove 24 kilometers more than Tina,what was the distance that Tani drove?
Answers
Answer:
141 km
Step-by-step explanation:
Given data
Mean distance= 153km
Let Tina dirve=x km
Ben= x+ 24
Number of participants= 2
Hence,
Mean= total distance/number of participants
153= x+24+x/2
cross multiply
153*2= x+24+x
306 =2x+24
306-24= 2x
282=2x
Divide both sides by 2
x= 282/2
x= 141km
Hence Tina drove 141 km

10. Kate and Sophia are selling raffle tickets for a fundraiser.
Kate has sold 4 less than twice as many as Sophia.
If the two girls have sold a total of 38 tickets,
how many has each girl sold? equation and answer
Answers
Answer:
Sophie sold 14
Kate sold 24
Step-by-step explanation:
Kate has sold 4 less than twice as many as Sophia.
2s - 4
---------------------
sold a total of 38 tickets
Sophie + Kate = 38
s + (2s - 4) = 38
Combine like terms
3s - 4 = 38
Add 4 to both sides
3s = 42
Divide both sides by 3
s = 14
2s - 4 = 2*14 - 4 = 24

Which name best describes the polygon with vertices (0, 0), (4, 8), (12, 8), and (16, 0)? A) Triangle C) Trapezoid B) Square D) Pentagon
Answers
Answer:
C) Trapezoid
Step-by-step explanation:
Given
[tex]A = (0,0)[/tex]
[tex]B = (4,8)[/tex]
[tex]C = (12,8)[/tex]
[tex]D=(16,0)[/tex]
Required
The possible shape
The above are 4 vertices.
Hence, the shape cannot be
(a) Triangle ---- it has 3 vertices
(b) Pentagon ---- it has 5 vertices
Calculate distance AB using distance formula
[tex]AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
Where:
[tex]A = (0,0)[/tex]
[tex]B = (4,8)[/tex]
[tex]AB = \sqrt{(0 - 4)^2 + (0 - 8)^2[/tex]
[tex]AB = \sqrt{( - 4)^2 + ( - 8)^2[/tex]
[tex]AB = \sqrt{16+64[/tex]
[tex]AB = \sqrt{80[/tex]
[tex]AB = 8.94[/tex]
Calculate distance BC using distance formula
[tex]BC = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
Where:
[tex]B = (4,8)[/tex]
[tex]C = (12,8)[/tex]
[tex]BC = \sqrt{(4 - 12)^2 + (8 - 8)^2[/tex]
[tex]BC = \sqrt{(-8)^2 + (0)^2[/tex]
[tex]BC = \sqrt{64 +0[/tex]
[tex]BC = \sqrt{64[/tex]
[tex]BC = 8[/tex]
Since
[tex]AB \ne BC[/tex]
Then, the polygon is not a square
