Answer:
Lia collects $ 37.5 , Phil collects $50.3 and Cam collects dollars $ 112.5 .
Step-by-step explanation:
Let us assume that the dollar collect by the Lia be x .
As given
Lia, Phil, and Cam collect a total of 200.30 dollars for a holiday fundraiser.
Phil collects 12.80 dollars more than Lia.
Phil collects dollars = 12.80 + x
As given
Cam collects 3 times as much as Lia.
Cam collects dollars = 3x
Than the equation becomes
x + 12.80 + x + 3x = 200.30
12.80 + 5x = 200.30
5x = 200.30 - 12.80
5x = 187.5
x = $ 37.5
Thus
Lia collects dollars = $ 37.5
Phil collects dollars = 12.80 + 37.5
= $50.3
Cam collects dollars = 3 × 37.5
= $ 112.5
Therefore the Lia collects $ 37.5 , Phil collects $50.3 and Cam collects dollars $ 112.5 .
Answer:
First Choice: As the number of hours spent on homework increases, the tests scores increase.
Step-by-step explanation:
The definition of a positive correlation is a relationship between two given variables, in which both variables are moving in the same direction. This can mean when one variable increases and the other variable increases, too, or one variable decreases and the other decreases as well.
The first choice is a positive correlation because both variables are changing (increasing) in the same direction. As you spend more time on homework, you're likely to get a higher test score.
The second choice cannot be a positive correlation because only one variable is having some kind of change (increasing). The doctor visits amount remains the same, so we can call this a zero-correlation relationship because the number of apples eaten yearly doesn't affect the amount of doctor visits. An apple a day keeps the doctor a way is just a proverb, not to be taken literally.
The third choice cannot be a positive correlation because the two variables are going different directions. Even though the number of times going to bed early is increasing, the number of times waking up late decreases, which is not moving in the same direction as the other variable.
The fourth choice cannot be a positive correlation because, similarly to the third choice, the two variables are going different directions. One variable is increasing, which is the amount of practice time. Meanwhile, the other variable is decreasing (going in the opposite direction), which is the number of games lost in a season.
value of X is 26 Y, is 23, Z is 8
The number of ounces of cereal in the third box is 32.
<u>Explanation:</u>
Given-
10 oy box = $3
Price of 1 ounce box = $3/10
= $0.3
20 oy box = $5
Price of 1 oy box = $5/20
= $0.25
Therefore, it is beneficial to buy a 20 oy box as it is comparatively cheaper than the 10 oy box.
Third box of cereal = $8
$5 is the price of 20 oy box
$8 will be the price of x oy box
So,
Therefore, the number of ounces of cereal in the third box is 32.
