Answer:
1/5 chance or 20% chance.
Step-by-step explanation:
When doing this problem we can start with only being able to go for 7 and up. This already makes us go down to a 3/10. Now we have 8, 9, and 10. Only two of those numbers are even 8, and 10. Which gives us a 2/10. 2/10 then simplifies to 1/5.

Probability helps us to know the chances of an event occurring. The probability that the first card is an even number and the card is greater than 7 is 0.15.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability that the first card is an even number and the card is greater than 7 is,
Probability = (5/10)×(3/10) = 15/100 = 0.15
Hence, the probability that the first card is an even number and the card is greater than 7 is 0.15.

Answer:
35.84
Step-by-step explanation:
32x1.12=35.84
Answer:
$35.84
Step-by-step explanation:
Hi! Ace here.
The easiest way to do this is to use benchmark fractions.
10% of 32 = 3.2
1% of 32 = .32
1% of 32 = .32
Add up all the numbers:
3.2 + .32 + .32 = 3.2 + 64 = 3.84
Since it's a mark up, we do:
32 + 3.84 = $35.84
You can also use percent proportions which would look like this. I'm not going to explain it that much because I think that's what the other person did.
[tex]\frac{x}{112} =\frac{32}{100}[/tex]
[tex]x=\frac{112*32}{100} \\\\x=\frac{3584}{100} \\\\x=35.84[/tex]

1. Lily wants to buy 4 pounds of cereal for her camping trip. The boxes are each 18 ounces. According to the number line, how many boxes will she need to buy to have at least 4 pounds? 18 36 72 +++ 26 32 48 80
1: 2 boxes
2: 5 boxes
3: 3 boxes
4: 4 boxes
Answer: 4 boxes.
Step-by-step explanation:
We know that each box has 18 ounces of cereal.
We know that:
1 lb = 16 oz
Then:
1 = (1lb/16oz)
Then we can write:
18 oz = 18oz*(1lb/16oz) = (18/16) lb
This means that each box has (18/16) pounds of cereal.
Now, how many boxes we need to buy if we want to have at least 4 pounds of cereal?
If we buy N boxes, we will have N*(18/16) lb boxes of cereal.
Let's find N such that:
N*(18/16) lb = 4lb
N = 4*(16/18) = 3.56
But you can not have a 0.56 of a box, so we should round our number up to the next whole number, then we get:
N = 4.
She should buy 4 boxes.

4

Answer:
Calzones are $ 8 and an Empanada costs $12
Step-by-step explanation:
2x+3y=52
4x+3y=68
Multiply by -1
-2x-3y=-52
4x+3y=68
combine
2x=16
x=8
plug in 8
4(8)+3y=68
32+3y=68
3y=36
y=12
Step-by-step explanation:
step 1. 2c + 3e = 52, 4c + 3e = 68.
step 2. this is a system of equations. solve the system.
step 3. subtract the 1st equation from the 2nd.
step 4. 2c = 16, therefore c = 8.
step 5. 2(8) + 3e = 52. 3e = 36. e = 12.
step 6. calzones = 8, empanadas = 12.
It has been estimated that a certain stream can support 85,000 fish if it is pollution-free. It has further been estimated that for each ton of pollutants in the stream, 1700 fewer fish can be supported. Assuming the relationship is linear, write the equation that gives the population of fish p in terms of the tons of pollutants x.
Answer:
[tex]p = 85000 - 1700x[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Fish = 85000[/tex]
[tex]Rate = 1700[/tex]
Required
Determine the equation
For 1 ton, there is a reduction of 1700 fishes
This implies that:
For x tons, there will be a reduction of 1700x fishes
So, the function is:
[tex]p = Initial\ Fishes - Rate * x[/tex]
We used minus because the number of fishes reduced.
So, we have:
[tex]p = 85000 - 1700*x[/tex]
[tex]p = 85000 - 1700x[/tex]
Hence, the function is: [tex]p = 85000 - 1700x[/tex]
which of the following is a quadratic equation in one variable. a.7x^2-15=32x b.x^2+y+9=0 c.3x+2y=8. d. 5x -15=0
Answer:
a. 7x^2-15=32x
Step-by-step explanation:
a standard form quadratic equation is written as ax^2+bx+c=0
7x^2-15=32x can be rewritten into 7x^2-32x-15=0 by subtracting 32x on both sides.
options b and c don't work because they include another variable, y
option d is a linear equation, not a quadratic
