The solution is, 0.85 is the area under the density curve from 20 to 100.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
given that,
Suppose the sample space for a continuous random variable is 0 to 100. If the area under the density curve for the variable from 0 to 20 is 0.15
The area under the density curves for the continuous random variables always add up to unity.
Thus, the area under the density curve from 20 to 100 is ;
1 - 0.15
which is;
1 - 0.15
= 0.85
Hence, The solution is, 0.85 is the area under the density curve from 20 to 100.

Seth's father is thinking of buying his son a summer movie pass for $30 dollars. With the pass, matiness cost $4 each.
Without the pass each movie is normally $8. If Seth plans to go to 30 movies this summer how much money would he
save?
Answer:
Seth saved $90.
Step-by-step explanation:
1.Find out how much would be spent without buying the movie pass.
Multiply the amount of money that one would spend for each movie, by the number of movies one saw.
8 * 30 = 240
2.Find out the amount that was actually spent
Multiply the amount that was actually spent on each movie, by the number of movies that were seen. Then add the additional cost of the pass.
(4 * 30) + 30
= 120 + 30
= 150
3. Find the difference between the two values.
Subtract the amount that one was supposed to spend by the amount one did spend.
240 - 150
= 90

Answer:
Choice D
Step-by-step explanation:
When you find the unit price it will be easier to eliminate the other choices and to find the unit price I found the easiest numbers to work with, so if we do $5 divided by 2 lbs it'll give us $2.5 and that's our unit price. Then for the graphs we are left with choices C and D. So all we have to do is see which one has the line passing through point (2,5) which stands for 2 oranges and $5.

a store charges 8:95 for an 8 ounce jar of maple syrup.The price for a 10 ounce jar is 12:00. Which jar is better to buy ? What is the difference in the unit prices. If necessary round to the nearest cent
9514 1404 393
Answer:
8-ounce jar is a better buy$0.08Step-by-step explanation:
The price per ounce for the 8-ounce jar is ...
price/ounces = $8.95/8 = $1.11875 ≈ $1.12 . . . per ounce
The price per ounce for the 10-ounce jar is ...
$12.00/10 = $1.20 . . . per ounce
The 8-ounce jar has a lower unit price, so may be better to buy.*
__
The difference in unit prices is ...
$1.20 -1.12 = $0.08
_____
* If you need at most 10 ounces, but more than 8, the 10-ounce jar will have a lower total cost for the amount needed. The "better buy" depends on the context.
15/4- 4 1/3 I'm dumb and i can't figure this out help me plz
Answer:
15/4- 4 1/3
15/4-13/3
45/12-52/12
-7/12
Step-by-step explanation:
Answer:
You are not dumb
Step-by-step explanation:
15/4 - 4 1/3 make the 4 1/3 a improper fraction
15/4 - 13/3 find common denominator of 12
45/12-52/12 since 4 goes into 12 3 times, times the top by 3 to get 45. The second one-3 goes into 12 4 times, so times the top by 4 to get 52.
45/12-52/12= 45-52= -7 put the -7 over the 12
-7/12 that is your answer

Shipping Company A charges $14 plus $2.25 a pound to ship overnight packages. Shipping Company B charges $20 plus $1.50 a pound to
ship an overnight package. For what weight is the charge the same for the two companies?
Let p represent the number of pounds. Select the correct values to write an equation to represent the situation
Answer:
8 pounds
Step-by-step explanation:
Shipping Company A = 14 + 2.25p
Shipping Company B = 20 + 1.50p
Where,
p = the number of pounds.
For what weight is the charge the same for the two companies
Equate the charges of the two companies
14 + 2.25p = 20 + 1.50p
14 - 20 = 1.50p - 2.25p
-6 = -0.75p
Divide both sides by -0.75
p = -6 / -0.75
= 8
p = 8 pounds

Explain how to determine whether a product(answer to a multiplication problem) will be positive or negative. Write in complete sentences
Answer:
when the signs of the two numbers being multiplied are the same, the product answer would be positive.And when the signs of the two numbers being multiplied are different, the product answer would be negative.Step-by-step explanation:
Whether a prdocut will be positive or negative really depends on the signs of the two numbers being multiplied.
In other words,
when the signs of the two numbers being multiplied are the same, the product answer would be positive.(positive number) × (positive number) = positive number
(negative number) × (negative number) = positive number
For example, when we multiply the positive numbers 3 and 4, the product will be positive.
i.e. 3 × 4 = 12
Also, when we multiply the negative numbers 3 and 4, the product will again be positive.
i.e. (-3) × (-4) = 12
And when the signs of the two numbers being multiplied are different, the product answer would be negative.(positive number) × (negative number) = negative number
For example, when we multiply the positive number 3 and negative number -4, the product will be negative.
i.e. (3) × (-4) = -12

Twice the sum of a number and 7 is more than 6 or at most -3. Which compound inequality can represent this relationship?
DA 2(x + 7) > 6 and 2(x + 7) = 3
OB 2(x+7) < 6 or 2(x + 7) 2-3
C 2(x+ 7) < 6 and 2(x + 7) 2-3
D. 2(x + 7) > 6 or 2(x + 7) = -3
The compound inequality that represent the situation is 2(x + 7) > 6 and 2(x + 7) ≤ -3.
How to find compound inequality?Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.
Compound inequality is an inequality that combines two simple inequalities.
Therefore, let's represent twice the sum of a number and 7 is more than 6 or at most -3 with compound inequality as follows:

Kylie's Stationery sells thank-you cards in packs of 6 and birthday cards in packages of 3. Surprisingly, the store sold the same number of each type of card this month. What is the minimum number of each card type that the store must have sold?
Answer:
6 thank you cards and 6 birthday cards
Step-by-step explanation:
x = thank you cards
y = birthday cards
since the same number is sold,
6x = 3y
lcm of 6 and 3 is 6
Therefore 6 thank you cards and 6 birthday cards were sold
Find the intercepts of the function 2x - y = 6.
So the given function is in standard form: Ax + By = C
To find the x-intercept set 'y' to 0 and vice-versa
Solve for x:
2x - 0 = 6
+0 +0
2x = 6

What is the greatest number of 19 cent stickers that can be purchased with a $20 bill, assuming there is no sales tax?
Answer:
105
Step-by-step explanation:
First, you are going to convert dollars to cents. Since there are 100 cents in a dollar, multiple $20 by 100. Now you should have 2,000 cents. Now all you have to do is divide by 19, the cost of the stamps, and you should get 105.26. Because you can't by part of a stamp your answer would be 105.

2x+y=4; x−y=2
Step: Solve 2x+y = 4 for y:
2x + y + −2x = 4 + −2x (Add -2x to both sides)
y = −2x+4
Step: Substitute −2x+4 for y in x−y=2:
x − y=2
x−(−2x + 4)=2
3x − 4=2(Simplify both sides of the equation)
3x − 4 + 4 = 2+4 (Add 4 to both sides)
3x =6
(Divide both sides by 3)
x=2
Step: Substitute2forxiny=−2x+4:
y= −2x + 4
y=(−2)(2) + 4
y=0 (Simplify both sides of the equation)
