The Watson family and the Nelson family each used their sprinklers last summer. The water output rate for the Watson family's sprinkler was 35 L per hour. The
water output rate for the Nelson family's sprinkler was 25 L per hour. The families used their sprinklers for a combined total of 60 hours, resulting in a total
water output of 1700 L. How long was each sprinkler used?
Note that the ALEKS graphing calculator can be used to make computations easier.
Answers
Answer:
We have two variables W and NW= 35 L N = 25L Total: 60 hrs respectfully between W and N Total Water: 1700 L 35W + 25N = 1700 (1)W + N = 60 (2)Just substitute!N = 60 + W 35W + 25(60 + W) = 170035 W + 1500 + 25W = 170060W + 1500 = 170060W = 200 W = 3.33 Now solve for NEvaluate: (4x¹⁴)(8x¹¹) *

Answers
Answer:
D
Step-by-step explanation:
The answer is D because when you look at an ordered pair it is (x , y) the x stands for x-axis and y for y-axis. The x numbers are the ones on the bottom line going horizontally across your screen and the y numbers are the ones on the left side of the graph going up and down. Therefore when you are looking at (1.5 , 9) you start on the bottom line and go to 1.5 then go strait up to 9 on the line on the left and thats where the point is!

The country's population decreased by about 2.4% during this time period.
Since we have given that
In 1990, the number of people = 167 million
In 2010, the number of people = 163 million
We need to find the percent decrease in the country's population during this time.
Percentage would be
New - Original x 100/original
= 163 - 167/167 x 100
= -4/167 x 100
=-2.39%
=-2.4%
Hence, the country's population decreased by about 2.4% during this time period.
Type of problem: Percentage decrease
Step 1: Find the difference between the two numbers
(Difference = original number - new number)
164,000,000 - 155,000,000 = 9,000,000
Step 2: Divide the difference by the original number
9,000,000 / 164,000,000 = 0.05487804878
Step 3: Multiply by 100 and round to find the percent
0.05487804878 x 100 = 5.48780487805
Round to one place = 5.5
Answer: 5.5% decrease in the population

Answers
Answer:
Both of them are right
The amount of carpet needed is 189 7/8 feet
Step-by-step explanation:
Here, we want to get the person with the right calculations step between Michael and Tracy
From what we can see in the question, both exactly have the same calculations
They only differ in the number to put first
So we can say both are right
The amount of carpet needed will be;
12 1/4 * 15 1/2
= 49/4 * 31/2 = 1519/8
= 189 7/8 square feet
Suppose that quiz scores in a beginning statistics class have a mean of 6.6 with a standard deviation of 0.6. Using Chebyshev's Theorem, what is the minimum percentage of quiz scores between 4.8 and 8.4
Answers
Answer:
88.89%
Step-by-step explanation:
Calculation for what is the minimum percentage of quiz scores between 4.8 and 8.4
The calculated minimum percentage value of quiz scores between
First step is to calculate the lower k value using this formula
k=(x1−m)/s
Where:
x1 represent first random value 4.8
x2 represent second random value 8.4
m represent mean 6.6
s represent standard deviation 0.6
Let plug in the formula
k=(4.8−6.6)/0.6
k=−1.8/0.6
k=−3
Second step is to calculate the upper k value
k=(x2−m)/s
k=(8.4−6.6)/0.6
k=1.8/0.6
k=3
Now let calculate the minimum percentage
Using this formula
Minimum percentage=1−1/k^2
Let plug in the formula
Minimum percentage=1−1/3^2
Minimum percentage=1−1/9
Minimum percentage=1−0.1111
Minimum percentage=0.8889*100
Minimum percentage=88.89%
Therefore the minimum percentage of quiz scores between 4.8 and 8.4 is 88.89%
Answer:
75%
Step-by-step explanation:
5.2−6.40.6=−2 and 7.6−6.40.6=2.
This means that 5.2 lies 2 standard deviations below the mean and 7.6 lies 2 standard deviations above the mean.
According to Chebyshev's Theorem, at least 75% of data values lie within 2 standard deviations of the mean.
Therefore, we can say that 75% is the minimum percentage of quiz scores between 5.2 and 7.6.

Corresponding angle are Equal.
Alternate interior Angles are Congruent.
Vertical angles are Congruent.

A frozen yogurt shop has a combination of 150 small and medium sized bowls on their counter. Each small bowl hold 4 ounces and each medium bowl holds 6 ounces. If the bowls on the counter will hold a total of 764 ounces, find the number of small and medium sized bowls on the counter
Answers
The number of small sized bowls on the counter = 68 bowls
The number of medium sized bowls on the counter = 82 bowls
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of small bowls on the counter be = x
Let the number of medium bowls on the counter be = y
The total number of bowls is = 150
So , the equation will be
x + y = 150 be equation (1)
The amount the small bowl can hold = 4 ounces
The amount the medium bowl can hold = 6 ounces
The total amount of all the bowls on the counter = 764 ounces
So , the equation will be
4x + 6y = 764 be equation (2)
Now , on simplifying the equation (1) and equation (2) , we get
Multiply equation (1) by 4 , we get
4x + 4y = 600 be equation (3)
Subtracting equation (3) from equation (2) , we get
2y = 164
Divide by 2 on both sides , we get
y = 82
Therefore the number of medium sized bowl is 82 bowls
Substituting the value of y in equation (1) , we get
x + y = 150
x + 82 = 150
Subtracting 82 on both sides , we get
x = 68
Therefore , the number of small sized bowl is 68 bowls
Hence ,
The number of small sized bowls on the counter = 68 bowls
The number of medium sized bowls on the counter = 82 bowls
