Answer:
6. 33% increase
Step-by-step explanation:
Equation of increase/decrease: (Final value-initial value)÷(Initial Value)
6. (66-44)÷(66)=0.33
-Multiply by 100 to get 33% increase
7. (6.5-6)÷(6)=0.083
-Round and multiply by 100 to get 8.0% increase
8. (56-36)÷(56)=0.357
Round and multiply by 100 to get 36% decrease
9. (72-18)÷72=0.75
Multiply by 100 to get 75% decrease
Answer:
from 44 to 66 7 from 6 to 6.5
1415.9090909091%
667 - 44
44
x 100% = 1415.9090909091%
8.3333333333%
6.5 - 6
6
x 100% = 8.3333333333%

Sara missed 7 of 184 school days this year. Approximately what percent of school days was Sara present?
A. 4%
B. 96%
C. 177%
D. 7%
Answer:
B. 96%
Step-by-step explanation:
Sara only missed 7 days of 184 days this year meaning 184 - 7 = 177 and
177 is how many days she attended school, so to figure out percentage take the number of days she attended school and divide by the total amount of days in this year which is 184: 177/184 = 0.96195652173
then multiply by 100 to get percentage so approximately 96%.

The cost of renting a car is $25 per day plus a one-time fee of $75.50 for insurance. How many days can the car be
rented if the total cost is to be no more than $525?
Answer:
the second choice 25x+75.50<525
75.50 + 25x < 525
The car can be rented for 17 days.
On the line you will have a lone pointing to the left with an open circle on 17.
75.50 + 25x < 525
25x < 525 - 75.50
25x < 449.50
x < 449.50/25
x < 17.98

[tex]\boxed {\boxed {\sf x \approx 9.7}}[/tex]
Step-by-step explanation:
This is a right triangle, which we know because of the square in the corner of the triangle. We can use the right triangle trigonometric ratios.
[tex]sin( \theta) =opposite/hypotenuse[/tex] and [tex]cos (\theta) = adjacent /hypotenuse[/tex] and [tex]tan (\theta)=opposite/adjacent[/tex]
First, identify each side of the triangle as adjacent, opposite, or hypotenuse, relative to the 68 degree angle.
The x is next to, or adjacent, to the angle. The 24 is opposite. We are not given the hypotenuse.
[tex]adjacent= x \\opposite= 24 \\hypotenuse= unknown[/tex]
Since we have the adjacent and opposite, we must use tangent.
[tex]tan (\theta)=\frac{opposite}{adjacent}[/tex]
Substitute the values in. The theta (θ) is the angle.
[tex]tan (68)=\frac{24} {x}[/tex]
Solve for x. One way is by cross multiplying.
[tex]\frac{tan(68)}{1}=\frac{24}{x}[/tex]
Multiply the 1st numerator by the 2nd denominator. Then, multiply the 1st denominator by the 2nd numerator.
[tex]tan (68)*x=1*24[/tex]
[tex]tan(68)*x=24[/tex]
Evaluate tan(68) using a calculator.
[tex]2.47508685*x=24[/tex]
Divide both sides of the equation by 2.47508685. This will isolate the variable x. ( We divide because multiplication is occurring between 2.47508685 and x, and division is the inverse of multiplication).
[tex]\frac{2.47508685*x}{2.47508685}=\frac{24}{2.47508685}[/tex]
[tex]x=\frac{24}{2.47508685}[/tex]
[tex]x=9.69662943[/tex]
Round to the nearest tenth. The 9 in the hundredth place tells us to round up. The 6 becomes a 7.
[tex]x \approx 9.7[/tex]
In this right triangle, x is equal to about 9.7
John and his best friend found some money. They split the money evenly, each getting $14. How much money did they find?
Answer:
$28
Step-by-step explanation:
John and his best friend each got $14, so in total there are $14+$14=$28.
Answer:
$28
Step-by-step explanation:
If they split the money evenly then both of them got half.
So, multiply 14 by 2 to find the answer:
(14)(2) = 28
John and his best friend found a total of $28.
I hope this helps!!

1. What can you say about the value of a polynomial
when P(a)=0
Answer:
The expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0
Step-by-step explanation:
The question would be better answered if you gave option. Since there is no option, I'll answer the question generally.
Given
[tex]P(a) = 0[/tex]
The above expression indicates that when polynomial P(x) is divided by divisor x - a, the remainder of the division is 0
Take for instance, the polynomial is:
[tex]P(x) = x^2 - x - 2[/tex]
And the divisor is x - 2, then P(2) = 0 because (x - 2) is a divisor of the equation.
[tex]\frac{P(x)}{x} =\frac{x^2 - x - 2}{x - 2}[/tex]
Factorize the numerator
[tex]\frac{P(x)}{x} =\frac{(x- 2)(x + 1)}{x - 2}[/tex]
[tex]\frac{P(x)}{x} =x + 1}[/tex]
See that x - 2 is a divisor
To check
Set x - 2 to 0
[tex]x -2 = 0[/tex]
[tex]x = 2[/tex]
So, we have:
[tex]P(x) = x^2 - x - 2[/tex]
[tex]P(2) = 2^2 - 2 - 2[/tex]
[tex]P(2) = 4 - 2 - 2[/tex]
[tex]P(2) = 0[/tex]

Drag the tiles to the correct boxes to complete the pairs.
Match each graph with a description of its correlation.
Tiles:
modest negative correlation
weak negative correlation
perfect negative correlation
modest positive correlation
strong positive correlation.
Answer:
Graph 1: perfect negative correlation
Graph 2: modest negative correlation
Graph 3: modest positive correlation
Graph 4: strong positive correlation
Graph 5. weak negative correlation
Step-by-step explanation:
If i'm wrong PLEASE correct me
The graph first is perfect negative correlation, graph second is the modest negative correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
As we know, the coefficient of correlation varies between -1 and +1.
If r = +1 (means the relation between the variable is strong and positive)
If r = -1 (means the relation between the variable is strong but negative)
As we can see in the graph, the line goes down represents the negative correlation and the line goes up represents the positive correlation.
So, we can say:
The first graph is perfect negative correlation.
The second graph is modest negative correlation.
The third graph is modest positive correlation.
The fourth graph is strong positive correlation.
The fifth graph is weak negative correlation.
Thus, the graph first is perfect negative correlation, graph second is the modest negative correlation.
