Byers Auto is selling a new minivan that has a base price of $22,510. The
options total $8,062. The dealer's cost is 91% of the base price and 88% of
the options. What is the total dealer's cost.
solve y=f(x) for x then find the input when the output is 6
f(x)=x+9
x = -3
So to figure this out we can readjust the equation to make it easier to solve
[tex]f(x) = x + 9[/tex] is equal to [tex]x+9 = 6[/tex]
From here we can just subtract 9 from both sides and we get our answer!
[tex]x+(9-9) = (6-9)\\x = -3[/tex]

Julie can type 250words in 5 minutes. How long does she take to type 900words
Answer:
18 minutes
Step-by-step explanation:
900/250 is 3.6
3.6 * 5 = 18
Answer:
18 minutes
Step-by-step explanation:
Hi! Okay, let's get started!
Let's find her rate per minute first = 250/50 = 50 words per minute
Now, we need to find the time for 900 words, so we do 900/50, which gives you 18, or 18 minutes!
Hope that helps! :)

What is the exact area of a circle with a circumference of 28?
Answer:
a= 62.39
Step-by-step explanation:
look at the picture above
Answer:
12
Step-by-step explanation:
Area of a triangle = [tex]A=\frac{bh}{2}[/tex]
Where b = base and h = height
The shown triangle has a base length of 3 cm and a height of 8 cm
Using these dimensions we plug in the values into the formula
[tex]A=\frac{3*8}{2} \\3*8=24\\\frac{24}{2} =12\\A=12[/tex]
Hence, the area of the triangle is 12 square centimeters
Answer:
12 centimeters^2
Step-by-step explanation:
We find the area of a triangle by multiplying the base and width of the triangle before dividing by 2
Why because if u put 2 triangles together you get a rectangle
3*8=24
24/2=12

Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the number of individuals in the sample with the specified characteristic, x, for the sample size provided.
Lower bound = 0.298
Upper bound = 0.822
n = 1200
a. The point estimate of the population proportion is _____.
b. The margin of error is _____.
c. The number of individuals in the sample with the specified characteristic is _____.
Answer:
a. 0.56
b. 0.262
c. 672
Step-by-step explanation:
Confidence interval:
A confidence interval has two bounds, a lower bound and an upper bound.
A confidence interval is symmetric, which means that the point estimate used is the mid point between these two bounds, that is, the mean of the two bounds.
The margin of error is the result of the subtraction between these two bounds divided by 2.
a. The point estimate of the population proportion is
Mean of the bounds. So
(0.298 + 0.822)/2 = 0.56
b. The margin of error is
(0.822-0.298)/2 = 0.262
c. The number of individuals in the sample with the specified characteristic is
0.56 of 1200. So
0.56*1200 = 672

What are Exponent and Power?Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.
For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as 34, where 4 is the exponent and 3 is the base.
We know that exponents and power used to express powers.
like if we have 5³ then 5 is multiplied to itself 3 times.
Here we have (-8)² then we can write
(-8)²
= -8 x -8
= 8 x 8
= 64.

1. H0 hypothesis
Since p-value > ∝, H0 is accepted.
Hence the averages of all groups considered to be equal.
Or the difference between the averages of all groups is not big enough to reject H0.
2. P-value
P-value equals 0.999. This means that if we would reject H0, the chance of type1 error (rejecting a correct H0) would be too high i.e (99.99%)
The bigger p-value supports H0.
3. The statistics
The test statistic F equals 0.020, which lies in the accepted range: [-∞ : 2.8477]

Let 'n' be the number of caramel apples are covered with sprinkles.
Thus,we can write
(2/3)*150 + (1/5)*150 + (1/10)*150 + n = 150
100 + 30 + 15 + n = 150
145 + n = 150

Some students reported how many pets they had. The dot plot shows the data collected: A dot plot is titled Students Pets and labeled Number of Pets. The values on the horizontal line are 0, 1, 2, 3, and 4. There are 5 dots above 0, 4 dots above 1, 3 dots above 2, 2 dot above 3, and 1 dot above 4. What do the dots above the number 3 indicate? There are exactly 2 students with 3 pets. There are exactly 3 students with 2 pets. There are exactly 2 students with more than 3 pets. There are exactly 3 students with more than 2 pets.
Answer:
A dot plot is similar to histogram wherein they show the frequency of data. In this kind of plot, instead of bars, dots are stacked on their corresponding bin. The bins here are the number of pets, while the dots are the students. So, the 2 dots above number 3 signifies that, there are two students with three pets. The answer is A.
