Use the graph to find the indicated function value y=f(x). Find f(-2)
Answer:
f(-2)=3
Step-by-step explanation:
we know that
f(-2) is the value of the function f(x) for the value of x equal to -2
so
Observing the graph
For x=-2
f(-2)=3
The result is found by substituting -2 into the equation of the function. Using the provided line of best fit equation, we find f(-2) to be approximately -3207.324, but this is just an approximation.
Explanation:To find f(-2) using the given equations, we first identify the equation associated with the given function, which in this case, is not explicitly provided in the given information. By convention, the general format for a linear function is y=f(x). The value is found by substituting the value of x into the equation and solving for y.
However, since the equation of the function isn't provided but we have details about the line of best fit, we could use that if it closely represents the graph of our function. In the case of the line of best fit given as ŷ = −3204 + 1.662x, we simply plug in -2 for x:
ŷ = -3204 + 1.662*(-2) = -3204 - 3.324 = -3207.324
So, if we were using this line of best fit as a representation for our function f(x), then f(-2) would be approximately -3207.324. Always remember though, that the line of best fit is an approximation and the real value might slightly differ based on the actual function.

Answer:
[tex]x_1=-6.9\\x_2=0.9[/tex]
Step-by-step explanation:
The first step is to move all the terms from the right side to the left side of the equation and then add the like terms:
[tex]2x^2+12x-16=-3\\\\2x^2+12x-16+3=0\\\\2x^2+12x-13=0[/tex]
Now we can apply the Quadratic formula. This is:
[tex]x=\frac{-b\±\sqrt{b^2-4ac}}{2a}[/tex]
In this case we can identify that:
[tex]a=2\\b=12\\c=-13[/tex]
Finally, we must substitute these values into the Quadratic formula. Then we get:
[tex]x=\frac{-12\±\sqrt{((12)^2-4(2)(-13)}}{2(2)}[/tex]
[tex]x_1=-6.9\\x_2=0.9[/tex]
Mrs. Roberts poured 2 glasses of lemonade. The first glass contained 5 oz of lemon juice and 8 oz of water. The second glass contained 3 oz of lemon juice and 7 oz of water. Which glass of lemonade had a stronger lemon flavor? Show me or explain to me how you know. (Prove to me that your answer is correct!)
Answer:
The first glass
Step-by-step explanation:
I believe that first, you must find the ratio of lemonade to water in each glass.
[Remember that you can write a ratio in 3 ways (assume that x and y are numbers):
x : y
x / y
x to y
Now, our first glass of lemonade can be written as 5/8. If you were to write 5/8 as a decimal, you'd get 0.625.
Now, our second glass of lemonade can be written as 3/7. If you were to write 3/7 as a decimal, you'd get 0.428 (I rounded it to the nearest thousandth.)
0.625 > 0.428
0.625 is greater than 0.428, so therefore, the first glass had a stronger lemon flavor.
I hope this helps! :)
Step-by-step explanation:
The first glass has a total volume of 5 oz + 8 oz = 13 oz. Of the 13 oz, 5 oz is lemon juice, so the fraction of lemon is 5/13.
The second glass has a total volume of 3 oz + 7 oz = 10 oz. Of the 10 oz, 3 oz is lemon juice, so the fraction of lemon is 3/10.
We need to compare these fractions. To do that, we need to find the common denominator. In this case, 10×13 = 130.
5/13 = 50/130
3/10 = 39/130
So the first glass has the stronger lemon flavor.

Hugh brought some magazines that cost $3.95 each and some some books that cost $8.95 each. He spent a total of $47.65 let m represent the number of magazines and b represent the number of books. Which equation models the situation
Answer:
3.95m + 8.95b = 47.65
Step-by-step explanation:
From this problem, you get quite a handful of information.
The variable "m" represents the # of magazines Hugh bought.
The variable "b" represents the # of books Hugh bought.
One magazine [m] cost $3.95
One book [b] cost $8.95
The total cost of books and magazines is $47.65
Based on the information, you can create an equation with two variables, representing the total cost and how many of each magazine and book Hugh bought.
If one magazine cost $3.95, the amount of money he spent on magazines can be represented by 3.95m.
If one book cost $8.95, the amount of money he spent of magazines can be represented by 8.95b.
And lastly, if the total cost of magazines and books Hugh bought is $47.65, the following equation can be made:
3.95m + 8.95b = 47.65
So, "3.95m + 8.95b = 47.65" is the correct equation. I hope this helps! :)

Marc bought a pair of sneakers and a sweatshirt for $120. If the sweatshirt cost one-half the price of sneakers, find the cost of each
Answer:
The pair of sneakers cost 80 dollars.
The sweatshirt costs 40 dollars.
Step-by-step explanation:
Let x represent the pair of sneakers
Let y represent the sweatshirt
x + y = 120
The sweatshirt costs one-half the price of sneakers, which is represented by:
y = 1/2(x)
Use the substitution method
x + y = 120
x + 1/2(x) = 120
Multiply the equation by 2
2x + x = 240
3x = 240
x = 80
The cost of the sneakers is 80 dollars
To determine the cost of the sweatshirt subtract 120 by 80/
120 - 80 = 40
The cost of the sweatshirt is 40 dollars
According to the general equation for conditional probability, if P(A n B) = 3/10 and P(B)= 2/5 what is p(alb)
Answer:
P(A given B) = 3/4
Step-by-step explanation:
As we know that it is conditional probability, where the probability of an event depends on the event that has certain probability of occurrence.
The formula for conditional probability is:
P(A given B) = P(A ∩B) / P(B)
Where a and B are events. The probability of event B is known and we also know probability of A∩B
So, putting the values in the formula:
[tex]P(A\ given\ B) = \frac{P(A and B)}{P(B)}\\= \frac{\frac{3}{10} }{\frac{2}{5} } \\=\frac{3}{10} *\frac{5}{2}\\=\frac{3}{4}[/tex]
So, the probability of A given B is 3/4 ..

Sam bought brushes for $8, a palette for $5, and oil paints for $15. He paid $29.82 in all. What sale-tax rate did Sam pay?
Add the cost of the three items:
8 + 5 + 15 = $28
Subtract that amount from the total:
29.82 - 28 = $1.82 ( amount he paid in tax)
Divide the tax amount by the cost of the items:
1.82 / 28 = 0.065
Multiply that by 100:
0.065 x 100 = 6.5% sales tax rate
What’s the median?
8.74, 3.44, 6.09, 5.0
Answer:
5.545
Step-by-step explanation:
place them in order
3.44, 5.0, 6.09, 8.74
since there are four numbers you add the middle two together and divide in half.
5.545
Median means middle. You must find the middle of this set of data. To do this you must first order the data from least to greatest:
3.44, 5.0, 6.09, 8.74
Now on each "level" remove the largest and the smallest number until you get to the middle number(s)
3.44, 5.0, 6.09, 8.74
5.0, 6.09
Since there isn't exactly one number in the middle you must take the mean (average) of the two numbers left. To do this you must add the remaining numbers, 5.0 and 6.09, together then divide by 2
5.0 + 6.09 = 11.09
11.09 ÷ 2 = 5.545
The mean of this data set is 5.545

The conditional probability that a dessert contains nuts given that it contains chocolate is approximately 30.7%, calculated by dividing the probability of both events occurring by the probability of the condition (chocolate presence).
The student is asking for the conditional probability that a dessert contains nuts given that it contains chocolate. Since we are given that the probability a dessert contains chocolate (P(C)) is 75%, and the probability that a dessert contains both chocolate and nuts (P(C AND N)) is 23%, we can find the conditional probability (P(N|C)) by dividing the probability of the joint event by the probability of the condition:
P(N|C) = P(C AND N) / P(C)
P(N|C) = 0.23 / 0.75
P(N|C) = 0.3067
Therefore, the probability that a dessert chosen at random contains nuts given that it contains chocolate is about 30.7% when rounded to the nearest tenth of a percent.
Which equation represents the graphed function?
Answer:
y = -2x + 3
Step-by-step explanation:
The three is the y-intercept, so when x=0, y will equal 3. (0,3)
The slope is negative (-2x), because the minus is present infront of x. So the line's going down.
And we can confirm that it's the function
y = -2x + 3 by letting one point in the line from the graph enter the function.
For example (1,1)
1 = -2x + 3. (let y = 1.)
1 = -2(1) + 3 (let x = 1)
1 = 1
so we can see when we let 1 = -2(1) + 3 it equals the y value on the line.
Answer:
Step-by-step explanation:
y= -2x + 3

What is the largest possible three-digit result
that can be obtained on the right side of the
equation?
Answer:
532
Step-by-step explanation:
To make the right hand side as large as possible, the numerator must be as large as possible and the denominator must be as small as possible. But we can only use each digit once.
Through trial and error:
(9 × 8 + 4) / (1 − 6 ÷ 7) = 532
532 is the largest possible three digit that can be obtained on the right side of equation.
What is PEMDAS?
PEMDAS is short form of parentheses, exponents, multiplication , division, addition and subtraction.
To get the the largest possible three digit from given condition, we have to make the denominator as small as possible by using subtraction and division. And we can increase the numerator.
Now, through trial and error method
we have (9 * 8 + 4) / ( 1 - 6 / 7 ) = 76 * 7 = 532
Hence 532 is the largest possible three digit that can be obtained on the right side of equation.
