state the solutions for the quadratic equation depicted in the graph.
Answer:
(-4,0), (-3,0)
Step-by-step explanation:
The solution of a quadratic equation is simply when the graph crosses the x-axis. This is because at that point, the function will equal 0.
From the graph, we can see that the graph touches the x-axis at x=-4 and x=-3.
Therefore, our solutions for the graphed quadratic is x=-4 and x=-3.
And we're done!

4.5 and 5 are respectively the average of 2sets of number 3, 4, x, y and 2x, y, 4, 3, find the value of x, y
Step-by-step explanation:
4.5 * 4 = 18.
3 + 4 + x + y = 18, x + y = 11.
5 * 4 = 20
2x + y + 4 + 3 = 20, 2x + y = 13
Hence, x = 2 and y = 9.
Examples: Determine if the graph is a function. If it is, state the domain and range.
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.Jan 8, 2019
Step-by-step explanation:
Look at the graph. On a coordinate plane, a graph increases through (negative 1, 4), levels off at (0, negative 3), and then increases up through (2, 5). Leslie analyzed the graph to determine if the function it represents is linear or non-linear. First she found three points on the graph to be (–1, –4), (0, -3), and (2, 5). Next, she determined the rate of change between the points (–1, –4) and (0, -3) to be StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction = StartFraction 1 Over 1 EndFraction = 1. and the rate of change between the points (0, -3) and (2, 5) to be StartFraction 5 minus (negative 3) Over 2 minus 0 EndFraction = StartFraction 8 Over 2 EndFraction = 4. Finally, she concluded that since the rate of change is not constant, the function must be linear. Why is Leslie wrong? The points (–1, –4), (0, –3), and (2, 5) are not all on the graph. The expressions StartFraction negative 3 minus (negative 4) Over 0 minus (negative 1) EndFraction and StartFraction negative 3 minus (negative 5) Over 2 minus 0 EndFraction both equal 1. She miscalculated the rates of change. Her conclusion is wrong. If the rate of change is not constant, then the function cannot be linear.

An explorer is climbing up and rappelling down a series of cliffs and drop-offs. She starts at her base camp, which is on the middle of a mountain. She begins by rappelling down an 82.5-foot drop-off and then climbs a cliff of 30.4 feet. Next she rappels down a 45.5-foot drop-off and then climbs a 25.2-foot cliff.Finally she makes two 45.4-foot climbs. Part A: How far above or below her base camp is the explorer now?
Answer:
162.8 above her camp site she starts at the middle and drops 82.5 and then climbs 30.4 which puts her at 52.1 then by her repelling down another 45.5 drop she then proceeds to climb 25.2 which puts her at 72.4 and if you multiplie 45.4 by 2 it counts for the extra 90.4 drop which then concludes her climb to be bellow her site by 162.8 and the 1st word is supposed to be bellow my bad.

Which of the following is an example of stratified sampling when obtaining a sample of 100 high school students? A. Choosing 100 students at random from a specific grade level at a high school.B. Choosing 100 students sitting in one random section of the cafeteria at a high school.C. Choosing 25 students at random from each of four different grade levels at a high school.D. Choosing 100 students at random from a high school. E. Choosing 100 students at random from an AP Statistics class at a high school.
Answer:
Option C - Choosing 25 students at random from each of four different grade levels at a high school
Step-by-step explanation:
For us to achieve the conditions for a stratified random sample, the target population must be split into different groups which in this case, it's grade levels.
Looking at the 5 options given in the question, Options A, B, D and E are random but they are not truly stratified in their sampling approach. This is because the sample population must be selected at random from each of these groups and it's only option C which is choosing 25 students from each of four different grade levels or groups that reflects that.

The toy horse collection contains 10 horses. You purchase the set and then sell 3 horses to Kate. If you only charge the exact price (no tax involved), how much does Kate pay you?
Answer:
three tenths of the original amount
Let's start.
There are 10 horses.
(Buying the set is not important, since it does not affect this scenario.)
You sell three horses to Kate, and you expect her to give you the exact price.
Let's say that 10 horses cost the total (unknown).
10 horses equal the total amount, or 1
10 to 1
Now, you sell 3 of these horses. You must multiply 10 and n to make 3.
10 x n = 3
10x 3/10 = 3
Do the same to the other side.
1 x 3/10 = 3/10

How do you do letter b?
Answer: 175
Step-by-step explanation:
[tex]g(35)= \int\limits^{35}_0 {f(x)} \, dx =\int\limits^{30}_0 {f(x)} \, dx +\int\limits^{35}_{30} {f(x)} \, dx[/tex]
= 137.5 + 37.5
= 175
Answer:
g(35) = 137.5
Step-by-step explanation:
g(35) = g(30) + [g(35) - g(30)]
g(35) = 100 + 5(15)/2
g(35) = 137.5
Given the function k(t)=2t−1: a. Evaluate k(2). b. Solve(k)=7.
Answer:
[tex]k(2) = 3[/tex]
[tex]t = 4[/tex]
Step-by-step explanation:
Given
[tex]k(t) = 2t - 1[/tex]
Solving (1): k(2)
Take t as 2 such that t = 2
This gives
[tex]k(2) = 2 * 2 - 1[/tex]
[tex]k(2) = 4 - 1[/tex]
[tex]k(2) = 3[/tex]
Solving (2): k(t) = 7
Substitute 7 for k(t)
[tex]7 = 2t - 1[/tex]
Add 1 to both sides
[tex]7 + 1 = 2t - 1 + 1[/tex]
[tex]2t = 8[/tex]
Divide both sides by 2
[tex]t = \frac{8}{2}[/tex]
[tex]t = 4[/tex]
1.6=Y/1.5 WHAT IS THE ANSWER
Isolate the variable Y by multiplying 1.5 on both sides.

[tex]Y=2.4[/tex]
Hope this helps.
頑張って!
Answer:
y=2.4
Step-by-step explanation:
You need to get Y alone so just multiply it with the reciprocal: 1.5/1 on both sides. This cancells out the denominator and just multiplies 1.6 with 1.5 to get 2.4

What is absolute value ?
Answer:
the magnitude of a real number without regard to its sign.
Step-by-step explanation:
Solving Absolute Value is just asking you how far away -4 is from zero. Since distance is always a positive number (you can't travel "negative" steps, just steps in a different direction), the result of absolute value is always positive. Make the number in the absolute value sign positive.
Ten people ordered calculators. The least expensive was $29.95 and the most expensive was $89.95. Half of them ordered a $69.95 calculator. Select the best
estimate of the amount spent on calculators.

Choose the best estimate for the total amount spent for all 10 calculators.
O A. $805
OB. $490
OC. $550
OD. $660
Answer:
310
Step-by-step explanation:
least money 19.95
Most money = 39.95
Mean = (least+most)/2 = 29.95
money for half people = 5 × (mean) 29.95
Amount of money for half people = 149.75
Lower limit for amount of the other half = 19.95 × 5 = 99.75
The Upper limit for the amount of the other half = 39.95 × 5 = 199.75
Mean = (99.75 + 199.75)/2 = 149.75
Total money spent (Mean) = 149.75 + 149.75 = 299.5
The Best estimate is B) 310 because it is closest to 295.5
A mean is an arithmetic average of a set of observations. The correct option is D.
What is Mean?A mean is an arithmetic average of a set of observations. It is given by the formula,
Mean = (Sum of observations)/Number of observations
To make the calculations easy let's round off the given numbers. Therefore, we can write the values as,
Least expensive A=30Most expensive B=90half of order C=70Now, the mean and the money for half the people can be written as,
Mean = (least + most)/2 = 60
money for half people = 5 × 60
Therefore, the amount of money for half people will be,
Amount of money for half people = 300
Lower limit for amount of the other half = 29.95 × 5 = 149.5
The Upper limit for the amount of the other half = 89.95 × 5 = 449.75
Mean = (149.75 + 449.75)/2 = 299.6
Total money spent (Mean) = 299.6 + 299.6 = 599.25
Hence, The Best estimate is $660. This is because it is closest to 599.25.

A media personality argues that global temperatures are not rising, because every year an increase is reported such as 0.08 degrees C. The difference from the previous year is less than the margin of error of about 0.15 degrees C, so that difference should be ignored. What is a strong counterargument?
Answer
:we are told that every year the temperature rises by 0.08degrees Centigrade,
So the difference between margin of error and the increase is much higher
That is
0.15-0.08=0.07
But remember Margin of error=Critical value *Standard deviation of population
And it is a quantity that measures accuracy
So the counter argument is that this is still an increase and it should be considered.
.
Answer:
The difference with any previous decade is much greater than the margin of error

Circle B is shown. Line segments C B, D B, and E B are radii and they form 3 congruent angles. What does Arc C D E describe? a minor arc a major arc a semicircle a chord
Answer:
a major arc
Step-by-step explanation:
A circle is the locus of point in which has a given distance from a fixed point (center of the circle).
B is the center of the circle C B, D B, and E B are radii forming 3 congruent angle. Since the sum of angles in a circle is 360°, the 3 line segments form 3 congruent angles of 120° each (360/3).
Therefore the angle measure of Arc C D E = Arc CD + Arc DE = 120° + 120° = 240°
A major arc is an arc greater than a semicircle (> 180°). This means that Arc C D E is a major arc
