Answer:
f(x)=5⋅2.5^x
Step-by-step explanation:
Simple really, all you have to do is plug it in.
5·2.5 ^(-1)
Once you plug it in, solve it! This part you can do on a calculator, or you could always solve it out.
The answer is 2. So that one was correct because 5⋅2.5^(-1) = 2 like the graph says, -1x = 2y. You still have to make sure that it is correct all the way through. So, just plug in the x value in the (x) spot.
The x values are:
-1, 0, 1, 2, and 3
The y values (which are the answers) are:
2, 5, 12.5, 31.25, and 78.125.
Every time you plug in the numbers, make sure you place them in the right spot. For instance, 5⋅2.5^x is the equation; all you have to do is put the x values in the x spot to get the answer.
The next value 5⋅2.5^(0) equals to 5. If the answers come out the same as the graph; it means its correct.
The other answers are NOT correct because the answer is not the same as the y values.
I want to make this as simple as possible so let me break it down. F(x) is just telling you to plug the equation in. The graph is telling you what numbers to plug in and what the answer should be. The x value is going to be the number you plug in. You just need to put it in the (x) spot (where ever it says (x) that's where you need to plug it in.) The y value is what your answer should be, if it is not your answer, that means it's not correct. An easy way to get the answers is by going through the answer choses and plugging them in as that. So what I did was take the equation f(x)=5⋅2.5^x and plug it in as that. Yes, I did go through all the other ones like f(x)= 2.5^x, but it was way easier to do. Just make sure you check through them all, so you don't mess up.
The equation that represents the table will be y = 5(2.5)ˣ. Then the correct option is C.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as,
y = a(b)ˣ
At x = 0, the value of 'y' is 5. Then we have
5 = a(b)⁰
a = 5
At x = 1, the value of 'y' is 12.5. Then we have
12.5 = 5(b)¹
b = 12.5 / 5
b = 2.5
Thus, the equation that represents the table will be y = 5(2.5)ˣ. Then the correct option is C.

In the past, 35% of the students at ABC University were in the Business College, 35% of the students were in the Liberal Arts College, and 30% of the students were in the Education College. To see whether or not the proportions have changed, a sample of 300 students was taken. Ninety of the sample students are in the Business College, 120 are in the Liberal Arts College, and 90 are in the Education College. The calculated value for the test statistic equals
Answer:
The test statistic for Business College is -0.9944
The test statistic for Liberal Arts College is 1.1483
The test statistic for Education College is 0
Step-by-step explanation:
The percentage of ABC University college students in
Business College = 35%
Liberal Arts College = 35%
Education College = 30%
The number of students in the sample = 300 students
In the sample, the number of students in;
Business College = 90
Liberal Arts College = 120
Education College = 90
Therefore;
The percentage of Business College students = 90/300 × 100 = 30%
The percentage of Liberal Arts College, = 120/300 × 100 = 40%
The percentage of Education College, [tex]\hat p[/tex] = 90/300 × 100 = 30%
The test statistic for the difference in two proportions is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p \cdot q}{n}}}[/tex]
Where;
[tex]\hat p[/tex] = The sample proportion
p = The population proportion
q = 1 - p
n = The sample size
The test statistic for Business College is;
[tex]z=\dfrac{0.3-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{90}}} \approx -0.9944[/tex]
The test statistic for Liberal Arts College is;
[tex]z=\dfrac{0.4-0.35}{\sqrt{\dfrac{0.35 \times 0.65}{120}}} \approx 1.1483[/tex]
The test statistic for Education College is;
[tex]z=\dfrac{0.3-0.3}{\sqrt{\dfrac{0.3 \times 0.70}{120}}} \approx 0[/tex]
Answer:
Using the Chi-Square test we find test statistic equals 4.29
Step-by-step explanation:
Start by calculating the expected value:
35% Business College = 0.35 x 300 = 105
35% Liberal Arts College = 0.35 x 300 = 105
30% Education College = 0.3 x 300 = 90

Step-by-step explanation:
It is C because if you multiply each number on the left by 250 and then add 500, you will get the number on the right.
4 x 250 = 1000 + 500 = 1500
8 x 250 = 2000 + 500 = 2500
10 x 250 = 2500 + 500 = 3000

A) X = 5, y = 15
B) x = 15, y = 5
C) x = 30, y = 60
D) x = 60, y = 30
Answer:
A) X = 5, y = 15
Step-by-step explanation:
De la figura:
∠EHD = ∠EGB (los ángulos correspondientes son iguales). Por lo tanto;
18x-2y = 60 (1)
Además, ∠CHF = ∠EHD (los ángulos opuestos serticales son iguales). Por eso;
18x-2y = 9x + y
18x-9x-2y-y = 0
9x-3y = 0 (2)
Para resolver x e y, resolvemos la ecuación (1) y (2) simultáneamente.
Multiplique la ecuación (2) por 2 y reste de la ecuación (1):
4 años = 60
y = 15
Pon y = 15 en la ecuación (2):
9x-3 (15) = 0
9x-45 = 0
9x = 45
x = 5

A. x=5
B. x=0
C. x=3
D. x=2
Answer:
x = 2
Step-by-step explanation:
Substitute x = 2 into y = 5x² , that is
y = 5(2)² = 5(4) = 20 ≠ 10
Thus (x, y ) = (2, 20 ) and not (2, 10 )

Answer:
new = 1/3 old = 1/2
new - old = 1/3 - 1/2 = 2/6 - 3/6 = -1/6
dividing by the old: -1/6 divided by 1/2 = -1/6 * 2/1 = -1/3

After you write it out & cancel, what will be "leftover" in the numerator? EXPLAIN HOW YOU KNOW.
x⁴y³
________
x³y⁴
Answer:
x
Step-by-step explanation:
When writing out an canceling variable/exponents within a fraction, you always subtract the top and bottom. So...
[tex]\frac{x^{4}y^{3}}{x^{3}y^{4}}[/tex]
When you subtract, you always put the leftover variable in the spot that had the highest valued exponent.
So the equation simplifies to [tex]\frac{x}{y}[/tex]
x, is on top so it is the numerator.
