Answer:
-3.3125[tex]\frac{-10.125-(-3.5)}{4-2} =\frac{-6.625}{2} = -3.3125[/tex]
Step-by-step explanation:
Average rate of change is the slope between two points.
Slope getween points [tex]\left(x_1,\,y_1\right)[/tex] and [tex]\left(x_2,\,y_2\right)[/tex] is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

Answers
Answer:
[tex](a)\ t = -2.146[/tex]
The null hypothesis is rejected
[tex](b)\ t = 2.014[/tex]
The null hypothesis is accepted
[tex](c)\ t = 2.128[/tex]
The null hypothesis is accepted
[tex](d)\ t = -2.146[/tex]
The null hypothesis is rejected
Step-by-step explanation:
Given
[Missing from the question]
[tex]\alpha = -1.001[/tex] --- critical value
Left tailed test
Required
State what the standardized test statistics indicates
Since it is a left-tailed test, the null hypothesis will be rejected if the standardized test statistics less than or equal to the critical value
Using the above rule, we have:
[tex](a)\ t = -2.146[/tex]
Compare t and [tex]\alpha[/tex]
[tex]-2.146 < -1.001[/tex]
The null hypothesis is rejected
[tex](b)\ t = 2.014[/tex]
Compare t and [tex]\alpha[/tex]
[tex]2.014> -1.001[/tex]
The null hypothesis is accepted
[tex](c)\ t = 2.128[/tex]
Compare t and [tex]\alpha[/tex]
[tex]2.128> -1.001[/tex]
The null hypothesis is accepted
[tex](d)\ t = -2.146[/tex]
Compare t and [tex]\alpha[/tex]
[tex]-2.146 < -1.001[/tex]
The null hypothesis is rejected
Mr.russo exchanged 200 euros for 270 dollars how many dollar he get foe 300 euros
Answers
Now we multiply 300 by 1.35 to get 405 dollars
Answer:
$405
Step-by-step explanation:
This is a proportion problem!
Build fractions that have euros on top and dollars on the bottom (or the other way around, you decide, but make it the same in both fractions).
Let's do euros over dollars.
Setup:
[tex]\frac{200}{270}=\frac{300}{d}[/tex]
"Cross multiply."
[tex]200d=300\times 270\\\\200d=81000\\\\d=\frac{81000}{200}=405[/tex]

Find the Pattern If the pattern continued, how many orange blocks would be in the next figure? Can you write a linear function (y = mx + b) that gives the number of blocks for any figure?
Answers
Answer:
Part A
aₙ = 5 + (n - 1)·4
Part B
y = 4·x + 1
Step-by-step explanation:
Part A
The number of orange blocks in Figure 1 = 5
The number of orange blocks in Figure 2 = 9
The number of orange blocks in Figure 3 = 13
Therefore, we get;
5, 9, 13, ... with increments of 4
The first term, a = 5
The common difference, d = 4
The sequence is in the form of an Arithmetic Progression, therefore, we have;
aₙ = 5 + (n - 1)·4
Where;
n = The Figure number
When n = 3, we have;
a₃ = 5 + (3 - 1) × 4 = 12 orange blocks as in the diagram in the question
Part B
To express the number of blocks using the linear function, y = m·x + b, we have;
Let 'x', represent the number of each figure, let 'y' represent the total number of blocks in each figure, let 'd' represent the initial amount of blocks present when x = 0, and let 'm' represent the rate of change of 'y' with each change in 'x'
We note that the rate of change the total number of blocks for each increase in figure number is 4, therefore, we have;
The rate of change, m = 4
∴ y = 4·x + d
When x = 1, y = 5, we get;
5 = 4 × 1 + d
∴ d = 5 - 4 = 1
d = 1
The linear equation that gives the number of blocks is therefore;
y = 4·x + 1.

Answer:
a) I donot agree with him because as we see the sequence nicely we will find an interval of 8 between any two terms and 32 and 33 don't match them
Step-by-step explanation:
b) and c) Solution:
Given,
First term (a) = 4
Common difference (d) = 12-4 = 8
Now,
Since, they are in A.P.
nth term = a + (n-1)d
= 4 + 8(n-1)
= 4 + 8n-8
= 8n-4
Again,
1st method for c)
100th term = a + 99d = 4 + 99*8 = 4 + 792 = 796
200th term = a + 199d = 4 + 199*8 = 4 + 1592 = 1596
2nd method for c)
100th term = 8*100 - 4 = 800 - 4 = 796
200th term = 8*200 - 4 = 1600 - 4 = 1596

y = 45x + 15
Step-by-step explanation:
Given :
Days Total Cost
(d) (C)
2. $105
4 $195
6 $285
10 $465
The daily rate is the slope :
Slope = Rise / Run
Slope = (y2 - y1) / (x2 - x1)
Slope = (465 - 105) / (10 - 2)
Slope = 360 / 8
Slope = 45
Daily rate = $45
Using the slope intercept relation :
y = mx + c
m = slope, c = intercept
105 = 45x + c
105 = 45(2) + c
105 = 90 + c
105 - 90 = c
15 = c
Pricing plan :
y = 45x + 15
Answer is 45 because if you divide 90/2 it equal 45

Answer:
A = 5 units²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂
d₁ = x + 4 = 1 + 4 = 5
d₂ = 2y - 4 = 2(3) - 4 = 6 - 4 = 2 , then
A = [tex]\frac{1}{2}[/tex] × 5 × 2 = 5 units²
Answer:
A= 5m
Step-by-step explanation:
The equation to find the area of a rhombus, when knowing the diagonals, is:
1/2×d1×d2To solve this, we have to find first d1 and d2, which are marked in a parenthesis:
d1= (x+4)m, where x=1d1= 5md1= 5m. Now, let's find d2:
d2= (2y-4)m, and y=3d2= (6-4)md2= 2mKnowing the values of both diameters, we can solve the equation for the area:
A= 1/2×d1×d2A= 1/2×5m×2mA= 1/2×10mA= 5mThe area of the rhombus is 5 meters.

The sum of 5 times a larger number and twice a smaller is 5. The difference of 4 times the larger and the smaller number is 4. Find the numbers.
Answers
Answer:
1 and 0
Step-by-step explanation:
Let's call the smaller number x and the larger number y.
This means 5y+2x=5.
Also, 4y-x=4.
This is a system of equations. There are two main ways two solve this.
Method 1: Substitution
5y+2x=5
4y-x=4
Solve for one of the variables, then substitute it back into one of the equations to solve for the other variable.
I will take 4y-x=4 and solve for x.
4y=4+x
x=4y-4
Then substitute for x in the other equation and solve for y.
5y+2x=5
5y+2(4y-4)=5
5y+8y-8=5
13y=13
y=1
Now we can go back to our equation for x and substitute for y.
x=4y-4
x=4(1)-4=0
y, the larger number, is 1 and
x, the smaller number, is 0
Method 2: Elimination
5y+2x=5
4y-x=4
Change the equations so that the coefficient of one of the variables in an equation is opposite the one in the other equation. Then add the equations and solve for each variable.
If I multiply both sides of the second equation, 4y-x=4, by 2, the coefficient of x will become -2. In the first equation, the coefficient is 2, so they will become opposites.
4y-x=4
becomes
8y-2x=8
Now we have 5y+2x=5 and 8y-2x=8.
Add the sides of both equations to cancel the x values.
5y+2x+8y-2x=5+8
13y=13
y=1
like last time, we can substitute for y in any of the original equations to get x.
5y+2x=5
5(1)+2x=5
5+2x=5
2x=0
x=0
y, the larger number, is 1 and
x, the smaller number, is 0
