Using proportions, they must win 22 games to maintain to the ratio of wins to losses.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Considering the next 28 games, we have that:
The team will have won 33 + x games.The team will have played 42 + 28 = 70 games.To keep the same proportion, we have that:
[tex]\frac{33}{42} = \frac{33 + x}{70}[/tex]
Applying cross multiplication:
42(33 + x) = 33 x 70
Simplifying by 14:
3(33 + x) = 33 x 5
3x = 33 x 5 - 33 x 3
3x = 33 x 2
3x = 66
x = 66/3
x = 22.

A. P-value
B. power of the test
C. Type Il error
D. significance level
Option D is the correct answer. The probability that a test correctly rejects a false null hypothesis is called the significance level.
The significance level, also known as alpha or α, is a measure of the strength of the evidence that must be present in your sample before you will reject the null hypothesis and conclude that the effect is statistically significant.
The probability of making a type II error (failing to reject the null hypothesis when it is actually false) is called β (beta). The quantity (1 - β) is called power, the significance level is the probability of rejecting the null hypothesis when it is true.
For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. Lower significance levels indicate that you require stronger evidence before you will reject the null hypothesis.

Answer:
1. Growth
2. Decay
3. Decay
Step-by-step explanation:
Growth means as x increases, y increases too. On the other hand, decay means as x increases, y decreases. There's the theory for exponential function regarding this growth and decay.
Growth
If the base is not a decimal or a fraction then it's growth.
Decay
If the base is a decimal or a fraction then it's decay.
From the problem, first function has base of 5. Hence, it's growth. On the other hand, second and third function both have decimal and fraction as the base. Hence, it's decay.
When considering growth or decay graph, we can ignore the coefficient since it doesn't determine the growth and decay. The only thing that determines if a function increases or decreases is the base under the exponent.

A homeowner is financing the cost of new windows. Two lenders have approved the homeowner for a $12,000 loan. The terms of each loan are:
Offer 1: 4.5% annual simple interest, with a total account balance of $14,430 after a 54-month term
Offer 2: 3.75% annual interest compounded monthly for a 66-month term
Assuming no payments are made, what is the difference in the account balances at the end of the loan terms. Round your answer to the nearest penny.
$204.88
$313.98
$767.12
$795.34
Answer:
$313.98
Step-by-step explanation:
[tex]Equation: A=P(1+\frac{r}{n} )^{nt} \\\\A=12000(1+\frac{0.0375}{12} )^{12(5.5)} \\\\A=12000(1+0.003125)^{66} \\\\A=12000(1.003125)^{66}\\\\A=12000(1.228665)\\\\A=14743.98\\[/tex]
So to see the difference of account balances we would subtract offer 1 balance from offer 2 balance.
14743.98-14430 = 313.98
So, therefore the difference in the account balances at the end of the loan terms is $313.98.
Note: the 5.5 comes from converting 66 months to years which is 5.5
Line m represents a translation of line L3 units down and 2 units left. Which equation represents line L?
The linear equation L, which is a translation of line M, can be written as:
y = (2/3)*x - 2
So the correct option is the last one.
How to find the equation of line L?
First, we need to find the equation of line M.
Remember that the general linear equation is:
y = a*x + b
Where a is the slope and b is the y-intercept.
On the graph we can see that the y-intercept is y = -2, then we wll get:
y = a*x - 2
And we can also see that the line passes through (-3, -4)
Replacing these values we will get:
-4 = a*-3 - 2
-4 + 2 = -3a
-2/-3 = a
2/3 = a
So line M is:
y = (2/3)*x - 2
And line M is a translation of 3 units down and 2 units left of L, then L is a translation of 3 units up and 2 units to the right, then we can write line L as:
y = (2/3)*(x - 2) - 2 + 3
y = (2/3)*x + (2/3)*-2 - 2 + 3
y = (2/3)*x - 4/3 + 1
y = (2/3)*x - 1/3
So the correct option is the last one.

The limit of cos(t) and [tex]t^3[/tex] ln(t) is zero as t approaches zero from the right. However, the limit of cos(t) as t approaches zero from the right is not defined. This is because the cosine function oscillates between -1 and 1 as t approaches zero, and therefore it does not approach a specific value.

A loan of $25,000 has an annual simple interest rate of 5.5%. The total cost of the loan is $38,750.
B. How long does it take to repay the loan?
===========================================
Work Shown:
A = final value = 38750
P = amount loaned = 25000
i = interest
i = A - P = 38750 - 25000 = 13750
Now apply the simple interest formula to solve for t.
i = P*r*t
13750 = 25000*0.055*t
13750 = 1375*t
t = 13750/1375
t = 10 years to pay off the loan

Find the mean of the three numbers at the right 2 1/3 3 2/3 5 1/4
Answer:
To find the mean (average) of a set of numbers, we add them together and divide by the number of items in the set.
The first step is to convert all the fractions into a common denominator. In this case, the least common multiple of 3, 3, and 4 is 12.
2 1/3 = 7/3
3 2/3 = 11/3
5 1/4 = 21/4
Now we can add these numbers together:
7/3 + 11/3 + 21/4 = (7 + 11 + 21) / 3 = 39/3 = 13
There are three numbers, so we divide by 3.

Answer:

Step-by-step explanation:
(1) In all parallelograms, the diagonals bisect each other, or split each other into two congruent (same) halves.
We are given parallelogram HJKL. Its diagonals are HK and JL, because they both are segments that connect two opposite vertexes.
This means that HK and JL are bisected.
Thus, HM is half of HK.
Let's make an equation to represent this situation and solve for HK.
[tex]HM = \frac{1}{2}HK[/tex]
⇒ [tex]12 = \frac{1}{2}HK[/tex] . . . . . . substitute known values
⇒ [tex]12(2) = \frac{1}{2}HK(2)[/tex] . . . . . . multiply the LHS and RHS by 2 to isolate HK
⇒ ∴ [tex]24 = HK[/tex] . . . . . . compute
(2) This problem is similar to #1, so we can use the same concepts as #1.
However, we are given an expression instead of integers.
The only thing that's different about this problem is that we need to solve for x, not a diagonal or part of a diagonal.
VX and UW are the diagonals of parallelogram UVWX.
Thus, VX and UW are bisected.
Thus, the VY and YX are the same length, because they are split in half.
Let's make an equation to represent this situation and solve for x.
[tex]VY = YX[/tex]
⇒ [tex]80 = 6x + 2[/tex] . . . . . . substitute the known values
⇒ [tex]78 = 6x[/tex] . . . . . . . . . subtract 2 from the LHS and RHS
⇒ ∴[tex]13 = x[/tex] . . . . . . . . . divide both sides by 6 to isolate x
(3) This problem uses the exact same concepts and steps as #2.
Thus, RS and SP are the same length.
Let's make an equation to represent this situation and solve for x.
[tex]RS = SP[/tex]
⇒ [tex]65 = -2x - 7[/tex] . . . . . . . . substitute the known values
⇒ [tex]72 = -2x[/tex] . . . . . . . . . . . add 7 to the LHS and RHS
⇒ ∴[tex]-36 = x[/tex] . . . . . . . . . . . divide both sides by -2 to isolate x
(4) In a parallelogram, the opposite angles are congruent (the same).
In parallelogram ABCD, we are given ∠CDA and asked to solve for ∠ABC.
∠ABC and ∠CDA are opposite angles.
∠CDA = 120°
∠ABC = ∠CDA
∴ ∠ABC = 120°

The parallelogram HJKL is handed to us. The segments HK and JL, which both link two vertexes that are in opposition to one another, serve as its diagonals, triangle HK = 24; x = 13; x = -26; ∠ABC = 120°
What is triangle?A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric shapes. The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.
All parallelograms have diagonals that cut them in half or divide them into two congruent (same) halves.
HK = 24, x = 13, x = -26, and ABC = 120 degrees.
The parallelogram HJKL is handed to us. The segments HK and JL, which both link two vertexes that are in opposition to one another, serve as its diagonals.
As a result, HK and JL are divided. HM therefore makes up half of HK.
