Answer: Any positive number less than 16
The diagram shows AD = 16. Applying a dilation with positive scale factor less than 1, will make the figure shrink. Segment AD becomes smaller, so the new AD will be some length less than 16.
For instance, if you use a scale factor 1/2 = 0.5, then AD = 16 turns into A'D' = 16*0.5 = 8

Permutations vs combinations(one step):
The bowling team at Lincoln High School must choose a president, vice
president, and secretary. If the team has 15 members, which expression could
be used to determine the number of ways the officers could be chosen?
Answer:
the expression is: [tex]^{15}P_3=\frac{15!}{(15-3)!}[/tex]
and 2730 different ways are possible.
Step-by-step explanation:
In the given question we have to choose a president, vice
president, and secretary.
Permutations are used when order is important so, as in the given question order is required. We would use permutations
The formula used is: [tex]^nP_r=\frac{n!}{(n-r)!}[/tex] where:
n=total number of objects
r=number of objects selected
In our case: n=15, r=3
Putting values and finding the answer:
[tex]^nP_r\\^{15}P_3=\frac{15!}{(15-3)!} =2730 \ ways[/tex]
So, the expression is: [tex]^{15}P_3=\frac{15!}{(15-3)!}[/tex]
and 2730 different ways are possible.
The high for a winter day in Sitka,
AK was 10 degrees below zero. The
low for the same day was 25
degrees below zero. What was the
range of temperatures for the day?
Answer:
The maximum temperature will be -10°C, then if T represents the temperature, we can write this as:
T ≤ -10°C
And the minimum temperature will be -25°C, then we must have that:
T ≥ -25°C
if we use both conditions, we will have:
-25°C ≤ T ≤ -10°C
We can write this range:
[-25°C, -10°C]
Where the [] symbols mean that the extremes are possible temperatures.
The length of the range will be:
-10°C - 25°C = 15°C.

The balance on a checking account is -$15. Interpret the direction and magnitude of this value.
A.The owner of the checking account is owed -$15.
B.The owner of the checking account is owed $15.
C. The checking account is overdrawn by -$15.
D.The checking account is overdrawn by $15.
Answer:
D. The checking account is overdrawn by $15.
Step-by-step explanation:
Since the balance on a checking account represents the remaining money left in that checking account, having a negative value for that would mean an overdrawing of money, or drawing more money than is in that account in the first place.
Therefore, the answer would be that the checking account is overdrawn by $15.

In order to set premiums at profitable levels, insurance companies must estimate how much they will have to pay in claims on cars of each make and model, based on the value of the car and how much damage it sustains in accidents. Let C be a random variable that represents the cost of a randomly selected car of one model to the insurance company. The probability distribution of C is given below. The probability that the insurance company will have to pay a claim of at least $1000 for a randomly selected car is:
Answer:
The answer is "0.35"
Step-by-step explanation:
Please find the complete question in the attached file.
In the given table the distributions of probabilities provided is a continuous spread for both the random variable c.
They need to have a cumulative chance of receiving claims of 4000 or higher to determine the probability of an insurance company ending let's give claims of at least 4000.
So, The right equation for the answer will then be [tex]0.13 + 0.22=0.35[/tex]
Ravi wants to buy a new guitar that costs $129.99. He has $27, and decides to give music lessons to earn the rest of the money. Ravi decides to charge $22 per lesson. Which inequality would best help Ravi find m, the number of lessons he would need to give in order to buy the guitar?
A. 22m + 27 129.99
The inequality that would help Ravi the best to find m, the number of lessons he would need to give in order to buy the guitar will be 27 + 22 m ≥ 129.99.
Cost of guitar that Ravi wants to buy = $ 129.99
The amount of money that he has = $27
The amount of money that he will get per lesson = $ 22
Let the number of lessons given by Ravi be m.
Now, we know that he has to earn $ 129.99 or more to purchase the guitar.
So, the inequality will become:
27 + 22 m ≥ 129.99
Therefore, we get that, the inequality that would help Ravi the best to find m, the number of lessons he would need to give in order to buy the guitar will be 27 + 22 m ≥ 129.99.

Mia buys 50 coats at $28 each she sells 38 of these coats at$49 each she sells the rest of the coats at$40 each find the overall percentage profit mia has made on these coats
Answer:
67.28 %
Step-by-step explanation:
Given that:
Price at which the coats are bought = $28
Number of coats bought = 50
Total money spent on buying the coats = 50 [tex]\times[/tex] 28 = $1400
Number of coats sold at $49 each = 38
Money earned by selling 38 coats at $49 each = $1862
Number of coats left = 50 - 38 = 12
Money earned by selling 12 coats at $40 each = $480
Total money earned = $1862 + $480 = $2342
To find:
The overall profit percentage made by Mia ?
Solution:
Formula for Profit percentage:
[tex]Profit\% = \dfrac{Sales\ Price - Cost\ Price}{Cost\ Price}\times 100\\\Rightarrow Profit\% = \dfrac{2342 - 1400}{1400}\times 100\\\Rightarrow Profit\%=\dfrac{942}{1400}\times 100\\\Rightarrow Profit\%=67.28\%[/tex]
Therefore, overall percentage profit made by Mia by selling the coats= 67.28 %
The graph of f (x) = x + 5 is a vertical translation 5 units
up of the graph of f(x) = x. How can you obtain the graph of
f(x) = x + 5 from the graph of f (x) = x using a horizontal
translation?
Answer:
A horizontal translation of 5 units to the left.
Step-by-step explanation:
Given the parent linear function:
[tex]\displaystyle f(x)=x[/tex]
To shift vertically n units, we can simply add n to our function. Hence:
[tex]f(x)=x+n[/tex]
So, a vertical shift of 5 units up implies that n=5. So:
[tex]f(x)=x+5[/tex]
As given.
However, to shift a linear function horizontally, we substitute our x for (x-n), where n is the horizontal shift. So:
[tex]f(x-n)=(x-n)[/tex]
Where n is the horizontal shift.
For example, if we shift our parent linear function 1 unit to the right, this means that n=1. Therefore, our new function will be:
[tex]f(x-1)=(x-1)[/tex]
Or:
[tex]f(x)=x-1[/tex]
We notice that this is also a vertical shift of 1 unit downwards.
Therefore, we want a number n such that -n=5.
So, n=-5.
Therefore, it we shift our function 5 units to the left, then n=-5.
Then, our function will be:
[tex]f(x-(-5))=(x+5)\text{ or } f(x)=x+5[/tex]
Hence, we can achieve f(x)=x+5 from f(x)=x using a horizontal translation by translating our function 5 units to the left.
Solve by using elimination. Express your answer as an ordered pair.
Answer:
(-2, 5)
Step-by-step explanation:
we subtract 6x+3y=3 by 2x+3y=11 to get 4x=-8.
we divide both sides by 4 to get x. x=-2
We subsitute -2 for the second equation to get:
2(-2)+3y=11
=-4+3y=11
=3y=15
y=5
Greetings again.
The answer is (-2,5)
Explanation:
What we need to do is to eliminate either x-term or y-term. Eliminating the terms that you don't have to multiply to get the same terms for both equations is better.
For this one, there're no terms that make 0.
And what do we do if there are no terms that can be eliminated?
The answer is, multiply one of the equation by -1. To make another equation have opposite negative and positive side. -3y + 3y = 0.
I'll multiply -1 in the second equation.
[tex]2x+3y=11[/tex]
Multiply the whole equation by -1.
[tex]2x(-1)+3y(-1)=11(-1)\\-2x-3y=-11[/tex]
Remind that negative multiply positive equal negative.
Now then we replace the old equation with -2x - 3y = -11
[tex]\left \{ {{6x+3y=3} \atop {-2x-3y=-11}} \right.[/tex]
Then add/subtract vertically.
6x-2x = 4x
3y - 3y = 0
3 - 11 = -8
Therefore, we get 4x = -8
[tex]4x=-8\\x=-2[/tex]
Because this is the system of two linear equations. We need to find the y-term/value too.
Substitute x = -2 in any given equations. choose any equations you'd like to substitute in. For me, I'll substitute in the equation with less coefficient value and that is the second equation.
[tex]2x+3y=11[/tex]
Substitute x = -2 in the equation.
[tex]2(-2)+3y=11\\-4+3y=11\\3y=11+4\\3y=15\\y=5[/tex]
Thus, when x = -2, y = 5. Since you want the answer as an ordered pairs. The answer is (-2,5)
