What impact does the 85 have on the mean test score?
Answer:
decrease
Step-by-step explanation:
If 89 is the highest score, Ken would need a score of 90+ to increase the mean.
[tex]Md < 89\\Mi >89[/tex]

If f(x)=3^ x-4 what is f(- 1) ?
Answer:
1/243
Step-by-step explanation:
When you see this notation, it means plug in -1 for x in the function.
f(-1) = 3^((-1)-4)
f(-1) = 3^-5
f(-1) = 1/3^5
f(-1) = 1/243
Step-by-step explanation:

Step-by-step explanation:
Robert purchased a 2010 model sedan for $16,000. The dealership offered
him a $99/month payment for 60 months, after which the unpaid balance is
due. If the interest rate is 6%, find the balloon payment due at the end of 60
months.
O
A. $17,513.12
O
B. $15,000
C. $18,153.21
O
D. $14,674.37
Answer:
The correct option is D. $14,674.37.
Step-by-step explanation:
This can be calculated using the ballon payment formula as follows:
P = (PV - (Ballon / (1 + r)^n)) * (r / (1 – (1 + r)^-n)) ...................... (1)
Where:
P = Monthly payment = $99
PV = present value of the loan or the purchase price of the 2010 model sedan = $16,000
Ballon = Ballon payment due at the end of 60 months = ?
r = monthly interest rate = 6% / 12 = 0.06 / 12 = 0.005
n = number of periods or months = 60
Substituting the values into equation (1) and solve for Ballon, we have:
$99 = ($16,000 - (Ballon / (1 + 0.005)^60)) * (0.005 / (1 -(1 + 0.005)^-60))
$99 = ($16,000 - (Ballon / 1.3488501525493)) * 0.0193328015294284
$99 / 0.0193328015294284 = ($16,000 - (Ballon / 1.3488501525493))
$5,120.83051436193 = $16,000 - (Ballon / 1.3488501525493)
Ballon / 1.3488501525493 = $16,000 - $5,120.83051436193
Ballon / 1.3488501525493 = $10,879.1694856381
Ballon = $10,879.1694856381 * 1.3488501525493
Ballon = $14,674.3694203126
Rounding to 2 decimal places, we have:
Ballon = $14,674.37
Therefore, the correct option is D. $14,674.37.
The population of a town is 15,000. It decreases at a rate of 8% per year. In about how many years
will the population be fewer than 10,000?
Answer:
5
Step-by-step explanation:
If a population is decreasing by 8% we can multiply the population by 92% (1-.08)
which means we have the following equation
population=15000(.92)ⁿ
where n is the number of years
we want to know when the population will be 10,000 so we write
10,000=15,000(.92)ⁿ
.66667=.92ⁿ
a rule we have is
[tex]n=y^x\\log_yn=x[/tex]
which means that
[tex].66667=.92^n\\=log_{.92}.66667[/tex]
compute this and get
4.867
round this up to 5

The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. The distance between Boise, Idaho, and Reno, Nevada, is 430 miles. Express the distance in kilometers.
A.
431.6 km
B.
268.8 km
C.
688 km
Answer:
B
Step-by-step explanation:
Answer:
The answer is C. 688 km
Step-by-step explanation:
you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k
and 665miles x 1.6 = 1064k
1 Mile is 1,6 Kilometers
430 Miles = 688 Kilometers (430 * 1,6)
665 Miles = 1064 Kilometers (665 * 1,6)
1. if you want your questions answered, don't whine -- just ask the question. for example, in this you haven't really asked anyone the question. They have to assume what you are trying to find out.
2. It is simple math if you understand the equation you gave:
You are solving for "k" which is kilometers;
You have been given the distance which is "d" in miles (430 miles and 665 miles)
The equation means: "k" equals 1.6 times the value of "d"
so the answers to your implied questions are:
k = 430 x 1.6 = 688 kilometers
k = 665 x 1.6 = 1064 kilometers
You might also asking your question in a more appropriate category. this is more of a math problem than a geography question (the names of the cities is irrelevant to the answer; the relevant part is the distance in miles).
The number of kilometers is ALWAYS greater than the corresponding miles. For example 1 mile = 1.6 km, so there is no way that when you convert miles to kilometers you will ever come up with a lower number of kilometers than the miles.

Find the y-coordinate of the y-intercept of the polynomial function defined below. f(x)=2(3x+4)(x^2+2)
Answer:
Step-by-step explanation:
The best way to find out the answer to your question is to graph the cubic. As you can see, the y intercept is (0,16).
How was this obtained. notice that if x = 0 then
f(0) = 2(3*0+4)(0^2 + 2)
f(0) = 2(4)(2)
f(0) = 16 just as the graph tells us.

I'm not sure if this is exactly right because the wording of the problem is confusing.
Answer:
a) Number of square feet of wallpaper for bedroom = 12x^2 - 21
b) Number of square feet of wallpaper for living room = 14x^2 - 42
c) Total amount of wallpaper needed = 26x^2 - 63
d) 107 more sq ft of wallpaper will be needed for the living room than bedroom.
Step-by-step explanation:
a) First find the area of each wall.
Length: 3x, Width: 3x, Height: x
(3x × x) + (3x × x) + (3x × x) + (3x × x) = 3x^2 + 3x^2 + 3x^2 + 3x^2 = 12x^2
12x^2 represents the amount of wallpaper needed, including the door. Find the area of the door and subtract it from this value.
3 × 7 = 21
12x^2 - 21 = Total sq ft of wallpaper needed for bedroom
b) First find the area of each wall.
Length: 4x, Width: 3x, Height: x
(4x × x) + (4x × x) + (3x × x) + (3x × x) = 4x^2 + 4x^2 + 3x^2 + 3x^2 = 14x^2
14x^2 represents the amount of wallpaper needed, including the door. Find the area of both doors and subtract it from this value.
3 × 7 = 21 × 2 = 42
42x^2 - 42 = Total sq ft of wallpaper needed for living room
c) Add the two expressions to find the total amount of wallpaper needed.
(12x^2 - 21) + (42x^2 - 42) = 26x^2 - 63
26x^2 - 63 = Total sq ft of wallpaper needed for both rooms
d) Plug x = 8 into the equations found in part a and b.
12(8)^2 - 21 = 747
14(8)^2 - 42 = 854
Subtract these answers to find the difference in amount.
854 - 747 = 107
The living room needs 107 sq ft more of wallpaper than the bedroom
