suppose you've noticed that your score is to the left of your friend's when placed on a normal distribution. This means that your score is ______________ than her score.

**rate of change for f(x)**

f(x)=-0.3x^2

-0.3(1)^2=-0.3^2=-0.09

-0.03(5)2=-0.15^2=-0.0225

rate of change = (-0.0225-(-0.09))/(5-1)=0.0675/4=0.016875

f(x) rate of change is 0.016875 or about 0.02

**rate of change for g(x)**

g(x)=-0.6x^2

-0.06(1)^2=-0.06^2=-0.0036

-0.06(5)^2=-0.3^2=-0.09

rate of change = (-0.09-(-0.0036))/(5-1)=-0.0864/4=-0.0216

g(x) rate of change is -0.0216 or about -0.02

**how much greater?**

0.02(-1)=-0.02

g(x) is -1 times of f(x)

Answer:

[tex]3x-7y=-10_{(1)} \\x=5y+2_{(2)}\\[/tex]

Substituting Equation 2 into equation 1

[tex]3(5y+2)-7y=-10_{(3)} \\15y+6-7y=-10\\15y-7y+6=-10\\8y+6=-10\\8y=-10-6\\8y=-16\\y=\frac{-16}{8} \\y=-2\\[/tex]

Substitute the value of y into Equation 2

[tex]x=5y+2\\x=5(-2)+2\\x=-10+2\\x=-8\\[/tex]

The unit circle is a particular case of the Pythagorean theorem, in which hypotenuse ([tex]r[/tex]) has a measure of a unit. That is:

[tex]x^{2}+y^{2} = r^{2}[/tex]  (1)

Step-by-step explanation:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).

The amount of water the fish tank can hold is 3375 inches³.

where

l = length

Therefore,

length = 15 inches

How much water the tank can hold is the volume of the tank. Therefore,

v = l³

v = 15³

v = 15 × 15 × 15

v = 3375 inches³

Answer: the answer is 33/100 or .33

Answer:

33/100

Step-by-step explanation:

Because since 4/10 + ?= 73/100 that means the denominator get's change so we know that the demonter for the ? number had to have 100 as a denominator.

And since that number has a 100 for their demonter that means we times our demonter(10 until it get's to 100 so how many times do we times 10 to it get's to 100? the answer is 10.

So since we times our denominator we also have to times our numerator by 10 as well what is 4 times 10? Our answer is 40.

So now our fraction 4/10 is now 40/100. what= 73 when you add it to 40?

Our answer for that is 33 how I know is 40+ 33= well lets add the tens what is 40 + 30=70 now add ones 3 so 73 and our denominator is already the same and our fraction now is 73/100. and there's our answer.

4/10(40/100 now because of the calculations) + 33/100=73/100 so we figured out our mysterious fraction| Mysterious fraction=73/100.

Step-by-step explanation:

cosine is cos(angle)= adjacent/hypotenuse

sine is sin(angle) = opposite/hypotenuse

Tangent is tan(angle)= opposite/adjacent

for all of those

if the equation is something like tan(69)= x/69

multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator

if it is something like tan(69)= 69/x

just swap x and tan(69)

it is much easier

it will then be 69/tan(69) and put that in the calculator

Answer:

I'm guessing the question asks us what is the current balance of the dress after 7 weeks.

So it if drops by 10% every week, we need to find how much it went down one week;

consider 10% as 10/100 in fraction form;

10/100 x 150 = $15, it goes down by $15 each week, but we need to find how much 7 weeks would be:

7 x $15 = $105, it went down $105 so we need to subtract that from the total:

150 - 105 = $45, it would now be currently up for sale for $45.

If the total number of juice boxes is 20 and to distribute the juice boxes among 6 friends, The number of juice boxes can you give to each friend will be 3.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

You are given 20 juice cartons, which you distribute to each of your friends. You want to give the same number of juice boxes to each of your six friends.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

The number of juice boxes can you give to each friend is,

=20/6

=3.333 ≈ 3

Thus, if the total number of juice boxes is 20 and to distribute the juice boxes among 6 friends, The number of juice boxes can you give to each friend will be 3.

x - 3y = -11
-x + 2y = 7

We minus these equations : x - 3y - (-x + 2y) = -18

= x - 3y + x - 2y = -18
2x - 5y = -18

Now, we add these equations :

x - 3y = -11
-x + 2y = 7
-> x - 3y - x + 2y = -4
-y = -4
y = 4

Replace it in 2x - 5y = -18

2x - 20 = -18

2x = -18 + 20 = 2
x = 1

Recheck : 1 - 3 x 4 = -11

-1 + 8 = 7.
