If Esther deposited $50 at the end of each month into an account with no interest, how much money would she have saved by the end of 12 months?

Answer:

Question 4: The set has 66 as an outlier and removing it increases the mean by about 1.3 inches.

Question 5: The set has 50 as an outlier and removing it increases the mean by about 3.

Step-by-step explanation:

Question 4:

Given heights are:

66, 74, 76, 77, 78, 79, 80, 80, 82, 84

The mean is: 77.6 inches

Removing 66 will make the mean increase to 78.9

So,

The set has 66 as an outlier and removing it increases the mean by about 1.3 inches.

Question 5:

50, 74, 76, 77, 78, 79, 80, 80, 82, 84

The mean is 76.

We can clearly see that 50 is an outlier as it is quite less than the given data.

Calculating mean after removing 50 will give us mean equal to 78.9

So the correct answer is:

The set has 50 as an outlier and removing it increases the mean by about 3.

Answer:

A) A(p(t)) = 25πt²

B) 314 square units.

Step-by-step explanation:

Part A)

Flow of paint can be expressed by the function:

p(t) = 5t

Area of the pattern is expressed as:

A(p) = πp²

Since area is given in terms of p, we can use the expression of p to express the area of pattern in terms of time(t). Using the value, we get:

A(p(t)) = π (5t)²

A(p(t)) = 25πt²

Part B)

We have to calculate the area of the pattern after time t. Substituting the value of t in above expression, we get:

A(p(2)) = 25 x 3.14 x 4 = 314 square units.

Therefore, the area of spilled paint after 2 minutes will be 314 square units.

Answer:

○ D. 116°

Step-by-step explanation:

Think of the Unit Circle. You know that half of 360° is 180°, and that angle has a measure of 58°, so you do this:

-58° + 180° = 122°

Now, that chord of the circle drags it a bit by a few units, so that will be approximately 116°.

So, rewriting the expression we have:

[tex]\sqrt [9] {a ^ 4}[/tex]

Answer:

Option 4

Answer: OPTION 4.

Step-by-step explanation:

By definition, Radical expressions are those that use a root.

In this case you have this expression:

Answer: 10 units

Step-by-step explanation:

The length of one side of the given rhombus is; C: 10 units

The half diagonals of a rhombus are the legs of a right angle triangle with the hypotenuse being the side of the rhombus.

We see that EG and FH are the diagonals of the rhombus. This means that the half-diagonals measure 8 and 6.

Using Pythagoras theorem, we can find the hypotenuse which is the length of the side of the rhombus.

Thus;

8² + 6² = c²

64 + 36 = c²

100 = c²

c² = 100

c = 10

Answer: 82%

Step-by-step explanation: Count the total number of marbles.

9+6+7+11=33 marbles in total.

We are trying to find the probability of NOT picking a blue marble. There are 6 blue marbles. Subtract the blue marbles from the total.

33-6=27

The probability of not picking a blue marble is 27/33. Divide the fraction.

27/33=0.82

Multiply by 100 to get the percent.

0.82 x 100 = 82%

There is an 82% chance of not picking a blue marble.

The inverse of [tex]\( f(x) = -2x + 3 \)[/tex] is [tex]\[ f^{-1}(x) = \frac{x - 3}{-2} \][/tex].

To find the inverse of f(x) = -2x + 3 , you need to interchange  x  and  y and solve for y .

Start with y = -2x + 3 .

Swap x  and y  to get  x = -2y + 3 .

Solve this equation for  y .

x = -2y + 3

First, subtract 3 from both sides:

x - 3 = -2y

Then, divide both sides by -2 :

[tex]\[ \frac{x - 3}{-2} = y \][/tex]

Thus, the inverse of [tex]\( f(x) = -2x + 3 \)[/tex] is:

Answer:

2x-y = -4

Step-by-step explanation:

We can use the point slope form of a line to write the equation and then convert it to standard form

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y-2 =2(x--1)

y-2 =2(x+1)

y-2 =2x+2

The standard form is Ax +By =C

Subtract 2x from each side

-2x +y -2 =2x-2x+2

-2x+y-2 =2

Add 2 to each side

-2x+y -2+2 =2+2

-2x+y=4

The x term should be positive

Final answer:

To find a system with the same solution, multiply one of the original equations by a constant and/or add the two original equations together to derive a new equation. An example is the alternative system 6x - 8y = -36 and 9x - 2y = -24, which shares the same solution as the original.

Explanation:

To find a system of equations with the same solution as the given system:

6x + 2y = −6

3x − 4y = −18

We must ensure that the alternative system is equivalent, meaning they share the same solution. A common technique is to multiply both sides of one or both of the equations by a constant to create new equations that have the same solutions. For example, we could multiply the second equation by 2:

3x − 4y = −18 becomes 6x − 8y = −36 after multiplying by 2.

Then, to avoid having the same equation, we could add the original second equation to the first one to get a different second equation:

6x + 2y + (3x − 4y) = −6 + (−18) becomes 9x − 2y = −24.

So, the alternate system that shares the same solution as the original would be:

6x − 8y = −36

9x − 2y = −24

Answer:

(-1,-5)

Step-by-step explanation:

So we have the system:

y=3x-2

x-y=4.

We are asked to use substitution. Luckily, it is already setup for this because one of the equations has one of the variables solved for, namely the y=3x-2 equation.  We are going to insert y=3x-2 into x-y=4 and solve for x.

x-y=4  (with y=(3x-2) ):

x-(3x-2)=4

Distribute:

x-3x+2=4

Combine like terms:

-2x+2=4

Subtract 2 on both sides:

-2x    =2

Divide both sides by -2:

 x     =-1

Now if y=3x-2 and x=-1, then y=3(-1)-2=-3-2=-5.

So the solution is (-1,-5).

Answer:

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides = a : b

and ratio of areas = a² : b²

Here the ratio of areas = 7 : 28 = 1 : 4, hence

ratio of sides = [tex]\sqrt{1}[/tex] : [tex]\sqrt{4}[/tex] = 1 : 2

Answer:

100 is the number which can be multiplied to eliminate the decimals....

Step-by-step explanation:

Given:

Which number can each term of the equation be multiplied by to eliminate the decimals before solving

5.6j – 0.12 = 4 + 1.1j

Solution:

Notice that the constants and the coefficients in this equation contains decimal. All the numbers are in decimal up to tenth place except 0.12 which has decimal up to hundredth place.

Therefore, if we want to eliminate the decimal from 0.12 we have to multiply it by 100.

Thus the given equation will be multiplied by 100 to eliminate decimal from the terms.

100(5.6j – 0.12 = 4 + 1.1j)

By multiplying the equation by 100 we get:

560j - 12 = 400 + 110j

Thus 100 is the number which can be multiplied to eliminate the decimals....

Answer:

100

Step-by-step explanation:

Well, to answer this question, you have to find the number/coefficient that has the most numbers after a decimal point (not including trailing zeros), and then use the rule 10^(numbers after the decimal point) to see how to eliminate the decimals. So, 2 digits, 10^2=100

Firstly, find the slope.

Let m = slope

m = (8 - 4)/(1 - 0)

m = 4/1

m = 4

Now use the point-slope formula.

y - y_1 = m(x - x_1)

Pick one of the given points. I will use the point (0, 4) but you can certainly use (1, 8) if you'd like.

We now plug and chug.

y - 4 = 4(x - 0)

y - 4 = 4x

y = 4x + 4

Replace y with f(x).

f(x) = 4x + 4

Did you follow?

Answer:

f(x) = 4 x (2)^x  

Step-by-step explanation:

6 units right is the answer, since plugging in values(since it's asking for the translation you can ignore the -3) so your answer is:

The graph is translated 6 units RIGHT
