Answer:

D. rotate 90 counterclockwise then translate 4 units to the right

Answer:

The total value of the investment will be $15,603.38 after 4 years

Step-by-step explanation:

Compound Interest

It occurs when interest in the next period is earned on the principal sum plus previously accumulated interest.

We'll use the formula:

[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

The investment is P=$11,775 at a rate of r=7.10% = 0.071 compounded quarterly. Since there are 4 quarters in a year, n=4. The investment will last t=4 years, thus:

[tex]{\displaystyle A=\$11,775\left(1+{\frac {0.071}{4}}\right)^{4*4}}[/tex]

[tex]{\displaystyle A=\$11,775\left(1.01775\right)^{16}}[/tex]

[tex]\boxed{A = \$15,603.38}[/tex]

The total value of the investment will be $15,603.38 after 4 years

Answer:

A = 50 + 25h

Step-by-step explanation:

You had to take your computer to the shop. The technician charges a flat rate of $50 for looking at your computer and $25 an hour to fix the problem. Create an equation where prepresents how much you will have to pay and his the number of hours it takes to get your computer fixed.

Let the number of hours required to fix the laptop be represented by h

Total Amount required to pay = A

Hence,the Equation is given as:

A = $50 + $25 × h

A = 50 + 25h

Step-by-step explanation:

Answer:

x ≥ -1/2 or x ∈ [-1/2, +∞)

Step-by-step explanation:

2(-4x + 8) ≤ 20

divide both sides by 2

-4x + 8 ≤ 10

move 8 to the right

-4x ≤ 10-8

-4x ≤ 2

divide both sides by -4. Flip the sign since a negative value is being divided

apothem: a line segment drawn from the center of a convex polygon (inscribed in a circle) to the midpoint of any side of the polygon.

regular polygon:a convex polygon in which all of the side lengths are equal and all of the interior angles have equal measure.

inscribed polygon:a polygon that is constructed inside of the circumference of a circle in which the vertices of the polygon lie on the circumference of the circle.

Step-by-step explanation:

The words that matched with the correct definition are given below.

The apothem is the angle between a chord's middle and the circle's center. The apothem of a regular polygon is only the in radius, or the distance from the center to a side.

The correct definitions are:

Apothem : a line segment drawn from the center of a convex polygon (inscribed in a circle) to the midpoint of any side of the polygon.

Regular polygon : a convex polygon in which all the side lengths are equal and all the interior angles have equal measure.

Answer:

The common factors for 7,15,21 7 , 15 , 21 are 1 . The GCF (HCF) of the numerical factors 1 is 1 .

the greatest common factor of 7, 15, and 21 is 21.

To find the greatest common factor (GCF) of 7, 15, and 21, we can start by finding the prime factorization of each number:

7 = 1 × 7

15 = 1 × 3 × 5

21 = 1 × 3 × 7

Next, we identify the common prime factors among the numbers, which are 3 and 7. To find the GCF, we take the product of these common prime factors:

GCF(7, 15, 21) = 3 × 7 = 21

Therefore, the greatest common factor of 7, 15, and 21 is 21.

Answer:

Is the number of tosses for each coin enough for the sampling distribution of the difference in sample proportions PA-PB to be approximately normal?

b. No, 20 tosses for coin A is enough, but 20 tosses for coin B is not enough.

Step-by-step explanation:

a) Data and Calculations:

The probability of coin A landing tails-side up = 0.5

The proportion of times coin A lands tails-side up (PA) = 20 * 0.5 = 10

Therefore, the probability of coin A landing heads-side up = 0.5 (1 - 0.5)  

And the proportion of times that coin A lands heads-side up = 20 * 0.5 = 10.  

The proportion on either side is equally distributed.

This is why 20 tosses for coin A is enough, since the sample proportions PA is approximately normal, symmetric, and equally distributed.  There will be equal amounts of 10 tosses (0.5 *20) for either heads-side up or tails-side up.

For coin B, the probability of landing tails-side up = 0.8

The proportion of times coin B lands tails-side up (PB) = 20 * 0.8 = 16

Therefore, the probability of coin B landing heads-side up = 0.2 (1 - 0-.8)

The proportion on either side is not equally distributed, but skewed.

This is why 20 tosses for coin B is not enough, since the sample proportions PB is not approximately normal, symmetric, and equally distributed.  There will be 16 tosses landing tails-side up (0.8*20) and only 4 tosses landing heads-side up (0.2*20).

The true statement about the sample proportions of coins A and B is (b) No, 20 tosses for coin A is enough, but 20 tosses for coin B is not enough.

The given parameters are:

Coin A

[tex]p = 0.5[/tex] --- the probability of landing tails-side up

[tex]n = 20[/tex] --- number of toss

Coin B

[tex]p = 0.8[/tex] --- the probability of landing tails-side up

[tex]n = 20[/tex] --- number of toss

Start by calculating the expected number of times both coins land on either sides.

For coin A, we have:

Expected number of tails

[tex]Tails = np[/tex]

[tex]Tails = 20 \times 0.5[/tex]

[tex]Tails = 10[/tex]

So, the expected number of heads would be:

[tex]Head = n - Tails[/tex]

[tex]Head = 20 - 10[/tex]

[tex]Head = 10[/tex]

This means that, there will an expected equal amount of outcomes for the heads and tails of coin A.

Hence, 20 tosses is enough for coin A because the proportion is equally distributed and approximately normal.

For coin B, we have:

Expected number of tails

[tex]Tails = np[/tex]

[tex]Tails = 20 \times 0.8[/tex]

[tex]Tails = 16[/tex]

So, the expected number of heads would be:

[tex]Head = n - Tails[/tex]

[tex]Head = 20 - 16[/tex]

[tex]Head = 4[/tex]

This means that, there won't be an expected equal amount of outcomes for the heads and tails of coin B.

Hence, 20 tosses is not enough for coin B because the proportion is neither equally distributed nor approximately normal.

So, the correct option is (b)
