Step-by-step explanation:

i'm so sorry if it's incorrect; good luck anyways :)

Answer:

3.947

Step-by-step explanation:

7 wholes = 7

one half = 0.5

1 whole = 1

nine tenths = 0.9

7.5/1.9 ≈ 3.947

Answer:

840

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 14 - 7 = 21 - 14 = 7

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 7 , thus

[tex]a_{120}[/tex] = 7 + (119 × 7 ) = 7 + 833 = 840

Answer:

(-2.5, -3.5)

Step-by-step explanation:

In order to find midpoint, you must add both x coordinates then divide by two and add both y coordinates then divide by two.

1 + (-6) = -5

-5/2 = -2.5

1 + (-8) = -7

-7/2 = -3.5

Answer:

[tex]A\approx\$880.68[/tex]

Step-by-step explanation:

So, we know that Jolene bought an initial $750.

We also know that the purchase is increasing at an average rate of 5 1/2 %or 5.5%. In other words, this is being compounded.

So, we can use the compound interest formula, which is:

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

Where A is the total amount, P is the principal value, r is the rate and n is the number of times compounded per year, and t is the amount of years.

So, substitute 750 for P. 5 1/2% is the same as 5.5% or 0.055 (you move the decimal two places to the left and remove the percent symbol) so substitute this for r. Since it's increasing yearly, n is 1. So, our formula is:

[tex]A=750(1+0.055)^t[/tex]

Add:

[tex]A=750(1.055)^t[/tex]

Since the stock was bought 3 years ago, the value now is t=3. So, substitute 3 for t and evaluate:

[tex]A=750(1.055)^3[/tex]

Evaluate. Use a calculator:

[tex]A\approx\$880.68[/tex]

And we're done!

Formula: A = P(1 + r/n)^t

We have these variables:

P = 750

r/n = 0.055

t = 3

Substitute and simplify:

A = 750(1 + 0.055)^3

A = 750(1.055)^3

A = 880.68

Best of Luck!

Step-by-step explanation:

1/2(8-6x)=x

Distribute

1/2 * 8 - 1/2 * -6x = x

4 -3x = x

Add 3x to each side

4 -3x+3x= x+3x

4 = 4x

Divide each side by 4

4/4 = 4x/4

Hi !

C₁ = 2π×r₁

C₂ = 2π×r₂

C₂ - C₁ = 2π×r₂ - 2π×r₁

= 2π(23cm - 16cm)

= 2×3.14×7

= 43.96 cm

≈ 44 cm

Good luck !

Answer:

44 cm

Step-by-step explanation:

r = 16,R = 23;2πR - 2πr

Step-by-step explanation:

4x + 9 = 56

The value of x.

4x + 9 = 56

The value of 9 changes when we take 9 to the Right Hand Side, we get

4x = 56 - 9

Now, The value of 4 changes when we take 4 to the Right Hand Side, we get

x = 47/4

The value of x is 47/4

Answer:

For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Step-by-step explanation:

The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.

A linear regression is represented as [tex]^\wedge y = mx + c[/tex].

The true option is:  E. For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Given that:

[tex]^\wedge S = 0.5 + 1.1L[/tex]

From the general linear equation, we have:

[tex]1.1 \to[/tex] The slope

[tex]0.5 \to[/tex] The y-intercept

The slope is the difference between the sales price of one listing and the next.

From the question, we understand that the listed amount is in 100,000's.

This means that there is an increment of [tex]\$1.1 \times 100000[/tex] between the sales price of concurrent listing

So, we have:

[tex]\$1.1 \times 100000 =\$110000[/tex]

From the list of given options (see attachment), we can then conclude that (e) is correct.

Hence, for each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.

Answer: B. $112 = $16 x

Hope this helps!

The Definition Of a Midpoint says that is B is the

midpoint of segment AC, then segment AB ≅ AC.

Since segment AB ≅ segment BC, we can setup

the equation 2(3x - 1) = 8x - 20 and we can solve from here.

Start by distributing the 3 through the parenthses on the left side.

So we get 6x - 2 = 8x - 20.

Now subtract 8x from both sides to get -2x - 2 = -20.

Now add 2 to both sides and we have -2x = -18.

Finally, dividing both sides by -2, we find that x = 9.

If x = 9, segment BC must be 3(9) - 1 or 27 - 1 which is 26.
