Answer:

0.44444444 or 4/9

Step-by-step explanation:

Since we know the value of [tex]x[/tex], we can rewrite the equation replacing the variables.

[tex]\frac{2}{3}^{2} + 3*\frac{2}{3} - 2[/tex]

Now solve. While solving, remember the order of operations.

[tex]\frac{2}{3}^{2} + 3*\frac{2}{3} - 2 = 0.44444444[/tex] or [tex]\frac{4}{9}[/tex]

Answer:

13 5/8 Or 13.625

Explanation:

• Let's start with 1/4. There are five days that has the amount of 1/4 of rainfall.

So we have to add all five of the 1/4 or just multiply:

1/4 x 5 = 5/4

• Now for the 3/8. There are twelve days that has that amount of rainfall.

3/8 x 12 = 36/8

· For 1/2. There are five days.

1/2 x 5 = 5/2

· For 5/8. There's five days.

5/8 x 5 = 25/8

• Lastly for 3/4. There is three days.

3/4 x 3 = 9/4

• Now we add all of the amount together: 5/4 + 36/8 + 5/2 + 25/8 + 9/4

- To add, we have to find the Least Common Denominator (LCD), which is 8.

So we have to make all of the fractions into a denominator of 8 by multiplying:

5/4 –> 10/8 (Multiply by 2)

36/8 (Stays the same, already have the denominator of 8)

5/2 –> 20/8 (Multiply by 4)

25/8 (Stays the same, already have the denominator of 8)

9/4 –> 18/8 (Multiply by 2)

• Now add:

10/8 + 36/8 + 20/8 + 25/8 + 18/8 = 109/8

109/8 = 13 5/8

Or as decimal form: 13.625

Answer:

  (25/3)π

Step-by-step explanation:

A central angle of 120° is 1/3 of a circle, so the arc length will be 1/3 of the circumference:

  (1/3)(25π) = (25/3)π ≈ 26.18 . . . . units

Answer:

Circumference = 25π

Total angle made by circle = 360

Now,

120 is ⅓ of 360⁰.

⅓ × 25π = 25π/3

Hence,

Length of arc = 25π/3

The confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64). Then the correct option is C.

If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.

Let the sample mean given as μ and

The sample standard deviation σ, and

The sample size = n, and

Then the heights would be outside the 90% confidence interval will be

For 90% confidence interval, we have z = 1.645

⇒ μ ± z (σ/√n)

Kat is interested in getting chickens, so she can have fresh eggs.

Before she buys her chickens, she wants to find the mean number of eggs each one will lay.

She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month.

She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs.

The 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay in one month will be

⇒ μ ± z (σ/√n)

⇒ 24.8 ± 1.645 (6.9/√40)

⇒ 24.8 ± 1.84

Then the confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64).

Then the correct option is C.

Answer:

m = -20

Step-by-step explanation:

first distribute:

-4(m + 18) = 8

-4m - 72 = 8

Now add 72 to both sides to get m by itself

-4m = 80

and divide by -4 on both sides

m = -20

Hope this helped! :)

Answer: m = -20

Step-by-step explanation:

−4(m + 18) = 8

Step 1: Simplify both sides of the equation.

−4(m + 18) = 8

(−4)(m) + (−4)(18) = 8 (Distribute)

−4m + −72 = 8

−4m − 72 = 8

Step 2: Add 72 to both sides.

−4m − 72 + 72 = 8 + 72

−4m = 80

Step 3: Divide both sides by -4.

−4m / − 4 = 80 / −4

m = −20

Answer:336

Step-by-step explanation:

I'll do problem 1 to get you started. The completed filled out table is shown below in the attached image.

We have x as the input and y as the output. The observed value is the second column, and this is the actual y value we're aiming for. The predicted value is an estimation based on what the linear regression line says. The residual is the error or gap between the observed and predicted.

With that in mind, let's fill out the table. In the first row, we have x = 5 pair up with y = 3. The predicted y value is y = 0.5x = 0.5*5 = 2.5, meaning we'll write "2.5" without quotes in the first blank space of that first row. The residual is

e = error or residual

e = (observed y value) - (predicted y value)

e = (3) - (2.5)

e = 0.5

A positive residual means that the observed y value is larger than the predicted one. The predicted y value is an under-estimate. We'll write "0.5" without quotes underneath "residual" in the first row.

-------------------

We'll repeat the same steps for row 2

This time we have x = 10 lead to a predicted y value of y = 0.5*x = 0.5*10 = 5

The residual is

e = (observed) - (predicted) = (4) - (5) = -1

The negative residual tells us the observed value is smaller than the predicted one. The predicted value is an over-estimate.

--------------------

For row 3, we have the input x = 15 lead to a predicted y value of y = 7.5 since y = 0.5*x = 0.5*15 = 7.5

The residual is therefore: e = (observed y) - (predicted y) = (9) - (7.5) = 1.5

The nice thing about how this table is set up, is that the observed y values are listed first, then the predicted y values next. This may help you remember how the order of subtraction will go.

The steps for rows 4 through 6 are the same as mentioned earlier, so there's nothing new here.

The completed table for problem 1 is shown below in the attached image.

Step-by-step explanation:

So first Maya throws the rock from the 192-foot cliff into the ocean.

After 2 seconds, the rock reaches a maximum height of 256 feet;

After 4 seconds, the rock reaches the ocean.

Good luck!

The required equation that represents the scenario is x = 64 * 2 + 256 * 4

Given that,
Maya throws a rock straight up from the edge of a 192-foot cliff and into the ocean. After two seconds, the rock reaches a maximum height of 256 feet. Four seconds later, the rock enters the ocean. To write an equation to model the scenario.

the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,
let the total distance covered by the rock vertically be x,
now,
Distance traveled by the rock vertical upward in 2 seconds = 2 * (256 - 192)
                                                                                          = 2 * 64
Distance traveled by the rock vertical downward in 4 seconds = 4 * 256
Total distance,
x = 2 * 64 + 4 * 256

Thus, the required equation that represents the scenario is x = 64 * 2 + 256 * 40.

Any number which has digit 2 at its thousandth place will have  the digit 2 one hundred times larger than it is in the number 524

Place value is the value of each digit in a number.

For example, the 5 in 350 represents 5 tens, or 50; however, the 5 in 5,006 represents 5 thousands, or 5,000.

It is important that while a digit can be the same, its value depends on where it is in the number.

Given that, we need to determine that which number is the digit 2 one hundred times larger than it is in the number 524,

So, if we consider a number having 2 at its thousandths place,

For example : 32000, the place value of 2 is 2000,

In the number 524, the place value of 2 is 20,

Now, 2000/20 = 100

So, here we see that, the digit 2 in 32000 is 100 times larger than the digit 2 in 524

Hence, any number which has digit 2 at its thousandth place will have  the digit 2 one hundred times larger than it is in the number 524

Answer:

6%

Step-by-step explanation:

Given data

Principal = ​$1,000

The expression for the simple interest is

Simple interest= PRT/100

Substitute

480= 1000*R*8/100

Cross multiply

480= 8000R/100

480*100= 8000R

48000= 8000R

Divide both sides by 8000

R= 48000/8000
