Answer: The correct answer is C.35.

Step-by-step explanation:

70÷2=35

The value of the measure of XBA is,

⇒ 35 degree

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

Here, ray BA bisects XBY which measures 70 degrees

Hence, The value of the measure of XBA is half of the measure of XBY.

So, We get;

the measure of XBA is,

⇒ 70 / 2

⇒ 35 degree

Thus, The value of the measure of XBA is,

⇒ 35 degree

Answer:

x>-1              or        x<-5

Step-by-step explanation:

4 |x+3|>8

Divide each side by 4

4/4 |x+3|>8/4

|x+3|>2

Absolute value inequalities have 2 solutions, one positive and one negative

Remember to flip the inequality when finding the negative solution

Answer:

-4 degrees

Step-by-step explanation:

Starting at 2 degrees, you need to subract 6 since 200 km= 6 degrees and it decreases.

The temperature after 200 km of the polar bear's journey is -4° C.

A word problem is a verbal description of a problem situation. It consists of  few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

The daily average temperature decreases 3°C for every 100 km traveled

At the start of the bear's journey, the temperature is 2°C

The total distance traveled by the polar bear = 200 km

For 200 km, [tex](3+3)[/tex] totally 6° C should get decreased.

⇒ [tex](2-6)[/tex]

⇒ [tex]-4[/tex]

Hence we can conclude that the temperature after 200 km of the polar bear's journey is -4° C.

Step-by-step explanation:

Area of a triangle = 1/2bh

Let:

base = b = 4 ft

height = h = 3 ft

Solve for the area of the triangle:

A = 1/2(4)(3)

A = 2 * 3

Step-by-step explanation:

Given,7 units away from x axis and 3 units away from y axis,

Coordinates are written in (x,y) form

(x,y)=(7,3)(Given)

Answer:

A

Step-by-step explanation:

7 units away from the origin in the direction of the x-axis

So it can be (7, ?) or (-7, ?)

3 units away in the direction of the y-axis

So it can be (7, 3) or (-7, -3) or other things

Remember: (X, Y)

A is (7,3) which is a possible based on this

B would not work based on this

C would not work either

D wouldn't too

Answer:

The set (39, 80, 89) can be used to make a right triangle. Thus, option D is correct.

Explanation:

We know that right-angle triangles obey the Pythagoras theorem, i.e.,

a² + b² = c²

Let's check for each set:

(39, 41, 45): 39² + 41² ≠ 45²

(39, 49, 59): 39² + 49² ≠ 59²

(39, 69, 99): 39² + 69² ≠ 99²

(39, 80, 89): 39² + 80² = 89²

percentage, a relative value indicating hundredth parts of any quantity.

We can use the formula for compound interest to solve this problem:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

where A is the total amount,

P is the principal

r is the annual interest rate,

n is the number of times the interest is compounded per year, and

t is the number of years.

P = $50,000, r = 0.06, n = 12 and t = 10.

Substituting these values into the formula, we get:

A = 50000(1 + 0.06/12)¹²⁰

A = 50000(1.005)¹²⁰

A=$90970

Answer:

Machine's useful number of years = 9 years

Step-by-step explanation:

Using the straight line method, depreciation is calculated as the difference between the cost of the equipment minus the salvage value, all divided by the number of useful years.

Yearly Depreciation

= (Cost - Salvage value) ÷ (Number of useful years)

Yearly depreciation = P20,000

Cost = P200,000

Salvage Value = P20,000

Number of useful years = n

20000 = (200000 - 20000) ÷ n

20000 = (180000/n)

n = (180000/20000) = 9 years

Answer:

Option D, 7, is the right answer.

Step-by-step explanation:

It is given that 28 slips of papers are numbered through 1 to 28.

Accordingly, there are 28 numbers.

For a fair decision, the number of slips with each one must be the same.

Therefore, the decision will only be fair if the number of people in the group is a factor of 28.

The factors of 28 are -  1, 2, 4, 7, 14 and 28.

In this way, 7 is the only factor of 28 among the given options.

Hence, the answer will be 7.

Answer:

The standard deviation of the sample is 2.55 gigabytes

Step-by-step explanation:

Here we have the responses as follows;

Storage space usage on their computer [tex]x_i[/tex]

The number of respondents or sample size, n = 5

        [tex]x_i[/tex]            [tex](x_i - \bar x)[/tex]         [tex](x_i - \bar x)^{2}[/tex]

        4                -4                 16

        8                 0                  0

        8                 0                  0

        9                 1                   1

        11                 3                  9

∑      40                                   26

The sum = ∑X = 4 + 8 + 8 + 9 + 11 = 40

The mean  = (The sum)/(The count) = 40/5 = 8

Formula for population standard deviation is;

[tex]\sigma = \sqrt{\frac{\Sigma (x_i - \mu)^2}{n } }[/tex]

Where:

σ = Population standard deviation

μ = Population mean

Since we are dealing with only 5 out of her hundreds of coworkers we are dealing with a sample therefore;

The formula for sample standard deviation is;

[tex]s = \sqrt{\frac{\Sigma (x_i - \bar x)^2}{n - 1} }[/tex]

Where:

s = Sample standard deviation

n = Sample size

[tex]x_i[/tex] = Each value of the sample

[tex]\bar x[/tex] = Sample mean

We find each value of [tex](x_i - \bar x)[/tex] by subtracting the x values from the mean, 8, as in the table above, next we find [tex](x_i - \bar x)^{2}[/tex] by squaring the [tex](x_i - \bar x)[/tex].

Next, we find the sum of the differences from the mean square values from the table after which we divide by n - 1, to get [tex]{\frac{\Sigma (x_i - \bar x)^2}{n - 1} } = \frac{26}{5 - 1} = \frac{26}{4} = 6.5[/tex]

We find the root of the result which gives us the standard deviation hence

√6.5 = 2.5495.

Standard deviation, s = 2.5495 ≈ 2.55 to two significant places of decimal.

After making a table for summation the standard deviation of the sample is 2.55 gigabytes.

Use the formula for population standard deviation is:

[tex]\sqrt{\dfrac{\sum{(x_i - \mu)^2}}{n}[/tex]

Where:

σ = Population standard deviation

μ = Population mean

The formula for sample standard deviation is;

[tex]\sqrt{\dfrac{\sum{(x_i - X)^2}}{n-1}[/tex]

Where:

s = Sample standard deviation

n = Sample size

[tex]x_i[/tex] = Each value of the sample

X = Sample mean

Since we are dealing with only 5 out of her hundreds of coworkers we are dealing with a sample, therefore;

The storage used is represented by [tex]x_i[/tex]

The number of respondents or sample size represented by n

Then n = 5

The table for summation is attached below.

Find the sum of the differences from the mean square values from the table after which we divide by n - 1,

[tex]\dfrac{\sum{(x_i - X)^2}}{n-1} = \dfrac{26}{5-1}\\\\\dfrac{\sum{(x_i - X)^2}}{n-1} =6.5[/tex]

Find the root of the result which gives us the standard deviation hence

√6.5 = 2.5495.

Hence,

Standard deviation,

s ≈ 2.55 about two significant places of decimal.
