Answer:

[tex] y = 15x + 20 [/tex]

x = 11, when y = 185

Step-by-step explanation:

Given:

(0, 20);

(2, 50)

Required:

Equation of the line;

Value of x, when y = 185

SOLUTION:

Equation of the line can be written using the slope-intercept formula, given as, [tex] y = mx + b [/tex].

m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} =\frac{50 - 20}{2 - 0} = \frac{30}{2} = 15 [/tex]

b = y-intercept = the pointt at which the line cuts the y-axis = 20

Plug in the value into the formula to get the equation:

[tex] y = mx + b [/tex]

[tex] y = 15x + 20 [/tex]

Use this equation to solve for x, when y = 185

[tex] y = 15x + 20 [/tex]

[tex] 185 = 15x + 20 [/tex] (substitution)

[tex] 185 - 20 = 15x + 20 - 20 [/tex]

[tex] 165 = 15x [/tex]

[tex] \frac{165}{15} = \frac{15x}{15} [/tex]

[tex] 11 = x [/tex]

x = 11, when y = 185

Answer:

The probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

Step-by-step explanation:

Let X denote the number of adults who says that he or she was too young to get tattoos.

The probability of selecting an adults who says that he or she was too young to get tattoos is, p = 0.20.

Five adults who regret getting tattoos are randomly selected.

The events of any of these five adults regretting getting tattoos is independent of each other.

The random variable X follow a Binomial distribution with parameters n = 5 and p = 0.20.

Compute the probability that exactly one of the selected adults says that he or she was too young to get tattoos as follows:

[tex]P(X=x)={5\choose x}(0.20)^{x}(1-0.20)^{5-x}\\\\P(X=1)={5\choose 1}(0.20)^{1}(0.80)^{5-1}\\\\[/tex]

                [tex]=5\times 0.20\times 0.4096\\\\=0.4096[/tex]

Thus, the probability that exactly one of the selected adults says that he or she was too young to get tattoos is 0.4096.

Answer:

If M is mid point then XM = MY

2x +5 = 3x -1

2x - 3x = -1 - 5

-x = -6....so

x = 6

MY = 3(6) -1

MY = 18 -1

MY = 17

the answer is B for this question

The equation for f(x) if the independent value is 2 will give a result of 13 is (x) = 3x² + 1

Given the expression f(2) = 13, we need to find the function such that when the input value is 2, the output value will be 13.

Using the function f(x) = x² + 8

f(2) = 2² + 8

f(2) = 4 + 8 =12

Using the function f(x) = 3x² + 1

f(2) = 3(2)² + 1

f(2) = 12 + 1 =13

Hence the equation for f(x) if f(2) = 13 is (x) = 3x² + 1

Answer:

315 inches long

Step-by-step explanation:

180 x .75= 135 <--- that is 75% of 180

then add the two numbers

180 + 135

you add them because the original length of the car is 180 inches and the truck is 75% longer.

180 + 135= 315

Answer:

Angle BEC = 108°

Step-by-step explanation:

Vertical angles formed when two straight lines intersect are always congruent to each other. That is, the vertical opposite angles formed are of the same measure.

Angle AED = 108°

Angle AED and angle BEC are vertical opposite angles form by intersecting lines, therefore, angle AED = angle BEC.

Angle BEC = 108°

Answer:

The answer is "About 421.6 and 578.4 the middle of 95% of both the wires of the A business checked".

Step-by-step explanation:

The Mean = Median = Mode= 500 for company A  

It also will see company A as a regular delivery  

Mean > Median > Mode for the business B  

Company B would seem to have a correct warped delivery

The value of Z varies in the center of 95% of the wires: [tex](-1.96\ \ from \ \ 1.96)[/tex]

[tex]\text{The lower bound} = Mean - 1.96 \times \sigma[/tex]

                           [tex]= 500 - 1.96 \times 40 \\\\= 500 - 78.4\\\\= 421.6[/tex]

[tex]\text{The upper limit = Mean} + 1.96 \times \sigma[/tex]

                         [tex]= 500 + 1.96 \times 40 \\\\= 500 + 78.4 \\\\= 578.4[/tex]

The ratio of teachers to students is B) 1:18

Step-by-step explanation:

Simply divide the number of teachers to the number of students

630/35 = 18

Therefore the ratio between teachers to students is 1:18, meaning that there is 1 teacher designated for every 18 students.

Answer:

Graph attached.

Step-by-step explanation:

The product of slope of line (i) and slope of line (ii) should be equal to -1 (product of slopes of two perpendicular lines = -1)

i.e

Slope of line (i) × 2 = -1

Slope of line (i) = [tex]-\frac{1}{2}[/tex]

To find the equation of line (i), we need another point (x,y) on the line.

Slope (m) = change in y ÷ change in x = [tex]\frac{y - -3}{x - 0} = -\frac{1}{2}[/tex]

y = [tex]-\frac{1}{2} x[/tex] - 3

Answer:

61 degrees

Step-by-step explanation:

Let's do this

So we know all the angles measure in a triangle will be 180 degrees

We have 56 and 63

To find the third, let's add and subtract

56+63=119

Now let's subtract from 180

So 180-119=61

The third angle measures 61 degrees

Now let's add them up and see if they total 180 degrees

So 56+63+61=180

Yay, we found the answer!

The answer is 61 degrees.

Let Alyssa's horse's age be x .

Then :-

Alyssa's age = 2x

Age of her horse when it died = 24

Alyssa's age when her horse died =

[tex]2x \\ = 2 \times x \\ = 2 \times 24 \\ = 48 \: years[/tex]

∴ Alyssa was 48 years old when her horse Midnight died .

Answer:

29

Step-by-step explanation:

Alyssa was twice the age of midnight so 10 ÷2 =5(age gap)

Midnight died at 24 so Alyssa was 29 that time because

24+5(age gap) =29
