what is the square root of 481

Answer: y= -3x

Step-by-step explanation:

Use the slope-intercept form to find the slope.

m = −3

To find an equation that is parallel to y = −3x + 2, the slopes must be equal. Using the slope of the equation, find the parallel line using the point-slope formula.

(0,0)

m = −3

Using the point-slope form

y − y1 = m (x − x1), plug in

m = −3, x1 = 0, and y1 = 0.

y − (0) = (−3) (x−(0))

Solve for y

y = −3x

Answer:

y=3x+3

Step-by-step explanation:

(2,9)

x=2

y=9

-Slot these numbers into the equation y=mx+c

-Solve for c

y=3x+c

9=3(2)+c (We have substituted y for 9 and x for 2)

-Solve

9=6+c

(rearrange)

c+6=9

c=9-6

c=3

We have found our y-intercept (c)

Add this value into the original equation (replace the other y-intercept with your new value)

y=3x+3

Answer:

261.8 in^3

Step-by-step explanation:

The volume of a right circular cone is  [tex]V=\frac{1}{3} \pi r^2h[/tex].

r is the radius of the circular base (r = 5 in this problem), and h is the height (h = 10 in this problem.

[tex]V=\frac{1}{3} \pi (5^2)(10)=\frac{1}{3}(250\pi) \approx 261.8\text{ in}^3[/tex]

Answer:

1.106 inches squared 2. 60 inches cubed

Step-by-step explanation:

The surface area is just calculated like this 7.5*2*2 (because there are 2 faces) = 30 then 2*4*2= 16 then 4*7.5*2= 60 then you add them to get 106

For the second all you do is multiply the three values which gets you 60

would be amazing if you picked this as brainliest :)

Answer:

Step-by-step explanation:

.Find the surface area

(7,5*4) *2 + (7,5*2) *2 + (4*2) * 2 =

60+ 30+ 16 => 106 inch²

2.Find the volume

7,5 * 2*4 =>60 inch³

Answer:

[tex](a)\ c(x) = 39 + 0.09 x[/tex]

[tex](b)\ \$53.4[/tex]

Step-by-step explanation:

Given

[tex]Base\ Charge = \$39[/tex]

[tex]Rate = 0.09[/tex] per mile

Solving (a): Linear Equation

The total charges (c(x)) is: the base charge + the rate * number of miles (x).

So, we have:

[tex]c(x)= 39 + 0.09 * x[/tex]

[tex]c(x) = 39 + 0.09 x[/tex]

Solving (b): Cost of rent, if miles = 160

This implies that x = 160

So, we have:

[tex]c(x) = 39 + 0.09 x[/tex]

[tex]c(160) = 39 + 0.09 *160[/tex]

[tex]c(160) = 39 + 14.4[/tex]

[tex]c(160) = 53.4[/tex]

Answer:

if it's area, then:

area = 26.41 ft²

Step-by-step explanation:

area = πr² = (3.14)(2.9²) = 26.41 ft²

Answer:

Angle 5 would be 119 degrees.

Step-by-step explanation:

This is because the angle that is 61 degrees and angle 5 are both supplementary angles. Supplementary angles would add up to 180 degrees and would lie on the same side of the line. So 180 minus 61 is 119.

Answer:

Here's the answer! The mean will increase and the median will stay the same.

Step-by-step explanation:

The mean is the average, so if you have larger numbers, the mean will go up, since 6,000 was changed to 7,000 the mean will increase.

For the median, the median is the number in the middle so the other numbers don't really matter, because 7,000 would be the last number in the data set, (it will be last because to find the median you have to order the numbers in least to greatest) it won't change anything because, only the number in the middle numbers

Unrelated to the question but if you need to find the median and the data set has an even amount of numbers, take the 2 numbers in the "middle" and add them together and then divide them by 2.

Example: 3, 8, 17, 23

add 8 and 17 together, divide by 2, you will get 12.5

hence the median is 12.5 of the data set in the example.

Tip: if you have a larger data set, (more numbers, i'm not talking about the value of a number) try crossing out one number from each side, repeat until you get to the middle then you have your median, if there's an even amount of numbers, remember, add then divide by 2!

Hope this helps!

Dang I really took the time to type all that-

If this does help, I'd appreciate getting brainliest.

Answer:

The expected number of red balls in the sample is 1.2857.

Step-by-step explanation:

The balls are chosen without replacement from the sample, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The expected value of the hypergeometric distribution is:

[tex]E(X) = \frac{nk}{N}[/tex]

3 red balls in the sample:

This means that [tex]k = 3[/tex]

3 balls are drawn:

This means that [tex]n = 3[/tex]

Total of 3 + 4 = 7 balls:

This means that [tex]N = 7[/tex]

What is the expected number of red balls in the sample?

[tex]E(X) = \frac{nk}{N} = \frac{3*3}{7} = 1.2857[/tex]

The expected number of red balls in the sample is 1.2857.

Answer:

There are two correct answers:

A. [tex]\sqrt{(-2-7)^{2} +(8-13)^{2} }[/tex]

E. [tex]\sqrt{(7+2)^{2} +(13-8)^{2} }[/tex]

Step-by-step explanation:

The formula for the distance between two points is:

[tex]d=\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]

...in which [tex](x_{1} ,y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] are the two given coordinates.

Same Sides

When the sides are the same then the triangles are congruent. because they all have exactly the same sides. because the two triangles do not have exactly the same sides.

Answer:

The area of their bases are equal.

Step-by-step explanation:

The formula for the volume of a cone and a pyramid is

1/3 pi* area of base * height

So if the heights are the same then the areas of the bases must also be the same.

Answer:

75 students

Step-by-step explanation:

From the table, we can calculate the total number of students surveyed by Michael:

Total student surveyed = 13 + 15 + 32 = 60 students

We can see that out of the 60 students, 15 students played exactly one sport. Hence:

Proportion of students playing exactly one sport = 15 / 60 = 0.25

Based on the result of the survey, if they are 300 students, number of students playing exactly one sport is:

Number of students playing exactly one sport = proportion * total students = 0.25 * 300 students = 75 students
