Answer:

[tex]y = \frac{11}{8}x + 50[/tex]

Step-by-step explanation:

Given

See attachment for plot

Required

The line of best fit

From the attached plot, we have:

[tex](x_1,y_1) = (0,50)[/tex]

[tex](x_2,y_2) = (80,160)[/tex]

Calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{160 - 50}{80-0}[/tex]

[tex]m = \frac{110}{80}[/tex]

[tex]m = \frac{11}{8}[/tex]

The line of best fit is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = \frac{11}{8}(x - 0) + 50[/tex]

[tex]y = \frac{11}{8}x + 50[/tex]

Answer:

The electricity bill will be about $200 when the average temperature reaches 100°F.

Answer:

x = 54, y = 63

Step-by-step explanation:

117° and the left base angle are adjacent and sum to 180°

base + 117° = 180° ( subtract 117° from both sides )

base = 63°

Since the triangle is isosceles ( congruent legs ) then the 2 base angles are congruent , so y = 63

and x = 180 - (63 + 63) ← sum of angles in a triangle

x = 180 - 126 = 54

I believe the answer is 8.16 pardon me if it's wrong.

Answer:

8.18

Step-by-step explanation:

First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 8

Fractional Part: 175

To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.

We use the following rules to round 8.175 to the nearest hundredth:

A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.

B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.

C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.

D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.

With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

8.18

Answer: The distance between (5,3),(1,0) is 25units square.

Step-by-step explanation:

So, I usually plot the points, and conect them first.

And then I draw a right triangle, so draw two line that conect to the line that we need to find the distance, and form a triangle. Make sure that the line from point (5,3)(1,0) is the Pythagorean triples.

Next, you count the units of the two line that makes a right angle. which is 4 units for the first line, and 3 units for the second.

Thirdly, you plug the numbers into the Pythagorean equation, which is a^2+b^2=c^2 (plug it into a and b, it doesn't matter which number for which letter)

4^2+3^2=c^2

16+9=c^2

25=c^2

[tex]\sqrt{25}[/tex] = [tex]\sqrt{c}[/tex]

c=25

Answer:

P(number greater than 4) = 1/6(50)

In numbers 1 to 6 only 5 and 6 are greater than 4.

Hence, the probability that she will get a number greater than 4 is 2 out of 6 or 2/6.

________________________________

The probability that she'll get more than 4 if she throws the dice 50 times–

________________________________

Hence, your answer will be–

Hence, your answer will be–P( Number greater than 4 ) = 2/6 (50)

Answer:

1200

Step-by-step explanation:

Step 1 convert pounds to ounces

1 pound = 16 ounces

So to convert pounds to ounces we multiply by 16

1500 * 16 = 24000

So there are 24000 ounces in 1500 pounds

Step 2 Find how many 20 ounce containers he can fill.

To find out how many 20 ounce containers he can fill we divide the total amount of ounces of butter that he has by 20

So answer = 24000/20

24000 / 20 = 1200

Therefore he can fill 1200 20 - ounce containers

The volume of the cube not filled by the sphere is 3811.209. Option A is the correct.

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic m.

The volume of sphere is found as;;

[tex]\rm V_{sphere}= \frac{4}{3} \pi r^3 \\\\ V_{sphere}= \frac{4}{3} \times 3.14 (10)^3 \\\\ V_{sphere}= 4188.79 \ cm^3[/tex]

The volume of cube is found as;

Volume of cube = Length x width x height

Volume of cube =20 x 20 x 20

Volume of cube = 8000

The volume of the cube not filled by the sphere is found by subtract the volume of the cube by the volume of the sphere.

V=8000 - 4188.790205

V = 3811.209

The volume of the cube not filled by the sphere is 3811.209.

Hence, option A is the correct.
