What is the approximate equation of this line of best fit in slope-intercept form?
y = −13x + 13 over 10
y = negative 13 over 10x + 13
y = negative 10 over 13x + 13
y = −13x + 10 over 13
Answers
Answer:
Step-by-step explanation:
y = negative 13 over 10x + 13 is the best choice. (0, 13) is the y-intercept. If we begin at (0, 13) and move approximately 10 units to the right, y decreases by 13, so the slope is m = -13/10.
Writing y = negative 13 over 10x + 13 as y = negative 13 over 10 plus 13 would be clearer. We must emphasize that the slope is -13/10 and that this should be enclosed in parentheses: y = (negative 13 over 10)x + 13.

A rhombus has sides 10 cm long and an angle of 60°. Find the diagonals of the rhombus.
Answers
Since all the sides are equal, the altitude is
10 sin60° = 5√3
To see this, draw the rhombus ABCD and drop an altitude from D to AB. Now you have a right triangle with hypotenuse=10 and base angle=60°

(1 point) Question 14 options: 1) Step 3; 2 + (4 + 6x) 2) Step 3; 2 + (4 ⋅ 6x) 3) Step 2; 2(4) + 2(4x) 4) Step 2; 2(3) + 2(4x)
Answers
Step-by-step explanation:
Hello,A=IxwStep 1:6+8xStep 2:2(3)+2(4x)Step 3:2(3+4x)Step 4:The dimension of the rectangle are 2 and 3+4x. As a result, Students makes the mistake at Step 2; 2(3)+2(4x). Hope it help!Answer: (4)
Step-by-step explanation:
At step 2 the student rewrites 6 as 2*(4), and 8x as 2*(6x). This is incireect, since 2*(4) is actually 8, and 2*(6x) is 12x.
The correct way to do it is to rewrite 6 as 2*(3), and rewrite 8x as 2*(4x), which corresponds to the answer option (4)
A probability model includes P(red) = 27 2 7 and P(blue) = 314 3 14 . Which of the following probabilities could complete the model? Select all that apply. A.

P(green) = 37 3 7 , P(yellow) = 114 1 14
Answers
Answer:
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]P(Red) = \frac{2}{7}[/tex]
[tex]P(Blue) = \frac{3}{14}[/tex]
Required
Which completes the model
Let the remaining probability be x.
Such that:
[tex]P(Red) + P(Blue) + x = 1[/tex]
Make x the subject
[tex]x = 1 - P(Red) - P(Blue)[/tex]
So, we have:
[tex]x = 1 - \frac{2}{7} - \frac{3}{14}[/tex]
Solve
[tex]x = \frac{14 - 4 - 3}{14}[/tex]
[tex]x = \frac{7}{14}[/tex]
[tex]x = \frac{1}{2}[/tex]
This mean that the remaining model must add up to 1/2
[tex](a)\ P(Green) = \frac{2}{7} ; P(Yellow) = \frac{2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{7} + \frac{2}{7}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{2+2}{7}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{7}[/tex]
This is false because: [tex]\frac{4}{7} \ne \frac{1}{2}[/tex]
[tex](b)\ P(Green) = \frac{3}{8} ; P(Yellow) = \frac{1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{3}{8} + \frac{1}{8}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{3+1}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{4}{8}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
[tex](c)\ P(Green) = \frac{1}{4} ; P(Yellow) = \frac{1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{4} + \frac{1}{4}[/tex]
Take LCM
[tex]P(Green) + P(Yellow)= \frac{1+1}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{2}{4}[/tex]
[tex]P(Green) + P(Yellow)= \frac{1}{2}[/tex]
This is true
Other options are also false

Answer 66,814000 or 6.6814x10 exponent of 7
Step-by-step explanation:
To get the answer you have to subtract 6.7x10exponent of 7 by 1.86x10 exponent of 5
6.0 minutes taken by light from the Sun to reach Venus
What is distance formula?distance = speed × time. time = distance ÷ speed.
given that:
Venus is approximately 6.7 × 107 miles from the Sun.
speed of light 1.86 × 105 miles per second.
Now, time taken by Venus to reach sun
= 67000000/186000
= 360.21 seconds
=6.0 minutes.
Hence, the time taken to reach by the sun to sun is 6 minutes.

A cone has a height of 10 yards and a diameter of 8 yards. What is the volume?

Answer: 167.55 units cubed
Step-by-step explanation:
To find this, you must know the formula for a cone. The area is A=πr(r+h2+r2). We can get that the A=π4(4+102+(4)2). We got this from plugging in the numbers. The radius is equal to half the diameter, so the radius is 4. The answer is 167.55 units cubed.

Answers
Answer:
Answer is 71°
Step-by-step explanation:
Two angles are said to be
supplementary angles if their
sum is 180°.
******************************************
one angle ( x ) = 109°
Let the second angle = y
x + y = 180°
=> y = 180° - x
=> y = 180° - 109°
=> y = 71°
So,
Supplementary angle of 109° should be 71°

D.

Answers
Answer:
C
Step-by-step explanation:
First, we have to find the equation that will give the rabbit population as a function of time and the initial population.
The equation we need turns out to be Population = a0 x 3y where a0 is the initial population and y is the number of years,
To find the rabbit population when a0 = 30 and y =3, use the equation to get Population = 30 x 33 = 810.
You can now find the difference in the number of rabbits at year 3 for the different starting populations.

what is the ratio of water around in swamps to the total quantity of fresh water on the surface?
Answers
Answer:
Of the liquid surface fresh water, 87% is contained in lakes, 11% in swamps, and only 2% in rivers.
Step-by-step explanation:
The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.
3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.11
Rain and seasonal flooding cause water levels to fluctuate. In the wet soil, water-tolerant vegetation grows and helps maintain a moist, swampy condition. In many freshwater swamps in the southeastern United States, cypress and tupelo trees grow. ... Alligators, frogs, and many other animals live in these swamps.
