Help pls I have no clue how
Goryan [66]

Answer:

Step-by-step explanation:

By using regression line calculator,

Equation of the regression line from the data given,

y = -0.38993x + 26.95184

Here, y = weekly hours of sport

x = Time to run

For x = 50 minutes,

y = -0.38993(50) + 26.95184

  = 7.45534

  ≈ 8

Since, slope of the given regression line is negative, correlation will be negative (n).

Which of the following is a good representation of a plane?
NikAS [45]
A table top would be a good representation of a plain because it is a flat surface, and isn't a 3D object, if that makes sense. A box wouldn't be a plane because it has 6 different sides but a table only has one side and one plane. hope this helps :)

If a = − 65 and b = 8, the product of a x b models which rule for multiplying integers? What is the product?
DedPeter [7]

Given, a = -65 and b = 8.

We have to find multiplication of them.

a is negative and b is positive. When we multiply them, we know that the multiplication of positive and negative is negative. That means (+)(-) = -.

So (a)(b) = (-65)(8)

= (-)(+)(65)(8) = - (65)(8) = -520

So we have got the required product.

Multiplication of a and b = -520.

The correct option is option C.

What is the population in 2020 of a place that has a population of 4 million people in 2011 and is growing at a rate of 1.3%?
Stolb23 [73]

Answer:

370 million

Step-by-step explanation:

In the 10 years from 2000 to 2010, the population was multiplied by the factor ...

100% + 9.6% = 109.6% = 1.096

In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:

2030 population = (308 million)·(1.096²) ≈ 370 million

O || u find the measure of < 3?
Fudgin [204]

Answer:

vertical angles

∠1 and ∠3 are vertical angles. Their measures are equal, so m∠3 = 90 . ∠1 and ∠2 are supplementary.

Step-by-step explanation:

Remember in every triangle, the sum of the angles adds to 180 degrees. So let us call the smallest angle's measure "A". The largest angle is 3A and the third angle is A+10. So A + 3A + (A + 10) = 180.
