julio distributed a survey to his fellow students asking them how many hours they spent playing sports in the past day. He also

asked them to rate their mood on a scale from 0 to 10, with 10 being the happiest. Julio created the following scatterplot and regression line to show this relationship. The fitted line has a y-intercept of 5. What is the best interpretation of this y-intercept?

Answer:

The least mood value.

Step-by-step explanation:

If Julio has rated their mood on a scale from 0 to 10, with 10 being the happiest. The least value is 5.

If the fitted line has a y-intercept of 5, the best interpretation of this y-intercept is that the least mood value among the his fellow students is 5.

Intercept actually means beginning, starting point, flat rate e.t.c

Find 50% of 36:<br> Find 25% of 36:<br> Find 75% of 36:
HACTEHA [7]

Answer:

18, 9, 27

Step-by-step explanation:

36 ÷ 2 = 18. Dividing by 2 is the same as multiplying by 50%.

36 ÷ 4 = 9. Dividing by 4 is the same as multiplying by 25%.

Since 25% • 3 = 75%, you can do 9 (from previous) • 3 to get 27.

© y= 2x + 6<br> -3x - 5y= 22<br> Please help with substitution
umka21 [38]

Answer:

[2]    x = -5y - 4

// Plug this in for variable  x  in equation [1]

  [1]    2•(-5y-4) - 5y = 22

  [1]     - 15y = 30

// Solve equation [1] for the variable  y

  [1]    15y = - 30

  [1]    y = - 2

// By now we know this much :

   x = -5y-4

   y = -2

// Use the  y  value to solve for  x

   x = -5(-2)-4 = 6

Solution :

{x,y} = {6,-2}

What is the distance between the two end points (5,6) (-4,-7) round to the nearth two decimal places
garri49 [273]

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have:

(5,\ 6)\to x_1=5,\ y_1=6\\(-4,\ -7)\to x_2=-4,\ y_2=-7

substitute:

d=\sqrt{(-4-5)^2+(-7-6)^2}=\sqrt{(-9)^2+(-13)^2}=\sqrt{81+169}=\sqrt{250}\\\\=\sqrt{25\cdot10}=\sqrt{25}\cdot\sqrt{10}=5\sqrt{10}
