In a jar of marbles 9 out of 15 marbles are purple. Of there are 400 marbles in the jar, how many of th are not purple?
kramer

Answer:

C) 160

Step-by-step explanation:

Set up a proportion:

\frac{9}{15} = \frac{x}{400}

Cross multiply and solve for x:

15x = 3600

x = 240

This means in 400 marbles, 240 are purple.

To find how many are not purple, subtract 240 from 400:

400 - 240

= 160 marbles

So, 160 marbles are not purple

What is the length of ?<br><br> 3 ft<br> 4 ft<br> 9 ft<br> 18 ft
zmey [24]
Answer:
AC = 18 ft

Explanation:
There is a geometric theorem that states that:
" In a triangle, the line joining two midpoints of two sides is parallel to the third side and equals have its length"

Now, let's check the given triangle:
M is the midpoint of AB
N is the midpoint of BC

Based on the above theorem:
MN will be parallel to AC
and
length of MN = (1/2) * length of AC

We are given that:
length of MN = 9 ft
Therefore:
9 = (1/2) * length of AC
length of AC = 2 * 9 = 18 ft

Hope this jhelps :)

Solve the math problem
VladimirAG [237]

Answer:

<u>Explanatory variable</u> (independent variable)

  • The variable that affects the other variable.
  • Drawn along the horizontal axis.

<u>Response variable</u> (dependent variable)

  • The variable that is being affected.  
  • Drawn up the vertical axis.

(a) As the class wondered if they could <em>predict the father's height</em>, when they<em> know the son's height</em>

Explanatory variable = son's height

Response variable = father's height

(even though this is contrary to real-life, where the father's height would be used to predict the son's height)

(b) **see first attachment**

(c)  The association is positive since the father's height increases as the son's height increases.

(d)  **see second attachment**

Outlier = Paul  (64.5, 73)

This point is far away from the majority of points on the scatter plot.

If we add a regression line to the scatter plot, we can see that this data point is the farthest from the regression line.
