The ratio of boys to girls would be 
since you can divide both 14 and 21 by 7, the simplified form would be 
.
The answer is 2 to 3.
Answer:
Two ways you can group them is:
(4+7)+2
4+(7+2)
They will both give you the same answer of 13.
(4+7)+2 4+(7+2)
11+2= 13 4+9= 13
Answer:
1) D.208
2) C.112
Step-by-step explanation:
so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together
l= length
w=width
a=area
4*8=32
4*8=32
6*4=24
6*4=24
6*8=48
6*8=48
48+48+24+24+32+32=208
208
for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.
for the triangles you're gonna wanna use the equation 1/2b*h=a
b= base
h=height
a=area
7*4=28
7*4=28
7*4=28
7*4=28
28*4=112
Answer:
45 degrees
Step-by-step explanation:
Answer:
Option C) a positive correlation.
Step-by-step explanation:
We are given the following in the question:
" People who tend to score low on one variable tend to score low on another variable."
Correlation:
- Correlation is a technique that help us to find or define a linear relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity or decrease in one quantity leads to decrease in another quantity.
- A negative correlation means with increase in one quantity the other quantity decreases.
- +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
Since, for the given case with decrease in one variable other also decreases, thus, it is an example of positive correlation. Thus, the correlation coefficient cannot be less than or equal to zero.
Thus, the correct answer is
Option C) a positive correlation.
