Answer: No, he is not correct
The number of combinations is 190
============================================================
Work Shown:
We have 10 shirts, 6 hats, and 4 scarves. This is 10+6+4 = 20 items total.
If we randomly pick out an item, then we have 20 to choose from. After selecting that first item, we have 20-1 = 19 items left to choose from.
So there are 20*19 = 380 different permutations. Order matters with permutations.
Since we aren't worried about order, this means that we've double counted so we have to divide by 2 to fix it.
So there are 380/2 = 190 combinations.
You can use the nCr combination formula 
with n = 20 and r = 2 to get the same result.
Answer:
B. 24 in
Step-by-step explanation:
Add the known sides = 19 in
To solve for the two unknown sides -
Side across from the vertical 3 in is the same, so add another 3 inches to 19 = 22 in
For the side across from the 7in you need to subtract the horizontal sides next to it that you already know.
7 = 3 + 2 +x
x = 2
so add 2 in
22 + 2 = 24in
Answer:
11 < -3t
Step-by-step explanation:
-3⅔ > t
Divide both sides by -3, then reverse the inequality symbol as a result of that.

The terms "linear function" in mathematics apply to two different but related ideas: A polynomial function of degree zero or one that has a straight line as its graph is referred to as a linear function in calculus and related fields.
a) Yes it does, because the graph of their relationship is a Straight line
b) Independent variables are variables whose variation does not depend on another. Number of works does not depend on followers. Therefore, it is independent
C)number of followers depend on the number of locks passing. It is dependent.
D) Slope = (Y₂- Y₁)/(x₂-x₁) = (100-82)/ (3-0) = 18/3 = 6
It represents the increase in number of followers per week,
E) y-intercept is value of y when x=0
y-intercept = 82. It means his initial number of followers
F) Slope-intercept form → y = mx + c m = slope горе C = y-intercept y = no of followers x= weeks.
Y=6x+82
