Answer:
4838 total number of voters
Step-by-step explanation:
In a whole circle there 360°, in a straight line theres 180°.
180-110=70 first to break it down to find the degrees of women.
180+70=250° for women.
250°=3360
we need to find 110° of men
25°=336
times 4
100°=1344
divide by 10
10°=134.4 round down 134
1344+134=1478
3360+1478=4838
X/7-3=6
X/7=6+3
X/7=9
7x9=63
63/7-3=6
9-3=6
I would say choice “C”
Hello!
A function is that y only has 1 solution for every x
-3x + 8 = y is a function because it only has one y value for every x
y = x^2 + 3 is a function because it has only one y value for every x
y^2 = x is not a function because it has two y values for x = 4
Hope this helps!
In 371 ways Mrs. Sullivan choose two students from 27 to help put away calculators at the end of class
Step-by-step explanation:
let us assume that Mrs.Sullivan wants to choose 2 students from a group of 27 students
So ,in the first choice we have 27 students
In the second choice we have 26 choices
So Mrs.Sullivan has = 27 × 26 = 702 ways
But each group repeated twice,in order to avoid that we will divide the answer by 2
so we will write
= 702 ÷ 2 =<u> 351 ways</u>
<u>This method of calculation is called Combination</u>
