The class average would be all the test scores added up and divided by the number of scores.
5+5+1+1+1+1+1+0+0+0+0= 15
15/11=1.37
The class average is 1.37
The answer is 0.019 i think
As many were opened during the time period. Jk, I don't know. This is a hard one
I guess that's f(x) = -3x^2+2
Well :
-3x^2+2=0
-3x^2=-2 / : (-3)
x^2= -2/-3
x^2= 2/3 / sqrt
x= +/ - sqrt(2)/sqrt(3)
We got the zero points.
x ~ +/- 0.81
f(0)= -3(0)^2 + 2
f(0)= 2
Mark three points:
(0.81;0)
(-0.81;0)
(0;2)
Connect with parabolic line and ya got a your graph
Answer:
45 total washers
Step-by-step explanation:
Looking at the ratio of 4:11:9:6, we know that there are,
4 nails in each tool box
11 screws in each tool box
9 washers in each tool box
6 brackets in each tool.
Given that there are 5 carpenters with identical tool boxes, we can find the total amount of washers by multiplying the amount of washers in each box with how many carpenters there are.
9 * 5 = 45
