Answer:
A. 80
Step-by-step explanation:
Count the first top half and you get 40 and you will know the bottom half is 40
which altogether is 80 or you can count the blocks one by one or count the blocks on the right side count the top blocks by five across.
V= l*w*h
V= 5*4*4
V= 80
Hope this Helps! :)
Have a nice day! :)
Answer:
Let X be the number of times the target is hit. The probability P(X≥1) then equals 1 minus the probability of missing the target three times:
P(X≥1) = 1− (1−P(A)) (1−P(B)) (1−P(C))
= 1−0.4*0.3*0.2
= 0.976
To find the probability P(X≥2) of hitting the target at least twice, you can consider two cases: either two people hit the target and one does not, or all people hit the target. We find:
P(X≥2)=(0.4*0.7*0.8)+(0.6*0.3*0.8)+(0.6*0.7*0.2)+(0.6*0.7*0.8) = 0.788

Answer:
Solving
we get 
Step-by-step explanation:
We need to find solution of 
Solving the inequality:

Multiply 6 with terms inside the bracket

Subtracting 12 on both sides

Adding 4x on both sides

Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >

So, after solving
we get 
So first we want to distribute. (#1)
So, using the distributive property, we can:
5 * 3x - 2y * 5 + 2x + 2 * 2y - 3 * 3x - 3 * 2y
or
15x - 10y + 2x + 4y - 9x - 6y
Now just combine like terms
8x -12y
So for #1 it should be a.
#2: 2x - 3 + 3x - 5
Combine Like Terms:
2x + 3x - 3 - 5
5x - 8
So it should be b.
