1/8*5 is 5/40 and you applied it on 1/10 it is going to be 5/50 the denominator has to be the same
Answer:
4/11
Step-by-step explanation:
There are 4 vowels: A, E, A, I
There are 11 characters total, so the probability is 4/11, which is simplified.
Answer:
10 units for the perimeter. 1+4+1+4.
4 square units for the area. Length times width 1x4=4
I can’t help because I can’t see the coordinate plane.
Answer:
Part A:
The vertex : x = - b / 2 a = - 28 : ( - 2 ) = 14
y = f ( 14 ) = - 14² + 28 · 14 - 192 = 196 + 392 - 192 = 4
The vertex is ( 14, 4 ). It means that the maximum hourly profit is $4, and that the shop should sell 14 sodas to reach the maximum.
Part B :
We will solve the quadratic equation:
x 1/2 = ( - 28 +/- sqrt ( 784 - 768 ) ) / ( - 2 )
x 1 = 12, x 2 = 16.
It means that if the shop must sell more than 12 and less then 16 sodas if they want to make a profit ( 13, 14, or 15 ). If they sell 12, or 16 they will brake even.
I think
