(-1/4,-1/2) this is the vertex of that function.
Answer:
Kaely gets 1,680 and Bro gets 1,120
Step-by-step explanation:
First you need to find how may bucks you will receive with 1$
2,800/25
which equals 112
Then multiply 112 by how much Kaely paid and how much Bro paid. Then you have your answer.
Answer:
1.07 (15 + x) = 42.80
Step-by-step explanation:
Given data
CD= $15
Let the cost of the video game be x
The total cost= 15+x
Hence the equivalent expression is
1.07 (15 + x) = 42.80
open bracket
16.05+1.07x= 42.80
42.80-16.05= 1.07x
26.75=1.07x
x= 26.75/1.07
x= 25
Check
7% tax for CD
=0.07*15
=1.05
total =1.05+15
=$16.05
7% tax for Video game
=0.07* 25
=1.75
total =1.75+25
=$26.75
In all
=26.75+16.05
=$42.8

Answer:
0.4833
Step-by-step explanation:
We want GIVEN THAT 200 pages or MORE AND RETURNED ON TIME.
Returned on time
fewer than 200 pages—— 78
200 pages ir more ——116
Returned late
Fewer than 200 pages ——15
Returned late ——31
The first table is returned on time and last row is 200 pages or more, so we take that value "116".
To get probability, we also need the total. We add up all those 4 values:
78 + 116 + 15 + 31 = 240
Thus, probability is = 116/240 = 0.4833
