Answer:
1. 14
2. 2.75
3. 7.25
4. 6.5
Step-by-step explanation:
1. You just make a dot plot and count the amount of dots there are.
2. You go to your dot plot and see the smallest amount and you get your answer.
3. Same thing as the smallest amount, except you just have to find the greatest amount.
4. You just find which number appears the most on the dot plot, and bam you got your answer.
Step-by-step explanation:
2(8)+2(8)=64
2(3+8)+(2+8) =64
2(3(8))2(8)=64
2(3+8)2(8)=64
Answer:
0.2
Step-by-step explanation:
33 1/3 is 33.333333333333
Divide by 100 because it is a percentage. You'll get .33333. Then multiply your 1.2, you should get 0.4
33 x 1/3 = 33.3333
33.3333/100 = .3333333
.33333333 x 1.2 = 0.4
We want 50% of that, so just halve it.
0.4 /2 = 0.2
Step-by-step explanation:
the function actually is
y = 40(x - 1) + 70 = 40x - 40 + 70 = 40x + 30
still, the slope (the factor of x) is 40.
that means y (the cost) increases by 40 for every additional hour (x increases by 1).
so, the rate of change (slope) is 40/1 = $40 per hour.
