Answer:
There is 30% probability for the students who score 60 marks in math.
Step-by-step explanation:
The probability of the students who score 60 marks in math is 30%. There is 70% chance that a student will score less than 60 marks in math. The students who score 60 plus in math will score lesser in English.
P=2(l)+2(w)
90=2(4w-5)+2(w)
90= (8w-10)+2w
90=10w-10
10+90=10w-10+10
100=10w
w=10
90=2(4[10]-5)+2(10)
90=2(40-5)+2(10)
90=2(35)+20
90=70+20
90=90
Red =18
blue=48
green=12
orange=?
red/blue =green/orange
so 18/48=12/orange
let orange = X and solve the equation
Answer:
9
Step-by-step explanation:
40 dollars due up front
10 dollars made per sale
5 dollars lost per creation
Realistically speaking she is only making a $5 profit per box she sells;
<em>$5 used up for material cost, $10 made from sales </em><em>-5+10= 5</em>
To pay the $40 dollar for the booth she would need to make 9 sales with her current profit
<em>40/5 = 9</em>
If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.
Divide the number of candy bars (34), by the number each box can hold (5)
Since we cannot have 6.8 boxes, we have to round down to 6.
To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!
