Okay! Let's write out all the numbers:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
Now, let's bold (or you can circle them... or do really anything to them as long as they are standing out to you) the even numbers (remember all even numbers are divisible by 2)
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
Now let's list all the ones we highlighted:
2
4
6
8
10
12
14
Count up how many numbers that is.
You should get 7.
So, our answer is 7 out of 15 numbers.
Or as a fraction:
7/15 is our answer.
Note: A probability is the number of chances something has to happen out of the total number of chances. So in this case the number of even numbers out of the total number of numbers. You can apply this to any probability problem. Hope this helps!

Answer:
156
Step-by-step explanation:
209x18.50=3866.5
5700-3866.5=1833.5
1833.5÷11.75=156.04
Check the picture below.
includes 2, notice, it doesn't go below 2 over the y-axis, and then it keeps on going up. So, the range is from +2 onwards.
Answer:
134 sneakers and 66 sandals
Step-by-step explanation:
Sneakers= x, sandals= y
Profit rate:
- sneakers: (10-2)/8= 25%
- sandals: (17-14)/14= 21.4%
Sneakers are more profitable, so it should be maximized.
Cost:
8x+14y≤2000
x+y≤200
if we assume the maximum of 200 shoes stocked, then:
x= 200-y
8(200-y)+14y ≤ 2000
1600 - 8y +14y ≤ 2000
6y≤400
y≤66 and x=134 is the best option
I assume you mean
2 tonnes of sand
at £75.00 per tonne
20 bags of cement
at £6.70 per bag
350 bricks at 45p each
If so, then
2 tonnes of sand
at £75.00 per tonne = 2 * £75.00 = £150.00
20 bags of cement
at £6.70 per bag = 20 * £6.70 = £134.00
350 bricks at 45p each = 350 * £0.45 = £157.50
Add the three amounts
£150.00 + £134.00 + £157.50 = £441.50
Answer: 441.50
