Ok done. Thank to me :>
Answer:
Step-by-step explanation:
The odds for 4 heads = (1/2)^4 = 1/16..
So the odds against is 1 - 1/16 = 15/16.
1000/7 = <span>142.857142857
Because this is not an even number we take "142", then times it by 7 teachers.
142*7= 994
1000 - 994 = 6 Pencils left</span>
Answer:
$6.48
Step-by-step explanation:
First, let's find the discount.
1.60 * 0.1 = $0.16 (the discount)
Second, subtract the discount to the original price.
1.60 - 0.16 = $1.44 (price after discount was applied)
Third, multiply to 4 1/2 to find how much it will cost.
1.44 * 4.5 = $6.48 (price of 4 1/2 pounds of apples with discount applied)
Its just a matter of subbing
-7x - 4y = 6....subbing in (-2,2)...x = -2 and y = 2
-7(-2) - 4(2) = 6
14 - 8 = 6
6 = 6 (correct)
so ur solution is (-2,2)
