If you decrease something by 4 percent,
you are keeping (100% - 4%) or 96% of the original
so multiply by the original amount by 96 percent or .96
If you have 100 pennies, and you give 4 away ( 4 percent decrease), you still have 96 pennies. You are keeping 96 percent of what you started with. This works no matter how much you start with.
Example:
you have 40 dollars
4% decrease
40 * .04 = 1.6 take this away
40 - 1.6 = 38.4 left
you keep 96 percent
40 * .96 = 38.4 left
Answer: 7 is 1/8, 8 is 2/8 or 1/4
Step-by-step explanation:
<span> 110y+10=340
Subtract 10 from both sides
110y=330
Divide by 110 to get variable on its own
</span>110y/110=330/110
y=3
The answer will be the last one as it equals 4x + 3. this means that the equation will be parallel and does not have a solution.
<u>Answer:</u>
The correct answer option is 43%.
<u>Step-by-step explanation:</u>
We are given that 70% of students have blue eyes, 45% have dark hair, and 30% have blue eyes and dark hair.
We are to find the probability of a student getting selected will have dark hair with blue eyes.
P(D|B) = P(D∩B) / P(B)
Substituting the given values in it to get:
P(D|B) = 0.3 / 0.7 = 0.428
Rounding it to the nearest whole percent we get:
0.428 × 100 = 42.8% ≈ 43%
