Answer:
1/4 is your answer
Step-by-step explanation:
290-10=280
280 is one standard deviation below.
All that are above mean is 50%.
One standard deviation below is 34%.
50%+34%=84% all of these bags weigh more than 280 g.
So,
100%-84%=16% should be bags that are less than 280 g.
Answer is b) 16 %.
I am confident that the answer is C. 53.7
Divide the amount she drove by the total amount she needs to drive, them multiply that answer by 100 to make it a percent. This will give you the percentage she drove. To find the percentage she has left,, subtract from 100%.
64 / 160 = 0.4
0.4 * 100 = 40% ( percent she has already driven)
100% - 40% = 60% left.
Answer: See explanation
Step-by-step explanation:
Let Amara money be represented by a
Since Candace has $15 more than Amar. Therefore, Candace money will be = a + 15
Their total money will be 85 and this can be represented in an equation as:
a + (a + 15) = 85.
a + a + 15 = 85
2a + 15 = 85
2a = 85 - 15
2a = 70
a = 35
Amar money = $35
Candace money = $35 + $15 = $50
