Let y be Amelia's total earnings. Amelia earns $8 per hour. If we let x be the number of hours Amelia works, then the equation representing her earnings would be y=8x
Answer:
30%
Step-by-step explanation:
Think of this as converting a fraction. 28/40 to x/100. You do this because in the situation, 40 is 100 percent of the price. So 28 is <em>x</em> percent of 100.
You multiply 40 by 2.5 to get to 100, so multiply 28 by the same number to get x. 28 * 2.5 = 70.
So 28 is 70 percent of 40. But the question is asking by what percentage it is <em>discounted. </em>If it's now selling for 70%, it has been discounted 30%. So the answer is 30%
Step-by-step explanation:
The only way the answer could be E is if the x² term under the radical is supposed to be t².
f(x) = ∫₄²ˣ √(t² − t) dt
f'(x) = √((2x)² − 2x) (2)
f'(x) = 2√(4x² − 2x)
f'(2) = 2√(4(2)² − 2(2))
f'(2) = 2√12
Given a relative frequency table is made from data in a frequency table.
Frequency Table
G H Total
E 12 11 23
F 14 8 22
Total 26 19 45
Recall that the relative frequency table is obtained from the Frequency table by dividing each entry of the frequency table by the ovarall total of the frequency table.
Thus the relative frequency table of the frequency table above is given by:
Relative Frequency Table
G H Total
E 12/45 = 0.27 = 27% 11/45 = 0.24 = 24% 23/45 = 0.51 = 51%
F 14/45 = 0.31 = 31% 8/45 = 0.18 = 18% 22/45 = 0.49 = 49%
Total 26/45 = 0.58 = 58% 19/45 = 0.42 = 42% 45/45 = 1.00 = 100%
For the given relative frequency table with the missing value y being the value of the relative frequency of E and G.
Therefore, the value of y is 27%
