Answer:
1 and -5
Step-by-step explanation:
0 divided by anything is 0
the numerator can equal zero if one factor =0
so
x-1=0
or
x+5=0
solving, we get x=1 or x=-5
So you are given that 45 people in the age range of 18 to 29 who voted make up 10% of the total voters.
And you also know that 30% of the voters are in the age range of 30-49. And you need to find out how many people aged 30-49 voted.
So 10% of the total make up 45 people.
That means for 30% of the total number people, there would be 45 x 3 people, or 135 people. Because 10% x 3 = 30%
So, great job! :D
<span>Using processing software (Excel) or even a decent scientific calculator. You input the values and generate the best fit cubic equation.
For number 1, the equation is
y = 8x10</span>⁻⁵ x³ - 0.0097 x² + 0.374 x + 1.083
where x is the number of years since 1900
y is the pounds cheese consumed
For number 2, the equation is
y = -3x10⁻⁵ x³ + 0.0028 x² + 0.2155 x + 1.7736
For number 3
P(-1) = 18
Answer:
W=2.73
Step-by-step explanation:
Is means equals and of means multiply
W = 7% of 39
Change to decimal form
W = .07 * 39
