Answer: 305 people
Step-by-step explanation:
The total number of people sampled is:
= 71 + 22 + 27 + 83
= 209
Out of this 209, the number of people who prefer Vanilla and cookie dough ice cream is:
= 71 + 27
= 98 people
In a sample of 209 people, 98 people would prefer either vanilla or cookie dough. In 650 people, that number would therefore be:
= 98/ 209 * 650
= 305 people
Step-by-step explanation:
By solving, I am assuming that you want to find the zeros.
So to find what x equals, first, you factor out an x.
3x² - 4x = 0
x(3x - 4) = 0
Here, you can separate the equation into two different equations to solve for x.
- <em>3x - 4 = 0</em> and <em>x = 0</em>
- x =
and x = 0
Those are your zeros.
And for its graph, you can always look to an online graphing calculator. I used Desmos.
U have an equilateral triangle where all angles are equal to 60 degrees
7x + 4 = 60
7x = 60 - 4
7x = 56
x = 56/7
x = 8 <==
and if u wanted to find y, u would set it up like this : 8y + 12 = 60 and solve for y
Answer:
B. -4
Step-by-step explanation:
We want to find x such that f(x)=18.
We need to therefore solve 9x+54=18 forx.
9x+54=18
Divide both sides by 9:
(9x+54)/9=18/9
9x/9+54/9=18/9
Simplify:
x+6=2
Subtract 6 on both sides:
x=2-6
Simplify
x=-4.
So f(-4) should have value 18.
Let's check.
f(x)=9x+54
f(-4)=9(-4)+54
f(-4)=-36+54
f(-4)=18
So the answer is B.
