Answer:
Option C
Step-by-step explanation:
We want to know the percentage of women among people who only prefer exercise.
We have the following information:
Diet Only Exercise Only Diet and Exercise
Men 7 28 15
Women 22 18 10
Then we get the total of people who prefer just exercise.
Now the proportion of women who only prefer exercise is calculated as:
Therefore we must search among the options the table that shows a proportion of 39 for women who prefer only the exercise.
This table is in option C.
C.
Diet Only Exercise Only Diet and Exercise
Men 0.24 0.61 0.60
Women 0.76 0.39 0.40
Answer:
Usually it's in standard form: ax²+bx+c
or vertex form: y=a(x-h)²+k
If you put the graph into a graphing calculator it's going to look like a hill/depression.
Step-by-step explanation:
Standard form ex: 3x²+2x+1
Vertex form ex: y=4(x-1)²-2
104.349540079
7.61 x 104.349540079 = 794.1
Answer:
one glass of milk = 15 carbs
one bar = 14 carbs
Step-by-step explanation:
let 'm' = one glass of milk
let 'b' = one snack bar
system of equations:
2m + 3b = 72
4m + 2b = 88
I used the elimination method and multiplied the 1st equation by -2
-4m - 6b = -144
+ <u>4m + 2b = 88</u>
-4b = -56
b = 14
now solve for 'm'
2m + 3(14) = 72
2m + 42 = 72
2m = 30
m = 15
Answer:
<em>A= 1256</em>
Step-by-step explanation:
<u>The formula for area of a circle is </u>
1. Diameter is DOUBLE of radius, so the diameter must be divided by 2. <em>40/2 = 20. </em>
<em>2. </em>Then, plug in the values into the area formula. <em>A= 3.14</em>
3. Solve.<em> A= 1256</em>. (Remember that 20 squared is <em>20x20</em>)
