No, because there are TWO values of y for a certain value of x

say x=5, then y=2 and y=-2

That does not satisfy the concept of the function.

Answer:

Step-by-step explanation:

To check the given graph of a relation is function or not.

Using graph check for function by vertical line test.

Draw numbers of vertical line. If any of one vertical line intersect the graph at two different points then graph is not a function.

Now check the graph using vertical line.

Draw 3 vertical line. All three vertical line intersect graph at two points.

Please have a look in attachment.

So, The graph of relation is not a function because vertical line test not pass.

You and your friend play a game. You answer 80% of the questions correctly and your friend answers 0.60 of the questions correct

bezimeni [28]

Answer:

Step-by-step explanation:

Assuming both players can answer the same question, the minimum number of questions is the smallest number that when multiplied by either 0.60 or 0.80 yields a whole number.

Let x be the number of questions, solving by trial and error:

$if\ x=2\\x*0.8=1.6\\x*0.6=1.2\\\\if\ x=3\\x*0.8=2.4\\x*0.6=1.8\\\\if\ x=4\\x*0.8=3.2\\x*0.6=2.4\\\\if\ x=5\\x*0.8=4\\x*0.6=3\\\\$

Therefore, the minimum number of questions in the game is 5.

The mean of five numbers is 8. when another number is added the mean is 7. find the number added

sasho [114]

Answer:

$\large \boxed{\sf \ \ 2 \ \ }$

Step-by-step explanation:

Hello,

The mean of five numbers is 8 so we can write

$\dfrac{x_1+x_2+x_3+x_4+x_5}{5}=8$

When another number is added the mean is 7, let s note x the another number we can write

$\dfrac{x_1+x_2+x_3+x_4+x_5+x}{6}=7$

From the first equation we can say

$x_1+x_2+x_3+x_4+x_5=8*5=40$

So the second equation becomes

$\dfrac{x_1+x_2+x_3+x_4+x_5+x}{6}=7\\\\ \dfrac{40+x}{6}=7\\\\40 + x = 6*7=42\\\\ x = 42-40 = 2\\$

The solution is then 2

Hope this helps

What is the volume of a cube with three 1/3 inch sides

boyakko [2]

Answer:

(1/27) in^3

Step-by-step explanation:

"sides" is inappropriate here. You meant "a cube with three edges each 1/3 inch long."

V of cube: V = s^3, where s: side length

Here, V = (1/3 in)^3 = (1/27) in^3

Note: all cubes have 6 (six) sides, including this one with 6 1/3 in sides.
