Answer:

34%

Step-by-step explanation:

To find the concentration of the new solution, take the percent time the amount of each of the solutions

40 ml* 25% + 60 ml * 40% = 100 ml* percent

40 * .25 + 60 *.40 = 100 * P

10 + 24 = 100 P

34 = 100 P

Divide each side by 100

34/100 = P

.34 = P

Changing to

34%

I'm not sure how to do this

valentinak56 [21]

Well for 11, it is an inequality, a > sign or < sign with a little underscore mean either "greater than or equal to" or "less then or equal to" so 30> 12+m (>with an underscore) means 30 is greater than or equal to 12+m

Write out the sample space for the given experiment. Use the following letters to indicate each choice: M for mushrooms, A for a

MrMuchimi

Answer: {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}

Step-by-step explanation:

Sample space is a set that contains all the possible outcomes for an event.

For salad:

Choices for extra toppings (mushrooms, olives) =2

Choices for meats (bacon, eggs) =2

Choices for dressings (vinaigrette, honey mustard.)= 2

By Fundamental counting principal .

The number of different salads can be made= (Choices for extra toppings) x (Choices for meats ) x (Choices for dressings)

= 2 x 2 x 2 = 8

All the possible outcomes = (MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)

Required Sample space would be : {(MBV), (MBH) , (MEV) , (MEH) , (OBV), (OBH) , (OEV) , (OEH)}

Which statement describes the function y=ax^n when a=1 and n is odd?

julsineya [31]

ANSWER

B. The graph is symmetric about the origin

EXPLANATION.

The given function is

$y = a {x}^{n}$

When a=1,

$y = {x}^{n}$

Let,

$f(x)= {x}^{n}$

$f(-x)= {( - x)}^{n}$

Since n is odd,

$f(-x)=-{( x)}^{n}$

$\Rightarrow f(-x)=-f(x)$

This implies that, the function

$y={x}^{n}$

is symmetric with respect to origin.

The correct answer is B
