To find this, multiply both the numerator and denominator by the same number. For example, 8 x 8 =64, and 10 x 8=80, so 64/80 would be an example of an equivalent ratio. Others could be 16/20 or 48/60. Hope this helps.

There are 4 blueberry, 6 raisins, and 2 plain bagels in a bag. Mike randomly selects two bagels without replacing the first bage

rodikova [14]

Answer:

The probability that he selects a raisin bagel and then a plain bagel is $\frac1{11}$ .

Step-by-step explanation:

Probability:

The ratio of the number of outcomes of favorable event to total number of all possible outcomes is called probability of the favorable event.

$Probability=\frac{\textrm{The number of favorable outcomes}}{\textrm{Total number of all possible}}$

Given that, there are 4 blueberry, 6 raisins and 2 plain bangles in a bag.

Total number of bangles= (4+6+2)

= 12

The probability that he selects a raisin

$=\frac{\textrm{Number of raisin bangles}}{\textrm{Total number of bangles}}$

$=\frac{6}{12}$

$=\frac12$

Total number of remaining bagels is =(12-1)=11

After selecting a raisin bagel,the probability that he selects a plain bangle is

$=\frac{\textrm{Number of plain bangles}}{\textrm{Total number of bangles}}$

$=\frac{2}{11}$

Selecting of a raisin bangle and a plain bangle are both independent event.

The probability that he selects a raisin bagel and then a plain bagel is

$=\frac{1}2\times\frac{2}{11}$

$=\frac1{11}$

find four consecutive even integers such that 2 times the sum of the first and second is 14 more than 3 times the fourth.

motikmotik

Let the first integer be x, then:-

2 (x + x+ 2) = 3(x + 6) + 14

4x + 4 = 3x + 18 + 14
x = 18 + 14 - 4 = 28

the four integers are 28,30,32 and 34.

Is the equation y=(x-2)³ a function?

lesya [120]

Answer:

Yes, it is a function.

Step-by-step explanation:

A relation is a function if it passes the VLT (Vertical Line Test).

When graphed, it kind of looks like a combination between a "U" and "V" shape, meaning it passes the Vertical Line Test.
