Answer:

the answer should be 9/14

Step-by-step explanation:

you add them all up then subtract the red for your denominator

then just put the number of white on top for your numerator

Answer:

The correct answer is option C

Step-by-step explanation:

If the red clip is not to be selected , then the sample size shall reduce to

9 + 5\\= 14\\

Now only white clip is to be selected, thus its probability would be

\frac{9}{14} \\

What is the greatest common factor of the numerator and denominator of the rational expression below? 5x-20/x^2-2x-8
OleMash [197]
Factories both equations:
5(x - 4) / (x + 2)(x - 4)

Then take out the common brackets:
5 / x + 2

Minus 2 from both sides:
3 / x

If you are looking for the greatest common factor of the numerator and denominator, the answer would be (x - 4)

A pond has 150 fish and the population decreases by 8% each day. How many days before there are 30 fish
nlexa [21]

Answer:

19 days

Step-by-step explanation:

Given

a = 150 --- initial

r = 8\% -- rate

Required

Days when the fish gets to 30

The function is exponential and as such it follows;

y = ab^x

Where x represents the number of days and y the number of fishes

Because the fishes decreases;

b = 1 - r

So, we have:

b = 1 - 8\%

Express as decimal

b = 1 - 0.08

b = 0.92

In y = ab^x

a =150

y = 30

b = 0.92

So, we have:

30 = 150 * 0.92^x

Divide both sides by 150

0.2 = 0.92^x

Take log of both sides

log(0.2) = log(0.92^x)

Apply law of logarithm

log(0.2) = x\ log(0.92)

Make x the subject

x = \frac{log(0.2)}{log(0.92)}

x = \frac{-0.6990}{-0.0362}

x = 19.309

x \approx 19

<em>Hence, it takes approximately 19 days</em>

Help!<br> math problem step by step please
natta225 [31]

Answer:

2x -y ≥ 4

Step-by-step explanation:

The intercepts of the boundary line are given, so it is convenient to start with the equation of that line in intercept form:

... x/(x-intercept) + y/(y-intercept) = 1

... x/2 + y/(-4) = 1

Multiplying by 4 gives the equation of the line.

... 2x -y = 4

This line divides the plane into two half-planes. The half-plane that is shaded is the one for larger values of x and/or smaller values of y than the ones on the line. So, for some given y, if we increase x we will get a number from our equation above that is greater than 4. Hence, the inequality we want is ...

... 2x -y ≥ 4

We use the ≥ symbol because the line is solid, so part of the solution space.
