Answer: \frac{17}{20}

Step-by-step explanation:

Given: The total number of caps = 80

The number of green caps = 12

Then , the number of caps which are not green = 80-12=68

If 1 of the 80 caps is selected at random, what is the probability it will NOT be green is given by :-

\text{P(Not green)}=\frac{\text{Caps not green}}{\text{Total caps}}\\\\\Rightarrow\ \text{P(Not green)}=\frac{68}{80}=\frac{17}{20}

Hence, the probability it will NOT be green =\frac{17}{20}

Probabilit is positive events / total number of events

In this case the positive events is to pick a cap that is not green and the total number is 80 (the number of caps).

The number of not green caps is 80 - 12 = 68.

Then the probability the cap selected will not be green is 68 / 80 = 17 / 20

P-24=15

because if argentina has 15 more than south africa then you need to subtract 24-15=p which is pretty much the same things as p-24=15

and if you need to know how many provinces south africa has then 9 provinces should be your answer

(cot^2x - 1)/(csc^2x) = cos2x​
Alex787 [66]

Answer:

Step-by-step explanation:

The idea here is to get the left side simplified down so it is the same as the right side. Consequently, there are 3 identities for cos(2x):

cos(2x)=cos^2x-sin^2x,

cos(2x)=1-2sin^2x, and

cos(2x)=2cos^2x-1

We begin by rewriting the left side in terms of sin and cos, since all the identities deal with sines and cosines and no cotangents or cosecants.  Rewriting gives you:

\frac{\frac{cos^2x}{sin^2x} -\frac{sin^2x}{sin^2x} }{\frac{1}{sin^2x} }

Notice I also wrote the 1 in terms of sin^2(x).

Now we will put the numerator of the bigger fraction over the common denominator:

\frac{\frac{cos^2x-sin^2x}{sin^2x} }{\frac{1}{sin^2x} }

The rule is bring up the lower fraction and flip it to multiply, so that will give us:

\frac{cos^2x-sin^2x}{sin^2x} *\frac{sin^2x}{1}

And canceling out the sin^2 x leaves us with just

cos^2x-sin^2x which is one of our identities.

Answer:

Big Container- $0.30

Medium: $0.33

small: $0.25

Step-by-step explanation:

you divided the number of ounces by the cost

for example- 30/9

small would be the best to by because it is the least cost per ounce

Find an equation of a line that has a slope 7 and passes through the point 3,11
choli [55]
You’re given that m=7 (slope is 7), so setup the slope-intercept form with that info: y = 7x + b.

Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.

11 = 7*3 + b

Notice the only variable left is b, so you’ll find b this way.

11 = 21 + b and then subtract 21 from both sides:

11 - 21 = b

-10 = b

Plug that back into the equation and you have y = 7x -10
