Answer:

25%

Step-by-step explanation:

This question is about conditional probability. Let's say that the probability of raining on Saturday is X=true and the probability of raining on Sunday is Y=true. There is a 15% it will rain on both Saturday and Sunday, to put into the equation it will be:

P(X= true ∩ Y = true) = P(X = true) * P(Y = true)= 0.15

There is a 60% chance of rain on Saturday, mean the equation is

P(X = true) = 0.6

The question is asking for the chance of rain on Sunday or P(Y = true). If we substitute the second equation to first, it will be:

P(X = true) * P(Y = true)= 0.15

0.6* P(Y = true)= 0.15

P(Y = true)= 0.15/0.6

P(Y = true)= 0.25 = 25%

P = nc - e and p is 4520 and n is 3000 and e is 700 what is the value of c

adoni [48]

Answer:

c= 1.74

Step-by-step explanation:

4520 = 3000(c)-700

4520=3000c-700

+700 +700

5220=3000c

c=1.74

to check to see if this is right you would do this:

4520=3000(1.74)-700

4520=5220-700

4520=4520

I am organized an ocean cleanup and we collected a total of 25 pounds of garbage 16 pounds of the garbage consisted of plastic w

Makovka662 [10]

Answer: 64% of garbage was plastic over there when he was collected garbage.

Step-by-step explanation:

Since we have given that

Total amount of garbage collected by them = 25 pounds

Total amount of garbage which consisted of plastic = 16 pounds

Percent of the garbage was garbage is given by

$\frac{ plastic}{total}\times 100$

$=\frac{16}{25}\times 100\\\\=16\times 4\\\\=64$

Hence, 64% of garbage was plastic over there when he was collected garbage.

What is the inverse and restricted domain of the equation 8x^2-3

kari74 [83]

Answer: $\bold{y=\pm \dfrac{\sqrt{2(x+3)}}{4},\qquad x\neq -3}$

<u>Step-by-step explanation:</u>

y = 8x² - 3 (Restriction: none - x is All Real Numbers)

The inverse is when you swap the x's and y's and then solve for y

x = 8y² - 3 <em>swapped the x and y</em>

x + 3 = 8y² <em>added 3 to both sides</em>

$\dfrac{x+3}{8}=y^2$ <em>divided both sides by 8</em>

$\sqrt{\dfrac{x+3}{8}}=\sqrt{y^2}$ <em>square rooted both sides</em>

$\pm \sqrt{\dfrac{x+3}{8}}=y$ <em>simplified</em>

$\pm \sqrt{\dfrac{x+3}{8}\bigg(\dfrac{2}{2}\bigg)}=y$ rationalized the denominator

$\pm \sqrt{\dfrac{2(x+3)}{16}}=y$ <em>simplified</em>

$\pm \dfrac{\sqrt{2(x+3)}}{4}=y$ <em>simplified</em>

<u>Restriction:</u>

The radical <em>(inside the square root sign)</em> cannot be negative

→ 2(x + 3) ≥ 0

x + 3 ≥ 0 <em>divided both sides by 2</em>

x ≥ -3 <em>subtracted 3 from both sides</em>
