What is the value of x

On a given school day, the probability that Nick oversleeps is 48% and the probability he has a pop quiz

sasho [114]

Answer:

0.12

Step-by-step explanation:

Independent events are when probability of one event happening doesn't affect the probability of the other event happening.

Also,

In probability "AND" means "multiplication" and "OR" means "addition".

The question asks for probability that Nick oversleeps "AND" has pop quiz. So we need to multiply the individual probabilities (since independent, they have no affect on each other).

P(Nick oversleeps) = 0.48

P(pop quiz) = 0.25

Thus,

P(Nick oversleeps AND pop quiz) = 0.48 * 0.25 = 0.12

Which shows the equation y – 4 = 2(x + 3) written in standard form? A. –2x + y = 10 B. –2x + y = 7 C. y = 2x + 7 D. y = 2x + 10

stiks02 [169]

Answer:

A. $-2x+y=10$

Step-by-step explanation:

Given:

The equation of a line is given as:

$y-4=2(x+3)$

The standard form of an equation of a line is of the form:

$Ax+By=C$ , where, A, B and C are constants.

Now, we have to rearrange the above equation in standard form.

$y-4=2(x+3)$

Distribute 2 to $x+3$ . This gives,

$y-4=2x+6$

Add 4 on both sides. This gives,

$y-4+4=2x+6+4\\y=2x+10$

Now, add -2x on both sides. This gives,

$y-2x=2x-2x+10\\y-2x=10$

Now, rearrange in standard form. This gives,

$-2x+y=10$

Therefore, the standard form is given as $-2x+y=10$

shutvik [7]

Answer: X=5

Step-by-step explanation:

-8=(X+11)/-2

* start by multiplying both sides by -2

16=X+11

*subtract 11 from both sides

miskamm [114]

Answer:

The quantity after t years 40 (0.65)^{\textrm t} millions tons

Step-by-step explanation:

Given as :

The rate of decrease of carbon dioxide each other = 35%

The quantity of carbon dioxide emitted this year = 40 million tons

Let the quantity of carbon dioxide emitted after t year = A millions tons

Now, According to question

The quantity of carbon dioxide emitted after t year = The quantity of carbon dioxide emitted this year ×

Or, A millions tons = 40 millions tons ×
