Shameel has a flight to catch on Monday morning. His father will give him a ride to the airport. If it rains, the traffic will b
vredina [299]

Answer:

The events rain and Shameel missing his flight are not independent events.

Step-by-step explanation:

Independent events are those events that are not affected by the occurrence (or no occurrence) of other events. These events do not affect the probability of another even taking place.

For example, the events of winning a lottery and being late for work are independent.

If events <em>A</em> and <em>B</em> are independent then:

P(A\cap B)=P(A)\times P(B)

And the conditional probability of <em>B</em> given <em>A</em> is:

P(B|A)=P(B)

Denote the events as follows:

<em>X</em> = Shameel misses his flight

<em>Y</em> = it rains on Monday morning.

The information provided are:

P(X|Y)=0.04\\P(X|Y^{c})=0.03\\P(Y)=0.26

The law of total probability states that:

P(B)=P(B|A)P(A)+P(B|A^{c})P(A^{c})

Use this law to compute the probability of <em>X</em> as follows:

P(X)=P(X|Y)P(Y)+P(X|Y^{c})P(Y^{c})\\=(0.04\times 0.26)+(0.03\times (1-0.26))\\=0.0104+0.0222\\=0.0326\\\approx0.033

If the events <em>X</em> and <em>Y</em> are independent then,

P(X|Y)=P(X)

But the value of P (X) is 0.033.

That is, P(X|Y)\neq P(X).

Thus, the events rain and Shameel missing his flight are not independent events.

If Neil Works 3/4 of an hour on Monday and 6/10 of an hour on Tuesday how much time will she work altogether?
jek_recluse [69]

Answer:

C

Step-by-step explanation:

3/4 + 6/10

Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount

(3/4 * 5/5) + (6/10 * 2/2)=

15/20 + 12/20

Then add

15/20 + 12/20= 27/20

Then finally convert to mixed number

27/20 = 1 7/20

PLZ ANSWER QUICKLY AND THEN PLZ EXPLAIN HOW TO DO IT
Andrews [41]

Hello!

The slope intercept form is y=mx+b, where m is the slope and b is the y-intercept.

First, let's find the y-intercept. This is where the line hits the y-axis. Therefore, it hits at 4 on the y-axis, so our y-intercept is 4.

To find the slope, let's find 2 points on our line. Let's use (0,4) and (2,5). We divide the difference in the y-values by the difference in the x-values as shown below.

\frac{5-1}{2-0} =\frac{4}{2} =2

Therefore, our slope is 2.

Now we plug these values into our equation.

y=2x+4

I hope this helps!
