Two events are said to be independent when the occurence of one event does not in any way affects the occurence of the other event.

For independent events, the probablilty of event A happening given that event B has happened is given by the probability of event A happening.

i.e. P(a | b) = P(a).

Therefore, given that p(a) = 0.05 and P(b) = 0.65, then p(a | b) = p(a) = 0.05.

I sold 32 posters for a total of 126. And I sold 48 posters for a total of 240. If the relationship between the number of poster
Oksanka [162]

Answer:

The cost per print expressed as a slope is 7.125

Step-by-step explanation:

To calculate the cost per print, let’s envision that we have a graphical representation of cost of posters against the number of posters

We have the cost on the y-axis and the number of posters on the x axis

With the information given in the question, we shall be having two data points

Point 1 = (32,126)

point 2 = (48,240)

Now to find the slope of the line which is cost per print, we make use of both points in the slope equation.

Mathematically, slope m will be

m = y2-y1/x2-x1

Thus, we have;

m = (240-126)/(48-32)

m = 114/16

m = 7.125

The cost per print expressed as a slope is 7.125

WRITE 0,000003 56 IN SCIENTIFIC NOTATION ​
Elanso [62]

Answer:

3.56X10^-6

Step-by-step explanation:

In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:

1. The numerical coefficient.

2. Number of times we move the decimal point. It will be the exponent with the base of 10.

3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.

Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.
