Answer:

The probability is 0.8944

Step-by-step explanation:

The probability of Z<1.25 in a normal distribution is

P(Z<1.25) = 0.5 + P(Z<1.25)

P(Z<1.25) = 0.5 + 0.3944

P(Z<1.25) = 0.8944

Hence, the probability of randomly selecting a z-score less than z = 1.25 from a normal distribution is 0.8944

Answer:

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number is 24/36 = 2/3

The two events are mutually exclusive

Step-by-step explanation:

we first need to create a table of the sample space from the experiment, the sum of the numbers rolled. Find the attached for a depiction of the possible outcomes.

The probability that the sum of the numbers rolled is either a multiple of 3 or an even number will be given by counting the numbers that are either even or multiples of 3 and then dividing by the number of possible outcomes, 36.

In our case this will be;

24/36 = 2/3

You are in charge of the Annual Powder Puff football game. You designed a t-shirt to sell during the event. A company charges $7
vekshin1
We're looking for C(h), where h is the hundreds of shirts.  The fact that they cost "$500 for each additional 100 t-shirt" tells us the slope is 500.  Knowing that 1 hundred costs 750, we could use point-slope at this point: (C - 750)/(h - 1) = 500C - 750 = 500h - 500C(h) = 500h + 250 We can check that C(1) = 750 and C(2) = 1250, as we expect.  I'll leave it to you to evaluate C(5).

Solve for x<br><br><br><br> Please help
adoni [48]

Step-by-step explanation:

\frac{x}{x + x + 6}  =  \frac{9}{30}

\frac{x}{2x + 6}  =  \frac{9}{30}

30x = 9(2x+6)

30x = 18x+54

30x-18x = 54

12x = 54

x = 54/12

= 27/6
