Answer:

The probability that all the graduated had starting salary of $40,000.00 is 0.00525.

Step-by-step explanation:

We are given that at of the Statistics graduates of a University 35%, received a starting salary of $40,000.00.

Also, 5 of them are randomly selected.

The above situation can be represented through Binomial distribution;

P(X=r) = \binom{n}{r}p^{r} (1-p)^{n-r} ; x = 0,1,2,3,.....

where, n = number of trials (samples) taken = 5 graduates

            r = number of success = all 5 had starting salary of $40,000

           p = probability of success which in our question is % of Statistics

                 graduates who received a starting salary of $40,000, i.e; 35%

<em>LET X = Number of graduates who received a starting salary of $40,000.00</em>

<u>So, it means X ~ Binom(n = 5, p = 0.35)</u>

Now, Probability that all the graduated had starting salary of $40,000.00 is given by = P(X = 5)

                   P(X = 5)  =  \binom{5}{5}\times 0.35^{5} \times (1-0.35)^{5-5}

                                  =  1 \times 0.35^{5}  \times 0.65^{0}

                                  =  <u>0.00525</u>

<em />

<em>Hence, the probability that all the graduated had starting salary of $40,000.00 is 0.00525.</em>

Describe the meaning of the y-intercept
neonofarm [45]

Answer:


Step-by-step explanation:

In the equation of a straight line (when the equation is written as "y = mx + b"), the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept (that is, the point where the line crosses the vertical y-axis).

If $60 is the original price and $9 is the amount discount what is 15% of the original price
pantera1 [17]

I'm kinda confused by this question, but, If $60 is the original price, and you want to know what 15% of the original price ($60) is.. It would be $9, the "amount discount".

If this isn't the answer you wanted please tell me and explain the question a bit more to me if you can and I will try my best to help.

Thank you.
