An instructor who taught two sections of engineering statistics last term, the first with 20 students and the second with 30, de

Lelechka [254]

Answer:

(a) $P(X=10) = 0.2070$

(b) $P(X\geq 10) = 0.3798$

Step-by-step explanation:

Note that in this problem we have an initial population N = 50, of which 30 fulfill a certain characteristic "m" (belong to the second section). Then, from the population N, a sample of size n = 15 is selected and it is desired to know how many comply with the desired characteristic (second section).

Let X be the number of projects in the second section, then X is a discrete random variable that can be modeled by a hypergeometric distribution.

(a)

Therefore, to answer question (a) we use the following equation presented in the attached image:

Where:

$N = 50\\m = 30\\n = 15\\X = 10$

Then:

$P (X = 10) = \frac{\frac{30!}{10!(30-10)!}\frac{20!}{5!(20-5)!}}{\frac{50!}{15!(50-15)!}}\\\\\\P(X=10) = 0.2070$

(b)

For part (b) we have:

$P(X\geq10) = 1-P(X$

$P(X\geq 10) = 1-0.6202 \\\\P(X\geq 10) = 0.3798$

Triangles FIM and LAK below are similar, with mZF =

Assoli18 [71]

Answer:

LA = 8

Step-by-step explanation:

Since ∆FIM ~ ∆LAK, therefore, the ratio of their corresponding sides are equal.

Thus:

FI/LA = FM/LK

FI = 4

LA = ?

FM = 6

LK = 12

Plug in the values

4/LA = 6/12

4/LA = 1/2

Cross multiply

LA*1 = 2*4

LA = 8

Betty made 3:4 of the baskets she attempted in a basketball game. If she attempted 20 baskets, how many baskets did Betty make?

Elena-2011 [213]

Answer:she would have made 15 baskets

Step-by-step explanation:She would have made 15:20 because since you had 3:4 it’s the same thing with 15:20 she is now going to make a maximum number of 15 baskets
