Answer:

Probability Mass Function:

x: 0 1 2 3

P(x): 0.000064 0.004608 0.115902 0.884736

Step-by-step explanation:

We are given the following information:

We treat correct classification as a success.

P(correct classification) = 0.96

Then the number of classification follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 3 and x = 0, 1, 2, 3

We have to evaluate:

$P(x = 0)\\= \binom{3}{0}(0.96)^0(1-0.96)^3\\=0.000064$

$P(x = 1)\\= \binom{3}{1}(0.96)^1(1-0.96)^2\\=0.004608$

$P(x = 2)\\= \binom{3}{2}(0.96)^2(1-0.96)^1\\=0.115902$

$P(x = 3)\\= \binom{3}{3}(0.96)^3(1-0.96)^0\\=0.884736$

PMF:

x: 0 1 2 3

P(x): 0.000064 0.004608 0.115902 0.884736

20

Step-by-step explanation:

1532/36 = 42.5556

round that down to 42

42 * 36 = 1512

1532 - 1512 = 20

Line l is tangent to the graph of y= x - x²/500 at point Q & it crosses the y-axis at (0, 20)

insens350 [35]

A. Equation of line l: y = mx + 20 where m = y' = 1- (1/250)x

At the point Q, The equation of the line equals the equation of the parabola.

So (1-x/250)x + 20 = x - x^2/500

20 = x^2/250 - x^2/500 = x^2/500
x = sqrt(20*500) = 100ft

B. m = 1 - 100/250 = 3/5.

<span>Equation of line L is y = 3/5x + 20
</span>
C) If a spotlight is located at the x intercept of line L (-33 1/3,0), its light will go only above line L past the point where line L is tangent to the hill at (100,80) because the hill blocks the light below the tangent line.

<span>The highest point on the equation of y = x - x²/500 is at (250,125), so a tree 50 feet tall at that location would reach up to (250,175). The tangent line goes through (250,170), so the top 5 feet of the tree would be above the tangent line, in the glow of the spotlight.

Mrs. Cho is bringing cans and bottles to a recycling center. For a type A can, she gets 5 cents. For type B can, she gets 10 cen

Grace [21]

Answer:

One possible solution be -

Mrs. Cho is brings type A cans = 10

Mrs. Cho is brings type B cans = 3

Step-by-step explanation:

Let us assume

Mrs. Cho is brings type A cans = x

Mrs. Cho is brings type B cans = y

As given,

For a type A can, she gets 5 cents and For type B can, she gets 10 cents

As we have x Type A cans and y Type B cans

And she has redeemed no more than 95 cents

⇒5x + 10y ≤ 95 .......(1)

Also given,

She has redeemed at least 11 cans

⇒ x + y ≥ 11 ........(2)

∴ we get

x + y ≥ 11

5x + 10y ≤ 95

By applying graphical method , we get

The equations become

5x + 10y = 95 .......(1)

x + y = 11 ........(2)

Table for equation (1) -

x y

0 9.5

19 0

Table for equation (2) -

x y

0 11

11 0

The two lines intersect at point (3, 8)

So the possible combinations are in the shaded portion which is covered by both the lines.

One possible combination is ( 10, 3) which lies in the shaded region.

So,

Mrs. Cho is brings type A cans = x = 10

Mrs. Cho is brings type B cans = y = 3
