Find the probability distribution for the following function:P(x) =for x = 4, 6, and 8

P(3) = 2, P(5) = 3, P(7) = 4

P(3) = 9, P(5) = 10, P(7) = 11

P(3) = 1, P(5) = 2, P(7) = 3

P(4) = 3, P(6) = 4, P(8) = 5

Answers

Hello,
sorry, I haven't understood the question.

ANSWER D:
the probability must be defined for 4,6,8
P(4)=3
P(6)=4
P(8)=5
But probability must be <1

==> P(4)=3/12, P(6)=4/12 and P(8)=5/12

So 3/12+4/12+5/12=12/12=1

Name Score Julia 650 Andrew 550 Jason 380 Cathy 720 Jessica 710 Robert 550 The table gives the scores of 6 students from a class of 25 in a competitive exam. The point estimate of the mean score for the students is . (Round off your answer to the nearest tenth.)

Answers

Answer:

The mean score for the students is 593.33.

Step-by-step explanation:

The table gives the scores of 6 students from a class of 25 in a competitive exam.

Name : Julia Andrew Jason Cathy Jessica Robert

Score : 650 550 380 720 710 550

Mean = Sum of the data values / Total number of data values

Mean = ( 650 + 550 + 380 + 720 + 710 + 550 ) ÷ 6

= 3560 ÷ 6 =593.33

The mean score for the students is 593.33.

(650 + 550 + 380 + 720 + 710 + 550) / 6 = 3560/6 = 593.3

A rectangle’s width is 2 meters shorter than its length, l. Its area is 168 square meters. Which equation can be used to find the length of the rectangle?l(l – 2) = 168
l(l + 2) = 168
2l 2 = 168
1/2l 2 = 168

Answers

Since area of a triangle is;
l*w=area
l(l-2)=168

Find the slope of the line that contains these two points.
(2, -5) and (7, -10)

Answers

$\sf Slope= (y_2-y_1)/(x_2-x_1)$

Where $\sf (x_1,y_1), (x_2,y_2)$ are the two points.

So

$\sf Slope = ( -10-(-5))/(7-2)=(-10+5)/(7-2)=(-5)/(5)=-1$

So the slope of (2,-5) and (7,-10) was $\boxed{ -1}$

m= $(y1-y2)/(x1-x2)$ = $(-5-(-10))/(2-7)$ = $(5)/(-5) =-1$
Answer: slope is -1

72 is 25% of what number?

A. 35
B. 18
C. 180
D. 288

Answers

72 is 25% of 288

Convert the percentage into a decimal:
$(25)/(100) = 0.25$

Divide 72 over the decimal:
$(72)/(0.25) = 288$

It is a quarter of d 72*2=144
144*2=288
