Suppose a group of research proposals was evaluated by a panel of experts to decide whether or not they were worthy of funding.
Ksivusya [100]

Answer:

(a) 0.12 (b) 0.32 (c) 0.56

Step-by-step explanation:

The  sample outcomes are Funded or Unfunded. Total  sample space is given by:

2²= 4

Fund = F

Unfunded =  U

P (F) ist panel = 0.2

P (U) ist panel = 0.8

P (F) 2nd panel = 0.6

P (U) 2nd panel = 0.4

TOTAL SAMPLE SPACE

Ist Panel                Second Panel

F                                  F

F                                  U

U                                 F

U                                 U

(a) Probability of  both panel approval = P (FF)

                                                                =  0.2 x 0.6

                                                                =  0.12

(b) Probability of approval disapproved by both panels = P (UU)

                                                                                            = 0.8 x 0.4

                                                                                            = 0.32

(c) Probability of a worthy disapproval by one panel = P(FU) + P(UF)

                                         = (0.2 x 0.4) +(0.8 x 0.6)

                                         =  0.08 + 0.48

                                         =  0.56

What is the value of x
djyliett [7]

Hey there!


Assuming #1 ….


x + 7x + x = 180°
REWORD

1x + 7x + 1x = 180°

COMBINE the LIKE TERMS

(1x + 7x + 1x) = 180°

8x + 1x = 180°

9x = 180°

DIVIDE 9 to BOTH SIDES

9x/9 = 180/9

CANCEL out: 9/9 because it equal 1

KEEP: 180/9 because it give you the x-value

NEW EQUATION: x = 180/9

SIMPLIFY IT!
x = 20

a line with a slope of -1/9 passes through point (9,-1). What is its equation in slope intercept form
Elena L [17]

Answer:

\huge  \orange{y =  -  \frac{1}{9} x} \\

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

y -  y_1 = m(x -  x_1)

From the question we have

y + 1 =  -  \frac{1}{9} (x - 9) \\ y + 1 =  -  \frac{1}{9} x + 1 \\ y =  -  \frac{1}{9} x + 1 - 1

We have the final answer as

y =  -  \frac{1}{9} x \\

Hope this helps you

How do you solve: 2(b - 5) + 7b-4
Alinara [238K]
2(b-5)+7b-4
Solve 2(b-5) to get 2b-10
Combine your like terms 2b-10+7b-4
Solve 2b+7b to get 9b
Solve -10+(-4) to get -14
So your answer is
9b-14
