You have a jar of marbles with 7 red, 12 blue, 6 yellow, and 9 white. What is the probability of selecting a marble that is not

Schach [20]

Answer:

The probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102

Step-by-step explanation:

Number of red marbles = 7

Number of blue marbles = 12

Number of yellow marbles = 6

Number of white marbles = 9

Total marbles = 7+12+6+9=34

Probability of selecting red marble = $\frac{7}{34}$

Probability of selecting no red marble = $1-\frac{7}{34}=\frac{27}{34}$

Now replacing it one marble is drawn again

So, Probability of getting white marble $=\frac{9}{34}$

So,the probability of selecting a marble that is not red, replacing it and then one that is white = $\frac{27}{34} \times \frac{9}{34}=0.2102$

Hence the probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102

Please help!!!!! this worksheet is due by the end of class

Answer:

Slope: 6

y-intercept: 8

x-intercept: -4/3

Step-by-step explanation:

Isolate the y. Note the equal sign, what you do to one side, you do to the other. First, divide 2 from both sides:

(2y - 6x - 8)/2 = (0)/2

y - 6x - 8 = 0

Isolate the variable, y. Add 6x and 8 to both sides:

y -6x (+6x) - 8 (+8) = 0 (+6x) (+8)

y = 0 + 6x + 8

y = 6x + 8

The slope intercept form is: y = mx + b, in which m = slope, and b = y-intercept.

Slope: 6

y-intercept: 8

To find the x-intercept, plug in 0 for y in the equation:

y = 6x + 8

0 = 6x + 8

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 8 from both sides:

0 (-8) = 6x + 8 (-8)

-8 = 6x

Isolate the variable, x. Divide 6 from both sides:

(-8)/6 = (6x)/6

x = -8/6

x = -4/3

x-intercept: -4/3

Use the graph below to determine a1 and d for the sequence. graphed sequence showing point 1, 17, point 2, 14, point 3, 11, poin

Leona [35]

Answer:

So the Correct option is

$a_{1}=17;\ d=-3$

Step-by-step explanation:

Given:

Let

A(1, 17),

B(2, 14),

C(3, 11),

D(4, 8),

E(5, 5), and

F(6, 2) be the Points For The Sequence

Solution:

For the First Term

A( 1, 17 )

$a_{1}=17$

For the second Term

B(2, 14),

$a_{2}=14$

For the third Term

C(3, 11),

$a_{3}=11$

For the fourth Term

D(4, 8),

$a_{4}=8$

For the fifthTerm

E(5, 5)

$a_{5}=5$

For the sixth Term

F( 6, 2 )

$a_{6}=2$

Now Common Difference 'd' is given as

$d=a_{2}-a_{1}=14-17=-3\\\therefore d=-3$

So the Correct option is

$a_{1}=17;\ d=-3$
