Answer:

  • 5/9

Step-by-step explanation:

There are 4 blue, 5 red and total of 9 marbles.

<u>If two marbles are taken and we are looking for exactly one red, then it is:</u>

  • red, then blue or blue, then red

<u>Find the probability of each case:</u>

  • P(r, b) = 5/9*4/8 = 5/18
  • P(b, r) = 4/9*5/8 = 5/18

<u>Probability of exactly one red:</u>

  • P = 5/18*2 = 5/9

What is the following sum? 40 POINTS
7nadin3 [17]

Answer:

option 1

Step-by-step explanation:

cube root of 125 = 5

cube root of 27 = 3

5+3 = 8

now take x^10 =cube root of x^(3+3+3+1)

cube root of x^10 = x^(1+1+1)+*cube root of x

cube root of y^13 = cube root of y^(3+3+3+3+1)

= y^4*cube root of y

so answer is opt 1

-79 = 7x + 3(4x - 1)<br><br> Help
Dmitry [639]

Answer:

x = - 4

Step-by-step explanation:

-79 = 7x + 3(4x - 1)

-79 = 7x + 12x - 3                      Distribute 3 to the paranthesis

-79 = 19x - 3                              Add like terms

-76 = 19x                                   Add 3 to both sides

- 4 = x                                          Divide 19 to both sides

Determine u-x and o-x from the given parameters of the population and the sample.size. round the answer to the nearest thousandt
andriy [413]

The u-x and o-x from the given parameters of the population and the sample size will be u =28 and standard deviation is 5.

<h3>How to calculate the values?</h3>

From the information given about the population and sample mean, the values include:

u=27 o=5 n=14

The standard deviation will be:

= 5/✓14

= 5/3.74

= 1.34

Therefore, u-x and o-x from the given parameters of the population and the sample size will be u =28 and standard deviation is 1.34.
