Probability of picking 2 marbles without looking out of a bag containing 2 red marbles, 2 blue marbles, and 2 white marbles. What is the probability that you will choose a red marble and then a blue marble without replacing the red one?

Answers

Answer 1

Answer: 2/15

Step-by-step explanation:

2 red

2 blue

2 white

6 total

2/6 chance of getting red (1/3)

2/5 chance of getting blue next

2/5*1/3 = 2/15

I think. Sorry if I’m wrong.

Based on the data plotted, choose all that are correct.


A good line of best fit for the data is y = 15x + 55.

The data on the scatter plot shows a negative relationship.

If a student studies for 6 hours, they will receive a grade of about 100.

In general, the longer time spent studying, the higher the student's grade.

Answers

Answer:

- If a student studies for 6 hours, they will receive a grade of about 100.

- In general, the longer time spent studying, the higher the student's grade.

Step-by-step explanation:

Given

See attachment for plot

Required

Select all correct options

First, we determine the equation of best fit.

Pick two corresponding points on the plot

[tex](x_1,y_1) = (2,70)[/tex]

[tex](x_2,y_2) = (4,85)[/tex]

Calculate slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

[tex]m = \frac{85 - 70}{4-2}[/tex]

[tex]m = \frac{15}{2}[/tex]

[tex]m = 7.5[/tex]

The equation is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 7.5(x - 2) + 70[/tex]

[tex]y = 7.5x - 15 + 70[/tex]

[tex]y = 7.5x +55[/tex]

The above represents the line of best fit.

By comparison, (a) is incorrect

We calculate the slope to be:

[tex]m = 7.5[/tex]

Since the slope is positive, then the relationship is positive (b is incorrect)

Also, the positive slope implies that, as x increases, y also increase.

Hence, (d) is correct.

For (c), we substitute 6 for x in the calculated equation of best fit

[tex]y = 7.5x +55[/tex]

[tex]y = 7.5 * 6 + 55[/tex]

[tex]y = 45 + 55[/tex]

[tex]y = 100[/tex]

This shows that (c) is true because 6 hours of study gives a grade of 100

So 2x + x = 90

then, 3x = 90

x= 30

B

Step-by-step explanation:

The diagonals of a rhombus are at right angles to each other, then

∠ 1 = ∠ 2 = ∠ 3 = 90° so

10x = 90 ( divide both sides by 10 )

x = 9

x + y = 90

9 + y = 90 ( subtract 9 from both sides )

y = 81

9z = 90 ( divide both sides by 9 )

z = 10

The amount that x = 53 needs to be to balance the scale.

What is an equation?

The term "equation" refers to a pair of algebraic expressions with the same value and the sign "=" in between.

We have an equation,

221 = x + 68

x = 221 - 68

x = 153

In 153,

1 is in place of hundred 100, 5 is in the place of 10 so, 50.

Therefore, x = 53 is the amount that needs to be to balance the scale.

Answers

Answer:

0.73

Step-by-step explanation:

cost per meter for a roll of paper = total cost / total meter of rolls sold

Supplier x = 18.98 / 25 = 0.76

supplier z = 29.59 / 40 = 0.74
