A bag contains 5 white marbles and 30 blue marbles. If a representative sample contains 2 white ​marbles, then how many blue marbles would you expect it to​ contain? Explain. Because the ratio of white marbles to blue marbles is ▼ 6:5 6:1 5:6 1:6 in the​ population, the expected number of blue marbles is nothing times the number of white marbles in the representative sample. There should be nothing blue marbles.

Answers

Answer 1

Answer:

6:1

Step-by-step explanation:

Answer 2

Answer: 10

Step-by-step explanation:

The expected number of blue marbles in the representative sample is 10. This is because the ratio of white marbles to blue marbles in the population is 5:6, so for every 5 white marbles there are 6 blue marbles. Since the representative sample contains 2 white marbles, the expected number of blue marbles should be 6 times the number of white marbles, or 6 x 2 = 10.

A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees and totaled $411

Answers

Answer:

Cost of 1 bushes = a = $9

Cost of 1 tree = b = $73.5

Step-by-step explanation:

Given:

13 bushes and 4 trees cost = $411

Missing;

6 bushes and 2 trees cost = $201

Find:

Value of bushes and tree

Computation:

Cost of 1 bushes = a

Cost of 1 tree = b

So,

13a + 4b = 411 ...........eq1

6a + 2b = 201 ................eq2

From Eq1 and Eq2

Cost of 1 bushes = a = $9

From eq 1

13a + 4b = 411

13(9) + 4b = 411

Cost of 1 tree = b = $73.5

The function f(x) = 34,000(1.05)* can be used to
determine Noah's cost of living in Houston over time.
What does the 1.05 represent?
A The cost of living will increase by approximately 1% each year
B The cost of living will decrease by approximately 1% each year
C The cost of living will increase by approximately 5% each year
D The cost of living will decrease by approximately 5% each year

Answers

9514 1404 393

Answer:

  C  The cost of living will increase by approximately 5% each year

Step-by-step explanation:

If we assume your function is ...

  [tex]f(x)=34000(1.05)^x\qquad\text{x is years}[/tex]

Then the growth factor 1.05 represents a growth rate of 1.05 -1 = .05 = 5% per year. The positive growth rate means the cost of living is increasing.

Noah's cost of living is increasing about 5% per year.

10.3

Step-by-step explanation:

The question is asking to find the length of the hypotenuse of the triangle. This requires us to use the Pythagorean theorem. The legs measure 9 and 5, so we use these to solve for c.

[tex]9^{2} + 5^{2} =c^{2} \\81 + 25 = c^{2} \\106 = c^{2} \\[/tex]                            

We find the square root of both sides to find the value of c.

Find the mean and the standard deviation of the data set {5, 8, 1, 2, 10}.

5 + 8 + 1 + 2 + 10  =  26 (divided by) 5 = 5.2

         

The mean and the standard deviation of the data set is 5.2 and 3.429.

What is Arithmetic Mean?

The arithmetic mean is the average of a sum of numbers that shows the centre tendency of the numbers' position. It is frequently used as a parameter in statistical distributions or as a result of an experiment or a survey to summarise the findings.

We have,

Data:  {5, 8, 1, 2, 10}.

So, the mean of data

= (5+ 8 + 1 + 2 +10)/ 5

= 5.2

Then, the Value of Deviations

-0.2, 2.8, -4.2, -3.2, 4.8

So, the variance is

= (0.04 + 7.84 + 17.64 + 10.24 + 23.04) / 5

= 11.76

And, Standard deviation is

= 3.429
