Question 1 The solution to 5 - 3x > 35 is either r > -10 or -10 > 2. Which solution is correct? Explain how you know. Edit View Insert Format Format Tools Table 12pt Paragraph BI U AY 2 T?

Answers

Answer:

x < -10

Step-by-step explanation:

Given the inequality 5 - 3x > 35

Subtract 5 from both sides

5 - 3x - 5> 35 -5

-3x > 30

Divide both sides by -3

-3x/-3 < 30/-3

x < -10 (note the change is sign)

hence the correct solution is x < -10

What is the median of the following numbers?
3.31,37,56, 61,57,62

Answers

Answer:

The answer might be 56 because the median is the middle of it

we can start by putting them in order from least to greatest, which is 3.31,31,37,56,57,61,62. sorry if it doesn’t make sense, but basically just need to count from either side until you get to the middle and it’s even on each side, like 3.31,37-56,57-61,62 then find the middle in 56 and 57, which is 56.5

Suppose that Violet is conducting a study to determine whether there is a relationship between the time a person spends running and the number of calories that he or she burns. She selects a random sample of 40 runners between the ages of 18 and 24 and records the time that each person ran and the number of calories that each person was able to burn while running. At the end of her study, she finds that people who were able to run for longer times burned more calories.
(a) What type of study is this? Briefly explain
(i) Experiment
(ii) Observational study
(iii) Survey
(b) What is the explanatory variable? Is it categorical or quantitative?
(c) What is the response variable? Is it categorical or quantitative?
(d) Which of the following is a potential lurking variable in this study? Defend your selection (i.e. explain why it is a lurking variable).

Answers

Answer:

= 1.156 × 10^9

(scientific notation)

= 1.156e9

(scientific e notation)

= 1.156 × 10^9

(engineering notation)

(billion; prefix giga- (G))

= 1156000000

Step-by-step explanation:

Simply subtract A from B = 1,156,000,000 and convert the answer to scientific notation.

Answer:

D. 1.156 times 10^9

First we subtract the difference,

1,300,000,000 - 144,000,000 = 1156000000

Next, we find the number 1156000000 written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 115,600,000

New Number: 1.15600000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 1 5 6 0 0 0 0 0

Decimal Count: 1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.156 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.156 x 108

Step 4

Check your work:

108 = 100,000,000 x 1.156 = 115,600,000

Thus, 115,600,000 written in scientific notation is 1.156 times 10^9 estimated.

Identify if it's an independent or dependent event and write the probability as a fraction * What is the probability that from a normal 52 card deck, you randomly draw a 3, and then without replacing the 3, you draw the Queen of Hearts?

Answers

Answer: 0.151 percent

Step-by-step explanation:

The probability of any particular outcome is

(number of possible successful outcomes) / (number of total possibilities)

-- On the first draw, there are 52 possible total outcomes, and

only 4 that are successful ... drawing a 3 .

The probability of drawing a 3 from a full deck is ( 4 / 52 ).

-- On the second draw, there are 51 possible total outcomes (the first

card you drew stayed out), and only one is successful ... drawing the

queen of hearts.

The probability of this particular outcome is ( 1 / 51 ).

-- The probability of both of them is

( 4 / 52 ) x ( 1 / 51 ) =

( 4 / 2,652 ) = about 0.151 percent.

Given that

Fatimah wants to estimate the proportion of students at her school who ate breakfast every day last week.

She takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.

We have to determine

Based on this sample, which of the following is a 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week?

According to the question

She takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.

[tex]\rm P = \dfrac{Sample \ space}{Total \ SRS}\\ \\ P = \dfrac{20}{80}\\ \\ P = \dfrac{1}{4}\\ \\ P = 0.25[/tex]

Therefore,

The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is

=[tex] = 1.96 \times \sqrt{\dfrac{0.25(1-0.25)}{80}}\\ \\ = 1.96 \times \sqrt{\dfrac{0.25\times 0.75}{80}}\\\\ = 1.96 \times 0.40\\\\ = 0.080[/tex]

Hence, The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is 0.25 +0.080.
