Answer:
22
Step-by-step explanation:
You can substitute a with 15. So now, the equation is 2(15 - 5) + 2.
We can use PEMDAS to solve this equation now. Since the P is first in PEMDAS, we have to solve what's inside the parentheses first. 15 - 5 would be 10. So now the equation is 2(10) + 2.
There's no more to solve in the parentheses, so we can move on to multiplication. 2(10) would be 20. So now the equation is 20 + 2.
Add 20 + 2 and you get 22. Hope that helps!

Answer: x = -3; y = -8
Step-by-step explanation:
Multiply second equation by -1 and add to first equation. The y term zeros out, leaving you with -3x = 9, so x = -3.
Then go back and sub -3 in for x in either equation, and solve for y. If you use the first equation, you get 4(-3) -3y = 12
-12 -3y = 12
-3y = 24
y = -8

There are 1,000 meters in 1 kilometer. How many kilometers are in 3,600 meters?
HELP
Answers
Answer:
A. 3.6 kilometers
Step-by-step explanation:
1000 meters = 1 km
3600 meters = x km
Set as a ratio:
1000 : 1 = 3600 : x
Then divide:
[tex]\frac{3600}{1000} = \frac{x}{1} = x[/tex]
so 3600/1000 = 3.6 = x

How do I simplify this
Answers
Answer:
96/18
Step-by-step explanation:
To simplify you need to turn it into an improper fraction. This means that the numerator (the number on top) is greater than the denominator (the number on the bottom). The improper fraction form of 5 6/18 is 96/18. I believe this is the answer to your question.

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.

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).
(i) the time each person ran
(ii) the number of calories each person burned
(iii) the age of the runners (iv) the speed at which each person ran
Answers
Answer:
A. observational
B. Time spent running
C. Calories burnt
D. Speed person ran
Step-by-step explanation:
A. This is an observational study as these selected runners are being observed but no experiment is being carried out
B. The explanatory variable or independent variable is the I'm the individuals spend running. This is quantitative.
C. The response variable Is the amount of calories that is being burnt. This is also quantitative.
D. The lurking variable is iv. It is the speed at which each person ran

Answer:
B They are similar, but not congruent.
Step-by-step explanation:
Reflection, rotation, and translation are "rigid" transformations. They result in congruent figures.
Dilation is not a rigid transformation. For any dilation scale factor other than 1, the figures will be different sizes, so will not be congruent. They will be similar. (Angles will be congruent, and lines/sides will be parallel.)
The combination of dilation (by 0.5) and reflection results in similar, but not congruent, figures.

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.
