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?
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.
There are 1,000 meters in 1 kilometer. How many kilometers are in 3,600 meters?
HELP
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
3.6 km

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?
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
How do I simplify this
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.
I hope this helps you!

The following data shows the quarterly profit (in thousands of dollars) made by a particular company in the past 3 years.
Year Quarter Profit ($1000s)

Required:
a. Construct a time series plot. What type of pattern exists in the data?
b. Develop a three-period moving average for this time series. Compute MSE and a forecast of profit (in $1000s) for the next quarter.
Answer:
208.82 ; 61.33
Step-by-step explanation:
Given the data:
Year Quarter Profit ($1000s)

The 3 period moving average :
Yr Qtr Profit ($1000s)Pt ____ Ft ____ e=(PT-Ft)²
1 _ 1 ___45 __
1 _ 2 __ 51 __
1 _ 3 __ 72 __

3 _ 3__ 70 ______________51.33__ 348.57
3 _ 4 __56 ______________56.67__0.45
MSE = Σ(Pt - Ft)² ÷ n
MSE = (36+75.17+144+961+13.47+300.33+0.11+348.57+0.75) ÷ 9
= 208.82
Forecast for next quarter :
(58 + 70 + 56) / 3 = 184 /3 = 61.33
I put a screenshot, you do the math
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.

9514 1404 393
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.

If L(2, 7) is an endpoint of a line segment, and M(8, 3) is the midpoint, find the other endpoint of the segment.
Answer:
Step-by-step explanation:
From L to M,
change in x-coordinates = 8-2 = 6
change in y-coordinates = 3-7 = -4
Extrapolate from M(8,3) to find the other end of the segment:
8 + 6 = 14
3 - 4 = -1
Endpoint of segment: (14,-1)

after one side of a square was enlarged by 3 inches and the other side was enlarged by 3 inches, the area of the shape was doubled. what was the side of the square.
Answer:
The side of original square was 7.24 inches
Step-by-step explanation:
(x+3)(x+3) =2(x)(x)
x² + 6x + 9 = 2x²
reduce:
x² - 6x - 9 = 0
(x + 1.24)(x - 7.24) = 0
x = 7.24
