Answer:
The probability of pulling two of the same types of cookies in a row without replacement is [tex]\frac{51}{105}[/tex].
Step-by-step explanation:
There are a total of 21 * 20 = 420 different outcomes (After you take one cookie out, you aren't replacing it, so there will be 20 cookies in the jar on the second grab). There are a total of 9 * 8 = 72 different combinations of two sugar cookies, and 12 * 11 = 132 different combinations of two snickerdoodle cookies, so the total probability of pulling two of the same types of cookies in a row without replacement is [tex]\frac{132+72}{420} = \frac{204}{420} = \frac{51}{105}[/tex].

Step-by-step explanation:
Two airplanes leave an airport at the same time, the first headed due north and the second at a bearing of N42^ E . At 2:00PM, the first airplane is 312 miles from the airport while the second airplane is 487 miles from the airport. Assuming both followed linear paths from the airport, how far apart are the two airplanes at 2:00PM?
Answer:
The two airplanes are about 330miles apart.
Step-by-step explanation:
The diagram interpreting the question has been attached to this response.
As shown in the diagram,
i. the airplanes leave at point C.
ii. at 2.00pm the first and second airplanes are at points A and B respectively, where they are 312miles and 487miles away from the starting point C in directions due north and N42E from the point C.
iii. the points A, B and C form a triangle with sides a, b and c.
To solve for the value of c which is the distance between the two planes at 2.00pm, the cosine rule is used.
c² = a² + b² - 2abcosC --------------(i)
where;
b = 312miles
a = 487miles
C = 42°
Substitute these values into equation (i) and solve as follows;
c² = (487)² + (312)² - 2(312)(487)cos(42)
c² = (237169) + (97344) - 303888cos(42)
c² = (237169) + (97344) - 303888(0.7431)
c² = 334513 - 225819.1728
c² = 108693.8272
Take the square root of both sides
√c² = √108693.8272
c = 329.69
c ≅ 330miles
Therefore, the two airplanes are far apart by 330miles

Determine the null hypothesis and the alternate hypothesis: ************************** The August 2008 edition of Academy of Management Journal featured an investigation of the performance and timing of corporate acquisitions. The investigation discovered that in a random sample of 2778 firms, 748 announced one or more acquisitions during the year 2000. Does the sample provide sufficient evidence to indicate that the true percentage of all firms that announced one or more acquisitions during the year 2000 is less than 30%
Answer:
Following are answer to these question:
[tex]\LARGE H_0: p = 30 \%\\\\\LARGE H_A: p < 30 \%[/tex]
Step-by-step explanation:
Even though researchers try and check whether the real percentage of all companies announcing one or more purchases that year 2000 is less than 30%, the invariant hypothesis therefore becomes as follows:
[tex]\LARGE H_0: p = 30 \%\\\\\LARGE H_A: p < 30 \%[/tex]
It is desired to convert from slow sand filters to high-rate filters. The slow sand filters operate at a rate of 10 million gallons/acre-day and have a total area of 15 acres. Assuming the high-rate filters are rated for 6 gpm/ft2, and each filter has an area of 1,000 ft2, how many filters are required
Answer:
Total 17 high rate filters are required
Step-by-step explanation:
Given -
Rate of filtration of slow sand filters = 10 million gallons/acre-day
Total million gallons of water filtered per day = 10 million gallons/acre-day * 15 acres
= 150 Million gallons per day
Rate of filtration of high rate filters = 6 gpm/ft2
Area of one high rate filter = 1,000 ft2
Volume of water filtered by 1 high rate filter is 6 gpm/ft2 *1,000 ft2 = 6000 gallons per minute = 8640000 gallon per day
Number of filters required = 150 million gallons per day /8640000 gallon per day
150 * 10^6/8640000
17
Total 17 high rate filters are required

Answer:
7
Step-by-step explanation:
Given :
A right angled triangle with one angle 64° and side 15 .And we need to find the value of x to the nearest tenth. So the correct approach will be ,
[tex]:\implies[/tex] tan 64° = p/b
[tex]:\implies[/tex] tan 64° = 15/x
[tex]:\implies[/tex] x = 15 / tan64°
[tex]:\implies[/tex] x ≈ 7
He commited a mistake in 2nd step. He should have written 15/ tan64° .Hence the correct answer is 7 .
What is the value of In e^4?
Answer:
4
Step-by-step explanation:
The easiest way to solve this is just to put it in your calculator.
But if you want to go deeper, then ln(x)^4 = 4*ln(x)
Since x in this case = e then ln (e)^1 = 1.
ln(e)^4 = 4*ln(e) = 4
A sixth grade class recorded the number of letters in each students first name. The results are shown in the dot plot. Which is the best representation of the center of this data set?
Answer:
the center of the data set is 7 so probably 7
7 is the best representation of the center of given data set.
The correct answer is an option (C).
What is center of data?"It is the middle of a distribution.""Mostly, The measures of the center of the data are the mean and the median."What is mean?"It is the average of the given numbers."
What is median?"I is the middle value of a sorted list of numbers."
For given question,
We have been given a dot plot of the number of letters in each students first name.
From the given dot plot,
We have data as 3, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6,6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10, 10, 11, 11, 11
From above data,
the total number of students in the class are n = 30
We write 3, 4, 4, 5, 5, 5, 5, 6, 6, 6, 6, 6, 6,6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10, 10, 11, 11, 11 as 3, (4 × 2), (5 × 4), (6 × 7), (7 × 7), (8 × 3), 9, (10 × 2), (11 × 3)
So, the mean of the above data would be,
[tex]\Rightarrow \bar{X}=\frac{3+ (4\times 2)+(5\times 4)+(6\times 7)+(7\times 7)+(8\times 3)+9+(10\times 2)+(11\times 3)}{30}\\\\\Rightarrow \bar{X}=\frac{208}{30}\\\\\Rightarrow \bar{X}=6.93\\\\\Rightarrow \bar{X}\approx 7[/tex]
From above data we can observe that there are two numbers in middle of the data 6 and 7.
So, the median would be,
[tex]\Rightarrow M=\frac{6+7}{2}\\\\\Rightarrow M=6.5\\\\\Rightarrow M\approx 7[/tex]
Therefore, 7 is the best representation of the center of given data set.
The correct answer is an option (C).

The point C (-3,-1) is rotated 180 clockwise around the origin.
What are the coordinates of the resulting point, C'?
Answer: [tex](3,1)[/tex]
Step-by-step explanation:
Given
The point C [tex](-3,-1)[/tex] is rotated [tex]180^{\circ}[/tex] clockwise about the origin
If a point is rotated [tex]180^{\circ}[/tex] about the origin, then the sign of the co-ordinates changes without changing the order of coordinates.
So,C [tex](-3,-1)[/tex] becomes C' [tex](3,1)[/tex] after the rotation.

A paint can has a radius of 4 inches and a height of 15 inches. What is the volume of the paint can? Round to t tenth. Use 3.14 for cubic inches
Answer:
Step-by-step explanation:
r=4 in
h=15 in
The paint can is a cylinder. The volume of the cylinder is: V=S×h (S stands for the area of the base, h is for height).
The area of our cylinder's base is a circle, so:
S=πr²=4²×π=16π≈50.24 (in²)
Thus, the volume is:
V≈50.24×15≈753.6 (in³)
