Ajar contains 3 blue marbles and 2 red marbles. A marble is randomly selected from the jar and replaced, and then a second marble is chosen. The probability that a blue marble was chosen both times is %.
Answers
Answer:
40% probability
Step-by-step explanation:
First, you need to look at the sample space or number of outcomes:
B B B R RThe sample space, or number of outcomes, is 5
If you randomly select one marble and then select another marble after replacing it, you are taking out 2/5 of the marbles in the jar.
B B B R R1/5 2/5 3/5 4/5 5/5
2/5 can be converted into a percentage by turning it into a decimal:
2/5 = .4.4 can be converted into a percentage
.4 = 40%This leaves you with the probability being 40%
Answer: it’s 30%

Explain why 2/3 x 12 can be written as 2 x 12 divided by 3.
Answers
Answer and Step-by-step explanation:
[tex]\frac{2}{3}[/tex] × 12 can also be written as [tex]\frac{2 * 12 }{3}[/tex] because the 12 is multiplying the numerator of the fraction.
12 can also be written as [tex]\frac{12}{1}[/tex].
When we solve, this is what is happening:
[tex]\frac{2}{3}[/tex] × [tex]\frac{12}{1}[/tex]
The 12 will be multiplying the 2, while the 1 will be multiplying the 3. Because 3 times 1 is 3, we don't show the 1. So, that can leave us with 2 being multiplied by 12 in the numerator.

Answers
Answer:
C. The treatment in the experiment must be applied to each of the individuals in the experimental group.
Step-by-step explanation:
Experimental studies are the studies in which the researcher introduced the intervention and the impact of the study. It usually randomized.
Moreover, it must be applied for each and every individual in the experimental group as the variables & conditions would be vary and the same would be applied so that the actual results may be concluded

In an effort to classify a recent tornado, 20 wind speed measurements were randomly selected from within the path of the tornado. Suppose the mean wind speed for this tornado really is greater than 261 mph. Based on the data, if we fined little to no evidence against the null hypothesis that the mean wind speed is 261 mph, we have made _______________. Group of answer choices
Answers
Answer:
Type 2 error
Step-by-step explanation:
H0 : μ = 261
H0 : μ > 261
By failing to reject H0 ; when the it is false. This means accepting null hypothesis when it is actually FALSE. Then a type 2 error has been committed.
This is different from a type 1 error whereby the null hypothesis is rejected when it is actually TRUE.
Hence, by finding no evidence to reject the null hypothesis during statistical testing when the actual windspeed of an F5 tornado during statistical testing is actually greater than 261 mph.

Inez carved a wooden cone from a
cylindrical piece of wood. The cylindrical
piece of wood had a radius of 3 inches
and a height of 15 inches. The cone had
the same radius as the cylinder but was
2 inches shorter. About what volume of
wood did Inez remove from the cylinder to
make the cone?
Answers
Answer:
123 inches³
Step-by-step explanation:
Hi there!
Objective: Find the volume of the cone
We know that the cylinder had a radius of 3 inches and it had a height of 15 inches.
Because the cone had the same radius of the cylinder, we know that it has a radius of 3 inches. And because it was 2 inches shorter, it has a height of 13 inches (15-2=13).
[tex]V=\frac{1}{3} \pi r^2h[/tex] where r is the radius of the cone and h is its height
Plug in the known information (r=3 and h=13)
[tex]V=\frac{1}{3} \pi (3)^2(13)\\V=\frac{1}{3} \pi (9)(13)\\V=\frac{1}{3} \pi(117)\\V=39\pi\\V=123[/tex]
Therefore, the Inez removed about 123 inches³ of wood from the cylinder to make the cone.

The stadium has fixed expenses of $10,000 per event. Last month it put on three major events and spent $72,000, $47,500, and $65,000 in advertising for them respectively. According to the accountant, these events earned a total of $482,000 in revenue. What was the stadium's profit margin last month?
Answers
Answer:
267,500
Step-by-step explanation:
10,000 × 3 = 30,000
30,000 + 72,000 + 47,500 + 65,000 = 214,500
482,000 - 214,500 =267,500
The stadium's profit margin last month was 267,500 dollars.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that stadium has fixed expenses of $10,000 per event.
Since it put on three major events and spent $72,000, $47the,500, and $65 this event raising for them last month respectively
Thus,
10,000 × 3 = 30,000
Total = 30,000 + 72,000 + 47,500 + 65,000 = 214,500
According to the accountant, total amount these event earned ;
$482,000 in revenue.
So,
482,000 - 214,500 =267,500
Hence, the stadium's profit margin last month was 267,500 dollars.

Find the slopes of the lines containing the following. (If an answer is undefined, enter UNDEFINED.)
a)
b)
c)
d)
e)
f)
Answers
Answer:
Step-by-step explanation:
a)
m = y2-y1 / x2-x1
P1 = (3,-4) as (x1,y1)
P2= (5,6) as (x2,y2)
m = 6-(-4) / 5 - 3)
m = 6+4 / 2
m = 10 / 2
m = 5
b)
m = y2-y1 / x2-x1
P1 = (5,-3) as (x1,y1)
P2= (5,6) as (x2,y2)
m= 6-(-3) / 5-5
m = 6+3 / 0 ( the world blows up when you divide by zero :0 undefined )
c)
m = y2-y1 / x2-x1
P1 = (1,-1) as (x1,y1)
P2= (8,-8) as (x2,y2)
m = -8-(-1) / 8-1
m = -8+1 / 7
m = -7 / 7
m = -1
d)
m = y2-y1 / x2-x1
P1 = (-2.8,2) as (x1,y1)
P2= (-1.2,2) as (x2,y2)
m = 2-2 / a number 0 because the numerator is 0 and there is a number in the denominator
e)
m = y2-y1 / x2-x1
P1 = (c,d) as (x1,y1)
P2= (e,f) as (x2,y2)
m = f-d / e-c that's all you can do until we're given those variables
f)
m = y2-y1 / x2-x1
P1 = (0,c) as (x1,y1)
P2= (d,0) as (x2,y2)
m = 0-c / d-0
m = -c /d
Find the volume of the composite solid shown in figure
Answers
Answer:
113.14cm^3
36π cm^3
Step-by-step explanation:
the composite solid is made up of a cylinder and a hemisphere
volume of solid = volume of cylinder + volume of hemisphere
volume of a cylinder = nr^2h
n = 22/7
(22/7) x (3^2) x 2 = 56.57 cm^3
or in terms of pi = 18π
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 22/7
r = radius
(2/3) x (22/7) x (3^3) = 56.57 cm^3
or in terms of pi = 18π
volume of solid = 56.57 cm^3 x 2 = 113.14cm^3
or 18π x 2 = 36π cm^3

The pitch P of a musical tone varies inversely as its wavelength w. One tone has
a pitch of 321 vibrations per second and a wavelength of 10.5 feet. If another
tone has a pitch of 374 vibrations per second, what is its wavelength?
Answers
Answer:
The wavelength of the second pitch is 12.23 feet.
Step-by-step explanation:
Since the pitch P of a musical tone varies inversely as its wavelength w, and one tone has a pitch of 321 vibrations per second and a wavelength of 10.5 feet, if another tone has a pitch of 374 vibrations per second, to determine what is its wavelength the following calculation must be performed:
321 = 10.5
374 = X
374 x 10.5 / 321 = X
3927/321 = X
12.23 = X
Therefore, the wavelength of the second pitch is 12.23 feet.

A private jet flies the same distance in 14 hours that a commercial jet flies in 7 hours. If the speed of the commercial jet was 181mph less than 3 times the speed of the private jet, find the speed of each jet.
Answers
Answer:
Private Jet = 181 mph Commercial Jet = 362 mph
Step-by-step explanation:
private jet travels distance D in 14 hours
commercial jet travels distance D in 7 hours
so commercial jet speed is twice the private jet
y = 2x
commercial jet speed = 3 · (private jet speed) - 181 mph
y = 3x - 181
2x = 3x - 181
2x - 3x = -181
-x = -181
x = 181
y = 2x
y = 362
362 = 3(181) - 181
