An experiment consists on rolling a fair number cube. There are 6 possible outcomes: 1, 2, 3, 4, 5, and 6. Find the probability P(rolling a 7).
Answers
Answer:
0
Step-by-step explanation:
The only possible outcomes on the die are 1,2,3,4,5,6.
Since 7 is not in the possible outcome list, It is impossible to obtain a 7 on this 6-sided die.
If the question had asked for the probability of other values, it would have been 1/6, because you can get each number at least once every 6 rolls. This, however varies in terms of experimental probability

A company sells two versions of an antivirus software. The home edition costs $23.50, and the business edition costs $58.75. Last week, the company earned $29,668.75 from selling 745 copies of the software.
If x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold, which system of equations represents this situation?
Answers
Answer:
x + y = 745
23.50x + 58.75y = 29,668.75
Step-by-step explanation:
Since 745 copies were sold and x represents the number of copies of the home edition sold and y represents the number of copies of the business edition sold:
x + y = 745
Since the home edition costs $23.50, and the business edition costs $58.75:
The money earned from home edition is = 23.50x
The money earned from business edition is = 58.75y
Since the company earned $29,668.75:
23.50x + 58.75y = 29,668.75
Find the value of x. The polygons are similar, but not necessarily drawn to scale Answer choice: A) 162 B) 81 C) 9 D) 4 Please help, will mark brainliest!
Answers
Answer:
9 is the answer.
Step-by-step explanation:
The scale they are using is 2/3, meaning that 18 is two thirds of 27.
And following that rule that would mean the 6 is two thirds of x.
So if you just divide 6 in half you'll get 3 which would be 1/3, since 6 was 2/3's, and if you add the new found 1/3 to the already 2/3's or if you add 6 and 3 together you get 9. And that makes them similar polygons or that makes ABCD a scale 2/3's scale of JKLM.
Option C is correct. The value of x is 9.
What is similar polygon?
Two polygons with the same shape are called similar polygons.
What is scale factor of two polygons?If two polygons are similar then the ratio of lengths of any two corresponding sides is called the scale factor.
According to the given question
Polygons ABDC is similar to Polygon KJML.
Since, these polygons are similar to each other therefore, the ratio of lengths of corresponding sides will be equal.
⇒ [tex]\frac{AB}{DC} =\frac{JM}{ML}[/tex]
⇒[tex]\frac{18}{6} = \frac{27}{x}[/tex]
⇒ [tex]3 = \frac{27}{x}[/tex]
⇒ [tex]x = 9[/tex]
Therefore, the value of x is 9.
Hence, option C is correct.

c2*sin(wt)+c1*cos(wt)= A*Sin(wt+phi), where c2=Acos(Phi) and c1=Asin(Phi). They ask me to find the amplitude of the function 2 sin(4pi*t)+5 cos(4pi*t), in terms of A sin(wt+phi). How do i do this?
Answers
The amplitude of [tex]A\sin(\omega t+\phi)[/tex] is the absolute value of [tex]A[/tex]. So first you need to condense the given function into one sine expression.
Recall that
[tex]A\sin(\omega t+\phi)=A\sin(\omega t)\cos\phi+A\cos(\omega t)\sin\phi[/tex]
so you need to choose [tex]\phi[/tex] and [tex]\omega[/tex] accordingly.
If we line up the terms of the given function with the expanded one above, we should have
[tex]2\sin(4\pi t)+5\cos(4\pi t)\implies\begin{cases}A\cos\phi=2\\A\sin\phi=5\\\omega=4\pi\end{cases}[/tex]
Now, using the Pythagorean identity,
[tex](A\sin\phi)^2+(A\cos\phi)^2=2^2+5^2\implies A^2=29\implies A=\pm\sqrt{29}[/tex]
so the amplitude is √29.
Just for completeness, we also get
[tex]\tan\phi=\dfrac{\sin\phi}{\cos\phi}=\dfrac52\implies\phi=\tan^{-1}\left(\dfrac52\right)+n\pi[/tex]
where [tex]n[/tex] is any integer.

What is the total surface area of the figure shown?
Answers
Answer:
Surface area of the figure = 1000 in²
Step-by-step explanation:
From the figure attached,
Two rectangular prisms A and B have been shown with the dimensions.
Surface area of a rectangular prism = 2(length + width) × height
Surface area of prism A = 2(9 + 10) × 20
= 760 in²
Surface area of prism B = 2(15 + 10) × 8
= 16×25
= 400 in²
But one surface of prism B along the width and the same area of prism A are hidden.
Area of the hidden surfaces = 2(10 × 8)
= 160 in²
Total surface area of the figure = 760 + 400 - 160
= 1000 in²

Find m∠1. 40° 50° 65° 70°
Answers
Answer:
50 degrees
Step-by-step explanation:
First, look at the exterior angle with the measure of 140 degrees. The corresponding interior angle has a measure of 40 degrees. Add together 90 and 40 and subtract that sum from 180
180 - (90 + 40) Add in the parentheses
180 - 130 Subtract
50 degrees
explanation: at the bottom of the triangle you get a supplementary angle which when you add both angles up they equal 180 degrees and one of the angles are 140. se you subtract 140 from 180 and you get 40 degrees. they also give you the value of an angle inside of the triangle which is 90 degrees because of the square in the bottom left. now that you have two angles (40 & 90) add them up subtract them from 180 and you get 50.

As we know, sum of an infinite geometric series,
[tex]S=\frac{a}{1-r}[/tex]
Here a = first term of the series
and r = common ratio.
If |r| < 1 Series converges
If |r| ≥ 1 Series diverges
For Option (1),
S = 262 + 301.3 + 346.5.........
Common ratio = [tex]\frac{301.3}{4.2}[/tex] = 1.15
Since |r| = 1.15 > 1
Series will diverge
Option (2),
S = 4.2 + 3.57 + 3.0345..........
Common ratio = [tex]\frac{3.57}{4.2}[/tex] = 0.85
Since |r| < 1
Series will converge.
Option (3),
S = 6651 + 729 + 81........
Common ratio = [tex]\frac{729}{6651}[/tex] = 0.11
Since |r| < 1
Series will converge.
Option (4),
S = 100, 50, 25...........
Common ratio = [tex]\frac{50}{100}=\frac{1}{2}[/tex]
Since |r| < 1
