A bag contains 2 snickers bars, 8 twix bars, and 5 crunch bars. A candy bar is chosen, the replaced, then another is chosen. What is the probability of choosing a twix bar and then a crunch bar? (Please answer with a fraction and not a percentage)
2 + 8 + 5 = 15 total candy bars.
8 twix, so picking a twix would be 8/15
5 crunch bars, picking a crunch would be 5/15, which reduces to 1/3
Probability of both: 8/15 x 1/3 = 8/45

The isosceles triangle below is rotated along the blue dashed line going through the center. Find the volume of the cone formed by doing this rotation. Round your answer to the nearest tenth.
Answer:
47.1
Step-by-step explanation:
Sorry if its wrong
The cone's volume is approximately 47.1 cubic centimeters, obtained by rotating the provided isosceles triangle along its central blue axis.
The volume of a cone is calculated by the following formula:
[tex]$V = \frac{1}{3}\pi r^2 h$[/tex]
where r is the radius of the base and h is the height of the cone.
In this case, the height is simply the height of the triangle, which is 5 cm.
The radius is a bit trickier.
Notice that the blue dashed line bisects the base of the triangle. Therefore, the radius is half the length of the base, which is 6 cm / 2 = 3 cm.
Substituting these values into the formula, we get:
[tex]$V = \frac{1}{3}\pi (3\text{ cm})^2 (5\text{ cm})$[/tex]
[tex]$V = 15\pi \text{ cm}^3$[/tex]
Rounding this to the nearest tenth, we get:
[tex]$V = 47.1 \text{ cm}^3$[/tex]
Therefore, the volume of the cone is approximately 47.1 cubic centimeters.

What are the wavelengths for X-rays with frequency 3 × 1018? 1 × 10–10 m 3 × 10–10 m 3 × 1026 m 9 × 1026 m
Answer:
[tex]Wavelength=\lambda=1\times 10^{-10}[/tex] mStep-by-step explanation:
Given that the wavelengths for X-rays with frequency [tex]3\times 10^{18}[/tex]
To find the wavelengths for the given X-rays:The distance between two peaks in a wave is called the wavelength.
The value of wavelength is equal to the wave velocity divided by the frequency.
That is written by
[tex]Wavelength=\lambda =\frac{v}{f}[/tex]
[tex]Wavelength =\frac{3\times 10^8}{3\times 10^{18}}[/tex]
[tex]=\frac{10^8}{10^{18}}[/tex]
[tex]=\frac{1}{10^{18}.10^{-8}}[/tex] (by using the property [tex]a^m=\frac{1}{a^{-m}}[/tex])
[tex]=\frac{1}{10^{18-8}}[/tex] (by using the property [tex]a^m.a^n=a^{m+n}[/tex])

Manipulate the triangle so angle B measures
approximately 51°
Notice the straight line p.
What must the measurement of angle C be for p to
remain a straight line?
Angle C should measure approximately
Answer:
37 Degrees
Step-by-step explanation:
Manipulate the triangle so angle A measures approximately 92°.
Manipulate the triangle so angle B measures approximately 51°.
Notice the straight line p.
What must the measurement of angle C be for p to remain a straight line?
Angle C should measure approximately 37 Degrees
There is angle C should measure approximately 37° for line p to remain a straight line.
What are the vertical angles?When two lines intersect at a location, vertical angles are generated. They are always equal to each other.
As we know that a straight line, the sum of the angles is equal to 180°.
So, when angle A measures approximately 92° and angle B measures approximately 51°,
Then, the measurement of angle C must be 180° - 92° - 51° = 37° in order to keep line p a straight line.
Thus, angle C should measure approximately 37° for line p to remain a straight line.

Consider the functions:
f(x) = x2
g(x) = (x + 1)2 – 2
h(x) = (x + 3)2 + 4
Which statement describes the relationship between the minimums of the functions?
a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x).
b The minimum of g(x) is in the fourth quadrant. The minimum of h(x) is in the first quadrant.
c The minimum of g(x) is farther right and down than the minimum of f(x) and h(x).
d The minimum of g(x) is in the second quadrant. The minimum of h(x) is in the first quadrant.
Answer:
a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x)
Step-by-step explanation:
To know the relation between the minima of the functions you calculate the minima by using the derivative:
[tex]f'(x)=2x\\\\g'(x)=2(x+1)\\\\h'(x)=2(x+3)[/tex]
to find the values of x you equal the derivative of the function to zero:
[tex]f'(x)=0;\ x=0;\\\\g'(x)=0; \ x=-1;\\\\h'(x)=0;\ x=-3;[/tex]
by evaluating this values of x you obtain the coordinates of the minima:
[tex]f(0)=0\\\\g(-1)=-2\\\\h(-3)=4[/tex]
hence, the coordinates will be:
f -> (0,0)
g -> (-1,-2)
h -> (-3,4)
hence, the relation is:
a The minimum of h(x) is farther left and up than the minimum of f(x) and g(x).

Answer:
a. 0.4333
b. 255
Step-by-step explanation:
The maximum Error E is 1.3
approximately normal test scores,
Standard Deviation, SD is 6.5
a).
Level of confidence = 99.7%
critical value of z for a two tailed test and 0.3% level of significance is 3
since the sample mean is within 0.5 of the true population mean
hence, the standard dev of mean is given by
[tex]Z_{\alpha}[\frac{\sigma}{\sqrt{n}} ]=E[/tex]
where E = 1.3
[tex]Z_{\alpha}=[/tex] 1.3
[tex]\frac{\sigma}{\sqrt{n}} =\frac{E}{Z_{\alpha}} \\\\\frac{\sigma}{\sqrt{n}} =\frac{1.3}{3}[/tex]
hence the Std of the mean is 0.4333 (to 4 d.p.)
b).
The sample size is computed as follows
making n the subject of formular of the above equation
[tex]\sqrt{n} =\frac{3\sigma}{1.3}} \\\\\sqrt{n} =\frac{3\times 6.5}{1.3}} \\\\n=(\frac{3\times 6.5}{1.3}})^2[/tex]
hence,

In triangle PQR, what is the triangle Q? Please answer as fast as possible! 100 POINTS!!!
Answer:
105 degrees
Step-by-step explanation:
The sum of the angles in a triangle add up to 180. Although we don't the know the numerical values of the angles, we can create an equation with the given expressions:
<P + <Q + <R = 180
(6x + 5) + (11x - 5) + x = 180
18x = 180
x = 10
Now, plug this value of x into the expression for Q:
<Q = 11x - 5 = 11 * 10 - 5 = 110 - 5 = 105
Thus, the measure of angle Q is 105 degrees.
Hope this helps!
Answer:
105 degrees
Step-by-step explanation:
The angles in a triangle must add to 180 degrees
<Q +<P + <R =180
We know <Q is 11x-5, <P is 6x+5 and <R is x, so we can substitute them in
11x-5+6x+5+x=180
Combine like terms
11x+6x+x +5 -5 =180
18x=180
Divide both sides by 18
x=10
Now we know x, and we can substitute that in to to find <Q
<Q=11x-5
<Q=11(10)-5
<Q=110-5
<Q=105
