See below.
Step-by-step explanation:
I've never seen one asked quite this way, but I think I have it figured out.
The objective here is to get the right answer for each square. The answer is either the one next to the 'x', which means you put an 'x' in the tic-tac-toe square or the answer is the one next to the 'O', which means you put an 'O' in the tic-tac-toe square.
I will number them boxes 1-3 on the top row, 4-6 for the next, and 7-9 for the bottom row.
Box 1: In a fraction, you subtract the bottom exponent from the top exponent, so the proper exponent is 10 - 2 = 8. That is an O for g^8.
Box 2: A power raised to a power - multiply the exponents. 2*6=12. That is an X for m^12 for box 2.
Box 3: for multiplying the same base, you add the exponents. 4+5=9. That gives us y^9, which is a X for box 3.
Box 4: j is a factor four times, so that is j^4. That puts an O in Box 4.
Box 5: In a fraction, you subtract the bottom exponent from the top exponent, so we get -2 - (-6) = -2 + 6 = 4. The correct expression is h^4, so we have an X for box 5.
Box 6: A power to a power, you multiply the exponents so the first part becomes m^8. Now we have m^8 * m^5. For multiplying the same base, you add the exponents. 8+5=13. That gives us m^13, which puts an O in box 6.
Box 7: The top is a power to a power so we multiply the exponents. 4*5=20. The top is b^20.
On the bottom, for multiplying the same base, you add the exponents. 2+3=5, so the bottom is b^5.
Now we have a fraction, (b^20)/(b^5). In a fraction, you subtract the bottom exponent from the top exponent, so we have 20 - 5 = 15, and thus b^15. That gives us an X for box 7.
Box 8: A fraction IS a division, so we do divisons and fractions the same way. The p^3 on the left is the top (numerator) and the p^2 part is the bottom (denominator). So 3-2=1. But P^1 is just P, so we have an O for box 8.
Box 9: For the numerator, it is a power to a power so we multiply the exponents and get k^12.
For the denominator, we are multiplying the same base, so you add the exponents. 7 + (-5) = 2, and we get k^2 for the denominator
Now we have the fraction of k^12 OVER k^2. In a fraction, you subtract the bottom exponent from the top exponent. 12-2=10. We get k^10, giving us an X for box 9.
So here is what we get for tic-tac-toe.
0 X X
O X 0
X O X
We get 3 in a row in boxes 3, 5, and 7. The exponents in those problems are 9, 4, and 15 respectively. The product of thse 3 numbers is 540.
This was a LOT of steps, so I encourage you to check every little multiplication and addition I did.
Hope this helps.

Answer:
a) P( [tex]Y^{C}[/tex] | X ) = 0.180
b) P(Y | [tex]X^{C}[/tex] ) = 0.998
Step-by-step explanation:
Let
P(X) - Probability that he acts hungry
P(Y) - Probability that he had ate dinner,
Given,
P(X | Y) = 0.5
P(X | [tex]Y^{C}[/tex] ) = 0.99
P(Y) = 0.9
a.)
P( [tex]Y^{C}[/tex] | X ) = [tex]\frac{P( X | Y^{C} ). P(Y^{C} ) }{P( X | Y^{C} ). P(Y^{C} ) + P( X | Y ) . P (Y) }[/tex]
= [tex]\frac{(0.99)(0.1)}{(0.99)(0.1) + (0.5)(0.9)} = \frac{0.099}{0.549}[/tex] = 0.180
⇒P( [tex]Y^{C}[/tex] | X ) = 0.180
b.)
P(Y | [tex]X^{C}[/tex] ) = [tex]\frac{(1 - P(X | Y ) ) . P(Y)}{P( X^{C} ) } = \frac{(1 - P(X | Y ) ) . P(Y)}{ 1 - P( X ) }[/tex]
= [tex]\frac{(1 - 0.5)(0.9)}{1 - [(0.99)(0.1) + (0.5)(0.9) ]} = \frac{(0.5)(0.9)}{1 - [(0.099) + (0.45) ]} = \frac{0.45}{1 - [0.540]} = \frac{0.45}{0.451}[/tex] = 0.998
⇒P(Y | [tex]X^{C}[/tex] ) = 0.998

Solid A is dilated using a scale factor of 2⁄5, resulting in Solid B. Solid B is also dilated using a scale factor of 2⁄5, resulting in Solid C. If the volume of Solid B is 72 km^3, what is the volume of Solid A and Solid C?
Answers
Answer:
28.8 and 180
Step-by-step explanation:
you just times B by 2/5 to get C and divide it by 2/5 to get A
C = (72)(2/5) = 28.8 km³
A = (72)/(2/5) = 180 km³
We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.

Find the z-score for an ACT score of 26.
Answers
Answer:
The z-score for an ACT score of 26 is 0.17.
Step-by-step explanation:
Z-score:
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In a particular year, the mean score on the ACT test was 25 and the standard deviation was 5.9.
This means that [tex]\mu = 25, \sigma = 5.9[/tex]
Find the z-score for an ACT score of 26.
This is Z when X = 26. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{26 - 25}{5.9}[/tex]
[tex]Z = 0.17[/tex]
The z-score for an ACT score of 26 is 0.17.

PLS HELP ASAP If -2 is added to each of the x and y intercepts of the line 3x + 2y = 6, find the new equation of the line
Answers
Answer:
3x + 2y = -4
Step-by-step explanation:
x intercept of the line occurs at y = 0
Given the equation 3x+2y = 6
3x+2(0) = 6
3x = 6
x = 2
The x intercept is at (2, 0)
Adding -2 to each axis will give (2-2, 0-2) = (0, -2)
y intercept of the line occurs at x = 0
Given the equation 3x+2y = 6
3(0)+2y = 6
2y = 6
y =3
The x intercept is at (0, 3)
Adding -2 to each axis will give (0-2, 3-2) = (-2, 1)
The new coordinates are (0, -2 and (-2, 1)
Using the point slope form of the equation y - y0 = m(x-x0)
slope m = y2-y1/x2-x1
m = 1-(-2)/-2-0
m = 1+2/-2
m = -3/2
Using m = -3/2 and (0, -2)
y - (-2) = -3/2(x-0)
y+2 = -3/2 x
2(y+2) = -3x
2y+4 = -3x
-3x-2y = 4
3x + 2y = -4
Hence the required equation is 3x + 2y = -4
Each edge of a Rubik's cube has a length of 5.7 centimeters. What is the volume of
the Rubik's cube?
Answers
185.193 Cm, 5.7x5.7x5.7 is the volume
The volume of the Rubik's cube is 183.51 cubic centimeters.
To find the volume of a Rubik's cube, we can use the formula V = s ³, where V represents the volume and s represents the length of each edge.
In this case, the length of each edge is given as 5.7 centimeters.
Substituting this value into the formula, we have:
V = (5.7 cm) ³
Calculating the volume:
V = 5.7 cm * 5.7 cm * 5.7 cm
V = 32.49 * 5.7
V = 183.51 cm ³
Therefore, the volume of the Rubik's cube is 183.51 cubic centimeters.

Suppose that A and B are two events in a sample space, S, which are independent and which have equal probability, p, of occurring. Suppose further that the probability that neither A nor B occurs is 0.81. Find the probability that both A and B occur.
Answers
Answer:
The probability that both A and B occur is P = 0.01
Step-by-step explanation:
Both events A and B have a probability p of occurring.
Then both events A and B have a probability (1 - p) of NOT occurring.
The probability that neither A or B occurs is equal to the product of the individual probabilities, and this is equal to 0.81, then:
(1 - p)*(1 - p) = 0.81
1 - 2*p + p^2 = 0.81
p^2 - 2*p + 0.19 = 0
We can solve this if we use Bhaskara's equation, the two solutions are:
[tex]p = \frac{-(-2) +- \sqrt{(-2)^2 - 4*1*0.19} }{2*1} = \frac{2 + - 1.8}{2}[/tex]
Then the two solutions are:
p = (2 + 1.8)/2 = 3.8/2 = 1.9
A probability must be a number between zero and one, and this is larger than one, so this solution can be discarded.
the other solution is:
p = (2 - 1.8)/2 = 0.2/2 = 0.1
This means that the probability that event A occurs is p = 0.1
And the probability that event B occurs is p = 0.1
The probability that both events occur is equal to the product of the individual probabilities, which is:
P = 0.1*0.1 = 0.01

8 + 3x = −13
Answers
Answer:
x=-7
Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
Simplifying
-1(8 + -3x) = 13
(8 * -1 + -3x * -1) = 13
(-8 + 3x) = 13
Solving
-8 + 3x = 13
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '8' to each side of the equation.
-8 + 8 + 3x = 13 + 8
Combine like terms: -8 + 8 = 0
0 + 3x = 13 + 8
3x = 13 + 8
Combine like terms: 13 + 8 = 21
3x = 21
Divide each side by '3'.
x = 7
Simplifying
x = 7

Integrating the above equation with respect to time, we get -
[tex]\int\ \frac{dP}{0.4p-450} = \int\ dt\\[/tex]
let us define new variable x
[tex]x = 0.4p - 450 \\dx = 0.4 dy[/tex]
substituting these values in above integral equation, we get -
[tex]\frac{1}{0.4} \int\ \frac{dx}{x} = \int\ dt\\ln x = 0.4 t + C\\x = ce^{0.4t}[/tex]
[tex]P (t) = \frac{C}{0.4} e^{0.4t} +1125\\[/tex]
at t = 0, P (0) = 1075, using this condition, we get -
[tex]\frac{c}{0.4} = -50\\P(t) = 50 e^{0.4t} +1125 \\t = 7.78\\P(0) = 1125 - \frac{1125}{e^{4.8}} = 1116[/tex]
