What is probability?Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
For, game A:
Odd x odd= odd,odd x even= eveneven x even = evenNot fair
For game B,
Odd + odd = eveneven + even= evenodd+ even= oddAgain, unfair.

Find the m∠r and m∠y
r = 88.5
y = 3/4
Step-by-step explanation:
From the lower triangle,
97 - 2x = 4x -2
Collecting all similar terms, we get
6x = 99 or x = 16.5
From the upper triangle, we can see that
5x + 6 = r ---> 5(16.5) + 6 = r or r = 88.5
Since the sum of all the interior angles of a triangle is equal to 180, we can write
4y + (5x + 6) + r = 180 ---> 4y + 5(16.5) + 6 + 88.5 = 180
4y = 3 or y = 3/4
A Sale at Tinley’s Department Store Tinley’s department store is having a 25% off sale. Victor has a $15 Tinley’s gift certificate that he wants to use towards a sweater with an original price of $32.00. He is unsure which method the sales clerk will use to calculate the amount owed. Method #1: Subtract $15 from the price and take 25% off the resulting price. Method #2: Take 25% off the original price and then subtract $15.
Answer:
Method 1: $12.75
Method 2: $9
Step-by-step explanation:
method #1: 32-15 is $17
In order to take off a percentage, we must find that percentage of the amount. To do this, we must multiply by the percent in decimal form, so
[tex]17 \times .25 = 4.25[/tex]
Now, this amount just represents the percent of 17 we would take off, so we must take that amount off.
[tex]17 - 4.25 = 12.75[/tex]
We would pay $12.75
Method #2:
There are a few ways to do this with 25%. we know 25% is 1/4, and 1/4 or $32 is 8. so we can simply take that off from the start. Otherwise, we can follow the method above as follows
[tex]32 \times .25 = 8[/tex]
Again, this is the amount off so we must subtract.
[tex]32 - 8 = 24[/tex]
now, we subtract 15.
[tex]24 - 15 = 9[/tex]
We would pay $9 using this method.

Mars has an angular size of approximately 8. 0 arcseconds as is 175,000,000 km away. Use S = r x a to figure out the diameter of Mars
The diameter of Mars is 6825 kilometers.
First we quantify angular size a = 8. 0 arcseconds in radians.
a = ( 8/ 3600) × (π/180)
a = 0.000039 radians
also, the distance from Earth to Mars in kilometres is 175,000,000 km
So, r = 175,000,000 km
We use the formula S = r x a to find the diameter of Mars
Substitute r = 175,000,000 and a = 0.000039 in above formula
S = 175,000,000 × 0.000039
S = 6825 km
Therefore, the diameter is 6825 km

write the equation of the cirlce, in standard form which has endpoints of a diameter at (-5,-5) and (7,2)
The equation of the circle in standard form is ( x-h )2 + ( y-k)2 = r2. we can get the equation by putting the values of x coordinates and y coordinates of the circle.
A circle can be defined as a 2-D closed geometrical shape whose boundary points are at an equal distance from the center of the geometry.
Equation of the circle in standard form is,
( x-h )2 + ( y-k)2 = r2
we have to find the the x-coordinate (h) & y-coordinate (k) of the center of the circle by taking the summation of x-coordinates & y-coordinates of the endpoints of the diameter respectively and dividing by 2.
here, h = ( x1 + x2 ) / 2
k = ( y1 + y2 ) / 2
here endpoints of a diameter are at (-5,-5) and (7,2). Calculate the distance between (-5,-5) and (7,2) using the distance formula and divide by 2 to get the circle's radius. Substitute the center coordinates and radius into a standard form to get the equation of the circle.
so, h = -5 + 7 / 2 = 1
k = -5 + 2 / 2 = -3/2
Putting all the values we get the equation of circle in standard form.

For the 1996 General Social Survey, conducted by the National Opinion Research Center NORC, 842 replied "yes" and 982 replied "no. " Let π denote the population proportion who would reply "yes. " Find the P-value for testing H0 : π = 0. 5 using the score test, and construct a 95% confidence interval for π. Interpret the results
At a significance level of 0.05, the sample data is not consistent with the null hypothesis that the proportion of population who would respond "yes" is 0.5. The P-value of 0.0005 is less than 0.05, and also the sample proportion 0.4616 is not in the interval (0.477, 0.523) which we found as 95% Confidence interval.
Therefore, we reject the null hypothesis and conclude that the population proportion of "yes" responses is different from 0.5.
The P-value for a score test for H0: π = 0.5 can be found using the z-score and a standard normal table. The z-score is calculated as
[tex]z = \frac{x-0.5}{0.5\sqrt{\frac{x-0.5}{n} } }[/tex], that is
z = (x - 0.5) / (√(0.5(1 - 0.5) / n)
where x is the sample proportion of "yes" responses (842 / (842 + 982) = 0.4616), π is the population proportion of "yes" responses, and n is the sample size (842 + 982 = 1824).
[tex]z = \frac{0.4616-0.5}{0.5\sqrt{\frac{0.4616-0.5}{1824} } }[/tex]
= (0.4616 - 0.5)/ (√(0.5(1 - 0.5) / 1824)
This gives a z-score of -3.28.
To find the P-value, we can use the standard normal table to find the probability of observing a z-score less than -3.28. This P-value is approximately 0.0005, which is less than the commonly used significance level of 0.05. Therefore, we would reject the null hypothesis that π = 0.5.
To construct a 95% confidence interval for π, we can use the formula for a normal approximation interval:
π ± z×(√(π(1-π) / n)) that is
[tex]\pi \frac{+}{} z\frac{\pi (1 -\pi )}{n}[/tex]
Where π = 0.5, z = 1.96 (for a 95% confidence level), and n = 1824.
This gives a 95% confidence interval of (0.477, 0.523)

On solving the provided proportionality question we got that, U = 7.72, is rounded off nearest to tenth digit.
What is proportionality?When two quantities or variables are linearly related in mathematics, the term "proportional" is used. Both quantities increase by two times when one increases by two. Each variable decreases in proportion to the other when it falls to 1/100th of its previous value.We must determine the ratio of the two quantities for each value supplied in order to determine if two quantities are proportionate. The proportionate link between them is evident if their proportions are equal. Their connection is not proportionate if all the ratios are out of balance.

U/5 = 17/11
U = 17/11 X 5

5. Write two expressions for the area of the big rectangle.
Answer:
Two expressions for the area are;
i) x/3 + 2·y + 6
ii) (1/3) × (x + 6·y + 18)
Step-by-step explanation:
The given dimension of the rectangle are;
The height of the rectangle, h = 1/3
The width of the smallest rectangle, w₁ = x
The width of the med sized rectangle, w₂ = 6·y
The width the large rectangle, w₃ = 18
The area, 'A', of the entire rectangular figure, the big rectangle, can be expressed as follows;
A = A₁ + A₂ + A₃
Where;
A₁ = The area of the smallest rectangle
A₂ = The area of the mid sized rectangle
A₃ = The area of the large rectangle
∴ A = (1/3) × x + (1/3) × 6·y + (1/3) × 18 = x/3 + 2·y + 6
The area of the big rectangle. 'A', can also be found as follows;
A = (1/3) × (x + 6·y + 18)
Therefore, two expressions for the area of the big rectangle are;
x/3 + 2·y + 6 and (1/3) × (x + 6·y + 18).

What is an equation ?
In mathematics, an equation is a statement that asserts the equality of two expressions, typically containing one or more variables. Equations are often written in the form of "expression = expression" or "expression - expression = 0"
Let's call the number of bhajis in the second bag "x".
We know that he total number of bhajis after emptying both bags onto the plate is 50.
So we can write an equation:
42 + x = 50
To solve for x, we can subtract 42 from both sides:
x = 50 - 42
x = 8
Therefore, there were 8 bhajis in the second bag.
