Suppose that a point (x, y) is chosen from the unit square S = [0,1]×[0,1] using the uniform probability law — the probability that (x, y) is in a subset A of S is equal to the area of A:
P ((x, y) ∈ A) = area(A) for all A ⊂ S.
(a)What is the probability that x + y <1/3 ?
(b)What is the probability that x + y <3/2 ?
(c)Find an algebraic expression F(u) for
F(u) = P (x + y ≤ u).

The probability of success is 0.2. The result is obtained by adding the probability of getting 9 and the probability of getting 10.

Probability of an event can be expressed as

P(A) = n(A) / n(S)

Where

The probability of A or B can be calculated by

P(A or B) = P(A + P(B)

A 10-sided die is rolled. Each side of the die is labeled with a number from 1 to 10. A number of 9 or 10 should be rolled to make a player succeed. Find the probability of success!

The number of each side of die are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

The probability of success is the probability of getting 9 or 10.

P(9) = 1/10

P(10) = 1/10

P(9 or 10) = P(9) + P(10)

P(9 or 10) = 1/10 + 1/10

P(9 or 10) = 2/10

P(9 or 10) = 1/5

P(9 or 10) = 0.2

Hence, the probability that a player would succeed is 0.2.

The area of the shaded region is 36.53 cm^2 and the perimeter of the shaded region is 8π cm.

What is area and perimeter?

The area of a shape or figure is its area, whereas the perimeter of a shape is its outer boundary over a given distance. Area is measured in square units or unit2 while perimeter is measured in the same unit.

The circumference of a shape is known as its perimeter. The lengths of all four sides must be added in order to determine a rectangle's or square's perimeter.

Radius, r = 8 cm

Perimeter of a circle = 2πr

Perimeter of s quarter circle = 2πr/4 = 1/2πr

Perimeter of Shaded part = 1/2 * 2πr

                                          = 1/2 × 2 × π × 8

                                          = 8πcm.

Area of a circle = 2πr²

Area of quarter circle = 2πr²/4 = 1/2πr²

Area of a square = length ²

Area of Shaded part = Area of Quarter-circle - Area of Square

                                  = 0.5π(8)² - 8²

                                   = 0.5π(64) - 64

Area of Shaded part  = 36.53 cm^2

Hence, the area of the shaded region is 36.53 cm^2 and the perimeter of the shaded region is 8π cm.

Step-by-step explanation:

Let x be the number of bricks Ram laid.

Shyam laid x/2 bricks.

Therefore, x + x/2 + 250 = x(3/2) + 250 = x(3/2) = 300

x = (2*300)/3 = 200

Ram laid 200 bricks.

Shyam laid 200/2 = 100 bricks.

According to the given information the standard error for the sample proportion is 0.024.

When determining if two ratios as well as fractions are equivalent, using proportion formula is utilized. By dividing the supplied numbers, we may determine the missing value. One way to express the percentage formula is as a: Whereas a and d are indeed the extremes values and b and c are indeed the mean terms, a: b::c : d = a/b = c/d 

Sample size (n) = 146 participants

The percentage (p) of respondents who said they would be interested in attending the program again is as follows:

[tex]\begin{aligned}& p=\frac{132}{146} \\& p=0.9041\end{aligned}[/tex]

For a sample of size "n" and percentage "p," the standard error is as follows:

Applying proportions, the amount of money Bob saved is $18.

Proportions can also be used to express a relationship between two or more values in the form of a ratio, such as a:b, where a and b are values being compared.

We can start the problem by using the proportion of saving to earning, which is 9/16.

If for every $16 he earns babysitting, he saves $9, then for $32 that he earned babysitting, he saved:

$9 / (16/32) = $9 * 2 = $18

The radius of the circle will be [tex]\sqrt{22}[/tex].

In our question, we shall first extend QRS to the circle's point T.

According to the power of a point.

[tex]QP^{2}[/tex]  =  QR*QT

[tex]6^{2}[/tex]  =  3*QT

QT = 12

Since QR = 3, RT = 9.

Since RS = 3, ST = 6.

Draw OT and OR, creating a triangle(TSO) and triangle(RSO).

OT and OR are radii, Let the radius be r.

Use the Law of Cosines on these two triangles.

OT2  =  [tex]r^{2}[/tex]  =  [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)

OR2  =  r2  =  [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)

Since these are equal:

[tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)  =  [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)

40 - 24*cos(TSO)  =  13 - 12*cos(RSO)

Since angle(RSO) is supplementary to angle(TSO),  cos(RSO) = - cos(TSO)

40 - 24*cos(TSO)  =  13 + 12*cos(TSO)

27  =  36*cos(TSO)

0.75  =  cos(TSO)

Since  [tex]OT^{2}[/tex]  =  [tex]r^{2}[/tex]  =  [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)

[tex]r^{2}[/tex]  =  40 - 24*0.75  

[tex]r^{2}[/tex]  =  22

r  =  [tex]\sqrt{22}[/tex]

Hence the radius of the given circle will be [tex]\sqrt{22}[/tex].

Answer: C. [tex]2.8[/tex]

Step-by-step explanation:

Using the distance formula, [tex]\sqrt{(-1-1)^2 +(-1-1)^2} \approx 2.8[/tex].

Company A charges $90 for unlimited mileages, while company B charges $75 initial fee and #0.6 per mile driven. Company A will  charge less than company B if the number of miles driven is greater than 25 miles or m > 25.

To solve the problem, we need to translate the word problem into equations.

Let C(A) and C(B) represent the cost charged by company A and B respectively. Let m = the number of mileages.

Company A charges $90 and allows unlimited mileage, it means the charge is a constant and it is not a function of mileage.

Hence,

C(A) = 90

Company B has an initial fee of $75 and charges an additional $0.60 for every mile driven. Hence,

C(B) = 75 + 0.6 m

The inequality that translate: for what mileages will company A charge less than company B is:

C(A) < C(B)

90 < 75 + 0.6 m

To solve the above inequality, subtract 75 from both sides:

90 - 75 < 75 + 0.6 m - 75

15 < 0.6 m

m > 15/0.6

m > 25

Hence, if the mileages > 25 miles, company A charges less than company B.

Answer: To determine if there is evidence to suggest that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than those that were, we can conduct a two-sample proportion test.

The null hypothesis is that the proportion of individuals who caught pertussis and were not up to date on their booster shot is the same as the proportion of individuals who caught pertussis and were up to date on their booster shot.

H0: p1 = p2

The alternative hypothesis is that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than the proportion of individuals who caught pertussis and were up to date on their booster shot.

Ha: p1 > p2

Using a two-sample proportion test with a significance level of 0.05, we can calculate the test statistic and p-value.

p1 = 15/132 = 0.1136

p2 = 11/368 = 0.0301

p = (15 + 11)/(132 + 368) = 0.0564

SE = sqrt{p(1-p)((1/132)+(1/368))} = 0.0165

z = (p1 - p2) / SE = 4.0491

p-value = P(z > 4.0491) = 0.0000

Since the p-value is less than the significance level of 0.05, we reject the null hypothesis and conclude that there is evidence to suggest that the proportion of individuals who caught pertussis and were not up to date on their booster shot is higher than those that were.

Step-by-step explanation:

The midsegments of AABC, hypotenuse BC  is B. 15.

In a triangle, a midsegment is a line segment that connects the midpoints of two non-adjacent sides of the triangle. In this figure, DE and DF are the midsegments of AABC, which means that they connect the midpoints of the sides AB and AC, respectively. Since DE and DF are parallel, we know the triangle isosceles (both legs are congruent).

Since the angle at A is 122°, we know that the angle at B and C are 78° (180-122=58). Therefore, if we draw the altitude from B to AC, we have a 30-78-72 triangle. We have been given the length of the altitude, 8, and the angle of the base, 72. We can use the Sine Ratio to calculate the hypotenuse, BC.

sin(72) = opposite / hypotenuse = 8/BC

Solving for BC, we get 15
