l) \(P(not C)=\frac{2}{3}\)

Yes, events A and B are mutually exclusive. Because the results can either be even or odd, not both. No, events B and C are not mutually exclusive because the result can be both, odd and prime.

Step-by-step explanation:

a)

In order to solve part a of the problem, we need to find the possible outcomes, in this case, the possible outcomes are:

{3,5}{3,10} and {5,10}

We could think of the oppsite order, for example {5,3}{10,3}{10,5} but these are basically the same as the previous outcomes, so we will just take three outcomes in our sample space. We can think of it as drawing the two chips at the same time.

b)

Now the probability of the sum of the chips to be even. There is only one outcome where the sum of the chips is even, {3,5} since 3+5=8 the other outcomes will give us an odd number, so:

\(P=\frac{#desired}{#possible}\)

\(P(A)=\frac{1}{3}\)

c) For the probability of the sum of the chips to be odd, there are two outcomes where the sum of the chips is odd, {3,10} since 3+10=13 and {5,10} since 5+10=15 the other outcomes will give us an even number, so:

\(P(B)=\frac{2}{3}\)

d) The probability of the sum of the chips is prime. There is only one outcome where the sum of the chips is prime, {3,10} since 3+10=13 the other outcomes will give us non prime results, so:

\(P(C)=\frac{1}{3}\)

e) The probability of the sum of the chips to be even and prime. There are no results where we can get an even and prime number, since the only even and prime number there is is number 2 and no outcome will give us that number, so:

P(A and C)=0

f) The probability of the sum of the chips is even or odd. We can either get even or odd results, so no matter what outcome we get, we will get an odd or even result so:

\(P(A or B)=1\)

g) The probability of the sum of the chips is odd and prime. There is only one outcome where the sum of the chips is odd and prime, {3,10} since 3+10=13 the other outcomes will give us non prime results, so:

\(P(B and C)=\frac{1}{3}\)

h) The probability of the sum of the chips is even or prime. There are two outcomes where the sum of the chips is even or prime, {3,10} since 3+10=13 and {3,5} since 3+5=8 so:

\(P(A or C)=\frac{2}{3}\)

i) The probability of the sum of the chips is prime given that the sum of the chips is odd. There are two possible results where the sum of the chips is odd {3,10} and {5,10} and only one of those results is even, {3,10}, so

\(P(C given B)=\frac{1}{2}\)

j) The probability of the sum of the chips is prime given that the sum of the chips is even. There is only one possible even result: {3,5} but that result isn't prime, so

\(P(C given A)=0\)

k) The probability of the sum of the chips is not odd. There is only one outcome where the sum of the chips is not odd (even), {3,5} so:

\(P(not B)=\frac{1}{3}\)

l) The probability of the sum of the chips is not prime. There are two outcomes where the sum of the chips is not prime, {3,5} and {5,10} so:

\(P(not C)=\frac{2}{3}\)

Are events A and B mutually exclusive?

Yes, events A and B are mutually exclusive.

Why or why not?

Because the results can either be even or odd, not both.

Are events B and C mutually exclusive?

No, events B and C are not mutually exclusive.

Why or Why not?

Because the result can be both, odd and prime.

This year, the number of raffle tickets sold for a school's extracurricular activities fundraiser is 848. It is estimated that the number of raffle tickets sold will increase by 5% each year.

The total number of raffle tickets sold at the end of 9 years is approximately 9,818.  

To find the total number of raffle tickets sold at the end of 9 years, we need to calculate the number of tickets sold each year and sum them up.

Starting with the initial number of tickets sold, which is 848, we will increase this number by 5% each year for a total of 9 years.

Year 1: 848 + (5% of 848) = 848 + 42.4 = 890.4

Year 2: 890.4 + (5% of 890.4) = 890.4 + 44.52 = 934.92

Year 3: 934.92 + (5% of 934.92) = 934.92 + 46.746 = 981.666

Year 9: Ticket sales at the end of 9 years = Number of tickets sold in Year 8 + (5% of Year 8 sales)

Year 9: Total = 1,399.585 + 69.97925 = 1,469.56425 ≈ 1,469.56

The total number of raffle tickets sold at the end of 9 years is approximately 1,469.56.

The correct option is 9,818.

Answer: 1386 sq.cm.

Step-by-step explanation:

2Pi r= 132

2 * 22/7 * r = 132

r = 21

Area = pi * r * r

= 22/7 * 21 * 21

= 1386 sq.cm.

Hope this helps :))

The system of inequalities is:

5x + 10y ≥ 900 (total ticket sales must be at least $900)

x + y ≤ 130 (total number of tickets sold must be at most 130)

One possible solution is x = 70 (student tickets) and y = 60 (adult tickets).

To write a system of inequalities based on the given information, we can consider the revenue from ticket sales and the seating capacity of the auditorium:

Let x represent the number of student tickets sold, and y represent the number of adult tickets sold.

Revenue inequality:

The drama club must make no less than $900 from ticket sales, so the revenue equation is: 5x + 10y ≥ 900. This equation ensures that the total revenue from ticket sales is at least $900.

Seating capacity inequality:

The auditorium can hold at most 130 people, so the total number of tickets sold cannot exceed this limit: x + y ≤ 130.

To solve this system of inequalities graphically, we plot the inequalities on a graph. The shaded region where the inequalities overlap represents the feasible region or the possible solutions.

One possible solution within this feasible region could be x = 70 (student tickets) and y = 60 (adult tickets). This combination satisfies both inequalities and fulfills the revenue requirement of at least $900.

The image coordinates of K′ if the preimage is reflected across y = −7 is (-4, -8)

Based on the given question, we have certain variables that can be utilized for our calculations.

K = (-4, -6)

First, find the equation of the reflection line

The reflection line is y = -7.

This can be expressed as

y = a = -7

The image of the reflection is then calculated as

K' = (x, -(y + 2|a|))

Replace the given or established values in the equation mentioned earlier, resulting in the following expression

K' = (-4, -(-6 + 2 * 7))

The fraction that bears the same ratio to 1/27 as 3/7 does to 5/9 is 27/35.

To find the fraction that bears the same ratio to 1/27 as 3/7 does to 5/9, we can set up a proportion.

Let's represent the unknown fraction as x. The ratio can be configured as follows:

x / (1/27) = (3/7) / (5/9)

To solve this proportion, we can cross-multiply:

(x * 5/9) = (3/7) * (1/27)

Simplifying the right side:

(x * 5/9) = 3/189

To eliminate the fraction on the left side, we can multiply both sides by the reciprocal of 5/9, which is 9/5:

(x * 5/9) * (9/5) = (3/189) * (9/5)

Simplifying further:

x = 27/35

Therefore, the fraction that bears the same ratio to 1/27 as 3/7 does to 5/9 is 27/35.

Double Check: 100% - 77% = 23% or 0.23

596 × 0.23 = 137.08

137.08 + 458.92 = 596

The measure of <BDC is 68 degree.

The fundamental characteristics listed below make it simple to recognise parallel lines.

First, Interior of ( 2y+ 34) = 180 - (2y + 34)

                                         = 146- 2y

Now, using Corresponding Angle

74 = 146 - 2y

2y= 72

y= 72 / 2

y= 36

Second, Using Linear Pair

-7x+ 12 + (-8x+ 48)= 180

-7x + 12 - 8x + 48 = 180

-15x + 60 = 180

Answer:

Area of ΔQRS = 2.3 square inches

Step-by-step explanation:

From the given information,

<S + <Q + <R = \(180^{o}\)

51 + 44 + <R = \(180^{o}\)

95 + <R = \(180^{o}\)

<R = \(180^{o}\) - 95

    = \(85^{o}\)

<R = \(85^{o}\)

Applying the Sine rule, we have;

\(\frac{q}{SinQ}\) = \(\frac{r}{SinR}\) = \(\frac{s}{SinS}\)

Using \(\frac{r}{SinR}\) = \(\frac{s}{SinS}\)

\(\frac{r}{Sin 85}\) = \(\frac{2.3}{Sin51}\)

r = \(\frac{2.3*Sin85}{sin51}\)

  = 2.9483

r = 2.9 inches

Also, \(\frac{q}{SinQ}\) = \(\frac{s}{SinS}\)

\(\frac{q}{Sin44}\) = \(\frac{2.3}{Sin51}\)

q = \(\frac{2.3*Sin44}{Sin51}\)

  = 2.0559

q = 2.0 inches

From Herons formula,

Area of a triangle = \(\sqrt{s(s-q)(s-r)(s-s)}\)

s = \(\frac{2.3 + 2.0 + 2.9}{2}\)

  = 3.6

Area of ΔQRS = \(\sqrt{3.6(3.6-2.0(3.6-2.9)(3.6-2.3)}\)

                        = 2.2895

Area of ΔQRS = 2.3 square inches
