Answer:

Solution in photo

Step-by-step explanation:

Answer:

a) 0.24

b) 0.3

Step-by-step explanation:

Given the following probability

P(A) = 0.4 P(B) = 0.6

a) P(A and B) =P(A)P(B) {Independent)

P(A and B) = 0.4×0.6

P(A and B) = 0.24

b) Given P(A | B) = 0.5, this is a conditional probability

If P(A | B) = P(A and B)/P(B)

Since If P(A | B) = 0.5

0.5 = P(A and B)/P(B)

P(A and B) = 0.5(P(B)

P(A and B) = 0.5(0.6)

P(A and B) = 0.3

Answers

Answer:

1). Area = 37 cm²

2). Area = 120 cm²

Step-by-step explanation:

Figures in the picture attached are the examples of composite figures.

1). Area of the composite figure = Area of rectangle A + Area of rectangle B

   Since area of rectangle = Length × width

   Area of rectangle A = 8 × 2 = 16 cm²

   Area of rectangle B = 3 × 7 = 21 cm²

   Area of the composite figure = 16 + 21 = 37 cm²

2). Area of the composite figure = Area of C + Area of D

                                                     = (3×4) + (9×12)

                                                     = 12 + 108

                                                     = 120 cm²

see picture below:

Answers

Answer:

Novak doesn't have enough sheets of paper left to print any magazines.

Step-by-step explanation:

The common shaded area represents the range of all combinations that fit both Novak's wish to print at least 40 books and magazines and the limit of 3600 sheets of paper.

Can you find the combinations within that area where the number of books Novak prints is 30?

Hint #2 / 3

The line K = 30K, represents all combinations where the number of books Novak prints is 30. We can see that the points on that line do not lie within the common shaded area.

Step-by-step explanation:

for the figure shown below, find the value of the variable and the measures of the angles.

x=
measure of angle P=
measure of angle Q=
measure of angle R=​

Answers

Answer:

p=58

q=84

r=38

Step-by-step explanation:

x+46+2x-18+x=180 degree ( angle sum property )

4x + 28 = 180 degree

4x = 180 - 28

4x = 152

x = 152 /4

x= 38

angle p = 2x -18 = 2 *38 -18 = 58 degree

angle q = x + 46 = 38 +46= 84 degree

angle r = x = 38 degree

Answer:

x= 38°

measure of angle P= 58°

measure of angle Q= 84°

measure of angle R=​38°

Step-by-step explanation:

Equations

The sum of the internal angles of a triangle is 180°. We are given the three angles as a function of x, thus:

2x - 18 + x + 46 + x = 180

Simplifying:

4x + 28 = 180

Subtracting 28:

4x = 180 - 28 = 152

x = 152/4 = 38

x = 38°

Angle P=2x-18=2*38-18=58°

Angle Q=x+46=38+46=84°

Angle R=x=38°

You randomly select one card from a 52-card deckFind the probability of selecting the eight of spades or the seven of hearts

Answers

A N S W E R :

A pack of 52 card deck.The 52 cards contains 13 spades and 13 hearts.

→ Probablity of getting the 8 spades = 1/52

→ Probablity of getting the 7 hearts = 1/52

Both are mutually exclusive event's.

So,

⇒ Probablity of getting 7 hearts or 8 spades = Probablity of getting the 7 hearts + Probablity of getting the 8 spades

⇒ Probablity of getting 7 hearts or 8 spades = 1/52 + 1/52

⇒ Probablity of getting 7 hearts or 8 spades = 2/52

Probablity of getting 7 hearts or 8 spades = 1/26

The probability of selecting the eight of spades or the seven of hearts is 1/26.

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Number of cards = 52

Number of eight of spades in the deck of cards  = 1

Number of seven of hearts in the deck of cards = 1

The probability of selecting the eight of spades or the seven of hearts.

= 1/52 + 1/52

= 2/52

= 1/26

Thus,

The probability of selecting the eight of spades or the seven of hearts is 1/26.

The largest prime number less than 100 is 97 by using the definition of prime number and examine the prime numbers that are smaller than 100.

To find the largest prime number less than 100,  to examine the prime numbers that are smaller than 100.

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.

Starting from 99 and moving downwards, check each number for divisibility by smaller numbers.

Any number that has divisors other than 1 and itself is not prime.

99 is not a prime number as it has more than one factors.

99 = 1, 3, 9, 11, 33, 99.

98 is not a prime number as it has more than one factors.

98 = 1, 2, 4, ........, 98.

 97 is a prime number as it has more than one factors.

97 = 1, 97.

solve the equation: the booster club of the baseball team bought pizza to sell at a concession stand. the school donated three pies to the sale. each pie was then cut into 8 pieces and sold . there were a total of 64 pieces to sell. how many pies did the booster club purchase

Answers

Answer:

they bought 5 pies

Step-by-step explanation:

.................

Five pies were bought by the booster club of the baseball team.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Three pies were provided for sale by the school. After that, each pie was divided into 8 pieces and sold. 64 pieces in all were available for purchase.

Let "p" be the number of pies the booster club purchased.

The school donated 3 pies, so the booster club purchased a total of p + 3 pies.

Each pie was cut into 8 pieces, so there were a total of (p + 3) × 8 = 64 pieces to sell.

This equation can be simplified to p + 3 = 8, or p = 5.

Therefore, there was a booster club that purchased 5 pies.
