Which of the following expressions results in a positive number? Select three that apply.
A. -6 · (-3) · (-2)
B. -4 · (-3 - 1 )
C. -3 · (-8)
D. -3 · (-2 + 6)
E. 5 · (-1)
F. 6 · (4-2)

Answers

Answer 1

Answer: B, C, and F

Step-by-step explanation:

Answer 2

The expressions that result in a positive number will be -4 · (-3 - 1), -3 · (-8), and 6 · (4 - 2). Then the correct options are B, C, and F.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Simplify all the options, then we have

A. -6 · (-3) · (-2) = - 36

B. -4 · (-3 - 1 ) = 16

C. -3 · (-8) = 24

D. -3 · (-2 + 6) = - 12

E. 5 · (-1) = - 5

F. 6 · (4 - 2) = 12

The expressions that result in a positive number will be -4 · (-3 - 1), -3 · (-8), and 6 · (4 - 2). Then the correct options are B, C, and F.

Suppose the local Barons team wins every game they play with a probability of 0.75. What is the probability that the Barons would win a best-of-seven-game series (i.e., they play games until one team has won four game)?

Answers

Answer:

The probability is 0.173

Step-by-step explanation:

The probability is of winning is 0.75 = 75/100 = 3/4

This means that the probability of losing is 0.25 = 25/100 = 1/4

So if they are two win 4 games, they will lose three

We can get this probability using the Bernoulli approximation of the binomial theorem

So here, we have

P(X = 4) = 7 C 4 * 0.75^4 * 0.25^3

= 0.173034667969

which is approximately 0.1730

What is the sum of two consecutive numbers is 141

Answers

Two consecutive numbers can be written as:
x , x+1

So their sum being 141
x + x +1 = 141

Combine and solve for c

2x = 140
x = 70

So two numbers are:

70,71

The two consecutive integers such that their sum is 141 will be 70 and 71.

What is a number system?

The number system is a way to represent or express numbers.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Let's say that two consecutive integers are x and x + 1.

x + x + 1 = 141

2x + 1 = 141

2x = 140

x = 70

So, x + 1 = 71

Thus, it will be 70 and 71.

Hence "The two consecutive integers such that their sum is 141 will be 70 and 71".

Answer:

x = 0 x = -10

Step-by-step explanation:

First, use the AC method to figure out, what times what equals 0 and what adds up to equal 10, which would be 0 and 10.

Secondly, you would factor it out and be with

(x + 0)(x +10)=0

Third, you would set each one equal to 0

x + 10 = 0 x + 0 = 0

Solve from there to get your two x's

x = 0 and x = -10

2 free books

7 purchased books

=

? free books

21 purchased books

Compare the denominators.

2 free books

7purchased books

To get from 7 to 21, multiply by 3. Multiply the numerator and denominator by 3 to find the number of free books Larry got.

2 free books3

7 purchased books3

=

6free books

21 purchased books

Larry got 6 free books.

Lerry will get 6 free books . Because she gets 2 free books for every 7 purchased books.
