Instead of finding the GCF, you can simplify with mental math.

If you notice they are both divisible by any number, divide them both by this number to simplify until they share no common factors.

252 and 288 are both divisible by 2.

252/288 = 126/144

126 and 144 are both divisible by 2.

126/144 = 63/72

63 and 72 are both divisible by 3.

63/72 = 21/24

21 and 24 are both divisible by 3.

21/24 = 7/8

A textbook has 500 pages on which typographical errors could occur. Suppose that there are exactly 10 such errors randomly locat

DiKsa [7]

Answer:

The probability of a selection of 50 pages will contain no errors is 0.368

The probability that the selection of the random pages will contain at least two errors is 0.2644

Step-by-step explanation:

From the information given:

Let q represent the no of typographical errors.

Suppose that there are exactly 10 such errors randomly located on a textbook of 500 pages. Let $\mu$ be the random variable that follows a Poisson distribution, then mean $\mu = \dfrac{10}{500}= 0.02$

and the mean that the random selection of 50 pages will contain no error is $\lambda = 50 \times 0.02 =1$

∴

$Pr(q= 0) = \dfrac{e^{-1} (1)^0}{0!}$

Pr(q =0) = 0.368

The probability of a selection of 50 pages will contain no errors is 0.368

The probability that 50 randomly page contains at least 2 errors is computed as follows:

P(X ≥ 2) = 1 - P( X < 2)

P(X ≥ 2) = 1 - [ P(X = 0) + P (X =1 )] since it is less than 2

$P(X \geq 2) = 1 - [ \dfrac{e^{-1} 1^0}{0!} +\dfrac{e^{-1} 1^1}{1!} ]$

$P(X \geq 2) = 1 - [0.3678 +0.3678]$

$P(X \geq 2) = 1 -0.7356$

P(X ≥ 2) = 0.2644

The probability that the selection of the random pages will contain at least two errors is 0.2644

18,19,20,21,23 please help me. I really need this answer.please help me.

Answer:

18. Supplementary

19. Vertical

20. x = 7

23. x = 25

Step-by-step explanation:

Use angle relationships to make equations which you can solve for x.

Example:

18. These two angles form a line. These are called supplementary.

19. These angles are across a vertex from each other and are equal or the same.

20. 9x + 1 = 7x - 9 + 5x - 11

9x + 1 = 12x - 20

9x - 9x + 1 = 12x - 9x - 20

1 = 3x - 20

1 + 20 = 3x - 20 + 20

21 = 3x

7 = x

23. These two angles are across a vertex from each other. This means the angles are equal. Think of it as a reflection. If you folded the paper on that vertex, the lines would be in the exact same place.

So set the two expressions equal to each other. Then use inverse operations to isolate x and solve.

5x + 4 = 8x - 71

5x - 5x + 4 = 8x - 5x - 71

4 = 3x - 71

4 + 71 = 3x - 71 + 71

75 = 3x

25 = x
