C. - 1/8
D. 8

Answers

Answer 1
Answer:

Answer:

the answer is -1/ 8

Step-by-step explanation:

(−2−6)(23)

=(−1/64)(2x3)

=−1/64 (2x3)

2x2x2= 8

-1/64  8/8

Now you divide both sides by 8

-1/64 / 8/8= -1/8

So your answer is −1/8(C)

hope it helpsssssss :)

Step-by-step explanation:

Lois is 3 years older than Oscar. The sum of their ages is no more than 20. Write an inequality that can be used to represent this situation, where x represents Oscar’s age.

Answers

  • Let Oscar be x years old
  • Lois is x+3 years old

ATQ

\n \sf\longmapsto x+x+3\leqslant 20

\n \sf\longmapsto 2x+3\leqslant 20

\n \sf\longmapsto 2x\leqslant=17

\n \sf\longmapsto x\leqslant (17)/(2)

Answer:

let Oscar's years be x

• Oscar → x

• Lois → (x+3)

{ \rm{x + (x + 3) \leqslant 20}} \n \n { \boxed{ \rm{2x + 3 \leqslant 20}} }

The height of players on a football team is normally distributed with a mean of 74 inches, and a standard deviation of 1 inch. If there are 50 football players on the team, how many are less than 74 inches tall?

Answers

Answer:

Step-by-step explanation:

Let x be the random variable representing the height of players on the football team. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = standard deviation

n = number of samples

From the information given,

µ = 74 inches

σ = 1 inch

n = 50

x = 74 inches

the probability that a player is less than 74 inches tall is expressed as

P(x < 74)

For x = 74,

z = (74 - 74)/(1/√50) = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

Therefore,

P(x < 74)

The players less than 74 inches is

0.5 × 50 = 25 players
