antoniya [11.8K]

Answer:

5/10 or 1/2

Step-by-step explanation:

ratio=2:5:3

2+5+3=10 ( total of counters)

10=denominator

blue = ratio 5

5/10

or 1/2 simplified

3. Uniform A package delivery service breaks up its shipping charges into weight classes, where the package weights are uniforml

Tamiku [17]

Answer:

a) 50% of packages in this class would weigh less than 11 lbs.

b) 25% would weigh more than 11.5 lbs.

c) The average weight for a package in this class is 11 lbs.

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

For this problem, we have that:

a. Suppose one of the shipping classes is 10 to 12 lbs. What proportion of packages in this class would weigh less than 11 lbs?

Uniform distribution from 10 lbs to 12 lbs, this means that $a = 10, b = 12$ .

The answer is $P(X \leq 11)$ .

$P(X \leq 11) = \frac{11 - 10}{12-10} = 0.5$

50% of packages in this class would weigh less than 11 lbs.

b. What proportion would weigh more than 11.5 lbs?

Either a package weighs 11.5 lbs or less, or it weighs more than 11.5 lbs. The sum of the probabilities of these events is decimal 1. So:

$P(X \leq 11.5) + P(X > 11.5) = 1$

$P(X > 11.5) = 1 - P(X \leq 11.5)$

$P(X > 11.5) = 1 - \frac{11.5-10}{12-10}$

$P(X > 11.5) = 0.25$

25% would weigh more than 11.5 lbs.

c. What would the average weight for a package in this class be?

The mean M of the uniform distribution is:

$M = \frac{a+b}{2}$

So

$M = \frac{10+12}{2} = 11$

The average weight for a package in this class is 11 lbs.

The moon is about 240,000 miles from earth . What is the distance written as a whole number multiplied by a power of ten

Andreyy89

For this case we have the following number:

$240,000$

What we must do is rewrite the number as the product of two numbers.

We have then:

$240,000 = (24) (10000)$

From here, we write the number as the multiplication of a whole number and a power of base ten.

We have then:

$240,000 = (24) (10 ^ 4)$

Where,

$24$ : whole number

$10 ^ 4$ : power of base 10

Answer:

The distance written as a whole number multiplied by a power of ten is:

$(24) (10 ^ 4)$
