Answer: 5 feet 6 inches.

Step-by-step explanation:

12 inches = 1 foot

We can divided 66 by 12 to find how tall Joan is in feet.

66 ÷ 12 = 5.5

The term "0.5" means half, and there are 12 inches in a foot. So half of a foot would mean 6, so Joan's height would be 5 feet and 6 inches.

Joan is 66 inches tall, then the height of Joan in feet will be equal to 5.5 feet.

Multiplying or dividing by a numeric number, or more specifically, a correction factor, is a procedure comprising several steps known as conversion.

Rounding and choosing the appropriate number of significant digits may also be necessary steps in the procedure.

As per the given information in the question,

The given height of Joan = 66 inches

So, let's perform unit conversion,

1 foot  = 12 inches, so,

x foot = 66 inches

Use cross-multiplication,

12x = 66 × 1

x = 66/12

x = 5.5 feet.

Answer:

It will take 30.48 for the money in his account to double.

Step-by-step explanation:

Interest compounded anually:

With an investment of P, the amount compounded annualy after t years that you will have is given by:

[tex]A(t) = P(1+r)^{t}[/tex]

In which r is the interest rate, as a decimal.

Ren sets aside $1,000 into an online savings account with an annual interest rate of 2.3%

This means that [tex]P = 1000, r = 0.023[/tex]. So

[tex]A(t) = P(1+r)^{t}[/tex]

[tex]A(t) = 1000(1+0.023)^{t}[/tex]

[tex]A(t) = 1000(1.023)^{t}[/tex]

How long will it take for the money in his account to double?

This is t for which A(t) = 1000*2 = 2000. So

[tex]A(t) = 1000(1.023)^{t}[/tex]

[tex]2000 = 1000(1.023)^{t}[/tex]

[tex](1.023)^{t} = \frac{2000}{1000}[/tex]

[tex](1.023)^{t} = 2[/tex]

[tex]\log{(1.023)^{t}} = \log{2}[/tex]

[tex]t\log{1.023} = \log{2}[/tex]

[tex]t = \frac{\log{2}}{\log{1.023}}[/tex]

[tex]t = 30.48[/tex]

It will take 30.48 for the money in his account to double.

Answer:

x

Step-by-step explanation:

the variable that represents the cost per person is x

The cost per person for company A is given as: [tex]C = \dfrac{y-d}{x}[/tex] where C is cost per person and d is one time fixed delivery fee.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, let we take:

We're given that:

That means, as C is cost per person, so for x persons, it will be [tex]C \times x[/tex]

Thus, total cost = cost for x persons + delivery cost

or

[tex]y = C \times x + d\\\\[/tex]

Subtracting 'd' from both sides and then dividing both sides by 'x', we get

[tex]C = \dfrac{y-d}{x}[/tex]

Thus, the cost per person for company A is given as: [tex]C = \dfrac{y-d}{x}[/tex]where C is cost per person and d is one time fixed delivery fee.

Given the following expression:

To determine an estimate for each expression:

A fraction can be defined as a numerical quantity that is not expressed as a whole number. Therefore, a fraction is simply a part of a whole number.

Generally, a fraction comprises two (2) main parts and these include:

In this exercise, we would simplify and estimate the given expressions as follows:

Note: An estimate simply means an approximate value.

a. [tex]\frac{1}{8} + \frac{2}{5}=\frac{5+16}{40}=\frac{21}{40}[/tex]

For the estimate:

[tex]\frac{1}{8} + \frac{2}{5}=\frac{1}{2}[/tex]

b. [tex]\frac{13}{14} -\frac{1}{10}=\frac{130-14}{140} =\frac{116}{140} =0.83[/tex]

0.83 ≈ 1

c. [tex]\frac{1}{12} + \frac{1}{20}=\frac{5-3}{60} =\frac{2}{60} =0.03[/tex]

Answer:

0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: It weighs 2 lbs or more

Event B: Delivered by UPS

15% of the packages that are delivered by UPS weighs 2 lbs or more.

This means that [tex]P(A \cap B) = 0.15[/tex]

More than 2 lbs:

15% of 20%(UPS)

93% of 80%(Not delivered by UPS). So

[tex]P(A) = 0.15*0.2 + 0.93*0.8 = 0.774[/tex]

a. What is the probability that a package is delivered by UPS if it weighs 2 lbs or more

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.15}{0.774} = 0.1938[/tex]

0.1938 = 19.38% probability that a package is delivered by UPS if it weighs 2 lbs or more
