Joan is 66 inches tall.What is Joans height in feet?
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.
What is Unit conversion?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.

Suppose that out of 20% of all packages from Amazon are delivered by UPS. 15% of the packages that are delivered by UPS weighs 2 lbs or more. Also, 7% of the packages that are not delivered by UPS weighs less than 2 lbs. a. What is the probability that a package is delivered by UPS if it weighs 2 lbs or more
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

molly is comparing two different food companies to provide food for her banquet. The total cost, y, includes a one-time delivery fee and an additional fee based on the number of people, x, who attend the banquet. What is the cost per person for Company A
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.
How to form mathematical expression from the given description?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:
C = cost per person for company Ad = one-time delivery feeWe're given that:
y = total cost x = number of people, who attend the banquet.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.

Answer:
[tex]m\angle BCD = 32^{\circ}[/tex]
Step-by-step explanation:
Given

See attachment for basketball blackboard
Required
Find [tex]m\angle BCD[/tex]
In the attachment:
[tex]m\angle BCD[/tex] and [tex]m\angle DAB[/tex] are opposite angles
And in a parallelogram, opposite angles have the same measure.

[tex]m\angle BCD = 32^{\circ}[/tex]
Ren sets aside $1,000 into an online savings account with an annual
interest rate of 2.3%, compounded annually. How long will it take for the
money in his account to double?
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.
