You roll a standard number cube. Find P(number greater then 1)A6/5 B 5/6. C 1/6. D. 1

Answers

Answer 1

In a cube, there are six sides: just like a dice, the set of possibilities are {1, 2, 3, 4, 5, 6}.

In this case, the number of sample set is 6.

Hence the probability of getting a number greater than 1 is 5 .

That is from { 2, 3, 4, 5,6}; 5/6.

The answer to this problem is 5/6.

The correct option is B.

Total interest cost

Answers

Joe's monthly payment is $581.87, and the total interest cost of the loan is $110,675.20.

To calculate Joe's monthly payment, we can use the formula for a fixed-rate mortgage:

Monthly Payment = Loan Amount × Monthly Interest Rate / (1 - (1 + Monthly Interest Rate)^(-Number of Payments))

First, we need to calculate the loan amount. Since Joe put down 20%, the loan amount will be 80% of the home price:

Loan Amount = $140,000 × 0.8 = $112,000

Next, we need to calculate the monthly interest rate. The annual interest rate is 5.1%, so the monthly interest rate will be:

Monthly Interest Rate = Annual Interest Rate / 12 = 0.051 / 12 = 0.00425

Now, we calculate the number of payments. Joe obtained a mortgage for 30 years, which is equivalent to 30 × 12 = 360 monthly payments.

Using these values, we can calculate Joe's monthly payment:

Monthly Payment = $112,000 × 0.00425 / (1 - (1 + 0.00425)^(-360))

Using a financial calculator or spreadsheet software, we can evaluate this expression and find Joe's monthly payment to be approximately $581.87 (rounded to the nearest cent).

To calculate the total interest cost of the loan, we can subtract the loan amount from the total payments made over the 30-year period.

Total Interest Cost = (Monthly Payment × Number of Payments) - Loan Amount

Total Interest Cost = ($581.87 × 360) - $112,000

Using a financial calculator or spreadsheet software, we can evaluate this expression and find the total interest cost of the loan to be approximately $110,675.20 (rounded to the nearest cent).

Therefore, Joe's monthly payment is $581.87, and the total interest cost of the loan is $110,675.20.

The steps below show the incomplete solution to find the value of x for the equation
5x − 2x − 3 = −2 + 15:

Step 1: 5x − 2x − 3 = −2 + 15
Step 2: 5x − 2x − 3 = 13

Construct a free commutative monoid on an arbitrary (not necessarily finite) set?

Answers

Answer:

(M, +, ε)

Step-by-step Explanation

Let S be an arbitrary set. We can construct a free commutative monoid on S as follows:

Define M to be the set of all finite sequences of elements of S.

Define the binary operation on M as concatenation of sequences, denoted by +.

That is, for any two sequences
a = (a1, a2, ..., an) and b = (b1, b2, ..., bm), a + b is the sequence (a1, a2, ..., an, b1, b2, ..., bm).

Define the identity element of M as the empty sequence, denoted by ε.

That is, for any sequence a, ε + a = a + ε = a.

The resulting structure (M, +, ε) is a free commutative monoid on S.

To see why this is the case, note that every element of S can be identified with a sequence of length 1, and every element of M can be expressed as a concatenation of sequences of elements of S.

Moreover, the operation + is commutative, since concatenation of sequences is commutative, and the identity element ε acts as a neutral element for +.

Therefore, (M, +, ε) satisfies the axioms of a commutative monoid, and is a free object on the set S.

Lavilla is a famous resort in Italy. All of its rooms are always booked in the winter season. On average, 2800 skiers come to the resort every week (7 days). On average, skiers stay in Lavilla for 4 days. Each skier spends $40 daily in local restaurants. Question 1 (1 point) The average number of skiers in Lavilla is: _____________ [skiers].

Answers

Answer:

The average number of skiers in Lavilla are 1,600 skiers

Step-by-step explanation:

The number of skiers that come to Lavilla on average each week = 2,800 skiers

The number of days each skier stays in Lavilla = 4 days

The amount each skier spends in local restaurants daily = $40

According to Little's Law, we have;

L = λ·W

Where;

L = The average number of skiers in Lavilla

λ = The effective arrival rate of the skiers = 2,800 skiers per week arrive

W = The number of days each skier stays at Lavilla = 4 days = 4/7 week

The average number of skiers in Lavilla, 'L', is therefore, given as follows;

L = 2,800 skiers/weel × (4/7) week = 1,600 skiers

The average number of skiers in Lavilla, L = 1,600 skiers

The retail price of a television set is $4,500. If the buyer pays by cash, the price is 10% below the retail price. If the set is bought on higher purchase, the buyer pays a down payment of $675 and 24 monthly installments of $212.50. Calculate for the television the:

cash price to the buyer, if he pays by cash.
amount payable.
outstanding balance.
hire purchase price.
interest.
difference between the hire purchase and the cash price.
percentage interest charged.

Answers

Cash price to the buyer, if he pays by cash:

The cash price would be 10% less than the retail price of $4,500:

Cash price = $4,500 - (10% * $4,500)

Cash price = $4,500 - $450

Cash price = $4,050

Amount payable:

If the buyer chooses to purchase the TV on higher purchase, the amount payable would be the sum of the down payment and the total amount of monthly installments:

Amount payable = Down payment + (24 * Monthly installment)

Amount payable = $675 + (24 * $212.50)

Amount payable = $5,175

Outstanding balance:

The outstanding balance would be the difference between the amount payable and the down payment:

Outstanding balance = Amount payable - Down payment

Outstanding balance = $5,175 - $675

Outstanding balance = $4,500

Hire purchase price:

The hire purchase price would be the sum of the down payment and the outstanding balance:

Hire purchase price = Down payment + Outstanding balance

Hire purchase price = $675 + $4,500

Hire purchase price = $5,175

Interest:

The interest charged on the hire purchase would be the difference between the hire purchase price and the cash price:

Interest = Hire purchase price - Cash price

Interest = $5,175 - $4,050

Interest = $1,125

Difference between the hire purchase and the cash price:

The difference between the hire purchase price and the cash price would be the interest charged:

Difference = Interest

Difference = $1,125

Percentage interest charged:

To calculate the percentage interest charged, we can divide the interest by the hire purchase price and multiply by 100:

Percentage interest charged = (Interest / Hire purchase price) * 100

Percentage interest charged = ($1,125 / $5,175) * 100

Percentage interest charged = 21.74%

Therefore, the cash price to the buyer is $4,050, the amount payable is $5,175, the outstanding balance is $4,500, the hire purchase price is $5,175, the interest charged is $1,125, the difference between the hire purchase and the cash price is $1,125, and the percentage interest charged is 21.74%.

$155 $267 $284 $194 $299 $284 $287 $179 What is the mean, median, and mode of this data set?

Answers

Answer:

Mean = 243.625

Median = 275.5

Mode = 284

Each value is exact without any rounding.

=================================================

Original data set:

$155 $267 $284 $194 $299 $284 $287 $179

Let's remove the dollar signs, and separate each item with a comma:

155,267,284,194,299,284,287,179

Then sort the values from lowest to highest.

155,179,194,267,284,284,287,299

---------------------

To find the mean, we add up the values and divide by n = 8 since there are 8 items in the list.

(155+179+194+267+284+284+287+299)/8 = 243.625 is the mean

----------------------

Refer to the sorted data set.

The median is the middle-most value. Because the sample size n = 8 is even, we'll have two values tied for the middle.

n/2 = 8/2 = 4

The items in slot 4 and 5 are tied for the middle.

The values in slot 4 and 5 are 267 and 284 in that exact order.

Compute the midpoint: (267+284)/2 = 275.5 is the median

----------------------

The mode is the most frequent value. Look through the sorted data set to see that 284 shows up twice. This is the most frequent compared to the other values (that show up only once).

Therefore, the mode is 284

Side note: It's possible to have multiple modes. It's also possible to not have any modes at all.

Answers

Recall that two events are mutually exclusive if they cannot happen at the same time. In the given problem we are given that the probability of both events occurring is 0.5 therefore, the events are not mutually exclusive.

Now, two events are independent if one event happening does not affect the probability of the other, in the given problem the events don't affect each other, therefore, the events are independent.

Finally, to determine the probability of either event happening, we will use the following formula for not mutually exclusive events:

\(P(A\cup B)=P(A)+P(B)-P(A\cap B).\)

We know that:

\(\begin{gathered} P(A)=0.6, \\ P(B)=0.75, \\ P(A\cap B)=0.5. \end{gathered}\)

Morgan's supply of raisins is approximately 4.62 pounds.

What is the equivalent expression?

Equivalent expressions are expressions that perform the same function despite their appearance. If two algebraic expressions are equivalent, they have the same value when we use the same variable value.

Let's start by setting up an equation based on the given information:

14/48 + 38/48 = 5/x

Here, x represents the total supply of raisins in pounds.

To solve for x, we can first combine the fractions on the left-hand side of the equation:

52/48 = 5/x

Next, we can simplify by cross-multiplying:

52x = 48 x 5

52x = 240

Finally, we can solve for x by dividing both sides by 52:

x = 240/52

x ≈ 4.62

Considering only the values of θ for which the expression is defined, which of the following is equivalent to the expression below?
cos(−θ)⋅tan(−θ)⋅cscθ
Select the correct answer below:


−sinθ
1
sinθ
−1

Answers

The cos(θ) term cancels out and we are left with -1. Therefore, the equivalent expression is -1.

We can start by using the trigonometric identities:

cos(-θ) = cos(θ)

tan(-θ) = -tan(θ)

csc(θ) = 1/sin(θ)

Substituting these identities into the original expression, we get:

cos(θ) * (-tan(θ)) * (1/sin(θ))

Simplifying this expression, we can cancel out the cos(θ) and the sin(θ) terms:

-1 * cos(θ) * (1/(cos(θ))) The cos(θ) term cancels out and we are left with -1. Therefore, the equivalent expression is -1.

In other words, the original expression simplifies to -1 for all values of θ where it is defined (i.e. θ ≠ (2n + 1)π/2, where n is an integer). This means that as θ varies, the value of the expression will always be -1 when it is defined. Trigonometric identities are mathematical equations that involve trigonometric functions and are true for every possible value of the variables involved. There are various types of trigonometric identities, including:

Pythagorean Identities:

\(sin^2a + cos^2a= 1\\tan^2a + 1 = sec^2a\\1 + cot^2a = csc^2a\)

Angle Sum and Difference Identities:

sin(α±β) = sin α cos β ± cos α sin β

cos(α±β) = cos α cos β ∓ sin α sin β

tan(α±β) = (tan α ± tan β) / (1 ∓ tan α tan β)

Double Angle Identities:

sin 2θ = 2 sin θ cos θ

cos 2θ =\(cos^2\)θ - \(sin^2\)θ = 2 \(cos^2\)θ - 1 = 1 - 2\(sin^2\)θ

We have,

To find the product of 7 x 63 using the distributive property, we can break down 63 as the sum of its factors, such as 60 and 3:

7 x 63 = 7 x (60 + 3)

Now, we can apply the distributive property by multiplying 7 to each term inside the parentheses:

7 x (60 + 3) = 7 x 60 + 7 x 3

Simplifying further:

7 x 60 + 7 x 3 = 420 + 21

Therefore,

The product of 7 x 63 is 441.
