Which measurement is closest to the area of the triangle in square centimeters? A 63 cm2 B 42.75 cm2 С 35.5 cm2 D 31.5 cm2

Answers

Answer 1

The measurement shows that the base of the triangle is approximately 7 cm

while the height is approximately 9cm

The area of the triangle is given by

$\text{Area = }\frac{1}{2}\text{ x base x height}$$\begin{gathered} \text{Area =}\frac{1}{2}\text{ x 7 x 9} \\ \text{Area = }\frac{63}{2}cm^2 \\ \\ \text{Area = 31.5cm}^2 \end{gathered}$

An article claimed the state's typical price of a gallon of gasoline is $2.69. The prices from 5 gas stations surveyed were $2.79, $2.99, $2.69, $2.89, and $2.69.

According to this data, what is wrong with the article's statement?

Answers

This statement in the article is wrong because $2.69 is not the mean price ($2.81)

How to determine what is wrong with the data?

The prices from 5 gas stations surveyed are given as:

$2.79, $2.99, $2.69, $2.89, and $2.69.

There are no outliers in the dataset

So, the dataset can be summarized by the mean

The mean is

Mean = Sum/Count

So, we have

Mean = ($2.79+ $2.99+ $2.69+ $2.89+$2.69)/5

Evaluate

Mean = 2.81

The article quoted $2.69 as the typical price

This statement in the article is wrong because $2.69 is not the mean price ($2.81)

Answers

Answer:

absolutely convergent

Step-by-step explanation:

given data

sin(n)/3^n

solution

we have given term $\frac{sin(n)}{3^n}$

when n = 1

and we know that

value of sin(n) ≤ 1

so that we can say that

$\frac{sin(n)}{3^n}$ ≤ $\frac{1}{3^n}$ or $(\frac{1}{3})^n$

here $\frac{1}{3^n}$ is converges this is because common ratio in geometric series

here r is $\frac{1}{3}$ and here it satisfy that -1 < r < 1

so it is converges

and

$\frac{sin(n)}{3^n}$ is also similar

so it is converges

and here no $(-1)^n$ term is

so we can say series is absolutely convergent

Mofor has homework assignments in five subjects. He only has time to do two of
them.

Answers

The decision of which two homework assignments to complete depends on Mofor's individual circumstances and priorities.

If Mofor only has time to do two homework assignments out of the five subjects, he will need to choose which subjects to prioritize. The specific subjects he chooses to work on will depend on various factors such as his strengths, weaknesses, upcoming deadlines, and personal preferences. Here are a few strategies he could consider:

1. Prioritize based on importance: Mofor can prioritize the homework assignments that carry more weight in terms of grades or have upcoming deadlines. This way, he ensures that he completes the assignments that have a higher impact on his overall academic performance.

2. Focus on challenging subjects: If Mofor finds certain subjects more difficult or time-consuming, he can prioritize those assignments to allocate more time and effort to them. This approach allows him to concentrate on improving his understanding and performance in subjects that require extra attention.

3. Balance workload: Mofor can choose to distribute his efforts evenly across subjects, selecting two assignments from different subjects. This strategy ensures that he maintains a balanced workload and avoids neglecting any particular subject.

The decision of which two homework assignments to complete depends on Mofor's individual circumstances and priorities. It is essential for him to consider his academic goals, time constraints, and personal strengths to make an informed decision.

f(x) = x² - 5x + 66
f(x)= x2 + 5x - 66
F(x)=x2-5x - 66

Answers

The standard quadratic equation is (c) y = x² + 5x - 66

How to determine the quadratic equation?

From the question, we have the following parameters that can be used in our computation:

Zeros -11 and 6

This means that

x = -11 and x = 6

The quadratic equation can then be calculated as

y = (x - 6) * (x + 11)

Evaluate the products

y = x² - 6x + 11x - 66

Evaluae the like terms

y = x² + 5x - 66

Hence, the equation is y = x² + 5x - 66

consider a stick of length 1. we break it at a point which is chosen randomly and uniformly over its length and keep the piece that contains the left end of the stick. we then repeat the same process on the piece that we were left with. let y be the length of the piece that we are left with after breaking twice. find

Answers

The expected length of the piece that we are left with after breaking twice is L/4 and the variance Var(X) is 7L^2/144.

In the given question, consider a stick of length 1.

We break it at a point which is chosen randomly and uniformly over its length and keep the piece that contains the left end of the stick.

We then repeat the same process on the piece that we were left with.

We have to find expected length of the piece that we are left with after breaking twice.

In the same setting as Q7, suppose the length of the piece that we are left with after breaking twice is Y.

We also have to calculate the variance Var(Y).

Following Laws are used in the solution

Law of Iterated Expectations: E[X] = E[ E[X|Y] ]

& Law of total variance: Var(X) = E[Var(X|Y)]+Var(E[X|Y])

Now, Y = Length of the stick after we break it the first time

and X = length of the stick after we break it the second time

As both the distribution is uniformly distributed.

Now, E[Y] = L/2 and Var(Y)= l^2/12

E(x|y)[X|Y=y] = y/2 and Var(x|y)[X|Y=y] = y^2/12

As the expectation of uniform distribution over {a,b} is (b-a)/2 and variance is (b-a)^2/12

Using Law of Iterated Expectations

E[X] = E[ E[X|Y] ]

E[X] = E[ y/2 ]

E[X] = \int_{L}^{0}

E[X] = L/4

Now using Law of Total Variance

Var(X) = E[Var(X|Y)]+Var( E[X|Y] )

Var(X) = E[y^2/12]+Var(y/2)

Var(X) = (1/12)*E[Y^2]+(1/4)*Var(Y)

Var(X) = (1*12)*(Var[Y] + (E[Y])^2) + (1/4)*Var(Y)

Var(X) = (1/12)*(L^2/12+L^2/4) + (1/4)*(L^2/12)

Var(X) = 7L^2/144

How to determine the image of the dilation?

Dilation 1

The coordinates are given as:

A (5.5, 4.5), B (6, 2), C (3.5, 1.5), D (3, 4)

The scale factor of dilation is

k = 2

This means that we multiply the coordinates by 2.

So, we have:

A (11, 9), B (12, 4), C (7, 3), D (6, 8)

Dilation 2

The coordinates are given as:

A (-12, 24), B (-30, 0), C (-36, 36)

The scale factor of dilation is

k = 1/3

This means that we multiply the coordinates by 1/3.

So, we have:

A (-4, 8), B (-10, 0), C (-12, 12)

Dilation 3

The coordinates are given as:

A (3, -5), B (3, -2.5), C (0, -4), D (0, -2)

The scale factor of dilation is

k = 2

This means that we multiply the coordinates by 2.

So, we have:

A (6, -10), B (6, -5), C (0, -8), D (0, -4)

Use this formula to calculate compound interest:

Interest Rate = 4%

Time= 5 years

Using the information above, how much money would you have after 5 years? Choose the answer that is closest to the exact answer.

Answers

The amount after 5 years on $100 using the compound interest is $122.

According to the question,

We have the following information:

Principal = $100

Interest Rate = 4%

Time= 5 years

We know that the following formula is used to find the total amount if there is compound interest:

Compound amount = $P(1+\frac{r}{100})^{t}$ where P is the principal, r is interest rate and t is the time in years

(Note that there are different formulas for compound interest depending on how it is calculated.)

A = $100(1+\frac{4}{100})^{5}$

A = $100(\frac{104}{100})^{5}\\100(1.04})^{5}$

A = 100*1.22

A = $122

Hence, the amount after 5 years on $100 using the compound interest is $122.

Fill in the missing numbers below.

5 feet + 12 inches = blank
yard(s)

Blank inches = 1 foot + 1 yard

Blank feet = 3 feet + 24 inches

Answers

Answer:

5 feet + 12 inches = 2 yards

48 inches = 1 foot + 1 yard

5 feet = 3 feet + 24 inches

Step-by-step explanation:

To help solve these equations, you must know how to convert feet to inches, inches to yards, etc. Use the information below:

1 feet = 12 inches

3 feet = 1 yard

To solve 5 feet + 12 inches = blank yard(s), convert 5 feet & 12 inches to yards. Since 5 feet would be complicated to convert, let's convert 12 inches to feet first.

12 inches = 1 feet

Instead of 12 inches, we can substitute it as 5 feet + 1 feet = blank yard(s). That would be 6 feet = ? yards. 3 feet = 1 yard, which tells us we must divide both sides by 3. Thus, 5 feet + 12 inches = 2 yards.

Blank inches = 1 foot + 1 yard

To find the # of inches in a yard, you must first know that 3 feet = 1 yard. If there are 12 inches in a foot, we must multiply 3 by 12, getting us 36. You add 12 inches (1 foot), getting us 48 inches in total. Thus 48 inches = 1 foot + 1 yard.

Blank feet = 3 feet + 24 inches

Since 3 feet is already feet, we do not need to convert it. If 12 inches is 1 foot, we must divide 24 inches by 12. So, there is 2 feet in 24 inches. 2 + 3 is 5. Thus, 5 feet = 3 feet +24 inches.
