Answer:

22.75 .

Step-by-step explanation:

65 x 35  / 100 = 22.75.

The percentage expression 65% of 35 is 22.75

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

65% of 35

Express as products

So, we have the following representation

65% of 35 = 65% * 35

Express 65% as 0.65

So, we have the following representation

65% of 35 = 0.65 * 35

Evaluate the products

So, we have the following representation

65% of 35 = 22.75

Hence, the solution is 22.75

Answer:

The answer should be 2.

0 is the lowest number and then 2 would be lower quartile, The 4 would be the Median or the middle of all the data 7 is the upper quartile and 10 would be the highest number of absences.

To find the critical value t* for a t-distribution with 8 degrees of freedom, we need to use a t-table or a calculator with a t-distribution function. We want to find the value of t* such that the probability of getting a t-value greater than t* is 0.10 (or 10%).

Using a t-table, we can look for the row corresponding to 8 degrees of freedom and find the column that has a probability closest to 0.10. The closest probability in the table is 0.1002, which corresponds to a t-value of 1.859. Therefore, the critical value t* for a t-distribution with 8 degrees of freedom and a probability of 0.10 to the right of t* is approximately 1.859.

Alternatively, we can use a calculator with a t-distribution function to find the critical value. We can input the degrees of freedom (8) and the probability to the right of the critical value (0.10) into the calculator. The result is approximately 1.859.

In conclusion, the critical value t* for a t-distribution with 8 degrees of freedom and a probability of 0.10 to the right of t* is approximately 1.859.

Answer:

t ≈ 16.0 units

Step-by-step explanation:

Using the Sine rule in Δ TUV , that is

\(\frac{t}{sinT}\) = \(\frac{v}{sinV}\) , substitute values

\(\frac{t}{sin135}\) = \(\frac{11}{sin29}\) ( cross- multiply )

t sin29° = 11 sin135° ( divide both sides by sin29° )

t = \(\frac{11sin135}{sin29}\) ≈ 16.0 ( to the nearest tenth )

Answer:

The weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.

Step-by-step explanation:

Let the weight of the gaming machine be x and that of DVD be y. ATQ,

3x+y = 48 .....(1)

3x+5y = 72 .....(2)

Subtract equation (2) from (1)

3x+y-(3x+5y) = 48 -72

y-5y = -24

-4y = -24

y = 6

Put the value of y in equation (1).

3x+6 = 48

3x = 42

x = 14

So, the weight of each gaming machine be 14 pounds and that of DVD is 6 pounds.

Answer:

DVD box weighs 6 pounds and gaming machine box weighs 14 pounds

Given the earth's surface area that is suitable to live on, the area that will be owned by each person on earth is approximately 5.12 × 10⁻³ mi² per person.

The earth has a spherical shape. The surface area of a sphere is measured using the equation;

A = 4πr²

Where r is radius and π is constant pi ( π = 3.14 )

Given the data in the question;

First we calculate, the surface area of the earth.

A = 4πr²

A = 4 × 3.14 × ( 3959 mi )²

A = 4 × 3.14 × ( 3959 mi )²

A = 1.97 × 10⁸mi²

Next, we calculate the percentage of the earth surface that is suitable to live on.

20% of surface area

20% of 1.97 × 10⁸mi²

20/100 × 1.97 × 10⁸mi²

3.94 × 10⁷mi²

The percentage of the earth surface that is suitable to live on is 3.94 × 10⁷mi²

Next we divide the suitable surface area by the number of people on earth.

= ( 3.94 × 10⁷mi² ) ÷ ( 7.7 × 10⁹ )

= 5.12 × 10⁻³ mi² per person

Given the earth's surface area that is suitable to live on, the area that will be owned by each person on earth is approximately 5.12 × 10⁻³ mi² per person.

Descriptive statistics :-

These are operations which are used to summarize certain characteristics a set of data has.

Descriptive statistics can be defined as a field of statistics that is used to summarize the characteristics of a sample by utilizing certain quantitative techniques.

It helps to provide simple and precise summaries of the sample and the observations using measures like mean, median, variance, graphs, and charts.

Univariate descriptive statistics are used to describe data containing only one variable. On the other hand, bivariate and multivariate descriptive statistics are used to describe data with multiple variables.

Mean and range deals with the full set of data while interquartile range measures just the middle half of the data and is denoted as option A.

The chance of x 92 is the best option since it corresponds to the shaded area under a normal distribution with a mean of 100 and a standard deviation of 5.

Identify the mean (μ) and standard deviation (σ),

Here,  mean μ = 100, standard deviation σ = 5
Recognize that x = 92 is within the shaded region of normal distribution, so the probability we're looking for is either x ≤ 92 or x ≥ 92.
Since the shaded region is to the right of 92, the best choice is the probability of x ≥ 92.

The ratio of the number of unshaded to shaded squares is 7 : 3.

Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.

It is also defined as the fraction of one quantity with respect to other.

The ratio of a and b is denoted as a : b.

Given is a grid of squares which is given below.

Total number of squares = 10

Of that,

Number of shaded squares = 3

Number of unshaded squares = 7

We have to find the ratio of unshaded to shaded squares in the grid which is 7 / 3 or 7 : 3.

Ratio of unshaded squares to shaded squares = 7 : 3

  3(x-8)(x+5)

Step-by-step explanation:

You want to factor the quadratic 3x² -9x -120.

Each of the coefficients is divisible by 3, so that is the first thing we can factor out:

  = 3(x² -3x -40)

To factor the quadratic, we need factors of -40 that have a sum of -3.

  -40 = -40(1) = -20(2) = -10(4) = -8(5)

The last of these factor pairs have a sum of -3, so the factorization is ...

  = 3(x -8)(x +5)

__

Additional comment

The product of factors (x+a) and (x+b) is ...

  (x +a)(x +b) = x² +ax +bx +ab = x² +(a+b)x +ab

This is why we're looking for factors of -40 = ab, that have the sum (a+b) = -3.

The equation shows that there are 30 books on the shelf.Let's assume the total number of books on the shelf is represented by 'x'.

We are given that the 12 paperback mysteries account for 40% of the books on the shelf.

Since 40% is equivalent to the decimal value 0.40, we can set up the equation :we get

0.40 * x = 12

To solve for 'x', we divide both sides of the equation by 0.40:

x = 12 / 0.40

Simplifying  the equation:

we get ,

x = 30

the account balance can change quickly and frequently based on transactions and fees, so it's important to keep track of your transactions carefully and reconcile your account regularly to ensure that you have an accurate balance.

Unfortunately, there is no checkbook or transaction provided in your question. Without knowing the details of the transaction and the starting balance, it is not possible to determine the account balance on January 28.
However, I can provide some general information on how to calculate account balances based on transactions in a checkbook. To determine the account balance at any given point in time, you need to start with the starting balance (which is typically the balance on the previous statement) and then add or subtract the transactions that have occurred since that time.
To do this, you would need to look at the transactions in the checkbook and classify them as either deposits or withdrawals. Deposits are amounts of money that have been added to the account, while withdrawals are amounts of money that have been taken out of the account.
For each deposit, you would add the amount to the starting balance. For each withdrawal, you would subtract the amount from the starting balance. Once you have gone through all the transactions, the resulting amount should be the account balance.
