The percentage that Richard get is 8%

The statement can be interpreted as:

He answered 52 correctly from a total of 65 questions

From the above statement, we have the following parameters

Dividend = 52

Divisor  = 65

The percentage is then calculated as

Percentage = Dividend/Divisor  x 100%

Substitute the known values in the above equation

So, we have

Percentage = 52/65 x 100%

Evaluate the quotient

Percentage = 0.8x 100%

Evaluate the product

Percentage = 8%

Hence, the percentage is 8%

Step-by-step explanation:

The temperature of the hottest day in Oklahoma in Celsius to the nearest tenth of a degree is 48.89 degrees.

The process of converting a temperature value from one unit to another is known as temperature conversion. On scales like Kelvin, Celsius, Fahrenheit, etc., we measure temperature. The freezing point and boiling point of water, respectively, are 273.15K and 373.15K on the Kelvin scale. The freezing point and boiling point of water, respectively, are 32°F and 212°F on the Fahrenheit scale. The freezing point and boiling point of water, respectively, are 0°C and 100°C on the Celsius scale.

Given, The hottest day recorded in Oklahoma was 120° Fahrenheit

F=(9/5)C+32

120=(9/5)C+32

(9/5)C=88

C=48.89

Therefore, the temperature of the hottest day in Oklahoma in Celsius to the nearest tenth of a degree is 48.89 degrees.

The  residual value is 0.6.

The estimated value of a fixed asset at the conclusion of its useful life or lease term is known as the residual value, also known as salvage value. In lease agreements, one of the lessor's main methods for figuring out how much the lessee must pay in periodic lease payments is the residual value.

Given:

y = 1.416x − 0.76

For (7, 8):

As, residual value = Measured value - Predicted value

or, residual value = (actual y-coordinate of the point) - (value of y from the

                                                                                                       equation)

When x = 10:

So, the value of y from the equation,

[tex]y_1[/tex] = 1.416 x 10 - 0.76

[tex]y_1[/tex]=  14.16 - 0.76

[tex]y_1[/tex]= 13.4

and, actual y-coordinate of the point, [tex]y_2[/tex]= 14

Residual value = 14 - 13.4

Residual value = 14 - 13.4

Residual value = 0.6

The ordered pair (5, −6) is a solution to the first and second equations because it makes both equations true.

In mathematics, a linear equation is one that may be written in the form where the variables are alphabets, and the coefficients are frequently real integers. An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.

The given system of equations is

x + y = -1          ......(1)

3x - y = 21       ......(2)

Rewrite equation (1)

y = - x - 1        ......(3)

Put equation (4) in equation (3)

3x -(-x -1) = 21

3x + x + 1 = 21

4x = 20

x = 20/4

x = 5

Put x= 5 in equation (3)

y = - 5 - 1

y = - 6

So, both the options are correct, (5, -6) is the solution of both equations.

Answer: Diverge Reasoning I took the test

Answer:

Step-by-step explanation:

Let y be the distance the car travels, in miles.  Let t be the time traveled, in hours.  The speed is 45 m/h.  We know that the distance the car travels is given by the equation:

Distance = (speed)*(time)

Using the assigned variables, we can rewrite this as:

   d(t)  = (45 m/h)(t hours)

We want an equation that will tell us the position of the car, y, at any time, t, including t = 0, the start.  

d(t) = ?

At time = 0, the starting point of the car is P.  We can write:

d(0) = P

For x[tex]\geq[/tex]0, we would find the car at:

     d(t) = P + (45)*t

The 45 is in units of miles/hour,  t is in hours and d is in miles.  Let's assume an intital position, P, for this car to be 10 miles.  P = 10 miles.

The function is:  d(t) = 10 + (45)*t

If we leave the units in, it can be written as:  d(t) = (10 miles) + (45 miles/hr)*t(in hr)

We can see that the term "(45 miles/hr)*t(in hr)" will eventually reduce to just miles one we enter the time in hours, since the hours cancel out.

The graph of this function is attached.   The line crosses the y axis at 10 (miles) when time, t, is 0 : the car has not started.  

The slope of the graph can be determined by calculating the Rise/Run of the line.  Pick any two points.  I'll choose:  (2,100) and (4,190).

 Rise (change in y) is (190-100) = 90

 Run (change in x) is (4 - 2) = 2

Slope = Rise/Run = (90/2) or 45.

The slope has the same value as the speed, as it should.  The slope is telling us the rate of change, which for this graph, is the speed of the car.  The y-intersect is (0, 10).  The car is at 10 miles at the start (t=0).

To create a scenario where could have a negative value requires some imagination.  There is really no such thing as negative time, except in time travel movies.  But we can define t, perhaps, as the start of a race.  (High noon, for example).  If the cars were allowed to start moving before noon as long as they started back (negative direction) from the starting point of the race.  If t is defined as "hours after 12:00 noon" then a value of t = -1  means 11:00 AM.  If the car were approaching the staring line at 45 miles/hour, ahread of the official start time, the graph would make sense.  Not the race, so much, but the graph would be accurate.

The newly translated function of  f(x) = 7x + 1 is; g(x) = 7(x - 1) + 1

In transformation of functions, there are different operations such as translation, reflection, dilation, rotation.

Now, we are told that the function is given as;

f ( x ) = 7x + 1

We are told that it is translated by 5 units to the right.

It is pertinent to note that when talking about translation, it is as good as saying moving from one point to the other without changing the dimensions or shape.

Now, when we shift a function f(x) = x - 1 by a units to the left, it means the translated function is; f'(x) = (x + 1) - 1

However, when we shift a function f(x) = x - 1 by a units to the right, it means the translated function is; f'(x) = (x - 1) - 1

The factor most likely results in the loss of genetic variation from a small population is called genetic drift.

Small populations tend to lose genetic variation at a faster rate than large populations due to genetic drift (stochastic sampling error). Genetic drift refers to the change in an existing gene variant frequency in the population due to random chance. Genetic drift may result in the disappearance of gene variants completely and thus decreases genetic variation. Furthermore, it could initially cause rare alleles to become much more frequent, and even fixed. The loss of some versions of a gene due to random chance is more likely to happen when populations are small.

Answer:

Step-by-step explanation:

And here is how to use it:

Example: simplify √12

12 is 4 times 3:

√12 = √(4 × 3)

Use the rule:

√(4 × 3) = √4 × √3

And the square root of 4 is 2:

√4 × √3 = 2√3

So √12 is simpler as 2√3

Another example:

Example: simplify √8

√8 = √(4×2) = √4 × √2 = 2√2

(Because the square root of 4 is 2)

And another:

Example: simplify √18

√18 = √(9 × 2) = √9 × √2 = 3√2

It often helps to factor the numbers (into prime numbers is best):

Example: simplify √6 × √15

First we can combine the two numbers:

√6 × √15 = √(6 × 15)

Then we factor them:

√(6 × 15) = √(2 × 3 × 3 × 5)

Then we see two 3s, and decide to "pull them out":

√(2 × 3 × 3 × 5) = √(3 × 3) × √(2 × 5) = 3√10

Fractions

There is a similar rule for fractions:

root a / root b  = root (a / b)

Example: simplify √30 / √10

First we can combine the two numbers:

√30 / √10 = √(30 / 10)

Then simplify:

√(30 / 10) = √3

Some Harder Examples

Example: simplify  

√20 × √5

√2

See if you can follow the steps:

√20 × √5

√2

√(2 × 2 × 5) × √5

√2

√2 × √2 × √5 × √5

Example: simplify 2√12 + 9√3

First simplify 2√12:

2√12 = 2 × 2√3 = 4√3

Now both terms have √3, we can add them:

4√3 + 9√3 = (4+9)√3 = 13√3

Here we see that 100 banks have been sampled.

a)

Probability = no. of favorable outcomes/total no. of outcomes

Here we see that under the row of Bank Fraud and Yes section there are

Hence,

n(A) = 10

n = 100

Therefore,

P(A) = 10/100

= 0.1

b)

The conditional Probability

P(X|Y) = P(X ∩ Y) / P(Y)

Here,

we need to find the bank is a fraud given that it is a private bank. Hence we need to find,

P(A|B)

= P(A ∩ B) / P(B)

Here we see that the private banks that are fraud are given to be 6.

Hence,

n(A ∩ B) = 6

Therefore,

P(A ∩ B) = 6/100

n(B) = 6 + 34 = 40

P(B) = 40/100
