The variable k can be expressed as follows:

k = 2D / f

A variable is a number represented by a letter in an equation or expression.

The variables in the given equation are D, f and k.

But we were asked to make the variable k the subject of the formula.

Therefore,

D = 1 / 2 f k

cross multiply

f k = 2D

divide both sides by f

Hence,

f k / f = 2D / f

k = 2D / f

Therefore, the variable k can be expressed as follows:

k = 2D / f

Answer:

x=7

Step-by-step explanation:

-8x+4=-52

First remove the four by subtracting 4 from -52

-8x= -56

Then, you would want the variable (x) by itself, so you divide by -8 (Dividing a negative by a negative makes a positive)

x=7

To confirm this answer is right, plug in 7 as the variable and make sure you get -52

(-8*7)+4= (-52)

Answer:

mean = 2.55

Standard deviation = 1.118

Step-by-step explanation:

Probability of babies who are boys

P = 0.51

Then we have q = 1-p

= 1-0.51

= 0.49

We have n = 5

We calculate the mean as:

np

= 0.51x5

= 2.55

Therefore mean = 2.55

The standard deviation

= √variance

= √npq

= √0.51x5x0.49

=√1.2495

= 1.118

According to the given statement the probability that the sum will be less than 3 or greater than 5 = 27/36.

Probability is simply the likelihood of something occurring. When we are uncertain about the result of an event, we might discuss the probabilities of several outcomes—how likely they are. Statistics is the study of occurrences guided by probability.

When two dice are rolled, the total number of possible outcomes is 36.

The fraction of gas the driver use in one week is 7/10 of a tank.

A fraction is a number which has a numerator and a denominator. such as 7/10

Numerator refers to the upper or top value. 7 is the numerator.

Denominator refers to lower or bottom value. 10 is the denominator.

Fraction of gas the driver use in one week = Fraction of gas used in a day × Number of days in a week

= 1/10 × 7

= (1 × 7) / 10

= 7/10 of a tank

Therefore, the fraction of gas the driver use in one week is 7/10 of a tank.

(4, 2) is the point after 270° rotation of point (-2,4)

Tradition holds that the reflection of point P across the line, denoted by the word P', is the "image" of point P. (pronounced "P prime"). Next to the aforementioned illustration, click "show distances." It is evident that the point P', which is the image of P, is by necessity on the same side of the line as P.

To find the image of a specific point after rotation of the point about its origin we will use the formula (y,-x)

so applying this formula we get the co-ordinates (4,2).

Answer:

x = 0

Step-by-step explanation:

6 ( x + 1 ) - 5x = 8 + 2 ( x - 1 )

6x + 6 - 5x = 8 + 2x - 2

-x = 0

x = 0

Answer:

x = 0

Step-by-step explanation:

First distribute both sides to simplify the equation

6(x +1) -5x = 8 + 2(x - 1)    =

6x + 6 - 5x = 8 + 2x - 2

Combine like terms

x + 6 = 6 + 2x

Subtract x from both sides

6 = 6 + x

Subtract 6 from both sides

0 = x

First we convert into slope-intercept form | y = mx + b

[tex]-3y=-3-x[/tex]

Move x to another side and subtract. (Whenever you move to another side, the sign/operator will be opposite. From plus to minus and from multiply to divide.)

Then move -3 to divide (-3-x)

[tex]y=\frac{-3-x}{-3}[/tex]

Separate - [tex]y=\frac{-3}{-3}-\frac{x}{-3}[/tex]

| Negative dividing Negative equal positive |

[tex]y=\frac{3}{3}-(-\frac{x}{3})[/tex]   | When the denominator is negative, we can pull out from the denominator and convert into the middle of fraction. |

| Negative multiplying Negative equal positive |

[tex]y=1+\frac{x}{3}[/tex]

This is not fully slope-intercept form yet. We swap the position of 1 and x/3

[tex]y=\frac{x}{3}+1[/tex]

There we go. The slope-intercept form.

Now our job is to find the x-intercept and y-intercept. First, know what m and b represents in the equation y = mx + b first.

From y = mx + b | m represents slope | b represents the y-intercept. |

Our equation is [tex]y=\frac{x}{3}+1[/tex]

Our m or slope is 1/3 and our y-intercept is 1. So we don't need to find the y-intercept because we've already found it.

Now move to finding x-intercept.

Substitute y as we get -

[tex]0=\frac{x}{3}+1[/tex]

Now whenever there is a denominator, multiply the whole equation by the denominator itself. As our denominator in this equation is 3, so we multiply all whole equation by 3.

[tex]0(3)=\frac{x}{3}(3)+1(3)\\0=x+3 \\x=-3[/tex]

Our x-intercept is x = -3 and y-intercept is y = 1.

Check the graph out. Our answers can be only A and B considering the slope is positive. C and D choices have negative slope (m < 0).

However, the value of slope also affects the graph. If the slope has a lot of value, then the graph will head to y-axis.

But if the slope has a little value then the graph will head to x-axis instead.

After all, when converting to the slope-intercept form. We don't need to find the x-intercept right away, just one glance at the graph along with the equation and we are able to answer it.

Thus, the answer is B choice.

I know it is a long, boring explanation. But providing a quality answer is what I'm trying to do. I may not be able to explain that good or whatever. But with an explanation, I hope it will benefit you someday, after all. An explanation can help you in a test. Thanks for reading and I hope this helps you.

The price in dollars per gallon is 4.02 dollars per gallons.

Gasoline costs 1.05 euro per litre in France.

The first thing to do is to determine the equivalent amount of the same litre in dollar while in France.

Then, equate it the quantity of litres to gallons.

Hence,

1 euro = 1.01 dollars

1.05 euro = ?

cross multiply

price  = 1.05 × 1.01

price = 1.0605 dollars

1 litres = 0.264172 gallons

Therefore,

cost =  1.0605 /  0.264172

cost  = 4.01552442257 dollars per gallons

cost  = 4.02 dollars per gallons

Therefore, the price in dollars per gallon is 4.02 dollars per gallons.
