If Mr. Bisby wants to know the average of the grades on a test, what measure of central tendency would he be looking at?

(Spelling counts so make sure to spell it correctly)

Answer:

A.

Step-by-step explanation:

If you put the x value of the table and use it in each equation, only one gives the y output on the table.

y=x + 4

5=1 + 4

6=2+4

7=3+4

8=4+4

9=5+4

The correct option is A) y=x+4

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here option A as y=x+4 now lets verify this option

if x=1 then y = 1+4

                    = 5

Again if x=2 then y =2+4

                               =6

Similarly it can be clearly observed that all the values of y are 4 greater than the input of x given in the table.

Hence, option A is the correct answer.

Step-by-step explanation:

Because it's reflected across the x-axis, the x coordinate doesn't change. On the other hand, the y coordinate becomes its opposite. So we get:

it can be written like this, hope this helps: $15/hour <3

The hourly wage 15 dollars an hour as a fraction is $15/1hr.

A fraction represents a part of a number or any number of equal parts.

There is a fraction, containing numerator(upper value) and denominator(lower value).

When the numerator is less than the denominator, the fraction is called proper fraction, otherwise it is called improper fraction.

A proper fraction is also called fraction which is less than 1.

And an improper fraction is ≥ 1

A mixed fraction contains a sum of whole number and a proper fraction.

Answer:

Step-by-step explanation:

x is the quantity by which the original measurements of the garden is increased.  For example:  the original width is 5 ft and x is the amount by which this is increased.

x here is the added value in the width and length of his garden to increase the fencing.

A perimeter is a closed path that encompasses, surrounds, or outlines either a two-dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

Given that, Isaiah’s vegetable garden is 15 feet long by 5 feet wide.

He wants to increase the width and length of his garden and put a fence around it.

He writes an expression for the same, we need to find what is x here,

(x+15) + (x+5) + (x+15) + (x+5) is giving the perimeter of the farm after increasing the width and length of his garden,

So, simply we can say that, x here is the extra length and width.

The farmer added x to each width and the length to increase his fencing,

So, his new dimension will be = x+15 and x+5

So, the perimeter = 2(x+15+x+5)

Here, the perimeter is fencing =

= 2(x+15+x+5)

= x+15+x+5+x+15+x+5

Hence, x here is the added value in the width and length of his garden to increase the fencing.

Given:

The end points of a line segment are (4,0) and (12,0).

To find:

The midpoint of the line segment.

Solution:

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

The end points of a line segment are (4,0) and (12,0). So, the midpoint of the line segment is:

[tex]Midpoint=\left(\dfrac{4+12}{2},\dfrac{0+0}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{16}{2},\dfrac{0}{2}\right)[/tex]

[tex]Midpoint=\left(8,0\right)[/tex]

If 335 of these cars were parked with their bumpers touching, they would be almost exactly a mile long.

Answer:

The hardcover without a dust jacket.

Step-by-step Explanation

0.2 is 20%, so if you add that to the 64% you can see what the other percentage of books are. 64%+ 20% = 84. So if you subtract 84 from 100 that equals 16, so the other book percentage is 16%, which makes the hardcovers without a dust jacket the least number of books Patrick has.

Answer:

Adult=58

Step-by-step explanation:

c=child, a=adult

6.4c+9.7a=1145 equation 1

c+a=149 equation 2

a=149-c modified equation 2 to isolate a

6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2

6.4c+1445.3-9.7c=1145

-3.3c=-300.3

c=91

solve for a

c+a=149

91+a=149

a=58

Check answer:

6.4c+9.7a=1145

6.4(91)+9.7(58)=1145

582.40+562.60=1145

1145=1145

Since the calculated value of F=0.20  does not fall in the critical region

F ≥  = 3.481 we reject the alternate hypothesis and accept the null hypothesis and conclude that there is no difference between the means of the 3 treatments.

Step-by-step explanation:

Proportional is where everything will match

so we have 2x3=6 5x3=15 8x3=24 11x3=33

This works because it continues the same line of multiplication (x3).

But like B,  you start with 4,4=16 which works, but now you have 5x4=21, which will not work because 5x4 will never equal 21

Answer:

AB = 32

Step-by-step explanation:

Given:

AD = 40

CD = 9

Required:

Find the length of segment AB

Solution:

BC and CD are radius of the circle. Therefore,

BC = CD = 9

AB = AC - BC

AB = AC - 9

We need to find AC

Since AD is tangent, CD is perpendicular to AD, this means that <D is a right angle. This makes ∆ADC a right triangle.

Therefore, we can apply Pythagorean theorem to find AC.

Thus:

AC² = AD² + CD²

AC² = 40² + 9²

AC² = 1,681

AC = √1,681

AC = 41

Let's find BC:

AB = AC - 9

Plug in the value of AC

AB = 41 - 9

AB = 32
