Kai took five tests this semester. His scores are listed below.

92, 88, 90, 96, 84

What is the mean absolute deviation of Kai's test scores?In decimals

Answers

Answer:

3.2 0w0, hope this helps!

Step-by-step explanation:

I did this before

The mean absolute deviation of kai's test scores is 3.2.

What is mean absolute deviation?

The mean absolute deviation of a dataset is the average distance between each data point and the mean.

According to the given question

We have

the given data 92, 88, 90, 96, 84

For calculating mean absolute deviation

we will first calculate mean

mean = [tex]\frac{92+88+90+96+84}{5} =\frac{450}{5} = 90[/tex]

Now we will calculate the distance between each data point and the mean :

|92 -90| =2|88-90|  =2|90-90| =0|96-90| = 6|84 -90| = 6

Add the distances together

2+2+0+6+6 = 16

Divide the sum by number of data points.

MAD( mean absolute deviation ) = [tex]\frac{16}{5} =3.2[/tex]

Hence, the mean absolute deviation of Kai's test scores is 3.2.

The expression shown are 1. Monomial 2. Not a polynomial 3. Binomial 4. Trinomial 5. Not a polynomial 6. Binomial

What is Polynomial?

Polynomials are expressions of the form,

a₀ + a₁ x + a₂ x² + ................. + aₙ₋₁ xⁿ⁻1 + aₙ xⁿ

where a's are the coefficients, x is the variable and n is the number of terms.

1. 36

36 can be written as 36 x⁰.

This is a constant polynomial.

Since there is only one term, it is monomial.

2. [tex]\frac{3}{q^{2} }[/tex] + 5

This can be written as 3 q⁻² + 5.

The exponent of the variable is not a whole number, so is not a polynomial.

3. 7x - x + 5

This can be written as 6x + 5.

This is a polynomial and is binomial since there are two terms.

4. 8g²h - 7gh + 2

This is a polynomial in two variables.

This is a trinomial, as there are three terms.

5. [tex]\frac{1}{4y^{2} }[/tex] + 5y - 8

This can be written as 1/4 y⁻² + 5y - 8

This is not  a polynomial as the exponent is not a whole number.

6. 6x + x²

This is a polynomial.

It is a binomial.

Hence four of the expressions shown are polynomials.

Using the graph, determine the coordinate of the y-intercept of the parabola.

Answers

Answer:

Step-by-step explanation:

The parabola intercepts at 8 on the y axis, and since the interception has zero x value, x=0.

The graph the coordinate of the y-intercept of the parabola is (0, 8).

What is Intercept?

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

When you know the slope of the line to be investigated and the given point is also the y intercept, you can utilise the slope intercept formula, y = mx + b. (0, b). The y value of the y intercept point is denoted by the symbol b in the formula.

Given:

From the parabolic graph we can see that the intersecting point (0, 8)

What is Unitary Method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

For cotton:

5.54 ÷ 3/4

=7.39<8

For flannel:

2.62 ÷ 3/4

=3.49<8

For fleece:

4.27 ÷ 3/4

=5.69 < 8

For terry cloth:

=6.52 ÷ 3/4

= 8.69>8

So, cost less than $8 per yard cotton, flannel and fleece.

Quadrilateral WXYZ is a square. If WT=6, find each measure?

Answers

We know that the diagonals of a square bisect each other which results in the formation of 4 - 90° angles . Which means ZX = 2 × WT . Then ,

= ZX = 2 × 6

= ZX = 12 ( ZX is a diagonal )

Side XY =

XY = √2 d/2

XY = √2 . 12/2

XY = 8.48528

m∠WTZ = 90° ( as the diagonals of a square intersect to form a complete angle ( 360° ) which is divided into four equal parts , each part being 90° )

m∠WTZ = 90°

m∠WYX = 45° ( WYX is half of one of the interior angles in this square which will mean it will be equal to 45° )

Therefore , m∠WYX = 45°

In short :

ZX = 12

XY = 8.48528

m∠WTZ = 90°

m∠WYX = 45°
