Solution :

Given :

National mean score of the reading test that is conducted the NAEP = 288

Standard deviation of the score = 38

Therefore, P(X > x) = 0.25

P (Z > [tex]$\frac{x-288}{38} $[/tex] = 0.674)

[tex]$\frac{x-288}{38} = 0.674$[/tex]

[tex]$x=288+(38 \times 0.674)$[/tex]

x = 326.67

Therefore, the highest score that is needed for the students to be in the top of 25 percent among the students those who take the exam.

Answer:

130 in^2 net area

136 in^2 gross area (counting the 6 in^2 scrap loss for the side cutouts)

Step-by-step explanation:

top=1.5x4=6

middle=1.5x4=6

bottom=3x4=12

sides=(2x3x8)-(2x1.5x2)=42

front & back=2x8x4=64

6+6+12+42+64=130

The amount of cardboard required to make one box is 130 inch².

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

From the figure we have

top = 1.5 x 4 = 6

and, middle = 1.5 x 4 =6

and, bottom = 3 x 4 = 12

So, the side is

= (2 x 3 x 8) - (2 x 1.5 x 2)

=42

and, For front and back

= 2 x 8 x 4

=64

Thus, the amount cardboard required

= 6+6+12+42+64

= 130 in²

Answer:

Step-by-step explanation:

From the information given:

We can compute the required calculations into a table as shown below.

[tex]\mathbf{Data \ value }[/tex]       [tex]\mathbf{ Frequency }[/tex] [tex]\mathbf{Relative \ frequency}[/tex]   [tex]\mathbf{Cumulative \ relative }[/tex]

                                                                                              [tex]\mathbf{Frequency}[/tex]

5                                     14                14/65 = 0.22                           14  

6                                     19                19/65 = 0.29               19+14 = 33

7                                      12                12/65 = 0.19               33+12 = 45

8                                       9                 9/65 = 0.14               45 + 9 = 54

9                                     11                11/65  = 0.17              54 + 11 = 65

                                        65

Note: that the relative frequency is determined by  dividing each value in the frequency by the total of the frequency.

Answer:

C  89a + 2c)

Step-by-step explanation:

The largest factor of both 8 and 16 is 8.  So, 8 = GCF

factor out an 8 and you get 8(a + 2c)

To check if you are correct, multiply and see if you get what you started with.

Answer

Step-by-step explanation:   your answer would be -42  so heres how i did it: Evaluate for a=−5,c=−1

(8)(−5)+(2)(−1)

(8)(−5)+(2)(−1)

=−42

Answer:

it is multiplying by 2 every time. so it would be x(2)

x would be the numbers like -2....etc

hope this is what you were asking!!

its times 2 each time so -2×2=-4 and so on and so on

Answer:

Since, Y = x + 2

so, 5x-7y = 58

5x-7×x+2 = 58

5x-7x = 58

-2x = 58

x = 58÷2

x = 29

The loss percentage is 20%.

We have the following information available from the question is:

Saggar sold a watch at Rs.400 that he had purchased at Rs.500.

We have to find the Percentage loss.

Now, According to the question:

Cost price of watch is (CP): $500

Selling price of watch is (SP): $400

Loss percentage= Loss/CP x 100.

Loss = C.P. - S.P.

Loss = 500 - 400

Loss = $100

Plug all the values in the formula of loss percentage.

Loss percentage = 100/500 x 100

Loss Percentage is 20%

Answer: 2*L - 5 = 11

Step-by-step explanation:

Suppose that we have a rectangle with length L and width W.

Now we know that:

" 5 less than twice the length equals 11"

Then we get:

"twice the length" is written as 2*L

5 less than that is:

2*L - 5

And this is equal to 11, then:

2*L - 5 = 11

This is the algebraic equation we wanted to find,

Answer:

Step-by-step explanation:

Compare coordinates of S and M

difference in x-coordinates = 4-6 = -2

difference in y-coordinates = 2-1 = 1

x-coordinate of R = x-coordinate of M - 2 = 4-2 = 2

y-coordinate of R = y-coordinate of M + 1 = 3

Step(i):-

Given that the line y =f(x) = 2x +6

                           ⇒  y = 2x +6

 comparing             y =mx +c

The slope of the given line   m =2

Step(ii):-

The slope of the perpendicular line   = [tex]\frac{-1}{m}[/tex]

Answer:

What do you need though...

A basic rundown since I have no clue what you need help with

Parallelograms

(4 sided shapes that always adds up to 360 degrees if you add all the angles inside with opposite sides parallel)

Squares, rectangles (most common)

Triangles

3 sided figures with all the interior angles being added up equals to 180 degrees. The 3 sides of a triangle can be found with a^2+b^2=c^2.

The properties are 2 legs and 1 hypotenuse. To determine if its a triangle, if the 2 legs added up (two of the shortest sides) they must be greater then the hypotnuse (greatest side).

THese are the two of the most common shapes if you need an huything else just lemme know in the comments.

Step-by-step explanation:

we make 7 * 8 = 56

we retain 5

after 7 * 6 = 42 + 5 = 47

below 6 we put a 0 then after we do 1 * 8 = 8 and 1 * 6 = 6 and finally we all calculate so 476 + 680 = 1156

Given:

The data values are

11, 12, 10, 7, 9, 18

To find:

The median, lowest value, greatest value, lower quartile, upper quartile, interquartile range.

Solution:

We have,

11, 12, 10, 7, 9, 18

Arrange the data values in ascending order.

7, 9, 10, 11, 12, 18

Divide the data in two equal parts.

(7, 9, 10), (11, 12, 18)

Divide each parenthesis in 2 equal parts.

(7), 9, (10), (11), 12, (18)

Now,

Median = [tex]\dfrac{10+11}{2}[/tex]

            = [tex]\dfrac{21}{2}[/tex]

            = [tex]10.5[/tex]

Lowest value = 7

Greatest value = 18

Lower quartile = 9

Upper quartile = 12

Interquartile range (IQR) = Upper quartile - Lower quartile

                                        = 12 - 9

                                        = 3

Therefore, median is 10.5, lowest value is 7, greatest value is 18, lower quartile 9, upper quartile 12 and interquartile range is 3.

The simplification of the given expression using laws of exponents is: 80x⁸

Some of the laws of exponents are:

- When multiplying by like bases, keep the same bases and add exponents.

- When raising a base to a power of another, keep the same base and multiply by the exponent.

- If dividing by equal bases, keep the same base and subtract the denominator exponent from the numerator exponent.  

The expression we want to solve is given as:

4x²√(5x⁴) * 3√(5x⁸)

Using the concept of laws of exponents, this simplifies as:

4x² * x² * 3x⁴ * 5

= 80x⁸
