Answer:

[tex]t^2=9.2[/tex]

Step-by-step explanation:

From the question we are told that

Standard Deviation [tex]\sigma=28.8[/tex]

Sample space [tex]n=12[/tex]

[tex]s^2= 21.6[/tex]

Generally the equation for test statistics is mathematically given by

[tex]t^2=frac{(n-1)*s^2}{\sigma^2}}[/tex]

[tex]t^2=\frac{(12-1)*21.6}{25.8}[/tex]

Therefore the standardized test statistics

[tex]t^2=9.2[/tex]

Step-by-step explanation:

note that [tex]\sqrt{-1}[/tex] = i

[tex]\sqrt{64-112}[/tex]

= [tex]\sqrt{-48}[/tex]

= [tex]\sqrt{16(3)(-1)}[/tex]

= [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] × [tex]\sqrt{-1}[/tex]

= 4 × [tex]\sqrt{3}[/tex] × i

Answer:

Step-by-step explanation:

The difference is 7-5 = 2 "ratio units", corresponding to a difference of 36 dancers. Then each "ratio unit" stands for 36/2 = 18 dancers.

There are 7×18 = 126 girls.

There are 5×18 = 90 boys.

_____

You could solve this by writing some equations:

  g/b = 7/5

  g -b = 36

Then you could substitute for g:

  (36+b)/b = 7/5

  36/b +1 = 2/5 +1 . . . . expand the fractions

  36/b = 2/5 . . . . . . . . . subtract 1

  b = (5/2)(36) = 90 . . . multiply by 5/2b

  g = 36+90 = 126

Answer:

The area of a parallelogram is: 96 cm²

Step-by-step explanation:

Given

To determine

The area of a parallelogram A = ?

Using the formula to calculate the area of a parallelogram

A = bh

here

so substituting b = 12 and h = 8 in the equation

A = bh

A = 12×8

A = 96 cm²

Therefore, the area of a parallelogram is: 96 cm²

Answer:

3.86242560*10^8

Step-by-step explanation:

Scientific notation is in the form a*10^b

where b is an integer. And 1 <= a < 10

The average distance of the moon from earth represent as; 3.86242560 x 10^8 scientific notation.

The number is written in the form [tex]a \times 10^b[/tex] where we have[tex]1 \leq a < 10[/tex]

where b is an integer which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. For an instant, we can ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

We have been given that the average distance of the moon from earth is 386,242,560 m.

We know that the scientific notation is in the form [tex]a \times 10^b[/tex]

It can be written as;

38624256 × 10

Or

3.86242560 x 10^8

Answer:

B

Step-by-step explanation:

The linear equation is written in slope-intercept form [ y = mx + b ]. Where m = slope and b = y-intercept. With the equation give, we know that m = 5 and y = 9. A point is written as (x, y) and we are given the y-intercept 9 so the only logical answer is B.

Answer:

when x = -1,  y = -3

when x = -1,  y = -1

when x = -1,  y = 1

when x = -1,  y = 3

Step-by-step explanation:

x = -1;  plug in y = 2(-1) - 1 = -2 - 1 = -3

x = 0;  plug in y = 2(0) - 1 = 0 - 1 = -1

x = 1;  plug in y = 2(1) - 1 = 2 - 1 = 1

x = 2;  plug in y = 2(2) - 1 = 4 - 1 = 3

Answer: B

The value of the variable h is greater than 75.5 that means at 75.5 there will be an open circle.

A number line refers to a straight line in mathematics that has numbers arranged at regular intervals or portions along its width. A number line is often shown horizontally and can be postponed in any direction.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given below.

h > 75.5

The value of the variable h is greater than 75.5 that means at 75.5 there will be an open circle.

Answer:

We have;

7 pencil boxes and 5 eraser boxes

Step-by-step explanation:

To find the smallest number of boxes that can be bought, what we simply do is to find the lowest common multiple of the content of each of the boxes

hence, we are going to find the lowest common multiple of 10 and 14

The lowest common multiple of 10 and 14 is 70

So the smallest number of pencil boxes that can be bought is 70/10 = 7

The smallest number of eraser boxes would be 70/14 = 5
