Consider a value to be significantly low if its z score less than or equal to minus 2 or consider a value to be significantly hi

Readme [11.4K]

Answer:

The scores that are less than or equal to 10.8 are considered significantly low.

The scores that are greater than or equal to 32.4 are considered significantly high.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 21.6

Standard Deviation, σ = 5.4

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

Significantly low score:

$z \leq -2\\z = \displaystyle\frac{x-21.6}{5.4} \leq -2\\\\\displaystyle\frac{x-21.6}{5.4} \leq -2\\\\x\leq -2(5.4) + 21.6\\\Rightarrow x \leq 10.8$

Thus, scores that are less than or equal to 10.8 are considered significantly low.

Significantly high score:

$z \geq 2\\z = \displaystyle\frac{x-21.6}{5.4} \geq 2\\\\\displaystyle\frac{x-21.6}{5.4} \geq 2\\\\x\geq 2(5.4) + 21.6\\\Rightarrow x \geq 32.4$

Thus, scores that are greater than or equal to 32.4 are considered significantly high.

Hypotenuse: The ________ side of a right triangle; side ________ from the right angle.

Stels [109]

The Hypotenuse is the Longest side of right triangle; side Opposite from the right angle.

According to the statement

we have given that the property of the hypotenuse of the triangle and we have to complete it.

So, For this purpose, we know that the

A hypotenuse is the longest side of a right-angled triangle, and The length of the hypotenuse can be found using the Pythagorean theorem.

Now we discuss about the properties of the hypotenuse;

The hypotenuse is the longest side in a right angled triangle.
The hypotenuse is opposite the right angle.
The midpoint of the hypotenuse is the circumference.

And from these properties we have to complete the given property.

So, The Hypotenuse is the Longest side of right triangle; side Opposite from the right angle.

Sharkira went bowling with her friends.She paid $3 to rent shoes and then 4.75 for each game of bowling. If she spent a total of

9966 [12]

$21 - $3 = $18

$18 - $4.75 = $13.25

$13.25 - $4.75 = $8.50

$8.50 - $4.75 = $3.75

Which means that she played 3 games, and has $3.75 left over.

But if you were to divide 4.75 from 21 it would equal 4 games and $2 left over.

21 - 4.75 = 16. 25

16.25 - 4.75 = 11.50

11.50 - 4.75 = 6.75

6.75 - 4.75 = 2

4 games and $2 dollars left over.

Evaluate 7+q(r−8)2 when q = 3 and r = 10.

liberstina [14]

Answer:

The solution of the expression is 19.

Step-by-step explanation:

Given:

q = 3
r = 10

Work:

=> 7 + q(r − 8)2
=> 7 + 3(10 - 8)2
=> 7 + 6(10 - 8)
=> 7 + 6(2)
=> 7 + 12
=> 19

Hence, the solution of the expression is 19.

Hoped this helped.
