You don't even have to look up the definition of 'standard deviation'.  You only
have to remember that 'smaller standard deviation' means 'less spread-out'.

First, let's find the mean (average).  It's not supposed to change:

1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .

Now, just pick 7 scores that total 561 and are all bunched up.

The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.

Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .

Which of the following points is in the solution set of y &lt; x2 - 2x - 8?
777dan777 [17]

The solution set of the given inequality has a domain of (-∞, ∞) and the vertex(h,k) = (1, -9)

<h3>What is the solution set for inequality?</h3>

The solution set for inequality is the set of all solutions for which the inequality is defined. It can also be represented in an interval notation.

Given that:

  • y < x² - 2x - 8

By rewriting the equation in the parabola standard form 4p(y-k) = (x - h)², we have:

\mathbf{4\times \dfrac{1}{4}(y-(-9)) = (x-1)^2}

Therefore, the parabola properties are:

  • The solution set of the domain is (-∞, ∞)
  • Vertex(h,k) = (1, -9)
  • Focal length |p| = 1/4

kotykmax [81]

Answer:

5 groups

2 extra children

Step-by-step explanation:

The computation of a number of groups and number of extra children is shown below:

Given that

There is 27 children

And, this group would be divided into group 5

So,

As we know that 25 is easily divided by 5

So there are 5 groups

And, the extra children is

= 27 - 25

= 2 chidren

Firdavs [7]

Answer:

5 35/72 kilometers

Step-by-step explanation:

The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode

This is calculated as:

Total distance = 6 7/12 km

Evan rode = 5/6 of the distance

Hence:

The distance Evans rode is

5/6 of 6 7/12

= 5/6 × 79/12

= 395/72

= 5 35/72 km(kilometers)
