garri49 [273]2 years ago
7 0

Answer:  3

Explanation:

She wants to get 70%, so we need to solve

x/20 = 70/100

Doing so gets us

100x = 20*70

100x = 1400

x = 1400/100

x = 14

She needs to have 14 questions correct, out of 20, to get a score of 70%

14/20 = 0.70 = 70%

She needs to get 14-11 = 3 more correct questions.

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> .

strojnjashka [21]
Since she has $6 off for all the pizzas, she can get 10 pizzas with a $6 discount.
She would save $6 since, she has the discount and she would still have something left so she could buy something more if she wished to.
