Answer:

Tanner's score = 70

Step-by-step explanation:

Data provided in the question:

Mean value of the statistics test taken by Tanner = 80

Standard deviation = 5

Total points possible = 100

Now,

It is given that the Tanner's score was 2 standard deviation below the mean

Mathematically,

Tanner's score = Mean - ( 2 × Standard deviation )

or

Tanner's score = 80 - ( 2 × 5 )

or

Tanner's score = 80 - 10

or

Tanner's score = 70

Why does the multiplication property of equality not allow us to divide both sides of an equation by zero?​
Anna71 [15]

First of all, recall that division by zero is undefined; it's nonsensical; it's just not allowed.So zero certainly needs to be excluded when dividing.

But what about multiplying by zero?

The problem is that multiplying by zero can change the truth of an equation:

It can take a false equation to a true equation.

To see this, consider the false equation ‘

2 = 3

Multiplying both sides by zero results in the new equation

2 ⋅ 0 = 3 ⋅0 (that is, ‘0 = 0’), which is true.

12(4x−5)+5/2=10 solve for x pls help!!!!
True [87]

Answer:

Step-by-step explanation:

12(4x - 5) + \frac{5}{2}=10

Multiply the whole equation by 2

2*12(4x -5) + \frac{5}{2}*2=10*2\\\\24(4x-5) + 2 = 20\\

24*4x - 5*24 + 2 = 20

96x - 120 + 2 = 20

 96x - 118 = 20

Add 118 to both sides

       96x = 20 +118

       96x = 138

Divide both sides by 96

x = 138/96  = 23/16

x = 1 \frac{7}{16}

Complete the data set with one value so that the mean of the data is 13.
Grace [21]

Answer:

14

Step-by-step explanation:

(10 + 14 + 8 + 16 + 12 + x ) /6 = 13

(60 + x) / 6 = 13

60 + x = 13 * 6

60 + x = 78

x = 78 - 60

x = 18

(10+14+16+12+18)/5

= 70/5 = 14

Hope this helps, good luck!
