Answer:

Step-by-step explanation:

To get from the top square to the bottom square, multiply by - 3 So the middle position of the bottom square is - 30. If you solve all of the top square, you can get the bottom square easily enough.

The diagonal of the top square adds to 13 + 10 + 7 = 30

The top line of the top square must add to 30 as well 13 + 11 + 6. Put 6 in the middle position.

The right hand vertical line must add to 30. 11 + 7 + 12 = 30

The middle row must add to 30. 10 + 12 + 8. 8 goes in the left position of the middle row.

Let's summarize what we have so far.

13 6 11

8 10 12

We can fill in the last two spaces by adding to 30

13 6 11

8 10 12

9 14 7

That completes the top magic square.

To get the bottom magic square, multiply by -3

- 39 - 18 -33

-24 -30 -36

-27 -42 -21

Need help with #5.<br> Find angle and solve for x

Leona [35]

Answer:

see explanation

Step-by-step explanation:

The 2 marked angles are vertical and congruent, thus

24x = 23x + 5 ( subtract 23x from both sides )

x = 5

Thus angles = 24 × 5 = 120°

Keith is a drummer who purchases his drumsticks online. When practicing with the newest pair, he notices they feel heavier than

Marina86 [1]

Answer: 0.0174

Step-by-step explanation:

Given : $\mu=1.85\ \ ; \sigma=0.18$

Let x be the random variable that represents the weight of the drumsticks.

We assume that the weight of the drumsticks is normally distributed.

Now, the z-score for x=2.23 , $\because z=\dfrac{x-\mu}{\sigma}$

$\Rightarrow\ z=\dfrac{2.23-1.85}{0.18}\approx2.11\ \ \$

Using z-value table , we have

P-value =P(x≥2.23)=P(z≥2.11)=1-P(z<2.11)=1-0.9825708

=0.0174292≈0.0174 [Rounded nearest 4 decimal places]

Hence, the probability of the stick's weight being 2.23 oz or greater = 0.0174
