Answer:

B.30

Step-by-step explanation:

The difference is subtracting so we have

y-x=-8

We know one is 22 so we replace y with 22:

22-x=-8

Now all we need to do is solve:

Subtract 22 on both sides:

-22+22-x=-8-22

-x=-30

Divide by - or -1 on both sides:

-x/-1=-30/-1

x=30

So the "number" is 30

Hope this helps!

Find the 20th, 40th, 60th, and 80th percentiles of the standard normal distribution. Round the answers to two decimal places.

Fed [463]

To answer the question above, we have to use the z-score percentile table for the standard normal distribution. It shows:
The 20th percentile = - 0.84
The 40th percentile = - 0.25
The 60th percentile = 0.25
The 80th percentile = 0.84

I hope my answer helped you. Have a nice day!

5x-4y=19<br> x+2y=8<br> solve the simaltaneous equation

STatiana [176]

Answer:

( 5, 3/2 )

x = 5

y = 3/2

Step-by-step explanation:

5x - 4y = 19

x + 2y = 8

-------------------

2(x + 2y = 8) = 2x + 4y = 16

----------------------

5x - 4y = 19

2x + 4y = 16

7x = 35

÷7 ÷7

x = 5

-----------------------

x + 2y = 8

5 + 2y = 8

-5 -5

2y = 3

÷2 ÷2

y = ( 3/2 )

I hope this helps!

Using the digits 0 to 9

Gre4nikov [31]

Supplementary Angles:

$\boxed{100°} and \boxed{80°}$

Arithmetically speaking, the closest 2 supplementary angles can get (in 3 and 2 digits respectively) is the upwritten.

Complementary Angles:

$\boxed{45°} and \boxed{45°}$

Simply, in this case, for angles to be numerically as close as possible - make both the angles 45°.
