Answer:

The probability is 0.02275

Step-by-step explanation:

We shall first find the z-score here

z-score = (x -mean)/SD

from the question;

x = 4,000

mean = 3,000

SD = 500

z-score = (4,000-3,000)/500 = 1000/500 = 2

So the probability we want to calculate is;

P(z > 2) = 0.02275

Solve for p.
Marat540 [252]
Hi there

3(p + q) = q
Solve for P

Use the distributive property
(3)(p) + (3)(q) = q
3p + 3q = q
3p = q-3q
3p = -2q
p = -2q/3

The answer is D

If you have any further questions please let me know :)

Use the Pythagorean Theorem: .

So your straight line distance is 10.

We can also recognize this as a multiple of the 3-4-5 Pythagorean triple. We have , with x being the desired value. Therefore x=10, like previously.

X+8=-2<br><br> O A. x= 10<br> OB. x=-6<br> O C. x=6<br> OD. x= -10
MaRussiya [10]

Answer: option D

Step-by-step explanation:

X+8=-2

    x= -2-8 (you should make x the subject so you switch the +8 to the other

    x= -10                                                                   side which becomes -8)    

so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D
