Answer:
Step-by-step explanation:
y = (-1/2)x + 4 is the equation of a straight line with y-intercept (0, 4) and slope -1/2.
To graph this, first plot the y-intercept (0, 4).
Recall that slope m = rise / run, and notice that the slope in this particular case is -1/2 = rise / run, or rise = -1 and run = 2.
Starting with your pencil point on (0, 4), move the point 2 units to the right (run = 2), arriving at (2, 4). Next, move your pencil point 1 unit down, to (2, 3).
Draw a straight line through (0, 4) and (2, 3).
Answer:
a) 0.0184
b) 0.1829
Step-by-step explanation:
a) With geometric distribution you can measure the number of trials until the first success, that is, a defective chip is found, as follows:
P(x = k) = p*(1-p)^(k-1)
This means: probability to find exactly 1 defective in k trials, p is the probability to find a defective chip, which is equal to 0.02, and the number of trials are k = 5. Replacing:
P(x = 5) = 0.02*(1-0.02)^(5-1) = 0.0184
b) If you want the probability of 1 success within k trials, compute:

Replacing with k = 10

Let z=x+iy be a complex number. The distance from this complex number to the origin is

Consider all options:
A. z=2+15i, then 
B. z=17+i, then 
C. z=20-3i, then 
D. z=4-i, then 
Answer: correct choice is D.
1/3 divided by 1/4= 4/3
The method for dividing fractions is keep change flip.
Keep the 1/3, change the division sign to multiplication sign, flip the 1/4 to a 4/1, then solve.
.75 pounds in each bag. If you add the total pounds of meat in the 2 packages, 4.5+2.25 you get 6.75. if you divide all 6.75 pounds equally into 9 bags, 6.75/9, you would get a total of .75 or 3/4 of a pound in each bag.
