Correct answers are A, C and D.
Parallel lines have equal slopes.
4x - y = -5 ⇒ y = 4x + 5 ⇒ m = 4
8x - 2y = -10 ⇒ 4x - y = -5 ⇒ m = 4
4x + y = -2 ⇒ y = -4x - 2 ⇒ m = -4
4x - y = 2 ⇒ y = 4x - 2 ⇒ m = 4
The formula for a binomial probability function is the one that is attached to the image.
Where:
n = number of trials.
x = number of successes from which you want to know the probability.
p = probability of obtaining success.
In this case, success is defined as obtaining a result of type a.
We look for the probability of obtaining 4 results of type a.
So:
n = 10.
x = 4.
p = 0.70.
In this way:
P (x = 4) = 0.0368. If we now look for the probability of obtaining 5 results of type b.
So:
n = 10.
x = 5.
p = 0.20.
P (x = 5) = 0.0264.
Finally, the probability of obtaining 1 result of type c.
n = 10.
x = 1.
p = 0.1.
P (x = 1) = 0.387. Finally, the probability of obtaining 4 results of type a, 5 of type b and 1 of type c is:
P (4a + 5b + 1c) = 0.0368 * 0.0264 * 0.387.
P = 0.0376%
in this one x=9 ask if you need an explanation
$50 corresponds to 4 kg
That means there must be a number that when you multiply by 4 you get 50.
Let that number be k. k is the price of cheese per kg.
1 kg: y = k * 1
2 kg: y = k * 2
Answer:
the number 
is three million times larger than 
Step-by-step explanation:
To answer this, just do the quotient of the first one over the second one, and use the rules for quotient of exponential expressions of the same base:
So the answer is: the number is three million times larger than
