If we drew a line of best fit, the gradient would be roughly equal to 1, and the y intercept would be at around -4
Answer:
98%
Step-by-step explanation:
If the probability of winning a school raffle is 2%, the probability of not winning the raffle would be 98%.
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

Answer:
a. 2
Step-by-step explanation:
The given function is
.
We can see from the graph that the graph has two x-intercepts.
This means that the function has two real zeros.
By the fundamental theorem of Algebra, the function is supposed have four roots since it is a polynomial of degree 4.
Therefore, the other two zeros are complex.
See graph
First, you need to find the slope of HI.
Find two points. (On the line)
(-5,5) (1,9) I’m just going to use the points for H and I.
Plug it into the slope formula.
M= (y2-y1)/(x2-x1)
M= (9-5)/(1-(-5) Switch the sign to be positive, two negatives equal a positive.
M= 4/6
Now, you just need to find the opposite reciprocal for the slope of the perpendicular line.
Flip 4 and 6. Make it negative.
-6/4
Simplify.
-3/2 or -1.5
I hope this helps!
