Examine Kaitlyn’s steps for solving the system of equations. –3x + 2y = 8
3x + 2y = –6

Step 1: 4y = 2

Step 2: y = 2

Step 3: –3x + 2(2) = 8

Step 4: –3x = 4

Step 5: x = –1.333

Kaitlyn found the solution to be (1.3, 2). Is her solution correct? Explain.

Yes, she correctly solved the system of equations.
No, she made an error in step 1. The y variable should have been eliminated when adding the system of equations.
No, she made an error in step 2. She should have found y = 0.5.
No, she substituted y into the wrong equation to solve for x in step 3.

option 3, she made a mistake in step 2. y=1/2 or .5

Its C :)

i did it on edge unity so trust me lol

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
