False if it is congruent it should be written in order
-3x + 2y = 4
2y = 3x + 4
y = 3/2x + 2
so ur slope is 3/2 and ur y int is (0,2)
ur x int can be found by subbing in 0 for y and solving for x
-3x + 2(0) = 4
-3x = 4
x = -4/3...so ur x int is (-4/3,0)
so plot ur x and y intercepts (0,2) and (-4/3,0)....and start at (-4/3,0) and since ur slope is 2, go up 2 spaces and to the right 1 space, then up 2 spaces, and to the right 1 space...keep doing this and u should cross the y axis at (0,2)
Answer:
a) 1/10
b) 110
Step-by-step explanation:
A) we start by getting the total number of rolls
That would be;
11 + 22 + 7 + 8 + 13 + 19 = 80
The frequency of getting a 4 is 8
The probability that the next roll will be a 4 is;
8/80 = 1/10
b) Firstly, we get the probability of getting a 2
We have this as:
22/80
So for 400 rolls, the number of 2’s will be;
22/80 * 400
= 22 * 5 = 110
