Answer:
the graph is attached
Step-by-step explanation:
This sort of equation makes it easy to find the x- and y-intercepts. Setting x to zero gives ...
y = -11 . . . . . the y-intercept
Setting y to zero gives ...
x = -11 . . . . . the x-intercept
You can plot these two points, then draw a line through them to complete the graph.
Every point on this line is a solution to the equation.
50 girls attended the trip.
80 boy + 50 girls = 130 total students
8x10 =80
5x10=50
multiply both by 10.
Answer:
Step-by-step explanation:
Given that there are 20 non ionized containers and 73 ionized containers
Two samples are drawn without replacement
a) the probability that the first one selected is not ionized=
b) the probability that the second one selected is not ionized given that the first one was ionized
= When first one was ionized we got left over as 20 and 72
Hence = 
c) If with replacement left over 20 and 73 and hence prob = 0.215 as in part a
d) the probability that both are ionized=
