Answer:
20% probability of a red
Step-by-step explanation:
How many marbles are there total?
12 + 10 + 6 + 10 + 22 = 28 + 32 = 60 marbles
P(red marble) = 12 red/ 60 total marbles = 12/60 = 1/5 = 20%
Answer:
(0, 3 )
Step-by-step explanation:
To find the y- intercept , substitute x = 0 into f(x), that is
f(0) = 3 ×
[ note
= 1 ]
= 3 × 1
= 3
y- intercept = (0, 3 )
To find the X intercept, replace y with 0 and solve for x:
9x + 21(0) = 16
9x = 16
x = 16/9
To find the Y intercept, replace x with 0 and solve for y:
9(0) + 21y = 16
21y = 16
y = 16/21
X-intercept is 16/9
y intercept is 16/21
OK: slope is rise/run so 6-1/0--1=5/1
So, 5/1 or 5 is your slope
Answer:
3,272
Step-by-step explanation:
8 x 400 = 3200
8 x 9= 72
3200 + 72 = 3,272
