Answer:
75 in³
x: 30
y: 20 35
Step-by-step explanation:
v = πr²h / 3
v = 3.14 * 3² * 8 / 3
v = 3.14 * 9 * 8 / 3
v = 75.36 in³
Rounded
v = 75 in³
---------------------
x increase by 10 for each step
y increases by 7.5 for each step
x: 0 10 20 30 40
y: 5 12.5 20 27.5 35
I might be wrong-
The commutative property holds for subtraction only.<span>When the numbers being subtracted are the same. It is sometimes true.</span><span>
Sorry if I'm wrong. </span>
With replacement, probability of selecting a good bulb remains
(63-9)/63
=6/7
If the bulbs are selected WITH replacement three times, then
P(all good)
= (6/7)^3 (by the multiplication rule)
= 216/343
= 0.630 (to three decimal places)
Answer:
1/52
Step-by-step explanation:
To obtain the probability of drawing a 9 of spade from a deck of 52 cards ;
Probability = (number of required outcomes / number of total possible outcomes)
Number of Required outcomes = 1 (there is only one 9 of spade in a deck of 52 cards)
Hence,
P(9 of spade). = 1 / 52
(3,51)(5,59)
slope = (59 - 51) / (5 - 3) = 8/2 = 4
y = mx + b
slope(m) = 4
(3,51)...x = 3 and y = 51
sub and find b, the y int
51 = 4(3) + b
51 = 12 + b
51 - 12 = b
39 = b
so ur equation is : y = 4x + 39...but u need it in standard form
y = 4x + 39
-4x + y = 39
4x - y = -39 <==== this is ur equation...x = number of hrs and y = total velocity
====================
ur x axis is the number of hrs
ur y axis is total velocity in km
y = 4x + 39......slope = 4.....y int = (0,39)....x int is (- 9.75,0) or -9 3/4 for graphing purposes)....so start at (-9.75,0)...and since the slope is 4, go up 4 and to the right 1....plot that...then up 4 and to the right 1...plot that...u will cross the y axis at (0,39)....and just connect ur plotted points and u have ur line......or what u can do since it is asking for the first 6 hrs....sub in 1 for x and solve for y....then sub in 2 for x and solve for y...keep doing this up till 6 and u will have ur line up till 6 hrs
