1. 28 x 3/4 = 21 kg
2. 1 hr = 60 mins
=》 1/4 hr = 60/4 = 15mins
6 total beads
1 is yellow
1 is blue
1/6 of getting a yellow
1/6 of getting a blue and
1/6 of getting a yellow again
1/6 * 1/6 * 1/6 = 1/216 probability
A.
Multiply the number of days, x by 50 per day to get 50x.
Next multiply the number of miles driven to the amount she gets per mile: 0.60 x 200 = $120
Now add both together to equal the total of 1620.
The equation becomes: 50x +120 = 1620
B.
50x +120 = 1620
Step 1: subtract 120 from both sides ( subtraction property of equality):
50x = 1500
Step 2: Divide both sides by 50 ( division property of equality):
x = 1500 / 50
x = 30
C.
The trip lasted 30 days.
(5/6,39),(5/8,29.85)
slope = (29.85 - 39) / (5/8 - 5/6) = - 9.15 / (-5/24) = -9.15 * - 24/5 =
219.6 /5 = 43.92
y = mx + b
slope(m) = 43.92
(5/6,39)....x = 5/6 and y = 39
now sub and find b, the y int
39 = 43.92(5/6) + b
39 = 36.6 + b
39 - 36.6 = b
2.4 = b
so ur equation would be : y = 43.92x + 2.4
and when it is empty, x = 0
y = 43.92(0) + 2.4
y = 2.4 <=== so when the tank is empty, the mass is 2.4 kg
Answer:
Mean = 3.4
Variance = 1.088
Standard deviation = 1.0431
Step-by-step explanation:
The mean of a binomial distribution with parameters N (the number of trials) and p (the probability of success for each trial) is 
Thus,
The variance of the binomial distribution is 
, where 
is the variance of the binomial distribution, so
The standard deviation 
is the square root of the variance 
so
