Answer: 1260 books
Step-by-step explanation:
2/5=0.4
19000x0.4=7600
12500x0.4=5000
7600+5000=12600
1/10=0.1
12600x0.1 = 1260
Answer:
Experiment, but not completely randomized experiment.
Step-by-step explanation:
An experimental design typically shows the layout of the planned experiment and this also facilitates the understanding of the experiment at glance. It is also pertinent to understand that, it is crucial to apply a suitable design regarding the need of the experiment. So, according to what the farmer conducted, he carried out an experiment but not a completely randomized experiment.
Answer:
Mean = 16.5
Variance = 35.55
Step-by-step explanation:
<u> x P(x) x. P(x) x² x². P(x)</u>
6 0.10 0.6 36 3.6
12 0.35 4.2 144 50.4
18 0.25 4.5 324 81
<u> 24 0.30 7.2 576 172.8</u>
∑x P (x) 16.5 ∑x² P (x) 307.8
The expected value of x E[X] gives the mean where X is the discrete random variable with the given probabilities.
Mean is given by E(X)= ∑x P (x) = 16.5
Similarly the variance is also calculated using the expected value of X and X².
Variance is given= E(X)²- [E(X)]²= 307.8- (16.5)²= 307.8-272.25 = 35.55
Answer:
w = 5 inches
l = 11 inches
Step-by-step explanation:
The formula for exponential growth is:
Total = starting value x (1 + rate)^ time
Using the information in the problem the formula would be:
y = 2300(1.093)^t
