Plug in 3 for x and 30 for y
5(3 + 8) + 3 + 30
Use PEMDAS
5(11) + 3 + 30
55 + 33
88
88 is your answer
hope this helps
Answer:
A it is linear because it has a constant rate of change
Answer:
The 95% confidence interval is "87.94, 91.86".
Step-by-step explanation:
The given values are:
Sample batches,
n = 25
Sample mean concentration,
= 89.9 mg
Amount of chemical,
σ = 5
α = 0.05
The critical value from Z table will be:
=
=
=
Now,
The confidence interval will be:
=
On substituting the values, we get
=
=
=
Lower limit will be:
=
=
Upper limit will be:
=
=
Answer:
2
Step-by-step explanation:
Given
7x + 2 = 16
Subtracting 2 from both sides
7x + 2 - 2 = 16 - 2
7x = 14
Dividing both sides by 7
7x / 7 = 14 /7
x = 2
Hope it will help :)
Answer: All of the answers are correct.
Step-by-step explanation:
A probability distribution is the collection of probabilities which defines the likelihood of observing all the various outcomes of an experiment or event. A probability distribution has two main properties which are that:
• Each probability in the distribution consist of a value between 0 and 1.
• The sum of all probabilities in the distribution equals 1.
Also, in probability, an outcome is the possible result of an experiment and each possible outcome gotten is unique, therefore the different outcomes are mutually exclusive i.e. only one outcome can occur on each trial during the experiment.
