The random variable R has the binomial distribution B (12,0.35) .find P(R>4)
Answer: [tex]0.416655[/tex]
Step-by-step explanation:
If random variable X has the binomial distribution B(n, p), then
[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]
, where n= Total number of trials, x = number of successes , p= probability of success in each trial.
Given: The random variable R has the binomial distribution B (12,0.35).
n= 12, = 0.35
[tex]P(R>4)=1-P(R\leq4)\\\\=1-[P(R=0)+P(R=1)+P(R=3)+P(R=4)]\\\\\\=1-[^{12}C_0(0.35)^{0}(1-0.35)^{12}+^{12}C_1(0.35)^{1}(1-0.35)^{11}+^{12}C_2(0.35)^{2}(1-0.35)^{10}+^{12}C_3(0.35)^{3}(1-0.35)^{9}+^{12}C_4(0.35)^{4}(1-0.35)^{8}]\\\\= 1-[(1)(0.65)^{12}+(12)(0.35)(0.65)^{11}+\dfrac{12!}{2!10!}(0.35)^2(0.65)^{10}+\dfrac{12!}{9!3!}(0.35)^3(0.65)^{9}+\dfrac{12!}{8!4!}(0.35)^4(0.65)^{8}]\\\\=1-0.583345\\\\\approx0.416655[/tex]
Hence, P(R>4)=0.416655
solve for c.
c - 7 = -9
Answer:
[tex]c = 2[/tex]
Step-by-step explanation:
In order to find the answer to this question you must add 7 on both sides.
[tex]c-7=-9[/tex]
[tex]+ 7 + 7[/tex]
[tex]-9 + 7 = -2[/tex]
[tex]c = -2[/tex]

A baker is deciding how many batches of muffins to make to sell in his bakery. He wants to make enough to sell every one and no fewer. Through observation, the baker has established a probability distribution. x P(x) 1 0.10 2 0.30 3 0.40 4 0.20 What is the probability the baker will sell exactly one batch
Answer:
[tex]P(x = 1) = 0.10[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{ccccc}x & {1} & {2} & {3} & {4} \ \\ P(x) & {0.10} & {0.30} & {0.40} & {0.20} \ \ \end{array}[/tex]
Required
Determine the probability of selling exactly 1 batch
This probability is represented with [tex]P(x = 1)[/tex]
From the table:
When x = 1; P(x) = 0.10
Hence:
[tex]P(x = 1) = 0.10[/tex]
In other words, the probability of selling exactly 1 is 0.10

65,823 - b=41,000 what is the value of b
Answer:
24,823
Step-by-step explanation:
Since we know the answer and the what we're subtracting from we can make an equation like this 65,823 - b = 41,000. Now you solve it by subtracting 65,823 - 41,000 = b. 24,823 = b because if we were to add the smaller numbers like this: 41,000 + 24,823 we would get 65,823 making our answer correct.

Find the cost of 80 Orange at 5 for 30 naria
Answer:
The cost of 80 oranges = 480 nairas
Step-by-step explanation:
Given
The cost of 5 oranges = 30 naira
Determine
The cost of 80 oranges
Given that the cost of 5 oranges = 30 naira
so,
Unit rate = 30 nairas / 5 oranges
= 6 nairas per orange
∴ The cost of 1 orange = 6 nairas
As the cost of 1 orange = 6 nairas
Thus,
The cost of 80 oranges = 6 × 80 = 480 nairas
Hence,
The cost of 80 oranges = 480 nairas
What is the slope of the line?
Answer:
2
Step-by-step explanation:
Answer:
First the line is positive so you can eliminate all negative choices for slope
Now start from a random point that lands on the graph
Now it can’t be 1 becuase it has am extra box but that line isn’t on a point
Now 1/2 it can’t be becuase if you rise 1 and go right 2 it’ll not land ona. Point
But for 2, you rise up 2 and right 1 and you land on a point on the graph so the final answer is 2

Statistical techniques are useful to describe and understand ____________________.

Answer:
Variability
Step-by-step explanation:
Variability in simple terms may be described as differences in measurement or reading of a certain construct or phenomenon. Variability measures include range, standard deviation or variance. In most cases, variation or degree of Variability is measured about a central value called the mean. This is because same measurement about a certain phenomenon or study would usually not yield the same result value. Hence, the mean is used to record the average of these measurement and the differences in each measurement from the mean is also recorded, this is called the standard deviation which is a Variability measure.
Thus VARIABILITY means successive observation of a phenomenon do not yield exactly the same result.
