The probability that at least 1 doesn't use a computer at work is 0.8065.
The probability that all 5 use a computer in their jobs is 0.1935.
What is a probability function?Suppose we let X represent the no. of women that make use of computers at work. A given random variable X which approaches a binomial distribution with the following data n = 5 and p = 0.72 has a probability function:
[tex]\mathbf{P(X=x) = \left \{ {{(^5_x)(0.72)^x(0.28)^{5-x}, \ X = 0,1,2,...5} \atop {0, \ \ \ \ \ \ \ \ \ \ \ \ elsewhere }} \right.}[/tex]
a.)
Then, the probability that at least 1 doesn't use a computer at work can be computed as:
[tex]\mathbf{1-P(X=5) =1 - (^5_5)(0.72)^5(0.28)^{5-5}}[/tex]
[tex]\mathbf{1-P(X=5) =1 - (0.72)^5}[/tex]
[tex]\mathbf{1-P(X=5) =1 - 0.1935}[/tex]
⇒ 0.8065
b.)
The probability that all 5 make use of computers at their job is;
[tex]\mathbf{P(X=5) = (^5_5) (0.72)^5 (0.28)^{5-5}}[/tex]
[tex]\mathbf{P(X=5) = 1 \times (0.72)^5 \times 1}[/tex]
P(X = 5) = 0.1935

Which of the following is not a measure of the center of a data set?
(1) the median
(2) the mean
(3) the range
(4) the mode
Answer:
i think its 4.
Step-by-step explanation:
The Range is not used to measure of the center of a data set.
Here,
We have to find, which is not a measure of the center of a data set.
What is Range?
The range of a set of data is the difference between the largest and smallest values.
Now,
Median is the middle number, when data is arranged in numerical order.
Mean is the average of a data set.
Mode is the data item the appears most frequently.
Hence,
Median, Mean, Mode all are used to measure of the center of a data set.
So, Only The Range is not used to measure of the center of a data set.

If
f (x) = x^2 - 4
what is the average rate of change from x = 3 to x = 5?
Answer:
The average rate of change is 8
Step-by-step explanation:
Mathematically, we have the average rate of change over a given interval as;
f(b) - f(a)/b-a
Where the interval is [a,b]
With respect to this question, a = 3 and b = 5
f(a) = f(3) = 3^2 - 4 = 9-4 = 5
f(b) = f(5) = 5^2 - 4 = 25-4 = 21
Thus, the average rate of change over the intervals will be;
(21-5)/(5-3) = 16/2 = 8

A sample of adults was asked to choose their favorite sport to watch from a list of four sports. Age Range 18-30 31-50 51+ Total Sport Football 15 19 17 51 Baseball 7 12 18 37 Basketball 15 8 11 34 Soccer 12 9 6 27 Total 49 48 52 149 Given that an adult likes soccer, what is the probability the adult is aged 18–30?
The probability that an adult who likes soccer ages 18-30 is approximately 0.444.
Given that the table is,
Age range
18-30 31-50 51+ Total
Football 15 19 17 51
Sport Baseball 7 12 18 37
Basketball 15 8 11 34
Soccer 12 9 6 27
Given:
Liked sport: Soccer
Age range: 18-30
To find the probability that an adult is aged 18-30 given that they like soccer, denoted as P(18-30 | S).
To calculate this probability, use the formula for conditional probability:
[tex]P(18-30 | S)= \frac{P((18-30) \cap (S))} {P(S)}[/tex]
P(18-30 ∩ Soccer) represents the probability that an adult is both aged 18-30 and likes soccer.
Looking at the provided table, the number of adults who like soccer and are aged 18-30 is 12.
P(Soccer) represents the probability that an adult likes soccer. The total number of adults who like soccer, regardless of age, is 27.
Now, calculate the probability:
P(18 - 30| S) = 12 / 27
≈ 0.444 (rounded to three decimal places)

A bag contains one green marble, two yellow marbles, four blue marbles and five red marbles. How many blue marbles would you need to add to make the probability of drawing a blue marble 1/2?
Answer:
You would have to add 4 blue marbles
Step-by-step explanation:
there are a total of 12 marbles, 4 of them being blue.
If you add 4 blue ones, there would be a total of 16 marbles and 8 of them would be blue.
8/16 = 1/2
Therefore, 4 blue marbles need to be added for the chance to draw one to be 1/2 or 50%
Answer:
Step-by-step explanation:
Since there is 1 green, 2 yellow, 4 blue, and 5 red we start with 12 marbles. For the probability of picking a blue to be 1/2 we must satisfy.
(b+x)/(12+x)=1/2. (Where x is the number of blue marbles added)
2(b+x)=12+x
2b+2x=12+x
2b+x=12
x=12-2b, since we started with 4 blue marbles
x=12-2(4)
x=12-8
x=4
So we would need to add 4 blue marbles to make the probability of picking a blue 1/2.

Dairy bar 25 kg of fish flavored cat food and 35 kg of chicken flavored cat food for the cat rescue center he's going to divide the cat food and two packets of 300 g how many packets will he make
Answer:
200 packets
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Fish flavoured = 25kg or 25,000 gm
Chicken flavoured = 35 kg or 35,000 gm
Packets size = 300gm
So, we can calculate the number of packets by using following formula,
Number of packets = (25,000gm + 35,000gm) ÷ 300gm
Number of packets = 60,000 gm ÷ 300gm
Number of packets = 200 packets
