4. Which set of ordered pairs represents a function?
(1) {(0,4), (2,4),(2,5)}
(2){(6,0), (5,0),(4,0)}
(3) {(4,1),(6,2), (6,3), (5,0)}
(4) {(0,4),(1,4), (0,5),(1,5)}
Answer: (2) {(6,0), (5,0),(4,0)}
It is a function, where each value is associated with exactly one output.
Step-by-step explanation:
A relation is said to be a function if the first components of the ordered pairs are associated with exactly one value of the second components of the ordered pair.
(1) {(0,4), (2,4),(2,5)}
here 2 is associated with 2 different values of second component.
Thus it is not a function.
(2) {(6,0), (5,0),(4,0)}
It is a function, where each value is associated with exactly one output.
(3) {(4,1),(6,2), (6,3), (5,0)}
It is not a function as 6 is associated with 2 different values of second component.
(4) {(0,4),(1,4), (0,5),(1,5)}
It is not a function as 0 and 1 are associated with 2 different values of second component.

Answer:
x < 0
Step-by-step explanation:
If you were to graph the function, you would get a parabola that opens down with the vertex at (0, 0). So, the graph is increasing from -∞ to 0.
A satellite system consists of 4 components and can function if at least 2of them are working. If each component independently works with probability 0.8, what is the probability the system will function?
Answer:
X follows binomial distribution with n=4, p=0.6, q= 0.4. To make the system function adequately, at least 2 components should work well.
Step-by-step explanation:
Hope this helps
Answer:
0.9728
Step-by-step explanation:
We have 2 options for the system to fail - no components work, or only one works.
The probability that no components work is:
[tex]0.2^4 = 0.0016[/tex]
The probability that one SPECIFIC component works and the others failed is:
[tex]0.2^3 \cdot 0.8 = 0.0064[/tex]
And because there's 4 components, the chance that EXACTLY ONE works but the others don't is:
[tex]4 \cdot 0.0064 = 0.0256[/tex]
So we sum the probabilities:
[tex]P_{failure} = 0.0016 + 0.0256 = 0.0272\\P_{works} = 1 - P_{failure} = 0.9728[/tex]

A student records the repair cost for 17 randomly selected TVs. A sample mean of $73.10 and standard deviation of $16.01 are subsequently computed. Determine the 90% confidence interval for the mean repair cost for the TVs. Assume the population is approximately normal. Step 1 of 2: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

In semiconductor manufacturing, wet chemical etching is often used to remove silicon from the backs of wafers prior to metalization. The etch rate is an important characteristic in this process and known to follow a normal distribution. Two different etching solutions have been compared, using two random samples of 10 wafers for each solution. Assume the variances are equal. The etch rates are as follows (in mils per minute):
Solution 1 Solution 2
9.9 10.6 10.5 10.2
9.4 10.3 10.6 10.2
9.3 10.0 10.7 10.7
9.6 10.3 10.4 10.4
10.2 10.1 10.5 10.3
Required:
a. Construct normal probability plots for the two samples. Do these plots provide support for the assumptions of normality and equal variances? Write a practical interpretation for these plots.
b. Do the data support the claim that the mean etch rate is the same for both solutions? In reaching your conclusions, use α = 0.05 and assume that both population variances are equal. Calculate a P-value.
c. Find a 95% confidence interval on the difference in mean etch rates

What is the sum of 50.249 + 21.3
Answer:
71.549
Step-by-step explanation:
Answer:
The sum of 50.249 + 21.3 is 71.549.
Step-by-step explanation:
50.249 + 21.3 can be written as (50 + 20) + (0 + 1) + (0.2 + 0.3) + 0.049, which makes calculating the sum easier. 50 + 20 = 70, 0 + 1 = 1, 0.2 + 0.3 = 0.5, and you still have a 0.049. Add the numbers all together and you'll get that the sum of 50.249 and 21.3 is 70 + 1 + 0.5 + 0.049 or 71.549.

The point (-2, k) lies on the line 2x – 4y + 3 = 0.
Find the value of k.
Answer:
k = (-1/4)
Step-by-step explanation:
Given that,
The point (-2, k) lies on the line 2x – 4y + 3 = 0.
We need to find the value of k.
Put x = -2 and y = k in the given equation.
2(-2) – 4k + 3 = 0
-4-4k = -3
-4+3 = 4k
-1 = 4k
k = (-1/4)
So, the value of k is equal to (-1/4).

Step-by-step explanation:
A store sells 8 cans of for $22. How much would it cost you to buy 3 cans of fruit cocktail? ?
the answer is 8.25 or 8 1/4
you can get this by dividing 22 by 8 to see the price for one can. this gives you 2.75
now you want to know how much 3 cans would cost. we know one can costs 2.75, so we multiply that by 3.
this would give you 8.25 which is your answer
if this was useful please mark brainliest! （>∀<）
Answer:
3 cans of fruit cocktail would cost $8.25
