State the domain and range in set notation
Answer:
Image result for State the domain and range in set notation
The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range. Domain: all x-values that are to be used (independent values).

A line passes through (0, 2) and has a slope of 3. Which function's graph is parallel to this line?
A. f(x) = 2 O
B. f(x) = 3 O
C. f(x) = 2x O
D. f(x) = 3x o TUL earch
ANSWER IS B 30
Step-by-step explanation:
The function's graph is parallel to this line is 3x.
What is equation of a straight line ?The general equation of a straight line is y = mx + c, where m is the gradient or slope, and y = c is the value where the line cuts the y-axis. This number c is called as intercept.
From the question,
Parallel lines have same slope.
The slope given, m =3.
The function's graph is parallel to this line is 3x.
Hence the required answer is f(x)= 3x.

A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovens is greater than the repair cost for type II ovens. A sample of 61 type I ovens has a mean repair cost of $79.60, with a standard deviation of $23.47. A sample of 45 type II ovens has a mean repair cost of $75.25, with a standard deviation of $15.07. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let μ1 be the true mean repair cost for type I ovens and μ2 be the true mean repair cost for type II ovens.Step 3 of 4 : Determine the decision rule for rejecting the null hypothesis H0. Round the numerical portion of your answer to three decimal places.
The question is missing some parts. Here is the complete question.
A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovens is greater than the repair cost in type II ovens. A samplle of 61 type I ovens has a mean repair cost of $79.60, with a standard deviation of $23.47. A sample of 45 type II ovens has a mean repair cost of $75.25, with standar deviation of $15.07. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let [tex]\mu_{1}[/tex] be the true mean repair cost for type I ovens and [tex]\mu_{2}[/tex] be the true mean repair cost for type II ovens.
Step 1 of 4: State null and alternative hypothesis for the test.
Step 2 of 4: Compute the value of test statistics. Round your answer to 2 decimal places.
Step 3 of 4: Determine the decision rule for rejecting the null hypothesis. Round the numerical portion of your answer to 3 decimal places.
Step 4 of 4: Make the decision for the hypothesis test. (Reject or fail to reject Null Hypothesis)
Answer and Step-by-step explanation:
First, state null and alternative hypothesis:
[tex]H_{0}: \mu_{1}=\mu_{2}[/tex]
[tex]H_{a}: \mu_{1}>\mu_{2}[/tex]
Use z-statistics:
[tex]z = \frac{x_{1}-x_{2}}{y}[/tex]
where x₁ and x₂ are the means and:
[tex]y=\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}} }[/tex]
Calculating value of test stattistic:
[tex]y=\sqrt{\frac{(23.47)^{2}}{61}+\frac{75.25^{2}}{45} }[/tex]
[tex]y = \sqrt{9.030+5.046}[/tex]
[tex]y = \sqrt{14.076}[/tex]
y = 3.752
[tex]z = \frac{79.6-75.25}{3.752}[/tex]
z = 1.16
The test statistics is z = 1.16
The decision rule for rejecting null hypothesis is: [tex]\alpha[/tex] ≤ test statistics
Using z-score table, it is possible to determine p-value, which is:
p-value = 0.877
Comparing p-value with level of significance (α = 0.05):
0.877 > 0.05
Therefore, we fail to reject the null hypothesis.
The tree in Juan's backyard is 7.7 m high. How high is it in centimeters?
Answer:
770 cm :)
Step-by-step explanation:
1m is 100cm so just multiply 7.7 by 100
The tree in Juan's backyard is 7.7 m high.
To Find:How high is it in cm.
Conversion:1 m = 100 cm
7 m = 7 × 100 = 700 cm
Solution:7.7 m = ( 700 + 70 ) cm = 770 cm
Answer:770 cm
Therefore, it is 770 cm high.
a gallon of paint can cover about 350 square feet of wall space. You have measured a wall to be 210 inches by 120 inches. Will one gallon of paint be enough to cover the wall?
1 foot = 12 inches.
210/12 = 17.5 feet
120/12 = 10 feet
17.5 x 10 = 175 square feet
175 is less than 350 so yes one gallon will be enough.
Answer: yes
Step-by-step explanation: because it is only 175 ft of wall

* For his phone service, Goran pays a monthly fee of $24, and he pays an additional $0.06 per minute of use. The least he has been charged in a month is $93.96
*What are the possible numbers of minutes he has used his phone in a month?
*Use m for the number of minutes, and solve your inequality for m.
Answer:
[tex]m \geq 1166[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = \$24[/tex]
[tex]Charges = \$0.06[/tex] per minute
[tex]Least\ Monthly\ Charges = \$93.96[/tex]
Required
Determine the possible number of minutes
If for 1 minute, he's charged $0.06;
He'll be charged $0.06m for m minutes
Representing this as an inequality, we have:
[tex]Base\ Amount + m\ Charges \geq\ Least\ Monthly\ Charges[/tex]
[tex]24 + 0.06m \geq 93.96[/tex]
Solve for 0.06m
[tex]0.06m \geq 93.96 - 24[/tex]
[tex]0.06m \geq 69.96[/tex]
Solve for m
[tex]m \geq 69.96/0.06[/tex]
[tex]m \geq 1166[/tex]
This implies that, he's charged for at least 1166 minutes

A standardized exam's scores are normally distributed. In a recent year, the mean test score was and the standard deviation was . The test scores of four students selected at random are , , , and . Find the z-scores that correspond to each value and determine whether any of the values are unusual.
Answer:
The following are the solution to this question:
Step-by-step explanation:
In the given question, some of the values are missing which is defined in the attached file please find it.
In this question, the data is used to represent a standardized exam's scores, which is normally spread out into the test score that is 1530 and its standard deviation 316.
Formula:
[tex]\to z=\frac{X- \mu}{\sigma } \\[/tex]
If the value of z-score= 1930
[tex]\to z =\frac{1930- 1530}{316 } \\\\ \to z =\frac{400}{316 } \\\\ \to z = 1.27[/tex]
The z-score is 1.27
If the value of z-score= 1250
[tex]\to z =\frac{1250- 1530}{316 } \\\\ \to z =\frac{-280}{316 } \\\\ \to z = -0.886[/tex]
The z-score is -0.886
If the value of z-score= 2250
[tex]\to z =\frac{2250- 1530}{316 } \\\\ \to z =\frac{720}{316 } \\\\ \to z = 2.27[/tex]
The z-score is = 2.27
If the value of z-score= 1420
[tex]\to z =\frac{1420- 1530}{316 } \\\\ \to z =\frac{-110}{316 } \\\\ \to z = -0.348[/tex]
The z-score is = -0.348

Answer:
Permutation
Step-by-step explanation:
The term to describe the given statement is permutation.
When defining permutation, certain keywords such as order does matter and arrangement are used to describe permutation.
Take for instance:
The arrangement of 3 boys on a seat
Ways 4 friends can sit to take photographs
...are examples of permutation
Permutation of r objects in n distinct objects is calculated as:
