Domain and range of graph need ASAP
Answers
Answer:
Domain: [tex]-6 \leq x \leq 3[/tex]
Range: [tex]-3 \leq x \leq 6[/tex]
Step-by-step explanation:
The domain is the set of real values which can be inputted into a function and produce a real output. In this case, the domain is the following: [tex]-6 \leq x \leq 3[/tex], because this is the set of real values for which the function will produce a real output.
The range is the set of real values which a function outputs when a value from the domain is entered into the function. This is the set of y-values that one can see on the graph, the possible y-values are in between (-3) and (6).

A sample of 26women is obtained, and their heights (in inches) and pulse rates (in beats per minute) are measured. The linear correlation coefficient is 0.208and the equation of the regression line is ModifyingAbove y with caret equals 17.8 plus 0.940 x,where x represents height. The mean of the 26heights is 63.5in and the mean of the 26pulse rates is 77.9beats per minute. Find the best predicted pulse rate of a woman who is 71in tall.
Answers
Answer:
The pulse rate is 84.54bpm
Step-by-step explanation:
Given
[tex]\^{} y = 17.8 + 0.940x[/tex]
Required
Find [tex]\^{}y[/tex] when [tex]x = 71[/tex]
Substitute 71 for x in: [tex]\^{} y = 17.8 + 0.940x[/tex]
[tex]\^{} y = 17.8 + 0.940 * 71[/tex]
[tex]\^{} y = 17.8 + 66.74[/tex]
[tex]\^{} y = 84.54[/tex]
The pulse rate is 84.54bpm

[tex] \therefore \frac{TP}{SQ} = \frac{PR}{QR}[/tex]
[tex] \therefore \frac{TP}{SQ} = \frac{PQ+QR}{QR}[/tex]
[tex] \therefore \frac{3}{x} = \frac{1\frac{1}{3} +2 \frac{2}{3}}{2 \frac{2}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{\frac{4}{3} + \frac{8}{3}}{\frac{8}{3}}[/tex]
[tex] \therefore \frac{3}{x} = \frac{\frac{12}{3}}{\frac{8}{3}}[/tex]

isosceles right
scalene acute
scalene right
equilateral right
Answers
Answer:
scalene right
Step-by-step explanation:
A scalene right has no equal side lengths, has a right side(90) and will have two angles less than 90 because all three triangle sides need to equal to be 180. So scalene right is your answer. Hope that helped!

A lab is testing the amount of a certain active chemical compound in a particular drug that has been recently developed. The manufacturer claims that the average amount of the chemical is 95 mg. It is known that the standard deviation in the amount of the chemical is 5 mg. A random sample of 25 batches of the new drug is tested and found to have a sample mean concentration of 89.9 mg of the active chemical.
Calculate the 95% confidence interval for the mean amount of the active chemical in the drug. Give your answers to 2 decimal places. (suppose to be number less than and equal to mean less than and equal to another number)
Answers
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,
[tex]\bar{x}[/tex] = 89.9 mg
Amount of chemical,
σ = 5
α = 0.05
The critical value from Z table will be:
= [tex]Z(\frac{\alpha}{2} )[/tex]
= [tex]Z(\frac{0.05}{2} )[/tex]
= [tex]1.96[/tex]
Now,
The confidence interval will be:
= [tex]\bar{x} \pm Z(\frac{\alpha}{2} )\times \frac{\sigma}{\sqrt{n} }[/tex]
On substituting the values, we get
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{\sqrt{25}}[/tex]
= [tex]89.9 \pm Z(\frac{0.05}{2})\times \frac{5}{5}[/tex]
= [tex]89.9 \pm1.96\times 1[/tex]
Lower limit will be:
= [tex]89.9 -1.96\times 1[/tex]
= [tex]87.94[/tex]
Upper limit will be:
= [tex]89.9 +1.96\times 1[/tex]
= [tex]91.86[/tex]

1 x 1 x 1 = 1To the nearest 1000, there are 18,000 people at a festival . Write down the minimum possible number of people at the festival
Answers
Answer:
17500
Step-by-step explanation:
17499 rounds down
17500 rounds up
The number of people is an illustration of approximation and estimation
The minimum possible number of people at the festival is 17500
The approximated number of people is:
People = 18000
Because 18000 represents people, it means that the population is a whole number
The smallest whole number that can be approximated to 18000 is 17500
i.e.
People = 17500
Hence, the minimum possible number of people at the festival is 17500

In the last several weeks, 18 days saw rain and 29 days saw high winds. in the same time period 7 days saw both rain and high winds. How many days saw either rain or high winds
Answers
Answer:
40 days saw either rain or high winds
Step-by-step explanation:
We solve this question using Venn sets.
I am going to say that:
Set A: Rain
Set B: High winds.
18 days saw rain
This means that [tex]A = 18[/tex]
29 days saw high winds
This means that [tex]B = 29[/tex]
7 days saw both rain and high winds.
This means that [tex]A \cap B = 7[/tex]
How many days saw either rain or high winds?
This is
[tex]A \cup B = A + B - A \cap B[/tex]

Answers
Answer:
[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]
Step-by-step explanation:
Given [Missing]
[tex]A = (-3,4)[/tex]
[tex]B = (1,3)[/tex]
[tex]C =(3,6)[/tex]
[tex]D =(1,6)[/tex]
The first transformation: reflection across the y-axis.
The rule is: [tex](x,y)==>(-x,y)[/tex]
So:
[tex]A = (-3,4)[/tex] ==>[tex]A' = (3,4)[/tex]
[tex]B = (1,3)[/tex] ==> [tex]B' = (-1,3)[/tex]
[tex]C =(3,6)[/tex] ==> [tex]C' = (-3.6)[/tex]
[tex]D =(1,6)[/tex] ==> [tex]D' = (-1,6)[/tex]
Translation 2 units down
The rule is: [tex](x,y)==>(x,y-2)[/tex]
So:
[tex]A' = (3,4)[/tex] ==> [tex]A" =(3,4-2) =(3,2)[/tex]
[tex]B' = (-1,3)[/tex] ==> [tex]B" = (-1,3-2) = (-1,1)[/tex]
[tex]C' = (-3.6)[/tex] ==> [tex]C" = (-3,6-2) = (-3,4)[/tex]
[tex]D' = (-1,6)[/tex] ==> [tex]D" =(-1,6-2) = (-1,4)[/tex]
Hence:
[tex]A" = (3,2)\ \ B" = (-1,1)\ \ C" =(-3,4)\ \ D =(-1,4)[/tex]
