Answer:
y < 5x + 5
Step-by-step explanation:
find slope and y-intercept first:
for slope I used the formula with these two points: (0,5) and (-1,0) and the y-intercept can be seen at (0,5)
so equation is y = 5x + 5
but we need to select an inequality symbol, because line is dashed it must be either > or <
I used the point (0, 0) to determine the sign:
is this true or false? 0 > 5(0) + 5 False
so the sign must be <
Check: is this true or false? 0 < 5(0) + 5 True

A random sample of 8 Samsung Galaxy smartphones being sold over the Internet in 2013 had the following prices, in dollars:
249 349 299 249 149 135
199169
Assume the population standard deviation is alpha = 85.
If appropriate, construct a 99.5% confidence interval for the mean price for all phones of this type being sold on the Internet in 2013.
Answers
Answer:
The 99.5% confidence interval for the mean price for all phones of this type being sold on the Internet in 2013 is between $140.39 and $309.11
Step-by-step explanation:
Sample mean:
Sum of all values divided by the number of values. So
[tex]S_{m} = \frac{249+349+299+249+149+135+199+169}{8} = 224.75[/tex]
Confidence interval:
We have the standard deviation for the population, so the z-distribution is used.
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.995}{2} = 0.0025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.0025 = 0.9975[/tex], so Z = 2.807.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 2.807\frac{85}{\sqrt{8}} = 84.36[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 224.75 - 84.36 = $140.39
The upper end of the interval is the sample mean added to M. So it is 224.75 + 84.36 = $309.11
The 99.5% confidence interval for the mean price for all phones of this type being sold on the Internet in 2013 is between $140.39 and $309.11

Answer:
n = 1/2 or .5
Step-by-step explanation:
4n + 3 = 10 -10n
14n = 7
n = 1/2 or .5
Hope this helps!
Answer:
n = -0.5
Step-by-step explanation:
4n + 3 = 5(2 - 2n)
First you multiply 2 and 2n by 5
4n + 3 = 10 - 10n
subtract 4n on both sides (meaning subtract 4n by itself on the left side of the equal sign and subtract 10n and 4n)
3 = 10 + 14n
Subtract 10 on both sides
-7 = 14n
Divide on both sides
Your answer should be n = -0.5 (or -0.5 = n)
Hope this helps!

A wedding website states that the average cost of a wedding is $25,809. One concerned bride hopes that the average is less than reported. To see if her hope is correct, she surveys 46 recently married couples and finds that the average cost of weddings in the sample was $24,638. Assuming that the population standard deviation is $5531, is there sufficient evidence to support the bride’s hope at the 0.10 level of significance?
Step 1 of 3 : State the null and alternative hypotheses for the test. Fill in the blank below.
H0Ha: μ=25,809: μ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯25,809
Step 2 of 3 : Find the test statistic
Step 3 of 3 : What is the conclusion?
Answers
Answer:
1)
Null hypothesis H₀ : μ = 25,809
Alternative hypothesis H₁ : μ < 25,809
2) Test Statistic = -1.44
3) Conclusion:
The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.
Step-by-step explanation:
Given the data in the question;
Sample mean x" = 24,638
sample size n = 46
standard deviation σ = 5531
level of significance ∝ = 0.10
NULL and ALTERNATIVE HYPOTHESIS
Null hypothesis H₀ : μ = 25,809
Alternative hypothesis H₁ : μ < 25,809
TEST STATISTICS
Z = (x"-μ) / σ√n
we substitute
Z = (24,638 - 25,809) / (5531/√46)
Z = -1171 / 815.5
Z = -1.44
Test Statistic = -1.44
Now, from normal z-table;
P-value = P( Z < -1.44 ) = 0.0749
P-value = 0.0749
Since P-value ( 0.0749 ) is less than level of significance ( 0.10 ), we reject H₀.
Conclusion:
The result is significant, there is sufficient evidence to support the bride’s hope at the 0.10 level of significance.

Answers
Answer:
197 adult tickets and 354 child tickets were sold for the event.
Step-by-step explanation:
Given that the Family Fine Arts Center charges $ 22 per adult and $ 14 per child under 12 years old for its performances, and on a recent weekend evening when 551 people paid admission, the total receipts were $ 9290, to determine how many who paid were children under 12 years old the following calculation must be performed:
22 - 14 = 8
551 x 14 = 7.714
9,290 - 7,714 = 1,576
1,576 / 8 = 197
551 - 197 = 354
197 x 22 + 354 x 14 = X
4.334 + 4.956 = X
Therefore, 197 adult tickets and 354 child tickets were sold for the event.

Step-by-step explanation:

For the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.
What are quartiles?When we get data which can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.
Quartiles are then selected as 3 points such that they create four groups in the data, each groups approximately possessing 25% of the data.
Lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.
Similarly, second quartile (also called median) is approximately in mid of the data.
Third quartile (also called upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.
Left to right is said in assumption that data was arranged increasingly from left to right
For this case, it is said that 25% of the class weighted less than 6 pounds 1 ounce. That means it is first quartile or say lower quartile.
Thus, for the considered case, the weight 6 pound 1 ounce will be taken as : Option C: Lower quartile.

Write the equation for the circle with center (2, 4) and radius 7 in standard form
Answers
Answer:
Step-by-step explanation:
Let's get the equation first and then look at the circle when it has been graphed.
(x - 2)^2 + (y - 4)^2 = 7^2
(x - 2)^2 + (y - 4)^2 = 49
You will notice that the center of the circle has been marked and it is at (2,4) just as the question required.Another point has been added. It is at (2,11).It is the radius of the circle11 - 4 = 7 which is the radius that has been requestedAccording to the eScience Lab Manual for Lab 1, Experiment 3, you need to prepare 65 ml of 60% soda/syrup prescription. To do this you can use the 80% soda solution and the syrup solution (0% strength) that you have in inventory. How many mls of soda solution do you need to create this final solution?
Answers
Answer:
16.25 mL
Step-by-step explanation:
Since we are mixing from the syrup in the inventory, we can say that the syrup in the inventory must be equal to that in the final solution. Thus, we will use the dilution equation to solve for the Initial volume;
Dilution equation is;
V₁C₁ = V₂C₂
Where;
V₁ is initial volume
C₁ is initial concentration or initial molarity
V₂ is final volume
C₂ is final concentration of final molarity
We are given;
C₁ = 80% = 0.8
C₂ = 60% = 0.6
V₂ = 65 mL
Making V₁ the subject in the dilution equation, we have;
V₁ = (V₂C₂)/C₁
V₁ = (65 × 0.6)/0.8
V₁ = 48.75 mL of inventory syrup
Since we have 48.75 mL of inventory syrup and the dilute solution is 65 ml, then the volume of soda solution required = 65mL - 48.75 mL = 16.25 mL
