Construct the indicated confidence interval for the population mean using the t-distribution. Assume the population is normally distributed.
picture of question below
Using the t-distribution, it is found that the confidence interval is (14.2, 14.8).
What is a t-distribution confidence interval?The confidence interval is:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
In which:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 18 - 1 = 17 df, is t = 2.1098.
The other parameters are given by:
[tex]\overline{x} = 14.5, s = 0.68, n = 18[/tex].
Hence, the bounds of the interval are given by:
[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 14.5 - 2.1098\frac{0.68}{\sqrt{18}} = 14.2[/tex]
[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 14.5 + 2.1098\frac{0.68}{\sqrt{18}} = 14.8[/tex]
The confidence interval is (14.2, 14.8).

Let's Apply Solve for the surface area of the following figures.
please i need this rn
Answer:
Step-by-step explanation:
1) Surface area of a square = s*s = 12*12 = 144 in
2) Surface area of a Cone = A=πr(r+h2+r2) = 3.142*4(4+22*2+4*2) = 351.904 cm^2
3) S.A of a Cylinder =2πrh+2πr2 = 2*3.142*2*14 + 2*3.142*2*2 = 201.088 m^2
4) S.A of a square Pyramid = a^2 + 2a squareroot (a^2/4 + h^2) = 516.5m^2
5) S.A of a Sphere = 4*pie*r^2 = 4* 3.142*15^2 = 2827.8mm^2

5x/2 = 10
multiply both sides by 2
5x = 20
divide both sides by 5
x=4
Answer:
x=4
Step-by-step explanation:
5x-2=18 (multiply 9 with 2=18)

3. Amy Schorling is age 24 and is unmarried. She uses her vehicle
for business. Her driver-rating factor is 1.85. Her vehicle is
classified D-14. Her insurance consists of $25,000 property
damage, 25/50 bodily injury, $50-deductible comprehensive, an
no collision coverage.
a. What is her annual premium?
b. How much is her annual premium if she includes
$50-deductible collision coverage?
Based on Amy Schorling's driver rating factor, vehicle classification and bodily injury coverage, her annual premium is $576.46.
If she includes the $50-deductibel collision coverage, her insurance premium becomes $1,067.08.
How much is Amy Schorling's annual premium?At $25,000 property damage, her 25/50 bodily injury coverage premium is $206.40.
This should be added to her $50 comprehensive deductible D-14 vehicle classification of $105.20.
Annual base premium:
= 206.40 + 105.20
= $311.60
Annual premium:
= Annual base premium x Driver rating factor
= 311.60 x 1.85
= $576.46
How much is the annual premium including collision coverage?The annual base premium becomes:
= 311.60 + 265.20
= $576.80
Annual premium becomes:
= 576.80 x 1.85
= $1,067.08

Answer:
Step-by-step explanation:
for number 8 we have to use the equation πr^2, so plugging 9 into the equation would give us π(9^2). squaring the 9 gives us 81, and 81 times π equals ~25.
for number 9 we need to use the same equation, πr^2 to find the area, but since we are given the diameter we do not need to use r^2. Instead, we can use π(106) which gives us 333.
Determine the finance charge on a $6,800 car loan if monthly payments were $158.50 for 48 months.
Answer:
808
Step-by-step explanation:
Plan
You make 48 payments of 158.50. That gives you the total of what you have paid back.
Equation
Total payment = months * monthly payments
Solution
Total Payment = 48 * 158.50
Total Payment = 7608
Cost of the loan
Finance charge = amount paid - amount loaned
Finance charge = ?
amount paid = 7608
amount loaned = 6800
Finance charge = 7608 - 6800
Answer: Finance charge = 808

Angles A and C are supplementary. Find the measure of angle C.
A. List 2 pairs of angles in square CDFG that are complementary.
B. Name three angles that sum up to 180°
a. Two pairs complementary angles are: ∠DCM and ∠DMC; ∠MGF and ∠GMF
b. m∠GMF + m∠CMG + m∠DMC = 180°
What are Supplementary Angles and Complementary Angles?If the sum of two angles equal 90°, they are complementary angles.
If the sum of two angles equal 180°, they are supplementary angles.
Given square CDFG:
a. Two pairs of angles that are complementary are: ∠DCM and ∠DMC; ∠MGF and ∠GMF
b. m∠GMF + m∠CMG + m∠DMC = 180° (angles on a straight line)
Therefore, three angles that sum up to 180° are: ∠GMF, ∠CMG, and ∠DMC.
