Isabelle was curious if sample maximum was an unbiased estimator of population maximum. She started
with a large normally distributed population of test scores whose maximum was 99 points.
She then took a random sample of 6 tests and calculated the maximum of the sample. She replaced those
tests and repeated this process for a total of 40 trials. Her results are summarized in the dotplot below,
where each dot represents the maximum score from a sample of 6 tests.

Sample maximum
Answer: sample maximum appears to be biased estimator since it consistently underestimated the population maximum
Answer: Sample maximum appears to be biased estimator since it consistently underestimated the population maximum.
Step-by-step explanation:
make a number line and show all values of that x that x < -1 and x > 1
Hey I’d be happy to help!
1st you have to draw your blank number line (make it a decent length
<———————————————————>
Then you have to label your 0 that will separate all positive and negative numbers you put
On the right side of 0 your going to have positive numbers (1,2,3,4,5,6)
And on the left side of zero, it’s gonna be negative numbers.
Then the tricky part:
Your going to make a line from -1 to 1 on your number line. Then because your greater then and less than signs do not have an “or equal to” line... your gonna put an open circle around -1 and 1 to show that x<-1 and X>1

The diameter of a circle is 1.4 centimeters. Find its area. Use 3.14 Round to the nearest
hundredth
Answer:
Area = 1.54
Step-by-step explanation:
Area = π[tex]r^{2}[/tex]
π = 3.14
diameter = 1.4
radius (half of diameter) = 0.7
Area = 3.14 x [tex]0.7^{2}[/tex]
Area = 3.14 x 0.49
Area = 1.5386
round to the nearest hundredth:
1.5386 = 1.54

A triangle has sides with lengths of 10 centimeters, 23 centimeters, and 26 centimeters. Is it
a right triangle?
Answer:
No, it is not a right triangle. It is an obtuse triangle.
Step-by-step explanation:
How to know a right traingle
A right triangle is a triangle in which one of the angles is a 90∘ angle. The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.
A circle has a radius of 6 inches and a central angle of 60°. What is the measure of the arc length associated with this angle?
Answer:
[tex]2\pi[/tex]
Step-by-step explanation:
first you take 60°/360°= 1/6 then you take 1/6 and multiple it by [tex]2\pi[/tex] and that equals [tex]\frac{\pi }{3}[/tex] finally take [tex]\frac{\pi }{3}[/tex] times the radius (6) and that should equal [tex]2\pi[/tex]

The measure of the arc length associated with the angle is 2π inches OR 6.28 inches
Calculating the length of an arcFrom the question, we are to determine the measure of the arc length
The measure of the arc length can be calculated by using the formula,
[tex]l = \frac{\theta}{360 ^\circ}\times 2\pi r[/tex]
Where [tex]l[/tex] is the length of the arc
θ is the central angle
r is the radius of the circle
From the given information,
r = 6 inches
θ = 60°
Putting the parameters into the formula, we get
[tex]l = \frac{60 ^\circ}{360 ^\circ}\times 2 \pi \times 6[/tex]
[tex]l = \frac{1}{6}\times 2 \pi \times 6[/tex]
[tex]l =2\pi[/tex] inches OR 6.28 inches
Hence, the measure of the arc length associated with the angle is 2π inches OR 6.28 inches

Factor completely
486+108x+6x^2
Thank you!
Answer:
6(x + 9) (x + 9)
or
[tex]6 (x+9)^{2}[/tex]
Step-by-step explanation:
[tex]468 + 108x + 6x^{2} \\6x^{2} +108x + 468[/tex]
Greatest common factor of 6, 108, and 486:
6 x 1 = 6
6 x 18 = 108
6 x 81 = 486
GCF: 6
so:
[tex]6(x^{2} +18x +81)[/tex]
[tex]x^{2} +18x + 81[/tex]
factors to:
(x + 9) (x + 9)
because:
9 x 9 = 81
9 + 9 = 18
So:
It factors completely too:
6(x + 9) (x + 9)
or
[tex]6 (x+9)^{2}[/tex]
which expression is a factor of x^2-5x-6

(x - 6)(x + 1)Step-by-step explanation:
These are the factors
First, find the factors of 6 6 / / \ \ 1 2 3 61 and 6 make 52 and 3 also make 5But which one makes -5-3+2=-1 -2+3=1So not 2 and 3-1+6=5 -6+1=-51 and -6 worksThis means the factors as (x - 6) and (x + 1).Hope this helps,

Answer:
c. x= 28°, y= 76°
Step-by-step explanation:
y= 180-104=76°
104= x+y (property of triangle, exterior angles is equal to the sum of opposite interior angles)
x=104-76= 28°
Previous data estimates the proportion of adults who are fully literate in Colombia to be 0.92. Suppose a random sample of adults from Columbia is to be taken and used to construct a 95% confidence interval for the proportion of adults who are fully literate. What is the MINIMUM sample size which should be used to construct this interval if the margin of error for the interval is to be 0.03 or less
Answer:
The minimum sample size which should be used is 315.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
Previous data estimates the proportion of adults who are fully literate in Colombia to be 0.92.
This means that [tex]\pi = 0.92[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
What is the MINIMUM sample size which should be used to construct this interval if the margin of error for the interval is to be 0.03 or less?
The minimum sample size that should be used is n for which M = 0.03. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.92*0.08}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.92*0.08}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.92*0.08}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.92*0.08}}{0.03})^2[/tex]
[tex]n = 314.2[/tex]
Rounding up
The minimum sample size which should be used is 315.

expression that is equivalent to 7 3/4 + 3 5/6 - 1 3/4 that uses addition instead of subtraction.
Answer:
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6
Step-by-step explanation:
we do not want the minus sign.
7 3/4 + 1 3/4 - 3 5/6 = 7 3/4 + 1 3/4 - 3 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 7+ 3/4 + 1 + 3/4 - 3 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 7 + 1 - 3 + 3/4 + 3/4 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 5 + 3/4 + 3/4 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6
A bookstore tracked the data of the weight of their deliveries and the number of books in each box. They created a
scatterplot and trend line based on the data.
Weight (lbs)
4
2
1
6
8 9 10
Number of Books
Which statement would be a reasonable prediction based on the scatterplot and trend line?
A box with 10 books should weigh about 2 pounds.
A box with 10 books should weigh about 4 pounds.
A box with 10 books should weigh about 6 pounds.
A box with 10 books should weigh about 12 pounds.
Answer: I am taking the test rn and I think its (C) Since the trend line is a positive correlation and slope, so then a good estimate would be 6
