Answer:
White dwarfs are much more common than black holes in galaxies. The reason for this is that black holes are the remnants (final states) of extremely massive stars (> 25 solar masses) while white dwarfs are the remnants of intermediate and low mass stars (< 10 solar masses).
Explanation:
The distribution of weights for newborn babies is approximately normally distributed with a mean of 7.3 pounds and a standard deviation of 0.6 pounds.
Answer:
The required probability will be "0.16".
Explanation:
The one standard deviation above the mean will be:
⇒ [tex]7.9 = 7.3 + 0.6[/tex]
As per the usual distribution empirical principle or theorem, 68 percent including its measurements fall within the same standardized deviation from the mean that would be 32 percent just outside of the limit, implying that= [tex]\frac{32}{2}[/tex]
= [tex]16 \ percent[/tex]
Including its observations lie from an outside distance along both sides.Identify the types of sampling errors that exist in the following sampling designs: (4 points)

Explanation:
I got it wrong with this answer
The types of sampling errors that exist in the following sampling designs will be nonresponse, voluntary, and convenience.
For the first question, it should be noted that everyone cannot respond as only the people who have strong opinions will respond. Therefore, it's a nonresponse error.
For the second question, the people will have to volunteer. Therefore, it's a voluntary bias while the third one is a convenience sample as it's an easily available sample.

Construct a 99% confidence interval of the population proportion using the given information. x=60 n=300
The 99% confidence interval of the population proportion is 0.2 ± 0.0595
Confidence intervalThe formula for calculating the confidence interval is expressed as:
[tex]CI = z \sqrt{\frac{p(1-p)}{n} }[/tex]
z is the z-score for 99%CI = 2.58p = x/n = 60/300p = 0.2Get the confidence interval
CI = 0.2 ± 2.58*√0.2(1-0.2)/300
CI = 0.2 ± 2.58√0.0005333
CI = 0.2 ± 0.0595
Hence the 99% confidence interval of the population proportion is 0.2 ± 0.0595

On San Martin Boulevard, embedded sensors kept track of the vehicle traffic count each hour for five weekdays, Monday through Friday, between 6 a.m. and 8 p.m. (5 weeks × 14 hours = 70 observations).
The question is incomplete. The complete question is below.
On San Martin Boulevard, embedded sensors kept track of the vehicle trafffic count each hour for five weekdays, Monday through Friday between 6am and 8pm. (5 weeks x 14 hours = 70 observations)
(a) Visually estimate the quartiles Q1, Q2, Q3.
(b) Estimate xmin and xmax.
(c) Is the distribution symmetric?
Answer: (a) Q1 = 3300; Q2 = 3900; Q3 = 4300
(b) xmin = 2400; xmax = 4800
(c) No
Explanation: The figure below shows a box-and-whisker plot: it is a graphical representation of the variation of data observed through quartiles and lines extending from the lowest and to the highest values.
Quartiles divides a list of numbers into 4 parts (quarters). There are 3 important quartiles:
Q1: the lower quartile. Represents the left edge of the box;Q2: the middle (median) quartile. Corresponds to the median of the set of numbers;Q3: the higher quartile. Represents the right edge of the box;The boxplot also have its minimum and maximum, which is given by the lines (whiskers) of the plot.
Analysing the plot for the San Martin Boulevard:
(a) The lower quartile or Q1 is: Q1 ≈ 3300
The median quartile (Q2) is: Q2 ≈ 3900
The higher quartile (Q3) is: Q3 ≈ 4300
(b) The minimum value the data can assume is: xmin = 2400, while the maximum value is: xmax = 4800
(c) No, the distribution is not symmetric because Q2 is not in the middle of the box and the whisker to the left is longer than to the right. A boxplot is symmetric when median is located in the middle of the box and the whiskers are about the same side on both sides.

Katie hikes 5 miles north, 7 miles east, and
then 3 miles north again. What number of
miles, measured in a straight line, is Katie
from her starting point?
(A) 83
(B) 10
(C) 113
(D) 13
Answer:
B is the closest answer
Explanation:
It helps to draw it out to visualize on a grid. But to save time, she ends up traveling a total of 8 miles north and 7 miles east. These are the two legs of the right triangle. You are looking for the straight line she is from her starting point which is the hypotenuse. Use the Pythagorean Theorem, a^2+b^2=c^2
7^2+8^2=c^2
c= 10.63
