Compute and compare the values of the sample mean and median.
By how much could the largest sample observation be decreased without affecting the value of the median?
Answer:
[tex]Mean = 1.030[/tex]
[tex]Median = 1.009[/tex]
[tex]Difference = 0.141[/tex]
Step-by-step explanation:
Given
Data:
.736, .863, .865, .913
.915, .937, .983, 1.007
1.011, 1.064, 1.109, 1.132
1.140, 1.153, 1.253, 1.394
Solving (a): Mean and Median
Mean
Mean is calculated as thus;
Mean = Summation of observation divided by number of observations[tex]Mean = \frac{.736 +.863 +.865 +.913 +.915 +.937 +.983 +1.007 +1.011 +1.064 +1.109 +1.132 +1.140 +1.153 +1.253 +1.394}{16}[/tex]
[tex]Mean = \frac{16.475}{16}[/tex]
[tex]Mean = 1.0296875[/tex]
[tex]Mean = 1.030[/tex] Approximated
Median
Since the number of observation is 16;
[tex]Median = \frac{16 + 1}{2}[/tex]
[tex]Median = \frac{17}{2}[/tex]
Median = 8.5th item
This can be determined by calculating the average of the 8th and 9th item
[tex]Median = \frac{1}{2}(1.007 + 1.011)[/tex]
[tex]Median = \frac{1}{2}(2.018)[/tex]
[tex]Median = 1.009[/tex]
Solving b:
For the median to remain 1.009, the largest sample (1.394) must be greater than or equal to 1.253
Calculating the difference:
[tex]Difference = 1.394 - 1.253[/tex]
[tex]Difference = 0.141[/tex]
Hence, it can be reduced by 0.141

.If m∠ ROT = 155, what are m ∠ ROS and m∠TOS?
Can someone explain how to do it also?
Answer:
ROS=72° TOS=83°
Step-by-step explanation:
(4x-20)+(3x+14)=155
7x-6=155
7x=161
x=23
4(23)-20=72
3(23)+14=83
Answer:
ROS is 72 degrees.
TOS is 83 degrees.
Step-by-step explanation:
So we know that the measure of Angle ROT is 155.
Angle ROT is the combined value of Angle ROS and Angle TOS. In other words:
[tex]ROT=ROS+TOS[/tex]
Substitute 155 for ROT, (4x-20) for ROS, and (3x+14) for TOS. Thus:
[tex]155=(4x-20)+(3x+14)[/tex]
Combine like terms:
[tex]155=(4x+3x)+(-20+14)[/tex]
Add:
[tex]155=7x-6[/tex]
Add 6 to both sides:
[tex]161=7x[/tex]
Divide both sides by 7:
[tex]x=23[/tex]
So, the value of x is 23.
Now, plug that into each of the Angle equations to solve for each angle:
[tex]ROS=4x-20\\ROS=4(23)-20[/tex]
Multiply:
[tex]ROS=92-20[/tex]
Subtract:
[tex]ROS=72[/tex]
Same thing for TOS:
[tex]TOS=3x+14\\TOS=3(23)+14[/tex]
Multiply:
[tex]TOS=69+14[/tex]
Add:
[tex]TOS=83[/tex]
And we're done!

Write the equation for the line that passes through (-5, -4) and (3, 12)
Answer:
I believe it is y=2x+6.
Answer:
[tex]y=2\,x+6[/tex]
Step-by-step explanation:
Start by finding the slope of the segment that joins the two given points, using the slope formula:
[tex]slope=\frac{y_2-y_1}{x_2-x_1} =\frac{12-(-4)}{3-(-5)} =\frac{16}{8} =2[/tex]
Now, you can write the general equation of the line in slope-intercept form as:
[tex]y=m\,x+b\\y=2\,x+b[/tex]
and find the line's y-intercept (b) by using either one of the given points - for example (3, 12):
[tex]y=2\,x+b\\12=2\,(3)+b\\12=6+b\\b=6[/tex]
Therefore, the equation of the line is:
[tex]y=2\,x+6[/tex]
The percentage of U.S. college freshmen claiming no religious affiliation has risen in recent decades. The bar graph shows the
percentage of first-year college students claiming no religious affiliation for four selected years from 1980 through 2012
a. Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation. Round the
percentage to the nearest tenth.
b. Estimate the percentage of first-year college females who will claim no religious affiliation in 2030,
Answer:
0.5%/year
24.2%
Step-by-step explanation:
Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation
Percentage of females by year:
1980 = 6.2%
1990 = 10.8%
2000 = 13.6%
2012 = 21.7%
Average yearly increase :
Percentage increase between 1980 - 2012 :
2012% - 1980% = ( 21.7% - 6.2%) = 15.5% increase over [(2012 - 1980)] = 32 years
15.5 % / 32 years = 0.484375% / year = 0.5%/year
b. Estimate the percentage of first-year college females who will claim no religious affiliation in 2030,
Given an average increase of 0.484375% / year
(2030 - 1980) = 50 years
Hence by 2030 ; ( 50 years × 0.484375%/year) = 24.218% will claim no religious affiliation.
=24.2% (nearest tenth)
In this exercise we have to use the percentage knowledge to calculate an estimate per year, in this way we find that;
A) [tex]0.5\%/year[/tex]
B) [tex]24.2\%[/tex]
Estimate the average yearly increase in the percentage of first-year college females claiming no religious affiliation. Percentage of females by year:
[tex]1980 = 6.2\%\\1990 = 10.8\%\\2000 = 13.6\%\\2012 = 21.7\%[/tex]
A) Average yearly increase can be caculeted by:
[tex]2012\% - 1980\% = ( 21.7\% - 6.2\%) = 15.5\% = 32 years \\15.5 \% / 32 years = 0.484375\% / year = 0.5\%/year\\[/tex]
B) Estimate the portion of first-old age institution of higher education woman the one will claim no religious association with an organization fashionable 2030, Given an average increase of:
[tex](2030 - 1980) = 50 years\\ ( 50 years * 0.484375\%/year) = 24.2\%[/tex]

What percent is equivalent to 3/10? A.) 0.3% B.) 3% C.) 10% D.) 30%
Answer: 0.3
Step-by-step explanation:
A percent that is equivalent to 3/10 is: D.) 30%.
What is a percentage?In Mathematics, a percentage is any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.
By multiplying both the numerator and denominator by a common number such as 10, we have the following:
3/10 × 10/10
30/100
30%
Based on the information provided, we can logically deduce that 30% is equivalent to 3/10. Therefore, the correct answer option is: D.) 30%.

The flanagans are having their fifth child. All of their childern are athletically gifted,so the youngest child is bound to be athletically gifted as well. Is this a deductive argument or inductive?
Answer: inductive argument.
Step-by-step explanation:
Deductive argument is a logical argument in which a conclusion is made upon the given premises which are assumed to be true.
inductive argument works on the basis of a series of observation and then bring it to frame a certain conclusion.
Here, Flanagans are considering the observation they made by previous children (i.e. they are athletically gifted) and applying the same on the new one by saying "youngest child is bound to be athletically gifted as well.".
So it is of-course an inductive argument.

Ashley has 9 pizzas .She is serving each person at a party 3/4 of a pizza.How many can she serve at the party?
Answer:
Ashley can serve 12 pieces of pizza in the party
Step-by-step explanation:
To solve this question we need to convert the 9 pizzas to decimal:
9 times 4 = 36. That is:
9 pizzas are equal to 36/4 of pizza (36/4 = 9)
As Ashley is serving 3/4 of a pizza she can serve:
36/4 ÷ 3/4 = 36/3 = 12
Ashley can serve 12 pieces of pizza in the partyComplete the answer. 8 is 1/10 of

2 tons is what percent of 206 tons?
Answer:
0.971%
Step-by-step explanation:
A percentage is simply a ratio to a whole. If we assume 206 tons to be the whole, we can say this:
2 tons / 206 tons == 0.00971
And the percentage is out of 100 so:
0.00971 * 100 == 0.971 %
Hence, 2 tons is 0.971% of 206 tons.

The point (2,6) lies on the graph of the equation y = kx^2 - 3x Find the value of K
Answer:
k = 3Step-by-step explanation:
y = kx² - 3x
Since the points lie on the graph we can substitute the values of x and y that's
( 2 ,6) into the equation to find k.
We have
6 = (2)²k - 3(2)
6 = 4k - 6
4k = 6 + 6
4k = 12
Divide both sides by k
That's
[tex] \frac{4k}{4} = \frac{12}{4} [/tex]
We have the final answer as
k = 3Hope this helps you
