3.777... into a mixed number
Hey there! I'm happy to help!
Let's call our fraction x.
x=3.777......
We want to get rid of the repeating stuff. If we multiply our fraction by 10, we get 10x=37.7777.
We see that if we subtract x from 10x, the repeating numbers will be cancelled out. Let's do this.
10x=37.7777
-
x=3.77777
=
9x=34
We divide both sides by 9.
x=34/9=3 7/9.

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 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.

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

what is 12x8 please tell me i need to know :) ")
Answer:
96
Step-by-step explanation:
10 x 8 = 80
2 x 8 = 16
so 80 + 16 = 96 :)
The equivalent value of the equation is A = 96
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be p = 12
Let the second number be q = 8
Now , A = pq
On simplifying the equation , we get
A = 12 x 8
So , the left hand side of the equation is equated to the right hand side by the value of 12 x 8
On multiplying 12 times 8 , we get
A = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8
A = 96
Therefore , the value of A = 96
Hence , the expression is A = 96

.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!
