Answer:
mean is 5
Step-by-step explanation:
<h2>
MEAN</h2>
mean is regarded as the average number of items
<h3>mean formula:</h3>
<em>(sum of terms) / (number of terms)</em>
<h3><u /></h3><h3><u>Firstly</u></h3>
the numbers in the data set are :
3,3,3,4,6,6,7,8
they are already arranged in order, so no need to rearrange.
<h3><u>Next </u></h3>
add the numbers together to find the total :
3 +3 +3 +4 +6+ 6+7 +8
= 40
ALSO,
find how many number of terms they are --- this is 8
Last
use the mean formula to solve :
<em>(sum of terms) / (number of terms)</em>
= 40/8
= 5
<h3><em>
<u>the mean is the 5 </u></em></h3>
Area and perimeter are in the ratio of 1:3. but if u mean to ask about the ratio of perimeters & areas of both triangles. the answer would be 1:1
8) So remember the sum of all angles inside a triangle is equal to 180°. We first want to figure out the angle below the 110°.
A straight line is 180° so if we do 180 - 110 we get 70° therefore the angle below the 110° is 70°.
So we now know two angles in the triangle, 70° and 80°. Add these and we get 150°. Now we can determine the final angle (the one labelled (2x - 6)) which will be 30°.
So let’s make it into an equation:
2x - 6 = 30
Add 6 to both sides to isolate 2x:
2x = 36
Divide by 2 to get the value of x:
x = 18
10) Since the sum of all angles in a triangle is 180, and there are only 3 angles, we can determine A easily.
B = 10°
C = 160°
So to determine A:
180 - 160 - 10
Which gives us 10
Therefore A = 10°.
So the answers:
8) x = 18
9) A = 10°
I hope this helps you!!
It's important to know that rigid transformations don't change the size or shape, this means the corresponding angles between the image and preimage are congruent. Due to the reflection transformation, angle C corresponds to angle Z.
<h2>Therefore, the answer is angle Z.</h2>
Question 7: $3945
78,900÷100×5= 3,945
or 789,00×0.05= $3,945
Question 8: I think it may be $675.46 ( but I'm not sure)
$1010 is her annual insurance premium so to find one month we need to divide $1010 by 12
$1010÷12= $84.20
also her annual real estate tax is $938 and to find one month we need to divide this by 12 as well.
$938÷12=$78.20
and in order to find out her combined monthly payment we need to add them all together
$513.12+$84.16+$78.16= $675.46
Question 9: is False
Question 10: I don't know
Hope this helps
