Answer:
let's see what to do buddy....
Step-by-step explanation:
The mean of the 10 values denoted x equals 7.4
So we have :
[tex] \frac{x(1) + x(2) + x(3) + ... + x(10)}{10} = 7.4 \\ [/tex]
Multiply the sides of the equation by 10 :
[tex]10 \times \frac{x(1) + x(2) + x(3) + ... + x(10)}{10} = 7.4 \times 10 \\ [/tex]
After do that we have :
[tex]x(1) + x(2) + x(3) + ... + x(10) = 74 \\ [/tex]
Which means we have the sum of all values.
And we're done...
Thanks for watching.

3x + 21 6x - 60 find the two angles measure from the diagram answers 78,102 78,78 or 102,102
Answer:
102 and 102Step-by-step explanation:
There is no diagram attached
It is assumed the angles are vertical
Vertical angles are congruent as per vertical angles theorem
3x + 21 = 6x - 606x - 3x = 21 + 603x = 81x = 81/3x = 27Angle measures
3*27 + 21 =81 + 21 = 102So the answer is
102 and 102Use the diagram to complete the statement.
Answer:
∠FJH ≅ ∠BJA
Step-by-step explanation:
From the given image, we notice that the only congruent relation ∠FJH has is with ∠BJA.
Where ∠BJA is vertically opposite to ∠FJH
Hence, we can say that ∠FJH ≅ ∠BJA since both these angles are vertically opposite
In the figure below, ABC is similar to XYZ . What is the length of ZX ? Enter only the number as an integer or decimal. An image shows two similar right triangles, A B C and X Y Z. Triangle A B C is smaller than triangle X Y Z. In triangle A B C, side A B is 2, side B C is 4, and side C A is 3. In triangle X Y Z, side X Y is 7, side Y Z is 14, and side Z X is labeled N.
Given:
Triangle ABC is similar to triangle XYZ.
In triangle ABC AB=2, BC=4, CA=3.
In triangle XYZ, XY=7, YZ=14, ZX=N.
To find:
The length of ZX.
Solution:
If two triangles are similar, then their corresponding sides are proportional.
Since [tex]\Delta ABC\sim \Delta XYZ[/tex], therefore
[tex]\dfrac{AB}{XY}=\dfrac{BC}{YZ}=\dfrac{CA}{ZX}[/tex]
[tex]\dfrac{2}{7}=\dfrac{4}{14}=\dfrac{3}{N}[/tex]
[tex]\dfrac{2}{7}=\dfrac{2}{7}=\dfrac{3}{N}[/tex]
[tex]\dfrac{2}{7}=\dfrac{3}{N}[/tex]
On cross multiplication, we get
[tex]2\times N=3\times 7[/tex]
[tex]2N=21[/tex]
Divide both sides by 2.
[tex]N=\dfrac{21}{2}[/tex]
[tex]N=10.5[/tex]
Therefore, the length of side ZX is 10.5 units.

Answers:
Point A = 0.62Point B = 7/9Point C = 10/9===================================================
Explanation:
Using a calculator, we get the following decimal approximations
1/3 = 0.3332/3 = 0.6677/9 = 0.77810/9 = 1.111Based on that, we see that 0.620 is between 0.333 and 0.667
We can say 0.333 < 0.620 < 0.667
which is the same as 1/3 < 0.62 < 2/3
So, 0.62 is between 1/3 and 2/3
0.62 will be placed at point A.
--------------
Since 7/9 = 0.778 is between 2/3 = 0.667 and 1, this means,
7/9 will go to point B.
--------------
Since 1.111 > 1, this means 10/9 > 1
Therefore 10/9 will go to point C
