Answer:
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The figure shows a kite
The kite has two pairs of consecutive and congruent sides and the diagonals are perpendicular
That means
TS=VS
TQ=VQ
TR=RV
we have
so
solve for x
<em>Find the value of RV</em>
substitute the value of x
Remember that
---> by segment addition postulate
we have
so
3m-10=2(4m-5)
3m-10=8m-10
3m-8m=-10+10
-5m=0
m=0
Answer:
circle question: 69.66
the other question: 66.8
Step-by-step explanation:
For the circle question:
the circle is inscribed in the square, so the diameter of the circle = side of the square
so we need to find the area of square and circle
then do this
square area - circle area
square area(side×side) = 324
circle area(pi×r^2)≈254.469
so shaded region = 69.66
__________
the other question:
we need to find the area of triangle and the area of the rectangle and add them together
A of Triangle (1/2×base×hight) = 34.32
A of rectangle (width × length) = 31.92
add them, so the answer will be = 66.8
The z-score of the data can be calculated by the formula expressed as follows:
z = ( score - mean ) / standard deviation
z = (126 - 150 ) / 11 = <span>-2.18
</span>
A z-Score<span> is a statistical </span>measurement<span> of a </span>score's<span> relationship to the mean in a group of </span>scores<span>. A </span>Z-score<span> of 0 means the </span>score<span> is the same as the mean.</span><span>
</span>
Answer:
Mean absolute deviation. The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset
