Answer:
x = 25.
Step-by-step explanation:
Since the longer side of the smallest triangle bisects the largest triangle's right angle, all three triangles shown are similar.
As seen in the diagram, the smaller triangle's hypotenuse (15) corresponds to the the largest triangle's hypotenuse (x), and the smaller triangle's shorter side length (9) corresponds to the largest triangle's shorter side length (15). So, we can set up a proportion...
9 * x = 15 * 15
9x = 225
x = 225/9
x = 25
Hope this helps!
A. The circumference of a circle is the diameter times 3.14 aka pie and for instance, if you have two circles, circle A has a radius of 2 and diameter of 4 and circle B has a radius of 4 and diameter of 8, then if you compare the radius to the diameter (2/4 and 4/8) you get 1/2 for both and you know the circles are similar
x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24
Answer:
REQUIRED TEST STATICS IS 35.19
Step-by-step explanation:
total size of sample = 10,000
men women
voted 2777 3466
did not vote 1444 2313
By chi square test we can find the relationship between gender and participation in the election
<em>
</em>
where
a represent = 2777, b = 3466, c= 1444, d = 2313, N = 10000
Putting values to get chis square statics
<em>
</em>
<em>
</em>
HENCE REQUIRED TEST STATICS IS 35.19
What you would need to do is divide by pi
