I hope this helps you
Euclid
h^2=4.6
h=2 square root of 6
h^2+6^2=base^2
24+36=base^2
base=2square root of 15
h^2+4^2=height^2
24+16=height^2
height=2 square root of 10
My answer is a and c becuase they equal the same on each side
So you can you the Pythagorean theorem to solve this problem.
if each side of the square is a certain length x, then the square is made up of two right triangles.
the sides adjacent to the right angle are length x while the hypoteneus is the diagonal whcih measures 36 feet.
a^2 + b^2 = c^2
x^2 + x^2 = 36^2
2x^2 = 1296
x^2 = 648
x = 25.456
area of a square = x^2 = 648 ft^2
Answer:
0.4 , 0.1
Step-by-step explanation:
Let number of boys be = b , number of girls = b + 4 . As total students = 20 b + b + 4 = 20 → 2b + 4 = 20 → 2b = 20 - 4 = 16 → b = 16 / 2 = 8 (boys) , so girls = 12
Prob (a random first child is a boy) = boys / total students = 8 c 1 / 20 c1, or = 8 / 20 = 0.4
Prob ( a 'Tina' out of two Tina is the last) = 2 c 1 / 20 c 1 , or = 2 / 20 = 0.1
Answer:
Step-by-step explanation:
From the given information;
The null hypothesis & alternative hypothesis:
The test statistics can be computed as:
The p-value = 2(Z > 2.11) since this is a two-tailed test
The p-value = 2( 1 - Z < 2.11)
The p-value = 2 (1 -0.9826)
The p-value = 2 (0.0174)
The p-value = 0.0348
Decision Rule: To reject the 
if the p-value is less than
Conclusion: We fail to reject and conclude that the population mean = 2, thus the machine is properly adjusted.
