Are right triangles always congruent

1 answer:

6 0

All right triangles have two legs, which may or may not be congruent. The legs of a right triangle meet at a right angle. The other side of the triangle (that does not form any part of the right angle), is called the hypotenuse of the right triangle.

PLEASE HELP! Slope parallel to line y = 2x/3 + 4 PLZ!

marta [7]

Answer:

2/3

Step-by-step explanation:

I think you meant y=2/3x+4 because what you wrote is not the right way to right that equation, but anyways the slope of the parallel line is 2/3 because lines that are parallel have the same slope.

The Z-score is based on the concept of the normal distribution, the fact that we can expect 95% of the values in the distributio

Dennis_Churaev [7]

Answer:

C.) In perfect health.

Step-by-step explanation:

Given an average weight of 15kg and a standard deviation of 3kg for children of 4 years. Since the weight is based on a normal Z - distribution of 95% which is mean ± 2(standard deviations)

Mean weight interval is :

15 - 2(3) ; 15 + 2(3)

(9 ; 21) ; this weight interval could be interpreted to mean the normal or perfect weight value.

Therefore, given that the child weighs 12kg

Since, 12 kg falls within in the interval, we can conclude that the child is in perfect health.
