<h3>
Answer: 1.21</h3>
Work Shown:
z = (x - mu)/sigma
z = (72.4 - 69.0)/(2.8)
z = (3.4)/(2.8)
z = 1.2142857 .... which is approximate
z = 1.21
Answer:
Step-by-step explanation:
a.11/12 =11 is numerator and 12 is denominator
b.7/512 =75 is numerator and 512 is denominator
c.12/10 = 12 is numerator and 10 is denominator
d0/78 = 0 is numerator and 78 is denominator
point to remember : In fraction,upper part is always numerator and down part is denominator.
Answer:
Step-by-step explanation:
we know that
Any right triangle, must satisfy the Pythagorean Theorem
so
where
c is the hypotenuse (greater side)
a and b are the legs (perpendicular sides)
substitute the given values
Answer:
The answer is A. 48°
Step-by-step explanation:
Since triangle JKL and triangle PQR are equal, so their angles are equal too.
∠P = ∠J - 52°
∠Q = ∠K - 48°
∠R = ∠L - 80°
