To solve this we use the z statistic. The formula for z
score is:
z = (x – u) / s
where x is the sample value = less than 16, u is the
sample mean = 16.1, s is standard dev = 0.1
z = (16 – 16.1) / 0.1
z = - 1
From the standard distribution tables at z = - 1,
P (z = -1) = 0.1587
<span>So about 15.87% is underweight.</span>
The answer should be D. 2x plus 3x is 5x. -6+9 is +3.
Answer:
-3, 5/2
Step-by-step explanation:
What are the roots of the function y = 4x2 + 2x – 30?
To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.
Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)
Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)
Use the zero product property and set each factor equal to zero and solve.
x+3=0 2x-5 = 0
x = -3, 5/2
The roots of the function are -3, 5/2.
Hope this helped!
Running = 2/3
Swimming = 5/6
5/6 - 2/3 = 5/6 - 4/6 = 1/6
Answer : She spent 1/6 hour longer swimming than running.
Answer: yes because they both go to the 0 and has the same shape.
Step-by-step explanation: yes
