Answer:
58.73%
Step-by-step explanation:
What we must do is calculate the z value for each value and thus find what percentage each represents and the subtraction would be the percentage between those two values.
We have that z is equal to:
z = (x - m) / (sd)
x is the value to evaluate, m the mean, sd the standard deviation
So for 2400 we have:
z = (2400 - 2488) / (250)
z = -0.35
and this value represents 0.3632
for 89 we have:
z = (2900 - 2488) / (250)
z = 1.65
and this value represents 0.9505
we subtract:
0.9505 - 0.3632 = 0.5873
Therefore the probability would be 58.73%
ΔJKL, sin(JLK)=JK/KL=3/6=0.5
<JKL=30deg.
cos(JLK)=JL/KL
JL=KL*cos(JLK)=6cos(30deg.)
<JLK + <JLM = <MLK
30 + <JLM = 61
<JLM=31deg
in ΔMJL
tan(JLM)=JM/JL
JM=JL*tan(JLM)
=6cos(30deg.)*tan(31deg)
=3.12
yes, the data suggest an association between age and experiencing side effects.
In children no side effects are greater than adults.
In other words, adults experienced side effects than children. The answer is c.
Find the area of the triangles and smal ler square and add them together ; and find the area of the complete square and set them equal to each other (these are known truths)
triangle: l×w /2
square: s^2
There are 4 triangles so
4 (1/2ab)+c^2= (a+b)(a+b)
simplify
2ab+c^2= a^2+2ab+b^2
-2ab both sides
c^2=a^2+b^2
tada!! it's proven :)
