P(z < x) = 0.6064 - 0.5 = 0.1064
From the normal distribution table
P(z < 0.27) = 0.1064
Therefore the z-score is 0.27
I can't explain it very well for you, sorry.
Answer:
45\
Step-by-step explanation:
The answer is the second image from left to right (B). Examples of direct and inverse variations are showed in the image below. :)
<span>Let x be length of shorter leg
</span>4cm longer than the shorter leg<span> x + 4 = length of longer leg
</span>hypotenuse is 8 cm longer than the shorter <span>
x + 8 = </span>length of <span> hypotenuse
</span>
phytagorus rule
<span>x^2 + (x+4)^2 = (x+8)^2
x^2 + x^2 +8 x + 4^2 = x^2 + 16x + 8^2
x^2 - 8x - 48 =0
(x + 4 ) (x - 12) - 0
x= - 4 we reject negative number
so x= 12
