Answer:
a) Figure attached
b) For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:
Step-by-step explanation:
For this case we define the random variable X= depth (in centimeters) of the bioturbation layer in sediment for a certain region, and we know the distribution for X, given by:
Part a
For this case we can see the figure attached.
Part b
For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:
Answer:
8x6=48 so in 6 hours she will have enough money to buy it
Step-by-step explanation:
6 hours will give her 48 dollars if the dvd costs 45 so she will have to work 6 hours
<span>difference of squares formula:
</span>a^2<span> – b^</span>2<span> = (a + b)(a – b)
</span>so answers are
<span>(3 + xz)(–3 + xz)
</span><span>(y2 – xy)(y2 + xy)
</span><span>(64y2 + x2)(–x2 + 64y2)
</span><span>
cause
</span><span>(3 + xz)(–3 + xz)
= </span><span>(xz + 3 )(xz - 3)
= x^2z^2 - 9
--------------
</span>(y^2 – xy)(y^2 + xy)
= y^4 -x^2y^2
----------
<span>(64y^2 + x^2)(–x2 + 64y^2)
=</span>(64y^2 + x2)(64 - x^2)<span>
= 64^2 y^4 - x^4</span>
The answer is D. A translation does not change a figure's size or shape because each of its points are moved the same amount and in the same direction(s).
(X)+2(x+1)=26
3x=24
X=8
Y=x+1
Y=8+1
Y=9
The two numbers are 8 and 9
