Answer:
55.1
Step-by-step explanation:
50% of 95 is 47.5
8% of 95 is 7.6
95-47.5+7.6
To solve this, we need to use the z statistic. The formula for z score is:
z = (x – u) / s
where x is sample value = less than 90, u is the sample mean = 90.6, s is the standard deviation = 17.2
z = (90 – 90.6) / 17.2
z = -0.035
From the standard distribution tables:
P (z = -0.035) = 0.4860
Therefore there is about 48.60 % chance that it will be less than 90 pounds
Distance = Square Root ((X2 - X1)^2<span> + (Y2 - Y1)^</span>2<span>)
</span>Distance = Square Root [ (11 --13)^2 + (2 -9)^2 ]Distance = Square Root [ 24^2 + -7^2 ]Distance = Square Root [ 576 + 49 ]Distance = Square Root [ 625 ]Distance = 25

The fraction is a cubic root, so to rationalize the denominator, you would multiply them by 3.
The answer is b. 3
For this, I'll be using the substitution method. Since y = 1/3x - 6, replace the y variable in the first equation with 1/3x - 6 and solve for x:
Now that we have the value of x, plug it into either equation to solve for y:
<h3><u>In short, the solution to this equation is (3,-5).</u></h3>
