So if you have a right triangle with legs legnth a and b
and a hypotonuse legnth c, then
a^2+b^2=c^2
given in the comments is that
a=15
c=20
input and solve
15^2+b^2=20^2
225+b^2=400
subtract 225 from boths ides
b^2=175
take square root of both sides
b=5√7
We are asked to d<span>etermine the area under the standard normal curve that lies to the left of the following z score of 1.57. in this case, we can use the rules of integration as this is related to area under the curve:
</span><span>1/2+1/π * integral of (</span><span> e</span><span>−z^2 </span><span>d</span>z0 from 0 to x/2 where z=1.5
Answer is 0.8665

3. You should multiplyou of means multiplication 85/100 300/100
The answer is C because Which of the following equations is equivalent to 1/2x-2/3y= c I'd just 6 times as much, so 1/2 times 6 equals 3 and 2/3 times 6 is 4
