Let x be the number of adults (under 50 years old) after a 12-hour fast where X ~ N(85,25)
The problem is missing some parts but here are the answers:
(a) x is more than 60
z(60) = (60-85)/25 = -1
P(x > 60) = P(z > -1) = 0.158655
(b) x is less than 110
z(110) = (110-85)/25 = 1
P(x < 110) = P(z < 1) = 0.841345
So, look. It sorta depends on what the question is asking. Since I only have the equations, and not the question, I'll do my best.
Right, so, if you wanna know the slope and everything, the first equation
<span>5x + 3y = 26 the slope and everything for it, it:
</span><span>Slope = -3.333/2.000 = -1.667
x-intercept = 26/5 = 5.20000<span>
y-intercept = 26/3 = 8.66667
And the second one </span></span>6x + 7y = 21:
<span>Slope = -1.714/2.000 = -0.857
x-intercept = 21/6 = 7/2 = 3.50000<span>
y-intercept = 21/7 = 3
Now, theres also where you just wanna find "x" and "y". Tell me which one you need to know. :)

Answer:
Step-by-step explanation:
Using the change of base rule for logarithms
x = 
( where c is the new base )
Given
log 17 , that is 
17 , then
17 =
Im not sure how to put the sign here but x= long division sign 3+5, negative sign in front of long division sign 3+5
