A person's blood glucose level and diabetes are closely related. let x be a random variable measured in milligrams of glucose pe
fenix001 [56]
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

5x + 3y = 26<br> 6x + 7y = 21
Serjik [45]
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. :)

Rewrite as a quotient of two base - 9 logarithms. write your answer in simplest form log 17 =<br>​
4vir4ik [10]

Answer:

\frac{log_{9}17 }{log_{9}10 }

Step-by-step explanation:

Using the change of base rule for logarithms

log_{b} x = \frac{log_{c}x }{log_{c}b } ( where c is the new base )

Given

log 17 , that is log_{10} 17 , then

log_{10} 17 = \frac{log_{9}17 }{log_{9}10 }
