Question 8 of 10
Sliva [168]

Answer:

y = (-3/7)x + 2

Step-by-step explanation:

slope-intercept form is y = mx + b, where m = slope and b = y-intercept.

all you need to do is plug the values into the equation! :)

since your slope is (-3/7), plug that in for m.

y = mx + b ⇒ y = (-3/7)x + b

and since your y-intercept is 2, plug that in for b.

y = (-3/7)x + b ⇒ y = (-3/7)x + 2

therefore, the line's equation in slope-intercept form is y = (-3/7)x + 2.

<em>don't worry about the parentheses, i only put them in there to separate the 7 in -3/7 from x. i'm not good at putting equations in here on brainly lol i just wanted to make sure you didn't think that it was -3 over 7x.</em>

<em />

i hope this helps! have a lovely day <3

Suppose that the TSH (Thyroid Stimulating Hormone) levels among healthy individuals are normally distributed with a mean of 3.1
arlik [135]

Answer:

std deviation = 1.641

Step-by-step explanation:

Given that the TSH (Thyroid Stimulating Hormone) levels among healthy individuals are normally distributed with a mean of 3.1 units/mL.

If X represents the TSH then X is N(3.1, sigma)

We do not know sigma value, but we are given that exactly 95% of healthy individuals have TSH levels below 5.8 units/mL.

We know as per standard normal distribution score that 95th percentile referes to Z score of 1.645

Using this we can find standard dev

5.8 = 3.1+1.645*standard dev\\Standard dev = \frac{5.8-3.1}{1.645} \\=1.641
