The National Institute for Clinical Excellence (NICE) recommends that a target blood glucose level for non-diabetic people should be 5.0 mmol/L. A random sample of 35 adults was taken from a rural community in Texas, to determine if the county health officials should offer special pre-diabetic services for the community. In taking the sample the average glucose level of the participants was 5.29 mmol/L, with a standard deviation of 1.18 mmol/L. Calculate the t-statistic for this test. Use a t-critical of 2.03.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph

this "question" looks more like a project is there any other info you can give me about this. it could be too complex for someone else to do on this website
