Answer:

m-s+0.50

3m+2s=23.95

Step-by-step explanation:

the first one is defining m in terms of S

the second is solving

I know they didn't ask but here is the solution:

so in this case you would replace 3m with 3(s+0.50)

Suppose compact fluorescent light bulbs last, on average, 11,500 hours. The distribution is normal and the standard deviation is
juin [17]

Answer:

2.275%

Step-by-step explanation:

The first thing to do here is to calculate the z-score

Mathematically;

z-score = (x-mean)/SD

from the question, x = 12,300 hours , mean = 11,500 hours while Standard deviation(SD) = 400 hours

Plugging the values we have;

z-score = (12,300-11,500)/400 = 800/400 = 2

Now, we want to calculate P(z ≤ 2)

This is so because we are calculating within a particular value

To calculate this, we use the z-score table.

Mathematically;

P(z ≤ 2) = 1 - P(z > 2) = 1 - 0.97725 = 0.02275

To percentage = 2.275%

Math picture below...
SashulF [63]

Answer:

Step-by-step explanation:

ans is c) f(x) is a polynominal function. The degree is 5 and the leading coefficient is -7.

x -> ∞, f(x) -> ∞; x -> -∞, f(x) -> -∞

the only ans that follows the above is a) f(x)=7x^9-3x^2-6

correct statments are:  c)  (1, 6.08) and (3, 0.75) are local extrema for the function and  d)  (-2, -9.67) is the global minimum for the function.
