Answer:

97

Step-by-step explanation:

For this equation we have to plug in, so z= 6 and w=7. the question is 8z+7w

so plug in 6 for z and 7 for w. 8(6)+7(7) so 8*6 is 48 and 7*7= 49. 48+49= 97

hope this helps :)

Suppose that the useful life of a car battery, measured in months, decays with parameter 0.03 . We are interested in the life of
scZoUnD [109]

Answer:

a) X ~ e(0.03)

b) μ = 100/3

c) \sigma = 100/3

d) A battery is expected to last 100/3 months (33 months and 10 days approximately).

e) For seven batteries, i would expect them to last 700/3 months (approximately 19 years, 5 months and 10 days).

Step-by-step explanation:

a) The life of a battery is usually modeled with an exponential distribution X ~ e(0.03)

b) The mean of X is μ = 1/0.03 = 100/3

c) The standard deviation is \sigma = 1/0.03 = 100/3

d) The expected value of the bateery life is equal to its mean, hence it is 100/3 months.

e) The expected value of 7 (independent) batteries is the sum of the expected values of each one, hence it is 7*100/3 = 700/3 months.

13. y =<br> -x2 + 12x - 5<br> Axis of symmetry (aos):
marissa [1.9K]

Answer:

Slope = 24.000/2.000 = 12.000

When y = 0 the value of x is 5/-12 the line therefore crosses the x axis at x=-0.41667

x-intercept = 5/-12  = -0.41667
