The length of life of an instrument produced by a machine has a normal distribution with a mean of 12 months and standard deviat
Vikentia [17]

Answer:

solved

Step-by-step explanation:

Mean = 12

SD = 2

Answer to part 2)  Less than 7 months

P(x < 7)

P(x < 7) = P(z < (7-12)/2) = P(z < -2.5)

This probability can be obtained by referring to the Z table

Thus P(x < 7) = 0.0062

1) Between 7 and 12 months

P(7 < x < 12) = P( x< 12) - P(x < 7)

We have P(x < 12) = 0 ......[because mean = 12]

and P(x < 7) = 0.0062 ...[this we got is part a]

Thus on plugging these values we get

P( 7 < x < 12) = 0.5 - 0.0062 = 0.4938

Thus P(7 < x < 12) = 0.4938

Can someone please help with these volume equations? 10th grade geometry. will reward brainly
prisoha [69]

Answer:

First picture - 20.42 m

Second picture - 12.9 m

Step-by-step explanation:

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

V=b^2\frac{h}3

Where,

b = base - 3.5 m

h = height - 5 m

Thus,

V=3.5^2\frac{5}{3}

20.41667m^3 ≈ 20.42m^3

------------------------------------------------------------------------------------------------------------

Formula for pyramid:

V=b^2\frac{h}3

Where,

b = base - 3 m

h = height - 4.3 m

Thus,

V = 3^2\frac{4.3}{3}

12.9m^3
