[4H-16] A bottle of orange juice is being filled by machine. Amount dispensed by the machine is known to be approximately normal
Assoli18 [71]

Answer:1.5625

Step-by-step explanation:

Given

mean \mu =10 ounces

standard deviation \sigma =m ounces

For bottles to be filled over 12 ounces i.e. area right to the bell curve for z score

and area left  side of the z score is 1-0.1=0.9

so value close to 0.9 in standard normal curve which is  0.8997

z score corresponding to 0.8997 is 1.28

also z score for 12 ounce

z=\frac{x-\mu }{\sigma }

z=\frac{12-10}{m}

1.28=\frac{2}{m}

m=\frac{2}{1.28}

m=1.5625

1. The position of a particle moving along a coordinate axis is given by: s(t) = t^2 - 5t + 1. a) Find the speed of the particle
zimovet [89]

Answer: \left |  2t-5\right |,\ 2,\ 2t-5

Step-by-step explanation:

Given

Position of the particle moving along the coordinate axis is given by

s(t)=t^2-5t+1

Speed of the particle is given by

\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=\left |  2t-5\right |

Acceleration of the particle is

\Rightarrow a=\dfrac{dv}{dt}\\\\\Rightarrow a=2

velocity can be negative, but speed cannot

\Rightarrow v=\dfrac{ds}{dt}\\\\\Rightarrow v=\dfrac{d(t^2-5t+1)}{dt}\\\\\Rightarrow v=2t-5

PLZ HELP! 20 POINTS!
agasfer [191]

Answer:

a) The error is that, the initial value is n=1 NOT n=3

b) The sum is a_n=a_{n+1}+5=192

c)The explicit formula is  a_n=5n+3

The recursive formula is a_n=a_{n+1}+5,

Step-by-step explanation:

The given arithmetic series is  8 + 13 + ... + 43.

The first term is a_1=8, the  common difference is d=13-8=5

The nth term is given by:

a_n=a_1+d(n-1)

We substitute the values to get:

a_n=8+5(n-1)\\a_n=8+5n-5\\\\a_n=3+5n

To find how many terms are in the sequence we solve the equation:

3+5n=43\\\implies 5n=43-3\\5n=40\\n=8

The summation notation is  \sum_{n=1}^8(3+5n)

The error the student made is in the initial value.

It should be n=1 NOT n=3

b) The sum of the arithmetic series is calculated using:

S_n=\frac{n}{2}(a+l)

We substitute o get:

S_8=\frac{8}{2}(5+43)

S_8=4(48)

S_8=192

c) The explicit formula we already calculated in a), which is a_n=3+5n

The recursive formula is given as:

a_n=a_{n+1}+d

We substitute d=5 to get:

a_n=a_{n+1}+5
