A jar of peanut butter contains 454 g with a standard deviation of 10.2 g. Find the probability that a jar contains more than 46
Fofino [41]

Answer:

The probability that a jar contains more than 466 g is 0.119.

Step-by-step explanation:

We are given that a jar of peanut butter contains a mean of 454 g with a standard deviation of 10.2 g.

Let X = <u><em>Amount of peanut butter in a jar</em></u>

The z-score probability distribution for the normal distribution is given by;

                                Z  =  \frac{X-\mu}{\sigma}  ~ N(0,1)

where, \mu = population mean = 454 g

           \sigma = standard deviation = 10.2 g

So, X ~ Normal(\mu=454 , \sigma^{2} = 10.2^{2})

Now, the probability that a jar contains more than 466 g is given by = P(X > 466 g)

            P(X > 466 g) = P( \frac{X-\mu}{\sigma} > \frac{466-454}{10.2} ) = P(Z > 1.18) = 1 - P(Z \leq 1.18)

                                                                  = 1 - 0.881 = <u>0.119</u>

The above probability is calculated by looking at the value of x = 1.18 in the z table which has an area of 0.881.

kirill [66]
Answer: 30 pairs of shorts

21x+420=35x
subtract 21x from both sides of the equation.
420=14x
get rid of the x by division
420/14
you get 30 =x

almond37 [142]

Answer:

12 games

Step-by-step explanation:

Let x be the number of games played

The y won 75% of the games played and that was 9

x * 75% = 9

Change to decimal form

x * .75 = 9

Divide each side by .75

x * .75 /.75 = 9/.75

x =12

They played 12 games

The school had 366 chairs and 12 classrooms. How many chairs could they put in each classroom?
Assoli18 [71]

Step-by-step explanation:

Divide 366 by 12 for your answer.

366/12=30.5

You can't place half a chair, so round down for 30 chairs per classroom.
