Answer:

t=312 minutes or t=5.2hrs

Step-by-step explanation:

I.Given that Stephanie has 6 classes a day of 52 minutes each.

-To get the duration spent in class each day, we multiply the total number of classes per day by the duration per class:

t=C_tD_c, C_t=6, D_c=52\\\\t=6\times 52\\\\=312 \ mins

Stephanie spends 312 minutes per day in class

II. Get the duration in Hours:

#We multiply the class duration by number of class then divide by 60 minutes to get total duration in hours:

t=C_tD_c, C_t=6, D_c=52\\\\t=6\times 52\\\\=312 \ mins\times\frac{1\ hr}{60\ min}\\\\=5.2\ hrs

Stephanie spends 5.2hrs per day in class

enot [183]

Answer:

x = 1/3

Step-by-step explanation:

15 = 1/2 + 3/2x + 10

15 - 1/2 -10 = 3/2x

9/2 = 3/2x

9 x 2x = 3 x 2

18x = 6

x = 6/18

x = 1/3

Norma Jean makes $25 per hour. She works 35 hours per week. She gets a commission of 15% on her total sales. How much should Nor
TEA [102]

Answer:

$24166.67

Step-by-step explanation:

$25 per hour and works 35 hours per week

Norma Jean makes 35 * 25  (<em>without sales) = </em>$875

<em> </em>Total commission made by Norma<em> </em>= 4500-875 = $3625

<em>let total number of sales by Norma be x</em>

15% is the same as 15/100

<em>so </em>(15/100) * x =3625 <em> multiplying both sides by 100</em>

15x = 362500<em> making x subject of formula</em>

x = 362500/15

x = 24 166.67

Norma should sell total items worth $24166.67

There are 5 pens in a container on your desk. Among them, 3 will write well but 2 have defective ink cartridges. You will select
Norma-Jean [14]

Answer:

Kindly check explanation

Step-by-step explanation:

Total Number of pens = 5

Number of defective pens = 2

Number of non-defective pens = 3

A.) number of defective pens selected :

X : {0, 1, 2}

It is possible that no defective pen will be selected ; 1 defective will be chosen or both pens are defective.

2.)

Defective as Success (since selecting a defective pen is the point of interest.

3.)

Since selection is done without replacement

Probability of success per selection is different for each selection ;

Number of defective = 2

Number of observations = 5

P(success on first selection) = 2/5

P(success on second selection) = 1/4

Hence, X is not well approximated by a binomial random variable.

4.) if selection is done with replacement ; then then the probability of success per selection will be the Same for each selection made. Hence, X will be well approximated by a binomial Random variable.

5.) If sampling is done without replacement, then the the hypergeometric function will be a more effective approximation.
