Answer:

5C1 (9C3) (5C3)

And replacing we got:

\frac{5!}{1! 4!} (\frac{9!}{3! (9-3)!}) (\frac{5!}{3! (5-3)!}) = 5*84*10=4200

So then we have a total of 4200 possibilities in order to have a veggle wrap

Step-by-step explanation:

For this case we can use the combinatory formula given by:

nCx= \frac{n!}{x! (n-x)!}

And for this case we have a total of 9 vegatables and 5 condiments and 5 types of tortilla. Then the total number of possibilities are:

5C1 (9C3) (5C3)

And replacing we got:

\frac{5!}{1! 4!} (\frac{9!}{3! (9-3)!}) (\frac{5!}{3! (5-3)!}) = 5*84*10=4200

So then we have a total of 4200 possibilities in order to have a veggle wrap

Hi could someone explain this?? <br><br>im thinking it is J=50(15)^t??? ​
Lapatulllka [165]

Answer:

J=15t+50

Step-by-step explanation:

The equation to represent this situation will be in the form J=mt+b where b is the starting value of love units, m represents the "love units" that are multiplied by the number of week, t is the number of weeks, and J represents Jack's love at that specific week.

The equation becomes: J=15t+50

To check, the equation should equal 50 when t=0, 65 when t=1, and 80 when t=2.

Checking t=0:

J=15(0)+50=0+50=50

Checking t=1:

J=15(1)+50=15+50=65

Checking t=2:

J=15(2)+50=30+50=80

The equation J=15t+50 does model the behavior of Jack's love at any week t based on the given data. Note that the equation used was based on slope intercept form (y=mx+b) due to the given data having a linear relationship.

lara31 [8.8K]

Answer:

f=\frac{9c}{5}+32

Step-by-step explanation:

c=\frac{5\left(f-32\right)}{9}

Switch sides:

\frac{5\left(f-32\right)}{9}=c

Multiply both sides by 9:

\frac{9\times5\left(f-32\right)}{9}=9c

5\left(f-32\right)=9c

Divide both sides by 5:

\frac{5\left(f-32\right)}{5}=\frac{9c}{5}

f-32=\frac{9c}{5}

Add 32 to both sides:

f-32+32=\frac{9c}{5}+32

f=\frac{9c}{5}+32

A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of st
Alekssandra [29.7K]

Answer:

2676 students

Step-by-step explanation:

Total number of students =. 40,140

During study:

Sample size = 210

Number of samples who speak 3 or more languages = 14

Proportion who speak 3 or more languages :

14 / 210 = 0.0666666

Applying the proportion to the total. Population :

0.0666666 * total number of students

0.0666666 * 40140

= 2675.997324

= approximately 2676 students
