The number of arrangements is an illustration of permutations.

The number of arrangement is 5040

The given parameter is:

<em />n = 7<em> --- number of days</em>

<em />r = 7<em> --dinners for 7 days</em>

<em />

So, the number of different arrangement is

^nP_r = \frac{n!}{(n - r)!}

Substitute known values

^7P_7 = \frac{7!}{(7 - 7)!}

^7P_7 = \frac{7!}{0!}

^7P_7 = \frac{5040}{1}

^7P_7 = 5040

Hence, the number of arrangement is 5040

What are the measures of &lt; 1 and &lt; 2. Show your work or explain your answer.
VashaNatasha [74]

Answer:

m<1 = 105°

m<2 = 75°

Step-by-step explanation:

Since lines c and d are parallel to each other, therefore:

m<2 = 75° (corresponding angles are congruent)

m<1 + m<2 = 180° (linear angle pair)

Substitute

m<1 + 75° = 180°

Subtract 75 from both sides

m<1 = 180° - 75°

m<1 = 105°

In a class of 42 students, 18 students are in the Math Club, 5 students
natta225 [31]

Answer:

15 maybe?

Step-by-step explanation:

42 - 14 = 28

18 - 5 = 13

28 - 13 = 15

subtract the 14 because it says it is in neither.

Subtract 5 from 18 because 18 are in math and only 5 are in both math and science.

Subtract 13 from the 28 because those 13 are in math and wont be in science also.
