Answer:
d) 330
Step-by-step explanation:
The number of ways can a dance instructor send 4 of her 11 students to summer dance program is C(11 , 4)
That is ways
by using formula
now simplification
=
after cancelling 7! and on simplification
=
after cancellation we get 330 ways
The number of ways can a dance instructor send 4 of her 11 students to summer dance program is 330
Answer:
Marissa = 28 cakes in 2 weeks
Carlos = 60 cakes in 20 days
Shelby = 5 cakes in 2 days
To compare, make sure that the variables are of equal value
Marissa = 28 cakes in 14 days
Carlos = 60 cakes in 20 days
Shelby = 5 cakes in 2 days
How many cakes does each of them bake in a day?
Marissa = 28 ÷ 14
= 2 cakes/day
Carlos = 60 ÷ 20
= 3 cakes/day
Shelby = 5 ÷ 2
= 2.5 cakes/day
Carlos has the steepest graph. This is because he has the largest number of cakes made per day compared to Marissa and Shelby.
19 yards divided by 2.5 minutes.
=19/2.5
= 7.6 yards/minute
0.75m + 5 = 0.5m + 9
0.75m - 0.5m = 9 - 5
0.25m = 4
m = 4 / 0.25
m = 16 <=== at 16 miles, the companies will charge the same amount
The period will change coefficient of x by 2 pi / pi/2 = 4
and the vertical shift will add 3 so its
sin 4x + 3
Hope this helps
