Mr. Demerly wants to find out what his 23 Calculus students are doing for Spring break. Six of the girls are going to the Beach/Lake. Five of the boys are staying home and so are 4 of the girls. Two kids total are going to the mountains. There are only 10 girls in Mr. Demerly’s Calculus class.

How many boys are going to the Beach/Lake?
Is this a joint or a marginal frequency?

How many students are going to the Mountains?
Is this a joint or a marginal frequency?

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
