what is the probability that a red or green marble will be selected from a bag containing 9 red marbles, 7 green marbles, and 11

SVEN [57.7K]

P(red) = 9/(9 + 7 + 11) = 9/27 = 1/3
P(green) = 7/27

P(red or green) = 1/3 + 7/27 = 16/27

Indicate a general rule for the nh term of this sequence.<br> 12a, 15a, 18a, 21a, 24a,...

adelina 88 [10]

Answer:

The general rule for the nth term of this sequence will be:

$a_n=3na+9a$

Step-by-step explanation:

Given the sequence

12a, 15a, 18a, 21a, 24a,...

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

Here,

a₁ = 12a

computing the differences of all the adjacent terms

d = 15a-12a = 3a, d = 18a-15a=3a, d=21a-18a=3a, d=24a-21a=3a

using the nth term formula

$a_n=a_1+\left(n-1\right)d$

substituting a₁ = 12a, d = 3a

$a_n=12a+\left(n-1\right)3a$

$=12a+3na-3a$

$=3na+9a$

Therefore, the general rule for the nth term of this sequence will be:

$a_n=3na+9a$

Answer:

∠y = 70º, ∠z = 60º, ∠w = 70º

Step-by-step explanation:

i believe the angle measures are the same for both triangles.

so ∠z = 60º, ∠x = 50º

to get ∠w, 180 - (50 + 60) = 70

∠w = 70º

∠w and ∠y would be equivalent

louis and valentina have 60 toys to build louis builds 1/2of the toys while valentina builds 2/5 how many toys are left

vodka [1.7K]

Answer:

Step-by-step explanation:

1/2 = 0.5

2/5 = 0.4

60 × 0.5 = 30

60 × 0.4 = 24

30 + 24 = 54

60 - 54 = <u>6</u>
