A football field is 160 ft wide. Convert the width to yards

A compound experiment consists of drawing at random twice without replacing from a jar with 3 red, 3 white, and 2 black marbles.

Eddi Din [679]

The solution to your problem about the probability of getting first a red and then a black marble is as follows:

(3 red / 8 total) * (2 black / 7 total) = 3/28

Therefore, the probability of getting first a red and then a black marble is 3/28.

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

Wyatt offers 8 types of sandwiches and 4 types of tacos. He will increase his selection of sandwiches by 1 per month. He will in

Klio2033 [76]

Answer:

In 4 months Wyatt offer an equal number of sandwiches and tacos.

Step-by-step explanation:

We are given the following in the question:

Types of sandwiches = 8

Rate of increase of sandwich = 1 per month

Thus, number of sandwiches in x months will be given by

$n_1(x) = 8 + x$

Types of tacos = 4

Rate of increase of tacos sandwich = 2 per month

Thus, number of tacos in x months will be given by

$n_2(x) = 4 + 2x$

Equating the two equations, we get,

$n_1(x) = n_2(x)\\8 + x = 4 + 2x\\\Rightarrow x = 4$

Thus, in 4 months Wyatt offer an equal number of sandwiches and tacos.
