There are 42 students on a large bus and the rest are on a smaller bus. If 40% of the students are on the smaller bus how many t

Liono4ka [1.6K]

Answer:

There are 70 students on the two buses, 42 on the large and 28 on the smaller.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of students on the large bus = 42

Number of students on the small bus = 40% of the students

2. How many total students are on the two buses?

For answering the question, we will use the Rule of Three Simple, this way:

42 students are 60% of total students, how much students are the 100%?

Total students = 42 * 100/60

Total students = 4,200/60 = 70

There are 70 students on the two buses, 42 on the large and 28 on the smaller.

Given the following formula, solve for t. v = u + at

levacccp [35]

Answer:

t=(v-u)/a

Step-by-step explanation:

The equation we start with is v=u+at and we need to isolate t.

First subtract u from both sides

v-u=at

Now just divide both sides by a

(v-u)/a=t or t=(v-u)/a

When a man observed a sobriety checkpoint conducted by a police department, he saw 671671 drivers were screened and 77 were arr

kifflom [539]

Answer:

$P(\overline W)=0.98957$

Step-by-step explanation:

Number of drivers Screened = 671

Number Arrested for Driving While Intoxicating = 7

If the W denotes the event of screening a driver and getting someone who is intoxicated.

The Probability of W, $P(W)=\frac{7}{671}=0.01043$

The Probability $P(\overline W)$ is the probability of the event of screening a driver and getting someone who is not intoxicated. Simply put, it is the Probability of the Complement of W.

From Probability Theorem,

$P(W)+P(\overline W)=1\\Since \: P(W)=0.01043\\0.01043+P(\overline W)=1\\P(\overline W)=1-0.01043\\=0.98957$
