Hi!

The 18 passes to the other side dividing.

18 t = 72

t = 72 / 18

t = 4

Hope this helps, good studies! :)

Ramil and Carly collected the honey from 4 of his beehives. From the first hive collected 1/3 gallons of honey. The last hives y

BaLLatris [955]

Answer:

We know that:

First hive gave 1/3 gallon.
The other three hives gave 1/4 gallon each.

To find the total gallons of honey, we just have to sum all of it.

$H=\frac{1}{3}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}\\H=\frac{1}{3}+3\frac{1}{4}\\H=\frac{1}{3}+\frac{3}{4}\\H=\frac{4+9}{12}=\frac{13}{12}$

As a mixed number:

$\frac{13}{12}=1\frac{1}{12}$

Therefore, Carly collected 1 and 1/12 gallons. Or, 1.08 gallons in total.

Archie is stranded in a war zone in the land of the Xhosas. His only chance of survival is to reach Sudland, which lies 100 mile

LenaWriter [7]

Answer:

The chances of success for Archie is $P(S|D) = 35\%$

Step-by-step explanation:

From the question we are told that

The distance of Sudland from Xhosas is d = 100 miles

The probability of failure is $P(F) = 0.26$

The probability of choosing the desert route is $P(D) = \frac{1}{40} = 0.025$

The probability of reaching Sudland through the mountain is $P(S|M) =0.75$

Generally the probability of choosing the mountains route is

$P(M) = 1 - P(D)$

$P(M) = 1 - 0.025$

$P(M) = 0.975$

Generally the probability of success is mathematically represented as

$P(S) = 1- P(F)$

$P(S) = 1- 0.26$

$P(S) = 0.74$

Generally the probability of success in reaching Sudland is also mathematically represented as

$P(S) = P(S|M) * P(M) + P(S|D) * P(D)$

=> $P(S|D) = \frac{P(S) - P(S|M) * P(M)}{P(D)}$

substituting values

=> $P(S|D) = \frac{0.74 - 0.75 * 0.975}{0.025}$

=> $P(S|D) = 0.35$

=> $P(S|D) = 35\%$

In a group of 60 students, 15 liked maths only, 20 liked science only and 5 did not liked any of two subjects. How many of them

evablogger [386]

Answer:

Step-by-step explanation:

Given

n (A) = 15

n (B) = 20

Students who do not like any subject = 5

Hence, number of students who would like either both or either of the two subjects = 60-5 = 55

n (A or B) = n (A) + n (B) - n (A and B)

Number of students linking both the subjects

55 - 15-20

= 55-35 = 20

Number of students linking only one subject = 60-20-5 = 35
