Step-by-step explanation:

Well, 3/5 hours equals 30 secs.This means that he started 3:30 hours ago .To find out what time was it you have to subtract 3:30 from the finishing time. So, 10:18-3:30=6:48.If you have any further questions please contact me.

What is the solution to 2/3 x + 5 =1

geniusboy [140]

Answer:

x = -6

Step-by-step explanation:

The solution means to solve for x. To solve for "x", isolate the variable. This means to separate it from everything else. Do this using reverse operations in reverse BEDMAS order.

2/3 x + 5 = 1

2/3 x + 5 - 5 = 1 - 5 Subtract 5 from both sides

2/3 x = -4

(2/3 x) / (2/3) = (-4) / (2/3) Divide both sides by 2/3

x = (-4) / (2/3)

x = -6 Solution

In circle D, if the measure of arc Gec is 230 , what is the measure of minor arc GFC

BabaBlast [244]

Answer:

The measure of minor arc GFC is $130\°$

Step-by-step explanation:

we know that

In a circle the sum of the major arc plus the minor arc is equal to 360 degrees

see the attached figure to better understand the problem

Let

x------> the major arc GEC

y-----> the minor arc GFC

so

$x+y=360\°$

we have

$x=230\°$

substitute in the equation and solve for y

$230\°+y=360\°$

$y=360\°-230\°=130\°$

The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the proba

zlopas [31]

Answer:

The probability that there are 8 occurrences in ten minutes is

option B. 0 .0771

Step-by-step explanation:

Given:

Random Variable = x

Mean number of occurrences in ten minutes is 5.3.

The probability of an occurrence is the same in any two time periods of an equal length

To Find:

The probability that there are 8 occurrences in ten minutes = ?

Solution:

Let X be the number of occurrences of the event X

$X \sim {Pois} (\lambda)$

$\lambda = E(X) = 5.3$

Possion of distribution is given by ,

$P(X=x) = \frac{e^{- \lambda} \lambda^{x}}{x!}$

Substituting the values,

$P(X=8) = \frac{e^{- 5.3} 5.3^{8}}{8!}$

$P(X=8) = \frac{(0.004994) ( 622596.904)}{40320}$

$P(X=8) = \frac{(3109.24894)}{40320}$

P(X=8) = 0.0771
