Answer:
x = 6
Step-by-step explanation:
Given
6( - 4 ) = 30 ( divide both sides by 6 )
- 4 = 5 ( add 4 to both sides )
= 9 ( multiply both sides by 2 to clear the fraction )
3x = 18 ( divide both sides by 3 )
x = 6
There are 5 hotels. Each of these 3 people will have 5 ways to choose the hotel. By basic principle of counting, the total number of ways to which the hotels can be chosen is equal to ,
5 x 5 x 5
That is, multiplying the number of ways each can choose the hotel. The answer is 125.
If each of them are to stay in different hotels, the first one will have 5 choices. The second will have only 4. Lastly, the third will only have 3 choices. That is,
5 x 4 x 3 = 60
We divide the second answer by the total and multiply by 100% to get the probability.
P = (60/125) x 100%
P = 48%
<em>ANSWER: 48%</em>

The formula of a slope:
We have two points (-6, -8) and (-14, 4).
Substitute
Answer:
P(1833 < X < 1975) = 7.55%
Step-by-step explanation:
From the given information:
Let X be the random variable that obeys a normal distribution and which represents the monthly electric consumption during winter by all households in the Boston area.
X N ( μ = 1650 , σ² = 320² )
The probability that a monthly consumption of 1883 to 1975 kilowatt is given as:
P(1833 < X < 1975) = P(Z< 1.0156) - P(Z< 0.738)
P(1833 < X < 1975) = 0.8452 - 0.7697
P(1833 < X < 1975) = 0.0755
P(1833 < X < 1975) = 7.55%
Answer:
270ft^2
Step-by-step explanation:
we need to multiply the terms given
15feet*18feet
we know feet*feet=
=ft^2
and
15*18=270
finally we have
270
=270ft^2
