Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .
<u>Step-by-step explanation:</u>
We are given that there is a 23% chance it will rain on any day, we need to find what is the probability that it will rain on the first day and be clear (not rain ) on the next two days . Let's do it step by step:
Probability for first day is to rain i.e.
.
Probability for second day is to not rain i.e.
.
Probability for third day is to not rain i.e.
.
Now, Probability for occurrence of these 3 events simultaneously is :
⇒ ![(0.23)(0.77)(0.77)](https://tex.z-dn.net/?f=%280.23%29%280.77%29%280.77%29)
⇒ ![(0.23)(0.5929)](https://tex.z-dn.net/?f=%280.23%29%280.5929%29)
⇒ ![0.1719](https://tex.z-dn.net/?f=0.1719)
∴ Probability that it will rain on the first day and be clear (not rain ) on the next two days is 0.1719 .
Answer:
straight angle
Step-by-step explanation:
I know that angle one and angle two will add to give 180 degrees as it lies on a straight line hence the answer would be straight angle
Answer:
3x^5 - 4x^4 - 5x^3 + x^2 + 11x - 6
Answer:
y=5
x=7
Step-by-step explanation:
When given an expression in the form a⁻ᵇ the expression is the same as 1/aᵇ where a and b are integers.
Solving the question by giving the equivalents of the expression:
Therefore (-j)⁻⁷ is the same as 1/j⁷
The value of x=7
k⁻⁵+m⁻¹⁰=1/k⁵+1/m¹⁰
Therefore the value of y is 5.
Answer:
m = 1.25d
Step-by-step explanation:
A train is traveling at a constant speed and goes a distance of 7 ½ kilometers or 7.5 km in 6 minutes.
6 min = 7.5 km
1 min = (7.5/6) km/min
= 1.25 km/min
or
In m min, (7.5/6)d is travelled by the train. Hence, the relation between d and is :
![m=\dfrac{7.5d}{6}\\\\m = 1.25d](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B7.5d%7D%7B6%7D%5C%5C%5C%5Cm%20%3D%201.25d)
Hence, this is the required solution.
