Answer:
The number of expected people at the concert is 8,500 people
Step-by-step explanation:
In this question, we are asked to determine the expected number of people that will attend a concert if we are given the probabilities that it will rain and it will not rain.
We proceed as follows;
The probability that it will rain is 30% or 0:3
The probability that it will not rain would be 1 -0.3 = 0.7
Now, we proceed to calculate the number of people that will attend by multiplying the probabilities by the expected number of people when it rains and when it does not rain.
Mathematically this is;
Number of expected guests = (probability of not raining * number of expected guests when it does not rain) + (probability of raining * number of expected guests when it rains)
Let’s plug values;
Number of expected guests = (0.3 * 5,000) + (0.7 * 10,000) = 1,500 + 7,000 = 8,500 people
Answer:
The equation of Line is y = - 8x + 7
Step-by-step explanation:
Given as :
The slop of line is - 8
And The y intercept is 7
As the equation of line is y = mx + c
For y intercept , x = 0
So, With y intercept and slop ,
7 = (-8)× (0)+ c
Or, c = 7
So the equation of line is
y = mx + c
I.e y = ( - 8 ) x + 7
Hence The equation of Line is y = - 8x + 7 Answer
Answer: Multiplying 3x and -x we obtain A= -3x^2
Answer:
you will get more money if he gives you 1 cent per day then doubles it
Step-by-step explanation:
if your brother gives you 25 cents per day, at the end of 10 days you will have $2.50
if he gives you 1 cent per day then doubles it, this will be your daily earnings:
day 1- 0.01
day 2- 0.02
day 3- 0.04
day 4- 0.08
day 5- 0.16
day 6- 0.32
day 7- 0.64
day 8- 1.28
day 9- 2.56
day 10- 5.12
then when you add all of this up, you would recieve 10.23 cents at the end of day 10
100 goes into 1,000 ten times. The answer is 10.
