From the looks of it, each ticket costs $ 12...and there is a fixed rate of 150
ur equation would be : y = 12x + 150....where x is the number of students and y is the total cost...but that is an equation, and u want an expression...so I guess the expression would be 12x + 150
the cost of each ticket (12) multiplied by the number of students (x), added to 150 will give u the total cost
Answer:
Step-by-step explanation:
So we have the expression:
To simplify, we can use the product of a power property, where:
So, our expression will be equal to:
Let's evaluate 3⁶, which equates to:
For our x, we can use the power of a power property, where:
So, our expression is:
Evaluate:
And we're done!
First you need to figure out the slope:
y2-y1/x2-x1=(1+5)/(-5-7)=-1/2
y+5=-1/2(x-7)
y=-1/2x-3/2
Answer:
a
b
c
d
Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158 is greater than 3( Note :the probability of z-score = 3 is 97%)
e
The correct option is option 3
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.25
The sample size is n = 508
Generally the mean is mathematically represented as
=>
=>
Generally the standard deviation is mathematically represented as
=>
=>
Generally the z-score of 158 is mathematically represented as
=>
=>
Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158 is greater than 3( Note :the probability of z-score = 3 is 97%)
What this means is that the almost the whole professional hockey league player are born in the first month which is unusual
