Answer:
a. P= 0.6364
b. P = 0.3636
c. Q = $21.25
d. P = 0.5
Step-by-step explanation:
given data
value of a stock varies = $13 to $24
solution
P (stock value is more than $17)
P = 
P = 
P = 0.6364
and
P (value of the stock is between $17 and $21)
P = 
P = 
P = 0.3636
and
Let the upper quartile be Q


(24 - Q) = 2.75
so
Q = $21.25
and
P(X > 20 | X > 16)
P = 
P = 
P = 0.5
Answer:
No, it is not prime.
Step-by-step explanation:
67^2 = 4489
A number cannot be prime if it is divisible by a number besides 1 and itself. 4489 is divisible by 67; no perfect square can be prime.
The correct answer is $70
Answer:
The cost of 4 medium pizzas:
4 (x - 3)
Step-by-step explanation:
#3
x = the cost of a large pizza
medium pizza costs $3 less than a large pizza. So it's x - 3
If 4 medium pizzas then it will be: 4 (x - 3)
Answer:
or 6.32
Step-by-step explanation:
We can find the distance between two points by using this formula

where the x and y values are derived from the given points
The points given are ( -2 , 5 ) and ( 4 , 3 )
So we plug in the x and y values of those coordinates into the distance formula

or 6.32
