Answer:
z-score for 900 points = -4
Step-by-step explanation:
To find the z scores
z=(x-mean)/standard deviation
so
z=(900-1500)/150
z= -600/150
Answer:
Width = 4.85 feet
Length = 7.85 feet
Step-by-step explanation:
Given:
Perimeter of a rectangle = 25 2/5 ft = 25.4 feet
Length = 3 + Width
Computation:
Assume;
Width = a
So,
Length = 3 + a
Perimeter of a rectangle = 2(l + b)
25.4 = 2[(3 + a) + a]
25.4 = 2[3 + 2a]
25.4 = 6 + 4a
4a = 19.4
a = 4.85
Width = 4.85 feet
Length = 3 + 4.85
Length = 7.85 feet
Answer:
False
Step-by-step explanation:
This is false. We can disprove this by plugging in the number into the function f(x) = lnx
f(0) = ln0
Since
,
This is not 0 so f(0) cannot be equal to 0, thus disproving the statement.
Answer:
A
Step-by-step explanation:
because it's subtracting the xaxis by -2 so subtracting it will cause the linear equations to shift left by 2 untis
Answer:
The required distance is 147 m.
Step-by-step explanation:
Consider the provided information.
Renee and Mike are skateboarding the ratio of the distance that Renee boards to the distance Mike boards 5 to 3
This can be written as:

It is given that Renee boards 245 m.
Substitute the respective values in the above equation.




Hence, the required distance is 147 m.
