Answer:
Standard Form is also known as Scientific Notation or Exponential Notation, is a ... Step 2 : ⇒ To convert standard form into number, multiply the coefficient with a ... To find the scientific notation count the number of places to the number from the ... are 3 places, therefore we write 45000 in standard notation as: 4.5 x 104.
Step-by-step explanation:
Answer:
a) 0.194
b) $440.8
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $9.40
Standard Deviation, σ = $4.40
Formula:
Standard error due to sampling =
a) P(tips from 40 parties > $400)
Thus, the average pay is
P(x > 10)
Calculation the value from standard normal z table, we have,
b) We have to find the value of x such that the probability is 0.01
Calculation the value from standard normal z table, we have,
Thus, the mean tip is $11.02
Tip for 40 parties =
Thus, he earns $440.8 on the best 1% of such weekends.

Answer:</h3>
5.51 seconds
<h3>
Step-by-step explanation:</h3>
y = 0 when the stone hits the ground. At that point, t can be found from ...
... 0 = -16t^2 +486
... 0 = t^2 -30.375 . . . . divide by -16
... 30.375 = t^2 . . . . . . add the opposite of the constant
Take the square root to get ...
... √30.375 = t ≈ 5.51 . . . . seconds
Remember
translates to
so
translates to
remember, if a^b=c^b when b=b, then a=c
and x^-m=1/(x^m)
hmm
32=x⁵
5th root both sides
2=x
x=2
Answer:
V=65.94 in^3 (inches cubed)
Step-by-step explanation:
V=πr^2h/3
h = 7
r = 3
V = (3.14)(3^2)(7/3)
V= (3.14)(9)(2.333)
V=65.94 in^3
