Answer:
92,960,000
Step-by-step explanation:
When multiplying by 10 to the power of something. You can just add move the decimal point "n" times to the right. (where n is the exponent over 10)
For example:
1.23456 * 
= 123.456 (the decimal point moved <u>2</u> steps to the right)
4 * 
= 40000 (the decimal point moved <u>4</u> steps to the right)

Answer:
7 + 28d
Step-by-step explanation:
-7(-1 - 4d) [ -7 gets multiplied with -1 and-4d when brackets open ]
= -7 × (-1) -7 × (-4d)
= <u>7 + 28d (Ans)</u>
Answer: 1
Step-by-step explanation:
If n/4 = 2, then n = 8
Answer:
Step-by-step explanation:
Part 1
P(z < -1.45)
Using the z score table
P =
Part 2
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
a) P(X >52)
x = 52
Mean = 60
Standard deviation = 8
z = 52 - 60/8
z = -1
P-value from Z-Table:
P(x<52) = 0.15866
P(x>52) = 1 - P(x<52) = 0.84134
b) P(48 < x < 64)
