Answer:
23%
Step-by-step explanation:
$1,771 divided by $ 2,300 = 77%
100% - 77% = 23%
I’m pretty sure This rounds to 900
Answer:
- a) P(x) = 32000*1.04^x
- b) $37435
- c) During year 7
Step-by-step explanation:
<u>Given</u>
- Initial pay = $32000
- Increase rate = 4%
a. <u>Formula</u>
b. Year 5 is after 4 years, so we are looking for the value of P(4)
- P(4) = $32000*1.04^4 = $37435
c. <u>P(x) = 40000, x = ?</u>
- 40000 = 32000*1.04^x
- 1.04^x = 40000/32000
- 1.04^x = 1.25
- log 1.04^x = log 1.25
- x = log 1.25 / log 1.04
- x = 5.69, this is 6 years after
The required number of the years is 6 + 1 = 7
Answer:4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let x be the normal body temperature
X is N(99, sigma)
Sample mean x bar = 98.2 and s = 0.63
Margin of error = Z critical * 0.63 = 1.95 *0.63 = 1.2285
It is safe since 1.5 <1.96 critical value of z at 95%
