Hello, I have done this same math question before.
1. 15 dollars
2. Deposit=15*month+105
3. Deposit=15*12+105=$285
4. 500=15*month+105
395=15*month
26.33=month
Round up to 27 for the nearest whole month, so month 27.
Hope this helps!
Answer:
Step-by-step explanation:
- p = 15 + 6ln (5q+4)
- p = 15 + 6ln (5*5800 + 4)
- p = 15 + 61.68
- p = $76.68
The formula for finding the surface area of a sphere is A=4π

. Since we already have the radius, we just plug that into the equation, like so:
A = 4 x 3.14 x 
First, following the rules of PEMDAS, do the exponent, coming out with an answer of 1. Now, multiply 4 x 3.14, which is 12.56. 12.56 x 1 = 12.56.
Rounded to the nearest tenth, your answer is
12.6.
Hope this helps!
Answer:
[ 5.456, 5.544]
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 5.5 ounces
Standard deviation r = 0.2 ounces
Number of samples n = 80
Confidence interval = 95%
z value (at 95% confidence) = 1.96
Substituting the values we have;
5.5+/-1.96(0.2/√80)
5.5+/-1.96(0.022360679774)
5.5+/-0.043826932358
5.5+/-0.044
= ( 5.456, 5.544) ounces
Therefore the 95% confidence interval (a,b) = ( 5.456, 5.544) ounces
