Answer:
Step-by-step explanation:
(1+25 /100) (1-20/100) (1-50/100) <1
5/4 x 4/5 x 1/2 <1
Decrease in volume (in percent)
(1+25 /100) (1-20/100) (1-50/100) x 100
=48.8%

Exponential functions are known to increase geometrically. An example of exponential function is p(x) = 500(1.02)^x
<h3>Exponential functions</h3>
Exponential functions are known to increase geometrically. The standard exponential function is given as:
y = ab^x
a is the base
x is the exponent
From the given options, the function written in this form is
p(x) = 500(1.02)^x. Hence an example of exponential function is
p(x) = 500(1.02)^x

Answer:
2.39 x 10^5 miles
Step-by-step explanation:
Although it is not usually written, there is always a .0 at the end of a number unless there is a specific decimal that was given.
So, the number here is 239,000.0 and if you count the number of spaces that the decimal needs to move in order to be in the correct spot for scientific notation (which is always after the first number), there is 5 spaces.
Therefore the answer is 2.39 x 10^5 miles.
Answer: They would have to score an 88%
Step-by-step explanation:
1.) The mean of 84, 92, 83, and 78 is 337
2.) 337 divided by 4 is 84.25%
3.) If you add 88 to 337 and divide by 5, you get 85%
