Given:
Felix's total credit card balance is described by the following function
[tex]f(p)=p(1.30)[/tex]
To find:
The total bill plus interest if Felix owes 2500.
Solution:
We have,
[tex]f(p)=p(1.30)[/tex]
Where [tex]p[/tex] is the amount Felix owes.
Putting [tex]p=2500[/tex] in the given function, we get
[tex]f(2500)=2500(1.30)[/tex]
[tex]f(2500)=3250[/tex]
Therefore, the total bill plus interest is 3250.

Scott drinks 6 cups of water a day. How many fluid ounces of water does Scott drink? (2 points)
Group of answer choices
36 fluid ounces
48 fluid ounces
52 fluid ounces
68 fluid ounces if your right I give u a lot of points
There are 48 fluid ounces of water Scott drink.
Define the term ounces?An ounce is a unit of measurement of weight or mass in both the US customary system and the British imperial system. In the US customary system, one fluid ounce of water weighs about 1.04 ounces (oz).
Each day, Scott consumes 48 fluid ounces of water.
To convert cups to fluid ounces, we need to multiply the number of cups by 8 (as there are 8 fluid ounces in one cup).
So, 6 cups of water is equal to:
6 cups × 8 fluid ounces per cup = 48 fluid ounces
Therefore, there are 48 fluid ounces of water Scott drink.

Answer:
x = 6.7
Step-by-step explanation:
We know that 3.5 + x = 10.2, so if we do inverse operations we can find out the value of x.
10.2 - 3.5 = 6.7
we can check our work by substituing it back in the equation for x
6.7 + 3.5 = 10.2
so now we know that x = 6.7. I hope this helps :)
Answer: x=6.7
Step-by-step explanation:
x+3.5=10.2

Gary: [tex]6>0.5t[/tex]
Nancy: [tex]30 -t \le 18[/tex]
Jamal: [tex]12 \le t+12[/tex]

Which of the inequalities is/are true
Gary: [tex]6>0.5t[/tex]

Divide both sides by 0.5

Answer:
1) -3/2
Step-by-step explanation:
The common ratio is the amount you multiply by to get to the next number in the sequence. To calculate this you will need to divide the term by its preceding term.
For example (3/4) / (-1/2)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (3/4) x (-2/1) = -3/2
Check this by doing the next term (-9/8) / (3/4)
When dividing by fractions you should apply KCF (Keep Change Flip), so you will end up with (-9/8) x (4/3) = -3/2

The quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2
Answer:
D
Step-by-step explanation:
hope it helps u
The statement is the quotient of 32 and 4 added to the product of fraction 1 over 2 and 16, then subtract 2 describes the expression 32 ÷ 4 + (1/2 x 16) - 2.
The given expression is "32 ÷ 4 + (1/2 x 16) - 2".
"32 ÷ 4" is the division of 32 by 4, which results in the quotient of 8. So, the first part of the expression simplifies to 8.
"(1/2 x 16)" is the product of the fraction 1/2 and 16.
Multiplying these values gives us 8.
Now, we have "8 + 8 - 2". Adding 8 and 8 gives us 16.
Subtracting 2 from 16 results in a final value of 14.
Therefore, the expression "32 ÷ 4 + (1/2 x 16) - 2" simplifies to 14.

Answer:
The rocket's maximum height will be 1424 feet.
It will reach that height in 4 seconds.
It will reach the ground in 8 seconds.
Step-by-step explanation:
One easy way to find the peak is to find the derivative and solve for zero:
h(t) = -16t² + 128t + 1680
To find the derivative of each term in that format, you simply multiply the coefficient by the exponent, and reduce the exponent by one. In the case of terms with no variable, they disappear. That gives us:
h'(t) = -32t + 128
This derivative describes the rate of change of h with respect to t, so to find the peak, we simply need to solve it for zero:
0 = -32t + 128
32t = 128
t = 4
So the maximum height occurs when t = 4. Let's plug it in to the original equation:
h(t) = -16t² + 128t + 1680
h(4) = -256 + 512 + 1680
h(4) = 1424
So the rocket's maxiumum height is 1424 feet.
And we've already answered the second question, it happens at 4 seconds.
Also, the amount of time going up will be the same as the amount of time going down, which means that it will reach the ground in twice that time, or 8 seconds.

6) The Delphi method used for forecasting: A) uses a single measure that weights multiple indicators and provides a measure of overall expectation. B) obtains forecasts through a comparative analysis with a previous situation. C) uses a panel of experts, whose identities are typically kept confidential from one another, to respond to a sequence of questionnaires. D) uses measures that are believed to influence the behavior of a variable that the researcher wishes to forecast.
Answer:
C) uses a panel of experts, whose identities are typically kept confidential from one another, to respond to a sequence of questionnaires.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Opportunity or convenience sampling.
The Delphi method is a structured communication framework or technique that is typically used as an interactive forecasting method to arrive at a group decision or opinion by relying on the feedback from a panel of experts. The individual opinions of the panel of experts are modified to ensure anonymity and are mainly an unbiased exchange of ideas, so as to produce a convergence of opinions.
Hence, the Delphi method used for forecasting uses a panel of experts, whose identities are typically kept confidential from one another, to respond to a sequence of questionnaires.
