Answer:
It will take 47 hours
Step-by-step explanation:
We can have the exponential function as follows;
P = I( 1 + r)^n
if the initial value was x , the final will be 2x
The change rate is 1.5% , which is r, this is same as;
1.5/100 = 0.015
So what we want to calculate is the n attached
This will be;
2x = x ( 1 + 0.015)^n
2 = 1.015^n
ln 2 = n ln 1.015
n = ln 2/ln 1.015
n = 46.55
This is approximately 47 hours
The true equation will be f(6) = 0. Then the correct option is C.
<h3>What is a function?</h3>
A statement, principle, or policy that creates the link between two variables is known as a function.
The function f(x) is given by the set of ordered pairs.
{(1,0), (–10,2), (0,6), (3,17), (–2,–1)}
Then the function can be written as
f(abscissa) = ordinate
Then the function will be
f(0) = 6
Then the correct option is C.

Answer:
Options B,C and E are correct choices.
Step-by-step explanation:
We are asked to find correct answers for the given box and whisker plots.
Let us our options one by one.
A. This option is false as lowest value for children's cereals is 30 and highest value for adults is 35.
B. This option is correct. We can see our upper value for combined range will be 60 and lower value will be 5 and range is upper value- lower value.

C. Since we know that we can find spread of data by its range.


So option C is correct indeed.
D. This options is false because for adults mean and median are different while for children mean and median are same.
E. We can see that median for children's cereals is 45 and it is about 12 for adults.
We can see that
. So median amount of sugar in children's cereals is 3 times as much as the median amount of sugar in adult's cereals.
Therefore, options B,C and E are correct choices.
If four times the sum of a number and 5 is divided by 3, the result is 16. Step 1. Let x be the number.
Step 2. Four times the number and 5 is divided by 3
Step 3. The result is 16
Step 4. Multiply by 3 to both sides of equation to get rid of denominator
Step 5. Subtract 20 from both sides of equation
Step 6. Divide by 4 to both sides of equation
Step 7 ANSWER is x=7.
I hope the above steps were helpful.
