Answer:
Step-by-step explanation:
Given that the formula for exponential calculation :
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
A = final amount
P = initial principal balance
r = increasing rate
n = number of times increases applied per time period
t = number of time periods elapsed
[tex]A = 5,000,000,000(1 + \frac{2}{100})^{5}\\A = 5,000,000,000(\frac{100}{100} + \frac{2}{100})^{5}\\A = 5,000,000,000(\frac{102}{100})^{5}\\A = 5,000,000,000(\frac{51}{50})^{5}\\A = 5,000,000,000(1.104)\\\\A = 5,520,000,000\\A = 5.52billion[/tex]

The solution the inequality 3|x+2|<6 is D. -4<x<0 .
What is inequality ?Inequality represents comparing two non equal quantities.
According to the given question an inequality 3|x+2| < 6 is given and we have to determine it's graph.
We know, 3|x+2|<6
= |x+2| < 2.
∴ (x+2) < 2
x < 0.
Or
-(x+2)<2.
- x - 2 < 2
- x < 4.
x > - 4. (Think of moving the values to other sides).
So, -4 < x < 0 and this will be represented in the number line by open circle and they are strictly less than and greater than.

What is the interquartile range of the lengths of bananas?
Answers
Answer:42/80
Step-by-step explanation:
We know that the shop only buys abanans with lengths between 13 cm and 20 cm.So, the fraction of the 80 bananas is actually a ratio between the y-values of each lenth (13 and 20 cm) and the total 80. First, let's see which y-values belong to each length.Notice that 13 belons to 20 at Cumulative Frequency. And 20 belongs to 62. So, the pairs are (13,20) and (20,62).This fraction means that the shop only buys 42 bananas out of 80, because those are between 13 cm and 20 cm.
The solution is: the interquartile range of the lengths of bananas is between 13 cm and 20 cm.
What is interquartile range?In descriptive statistics, the interquartile range tells you the spread of the middle half of your distribution. Quartiles segment any distribution that's ordered from low to high into four equal parts. The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set.
We know that the shop only buys bananas with lengths between 13 cm and 20 cm.
So, the fraction of the 80 bananas is actually a ratio between the y-values of each length (13 and 20 cm) and the total 80.

Find the equation of a line parallel to y−7=−3x that passes through the point (-6,6)
Answers
Answer:
y = -3x - 12
Step-by-step explanation:
y - 7 = -3x Put in the slope intercept form for a line
y = -3x + 7
Use the slope (-3), the x(-6) and the y(6) to find the y intercept and to write the equation for the line.
y = mx + b
6 = (-3)(-6) + b
6 = 18 + b Subtract 18 from both sides
-12 = b
y =mx + b
y = -3x -12

9,513 nearest thousands
Answers
9,513 rounded off to nearest thousands = 10,000
we have given a four digit number 9,513 to round off to nearest thousands.
steps that should be followed for rounding numbers to the nearest thousand:
Mark the number that we need to round. In this case, we will mark the digit in the thousands place. This rounding digit will be the one that will eventually be affected.Since we are rounding to the nearest thousand, we need to check the digit to the immediate right of the thousands place, that is the hundreds place.If the digit in the hundreds place is less than 5, we do not change the digit in the thousands place. However, all the digits to the right of the thousands place are changed to 0.If the digit in the hundreds place is 5 or more than 5, we increase the thousands place by 1, and all the digits to the right of the thousands place are changed to 0.round 9,513 to nearest thousands:
∵ hundreds place is 5
∴9,513≈10,000
hence, 9,513 nearest thousands is 10,000

Answers
Answer:
A) 0.23
B) 0.14
Step-by-step explanation:
Part A)
To solve this question, we'll have to use the Bernoulli formula.
The formula claims that the probability to get [tex]k[/tex] successes out of [tex]n[/tex] attempts is given by [tex]\binom{n}{k}p^k(1 - p)^{n - k}[/tex].
In our case, [tex]n = 5[/tex], [tex]k = 3[/tex], and [tex]p = 0.78[/tex].
Therefore, the probability that 3 out of the 5 drivers use their turn signal is
[tex]\binom53 \times 0.78^3 \times 0.22^2 \to 0.23[/tex]
Part B)
We are told that the police officer pulled over 5 drivers, 3 of them using turn signals. In this part, we are asked "what is the probability that the 5th driver uses the turn signal and only 2 of the previous four drivers use turn signals?".

Using long division what is the answer to 6.64 / 8.3?
Answers
Answer:
Step-by-step explanation:
Hey, don't worry, I got you! The answer is 0.8
The answer of 6.64 / 8.3 = 0.800
How do you do long division with decimals?When dividing a decimal by a whole number, use the same long division method as when doing so with two whole numbers, but place the decimal point in the answer exactly where it appears in the dividend. Add a 0 to the end of the payout and keep dividing until there is no remainder if it doesn't divide evenly.To convert these decimal numbers into whole numbers, the first step is to multiply each value by 10. Counting backwards from 3.5, we arrive at 35. The other number in our phrase, 15.75, cannot simply be multiplied by 10 once, as can be shown by looking at it. The result would be 157.5, which is still not a perfect number.Calculations :
We then have the equations:
66.4 ÷ 83 = 0.800
and therefore:
6.64 ÷ 8.3 = 0.800
Both calculated to 3 decimal places.

The volume (V) of Lorie's shed, being 18.25 ft in length, 15 ft in width and (5 1/5) ft in height, will be 1423.5 cubic fts.
As per the question statement, Lorie ordered a shed of length 18.25 ft, width 15 ft and height (5 1/5) ft, to hold her gardening supplies.
We are required to calculate the volume of the above mentioned shed using the formula, provided in the question statement itself.
To solve this question, we will simply put our values in the provided formula and calculate to obtain our desired answer.
Here, "l" = 18.25 ft
"w" = 15 ft,
And "h" =(5 1/5) =(25+1)/5=26/5=5.20ft.
Substituting the values of "l", "w" and "h" in the formula (V = lwh), we get,
Volume of the shed (V) = 18.25[tex]\times[/tex] 15 [tex]\times[/tex] 5.20

Taking into account the rule of three, the mass of 4000 atoms of gold is 1.3×10⁻¹⁸ grams.
Rule of threeThe rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, the direct rule of three must be applied as follow, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: x= (c×b)÷a
Mass of 4000 atoms of goldYou can apply the following rule of three: if 1 atom of gold has a mass of approximately 3.25×10⁻²² grams, 4000 atoms of gold have how much mass?
mass= (4000 atoms× 3.25×10⁻²² grams)÷ 1 atom
