It's A, 6.86 × 10⁴
Step-by-step explanation:
In scientific notation, you have the base, and the 10. The 10 is represented next to an exponent, whereas the base is a whole number and a decimal. If the decimal is moved right, the exponent following the 10 becomes negative. Left, it becomes positive. In this instance, the decimal is being moved left, thus the exponent is positive.

DIG DEEPER There are
9 pigeons on a curb. 3 of
them fly away, and some
of them jump down to the
street. There are 4 left. How
many pigeons jumped down
to the street?
Answers
There are 2 pigeons jumped down to the street.
Total no. of pigeons on a curb=9
No. of pigeons fly away=3
No. of pigeons stayed in the curb=4
Thus, the total number of pigeon that jumped down to the street is 9 - 3 - 4 = 2
This exemplifies the pigeonhole principle, which asserts that if there are more pigeons than there are pigeonholes, then there must be at least one pigeonhole with at least two pigeons in it. II) We can state that at least one box contains two or more objects if n + 1 things are placed within n boxes.
Hence, there are 2 pigeons jumped down to the street.

Figure ABCD is an isosceles trapezoid. Find the value of x. 8x-12 5x+9 (water spilled on my paper)
Answers
The value of x in the isosceles trapezoid is 7.
How to find angles of an isosceles trapezoid?An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure.
The base angles of an isosceles trapezoid are the same.
Therefore,
8x - 12 = 5x + 9
subtract 5x from both sides of the equation
8x - 12 = 5x + 9
8x - 5x - 12 = 5x - 5x + 9
3x - 12 = 9
add 12 to both sides of the equation
3x - 12 = 9
3x - 12 + 12 = 9 + 12
3x = 21
divide both sides by 3
x = 21 / 3
x = 7
Therefore, the value of x in the isosceles trapezoid is 7.

Faith is going to use a computer at an internet cafe. The cafe charges $0.80 for every minute using a computer on top of an initial charge of $3. Make a table of values and then write an equation for C,C, in terms of t,t, representing the total cost of using a computer for tt minutes at the internet cafe.
Answers
Here is the table of values:
Minutes Total cost
0 $3
1 $3.80
2 $4.60
3 $5.40
The equation representing the total cost is C = $3 + $0.80tt
What is the total cost?The total cost of using a computer is a function of the initial charge, cost per minute and total number of minutes the computer was used.
Total cost = initial charge + (cost per minute x number of minutes)
C = $3 + ($0.80 x tt)
C = $3 + $0.80tt
Total cost when the computer is used for one minute: C = $3 +( $0.80 x 1) = $3.80
Total cost when the computer is used for two minutes: C = $3 +( $0.80 x 2) = $4.60
Total cost when the computer is used for three minutes: C = $3 +( $0.80 x 3) = $5.40

$3100.00 is invested in an
account with a 3.2% interest rate
that is compounded quarterly.
How much money is in the
account at the end of one year?
Answers
Explanation:
For this problem, let’s assume that the money was put into the account on the first day of the year. With this in mind, we know that there are four quarters in a year. So, let’s set up a series of expressions to find the annually compounded interest.
Quarter 1: $3100 + ($3100 * .032) = $3199.2
Quarter 2: $3199.2 + ($3199.2 * .032) = $3301.5744
Quarter 3: $3301.5744 + ($3301.5744 * .032) = $3407.22478
Quarter 4: $3407.22477 + ($3407.22477 * .032) = $3516.25596
So, the exact amount would be $3516.25596. The rounded amount would be $3516.26.
We can extract from this series of expressions an equation to solve this faster.
Consider our base principle, P, and the interest, I. And let Q be the periods of interest, in our case quarters. We can say the following:
Returns = P (1 + I)^Q
With this we can calculate the same value as before:
P (1 + I)^Q
= 3100 (1+0.032)^4
= 3100 (1.13427612)
= 3516.25597
= $3516.26

Based on these data, a theory-based 99% confidence interval for the proportion of all adult Americans that drank coffee in the previous 24 hours is:
Answers
Using the z-distribution, the 99% confidence interval for the proportion of all adult Americans that drank coffee in the previous 24 hours is: (0.61, 0.65).
What is a confidence interval of proportions?A confidence interval of proportions is given by the following rule:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.For this problem, we have a 95% confidence level, hence the [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
The estimate and the sample size are given as follows:
[tex]\pi = 0.63, n = 2815[/tex]
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.63 - 1.96\sqrt{\frac{0.63(0.37)}{2815}} = 0.61[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.63 + 1.96\sqrt{\frac{0.63(0.37)}{2815}} = 0.65[/tex]
Hence the 99% confidence interval for the proportion of all adult Americans that drank coffee in the previous 24 hours is: (0.61, 0.65).

Mean: 5.0563 minutes.Variance: 7.9365 minutes².What is the missing information?The distribution of waiting times is missing, and is given by the image at the end of the answer.
The question is also incomplete, but it asks for the mean and the variance of the distribution.
What are the mean and the variance of a discrete distribution?The mean of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.The variance is given by the sum of the differences squared between each observation and the mean, multiplied by it's respective probability.Hence, from the distribution off the image, considering the percentages as the probabilities, the mean is given by:
E(X) = 0.0299 x 1 + 0.1026 x 2 + 0.1496 x 3 + 0.2265 x 4 + 0.1581 x 5 + 0.1368 x 6 + 0.0769 x 7 + 0.0214 x 8 + 0.0299 x 9 + 0.0299 x 10 + 0.0385 x 15 = 5.0563 minutes.
Then, considering the mean found above, and it's formula, the variance is given as follows:
V(X) = 0.0299 x (1 - 5.0563)² + 0.1026 x (2 - 5.0563)² + 0.1496 x (3 - 5.0563)² + 0.2265 x (4 - 5.0563)² + 0.1581 x (5 - 5.0563)² + 0.1368 x (6 - 5.0563)² + 0.0769 x (7 - 5.0563)² + 0.0214 x (8 - 5.0563)² + 0.0299 x (9 - 5.0563)² + 0.0299 x (10 - 5.0563)² + 0.0385 x (15 - 5.0563)² = 7.9365 minutes².

The values of trigonometric function are tanθ = -1 and cotθ = -1.
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
We have been given that trigonometric function
⇒ sinθ = √2/2
⇒ cosθ = -√2/2
We have to determine the function of tanθ and cotθ
Since tanθ = sinθ/cosθ
Substitute the values of sinθ = √2/2 and cosθ = -√2/2, we get
⇒ tanθ = (√2/2)/(-√2/2)
⇒ tanθ = (√2/2)×(-2/√2)
⇒ tanθ = -1
Since cotθ = cosθ/sinθ
Substitute the values of sinθ = √2/2 and cosθ = -√2/2, we get
⇒ cotθ = (-√2/2)/(√2/2)
⇒ cotθ = (√2/2)×(-√2/2)
⇒ cotθ = -1
Therefore, the values of trigonometric function are tanθ = -1 and cotθ = -1.
