using exponents, the number 1/1000 is 10 ? . what is the exponent?
Answer:
10^3
Step-by-step explanation:
what is abc’s basis in the assets purchased if abc pays $70,000 for them?
The basis of $70,000 represents the cost incurred by ABC to acquire the assets, serving as a starting point for accounting and tax purposes.
When abc pays $70,000 for the assets, that amount becomes the basis of the assets for abc. The basis represents the cost or value assigned to the assets for accounting and tax purposes. It is used to determine the potential gain or loss when the assets are sold or disposed of in the future.
The basis in the assets is important because it affects the calculation of depreciation, which is the systematic allocation of the cost of the assets over their useful life. By knowing the basis, abc can determine the amount of depreciation expense to be recognized each year.
Additionally, the basis is crucial for determining the gain or loss on the sale of the assets. If abc decides to sell the assets in the future, the basis will be subtracted from the sale price to calculate the taxable gain or loss. A higher basis would result in a lower taxable gain or a higher deductible loss.
In summary, when abc pays $70,000 for the assets, that becomes the basis of the assets. The basis is used for calculating depreciation and determining the gain or loss on the sale of the assets.

Would you factor out the GCF, use the Perfect Square Trinomial pattern, or the Difference of Squares Pattern? 4x^2 - 25 2. Show how you would use the approach you picked by factoring this binomial.
The factored form of the binomial 4x^2 - 25 is (2x - 5)(2x + 5).
To factor the binomial 4x^2 - 25, we can use the Difference of Squares pattern. This pattern applies when we have a binomial in the form of a^2 - b^2, where a and b are terms. In the given expression, 4x^2 - 25, we can see that 4x^2 is the square of 2x and 25 is the square of 5. Therefore, we can rewrite the expression as (2x)^2 - 5^2. Applying the Difference of Squares pattern, we have: 4x^2 - 25 = (2x)^2 - 5^2 = (2x - 5)(2x + 5). So, the factored form of the binomial 4x^2 - 25 is (2x - 5)(2x + 5). By using the Difference of Squares pattern, we were able to factor the binomial into two binomial factors. The pattern states that the difference of two squares can be expressed as the product of two binomials, with one binomial being the sum of the square roots of the terms and the other binomial being the difference of the square roots of the terms.

I think once I did something like is their life on other planets in our solar system. I started by defining life talking about what life needs, and you get the idea
the employees of a company were surveyed on questions regarding their educational background and marital status. of the 600 employees, 400 had college degrees, 100 were single, and 60 were single college graduates. the probability that an employee of the company is single or has a college degree is:
The probability that an employee of the company is single or has a college degree is 7/5 or 1.4.
The probability that an employee of the company is single or has a college degree can be calculated using the principle of inclusion-exclusion.
From the given information, we know that there are 600 employees in total, 400 of whom have college degrees and 100 of whom are single. We are also given that 60 employees are both single and college graduates.
To find the probability that an employee is single or has a college degree, we can add the probabilities of being single and having a college degree and then subtract the probability of being both single and a college graduate, since we would be counting those employees twice.
Let's denote the event of an employee being single as S, and the event of an employee having a college degree as C. Using these notations, we can calculate the probability as follows:
P(S or C) = P(S) + P(C) - P(S and C)
P(S or C) = 100/600 + 400/600 - 60/600
P(S or C) = 1/6 + 2/3 - 1/10
P(S or C) = 5/10 + 10/10 - 1/10
P(S or C) = 14/10
P(S or C) = 7/5
Therefore, the probability that an employee of the company is single or has a college degree is 7/5 or 1.4.
In other words, there is a 1.4 probability that a randomly selected employee is either single or has a college degree.
To understand the calculation, we can break it down into individual probabilities. Out of the 600 employees, 100 are single, which gives us a probability of 100/600 or 1/6. Additionally, out of the 600 employees, 400 have college degrees, so the probability of having a college degree is 400/600 or 2/3.
However, if we simply add these probabilities, we would be counting the employees who are both single and college graduates twice. To correct this, we need to subtract the probability of being both single and a college graduate. From the given information, we know that there are 60 employees who fall into this category, which gives us a probability of 60/600 or 1/10.
By applying the principle of inclusion-exclusion, we add the probabilities of being single and having a college degree, and then subtract the probability of being both single and a college graduate to obtain the final probability of 7/5 or 1.4.

If there are 16 people in a hospital and 4 need an xray.
What is the probabilty that if you choose 2 people randomly, exactly one will need an xray?
The probability that if you choose 2 people randomly, exactly one will need an x-ray is 0.4.
The probability that if you choose 2 people randomly from the 16 in the hospital, exactly one will need an x-ray is as follows:
Firstly, calculate the probability of choosing one person who needs an X-ray and one person who doesn't.
There are 4 people who need an x-ray and 12 who don't, so the probability for this is (4/16) * (12/15).
Now, calculate the probability of choosing one person who doesn't need an X-ray and one person who does. This is (12/16) * (4/15).
Now, add the probabilities to find the total probability.
The probability that exactly one person will need an x-ray is
(4/16) * (12/15) + (12/16) * (4/15) = 2/5
=0.4.

The probability that if you choose 2 people randomly, exactly one will need an x-ray is 0.4 or 40%.
If there are 16 people in a hospital and 4 need an xray, the probability that if you choose 2 people randomly, exactly one will need an xray is 0.56.
Total number of people in a hospital = 16
Number of people who need an x-ray = 4
Thus, the probability that if you choose 2 people randomly, exactly one will need an x-ray is given by;
P(one needs an x-ray) = (Number of people who need an x-ray × Number of people who do not need an x-ray) / Total number of people × Total number of people - 1
P(one needs an x-ray) = (4 × 12) / 16 × 15
P(one needs an x-ray) = 0.08
P(one doesn't need an x-ray) = (Number of people who need an x-ray × Number of people who do not need an x-ray) / Total number of people × Total number of people - 1
P(one doesn't need an x-ray) = (12 × 4) / 16 × 15
P(one doesn't need an x-ray) = 0.32
Now, we have to add both the probabilities of exactly one person needing an x-ray and exactly one person not needing an x-ray;
P(exactly one person needs an x-ray) = P(one needs an x-ray) + P(one doesn't need an x-ray)
P(exactly one person needs an x-ray) = 0.08 + 0.32P(exactly one person needs an x-ray) = 0.4
The probability that if you choose 2 people randomly, exactly one will need an x-ray is 0.4 or 40%.

in the morning, about 28% of adults know what they will have for dinner. if one morning, you ask 22 adults if they know what they will have for dinner, what is the probability that more than 6 will say yes? group of answer choices 0.610 0.423 0.188 0.390
By applying the binomial distribution formula, it can be concluded that the probability that more than 6 will say yes is 0.423 (option B).
Combination is the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed.
C(n,r) = n! / (r! (n-r)!) where
n = number of samples
r = number of selected samples
The binomial distribution formula is used to find the probability of the specific outcome in a discrete distribution.
P(X) = C(n,r) * \(p^{r}\) * \(q^{n-r}\) where:
C = combination value
p = probability of success on a single trial
q = probability of failure on a single trial
n = 22
p = 28% = 0.28
q = 1 - 0.28 = 0.72
The probability that r adults will say yes is given by the binomial distribution:
P(X=r) = C(n,r) * \(p^{r}\) * \(q^{n-r}\)
= C(22,r) * \(0.28^{r}\) * \(0.72^{22-r}\)
P(X≤6) = P(X=0) + P(X=1) + P(X=2) + P(X=3) + P(X=4) + P(X=5) + P(X=6)
Now we calculate for each probability:
P(X=0) = C(22,0) * 0.28⁰ * 0.98²² = 0.000726633
P(X=1) = C(22,1) * 0.28¹ * 0.98²¹ = 0.00621676
P(X=2) = C(22,2) * 0.28² * 0.98²⁰ = 0.025385
P(X=3) = C(22,3) * 0.28³ * 0.98¹⁹ = 0.0658131
P(X=4) = C(22,4) * 0.28⁴ * 0.98¹⁸ = 0.121571
P(X=5) = C(22,5) * 0.28⁵ * 0.98¹⁷ = 0.1702
P(X=6) = C(22,6) * 0.28⁶ * 0.98¹⁶ = 0.187535
If we sum up the results, we get P(X≤6) = 0.577447493
P(X>6) = 1 - P(X≤6)
= 1 - 0.577447493
= 0.422552507
≈ 0.423
Thus the probability that more than 6 will say yes is 0.423.

slope-intercept from two points (4,-8) and (8,5)
Here you go :)
Slope is equal to the change in y over the change in x or rise over run:
m = change in y/change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise):
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope:
m=5−(−8)/8−(4)
Simplify:
m=13/4
Substitute the value of m into the slope-intercept form of the equation, y = m x + b :
y=(13/4)x+b
Substitute the value of x into the slope-intercept form of the equation, y = m x + b .
y = ( 13/ 4 ) ⋅ ( 4 ) + b
Substitute the value of y into the slope-intercept form of the equation, y = m x + b .
− 8 = ( 13/ 4 ) ⋅ ( 4 ) + b
Rewrite the equation as ( 13 4 ) ⋅ ( 4 ) + b = − 8 .
( 13/ 4 ) ⋅ ( 4 ) + b = − 8
Cancel the common factor.
13/ 4 ⋅ 4 + b = − 8
Rewrite the expression.
13 + b = − 8
Move all terms not containing b to the right side of the equation.
b = − 21
The values of the slope and y-intercept are m = 13 4 and b = − 21 .
m = 13 4
