Answer:
3 2/5
Step-by-step explanation:
Add the distance she already ran, and subtract the sum from the total she needs to run.
Add two distances she ran:
3 1/2 + 2 1/2 = 3 + 2 + 1/2 + 1/2 = 5 + 1 = 6
Subtract sum from total:
9 4/10 - 6 = 3 4/10 = 3 2/5
Answer:
She needs to run 3 4/10 more miles
Step-by-step explanation:
If you add the amount she ran on Monday and the amount she ran on Tuesday you get 6 miles then subtract the 6 miles minus 9 4/10 you will get 3 4/10.

Write an expression that can be used to find the length of JH and an expression that can be used to find the length of GJ.
Answer: JH = 9 sin(35)
not sure about GH...
Step-by-step explanation:
The ratio of opposite side of the triangle hypotenuse side of triangle is equal to sine of angle.
The expression required to fine the length of GJ is,
[tex]\sin 35=\dfrac{GJ}{9}\\[/tex]
The length of the [tex]GJ[/tex] is 5.162 units.
What is right angle triangle?A right angle triangle is the triangle in which measure of one of the angle is equal to the 90 degrees.
The ratio of opposite side of the triangle hypotenuse side of triangle is equal to sine of angle.
Given information-
In the given triangle shown in the figure,
[tex]\angle JGH=35[/tex]
The angle [tex]\angle HJG[/tex] is right angle, which is equal to the 90 degrees.
As the sum of all the angles of a triangle is equal to the 180 degrees. Thus,
[tex]\angle JGH+\angle HJG+\angle GHJ=180\\[/tex]
Put the values,
[tex]35+90+\angle GHJ=180\\125+\angle GHJ=180\\\angle GHJ=180-125\\\angle GHJ=55[/tex]
In the given triangle, the side [tex]GJ[/tex] is the opposite side of the triangle and [tex]GH[/tex] is the hypotenuse side of the triangle.
Thus the length of the [tex]GJ[/tex] for the right triangle can be given as,
[tex]\sin 35=\dfrac{GJ}{9}\\[/tex]
This is the required expression,
[tex]GJ=\sin 35\times9\\GJ=0.574\times9\\GJ=5.162[/tex]
Thus the length of the [tex]GJ[/tex]5.162 units.
The expression required to fine the length of GJ is,

Each sample of water has a 10% chance of containing a particular organic pollutant. Assume that the samples are independent with regard to the presence of the pollutant. Find the probability that in the next 18 samples, exactly 2 contains the pollutant.
(a) P(x≥≥4)
(b) P(x≤≤4).
(c) P(3≤≤x≤≤7)
The probability that in the next 18 samples, exactly 2 contain the pollutant is
P(x = 2) =[tex]C(18, 2) (0.1)^2 (0.9)^16[/tex]
= 0.252.
The given is Each sample of water has a 10% chance of containing a particular organic pollutant.
Assume that the samples are independent with regard to the presence of the pollutant.
We need to find the probability that in the next 18 samples, exactly 2 contain the pollutant.
We can use the Binomial distribution formula to solve this problem.
The binomial distribution formula is given by:
P(x) = [tex]C(n, x) px qn-x[/tex]
Where n is the number of trials, x is the number of successes, p is the probability of success, and q is the probability of failure.
Since there is a 10% chance of containing a particular organic pollutant, the probability of success is:
p = 0.1
The probability of failure is:
q = 1 - p
= 1 - 0.1
= 0.9
Number of trials (samples) is n = 18
(a) To find P(x≥≥4)
We need to find the probability that 2 or more samples contain the pollutant.
We can do this by subtracting the probability that less than 2 samples contain the pollutant from 1.
P(x ≥ 2) = 1 - P(x < 2)P(x < 2)
= P(x = 0) + P(x = 1)P(x = 0)
= C(18, 0) (0.1)0 (0.9)18
= [tex]0.9^18[/tex]
P(x = 1) = [tex]C(18, 1) (0.1)^1 (0.9)^17[/tex]
= 0.33
P(x < 2) = [tex]0.9^18[/tex]+ 0.33
= 0.335
P(x ≥ 2) = 1 - 0.335
= 0.665
(b) To find P(x≤≤4)
We need to find the probability that 4 or less samples contain the pollutant.
P(x ≤ 4) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4)P(x = 0)
= C(18, 0) (0.1)0 (0.9)18
= [tex]0.9^18[/tex]
P(x = 1) = [tex]C(18, 1) (0.1)^1 (0.9)^17[/tex]
= 0.33
P(x = 2) = [tex]C(18, 2) (0.1)^2 (0.9)^16[/tex]
= 0.053
P(x = 3) = [tex]C(18, 3) (0.1)^3 (0.9)^15[/tex]
= 0.0047
P(x = 4) =[tex]C(18, 4) (0.1)^4 (0.9)^14[/tex]
= 0.0003
P(x ≤ 4) = 0.9^18 + 0.33 + 0.053 + 0.0047 + 0.0003
= 0.288
(d) To find P(3≤≤x≤≤7)
We need to find the probability that between 3 and 7 (inclusive) samples contain the pollutant.
P(3 ≤ x ≤ 7) = P(x = 3) + P(x = 4) + P(x = 5) + P(x = 6) + P(x = 7)P(x = 3)
= [tex]C(18, 3) (0.1)^3 (0.9)^15[/tex]
= 0.0047
P(x = 4) = C(18, 4) (0.1)^4 (0.9)^14
= 0.0003
P(x = 5) = [tex]C(18, 5) (0.1)^5 (0.9)^13[/tex]
= 0.00001
P(x = 6) = [tex]C(18, 6) (0.1)^6 (0.9)^12[/tex]
= 2.15e-07
P(x = 7) = [tex]C(18, 7) (0.1)^7 (0.9)^11[/tex]
= 4.7e-10
P(3 ≤ x ≤ 7) = 0.0047 + 0.0003 + 0.00001 + 2.15e-07 + 4.7e-10

Answer:
15 feet
Step-by-step explanation:
The distance from the foot of the ladder to the person is 6 feet. The person is also 6 feet. Therefore that mini triangle's length and width are both 6 feet.
The distance from the foot of the ladder to the wall is 15 feet. This is now a simple ratio. The length of the mini triangle is 6 to length of the larger triangle, 15. The height ratio is the mini triangle is 6 to the bigger triangle, x.
The height of the bigger triangle is the height of the wall. (Since the two are similar, then we can automatically deduce the height is 15.) But if you wanted to work out the ratio above ^^ you would multiply the 6 diagnol to the 15 and then divide by the last 6 to get 15.

The first 4-terms of sequence {aₙ} defined by recurrence-relation : aₙ₊₁ = 2aₙ²-1; a₁ = 0 are 0, -1, 1 and 1.
To find the first four terms of the sequence {aₙ} defined by the recurrence relation aₙ₊₁ = 2aₙ² - 1, with the initial-condition a₁ = 0, we apply the recurrence relation,
Starting with a₁ = 0, we can find the subsequent terms as follows:

⇒ a₃ = 2a₂² - 1 = 2(-1)² - 1 = 1
⇒ a₄ = 2a₃² - 1 = 2(1)² - 1 = 1

Let x = 9a - 7, where a is an integer. What is x mod 3?
For x = 9a - 7, where a is an integer, the value of x mod 3 is determined using the remainder when x is divided by 3, and it is equal to 2.
To find the value of x mod 3, we need to determine the remainder when x is divided by 3.
The expression x = 9a - 7, where a is an integer, allows us to calculate x mod 3.
To find x mod 3, we substitute the given expression x = 9a - 7 into the equation:
x mod 3 = (9a - 7) mod 3.
To simplify the expression, we can use the properties of modular arithmetic.
First, we can rewrite 9a as (3 × 3a) and distribute the modulus operator:
(9a - 7) mod 3 = ((3 × 3a) - 7) mod 3.
Next, we can separate the modulus operation:
((3 × 3a) - 7) mod 3 = ((3 × 3a) mod 3 - 7 mod 3) mod 3.
Since 3 is congruent to 0 mod 3, the first term becomes 0:
((3 × 3a) mod 3 - 7 mod 3) mod 3 = (0 - 7 mod 3) mod 3.
The second term, 7 mod 3, can be simplified as the remainder when 7 is divided by 3, which is 1:
(0 - 7 mod 3) mod 3 = (0 - 1) mod 3 = -1 mod 3.
Finally, we can find the remainder when -1 is divided by 3, which is 2:
-1 mod 3 = 2.
Therefore, x mod 3 is equal to 2.

Find the smallest sample size needed to estimate the percentage of Americans who prefer to watch the news rather than read or listen to it. Use a 0.03 margin of error and a confidence level of 99%. From a previous poll, it was found that 47% of the American respondents prefer to watch the news rather than read or listen to it.
To estimate the percentage of Americans who prefer to watch the news rather than read or listen to it with a 0.03 margin of error and 99% confidence level, the smallest sample size needed is 1,060.
To calculate the sample size, we can use the formula:
n = (Z² * p * (1 - p)) / E²
where:
n = sample size
Z = Z-score corresponding to the desired confidence level (in this case, for a 99% confidence level, Z ≈ 2.576)
p = estimated proportion of the population with the characteristic of interest (based on the previous poll, p = 0.47)
E = margin of error (E = 0.03)
Substituting the values into the formula, we have:
n = (2.576² * 0.47 * (1 - 0.47)) / 0.03²
n ≈ 1060
Therefore, the smallest sample size needed to estimate the percentage of Americans who prefer to watch the news rather than read or listen to it, with a 0.03 margin of error and 99% confidence level, is approximately 1,060. This means that a sample of at least 1,060 individuals should be surveyed to obtain reliable estimates with the desired level of confidence.

Which of the following statistical information about the data is calculated by the Column Statistics tool? Select the two correct answers ,Threshold calculation,Date analysis,Regression analysis,Median calculation
The correct answer is: Median calculation and Threshold calculation.
Median calculation: The Column Statistics tool can calculate the median of a dataset. The median is the middle value in a sorted dataset. It is a measure of central tendency that divides the data into two equal halves. Calculating the median can provide insights into the central value of a dataset and is less sensitive to extreme values compared to other measures like the mean.
Threshold calculation: The Column Statistics tool can calculate thresholds or cutoff points based on the data. These thresholds define certain conditions or ranges in the data. For example, you can set a threshold to identify data points above a certain value as outliers or flag data points that fall within a specific range. Threshold calculations can be useful for data cleansing, anomaly detection, or creating categorical variables based on certain conditions.
The other options, Date analysis and Regression analysis, are not typically calculated by the Column Statistics tool. Date analysis involves examining patterns and trends related to dates or time, which may require specialized techniques such as time series analysis or date-specific functions. Regression analysis is a statistical technique used to model the relationship between variables and requires more advanced tools or methods beyond basic column statistics.

phoebe compared the cost of books in 9 different stores. $2, $8, $4, $7, $8, $5, $8, $4, $6 what is the median cost of the books?
The median cost of the books is $6.
To find the median, we first arrange the costs of the books in ascending order: $2, $4, $4, $5, $6, $7, $8, $8, $8. Next, we determine the middle value. Since there are nine values, the middle value is the fifth one, which is $6. Therefore, the median cost of the books is $6.
The median is a statistical measure that represents the middle value of a dataset when it is arranged in ascending or descending order. It is useful in situations where there are outliers or extreme values that could skew the average. By using the median, we can get a better representation of the typical value in the dataset.
