Find the equation of the circle that has a diameter with endpoints located at (-3, 6) and (9, 6).
Answer: \((x+3)^2+(y-6)^2 = 36\\\\\)
==========================================================
Explanation:
If you apply the midpoint formula to the given points, you should find the midpoint is (3,6). This point represents the center of the circle. This means (h,k) = (3,6).
The radius is r = 6 because this is the distance from the center to either given endpoint. Either count out the spaces or use subtraction of the x coordinates. This works because the y coordinates are all the same.
Use those h, k and r values to plug them into the equation below
\((x-h)^2+(y-k)^2 = r^2\\\\(x-(-3))^2+(y-6)^2 = 6^2\\\\(x+3)^2+(y-6)^2 = 36\\\\\)
which represents the equation of the circle we're after.

We are aware that a discrete function is one that satisfies the criteria for a function and has a countable domain (represented as a collection of disconnected points) (each input has at most one output). Many inputs in discrete functions won't have any outputs.
According to the inquiry,
All three of the functions have a y-intercept and, given the facts in the question, f(x) is the highest maximum.
The largest maximum of the three functions—g(x), f(x), and f(y)—has an x-intercept.
Three distinct discrete functions are displayed in the table.
f(x)minimum: 1 g(x)minimum; -4 12 h(x)minimum-5; as a result, f(x)maximum: 10 g(x)maximum; 3 12 h(x)maximum; 12 f(x)domain; (0, 2) g(x)domain; (-2, 2) h(x)domain; (0, 1) g(x)y-inter (0, -5)
Using the procedures above, we may conclude that f(x) has no x.

Betsy sells laptops at an electronics store. She earns $180 a week, plus $15 for every laptop she sells. Betsy needs to earn at least $900 this week to meet her sales goal. Write and solve an inequality that can be used to determine the number of laptops Betsy needs to sell this week.
Answer:
15x + 180 ≥ 900
x ≥ 48
Step-by-step explanation:
x = amount of laptops needed to sell.
Equation:
15x + 180 ≥ 900
15x ≥ 720
x ≥ 48
Check:
15(48) + 180 = 900
720 + 180 = 900
900 = 900 (It's good, she needs to make at least 900, so she needs to sell at least 48 laptops).
what independent variable in costello et al. (2003) was not manipulated by the research team?
In Costello et al. (2003), the independent variable that was not manipulated by the research team was the gender of the participants.
The study examined the effects of different levels of alcohol consumption on cognitive performance and mood states in young adults. Participants were assigned to different alcohol consumption groups based on their self-reported drinking habits. However, the gender of the participants was not manipulated, and the study included both male and female participants. This means that any differences in the results based on gender cannot be attributed to the research team's manipulation of the independent variable, but rather to other factors that may have affected the results.

Triangle FGH (△FGH) is not similar to triangle JIH (△JIH) because their corresponding angles are not congruent and their corresponding sides are not proportional.
To prove that triangle FGH (△FGH) is not similar to triangle JIH (△JIH), we need to show that their corresponding angles and corresponding sides are not proportional.
1. Corresponding angles: In similar triangles, corresponding angles are congruent. If we compare the angles of △FGH and △JIH, we find that angle F in △FGH corresponds to angle J in △JIH, angle G corresponds to angle I, and angle H corresponds to angle H. Since the corresponding angles in both triangles are not congruent, we can conclude that the triangles are not similar.
2. Corresponding sides: In similar triangles, corresponding sides are proportional. Let's compare the sides of △FGH and △JIH. Side FG corresponds to side JI, side GH corresponds to side IH, and side FH corresponds to side HJ. If we measure the lengths of these sides, we can see that they are not proportional.

Determining the 3PL with the most distribution space requires specific data on the size and capacity of each company's facilities.
The 3PL identified as having the most distribution (warehousing) space in square feet cannot be determined without specific information or data.
There are many asset-based 3PLs in the logistics industry, and their distribution space can vary significantly based on factors such as company size, industry focus, geographic coverage, and investments in facilities.
Without specific data on the distribution space of each asset-based 3PL, it is not possible to determine which one has the most square footage.
Asset-based 3PLs are companies that own and operate their own assets, such as warehouses, trucks, and equipment, to provide logistics and supply chain services.
These companies often make significant investments in their facilities to ensure efficient storage and distribution of goods for their clients.
Some large 3PL providers may have extensive warehousing networks and substantial distribution space, while smaller or specialized providers may have more focused or limited warehouse capacities.

Suppose a large shipment of laser printers contained 12% defectives. If a sample of size 406 is selected, what is the probability that the sample proportion will be greater than 13%
The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
цр = р
The standard deviation of this sampling distribution of sample proportion is:
бр = √ρ(1-ρ)÷n
The information provided is:
ρ = 0.22
ⁿ = 276
As the sample size is large, i.e. n = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.
Compute the value of P(р-p<0.06) as follows:
P(р-p<0.06) = P(р-p ÷ бp<0.06 ÷√0.22(1 - 0.22) ÷ 276
= P ( Z < 2.41 )
= 0.99202
≈ 0.992
Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.

An enclosure at a zoo contains giraffes and ostriches. All together the zookeeper counts 70 heads and 200 legs. How many of each animal are there?
By solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.
A mathematical statement known as an equation is made up of two expressions joined by the equal sign.
A formula would be 3x - 5 = 16, for instance.
When this equation is solved, we discover that the number of the variable x is 7.
So, calculate as follows:
Let g represent giraffes and o represent ostriches.
g + o = 70 ...(1)
4*g + 2*o = 200 ...(2)
g = 70 - o, according to equation 1, therefore we may enter that number in place of g in equation 2 to obtain:
4*g + 2*o = 200
4*(70-o) + 2*o = 200
280 - 4o + 2o = 200
-2o = 200 - 280
2o = 80
o = 80/2
o = 40
Ostriches are 40 then giraffes will be:
70 - 40 = 30
Therefore, by solving equations we know that there are 30 giraffes and 40 ostriches in the zoo.

The mean on a test is 90, with a SD of 20. What raw score would be equivalent to a percentile rank of 29? E. On a distribution with a mean of 75 and a SD of 15, what raw score falls at the 95th percentile? F. The T score on a certain distribution is 26. The mean of the raw score distribution is 110 with a SD of 14.93. What is the value of the equivalent raw score?
A. The raw score for a percentile rank of 80 is approximately 82.4.
B. The raw score that falls at the 93rd percentile is 114.324.
C. The score that falls at the 11th percentile is 30.93.
D. The raw score that would be equivalent to a percentile rank of 29 is 79.20.
E. The raw score that falls at the 95th percentile is 99.75.
F. The value of the equivalent raw score is 74.17.
A. To calculate the raw score for a percentile rank of 80 first convert percentile rank to a z-score using the standard normal distribution table or a calculator.
The z-score corresponding to a percentile rank of 80 is approximately 0.84.
Then use the z-score formula to find the corresponding raw score.
z = (x - μ) / σ where, x is the raw score, μ is the mean, and σ is the standard deviation.
Plugging in the given values, we get:
0.84 = (x - 75) / 10
Solving for x, we get:
x = (0.84)(10) + 75 = 82.4
Therefore, the raw score for a percentile rank of 80 is approximately 82.4.
B. We can calculate the z-score from the percentile rank:
PR = 93
=> area to the left of z-score is 0.93.
Using the standard normal distribution table, the corresponding z-score is 1.48.
z = (x - μ) / σ
=> 1.48 = (x - 105) / 6.30
=> x = 105 + 1.48 * 6.30 = 114.324.
Therefore, the raw score that falls at the 93rd percentile is 114.324.
C. Similar to part A, we can calculate the z-score from the percentile rank:
PR = 11
=> area to the left of z-score is 0.11.
Using the standard normal distribution table, the corresponding z-score is -1.23.
z = (x - μ) / σ
=> -1.23 = (x - 38.70) / 6.31
=> x = 38.70 - 1.23 * 6.31 = 30.93.
Therefore, the score that falls at the 11th percentile is 30.93.
D. We can calculate the z-score from the percentile rank:
PR = 29
=> area to the left of z-score is 0.29.
Using the standard normal distribution table, the corresponding z-score is -0.54.
z = (x - μ) / σ
=> -0.54 = (x - 90) / 20
=> x = 90 - 0.54 * 20 = 79.20.
Therefore, the raw score that would be equivalent to a percentile rank of 29 is 79.20.
E. Similar to part A and C, we can calculate the z-score from the percentile rank:
PR = 95
=> area to the left of z-score is 0.95.
Using the standard normal distribution table, the corresponding z-score is 1.65.
z = (x - μ) / σ
=> 1.65 = (x - 75) / 15
=> x = 75 + 1.65 * 15 = 99.75.
Therefore, the raw score that falls at the 95th percentile is 99.75.
F. T-score is calculated as:
T = 10z + 50, where z is the z-score corresponding to the raw score.
26 = 10z + 50 => z = (26 - 50) / 10 = -2.4.
z = (x - μ) / σ => -2.4 = (x - 110) / 14.93 => x = 110 - 2.4 * 14.93 = 74.17.
Therefore, the value of the equivalent raw score is 74.17.
