9514 1404 393
Answer:
C) 4
Step-by-step explanation:
We observe that the top segments are in the same 3:4 ratio as the bottom segments. This means they are the same lengths: 3x = 12, 4x = 16. Either of these equations tells us x = 4.

Additional comment
In case you aren't convinced, you can solve this using the secant rule for segments and circles: the product of the lengths to the circle intercepts are the same for both secants.
12(12 +16) = 3x(3x +4x)
336 = 21x² . . . . . simplify
16 = x² . . . . . . . . divide by 21

Kody wants to test to be sure his soap dispenser design works fairly for people with different skin colors. He
selects separate random samples of 25 workers with light skin and 25 with dark skin. For each worker, he
measures the maximum distance from the dispenser at which it detects the employee's hand. Then he looks at
the difference in the sample means ( Light - TDark).
What do we know about the shape of the sampling distribution of Light - TDark, and why?
Answer: The shape cannot be determined since we don’t know the shape of either population distribution.

The pH of a liquid is a measure of how acidic or basic it is. The concentration of hydrogen ions in a liquid is labeled (H+). Use the formula pH = -log[H] to find the pH level, to the nearest tenth, of a liquid with [H] about 8.1 x 10-7,
a = 6.1
b = 7.9
с = -7.9
d = 7.0
Answer:
pH = 6.1
Step-by-step explanation:
pH = -log[H]
pH = -log[8.1 x 10^-7]
pH ≈ 6.09
Therefore, option a, 6.1, is closest to this value and is the correct answer.
Exercise 8.12 introduces data on the average monthly temperature during the month babies rst try to crawl (about 6 months after birth) and the average rst crawling age for babies born in a given month. A scatterplot of these two variables reveals a potential outlying month when the average temperature is about 53F and average crawling age is about 28.5 weeks. Does this point have high leverage
Answer:
The point has a high leverage
Step-by-step explanation:
The point has a high leverage as it would act as an infinitesimal point that will have a very huge/drastic impact on the fit of the model, and this impact can be seen in such ways as listed below :
Smaller coefficient of determinationHigher sum of squares errorremoving this point will eliminate these drastic impact and make the correlation to be better.
From the information given about the outliner, the given point is not influential and therefore does not have high leverage.
What is an outliner?An outlier refers to a data point whose response does not follow the general trend of the rest of the data.
A data point has high leverage if it has an extreme predictor x value. Here, x = 53 and, y = 28.5.
X is not an extreme point, the data point is not high leverage but an outlier. The data point doesn't follow the general trend of the rest of the data.
Hence the given point is not influential.

9 units is the answer.
Step-by-step explanation:

Pythagorean theorem can be written as,
[tex]d=\sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\\\d=\sqrt{(-10-(-10))^2 + (5-(-4))^2}\\\\d=\sqrt{(0)^2+(9)^2} \\\\d=\sqrt{81} \\\\d=9[/tex]

Two traffic lights operate independently. Your probability of being stopped at the first one is 0.4 and your probability of being stopped at the second one is 0.7. The probability at being stopped at the first light and second light is 0.3. What is your probability of being stopped at the first light or second light?Make sure to show your work. NEED HELP ASAP
Answer:
Most people found the probability of just stopping at the first light and the probability of just stopping at the second light and added them together. I'm just going to show another valid way to solve this problem. You can solve these kinds of problems whichever way you prefer.
There are three possibilities we need to consider:
Being stopped at both lights
Being stopped at neither light
Being stopped at exactly one light
The sum of the probabilities of all of the events has to be 1 because there is a 100% chance that one of these possibilities has to occur, so the probability of being stopped at exactly one light is 1 minus the probability of being stopped at both lights minus the probability of being stopped at neither.
Because the lights are independent, the probability of being stopped at both lights is just the probability of being stopped at the first light times the probability of being stopped at the second light. (0.4)(0.7) = 0.28
The probability of being stopped at neither is the probability of not being stopped at the first light, which is 1-0.4 or 0.6, times the probability of not being stopped at the second light, which is 1-0.7 or 0.3. (0.6)(0.3) = 0.18

The volume of cracker boxes are normally distributed, with a mean of 7 oz and a standard deviation of 0.2 oz. If a box is selected at random, What is the probability of getting an amount between that is at least 7.5 oz
Answer:
0.0062 = 0.62% probability of getting an amount between that is at least 7.5 oz.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 7 oz and a standard deviation of 0.2 oz.
This means that [tex]\mu = 7, \sigma = 0.2[/tex]
What is the probability of getting an amount between that is at least 7.5 oz?
This is 1 subtracted by the pvalue of Z when X = 7.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{7.5 - 7}{0.2}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a pvalue of 0.9938
1 - 0.9938 = 0.0062
0.0062 = 0.62% probability of getting an amount between that is at least 7.5 oz.

Find an equation for the nth term of the sequence.
-1, -4, -16, -64, ...
Answer:
An =4^(n-1)
Step-by-step explanation:
hello :
the sequence is geometric because : (-64)/(-16) = (-16)/(-4)=-4/-1= 4=r
the nth term is : An =A1 × r^(n-1)
a common ratio is : r and A1 the first term
in this exercice : r =4 A1 = 1
An =A1 × r^(n-1)
An =1 × 4^(n-1)=4^(n-1)
Find the measure of angle x 125
Answer:
x = 125 degrees
Step-by-step explanation:
The vertical angles theorem states that two angles opposite to each other that are formed from 2 intersecting lines are congruent.
Therefore, angle x and the angle that is 125 degrees are congruent to each other.
So, x=125 degrees.
