Solve the equation. Then check your solution. 6 = negative 2 (10 n + 7)
Answers
n = - 1
Step-by-step explanation:Hi !
6 = - 2(10n + 7)
6 = - 20n - 14
20n = - 6 - 14
20n = - 20
n = - 20 : 20
n = - 1
6 = - 2(10×-1 + 7)
6 = - 2(-10 + 7)
6 = - 2(-3)
6 = 6 (true)
Good luck !
Answer:
n = -1 OR -1 = n
Step-by-step explanation:
6 = -2(10n +7)
First we remove the brackets by multiplying the inner numbers by -2
6 = -20n - 14
Then we add 14 on both sides
20 = -20n
We make n the subject and divide both sides by -20
n = -1 OR -1 = n

you distribute the 3 to the numbers in the first set of parentheses and you distribute a -1 to the numbers in the second set of parentheses. then you combine like terms, which are 3x and -x, and 27 and 6

Listed below are selling prices (dollars) of TVs that are 60 inches or larger and rated as a "best buy" by a popular magazine. Are the resulting statistics representative of the population of all TVs that are 60 inches and larger? If you decide to buy one of these TVs, what statistic is most relevant, other than the measures of central tendency?
1550 1650 1600 1650 1500 1200 1650 1800 1200 1050 1650 1850
Answers
Answer:
Step-by-step explanation:
a) Mean the sum total of the given variables divided by the sample size given.
Mean = (Σx)/N
Σx = 1550 +1650 +1600 +1650 +1500 +1200 +1650+ 1800+ 1200 +1050 +1650+ 1850
Σx = 18,350
N = 12
Mean = 18,350/12
Mean = 1529.17
b) Median is the data at the middle if the given dataset after rearrangement. Arrangement can either be in ascending or descending order.
Rearranging the dataset in ascending order of magnitude.
1050 1200 1200 1500 1550 (1600 1650) 1650 1650 1650 1800 1850
It is seen that two values 1600 and 1650 are values that falls in the middle, hence we will take their average.
Median = 1600+1650/2
Median = 1625
c) Mode is the value in the dataset that occur the most i.e value with the highest frequency. According to the data only 1650 occurs 4 times, hence the mode of the data is 1650.
d) Midrange of the data is the average of the highest values and the Lowest value.
Midrange = Maximum value+Minimum value/2
Max value = 1850
Min value = 1050
Midrange = 1850+1050/2
Midrange = 2900/2
Midrange = 1450
4) No, the resulting statistics are not representative of the population of all TVs that are 60 inches and larger because it is given that the dataset provided is for the selling prices of TVs that are 60 inches or larger and rated as a "best buy" by a popular magazine, therefore we can conclude that, the dataset is representative of the best type of TVs that are 60 inches and larger and not all the sets of TVs
- The measure of dispersion relevant is the STANDARD DEVIATION other than the measures of central tendencies above because it shows how the selling prices of the different best TVs varies especially that of variation from the mean.

Answer:

Step-by-step explanation:
Note how both triangles are isosceles triangles, which mean two angles will be equivalent. In the triangle with the marked angle measurement, since the total of angles in a triangle is 180, then the measurement of the unmarked angles have a sum of 180-64, which is 116. Then, as stated before, this triangle is isosceles, so the measurement of each unmarked angle is 116/2, which is 58.
Next, notice how the angle below angle x in that triangle shares a line with one of the 58 degree angles. This means that angle is 180-58, which is 122. Now, since the total of angles in a triangle is 180 and the triangle is isosceles, then angle x is (180-122)/2, which is 58/2, or 29 degrees

2. The probability of a success must remain constant in a binomial experiment.
(a) Explain why this is true.
(b) How does this relate to the requirement of independence in a binomial experiment?
Answers
Answer:
It takes about 18m
Step-by-step explanation:
An experiment is said to be binomial in nature if and only if it obeys the following conditions which include :
Fixed number of trials Each trial must be independent Only two possible outcomes Probability of success on each trial is the same.When an experiment obeys these conditions, then it can be adjudged to be a binomial experiment.
The probability of success on each trial must the same, this also allows the probability of failure to be the same throughout the experiment since there are only two possible outcomes on each trial and the outcomes are equally likely. Independence in a binomial experiment entails that, each individual trial does not depend on the result or outcome of the previous trial, since the probability of success is constant all through the experiment, then independence of each trial is a necessary prerequisite for a binomial experiment.Hence, a binomial experiment must meet the four listed requirements.

Some researchers postulate the frequency of colds can be dramatically reduced with regular exercise. In 2010, a group of researchers published an article related to this research question in Medical News Today. The article was based on the findings of a study by researcher David Nieman that followed 1,002 randomly selected people aged 18-85 years for 12 weeks, asking them whether they usually exercise 5 or more days per week (Yes or No) as well as having them record on a weekly basis whether they had a cold during the previous week (Yes or No).
Suppose the researcher would like to plot the data on whether the study participants usually exercised or more days per week. Which of the following would be an appropriate graph?
a. bar chart
b. a scatterplot
c. parallel boxplots
d. a single histogram
Answers
Answer:
Option a (Bar Chart) is the right approach.
Step-by-step explanation:
Even before we want to equate or compare the distinct types, a bar chart was being used, it is a set of productivity and profitability, with either the price fluctuations over a given time displayed by each bar.
We would like to compare two different groups here:
Individuals who work out five days a week or even more than that. Someone who doesn't do 5 or maybe more days of exercising.The other options offered were never relevant to the relation or condition presented. So, option b seems to be the correct one.

A. 375 hours
B. 200 hours
C. 6.25 hours
D. 4.5 hours
Answers
Because if it takes 50 minutes to run 4 miles you need to divide 50/4 and you will get 12.5 and then multiply that by 30 cause she is trying to run 30 miles and that will get you 375 and then divide that by 60 cause their are 60 minutes in a hour and you will get 6.25

[tex]= \frac{2}{3} \frac{4}{4}\\= \frac{2 \times 4}{3 \times 4} \\= \frac{8}{12}[/tex]
For the fraction 3/4
[tex]= \frac{3}{4} \frac{3}{3}\\= \frac{3 \times 3}{4 \times 3} \\= \frac{9}{12}[/tex]
For the fraction 5/6;
[tex]= \frac{5}{6} \frac{2}{2}\\= \frac{5 \times 2}{6 \times 2} \\= \frac{10}{12}[/tex]

Use the LCD to rewrite the 1/6 and 3/8 with the same denominator.
Answers
Answer:
1/6 becomes 4/24 and 3/8 becomes 9/24.
Step-by-step explanation:
The LCD of the denominators is 24 because that is the lowest number that 6 and 8 are both related too (6 times 4 is 24, and 8 times three is 24). Since 6 goes into 24 4 times, multiply 1 (the numerator) by 4 and you get 4. Since 8 goes into 24 3 times, multiply 3 (the numerator) by 3 and you get 9.
