Answer:
=19x−8 is your answer
Step-by-step explanation:
=7x−11+−1(−12x−3)
=7x+−11+−1(−12x)+(−1)(−3)
=7x+−11+12x+3
Combine Like Terms:
=7x+−11+12x+3
=(7x+12x)+(−11+3)
=19x+−8
Answer:
19x-8
Step-by-step explanation:
7x plus -12x is 19x. you then subtract 11 from 3 and you get 8
Sarah would like to build a garden this year. Sarah measured out the outside of her proposed garden and would like to know how many square feet of space she will have to use. Calculate the area of her garden from the picture below.
show your work please it's required
Answer:
122 ft²Step-by-step explanation:
Divide the area into 3 parts as below.
Calculate each area and add up:
A1 = 7*11 = 77 ft²A2 = 8*5 = 40 ft²A3 = 1/2*2*5 = 5 ft²Total area:
77 + 40 + 5 = 122 ft²1. A fair 20-sided dice with faces numbered from 1 to 20 is rolled. The event M is defined
as “the number obtained is a multiple of 3”.
a. Determine P(M). If the dice is rolled 100 times.
b. How many times would you expect to get a multiple of 3?
Answer:
you wouldn't get to many unless every time you roll you get an odd number and if you end up with that you can expect to get a number counted by 3 at least 6 times

Complete the following statement about the Empirical Rule.
According to the Empiricalâ Rule, if a distribution isâ bell-shaped, then approximately _______________ of the data will lie within 1 standard deviation of theâ mean; approximately ____________ 95% 99.7% 68% of the data will lie within 2 standard deviations of theâ mean; approximately ______________ 68% 95% 99.7% of the data will lie within 3 standard deviations of the mean.
Answer:
1. 68%
2. 95%
3. 99.7
Step-by-step explanation:
Standard deviation of mean will be 68%, 95%, and 99.73% respectively.
What is Empirical Rule?A statistical rule known as the empirical rule, which is also known as the three-sigma rule or the 68-95-99.7 rule, states that almost all observed data for a normal distribution will be within three standard deviations of the mean or average.
Given according to the empirical rule, 68% of observations will fall within the first standard deviation (µ ± σ), 95% will fall within the first two standard deviations (µ ± 2σ), and 99.7% will fall within the first three standard deviations(µ ± 3σ) .
Hence SD of mean will be 68%, 95%, and 99.73%

In a survey of 314 job recruiters, 46% said that they had reassessed a job candidate after viewing his/her social media profile and content. (This includes both positive and negative reassessments of the job candidate.) Construct a 90% confidence interval for the proportion of job recruiters who reassessed a job candidate after viewing his/her social media content.
Answer:
The 90% confidence interval for the proportion of job recruiters who reassessed a job candidate after viewing his/her social media content is (0.4137, 0.5063).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
In a survey of 314 job recruiters, 46% said that they had reassessed a job candidate after viewing his/her social media profile and content. (This includes both positive and negative reassessments of the job candidate.)
This means that [tex]n = 314, \pi = 0.46[/tex]
90% confidence level
So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.46 - 1.645\sqrt{\frac{0.46*0.54}{314}} = 0.4137[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.46 - 1.645\sqrt{\frac{0.46*0.54}{314}} = 0.5063[/tex]
The 90% confidence interval for the proportion of job recruiters who reassessed a job candidate after viewing his/her social media content is (0.4137, 0.5063).

i don't really understand this problem
Answer:
Step-by-step explanation:
So what you need to do is mark to points on the graph. For example (9,4) and (18,8). The run would be 9 and the rise would be 4. Gradient = rise/run which is 4/9. So that's the gradient. Now it asks for the equation. The formula for an equation is y=mx+c m= the gradient and c = the y-intercept (the y intercept is where the line meets the axis so it would be 0) so the answer is: y=4/9x+0.
