Step-by-step explanation:
Find (7x−11)−(−12x−3).
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

• Yogi is planning a concert for his animal friends. He arranges his chairs and if he makes 8 rows he was
3 chairs short. If he has 6 rows he has 17 chairs left over. How many chairs does Yogi have?
Answer: Yogi has 59 chairs.
Step-by-step explanation: For the question, it's a lot of guess an check. 10 is a good place to start. Times 10 by 8 and add 3. Then times 6 by 10 and add 17. Does it equal the same number? No. Is it close? Yes. So maybe try going up a few numbers or down a few. You'll eventually get 7 which when you multiple 7 by 8 and add 3 and multiple 6 by 10 and add 17, you'll get 59.

Answer:
-95.1428571429
Step-by-step explanation:
You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. From a random sample of 40 business days, the mean closing price of a certain stock was $108.50 . Assume the population standard deviation is$11.36 . The 90% confidence interval is (nothing ,nothing ).(Round to two decimal places as needed.) The 95% confidence interval is (nothing ,nothing ). (Round to two decimal places as needed.) Which interval is wider? Choose the correct answer below. The 95% confidence interval The 90% confidence interval Interpret the results. A. You can be 90% confident that the population mean price of the stock is outside the bounds of the90% confidence interval, and 95% confident for the 95% interval. B. You can be certain that the population mean price of the stock is either between the lower bounds of the 90% and 95% confidence intervals or the upper bounds of the 90% and 95% confidence intervals. C. You can be 90% confident that the population mean price of the stock is between the bounds of the 90% confidenceinterval, and 95% confident for the 95% interval. D. You can be certain that the closing price of the stock was within the 90% confidence interval for approximately 36 of the 40 days, and was within the 95% confidence interval for approximately 38 of the 40 days.
Answer:
The 90% confidence interval is ($105.55,$111.45)
The 95% confidence interval is ($104.98,$112.02)
The 95% confidence interval is wider.
C. You can be 90% confident that the population mean price of the stock is between the bounds of the 90% confidenceinterval, and 95% confident for the 95% interval.
Step-by-step explanation:
90% confidence interval:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.645\frac{11.36}{\sqrt{40}} = 2.95[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 108.50 - 2.95 = $105.55
The upper end of the interval is the sample mean added to M. So it is 108.50 + 2.95 = $111.45
The 90% confidence interval is ($105.55,$111.45)
95% confidence interval:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.96\frac{11.36}{\sqrt{40}} = 3.52[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is 108.50 - 3.52 = $104.98
The upper end of the interval is the sample mean added to M. So it is 108.50 + 3.52 = $112.02
The 95% confidence interval is ($104.98,$112.02)
Which interval is wider?
The 95% confidence interval has a larger margin of error, so it is wider.
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
So the correct interpretation is:
C. You can be 90% confident that the population mean price of the stock is between the bounds of the 90% confidenceinterval, and 95% confident for the 95% interval.

An experiment consists of first rolling a die and then tossing a coin. (a) List the sample space. {(3, H), (4, H)} {(1, T), (2, T), (3, T), (4, T), (5, T), (6, T)} {(1, H), (1, T), (2, H), (2, T), (3, H), (3, T), (4, H), (4, T), (5, H), (5, T), (6, H), (6, T)} {(3, H), (3, T), (4, H), (4, T)} {(1, H), (2, H), (3, H), (4, H), (5, H), (6, H)} (b) Let A be the event that either a three or a four is rolled first, followed by landing a head on the coin toss. Find P(A). (Enter your probability as a fraction.)
Answer:
(a)
[tex]S = \{(1,H),(2,H),(3,H),(4,H),(5,H),(6,H),(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)\}[/tex]
(b)
[tex]P(A) = \frac{1}{6}[/tex]
Step-by-step explanation:
Given
The above sample space
A = Event of an occurrence of 3 or 4 then a head
(a): List out the sample space:
The rolls of the dice come first, followed by the toss of the coin.
So, the sample space are:
[tex]S = \{(1,H),(2,H),(3,H),(4,H),(5,H),(6,H),(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)\}[/tex]
The number of the sample space is:
[tex]n(S) = 12[/tex]
(b): Find P(A)
First, we list out the outcomes of event A
[tex]A = \{(3,H),(4,H)\}[/tex]
The number of outcome is:
[tex]n(A) = 2[/tex]
The probability of A is then calculated as:
[tex]P(A) = \frac{n(A)}{n(S)}[/tex]
[tex]P(A) = \frac{2}{12}[/tex]
Simplify fraction
[tex]P(A) = \frac{1}{6}[/tex]

True
Step-by-step explanation:
how do you use unit multipliers
Answer:
A unit multiplier (or conversion factor) is a fraction with value 1 that we use to convert quantities. Because the value of every unit multiplier is 1, we can multiply any quantity by them, without changing their value. Principles behind the technique: ! We never change the value of a quantity if we multiply it by 1.

find sin θ and cos θ if tan θ= 1/4 and sin 0>0.
Answer:
[tex]\displaystyle \sin(\theta)= \frac{\sqrt{17}}{17}[/tex]
[tex]\displaystyle \cos(\theta)= \frac{4 \sqrt {17} }{ 17 }[/tex]
Step-by-step explanation:
We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.
First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.
Recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the hypotenuse is:
[tex]h=\sqrt{4^2+1^2}=\sqrt{16+1}=\sqrt{17}[/tex]
So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.
Then it follows that:
[tex]\displaystyle \sin(\theta)=\frac{1}{\sqrt{17}} = \frac{\sqrt{17}}{17}[/tex]
And that:
[tex]\displaystyle \cos(\theta)= \frac{4}{\sqrt{17}} = \frac{4 \sqrt {17} }{ 17 }[/tex]
9 = 4t what is t please help me
Answer:
t=2.25
Step-by-step explanation:
9 divided by 4 is 2.25
and 4 x 2.25 is 9
Answer t = 9/4
Divide both sides of the equation by the same term
9 = 4t
9/4=9/4
