W=
Answers
Answer:
w= -1
Step-by-step explanation:
Use PEMDAS to solve.
9(1 + w) - 5w = 5
distribute 9 to everything inside the parentheses.
9 x 1 = 9
9 x w = 9w
rewrite equation
9 + 9w - 5w = 5
combine like terms
9w - 5w = 4w
rewrite equation
9 + 4w = 5
subtract 9 from both sides
9 - 9 = 0
5 - 9 = -4
rewrite equation
4w = -4
divide by 4 on both sides to get w by itself.
4w / 4 = w
-4 / 4 = -1

Answers
Answer:
AC = 29.96cm
Step-by-step explanation:
The sum of the angles inside a triangle is equal to 180 degrees. We are told that angle a is 57°, and that angle B is 73°. This tells us that angle C is (180 - 57 - 73)°, or 50°.
We are also given the length of side AB 24cm, with that we can use the sine rule to calculate the length of side AC:
sin (B) / |AC| = sin (C) / |AB|
sine (73°) / |AC| = sin(50°) / 24cm
AC = 24 cm • sin(73°) / sin(50°)
AC = 29.96 cm

Write an equation for the nth term of the arithmetic sequence. Then find a 30
-9, -6, - 3,0, ...
Answers
Answer:
The nth term is given by: [tex]a_n = -9 + 3(n-1)[/tex]
The 30th term is 78.
Step-by-step explanation:
Arithmetic sequence:
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n-1)d[/tex]
In which [tex]a_1[/tex] is the first term and d is the common difference between terms.
-9, -6, - 3,0
This means that [tex]a_1 = -9, r = -6 - (-9) = -6 + 9 = 3[/tex]. So
[tex]a_n = -9 + 3(n-1)[/tex]
30th term:
[tex]a_30 = -9 + 3(30-1) = -9 + 87 = 78[/tex]
The 30th term is 78.
A coffee pot had 1
1/2 pints of coffee.
After a mug was
filled, there were 1
pint left in the pot.
How many ounces of
coffee were in the
mug?
Answers
Answer:
8 ounces
Step-by-step explanation:
Since there was 1 pint left, that means the mug had 1/2 pints of coffee.
Now, convert this to ounces. There are 16 ounces in a pint, so we can find how many ounces there were by multiplying 16 by 1/2
16(1/2)
= 8
So, there were 8 ounces of coffee in the mug

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.
Answers
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.

A pound of coffee beans yields 50 cups of coffee. How many mL of coffee can be obtained from 10.0 g of coffee beans? (1 lb =454 g, 1 L= 1.0567 qt, 4 cups=1 qt, 1 L=1000 mL)
Answers
Answer:
260.55682 mL
Step-by-step explanation:
Given :
(1 lb =454 g, 1 L= 1.0567 qt, 4 cups=1 qt, 1 L=1000 mL)
1 pounds of coffee beans = 50 cups of coffee
Number of mL of coffee that can be obtainwd from 10 g of coffee beans
1 pound = 454g
10 * 50 cups = 500 cups / 454 = 1.1013215 cups
1.1013215 / 4 = 0.2753303 qt
0.2753303 qt / 1.0567 qt = 0.2605568 L
0.2605568 L * 1000 = 260.55682 mL
