Use the given information to find the minimum sample size required to estimate an unknown population mean μ.
How many students must be randomly selected to estimate the mean weekly earnings of students at one college? We want 95% confidence that the sample mean is within $4 of the population mean, and the population standard deviation is known to be $25.
Answer:
151 students must be selected.
Step-by-step explanation:
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.
The population standard deviation is known to be $25.
This means that [tex]\sigma = 25[/tex]
How many students must be randomly selected to estimate the mean weekly earnings of students at one college? Sample mean within $4 of the population mean
This is n for which M = 4. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]4 = 1.96\frac{25}{\sqrt{n}}[/tex]
[tex]4\sqrt{n} = 1.96*25[/tex]
[tex]\sqrt{n} = \frac{1.96*25}{4}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96*25}{4})^2[/tex]
[tex]n = 150.1[/tex]
Rounding up:
151 students must be selected.

Describe how to use a conversion factor to convert units. PLEASE HELP DUE TONIGHT
Answer:
A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

solve these equations, show all your work x-2=10 and x+6=13
Answer:
x = 12 , x = 7
Step-by-step explanation:
x-2 = 10
x= 10+2 = 12
x+6 = 13
x=13-6
x=7
Answer:
x = 9.5
If they were separate equations,
x - 2 = 10 ⇒ x = 12
x + 6 = 13 ⇒ x = 7
Step-by-step explanation:
x - 2 + x + 6= 10 + 13
2x + 4 = 23
2x + 4 - 4 = 23 - 4
2x = 19
2x ÷ 2 = 19 ÷ 2
x = 9.5
If they were separate,
x - 2 = 10
x - 2 + 2 = 10 + 2
x = 12
x + 6 = 13
x + 6 - 6 = 13 - 6
x = 7

y = 3/5x + 5
y = -3/5x + 5
y = 3/5x - 5
y = -3/5x - 5
Answer:
y= 3/5x+5
Step-by-step explanation:
The y intercept is 5 and the graph is going upwards so it is a postive slope. If you look at at the graph from the y intercept point to point B you can see it goes up by 3 and right by 5 so the slope is 3/5. This makes the equation y=3/5x+5
How many solutions can be found for the equation 5x + 3(x − 1) = 10x − 2x − 3?
None

3. Two
4. Infinitely many
Answer:
4. Infinitely many
Step-by-step explanation:
5x + 3(x − 1) = 10x − 2x − 3
5x+3x-3=8x-3
5x+3x-8x=3-3

Find the distance from A to C across the gorge illustrated in the figure.
The distance from A to C is ___ feet.
Step-by-step explanation:
tan B = AC/BC
tan 35°= AC / 160
0.700 = AC /160
=> AC = 160 × 0.700
AC = 112.00
so, the distance from A to C is 112.00 feet
From the triangle given in the figure,
ΔACB is a right triangle.Measure of angle ABC = 35°Measure of adjacent side BC = 160 ftSince, adjacent side BC of the right triangle ACB is given and we have to find the opposite side AC of angle ABC,
Trigonometric ratio to be used → [tex]\text{tan}\theta = \frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
By substituting these values in the expression,
[tex]\text{tan}(35^{\circ}) = \frac{AC}{160}[/tex]
AC = 160[tan(35)°]
AC = 112.03 feet
Therefore, distance between A and C is 112.03 feet.

Answer:
Median.
Step-by-step explanation:
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half. In simple terms, it may be thought of as the "middle" value of a data set. For example, in the data set {1, 3, 3, 6, 7, 8, 9}, the median is 6, the fourth number in the sample. The median is a commonly used measure of the properties of a data set in statistics and probability theory.

According to a June 12 invoice, George's Grocery Store owes $11,250 to Crane Food Services. The sales terms are 5/10, 3/15, n/30. Find the cash discount if the invoice is
paid on June 26.
$328.75
$337.50
$445.80
$562.50
None of these choices are correct.
Answer:
$337.50
Step-by-step explanation:
Given that
The amount is $11,250
And, the sales terms are 5/10, 3/15, n/30
5/10 means if the payment is done within 10 days so 5% discount is given
3/15 means if the payment is done within 15 days so 3% discount is given
And, n/30 means the credit days for payment allowed is 30
Now the cash discount if the invoice is paid on June 20 is
= $11,250 × 3%
= $337.50

The school canteen charges Rs 42 for lunch and Rs 8 for milk for
each day. How much money do you spend in 5 days on these things? Write proper steps. State the property used.
Answer:
After 5 days buying lunch and milk at the canteen school, Rs 250 will be spent.
Step-by-step explanation:
Given that the school canteen charges Rs 42 for lunch and Rs 8 for milk for each day, to determine how much money do you spend in 5 days on these things, the following calculation must be performed, using the distributive property:
(42 + 8) x 5 = X
50 x 5 = X
250 = X
Therefore, after 5 days buying lunch and milk at the canteen school, Rs 250 will be spent.

the volume of 12 buckets is the same as the volume of 9 bottles. the total volume of 3 bottles and 5 buckets is 21.6 liters. what is the volume of 1 bucket?
Answer:
The volume of 1 bucket is 2.4 liters.
Step-by-step explanation:
We know that the volume of 12 buckets is the same as the volume of 9 bottles:
[tex] 12B = 9b [/tex]
[tex] B = \frac{9}{12}b = \frac{3}{4}b [/tex] (1)
Where B is for buckets and b is for bottles.
Also, that the total volume of 3 bottles and 5 buckets is 21.6 liters:
[tex] 5B + 3b = 21.6 [/tex] (2)
We can calculate the volume of 1 bucket by entering equation (1) into (2):
[tex] 5(\frac{3}{4}b) + 3b = 21.6 [/tex]
By solving for "b" we have:
[tex] b = \frac{21.6*4}{27} = 3.2 [/tex]
Now, the volume of 1 bucket is:
[tex] B = \frac{3}{4}b = \frac{3*3.2}{4} = 2.4 [/tex]
Therefore, the volume of 1 bucket is 2.4 liters.
