Step-by-step explanation:
A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 23.2 pounds and a standard deviation of 6.6 pounds. Step 2 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 65 people on this diet, what would be the standard deviation of the sampling distribution of sample means
Answer:
The standard deviation of the sampling distribution of sample means would be 0.8186.
Step-by-step explanation:
We are given that
Mean of population=23.2 pounds
Standard deviation of population=6.6 pounds
n=65
We have to find the standard deviation of the sampling distribution of sample means.
We know that standard deviation of the sampling distribution of sample means
=[tex]\frac{\sigma}{\sqrt{n}}[/tex]
Using the formula
The standard deviation of the sampling distribution of sample means
=[tex]\frac{6.6}{\sqrt{65}}[/tex]
[tex]=0.8186[/tex]
Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.

The amount of water dispensed by a water dispenser is normally distributed,
with a mean of 12.10 ounces and a standard deviation of 0.25 ounces. In
which range will the amount of water dispensed be found 95% of the time?
A. 11.85 ounces to 12.35 ounces
B. 11.35 ounces to 12.85 ounces
C. 11.60 ounces to 12.60 ounces
D. 11.10 ounces to 13.10 ounces
Answer:
C. 11.60 ounces to 12.60 ounces
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean 12.10, standard deviation 0.25.
In which range will the amount of water dispensed be found 95% of the time?
By the Empirical Rule, within 2 standard deviations of the mean. So
12.10 - 2*0.25 = 12.10 - 0.5 = 11.60
12.10 + 2*0.25 = 12.10 + 0.5 = 12.6
So the correct answer is given by option C.

Which equation has the following: Center (0, -3) and radius [tex]\sqrt{11}[/tex]
Answer:
The equation of the circle is [tex]x^2 + (y + 3)^2 = 11[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle with center [tex](x_0,y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
Center (0, -3)
This means that [tex]x_0 = 0, y_0 = -3[/tex]
Radius square root of 11
This means that [tex]r = \sqrt{11}[/tex]
Equation of the circle:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
[tex](x - 0)^2 + (y - (-3))^2 = (\sqrt{11})^2[/tex]
[tex]x^2 + (y + 3)^2 = 11[/tex]
The equation of the circle is [tex]x^2 + (y + 3)^2 = 11[/tex]
What is an equation of the line that passes through the points (8, -8) and (1, 6)?
Answer:
[tex]y=-2x+8[/tex]
Step-by-step explanation:
In slope-intercept form, the equation of a line is given by [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope of the line, [tex]b[/tex] is the y-intercept, and [tex](x,y)[/tex] represent the coordinates of any point the line passes through.
Since we're given two points the line passes through, we can find the slope of the line using the slope formula [tex]m=\frac{\Delta y}{\Delta x}[/tex]:
[tex]m=\frac{-8-6}{8-1}=\frac{-14}{7}=-2[/tex]
Now we can plug in any point the line passes through to find the y-intercept:
[tex]6=-2(1)+b,\\6=-2+b,\\b=8[/tex]
Thus, the equation of this line is equal to [tex]y=-2x+8[/tex].
A 12.5 oz bag of Doritos costs $3.79. A 3 oz bag costs $1.00. What is the difference in unit rates?
Answer:
0
Step-by-step explanation:
12.5/3.79 = 3.2981530343
3.2981530343 rounded = 3.3
1/3 = 3.33333333333333
3.33333333333333 rounded = 3.3
3.3 - 3.3 = 0
9514 1404 393
Answer:
$0.03 per ounce
Step-by-step explanation:
The unit rate for the smaller bag is ...
$1.00/(3 oz) = $0.333 /oz
For the larger bag, it is ...
$3.79/(12.5 oz) = $0.303 /oz
Then the difference in unit rates is ...
$0.333 -0.303 = $0.03 . . . per ounce

A sailor judges the distance to a lighthouse by holding a ruler at arm's length and measuring the apparent height of the lighthouse. He knows that the lighthouse is actually 60 feet tall. If it appears to be 3 inches tall when the ruler is held 2 feet from his eye, how far away is it?
9514 1404 393
Answer:
480 ft
Step-by-step explanation:
The geometry involves two similar triangles. The ruler at arms length forms a triangle that has the opposite side 3 inches high and 24 inches (2 ft) away. That is, the distance from the eye to the ruler is 8 times the height of the ruler.
The triangle involving the lighthouse is similar. That is, the angles in it are the same, so the sides are proportional to those in the smaller (ruler) triangle. The distance to the lighthouse will be 8 times the height of the lighthouse, just as the distance to the ruler is 8 times the height of the ruler.
8 × 60 ft = 480 ft
The lighthouse is 480 feet away.

Answer:
(i)
[tex] x \alpha y {3} \\ \frac{x}{y {3} } = k[/tex]
(ii)
[tex] \frac{x}{y {3}^{} } = \frac{x}{y {3}^{} } \\ \frac{32}{ {2}^{3} } = \frac{x}{6 {}^{3} } \\ \frac{32}{8} = \frac{x}{216} \\ x = 864[/tex]

If AABC ~ ADEF, what is the length of DE?
NEED HELP ASAP please and thanks In advance
Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21

Step-by-step explanation:
Red=40%
Green =x%
40/100 × 60apples
0.4×60
24red apples
so 60-24
36green apples
Answer:
b) 36.
Step-by-step explanation:
Justicemoya35 has an excellent answer, but I will provide a slightly different approach!
According to the word problem, the box contains 60 apples.
If 40% of the apples are red, then 60% of the apples are green.
As I mentioned before, there are 60 apples; 60% of the 60 apples are green.
This means we have the find 60% of 60.
We can find the percentage of a number by using this formula:
60% OF 60
[tex]\frac{is}{of} =\frac{percent}{100}[/tex]
[tex]\frac{x}{60} =\frac{60}{100}[/tex]
Now that I've correctly set up the problem, we cross multiply, then divide the products.
[tex]60*60=3600[/tex]
[tex]100*x=100x[/tex]
[tex]3600/100x=36[/tex]
[tex]x=36.[/tex]
Therefore, 36 apples are red.
The table below shows the probability distribution of student ages in a high school with 1500 students. What is the expected value for the age of a randomly chosen student? Age 13 14 15 16 17 18 Probability 0.01 0.27 0.30 0.25 0.16 0.01 O A. 15.38 OB. 15.31 O C. 15.50 D. 15.35 SUBNET
Answer:
According to me it should be Option B, 15.31
Hope this helps!
The expected value for the age of a randomly chosen student is,
⇒ 15.38
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that:
Total number of students,
⇒ n = 1500,
And, Age : 13, 14, 15, 16, 17, 18
Probability : 0.01, 0.25, 0.27, 0.30, 0.16, 0.01
Now,
We can Calculate the expected value as shown below,
E = 13 × 0.01 + 14 × 0.25 + 15 × 0.27 + 16 × 0.30 + 17 × 0.16 + 18 × 0.01
E = 0.13 + 3.5 + 4.05 + 4.8 + 2. 72 + 0.18
E = 15.38
Therefore, The expected value for the age of a randomly chosen student is 15.

I am thinking of a number.i add 62 to the number and divide the total by 7.the result is 4 less than the number 1 thought of.what was the number
Answer:
15
Step-by-step explanation:
let the number be n, then
[tex]\frac{n+62}{7}[/tex] = n - 4 ( multiply both sides by 7 to clear the fraction )
n + 62 = 7n - 28 ( subtract n from both sides )
62 = 6n - 28 ( add 28 to both sides )
90 = 6n ( divide both sides by 6 )
15 = n
That is the number is 15
