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.

Mia, an accountant, observes that her company purchased softball bats at a cost of $14 and
is currently selling them at a price of $21. What percentage is the mark-up?
Write your answer using a percent sign (%).
5%
(Markup percent/100) × Cost price = Selling price - cost price
=> (Markup percent/100) × $14 = $21 - $14
=> (Markup percent/100) × $14 = $7
=> (Markup percent/100) = $7 / $14
=>

Step-by-step explanation:
It can be useful to write down the values of corresponding parts of the figures. This can help you see the ratio between corresponding measures. Here, we're concerned with sides.
AB = ?, FE= 6
BC = 10, EC = 5 . . . . . a ratio of 2:1
CD = ?, CG = ?
DA = y, GF = 4
So, the proportionality of the sides in these similar figures means ...
y/4 = 10/5
y = 4×10/5
y = 8 . . . . multiply by 4

If the total area of a dartboard is 804 in2 and the area of the bull's-eye is 50in2, what is the probability that a dart that randomly hits the dartboard will hit the bull's-eye?
Answer:
6.2%, option A.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
The desired area to hit is of 50 in², while the total area is of 804 in². Thus, the probability of hitting the bull's-eye is:
[tex]p = \frac{50}{804} = 0.062[/tex]
0.062*100% = 6.2%.
6.2%, option A.

Neglecting air resistance and the weight of the propellant, determine the work (mi-tons) done in propelling a four-metric-ton satellite to a height of 220 miles above Earth. (Use 4,000 miles as the radius of Earth. Round your answer to two decimal places.)
Answer:
the work done in propelling the satellite is 919.2 mile-tons
Step-by-step explanation:
Given the data in the question;
we know that, the weight of a body varies inversely as the square of its distance from center of of earth;
⇒ F(x) = c / x²
given that F(x) = four-metric-ton = 4 × 1.102 = 4.408 tons
radius of earth = 4000 miles
we substitute
⇒ 4.408 = c / ( 4000 )²
c = 4.408 × ( 4000 )² = 70528000
so increment of work will be;
ΔW = ( 70528000 / x² ) Δx
Now work done in propelling to a height of 220 miles above Earth;
W = ₄₀₀₀∫⁴²²⁰ ( 70528000 / x² ) dx
W = 70528000[ - 1/x ]⁴²²⁰₄₀₀₀
W = 70528000[ - 1/4220 + 1/4000 ]
W = 70528000[ 1.3033175 × 10⁻⁵ ]
W = 919.2 mile-tons
Therefore, the work done in propelling the satellite is 919.2 mile-tons

Noah invests $3,600 for two years.
The account pays 0.43% monthly compound interest. To the nearest cent, what's the total that will be in Noah's account after two years?
Answer:
Future value, A = $8444.16
Step-by-step explanation:
Given the following data;
Principal = $3,600
Time = 2 years
Number of times = 24
Interest rate = 0.43 %
To find the future value, we would use the compound interest formula;
[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]
Where;
A is the future value. P is the principal or starting amount. r is annual interest rate. n is the number of times the interest is compounded in a year. t is the number of years for the compound interest.Substituting into the equation, we have;
[tex] A = 3600(1 + \frac{0.43}{24})^{24*2}[/tex]
[tex] A = 3600(1 + 0.01792)^{48}[/tex]
[tex] A = 3600(1.01792)^{48}[/tex]
[tex] A = 3600(2.3456)[/tex]
Future value, A = $8444.16

Step-by-step explanation:
While visiting the Albert Michelson exhibit at Clark University, you notice that a chandelier (which looks remarkably like a simple pendulum) swings back and forth in the breeze once every
T = 6.2 seconds.Randomized VariablesT = 6.2 seconds(a) Calculate the frequency of oscillation (in Hertz) of the chandelier.(b) Calculate the angular frequency ω of the chandelier in radians/second.
(c) Determine the length L in meters of the chandelier. sig.gif?
(d) That evening, while hanging out in J.J. Thompson’s House O’ Blues, you notice that (coincidentally) there is a chandelier identical in every way to the one at the Michelson exhibit except this one swings back and forth 0.11 seconds slower, so the period is T + 0.11 seconds. Determine the acceleration due to gravity in m/s2 at the club.
Answer:
a) [tex]F=0.16Hz[/tex]
b) [tex]\omega=1rad/s[/tex]
c) [tex]L=9.54m[/tex]
d) [tex]g=9.46m/s^2[/tex]
Step-by-step explanation:
From the question we are told that:
Time [tex]T =6.2[/tex]
a)
Generally the equation for Frequency F is mathematically given by:
[tex]F=\frac{1}{T}[/tex]
[tex]F=\frac{1}{6.2}[/tex]
[tex]F=0.16Hz[/tex]
b)
Generally the equation for Frequency F is mathematically given by:
[tex]\omega=2\pi f[/tex]
[tex]\omega=2*314* 0.16[/tex]
[tex]\omega=1rad/s[/tex]
c)
Generally the equation for Length of Chandelier L is mathematically given by:
Since
[tex]T=2*3.142\sqrt{\frac{L}{g}}[/tex]
Therefore
[tex]L=\frac{gT^2}{4 \pi^2}[/tex]
[tex]L=\frac{9.8*(6.2)^2}{4 \pi^2}[/tex]
[tex]L=9.54m[/tex]
d)
Since
Michelson exhibit except this one swings back and forth 0.11 seconds slower
Therefore
[tex]T'=T+0.11[/tex]
[tex]T'=6.31[/tex]
Generally the equation for acceleration due to gravity g is mathematically given by:
[tex]g = \frac{4\pi ^2L}{( T')}^2[/tex]
[tex]g = \frac{4\pi ^2L\*9.54}{( 6.31 s )}^2[/tex]
[tex]g=9.46m/s^2[/tex]

Answer:
c. 17
Step-by-step explanation:
So the equation is 3g = 51.
What we are given is {15, 16, 17}
Let's plug in each of these into the equation for g.
3(15) = 51
45 = 51
45 does not equal 51.
3(16) = 51
48 = 51
48 does not equal 51
3(17) = 51
51 = 51
51 does equal to 51.
So 17 is your answer, because if you plug it into the equation, you get an equivalent answer of 51.

Describe how the graph of y= x2 can be transformed to the graph of the given equation. (2 points) y = (x-4)2-8
Answer:
The description is that the function was translated 4 units to the right and 8 units down.
Step-by-step explanation:
Translations:
Translating a function f(x) a units to the right is the same as finding f(x - a).
Translating a function f(x) a units to the left is the same as finding f(x + a).
Translating a function f(x) a units up is the same as finding f(x) + a.
Translating a function f(x) a units down is the same as finding f(x) - a.
y= x² to y = (x-4)²-8
First at the domain, x becomes x - 4, so f(x) becomes f(x - 4), that is, the function was translated 4 units to the right.
Then the function is subtracted by 8, that is, it was translated 8 units down.
The description is that the function was translated 4 units to the right and 8 units down.
