Suppose Company A produces packages of throat lozenges that are normally distributed with a mean of 38.2 individual lozenges and a standard deviation of 1.7 lozenges.
Company B produces packages of throat lozenges that are normally distributed with a mean of 36.9 individual lozenges and a standard deviation of 2.4 lozenges.
Select from the drop-down menus to correctly complete the statement.
CHOICES ARE COMPANY A AND COMPANY B
Answer: B, A, B
Step-by-step explanation:
Let's find the z-score for both companies using the formula: [tex]z=\dfrac{x-\mu}{\sigma}[/tex]
Company A: [tex]z=\dfrac{43-38.2}{1.7}=\large\boxed{2.8}[/tex]
Company B: [tex]z=\dfrac{43-36.9}{2.4}=\large\boxed{2.5}[/tex]
The z-score from Company B is closer to 0 than the z-score of Company A so it it more likely that a package of 43 lozenges is produced by Company B
Since the z-score from Company A is closer to zero than the z-score of Company B, the company that produced a package with 43 lozenges in it is most likely Company A.
To find which company is more likely to produce a package with 43 lozenges, we'll first calculate the z-scores for each company using the formula:
[tex]\[ z = \frac{x - \mu}{\sigma} \][/tex]
Where:
- [tex]\( x \)[/tex] is the number of lozenges in the package (43)
- [tex]\( \mu \)[/tex] is the mean number of lozenges in the package for each company
- [tex]\( \sigma \)[/tex] is the standard deviation of the number of lozenges in the package for each company
For Company A:
[tex]\[ z_A = \frac{43 - 38.2}{1.7} = \frac{4.8}{1.7} \approx 2.82 \][/tex]
For Company B:
[tex]\[ z_B = \frac{43 - 36.9}{2.4} = \frac{6.1}{2.4} \approx 2.54 \][/tex]
Since the z-score for Company A (2.82) is higher than the z-score for Company B (2.54), it indicates that the value of 43 lozenges is relatively further away from the mean for Company A compared to Company B.
Thus, Company A is more likely to produce a package with 43 lozenges.
The correct question is:
Suppose Company A produces packages of throat lozenges that are normally distributed with a mean of 38.2 individual lozenges and a standard deviation of 1.7 lozenges.
Company B produces packages of throat lozenges that are normally distributed with a mean of 36.9 individual lozenges and a standard deviation of 2.4 lozenges.
Select from the drop-down menus to correctly complete the statement.
Since the [tex]$z$[/tex]-score from [tex]$\square$[/tex] is closer to zero than the [tex]$z$[/tex]-score of [tex]$\square$[/tex] , the company that produced a package with 43 lozenges in it is most likely [tex]$\square$[/tex] .

If the coordinates of point A are (8 , 0) and the coordinates of point B are (3 , 7), the y-intercept of is . If the coordinates of point D are (5 , 5), the equation of line is y = x + .
Answer with explanation:
Equation of line Passing through two points (a,b) and (c,d) is given by:
[tex]\frac{y-b}{x-a}=\frac{d-b}{c-a}[/tex]
Equation of line Passing through two points (8,0) and (3,7) is given by:
[tex]\rightarrow \frac{y-7}{x-3}=\frac{7-0}{3-8}\\\\\rightarrow \frac{y-7}{x-3}=\frac{7}{-5}\\\\\rightarrow -5 y+35=7 x - 21\\\\\rightarrow 5 y= -7 x +35 +21\\\\ y=\frac{-7 x}{5}+\frac{56}{5}\\\\y=-1.4 x +11.2[/tex]
Comparing with slope intercept form of line,
y= m x+c, where , m is slope and c is y intercept.
⇒Y intercept = 11.2
Equation of line Passing through two points (5,5) and (3,7) is given by:
[tex]\rightarrow \frac{y-7}{x-3}=\frac{7-5}{3-5}\\\\y-7= -1 \times (x-3)\\\\y=7-x+3\\\\y=-x +10[/tex]
Comparing with slope intercept form of line,
y= m x+c, where , m is slope and c is y intercept.
⇒Y intercept = 10
Equation of line is, y= -x +10.
The y-intercept of the line passing through point A (8, 0) and B (3, 7) is 56/5. The equation of the line that passes through these points and point D (5, 5) is y = (-7/5)x + (56/5).
To determine the y-intercept and the equation of a line, we first need to find the slope of the line. The slope (m) is given by the rise over run, which can be calculated using the coordinates of two points on the line. We have point A with coordinates (8, 0) and point B with coordinates (3, 7). The slope is therefore:
m = (Y2 - Y1) / (X2 - X1) = (7 - 0) / (3 - 8) = 7 / (-5) = -7/5
Now, we use the slope-intercept form of a line equation, which is y = mx + b, where b is the y-intercept. We can determine b by substituting the slope and the coordinates of one of the given points (we'll use point A). So:
0 = (-7/5)(8) + b
b = (7/5)(8) = 56/5
Therefore, the y-intercept is 56/5.
Knowing point D with coordinates (5, 5) is also on the line, we can use our slope m and this point to write the equation of the line:
y = (-7/5)x + (56/5)
However, since we know point D lies on this line, we can check if our equation is correct by substituting x = 5 and seeing whether y = 5:
5 = (-7/5)(5) + (56/5)
5 = -7 + 56/5
5 = 5
This confirms that our calculated equation is indeed correct and passes through all given points.

If there are initially 5000bacteria in a culture,and the number of bacteria doubles each hour,the number N of bacteria after t hours can be found using the formula N = 5000 [2 t ^]. About how long will it take the culture to grow to 40000 bacteria?
Answer:
3 hours
Step-by-step explanation:
3 hours as it takes 3 periods to be 40000
If there are initially 5000 bacteria in a culture,and the number of bacteria doubles each hour. The culture will take around 3 hours to reach 40,000 bacteria.
What is bacteria?To determine how long it will take for the culture to grow to 40,000 bacteria, we can use the given formula: N = 5000 * (2^t), where N represents the number of bacteria after t hours.
Substitute N with 40,000 and solve for t:
40,000 = 5000 * (2^t)
Divide both sides by 5000:
8 = 2^t
Since 2^3 = 8 we can conclude that t is equal to 3
Therefore it will take approximately 3 hours for the culture to grow to 40,000 bacteria.

4. Q(5, -6) and R(-5, 6)
Step-by-step explanation:
In the coordinates of point P which is (-5,-6) when you reflect it on the Y axis that means that the Y would be the same but the X will change signs, thats why the point Q is (5.-6) and to reflect it on the X axis the X remains the same but the Y would change the sign this is why point R will be (-5,6).
So point Q is (5,-6) and point R is (-5,6).

Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x-3y=13 4x-y=-9
2x -3y = 13
4x -y = -9
Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.
4x -y = -9 x -3 = -12x + 3y = 27
Now add this to the first equation:
2x -12x = -10x
-3y +3y = 0
13 +27 = 40
Now you have :
-10x = 40
Divide each side by -10:
x = 40 / -10
x = -4
Now you have a value for x, replace that into the first equation and solve for y:
2(-4) - 3y = 13
-8 - 3y = 13
Add 8 to both sides:
-3y = 21
Divide both sides by -3:
y = 21/-3
y = -7
Now you have X = -4 and y = -7

The length of a rectangle, I, is six meters more than it's width, w. If the perimeter of the rectangle is 36 meters what is the length of the rectangle, in meters
Answer:
Length = 12 meters
Step-by-step explanation:
Rectangle
Perimeter P = 2(L + W)
The length of a rectangle, I, is six meters more than it's width, W.
Then L = W + 6
So
P = 2(W + 6 + W)
P = 2 (2W + 6)
P = 4W + 12
Plug in P = 36 meters
36 = 4W + 12
4W = 36 - 12
4W = 24
W = 6 meters
L = 6 + 6
L = 12 meters
Amber is on a family cell phone plan with 2 other family members. The family gets 720 shared cell phone minutes a month, each family is limited to his or her equal fair share of minutes each month and calls between family members cost zero minutes. How many minutes per day does Amber have to call her friends without going over her monthly minutes if there are 30 days in that month?
Amber plus 2 family members = 3 total people on the plan.
They share the minutes equally so divide the minutes by 3 to find how many she can use:
720 / 3 = 240 minutes per month.
Now divide the monthly minutes by 30 days:
240 / 30 = 8 minutes per day.
Using the DMS method to describe an angle, one degree of angle measurement can be divided into how many minutes?
Answer:
1 degree = 60 minutes
Step-by-step explanation:
The DMS method is for Degree Minutes Seconds. That allows you to give a precise location the way it's most commonly used on paper maps. Today, with the electronic maps we mostly use the numeric version (34.234 degrees for example).
So, in the DMS method, one degree is basically like an hour on your clock. It can be divided into 60 minutes. Then, those minutes can be divided into 60 seconds. Just like an hour, a degree has 60 minutes and 3600 seconds.
Final answer:
One degree in the DMS method of angle measurement is divided into 60 minutes. To convert DMS to DD, like with 118 degrees 15 minutes, divide the minutes by 60 and add the result to the degrees, giving you 118.25.
Explanation:
In the DMS method of angle measurement, one degree is equivalent to 60 minutes of angle. This is similar to how an hour of time is divided into 60 minutes. To visualize this, if you consider a full circle being 360 degrees, each degree can be further subdivided into 60 smaller parts, each of these parts is known as a minute of angle.
For example, the conversion of 118 degrees 15 minutes to decimal degrees (DD) is a simple mathematical process. You would divide the minutes by 60 since there are 60 minutes in a degree, resulting in the equation 118 + 15/60, which equals 118.25 degrees. This conversion is an important skill in coordinate conversion activities, where positions are described in DMS format and need to be converted to DD for calculations.

Using the sine function sin Ф = --------
hyp
we find the length of the hypotenuse, which is also the radius of the octagon, and because this is an equilateral triangle, is also the length of the base:

sin 60° = -------- = ------------- , which produces the value of hyp:
2 hyp
√3 5√3 cm
-------- = ------------- , which produces the value of hyp:

in the 1980s, an average mortgage range was around 18.75%. how much less per month would a $125,000 30 year mortgage be today if the current rate were 5%?
Answer:
$1289.48
Step-by-step explanation:
A financial calculator tells you the payment with the higher interest rate is $1960.51, and that with the lower interest rate is $671.03. The difference in payment amounts is ...
$1960.51 -671.03 = $1289.48
Answer:
The current per month mortgages are $1289.54 less than the earlier per month mortgages.
Step-by-step explanation:
The EMI formula is = [tex]\frac{p\times r\times (1+r)^{n} }{(1+r)^{n}-1 }[/tex]
Here p = 125000
For case 1:
r = 18.75/12/100=0.015625
n = [tex]30\times12=360[/tex]
So, putting values in formula we get :
[tex]\frac{125000\times 0.015625\times (1+0.015625)^{360} }{(1+0.015625)^{360}-1 }[/tex]
= $1960.51
For case 2:
r = 5/12/100=0.004166
n = [tex]30\times12=360[/tex]
So, putting values in formula we get :
[tex]\frac{125000\times 0.004166\times (1+0.004166)^{360} }{(1+0.004166)^{360}-1 }[/tex]
= $670.97
Now we will find the difference between both EMI's
[tex]1960.51-670.97=1289.54[/tex] dollars.
Therefore, the current per month mortgages are $1289.54 less than the earlier per month mortgages.
