The red blood cell counts (in millions of cells per microliter) for a population of adult males can be approximated by a normal distribution, with a mean of 5.2 million cells per microliter and a standard deviation of 0.5 million cells per microliter. What is the minimum red blood cell count that can be in the top 24% of counts? What is the maximum red blood cell count that can be in the bottom 15% of counts? can somebody help me?
Answer:
5.55 million cells per microliter
4.68 million cells per microliter
Step-by-step explanation:
First, use a chart or calculator to find the z-score for reach percentage.
P(Z > z) = 0.24
P(Z < z) = 1 − 0.24 = 0.76
z = 0.706
Next, use definition of z-score to find the value.
z = (x − μ) / σ
0.706 = (x − 5.2) / 0.5
x = 5.55
Repeat for the other percentage.
P(Z < z) = 0.15
z = -1.036
z = (x − μ) / σ
-1.036 = (x − 5.2) / 0.5
x = 4.68

Answer:
6301.
Step-by-step explanation:
First we find the integer such that ? / 9 = 700.
? = 700 * 9 = 6300.
Therefore the least whole number for ? / 9 > 700 should be 6301.
How to find measurement of degree?
Answer:
It's 30 degrees. YSX and QSL are verticals so they are equal. Then QSL AND MLP are corresponding so they are too equal. So then yeah.
Answer:
30°
Step-by-step explanation:
It’s important to note the angle relationships.
We have two parallel lines intersecting one line. This means that each of the angles formed by one line will be equal to the angles formed by the other.
Using this info, we can tell that XYZ and MLP are alternate exterior angles, since they are formed by two parallel lines.
Alternate exterior angles are equal: since we know XYZ is 30°, MLP must be 30°.

Find all points on the x-axis that are 14 units from the point (6,-7) All points on the x-axis that are 14 units from the point (6, -7) are Simplify your answer. Type an ordered pair. Use a comma to separate answers as needed.)
Answer: [tex](6+7\sqrt{3},0)\text{ and }(6-7\sqrt{3},0)[/tex] are the required points.
or (18.124,0) and ( -6.124,0) are the required points.
Step-by-step explanation:
Let (x,0) be the point on x -axis that are 14 units from the point (6,-7) .
Then by distance formula , we have
[tex]\sqrt{(x-6)^2+(0-(-7))^2}=14\ \ \ [\ \because distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}][/tex]
Taking square on both the sides , we get
[tex](x-6)^2+7^2=14^2\\\\\Rightarrow\ x^2+6^2-2(6)x+49=196\\\\\Rightarrow\ x^2+36-12x=147\\\\\Rightarrow\ x^2-12x=111\\\\\Rightarrow\ x^2-12x-111=0[/tex]
Using quadratic formula : [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\dfrac{12\pm\sqrt{(-12)^2-4(1)(-111)}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{144+444}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{588}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm\sqrt{2^2\times7^2\times3}}{2}\\\\\Rightarrow\ x=\dfrac{12\pm14\sqrt{3}}{2}\\\\\Rightarrow\ x=6\pm7\sqrt{3}[/tex]
so, [tex](6+7\sqrt{3},0)\text{ and }(6-7\sqrt{3},0)[/tex] are the required points.
since [tex]\sqrt{3}=1.732[/tex]
so, [tex](6+7(1.732),0)\text{ and }(6-7(1.732),0)[/tex] are the required points.
i.e. (18.124,0) and ( -6.124,0) are the required points.
Draw a figure to represent the following information: T
is between S and U, ST = 7x, SU = 45, and TU = 5x –
3.
Answer:
ST = 28 unit
TU = 17 units
Step-by-step explanation:
Given:
ST = 7x
SU = 45
TU = 5x – 3
Find:
Each value
Computation:
SU = ST + TU
45 = 7x + 5x - 3
48 = 12x
x = 4
So,
ST = 7x
ST = 7(4)
ST = 28 unit
TU = 5x – 3
TU = 5(4) – 3
TU = 17 units
tristan wants to build a square garden in his backyard. if the garden is going to be 64 ft squared how many feet of material will he need for the perimeter of the garden?
Answer:
32 ft
Step-by-step explanation:
First Tristan must determine the length of one side of his square garden. Sine A = x^2, where x is the length of one side, and since 64 ft^2 = x^2, we can find the length x by taking the square root of both sides: 8 ft = x.
Now the length of the material enclosing the garden is the perimeter, P.
For a square, P = 4x.
Therefore, in this case, P = 4(8 ft) = 32 ft

There are 40 nickels in a roll. If you have 150 rolls of nickels, how many nickels do you have?
You would have 6,000 nickels. Multiply 40 by 150
There are 6000 Nickels in 150 rolls of Nickle.
To find out the total number of nickels you have, you need to multiply the number of nickels in a single roll by the number of rolls.
Given that there are 40 nickels in a roll and you have 150 rolls..
So, the total number of nickels can be calculated as:
= 40 nickels/roll x 150 rolls
= 6000 nickels.
Therefore, you have 6000 nickels.

The average hourly wage of computer programmers with 2 years of experience has been $21.80.Because of high demand for computer programmers,it is believed there has been a significant increase in the average wage of computer programmers.To test whether or not there has been an increase,the correct hypotheses to be tested area. H0: μ < 21.80 Ha: μ >= 21.80b. H0: μ = 21.80 Ha: μ ≠ 21.80c. H0: μ > 21.80 Ha: μ =< 21.80d. H0: μ <= 21.80 Ha: μ > 21.80
Answer:
d. H0: μ <= 21.80 Ha: μ > 21.80
Step-by-step explanation:
We set the null hypothesis as what is already given . We are already informed that the average wage is equal to μ <= 21.80 against the claim that is required. It is required to test whether the average wage of the computer programmers is greater than μ > 21.80
So option d is the best answer.
Hypotheses testing is done using an observation and a claim. The observation is set as a null hypothesis and claim is set as an alternative hypothesis. The null and alternative hypotheses must be chosen wisely to get the correct results.
The critical region is dependent on the claim set.
When Barbara started her trip, the odometer read 13,487.8. When she ended the trip, it read
14,108.6. Barbara's car gets 22 miles per gallon. Her tank was full at the beginning of the
trip. When she filled the tank, it cost her $88.04. How many gallons did Barb use, and what
price did she pay per gallon of gas on this fill-up?
HELP ASAP PLEASE
Answer:
28.2 gal
$3.12/gal
Step-by-step explanation:
Length of trip:
14,108.6 mi - 13,487.8 mi = 620.8 mi
(620.8 mi)/(22 mpg) = 28.218 gal
She used 28.2 gallons.
price per gallon = $88.04/(28.218 gal) = $3.12/gal

A company recently replaced its 9-oz cup of yogurt with a 7-oz cup and reduced the suggested retail price from 87 cents to 75 cents. Was the price per ounce reduced by the same percent as the size of the cup? If not, find the price difference per ounce in terms of a percent.
Answer:
Question 1
Was the price per ounce reduced by the same percent as the size of the cup? No it's not the same
Question 2
If not, find the price difference per ounce in terms of a percent.
13.8%
Step-by-step explanation:
The first yoghurt cup size = 9 oz
The second and recent yoghurt cup size = 7 oz
The difference in ounces = 9 oz - 7 oz
= 2 oz
Converting this difference to percentage
= 2 oz/ 9 oz × 100%
= 22.222222222%
The percent reduction in cup size is approximately
22.2%.
The first retail price per ounce = 87 cents
The second and recent retail price per ounce =75 cents
The difference in prices = 87 cents - 75 cents
= 12 cents
Converting this difference to percentage
= 12 cents / 87 cents × 100%
= 13.793103448%
The percent reduction in yoghurt price per ounce is approximately
13.8%.
Question 1
Was the price per ounce reduced by the same percent as the size of the cup?
From the above calculation,
Percent reduction in price per ounce =
13.8%
Percent reduction in the size of the cup = 22.2%
13.8% ≠ 22.2%
Therefore, it is not the same
Question 2
If not, find the price difference per ounce in terms of a percent.
Therefore, the price difference per ounce in terms of percent is
13.793103448%.
Approximately ≈ 13.8%
Open the line reflection application. The right line is a reflection across the y-axis of the left line. Click the reflect over y-axis button. Are these lines the same? What does this mean about how a line changes when you reflect it?
Answer:
The lines are the same, they are just in a different position.
Step-by-step explanation:
A reflection is a type of rigid transformation. Rigid transformations do not change the size nor the length of the pre-image.
In other words, the pre-image and the image in a rigid transformation are congruent.
Hope this helps.
Based on the fact that the right line is a reflection across the y-axis, the lines are the same, they are just in a different position.
What is a Reflection?This refers to the rigid transformation type that is used to represent an image and does not change its size or length of it.
With this understanding, we can see that the pre-image and the image in a rigid transformation are congruent which makes the lines to be the same, even if they are in a different position.
