About 12% of children are nearsighted. A school district will be testing the vision of 170
incoming kindergarten children.
What proportion of these kids should we expect to be nearsighted (p-hat)?
Answer:
about 21 kids out of 170 are expected to be nearsighted (20:170)
Step-by-step explanation:
we find 12% out of 70 by muliplying 170 x 0.12 which equals 20.4
However it has to round up because we cant have half a child so 21 children.
Answered What is the mean for the set of data? 6, 7, 10, 12, 12, 13
Answer:
10
Step-by-step explanation:
The mean for the set of data 6, 7, 10, 12, 12, and 13 is 10.
What is arithmetic mean?The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
Given the set of observations as:
{6, 7, 10, 12, 12, 13}
To determine the mean of a set of data, add up all the numbers and divide by the total number of numbers.
So, for the given set of data:
Mean = (6 + 7 + 10 + 12 + 12 + 13) / 6
Mean = 60 / 6
Mean = 10
Therefore, the mean for the given set of data is 10.

Do 1.7 and 1.700 have the same value? In a full sentence, explain why or why notw
Answer: Yes
1.7 and 1.700 have the same value because zeros have no value, and without the zeros, 1.700 would turn into 1.7. It is not like there is another number that is not zero after the two zeros either.

6. The temperature in a city on a Friday was 46.8 degrees Fahrenheit. On Saturday, the temperature was 63.5 degrees Fahrenheit. How much higher was the temperature on Saturday?
Answer:16.7
Step-by-step explanation:subtract 63.5 by 46.8 and you will get 16.7 degrees fahrenheit
If Friday and Saturday have such a temperature of 46.8 and 63.5 degrees Fahrenheit, respectively. Saturday's temperature is 16.7 degrees Fahrenheit lower than Friday's.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that the temperature in a city on a Friday was 46.8 degrees Fahrenheit. On Saturday, the temperature was 63.5 degrees Fahrenheit.
The temperature on Saturday is how much less than the temperature on Friday found as,
= 63.5 - 46.8
= 16.7° F
Thus, If Friday and Saturday have such a temperature of 46.8 and 63.5 degrees Fahrenheit, respectively. Saturday's temperature is 16.7 degrees Fahrenheit lower than Friday's.

. Explain the difference between a discrete variable and a continuous variable. Choose the correct answer below. A. A discrete variable has observed values that are clustered in certain intervals, while a continuous variable has observed values that are evenly distributed throughout the distribution. B. A discrete variable has possible values that are separate numbers, while a continuous variable has possible values that form an interval. C. A discrete variable has infinitely many possible values, while a continuous variable is usually a count. D. A discrete variable has each observation belong to one of a set of distinct categories, while a continuous variable has observations that take numerical values that represent different magnitudes of the variable.
Answer:
The correct answer is:
A discrete variable has possible values that are separate numbers, while a continuous variable has possible values that form an interval. (B)
Step-by-step explanation:
There are two major categories of variables in data measurement: Discrete and Continuous variables
A Discrete variable is a type variable that can take on a distinct number, obtained by counting, and there is a limit to the value that that variable can take on. An example is the number of students in a class. This can be 10, or 20 or 25, etc. There cannot be 12.8 students or 13.1 students. Hence this kind of variable is a discrete variable.
A Continuous variable is one that is measured and not counted. they have an infinite possibility within a range in a scale of measurement. An example is; the height of trees in meters. The possibilities can be 3.6m, 4.08m, 5m, 1.9m, etc. There is no distinct number, but a possibility of ranges.

A lake initially contains 3000 fish. Suppose that in the absence of predators or other causes of removal, the fish population increases by 7% each month. However, factoring in all causes, 300 fish are lost each month. How many fish will be in the pond after 5 months
Answer:
2,482 fishes will be in the pond after 5 months
Step-by-step explanation:
First, let us model an equation that is used to determine the fish population after n months:
Let the initial population of the fishes = P₀
Let the population after n months = Pₙ
percentage increase each month = 7%
[tex]P_n = P_{n-1} + 7 \%P_{n-1}\\P_n = P_{n-1} + 0.07P_{n-1}\\P_n = (1.07)P_{n-1}[/tex]
Next, we are told that 300 fishes are lost each month, therefore, the population after n months is given by:
[tex]P_n = (1.07)P_{n-1} - 300[/tex]
Therefore population after 5 months:
n = 5
[tex]P_5 = (1.07)P_{5-1} - 300\\P_5 = (1.07)P_4 - 300[/tex]
[tex]Remember\ P_0 = 3000\\starting\ at\ P_1\\P_1 = (1.07)P_0 - 300\\P_1 = (1.07)(3000) - 300\\P_1 = 3210 - 300 = 2910\\P_2 = (1.07)P_1 - 300\\P_2 = (1.07)(2910) - 300 = 2813.7\\\\P_3 = (1.07)(2813.7) - 300\\P_3 = 3010.66 - 300 = 2710.66\\\\P_4 = (1.07)(2710.66) - 300 = 2600.40\\\\P_5 = (1.07)(2600.40) - 300 = 2482.4\\[/tex]

We roll two dice. Find the conditional probability that at least one of the numbers is even, given that the sum is 8.
Answer:
0.599 or 0.6
Step-by-step explanation:
We will be using the alphabets M and N in this solution.
Let M be that one of the number is even
Let N be that the sum is 8
The sample space of these two dice when rolled is 36
Probability of 8 and even numbers is (4,4),(6,2),(2,6)
= 3/36 = 0.08333
Probability of sum of 8 is (4,4),(5,3)(3,5),(6,2),(2,6)
= 5/36 = 0.1389
P(M|N) = 0.08333/0.1389
= 0.599

A 33 % dextrous solution ( 33 mg per 100 mL of solution) is given intravenously. Suppose a total of 1.936 L of the solution is given over a n 11-hour period. Complete parts (a) through (c) below.
what is the flow rate in units of ml/hr?
mL/hr (Type an integer or decimal rounded to the nearest thousandth as needed.)
What is the flow rate in per hour?
nothing mg/hr (Type an integer or decimal rounded to the nearest thousandth as needed.)
b. If each mL contains 16 drops (the drop factor is expressed as 16 gtt/mL), what is the flow rate in units of gtt/hr?
nothing gtt/hr (Type an integer or decimal rounded to the nearest thousandth as needed.)
c. During the 11 -hour period, how much is delivered?
nothing mg (Type an integer or decimal rounded to the nearest thousandth as needed.)
Answer:
[tex]176\ \text{ml/hr}[/tex]
[tex]58.08\ \text{mL/hr}[/tex]
[tex]11\ \text{gtt/hr}[/tex]
[tex]638.88\ \text{mg}[/tex]
Step-by-step explanation:
33 % dextrous solution ( 33 mg per 100 mL of solution)
1.936 L of the solution is given over an 11-hour period
So the flow rate in mL/hr is
[tex]\dfrac{1.936\times 10^3}{11}=176\ \text{ml/hr}[/tex]
The flow rate in ml/hr is [tex]176\ \text{ml/hr}[/tex]
Flow rate of dextrous in mL/hr is
[tex]0.33\times 176=58.08\ \text{mL/hr}[/tex]
The flow rate dextrous in mL/hr is [tex]58.08\ \text{mL/hr}[/tex]
Each mL contains 16 drops so flow rate in gtt/h is
[tex]\dfrac{176}{16}=11\ \text{gtt/hr}[/tex]
The flow rate in units of gtt/hr is [tex]11\ \text{gtt/hr}[/tex]
The mass of dextrous delivered 11 hours in mg is
[tex]0.33\times 1.936\times 10^3=638.88\ \text{mg}[/tex]
The mass of dextrous delivered 11 hours in mg is [tex]638.88\ \text{mg}[/tex]
Let A, B, and C be any sets with A ⊆ C and B ⊆ C. Show that A – B = A ∩ (C – B).
Can you help me prove the proof holds true?
I assume A - B is the complement of B in A, i.e. all elements of A that do not belong to B.
To prove equality between two sets, you have to show they are subsets of one another. To prove one set is a subset of another set, you have to show that any element in the first set belongs to the second set.
So, to show that A - B = A ∩ (C - B), you have to prove
• A - B ⊆ A ∩ (C - B)
• A ∩ (C - B) ⊆ A - B
Left to right:
Let x ∈ A - B.
By definition of set complement, x ∈ A and x ∉ B.
Since A ⊆ C, x ∈ C.
So x ∈ C - B, and by definition of set intersection, x ∈ A ∩ (C - B).
This proves A - B ⊆ A ∩ (C - B).
Right to left:
Let x ∈ A ∩ (C - B).
By definition of set intersection, x ∈ A and x ∈ C - B.
By definition of set complement, x ∈ C and x ∉ B.
Again by definition of complement, x ∈ A and x ∉ B means that x ∈ A - B.
This proves A ∩ (C - B) ⊆ A - B.
Both sets are subsets of one another, so A - B = A ∩ (C - B).

Step-by-step explanation:
Count the number of outcomes from the coin toss. There are 2: heads or tails.
For each of those, there are 3 outcomes from the marble pick: R, Y, G. So the tree up to this point has 2·3 = 6 leaves:
head - R
head - Y
head - G
tail - R
tail - Y
tail - G
__
For each of these 6 outcomes so far, spinning the spinner will add 4 more. That will bring the total of possible outcomes to ...
2 × 3 × 4 = 24 . . . outcomes
The short answer is that the total number of outcomes is the product of the numbers of possibilities at each stage.
