Answer:
The answer is "0.43"
Step-by-step explanation:
Population proportion normal distribution is suggested as following:
Confidence Interval = [tex]P \pm Z \times \sqrt{\frac{P \times (1 -p)}{n} }[/tex]
Confidence Interval = [tex]P \pm E[/tex]
Bottom bound [tex]= P-E = 0.23[/tex]
Lower bound [tex]= P + E = 0.63[/tex]
Through connecting additional formulas, we're getting,
[tex]\to 2P = 0.23+0.63\\\\\to 2P = 0.86\\\\\to P= \frac{0.86}{2}\\\\[/tex]
[tex]= 0.43[/tex]
The average with all attribute outcomes a whereby the demographic proportion at 5 % isn't dismissed as plausible values is 0.43.

The temperature of liquid in an experiment starts at 0*C. The experiment calls for the temperature of the liquid to change at a rate of -0.60*C per minute. How long will it take for the liquid to reach -10.5*C
Answer:
The liquid will take 17.5 minutes to reach -10.5 ºC.
Step-by-step explanation:
From this statement we understand that the temperature of liquid is increased at constant rate in time, whose model is described by:
[tex]T (t) = \dot r \cdot t + T_{o}[/tex] (Eq. 1)
Where:
[tex]T[/tex] - Temperature of the liquid, measured in degrees Celsius.
[tex]\dot r[/tex] - Heating rate, measured in degrees Celsius per minute.
[tex]t[/tex] - Time, measured in minutes.
[tex]T_{o}[/tex] - Initial temperature, measured in degrees Celsius.
If we know that [tex]\dot r = -0.60\,\frac{^{\circ}C}{min}[/tex] and [tex]T_{o} = 0\,^{\circ}C[/tex], the temperature model for the liquid is:
[tex]T(t) = -0.60\cdot t[/tex] (Eq. 2)
In addition, if [tex]T(t) = -10.5\,^{\circ}C[/tex], then time taken for the liquid to reach that temperature is:
[tex]t = \frac{-10.5}{-0.60}[/tex]
[tex]t = 17.5\,min[/tex]
The liquid will take 17.5 minutes to reach -10.5 ºC.

A population of bears is decreasing the population this year is 200 bears after 1 year it is estimated that the population will be 160 bears after 2 years it is estimated that the population will be 128 bears what equation describes the bear population in any year x?
Answer:
The equation is;
y = 200•0.8^x
where y is the number of bears remaining and x is the year number in particular
Step-by-step explanation:
Let us have the rate of decrease as r and we set up an exponential equation
y = I• ( 1 - r)^x
where r is the percentage decrease, I is the initial population = 200 and x is the number of years
For the population after 1 year, we have;
160 = 200( 1 -r)^x
divide both sides by 200
0.8 = (1-r)^1
0.8 = 1 - r
r = 1 - 0.8
r = 0.2
So the equation will be;
y = 200( 1 - 0.2)^x
y = 200•0.8^x

Hich statements about the function f are true? Check all that apply. The domain of f(x) is {all real numbers}. The range of f(x) is {all real numbers}. The domain of f(x) is {x| x > 0}. The range of f(x) is {y| y > 0}. f(2) = 4 f(2) = 2(x + 3)
Answer:
A. The domain of f(x) is {all real numbers}.
B. The range of f(x) is {all real numbers}
E. f(2) = 4
Explanation
Find the graph attached.
The domain of a function is the value of the input variable x for which the function f(x) exists. Given the function
f(x) = 1/2 x + 3
The function will exist on all values of x (either positive or negative).
The domain can be said to exist on all real values. If you look at the graph, we will see that the line tends to both negative infinity and positive infinity. Hence the domain can be represented according to the set notation:
DOMAIN: (-∞, ∞)
The range is the set of output value y for all input variable x. The output value y will also exist on all real values because, no matter the value of x imputed in the function, we will always get a finite value as the output. Hence the range of the function is denoted by the set notation:
RANGE: (-∞, ∞)
Next is to get f(2).
To get f(2), we will set the input value as 2 and calculate for the output value as shown:
f(2) = 1/2(2) + 3
f(2) = 1+3
f(2) = 4
Hence the following are true of the function:
The domain of f(x) is {all real numbers}.
- The range of f(x) is {all real numbers}
- f(2) = 4

A certain brand of laundry detergent comes in two sizes. The smaller size is 24 oz and cost $3.99. The larger size is 64 oz and cost $6.99. Which has the lower unit cost?
Given:
The smaller size is 24 oz and cost $3.99.
The larger size is 64 oz and cost $6.99.
To find:
Which has the lower unit cost?
Solution:
The formula for unit cost is
[tex]\text{Unit cost}=\dfrac{\text{Total cost}}{\text{Quantity}}[/tex]
The unit cost of smaller size is
[tex]\text{Unit cost of smaller size}=\dfrac{3.99}{24}[/tex]
[tex]\text{Unit cost of smaller size}=0.16625[/tex]
The unit cost of larger size is
[tex]\text{Unit cost of larger size}=\dfrac{6.99}{64}[/tex]
[tex]\text{Unit cost of larger size}=0.10922[/tex]
It is clear that, 0.10922 is less than 0.16625.
Therefore, the unit cost of larger size is lower.
60 students
Solve for v in this equation:
3 teachers
15 teachers
Answer:
V would be equivalent to 300 students
Step-by-step explanation:
Noting that 3 teachers already have 60 students
If we're given 15 teachers, try dividing it by the 3 teachers that we originally have.
15/3 would be 5
We would now proceed to multiply the 60 students by 5 for the total amount of students with 15 teachers.
60*5 would be 300
Your answer should be 300 students.

The Miami Heat scored 79 points. This was 13 points less than the Chicago Bulls. How many points did the Chicago Bulls score?
Write an equation and solve.
Answer:
92
Step-by-step explanation:
Miami scored 79 points which was 13 LESS than Chicago.
So, Miami = Chicago - 13, (change Miami to their score)
79 = Chicago - 13 (add 13 to both sides to isolate Chicago and find answer)
92 = Chicago
Equation: 79 = Chicago - 13

in triangle DEF, the measure of angle Eis 30 and the measure of angle F is 45. What is the measure of angle D?
Answer:
angke D = 105°
Step-by-step explanation:
All triangles add up to 180°. 30+45=75 180-75=105
In triangle DEF, the measure of angle D is 105°.
What is a triangle?A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.
The sum of the angles of a triangle is always 180°
Given that,
In triangle DEF,
Value of ∠ E = 30°, ∠ F = 45°.
Let the value of ∠ D is x°.
Since, the sum of the angles of a triangle is 180°.
Apply this property in triangle DEF,
30 + 45 + x = 180
75 + x = 180
x = 180 - 75
x = 105
The value of ∠ D is 105°.
