Answer:
C
Step-by-step explanation:
Mean is the average. To find mean, add all the numbers in a data set, then divide by the number of values.
Example: 1,2,3,4,5
Mean: 1+2+3+4+5= 15
Number of values: 5
15/5 = 3
Mean is 3
A shipment of fibers is not acceptable if the mean breaking strength of the fibers is less than 50.03 N. A large sample of fibers from this shipment was tested, and a 98% lower confidence bound for the mean breaking strength was computed to be 50.1 N. Someone suggests using these data to test the hypotheses H0 : μ ≤ 50.03 versus H1 : μ > 50.03. Is it possible to determine from the confidence bound whether P < 0.01? Explain.
Answer:
NO it is not possible
Step-by-step explanation:
It is not possible to determine from the confidence bound whether p < 0.01 and this is because since the 50.03 is less than 98% lower confidence bound which is 50.1 N , we know that p value < 0.03 but P value might be ≥ 0.01 . hence we cannot determine from the confidence bound whether p < 0.01
(5 points) The population of a state changes due to births, deaths, and immigration. The annual birth rate is 14.3 births per 1000 residents, the death rate is 11.8 deaths per 1000 residents, the immigration rate into the state is 21.6 immigrations per 1000 residents, and the emigration rate out of the state is 5.5 emigrations per 1000 residents. Find the population growth rate as a percentage.
Answer:
The population growth rate is of 1.86%.
Step-by-step explanation:
Population growth rate:
Immigration plus births subtracted by emigration and deaths.
In this question, we have that:
Birth: 14.3 per 1000
Death: 11.8 per 1000
Immigrations: 21.6 per 1000
Emigrations: 5.5 per 1000
Rate:
[tex]\frac{14.3 + 21.6 - 11.8 - 5.5}{1000} = \frac{18.6}{1000} = 0.0186[/tex]
As a percentage:
Multiply by 100%. So
0.0186*100% = 1.86%
The population growth rate is of 1.86%.

Find the indicated area under the standard normal curve.
The total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is ___.
Answer:
0.1190
Step-by-step explanation:
If z = -1.18, the total area to the left under the standard normal curve is taken from the z-distribution table attached;
P(z < - 1.18) = 0.1190
Also, to the right of z = 1.18, we have;
P(z > 1.18) = 1 - P(z < 1.18)
From the second image attached from z-table, we have;
P(z > 1.18) = 1 - 0.8810
P(z > 1.18) = 0.1190
Thus, the total area to the left of z= - 1.18 and to the right of z= 1.18 under the standard normal curve is 0.1190

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
To find the area of the composite figure, which is not drawn to scale.
Now, The figure is made by a rectangle and a triangle.
We know that;
Area of rectangle = Lenght x Width
Hence, We get;
Area of rectangle = Lenght x Width
Area of rectangle = 22 x 17
Area of rectangle = 374 cm²
And, Area of triangle = 1/2 × Height × Base
⇒ Area of triangle = 1/2 × (22 - 10) × 19
⇒ Area of triangle = 1/2 × 12 × 19
⇒ Area of triangle = 114 cm²
Thus, Area of the composite figure, which is not drawn to scale is,
⇒ 374 + 114 cm²
⇒ 488 cm²

A
What is the volume of the cone?
Answer: 96 cubic units
Step-by-step explanation: I checked on Khan and that’s what they’re saying is the correct answer.
Answer:
The volume of the cone is 96 cubic unit.
Step-by-step explanation:
volume of squared based pyramid = (1/3) × (Base Area) × (Height).
96 [tex]unit^{3}[/tex] = (1/3)× 30×(Height)
9.6 unit = Height
volume of cone = (1/3) × (Base Area) × (Height).

A home seller wants to net $15,000. If he has agreed to pay a 5% commission, the loan payoff is $94,000 and closing costs are $16,000, what must the minimum listing price be? Round to the nearest $100.
9514 1404 393
Answer:
$131,600
Step-by-step explanation:
If the listing price is P, then the net is the difference between that and all of the various costs.
P -(5%×P) -94,000 -16000 = 15,000
0.95P = 125,000
P ≈ 131,600 . . . . . . divide by 0.95
The minimum listing price must be $131,600.

30) The sum of three consecutive numbers is 27. What are the three numbers? A. 8, 9, 10 B. 6, 7 8 C. 11, 12, 13 D. 9, 10, 11
Answer:
The answer is A. 8, 9, 10
Answer:
A. 8, 9, 10.
Step-by-step explanation:
Consecutive numbers counting numbers which are 1 greater than the other, therefore:
x + (x + 1) + (x + 2) = 27
(x + x + x) + (1 + 2) = 27
3x + 3 = 27
–3 –3
3x = 24
÷3 ÷3
x = 8.
x = 8 → [ x + (x + 1) + (x + 2) ] =
(8) + (8 + 1) + (8 + 2) = 8 + 9 + 10

This one takes time to type all the math work.
Let me see.
There are two triangles here.
They both have the same area.
A = (1/2)(base)(height) times 2
A = (1/2)(42)(56) times 2
A = 1,176 times 2
A = 2,352 inches^2.
We also have three rectangles. We need to find the area of each rectangle individually.
Area of bottom rectangle = 42 times 72 or 3,024 inches^2.
Area of back rectangle = 56 times 72 or 4,032 inches^2.
Area of slanted rectangle = 70 times 72 0r 5,040 inches^2.
We now add all the areas together to find the total area of the entire figure.
Total Area = 2,352 inches^2 + 3,040 inches^2 + 4,032 inches^2 + 5,040 inches^2
Total area = 14,448 inches^2

Given:

[tex]\dfrac{x-3}{x+2}+\dfrac{3x-3}{(x+1)(x+2)}=\dfrac{x}{x+1}-\dfrac{x-2}{x+2}[/tex]
To find:
The solution for the given equation.
Solution:
We have,
[tex]\dfrac{x-3}{x+2}+\dfrac{3x-3}{(x+1)(x+2)}=\dfrac{x}{x+1}-\dfrac{x-2}{x+2}[/tex]
Taking LCM on both sides, we get
[tex]\dfrac{(x-3)(x+1)+3x-3}{(x+1)(x+2)}=\dfrac{x(x+2)-(x+1)(x-2)}{(x+1)(x+2)}[/tex]
[tex](x-3)(x+1)+3x-3=x(x+2)-(x+1)(x-2)[/tex]
[tex]x^2+x-3x-3+3x-3=x^2+2x-(x^2-2x+x-2)[/tex]
[tex]x^2+x-6=x^2+2x-x^2+2x-x+2[/tex]
On further simplification, we get
[tex]x^2+x-6=3x+2[/tex]
[tex]x^2+x-6-3x-2=0[/tex]
[tex]x^2-2x-8=0[/tex]
Splitting the middle term, we get
[tex]x^2-4x+2x-8=0[/tex]
[tex]x(x-4)+2(x-4)=0[/tex]
[tex](x+2)(x-4)=0[/tex]
[tex]x=-2,4[/tex]
But [tex]x\neq -2[/tex] because for [tex]x=-2[/tex] the given equation is not defined.
Therefore, the only solution of the given equation is [tex]x=4[/tex].

Answer:
5 1/2
Step-by-step explanation:
You can use the distributive property to eliminate parentheses, then add the terms that result.
5(3/5 +1/2) = 5(3/5) +5(1/2) = 3 + 5/2 = 3 + 2 1/2 = 5 1/2
__
Or, you can add the numbers, then multiply by 5. This is the way the evaluation should be done according to the Order of Operations.
5(3/5 +1/2) = 5(6/10 + 5/10) = 5(11/10) = 11/2 = 5 1/2
Answer:
5 1/2.
Step-by-step explanation:
5*(3/5+1/2)
= 5 * (6/10 + 5/10)
= 5 * 11/10
= 55/10
= 5 1/2.
What area is this shape ?
9514 1404 393
Answer:
40 square units
Step-by-step explanation:
The area can be considered as that of two trapezoids, a rectangle, and a triangle. The total area is the sum of the areas of these.
Draw two horizontal lines, one beginning at the left-most point, and another 2 units below that. Draw a vertical line segment extending the vertical line at the top down to the first horizontal line. Now the figure is divided as described above.
The upper left trapezoid has bases of 3 and 5, and a height of 4. Its area is ...
A = 1/2(b1 +b2)h
A = (1/2)(3 +5)(4) = 16
The trapezoid between the two horizontal lines has bases of 8 and 7, and a height of 2. Its area is ...
A = (1/2)(8 +7)(2) = 15
The rectangle at upper right has a base of 2 and a height of 3. Its area is ...
A = bh
A = 2(3) = 6
The triangle at the bottom has a base of 3 and a height of 2. Its area is ...
A = 1/2bh
A = 1/2(3)(2) = 3
Then the total area of all of these pieces is ...
Area = 16 +15 +6 +3 = 40 . . . . square units
Answer:
the answer is 40 square units
