Specifications for a part for a DVD player state that the part should weigh between 24 and 25 ounces. The process that produces the parts has a mean of 24.5 ounces and a standard deviation of .2 ounce. The distribution of output is normal. a. What percentage of parts will not meet the weight specs
Answer:
The answer is "2.5".
Step-by-step explanation:
[tex]\to \frac{(25-24.5)}{0.2}= \frac{(0.5)}{0.2}=2.5[/tex]

express the sum of 2x and y is multiplied by 5 in an algebraic expressions
Answer:
(2x + y)*5
Step-by-step explanation:
Translating the word problem into an algebraic expression, we have;
(2x + y) * 5
Simplifying an expression simply means to collect like terms that are having the same variables or constants and combining them, so as to reduce the expression to the lowest possible value.
Simplifying further by opening the bracket, we have;
(2x + y)*5 = 10x + 5y

Determine whether the given figure tessellates the plane.
a. yes
b. no
Please select the best answer from the choices provided
Answer:
A. Yes
Step-by-step explanation:
I calculated it logically
Yes the given figure with rectangle tessellates the plane.
A rectangle cannot tessellate a plane by itself because it is not a regular polygon with equal angles and sides.
A rectangle can only tessellate the plane if it is combined with other shapes, such as squares or triangles, to form a regular tessellation.
Yes, the given figure tessellates the plane.
Hence, Yes the given figure tessellates the plane.

Instead of power posing in horses, you are interested in whether music can induce a mere exposure effect at short timescales. You read a paper that claims that it can, reporting a significant mere exposure effect. Alpha level was 0.05, the ratio of true to false effects in this field is 0.7 and the power of this study was 0.8. The probability that this effect is real is
Answer:
"0.9739" is the correct answer.
Step-by-step explanation:
The given values are:
The ratio of true to false effects,
= 0.07
The power of study,
= 0.8
Alpha level,
= 0.05
Now,
The percentage of effects proved as significant will be:
= [tex]0.8\times \ 70 \ percentage[/tex]
= [tex]0.56[/tex]
0r,
= [tex]56[/tex]%
The percentage of false effects will be:
= [tex]0.05\times 30 \ percent[/tex]
= [tex]0.015[/tex]
or,
= [tex]1.5[/tex]%
The total effects will be:
= [tex]56+1.5[/tex]
= [tex]57.5[/tex]%
hence,
The probability that this effect is real will be:
= [tex]\frac{56}{57.5}[/tex]
= [tex]0.9739[/tex]
The length of rectangular playground exceeds twice its width by 15 feet, and the
perimeter of the playground is 540 feet. What is the area of the playground in square feet?
Answer:
Width=85. Length=185. Area=15,725
Step-by-step explanation:
540/2=270, which is the sum of length+width.
270-15=255, so what's left is width+width+width.
255/3=85.
85*2=170
170+15=185
85*185=15,725

To find:
The simplified form of the given expression.
Solution:
We have,
[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}[/tex]
It can be written as
[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=\dfrac{7^{x}\cdot 7^{2}-9\cdot 7^x}{-20\times 7^x}[/tex]
[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=\dfrac{7^{x}(49-9)}{-20\times 7^x}[/tex]
Cancel out the common factors.
[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=\dfrac{40}{-20}[/tex]
[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=-2[/tex]

Find the circumference of the circle. Use 22/7 for pi.
Answer:
44
Step-by-step explanation:
circumference = 2πr = 2*(22/7)*(14/2) = 44
Answer:
C = 44 cm
Step-by-step explanation:
The diameter is 14.
The formula for circumference is
C = pi * d where d is the diameter
C = 22/7 * 14
C = 22 * 2
C = 44 cm

What quadrant does the angle 250 degrees lie in?
Answer: 3rd quadrant
Step-by-step explanation:
This is a question relating to trigonometry.
First quadrant = Angles between 0∘ and 90∘.
Second quadrant = Angles between 90∘ and 180∘
Third quadrant = Angles between 180∘ and 270∘
Fourth quadrant = Angles between 270∘ and 360∘
Therefore, since 250° is between 180° and 270°, it's in the 3rd quadrant.

You earn many points
Answer: 2200
Step-by-step explanation:
First we will find the area of the triangle, the formula for that is bh/2
(base multiplied by height divided by 2) then we input the numbers into our formula, 30 is the height of the triangle and 40 is the length of the base. So we have to solve 40*30/2 which is 600, then we solve for the square on the bottom which is b*h ( base multiplied by height) so it is 40*40, so we would get 1600, then we add 600 and 1600 together and get 2200.
Determine the equation of the circle graphed below.
