Answer:
squares of the reciprocals of natural numbers
Step-by-step explanation:
The numbers are squares of the reciprocals of successive natural numbers.
1 : (1/1)^2 = 1
2 : (1/2)^2 = 1/4
3 : (1/3)^2 = 1/9
4 : (1/4)^2 = 1/16
5 : (1/5)^2 = 1/25
Answer:
squares of the reciprocals of natural numbers
Step-by-step explanation:
Find the slope of a parallel line -10+x-2y=0
Answer: 1/2
Step-by-step explanation:
First convert the equation into slope-intercept form.
-10 + x -2y = 0
+10 +10
x - 2y = 10
-x -x
-2y = 10 - x Divide both sides by -2
y = 1/2x - 5
In this case the slope is 1/2 and the slopes parallel lines are the same but they must have different y intercepts. Meaning that the slope of the other line will be 1/2.

Step-by-step explanation:
The number of square feet per house is normally distributed with a population standard deviation of 154 square feet and an unknown population mean. If a random sample of 16 houses is taken and results in a sample mean of 1550 square feet, find a 80% confidence interval for the population mean. Round your answer to TWO decimal places.
Answer: (1500.66,1599.34)
Step-by-step explanation:
Confidence interval for population mean:
[tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex]
,where [tex]\overline{x}[/tex] = Sample mean , n= Sample size, z* = critical two tailed z-value , [tex]\sigma[/tex] = population standard deviation.
As per given , we have
n= 16
[tex]\sigma = 154[/tex] square feet
[tex]\overline{x}= 1550[/tex] square feet
[tex]\alpha= 1-0.80 = 0.20[/tex]
Critical z-value = [tex]z_{\alpha/2}=z_{0.2/2}=z_{0.1}=1.2815[/tex]
Confidence interval for population mean:
[tex]1550\pm (1.2815)\dfrac{154}{\sqrt{16}}\\\\ = 1550\pm (1.2815)\dfrac{154}{4}\\\\= 1550\pm 49.33775\\\\ =(1550-49.33775,\ 1550+49.33775)\\\\\approx (1500.66,\ 1599.34)[/tex]

1. Solve using any method:
2x – 3y = -2
4x + y = 24
Answer:
[tex]x=5,y=4[/tex]
Step-by-step explanation:
[tex]2x-3y=-2[/tex]
Add 3y to both sides:
[tex]2x-3y+3y=-2+3y[/tex]
[tex]2x=-2+3y[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2}=-\frac{2+3y}{2}[/tex]
[tex]x=\frac{-2+3y}{2}[/tex]
Substitute this into the second equation:
[tex]4* \frac{-2+3y}{2}+y=24[/tex]
[tex]2\left(3y-2\right)+y=24[/tex]
[tex]7y-4=24[/tex]
Add 4 to both sides:
[tex]7y-4+4=24+4[/tex]
[tex]7y=28[/tex]
Divide both sides by 7:
[tex]\frac{7y}{7}=\frac{28}{7}[/tex]
[tex]y=4[/tex]
We know that [tex]x=\frac{-2+3y}{2}[/tex]
Thus, [tex]x=\frac{-2+3* \:4}{2}[/tex]
[tex]x=\frac{10}{2}[/tex]
[tex]x=5[/tex]

When a number x is divided by 24 the remainder is 23 and when it is divided by 36 the remainder is 35. Find the least number that x can be.
Answer:
7 is the answer. If a number can be divided by 36 then it can also be divided by 12 which is 3*12 therefor the remainder will be 19-12 which is 7. When 19 is divided by 36, the remainder is 19 and so 19 must be a number. When 19 is divided by 12 the remainder is 7.

Answer:
f(x)=2x^2-3x+1
the graph of the function is attached with the answer
As we can see that equation is quadratic and its graph is a parabola facing upward.
As we can see it passes the Vertical line test
As it passes the Vertical line test , So it is a function
And two values of x has one value of y

Step-by-step explanation:
Because if ZUY is 90 degrees and half of 90 degrees is 45 degrees but TUZ is a little bit less than the middle part of ZUY it has to be less than 45 degrees by a little bit and the only option would be 30 degrees. Hope this helped (:
What is (5•3) - 18 and can u explain y
Answer:
-3
Step-by-step explanation:
You would find what the answer to (5•3) is then subtract that answer with 18. So it would be 15-18=-3
Answer:
The answer is -3
Step-by-step explanation:
The answer is -3 because of the order of operations PEMDAS (parenthesis, exponent, multiplication/division, addition/subtraction)
Therefore, you would multiply the two numbers inside the parenthesis first, which would give you 15-18, and from there you can subtract 18 from 15 which would give you -3.

What is the volume of the rectangular prism?
A rectangular prism is a three-dimensional shape. It also known as a cuboid. It has six faces, 12 sides and 6 vertices
Volume = length x width x height
Volume = 1/3 (number of squares that make up the length x number of squares that make up the width x number of squares that make up the height)
1/3 (5 x 2 x 3) = 10 feet^3
