I added three non-unit fractions together to make a whole. What three fractions could that be?
Answers
Answer:
For example \(\frac{2}{6}\)
Step-by-step explanation:
A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.
For example: \(\frac{2}{6}\), because 3· \(\frac{2}{6}\) = \(\frac{6}{6}\) = 1
Infinitely many solutions can be found: for example \(\frac{3}{9} , \frac{4}{12} , etc\)

Use the zero product property to find the solutions to the equation (x + 2) (x + 3) = 12.
a. x = –6 or x = 1
b. x = –3 or x = –2
c. x = –1 or x = 6
d. x = 2 or x = 3
Answers
Step-by-step explanation:
(x + 2)(x + 3) = 12
x² + 5x + 6 = 12
x² + 5x - 6 = 0
(x + 6)(x - 1) = 0
By zero product rule, we have (x + 6) = 0 or (x - 1) = 0.
=> x = -6 or x = 1. (A)

a distribution of values is normal with a mean of 164.8 and a standard deviation of 92.6. find p42, which is the score separating the bottom 42% from the top 58%.
Answers
The raw score which is the score separating the bottom 42% from the top 58% is 183.32.
The given variable is a normal distribution variable.
Mean of the variable is given by = µ = 164.8
Standard deviation of the variable is given by = s = 92.6
Let the p42 or the score separating the bottom 42% from the top 58% be x.
z = (x - 164.8)/92.6
So, P(Z < z) = 0.42
We know that normal distribution table that P(Z < -0.21) = 0.42
So, z = - 0.21
(x - 164.8)/92.6 = 0.21
x - 164.8 = 0.21*92.6
x - 164.8 = 18.52
x = 18.52 + 164.8
x = 183.32
Hence the required raw score will be 183.32.

Step-by-step explanation:
You want the simplified form of the expression -2i(5- i) + (17- 8i).
Complex numbersFor many purposes, the value i in a complex number can be treated in the same way a variable would be treated. When simplifying an expression involving i, any instances of i² can be replaced with the real value -1.
-2i(5- i) + (17- 8i) = -10i +2i² +17 -8i

b) alternative hypothesis.
What is meant by an alternative hypothesis?In statistical hypothesis testing, the alternative hypothesis is one of the suggested propositions in the hypothesis test. In general, the purpose of a hypothesis test is to demonstrate that, under the given conditions, there is sufficient evidence to support the believability of an alternate hypothesis rather than the test's exclusive statement (null hypothesis). Because it is based on a review of the literature and previous studies, it is usually congruent with the research hypothesis. However, the research hypothesis is sometimes congruent with the null hypothesis.
In statistics, alternative hypotheses are frequently denoted as Hₐ or H₁. In a statistical hypothesis test, hypotheses are developed to be compared.
In the field of inferential statistics, two competing hypotheses can be compared using explanatory and predictive power.

solve (x+21)+(2x+9)=90
Answers
Answer:
The answer is x=20
Step-by-step explanation:
Answer:
x = 20
Step-by-step explanation:
(x+21)+(2x+9)=90
x + 21 + 2x + 9 = 90
combine numbers on left side:
x + 30 + 2x = 90
combine x terms on left side:
3x + 30 = 90
subtract 30 from both sides:
3x + 30 -30 = 90 - 30
3x = 60
divide both sides by 3:
3x/3 = 60/3
x = 20

What is rectangle?
A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. You might also describe it as follows: a quadrilateral that is equiangular, which indicates that all of its angles are equal. The parallelogram might also have a straight angle. Squares are rectangles with four equally sized sides. A quadrilateral of the shape of a rectangle has four 90-degree vertices and equal parallel sides. As a result, it is sometimes referred to as an equirectangular rectangle. Because its opposite sides are equal and parallel, a rectangle is also known as a parallelogram.
Given that the length of the rectangular space is three times its breadth
The chamber has a 56-meter perimeter.
Assume that the room's width is x.
As a result, the room is three times as long.
The room's perimeter is now equal to 2(3x + x).
\(Here, 2(3x + x) = 56\\ 2 * 4x = 56\\ 8x = 56\\ x = 7.\)
Consequently, the room has a 7 meter width.
The room's length is
\(= 7 * 3 meters\\= 21 meters\)

In 2010, the population of a city was 167,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 3%. How much did the population decrease from 2015 to 2020, to the nearest 100 people?
Answers
The population decreased by 5,400 people from 2015 to 2020.
By how much did the population decrease?Also known as population decline, means the reduction in a human population size
Population in 2015 = Population in 2010 + Growth from 2010 to 2015
Population in 2015 = 167,000 + (8% of 167,000)
Population in 2015 = 167,000 + 13,360
Population in 2015 = 180,360
Population in 2020 = Population in 2015 - Decrease from 2015 to 2020
Population in 2020 = 180,360 - (3% of 180,360)
Population in 2020 = 180,360 - 5,411.8
Population in 2020 = 174,948.2
The population decrease from 2015 to 2020 is:
= Population in 2015 - Population in 2020
= 180,360 - 174,948.2
= 5,411.8
= 5,400 to nearest 100 people.
