You never scale down to write a complex rate as a unit rate. True or false?
Answer:
True
Step-by-step explanation:
We should use simple units while doing any type of calculation, using simple units make it easy for other people to kn ow the calculation, on the contrary if we use complex units then it will make the calculation more complicated thereby increasing the chances of mistake.
Pls help i dont understand :( will give Brainliest + 25 Points
Answer:
D
Step-by-step explanation:
Find the slope using the formula [ y2-y1/x2-x1 ]
2-2/-5-3
0/-8
0
Find the y-intercept using slope-intercept form [ y = mx + b ] and (3, 2)
y = 0x + b
2 = 0(3) + b
2 = b
Put everything we know into the final form.
y = 0x + 2
y = 2
Best of Luck!
change in y/change in x
y2-y1/x2-x1
2-2/-5-3
0/-8 = 0
The slope is 0 - the answer is d
because when 0x = 0, then you are left with y and only y
when the equation is x=, then the equation is undefined
but, when an equation is y=, that the slope is 0
Simplify the expression given below x^2 + x-2
Find the product, using suitable properties:

Ava read an article claiming that 10% of people in her county were senior citizens, and she wondered if this held true for residents in her city. She took a random sample of 225 people from her city to test H0 : p = 0.10, where p is the proportion of people in her city that are senior citizens. Ava found that approximately 14% of those sampled were senior citizens. She conducted an appropriate significance test, and the resulting test statistic was z ≈ 1.89z. Assume that the conditions for inference were met.
Complete Question
Ava read an article claiming that 10% of people in her county were senior citizens, and she wondered if this held true for residents in her city. She took a random sample of 225 people from her city to test H0 : p = 0.10, where p is the proportion of people in her city that are senior citizens. Ava found that approximately 14% of those sampled were senior citizens. She conducted an appropriate significance test, and the resulting test statistic was z ≈ 1.89 z. Assume that the conditions for inference were met.calculate the p-value for Ellie's significance test
Answer:
The p-value is [tex]p-value = 0.0588[/tex]
Step-by-step explanation:
From the question we are told that
The percentage of senior citizens is p = 0.10
The sample size is [tex]n = 225[/tex]
The sample proportion is [tex]\^{p} = 0.14[/tex]
The test statistics is [tex] z \approx = 1.89[/tex]
The null hypothesis is [tex]H_o : p = 0.10[/tex]
The alternative hypothesis is [tex]H_a : p \ne 0.10[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(Z > 1.89 )[/tex]
From the z-table
[tex]P(Z > 1.89 ) = 0.029379[/tex]
=> [tex]p-value = 2 * 0.029379[/tex]
=> [tex]p-value = 0.0588[/tex]

No because 0.06>0.05

-5x + 9 = -3x + 1 solve the equation
Answer:
x=4
Step-by-step explanation:
Step 1: Add 3x to both sides.
−5x+9+3x=−3x+1+3x
−2x+9=1
Step 2: Subtract 9 from both sides.
−2x+9−9=1−9
−2x=−8
Step 3: Divide both sides by -2.
−2x/−2=−8/−2

Step-by-step explanation:
Solve.
x^2 + 4 = 0.
Answer:
No real solutions
Step-by-step explanation:
You use the quadratic formula.
x = −b ± √(b^2 − 4ac)/2a where y = ax^2 + bx + c
b is 0, a is 1, and c is 4.
-0 ± √(0^2 − 4 x 1 x 4)/ 2(1)
±√(-16)/2
Split √(-16) into √(16) and √(-1).
Now, i = √-1
So you get ±√(-16) = ±4i.
The original equation was ±√(-16)/2.
±4i / 2 = ±2i
The answer is x = ±2i
(Note: ± means positive or negative)
What is the relationship between the constant propprtionality of 50 and 0.02
Answer:
Inverse Proportionality
Step-by-step explanation:
Given
Constants 50 and 0.02
Required
Determine the relationship
Let y = 0.02
Convert 0.02 to fraction
y = 2/100
Simplify to lowest form
y = 1/50
Recall that y = 0.02
0.02 = 1/50
From the above expression, we can conclude that the relationship between both is inverse.
In other words, 50 and 0.02 are inversely proportional

what is the area of a rectangles with the side lengths 5 inches and 4/3 inches?
Answer: 20/3 square inches
Step-by-step explanation:
Area = length*width
length = 5 in.
width = 4/3 in.
A = 5 * (4/3) = 20/3 in^2

True or False
If a quadrilateral is a square then it is also a rectangle. *
True or False
If a quadrilateral is a trapezoid then it is also a parallelogram.
True or False
Answer: true
Step-by-step explanation:
Step-by-step explanation:
"A parallelogram has one pair of parallel sides."
False. A parallelogram has two pairs of parallel sides.
"If a quadrilateral is a rectangle then it is also a square."
False. A rectangle isn't necessarily a square. Rectangles are only squares when all four sides are equal.
"A parallelogram always has four congruent sides."
False. Parallelograms have two pairs of congruent sides. All four sides aren't necessarily congruent.
"If a quadrilateral is a square then it is also a rectangle."
True. All squares are rectangles.
"If a quadrilateral is a trapezoid then it is also a parallelogram."
False. Trapezoids have only 1 pair of parallel sides, and parallelograms have 2 pairs of parallel sides.
