Answer:
There is a significant relation between weight and price
Step-by-step explanation:
Brand Weight(x) Price ($) (y)
A 17.8 2100
B 16.1 6,250
C 14.9 8,370
D 15.9 6,200
E 17.2 4,000
F 13.1 8,500
G 16.2 6,000
H 17.1 2,580
I 17.6 3,500
J 14.1 8,000
Null Hypothesis : [tex]H_0: \mu =0[/tex]
Alternate Hypothesis : [tex]H_a: \mu \neq 0[/tex]
Given : SST=51956800 SSE= 7312286.84 n = 10
SSR = SST-SSE
SSR=51956800-7312286.84
SSR=44644513.16
Level of significance =[tex]\alpha = 0.05[/tex]
[tex]F=\frac{\frac{SSR}{m}}{\frac{SSE}{n-k}}[/tex]
Where m = no. of restrictions
k = No. of independent variables
[tex]F=\frac{\frac{44644513.16}{1}}{\frac{ 7312286.84}{10-2}}[/tex]
F=48.843
Degree of freedom 1 = 1
Degree of freedom 2 = 10-2=8
Using calculator
p-value is .000114.
p value < α
So, we reject the null hypothesis .
Hence There is a significant relation between weight and price

Can someone please help me!!! Also does anyone know if there is a website or calculator that may give me the answers? Please help me! Thank you!
Answer:
[tex] x = 17 [/tex]
Step-by-step explanation:
[tex] 2x + 7 = 3x - 10 [/tex] (alternate exterior angles are congruent when a transversal cuts across two straight lines)
[tex] 2x - 3x = -7 - 10 [/tex] (collecting like terms)
[tex] - x = -17 [/tex]
[tex] \frac{-x}{-1} = \frac{-17}{-1} [/tex] (dividing both sides by -1)
[tex] x = 17 [/tex]

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]

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

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)
