(a) Example of data with SS(between) = 0 and SS(within) > 0: Identical height measurements in different sections of a uniform greenhouse.
(b) Example of data with SS(between) > 0 and SS(within) = 0: Significant difference in plant growth due to different fertilizers.
(c) ANOVA conclusion: Reject the null hypothesis, indicating a significant difference in mean HBE levels among the three groups.
(d) Pooled standard deviation: Spooled = 14.188.
(a) Example of data with SS(between) = 0 and SS(within) > 0:
Suppose we are measuring the height of plants in three different sections of a greenhouse, and the greenhouse has a uniform environment. If we take three samples of size 5 from each section and the height measurements are identical in all three sections, then we will have SS(between) = 0 and SS(within) > 0.
(b) Example of data with SS(between) > 0 and SS(within) = 0:
Suppose we are testing the effectiveness of three different fertilizers on plant growth. We take three samples of size 5 and apply each fertilizer to a different group of plants. If one fertilizer results in significantly greater growth compared to the other two, then we will have SS(between) > 0 and SS(within) = 0.
(c) ANOVA table:
Source SS df MS F
Between groups 240.69 2 120.345 F = 34.64
Within groups 6,887.6 33 208.713
Total 7,128.29 35
Null hypothesis:
The null hypothesis is that the mean HBE levels are equal across all three groups.
Symbolically, H0: μ1 = μ2 = μ3.
Test:
Using an F-test with α = 0.05 and degrees of freedom df(between) = 2 and df(within) = 33, we find that the calculated F-value of 34.64 is greater than the critical value of 3.18. Therefore, we reject the null hypothesis and conclude that there is a significant difference in the mean HBE levels among the three groups.
(d) Pooled standard deviation:
Spooled = sqrt((MS(within) * (n1-1) + MS(within) * (n2-1) + MS(within) * (n3-1)) / (n1 + n2 + n3 - 3))
Substituting the values from the ANOVA table, we get:
Spooled = sqrt((208.713 * (15-1) + 208.713 * (11-1) + 208.713 * (10-1)) / (15 + 11 + 10 - 3)) = 14.188
Therefore, the pooled standard deviation is 14.188.

Select the pair of terms that are NOT like terms. a) 3x2 , 3x3 b) -7xy, -9yx c) 8b, -0.5b d) -p2q2 , (pq)2
Answer:
b), c), d)
Step-by-step explanation:
Like terms are terms that have same variables with same powers.
a)
[tex]3x^2,3x^3[/tex] have same variable [tex]x[/tex] with different powers.
So, [tex]3x^2,3x^3[/tex] are not like terms.
b) [tex]-7xy,-9yx[/tex]
Power of [tex]x[/tex] in each of the terms = 1
Power of [tex]y[/tex] in each of the terms = 1
[tex]-7xy,-9yx[/tex] are terms that have same variables [tex]\{x,y\}[/tex] with same powers.
So, [tex]-7xy,-9yx[/tex] are like terms.
c) [tex]8b,-0.5b[/tex]
Power of [tex]b[/tex] in each of the terms = 1
[tex]8b,-0.5b[/tex] are terms that have same variable [tex]b[/tex] with same power.
So, [tex]8b,-0.5b[/tex] are like terms.
d) [tex]-p^2q^2,(pq)^2=p^2q^2[/tex]
Power of [tex]p[/tex] in each of the terms = 1
Power of [tex]q[/tex] in each of the terms = 1
[tex]-p^2q^2,(pq)^2[/tex] are terms that have same variables [tex]\{p,q\}[/tex]with same powers.
So, [tex]-p^2q^2,(pq)^2[/tex] are like terms
Using Proportions to Make a Prediction
Of 25 grocery store shoppers, 14 said that their family’s favorite breakfast is cereal bars. Predict how many of 500 families at grocery store would buy cereal bars.
Of 200 radio-controlled cars that were manufactured by one company, 3 were defective. The company manufactures 1000 cars each day. About how many
defective cars would you predict are produced each day?
HELP......HELP......HELP
Ratio of people who said they like cereal bars to people who said they don't = 14:11
Number of people at a grocery shop = 500
Which means :
[tex] =\tt \frac{14}{25} \times 500 [/tex]
[tex] =\tt \frac{14 \times 500}{25} [/tex]
[tex] = \tt \frac{7000}{25} [/tex]
[tex] \color{plum}= \tt280 \: people[/tex]
Thus, 280 people would buy cereal bars.
▪︎Therefore, out of 500 people, 280 people would buy cereal bars.
○=> Solution (2) :Ratio of cars which worked well to cars which were defective = 297:3
Number of care produced each day = 1000
Number of defective cars produced each day :
[tex] = \tt \frac{3}{200} \times 1000[/tex]
[tex] =\tt \frac{3 \times 1000}{200} [/tex]
[tex] = \tt\frac{3000}{200} [/tex]
[tex]\color{plum} = \tt15 \: defective \: cars[/tex]
Thus, 15 defective cars are produced.
▪︎Therefore, out of 1000 cars produced each day, 15 cars are defective.

There is a sale on Blu-rays in a local shop – 20% off selected items. Your favorite Blu-ray before the sale cost $18. How much will you save? How much will you pay?
Answer:
save $3.6, pay $14.4
Step-by-step explanation:
A cd costs $18
If there is a 20% discount, you only have to pay 80% of the original price.
This means you only have to pay (0.80 x $18=) $14.4 dollars, which means you saved ($18 - $14.4=) $3.6.
Or you could just do $18 x 0.20 = $3.6

Jesse made a list of chores he needed to complete before his father came home from work and he showed the time it would take him to complete each chore.
If Jesse's father is expected home at 6:10 p.m., what is the latest time Jesse could begin his chores?
A. 3;45 p.m.
B. 3:55 p.m.
C. 4:05 p.m.
D. 4:15 p.m.
Answer:
3:55 pm
Step-by-step explanation:
Lets add all the time duration of each chore to know the overall time taken to complete all the chores .
Total time taken to finish the chores :-
5 + 25 + 30 + 60 + 15 = 135 mins or 2hr 15 min
If Jesse's father is expected to come at 6:10 pm , the exact time he should begin his chores is :-
6:10 - 2:15 = 3:55 pm

Answer:
as the cycle continues, you will always get 50 as the answer, since you are dividing both the numerator and the denominator with 10 in each expression. In other words, the 10:00 you divide the numerator which cancels out with the 10 you divide the denominator with. So the answer will always be 50 in each next expression.
Step-by-step explanation:
(I) 45÷90= 4500/90 = 50
(ii) 450÷9= 450/9 =50
(iii) 45÷0.9 = 45/0.9=50
(iv) 4.5 ÷ 0.09 = 45/0.09
starting with (I) 4500÷90 = 4500/90 =50
you divide the numerator and the denominator by 10 to get ; (ii) 450÷9 = 450/9 = 50
as the cycle continues you will always get 50 as the answer since you are dividing both the numerator and the denominator with 10 in each expression. In other words, the 10:00 you divide the numerator with cancels out with the 10 you divide the denominator with. So the answer will always be 50.

Answer:
you wrote that wrong cause ur answer is 0.01225490196
Step-by-step explanation:
Answer:
The answer is 321.6
Step-by-step explanation:
We have to go step by step when we are solving this.
Lets think of it like this
Does 25 go into 8? No! So lets put a 0 on the top (I see you already did that so good start)
Does 25 go into 80? Yes! How many times though? 3 times; So lets put a 3 on the top (Our top should look like 03) Since 25 goes into 80 3 times we need to multiply 25 and 3.
25x3= 75 -> Subtract that 75 from 80
Now we have a remainder of 5. We are going to bring down the 4 so it can be a complete number, and now it would be 54.
Does 25 go into 54? Yes! How many times? 2 times; So lets put a 2 on the top (Our top should look like 032) Since 25 goes into 54 2 times we have to multiply 25 and 2.
25x2=50 -> subtract that 50 from 54 -> 54-50=4
Now we have a remainder of 4. Bring down the last number, 0 and now we should be with 40.
Does 25 go into 40? Yes! How many times? 1 time; therefore we will just be subtracting 25 from 40. (our top should look like 0321)
40-25= 15 -> we have a remainder of 15. 25 can't go into 15 because 15 is too small. Therefore we are going to have to make a decimal. So on the top add a decimal after 1 and bring down an invisible 0. (Our top looks like this 0321.)
Does 25 go into 150? Yes! How many times? 6 times; so lets multiply 25 and 6 and then subtract that from our 150 that is down there.
25*6= 150
150-150= 0
THAT MEANSSSSS..... our answer is 321.6! P.S yes drop that 0!

How is this equation wrong?? I’m giving brainlest
Answer:
It isn't?
Step-by-step explanation:
Step 1:
x + 8y = 21
x + 8y - 8y = 21 - 8y
x = -8y + 21
Step 2:
(-8y + 21) + 8y = 21
-8y + 21 + 8y = 21
21 = 21

Uri has 22 same-sized circles that are divided into different numbers of equal-sized parts. He shades 1/5 of the first circle. The second circle has three times as many parts as the first circle. Uri shades an equivalent fraction of the second circle. What fraction of the second circle does Uri shade?
Answer:
The fraction of the second circle does Uri shade = [tex]\frac{1}{15}[/tex]
Step-by-step explanation:
As given,
Total number of same sized circle = 22
In first circle :
He shades [tex]\frac{1}{5}[/tex] of the first circle.
⇒ He divide the first circle in 5 parts and shaded 1 part.
Now,
The second circle has three times as many parts as the first circle.
⇒Total parts of second circle = 3 × 5 = 15
Now,
Given that Uri shades an equivalent fraction of the second circle.
⇒Uri shade second circle = [tex]\frac{1}{15}[/tex]
∴ we get
The fraction of the second circle does Uri shade = [tex]\frac{1}{15}[/tex]
