hi hun!
From what I understand, ill explain to the best of my knowledge so u understand!
First. off they asked for "proportionality" basically asking for the rate it's growing at or weeks its taking.
I see that:
Flower 1: 6 inches
Flower 2: 10 inches
Flower 3: 14 inches
The proportionality which these flowers are growing at is 4 inches every two weeks.
And I also see:
Week 3
Week 5
Week 7
When u look closer u can see that the weeks are divisible by the inches for each of the flowers and each answer u get is 2!
And also just by looking at the weeks which are 2 weeks separate if u count them.
Week 3 would be:
6/3=2
Week 5 would be:
10/5=2
Week 7 would be:
14/7=2
so the proportionality is 2! c:

Answer:
The degrees of freedom are:
The confidence level is 0.95 or 95%, the significance would be
and
, the critical value for this case would be
And replacing we got:
Step-by-step explanation:
Information given
In order to calculate the mean and the sample deviation we can use the following formulas:
(2)
(3)
represent the sample mean
population mean
s=9.956 represent the sample standard deviation
n=10 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are:
The confidence level is 0.95 or 95%, the significance would be
and
, the critical value for this case would be
And replacing we got:
Cube rooting a number that is the result of cubing a number means you will end up with the original number again.
for example, if you do 3 cubed you get 27, and the cube root of 27 is 3. This means Julio started with the number 20
Answer:
Cream = 3 cups
Chocolate = 6 cups
Step-by-step explanation:
Cream = 1 cup
Chocolate = 2 cups
Total = 3 cups
Cream : chocolate = 1 : 2
He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?
Cream = ratio of cream/total ratio of total cups
= 1/3 of 9
= 1/3 × 9
= 3 cups
Cream = 3 cups
Chocolate = ratio of chocolate/total ratio of total cups
= 2/3 of 9
= 2/3 × 9
= 6 cups
Chocolate = 6 cups
The volume is 33.5mm^3 (or cubed)
Formula : v = 4/3πr^3 or v = 4 x 3.14 x (r x r x r) <span>÷ 3
</span>
~ 2 x 2 x 2 = 8 (we use 2 because the radius is half of the diameter)
v = 4 x 3.14 x 8 <span>÷ 3 a. Multiply everything together
v = 100.48 </span><span>÷ 3 b. Divide by 3</span><span>
v = 33.493 c. Round (if needed)
</span>v = 33.5
