Yes, 68.25 is near the top of the confidence interval.
Yes, the value of 68.25 is a number in the confidence interval.
Yes, 68.25 is much higher than the sample mean of all three-year-old thoroughbred racehorses, which was 65.2 inches.
No, the value of 68.25 is a number in the confidence interval.
No, the horses that run in the Kentucky Derby are a subset of all three-year-old thoroughbred racehorses
Answer:
No , the value of 68.25 is a number in the confidence interval.
Step-by-step explanation:
The confidence interval gives a range if values which is used in establishing the significance of an hypothesis. If the true mean falls within the confidence interval drawn, then our finding is insignificant and the null hypothesis will stand. However, if the true mean does not fall within the interval, then our result is considered significant and the null is thus rejected.
Since true mean exists within the confidence interval, then we conclude that the sample does not provide convincing evidence that three-year-old thoroughbred racehorses are, on average, shorter than those that run in the Kentucky Derby
Let theta be and angle in quadrant IV that has reference pi/3. What is sin(theta)?
Given:
[tex]\theta[/tex] is an angle in quadrant IV that has reference [tex]\dfrac{\pi}{3}[/tex].
To find:
The value of [tex]\sin \theta[/tex].
Solution:
We know that only cos and sec are positive in quadrant IV and all other trigonometric ratios are negative in quadrant IV.
Since [tex]\theta[/tex] is an angle in quadrant IV that has reference [tex]\dfrac{\pi}{3}[/tex], therefore the value of [tex]\sin \theta[/tex] must be negative.
[tex]\sin \theta=-\sin \dfrac{\pi}{3}[/tex]
[tex]\sin \theta=-\dfrac{\sqrt{3}}{2}[/tex]
Therefore, the required value is [tex]\sin \theta=-\dfrac{\sqrt{3}}{2}[/tex].

this would be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
15² + 19²
225 + 361
586

It takes 15 caterpillars 24 hours to eat all the leaves on the bush in Violetta's front
yard. How
many
hours would it take 18 caterpillars to eat the same bush, assuming al
caterpillars eat at the same pace?
Answer:
20 hours
Step-by-step explanation:
[tex]\frac{15}{24}[/tex]=[tex]\frac{18}{x}[/tex]
15÷18=1.2
x=24÷1.2= 20 hours
20 hours is the answer
The time taken by 18 caterpillars to eat the entire Bush in Violetta's front yard is 20 hours.
What is the time taken?Time taken is the inverse of the rate of work.
As it is given that the time taken by 15 caterpillars to eat all the leaves on the bush in Violetta's front yard is 24 hours, therefore, the rate at which the 15 caterpillars eat the leaves can be written as,
[tex]\rm Rate = \dfrac{\text{Number of Bush That caterpillars eat}}{\text{Time taken by the caterpillars}}[/tex]
[tex]\rm Rate = \dfrac{1}{24}[/tex]
Now, as it is the rate of 15 caterpillars, therefore, the rate of a single caterpillar can be written as,
[tex]\rm Rate = \dfrac{\frac{1}{24}}{15} = \dfrac{1}{24 \times 15}[/tex]
Now, the time taken by 18 caterpillars can be written as,
[tex]\rm Time\ taken = \dfrac{Work}{Rate \times 18}\\\\\rm Time\ taken = \dfrac{1}{\dfrac{1}{24 \times 15}\times 18}\\\\Time \taken = \dfrac{24 \times 15}{1 \times 18} = 20 \ hours[/tex]
hence, the time taken by 18 caterpillars to eat the entire Bush in Violetta's front yard is 20 hours.

Paola made a rectangular painting that has an area of 24 square feet. He now wants to make a similar
painting that has dimensions that are 2/3 the size of the original. What will the area of the new painting
be?
A.) 36 square feet
B.) 16 square feet
C.)12 square feet
D.) 10 2/3 square feet
Answer:
D.) 10 2/3 square feet

Bella has $540 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
She buys a new bicycle for $353.59.
She buys 3 bicycle reflectors for $4.98 each and a pair of bike gloves for $38.63.
She plans to spend some or all of the money she has left to buy new biking outfits for $49.20 each.
Write and solve an inequality which can be used to determine xx, the number of outfits Bella can purchase while staying within her budget.
Step-by-step explanation:
$540 - $353.59 = $186.41
$186.41 - $4.98 = $181.43
$181.43 - $38.67 = $142.8
She has $142.8 left and if she want to buy the outfits for $49.20 she is going to have $93.6 left

Answer:
A) 65
B) 5
C) 242
D) 531
E) 36
Step-by-step explanation:
A) Let the unknown term be x.
Difference between 5 & 9 = 4
Difference between 9 & 17 = 8 = 4×2
Difference between 17 & 33 = 16 = 8×2
It is observed that the difference between two terms is getting doubled. So,
Difference between 33 & x = 16×2 = 32
∴ x = 33 + 32 = 65
B) Let the unknown term be x.
Difference between 20 & 12 = 8
Difference between 12 & 8 = 8/2 = 4
Difference between 8 & 6 = 4/2 = 2
It is observed that the difference between two terms is getting halved.
Difference between 6 & x = 2/2 = 1
∴ x = 6 - 1 = 5
C) Let the unknown term be x.
Difference between 2 & 8 = 6
Difference between 8 & 26 = 18 = 6×3
Difference between 26 & 80 = 54 = 18×3
It is observed that the difference between two terms is getting tripled.
Difference between 80 & x = 54×3 = 162
∴ x = 80 + 162 = 242
D) Let the unknown term be x.
Difference between 36 & 69 = 33
Difference between 69 & 135 = 66 = 33×2
Difference between 135 & 267 = 132 = 66×2
It is observed that the difference between two terms is getting doubled.
Difference between 267 & x = 132×2 = 264
∴ x = 267 + 264 = 531
E) Let the unknown term be x.
4 = 2²
9 = 3²
16 = 4²
25 = 5²
It is observed that all the terms in the sequence are squares of consecutive natural numbers.
So, x = 6² = 36
