4 Pythagorean Theorem, Hypotenuse : HELP PLEASE ITS DUE I WILL GIVE BRAINLIIEST
Answer:
[tex]5\sqrt{82}[/tex] units
[tex]\sqrt{84910}[/tex] units
Step-by-step explanation:
According to Pythagoras theorem, square of hypotenuse is equal to sum of squares of other two sides.
Consider the first figure:
Let [tex]x[/tex] denotes length of the third side.
[tex]23^2+39^2=x^2\\529+1521=x^2\\2050=x^2[/tex]
[tex]x=5\sqrt{82}[/tex] units
Consider the second figure:
Let [tex]y[/tex] denotes length of the third side.
[tex]87^2+96^2=y^2\\7569+9216=y^2\\84910=y^2\\[/tex]
[tex]y=\sqrt{84910}[/tex] units
how to find the scale factor of something
Answer:
To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. In this example, the scale factor from the blue figure to the red figure is 1.6 : 3.2, or 1 : 2.

3. Mara spent 3/5 of her vacation in British Columbia. While in that province,
she spent ½ of her time in Vancouver. What fraction of her vacation did
Michaela spend in Vancouver? If her vacation lasted 20 days, how many
days did she spend in Vancouver? Explain your answer.
Answer:
#1
30% of 70 ⇒ 0.3*70 = 21x% of 84 = 21x*84/100 = 21x = 2100/84x = 25%#2
75% of 36 = x% of 580.75*36 = 0.58x0.58x = 27x = 27/0.58x = 46.55%#3
1/2 of 3/5 ⇒ 1/2*3/5 = 3/10 3/10 of 20 days ⇒ 3/10*20 = 6 daysThe product of two consecutive even numbers is 360. Find the numbers.
List each pair of numbers in parentheses, separated by a comma. Example: (1,2),(3,4).
Answer:
Step-by-step explanation:
Two consecutive numbers be 2x , (2x + 2)
(2x)(2x + 2) = 360
2x*2x + 2x *2 = 360
4x² + 4x = 360 {divide the equation by 4}
x² + x = 90
x² + x - 90 = 0
x² + 10x - 9x - 9*10 = 0
x(x + 10) - 9(x + 10) = 0
(x + 10)(x -9) = 0
x + 10 = 0
x = -10
2x = 2*(-10) = -20
2x + 2 = -20 + 2 = 18

A golf pro wants to determine if Titleist Pro V1 golf balls (1) travel farther, on average, than Callaway Chrome Soft golf balls (2). A robot hits 9 of each ball, selected at random, and the distance traveled is measured. Assume the distances traveled are normally distributed. The average distance traveled by the 9 Titleist Pro V1 golf balls is 261.1 yards with standard deviation 10 yards, and the average distance traveled by the 9 Callaway Chrome Soft golf balls is 249.3 yards with standard deviation 12 yards.
Which test should the golf pro use to determine if Titleist Pro V1 golf balls travel a longer average distance than Callaway Chrome Soft golf balls?
a. pairedt test for means
b. paredz test for means
c. Ottest for proportions
d. test for means
e. test for means
f. Ottest for proportions
Complete options are;
A) Paired t-test for means
B) Paired Z-test for means
C) Z-test for proportion
D) t-test for means
E) Z-test for means
F) t-test for proportion
Answer:
B) Paired Z-test for means
Step-by-step explanation:
We are told that the distances travelled are normally distributed.
We are also trying to find out if the average distance travelled by the Titleist Pro V1 golf balls is farther than that of the Callaway Chrome Soft golf balls.
Also, the standard deviation of both cases are known.
Thus, this is where Paired Z-test for means is used.
According to the desired test, the correct option is:
a. paired t-test for means
At the null hypothesis, it is tested that ball 1 does not travel farther than ball 2, that is, the subtraction is of at most 0:
[tex]H_0: \mu_1 - \mu_2 \leq 0[/tex]
At the alternative hypothesis, it is tested if it travels farther, that is:
[tex]H_1: \mu_1 - \mu_2 > 0[/tex]
Since we have the standard deviation for the sample, the t-distribution is used.The values tested are greater than 1, hence, the test is for means.There are two samples, hence a paired test is used.Considering the three bullet points above, the correct option is a.

Silicone implant augmentation rhinoplasty is used to correct congenital nose deformities. The success of the procedure depends on various biomechanical properties of the human nasal periosteum and fascia. An article reported that for a sample of 13 (newly deceased) adults, the mean failure strain (%) was 26.0, and the standard deviation was 3.4. (a) Assuming a normal distribution for failure strain, estimate true average strain in a way that conveys information about precision and reliability. (Use a 95% confidence interval. Round your answers to two decimal places.)
Answer:
The 95% confidence interval for the true average strain is between 23.94% and 28.06%.
Step-by-step explanation:
We have the standard deviation of the sample, so we use the t-distribution to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 13 - 1 = 12
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 12 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.18
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.18\frac{3.4}{\sqrt{13}} = 2.06[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 26 - 2.06 = 23.94
The upper end of the interval is the sample mean added to M. So it is 26 + 2.06 = 28.06
The 95% confidence interval for the true average strain is between 23.94% and 28.06%.

Help!!!!!!!!!!!!!!!!
Step-by-step explanation:
The area would be 9 times compared to the area of the original square. To test this, you can let the side of the original square be equal 1. By tripling this side, the side becomes three. Utilizing the area of a square formula, A= s^2, the area of the original square would be 1 after substituting 1 for s. Then, you do the same for the area of the tripled square. With the substitution, the area of the tripled square would be 9. This result displays the area of the tripled square being 9 times as large as the area of the original square. This pattern can be used for other measurements of the square such as:
let s = 2, Original Area= 2^2 = 4 Tripled Area= (2(3))^2 = 6^2= 36. 36/4 = 9
let s = 3, Original Area = 3^2 = 9 Tripled Area - (3(3))^2 = 9^2 =81. 81/9 = 9
let s = 4, Original Area = 4^2 = 16 Tripled Area - (4(3))^2 = 12^2 = 144. 144/16 = 9
let s = 5, Original Area = 5^2 = 25 Tripled Area - (5(3))^2 = 15^2 = 225. 225/25 = 9
let s = 6, Original Area = 6^2 = 36 Tripled Area - (6(3))^2 = 18^2 = 324. 324/36 = 9
let s = 7, Original Area = 7^2 = 49 Tripled Area - (7(3))^2 = 21^2 = 2,401. 2,401/49 = 9
You can continue to increase the length of the square and follow this pattern and it will be consistent.

If the side of a square is tripped how many times will it area be, as compared to the area of the original square?
If the side of a square is tripled then the area would be increased 9 times assuming the goal is to keep the shape a square. Meaning if one side is tripled then all sides are tripled and all corners remain 90 degrees. X being the original length, then 3x is the tripled length. The area of a square is base times height. Where all sides are the same then the area of a square is x squared. Kinda how that term came about. So tripling one side triples all sides. So x times thee times x times three . So x squared times nine is the area of a square who’s side
If the side of a square is tripled, how many times will it’s area be as compared to the area of the original square?
Your question is a little tricky because of the phrase “the side”. Saying “the” side makes it sound like the square has only one when it really has four. It makes it a little difficult to divine your intent, i.e. did you intend for just one side to be tripled in which case the resulting figure would be a rectangle or did you intend for the final figure to still be a square in which case both dimensions would have to be tripled?
In the former case, the area would change by just a factor of 3. In the later, it would change by a factor of 9 as others have
x = square side
x^2 = original area
(3x)^2 = area of square with tripled sides
(3x)^2 / x^2 = 9 - divide the new area with the original one to see how many times larger it is.
The area will be nine times larger.

Answer:
I understand why you are asking about this Ammaria, these type of questions take a lot of understanding of graphing. Please feel ok asking me questions :)
Step-by-step explanation:
we are given two points
P1 = (3,3) in the form (x1,y1)
P2 = (7,11) in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (11-3) / (7-3)
m = 8 / 4
m = 2
now use the slope along with one of the given points, either one will work, i'll use P1 , and put that into the point-slope formula.
y-3 = 2(x-3)
y -3 = 2x -6
y = 2x -3
So with the above formula we can check to see if the points work by plugging them into the formula.
P3 = (5,8)
8 = 2(5) - 3
no point 3 does not work so it's not on the line
P4 = (13, 24)
24 = 2(13) - 3
no point 4 does not work either.
