5 is the answer
here we have hypoteaus and base
so by using pythagoreaus theorem
p^2 = h^2 - b^2
p^2 = 13^2 - 12^2
p^2 = 169 - 144
p^2 = 25
p = root under 25
p = 5
Answer:
5 cm
Step-by-step explanation:
A^2+B^2=C^2
12^2+B^2=13^2
144+B^2=169 (You have to subtract 144 from both sides to get B^2 by its self)
-144 = -144
B^2= 25 (To get rid of the square you have to find the square root)
Square root of 25 = 5cm

A. Events B and C are mutually exclusive because they have different probabilities.

What is a loan amortization schedule?It is defined as the systematic way of representing of loan payments according to the time in which the principal amount and interest are mentioned in a list manner
It is given that:
Cassidy is planning to obtain a loan from her bank for $210,000 for a new home.
A fixed annual interest rate of 2.7% compounded monthly for 15 years.
The formula is:
[tex]P=\rm \dfrac{Fp(i)}{1-(1+i)^{-1}}[/tex]
Plug all the values in the above formula:
[tex]P=\rm \dfrac{210000(2.7\%/12)}{1-(1+(2.7\%/12))^{-15\times12}}[/tex]
After calculating:
P = $1420.11
Thus, Cassidy's approximate monthly payment is $1420.11 if Cassidy is planning to obtain a loan from her bank for $210,000 for a new home.

Use the space below to show clearly how you get your answer.. Single line text.
(4 Points)
Answers
Answer:
Yes. Felix is correct.
Step-by-step explanation:
Find out how much ml does a can of lemonade have, I would assume its 330ml since I searched up the ml of a lemonade can.
Find out how much cans of lemonade there are in 2 packs of 8.
2 packs = 8 x 2 = 16 cans of lemonade
Now find out how much ml 16 lemonade cans equal to.
1 can of lemonade = 330ml
16 cans of lemonade = 330 x 16 = 5280ml
Now let's find 5 bottles of 1 litre.
1 litre x 5 = 5 litres.
5280 = 5 litres and 280ml
So Felix is correct about 2 packs of 8 cans is more than 5 bottles of 1 litre.

A quadrilateral is any shape with four sides. A trapezoid does have four sides, and therefore is a quadrilateral. The difference between a trapezoid and a "regular quadrilateral" is a trapezoid only has one pair of parallel sides, why a quadrilateral like a square or rectangle has two pairs.

C.$528,673.08
D.$217,239.10
Answers
Answer:
PV= $72,866.33
Step-by-step explanation:
Giving the following information:
Interest rate= 6% compounded semiannually
Number of periods= 26*2= 52 semesters
Future value= 338,893
To calculate the initial investment (PV), we need to use the following formula:
PV= FV/(1+i)^n
i= 0.06/2= 0.03
PV= 338,893 / (1.03^52)
PV= $72,866.33
Answer:
The correct answer is $72,866.33

Answers
This question is incomplete, the complete question is;
Nine pieces of 8-in. × 12-in. duct that is 2[tex]\frac{2}{3}[/tex] ft in length is needed for a building. What is the total length (in ft) needed?
Answer:
the total length needed is 24 ft
Step-by-step explanation:
Given the data in the question;
the length of one piece of 8-in. × 12-in. duct is 2[tex]\frac{2}{3}[/tex] ft
Now to find the total length for nine pieces of the duct;
we simple multiply 2[tex]\frac{2}{3}[/tex] ft by nine
so
Total length = 9 × 2[tex]\frac{2}{3}[/tex]
we convert the mixed fraction to improper fraction
2[tex]\frac{2}{3}[/tex] = 8/3
so
Total length = 9 × (8/3) ft
Total length = 24 ft
Therefore, the total length needed is 24 ft

Suppose the variance in trunk diameter of the giant sequoia tree species is 15.7m^2, while the variance in trunk diameter of the California redwood tree species is 10.6m^2. Let x1 represent the average trunk diameter of four randomly sampled giant sequoia trees, and let x2 represent the average trunk diameter of three randomly sampled California redwood trees. If the random sampling is done with replacement, what is the standard deviation σ(x1−x2) of the sampling distribution of the difference in sample means x1−x2 ?
Answers
Answer:
[tex]\mathbf{ \sqrt{\dfrac{15.7}{4} + \dfrac{10.6}{3}} }[/tex]
Step-by-step explanation:
Given that:
[tex]\overline x_1 =[/tex] the average diameter of 4 randomly select sequoia trunk from giant trees
[tex]\overline{x_2}[/tex] = the average diameter of 3 randomly selected trunk in California trees.
Thus;
sample size [tex]\mathbf{n_1 = 4 \ \ \& \ \ n_2 = 3}[/tex]
Variance:
[tex]\mathbf{\sigma_1^2 = 15.7 }[/tex]
[tex]\mathbf{\sigma_2^2 = 10.6 }[/tex]
Recall that:
[tex]\mathbf {( \overline x_1 - \overline x_2) \sim Normal \Big ( \mu_1 -\mu_2 \ , \ \dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_12^2}{n_2} \Big )}[/tex]
[tex]\mathbf{Mean ( \overline x_1 - \overline x_2) = \mu_1 - \mu_2}[/tex]
Therefore:
The standard deviation [tex]\mathbf{ \overline x_1 - \overline x_2 = \sqrt{\dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma_2^2}{n_2} } }[/tex]
[tex]\mathbf{ \overline x_1 - \overline x_2 = \sqrt{\dfrac{15.7}{4} + \dfrac{10.6}{3}} }[/tex]
The standard deviation of the sampling distribution of the difference in the sample means is 9.95
The given parameters are:
Variance: [tex]\sigma_1 ^2 = 15.7[/tex], [tex]\sigma_2 ^2 = 10.6[/tex]Sample size: [tex]n_1 = 4[/tex], [tex]n_2 = 3[/tex].For a normal distribution we have:
[tex]\bar x_1 - \bar x_2 = \sqrt{\frac{\sigma_1^2}{n_1} +\frac{\sigma_2^2}{n_2}}[/tex]
So, the equation becomes
[tex]\bar x_1 - \bar x_2 = \sqrt{\frac{15.7^2}{4} +\frac{10.6^2}{3}}[/tex]
Evaluate the exponents
[tex]\bar x_1 - \bar x_2 = \sqrt{\frac{246.49}{4} +\frac{112.36}{3}}[/tex]
[tex]\bar x_1 - \bar x_2 = \sqrt{61.62+37.45}[/tex]
Evaluate the sums
[tex]\bar x_1 - \bar x_2 = \sqrt{99.07}[/tex]
Evaluate the square roots
[tex]\bar x_1 - \bar x_2 = 9.95[/tex]
Hence, the standard deviation of the sampling distribution of the difference in the sample means is 9.95

¿De qué manera influye la ética en el hombre a partir de su función crítica? Explique.
Answers
Answer:
La ética es una rama de la filosofía que se ocupa de la reflexión crítica sobre las acciones de los hombres. En un sentido general, la ética busca establecer los criterios para juzgar si una acción puede calificarse de correcta o incorrecta, y para evaluar los motivos y consecuencias de dicha acción. Las cuestiones éticas también juegan un papel importante en la política, los negocios y la medicina, y en campos de la ciencia y el estudio como la historia, la biología y la sociología, la ética de la profesión es ocasionalmente un tema de discusión.
Así, la ética implica una evaluación de las acciones de las personas, calificándolas como correctas o incorrectas a los ojos de la sociedad. De esta manera, influye en la forma en que las personas realizan o dejan de realizar una determinada acción, ya que estas consideran sus consecuencias positivas o negativas al momento de realizarla.

What is 12.36 rounded to the nearest whole number
Answers
Answer:
12.
Step-by-step explanation:
This is how to round 12.36 to the nearest whole number. In other words, this is how to round 12.36 to the nearest integer.
12.36 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 12
Fractional Part: 36
Our goal is to round it so we only have an integer part using the following rules:
If the first digit in the fractional part of 12.36 is less than 5 then we simply remove the fractional part to get the answer.
If the first digit in the fractional part of 12.36 is 5 or above, then we add 1 to the integer part and remove the fractional part to get the answer.
The first digit in the fractional part is 3 and 3 is less than 5. Therefore, we simply remove the fractional part to get 12.36 rounded to the nearest whole number as:

Answers
Answer:
A) 0.8131 ≈ 0.81
B) 0.6322 ≈ 0.63
C) 0.7639 ≈ 0.77
Step-by-step explanation:
A)
Total number of units
= 55 + 32 + 17 + 3
= 107
hence the probability that the failure involves a gas leak
= ( 55 + 32 ) / 107
= 0.8131
B) probability that there is evidence of electrical failure given tat there is a gas leak
P ( A / B ) = [tex]\frac{P(A n B)}{P(B)}[/tex]
P( A∩B ) = 55/107 = 0.5140
P ( B ) = ( 55 + 32 ) / 107 = 0.8131
hence P ( A / B ) = 0.5140 / 0.8131 = 0.6322
A = failure due to electrical
B = failure due to gas leak
C) Probability of a gas leak given that there is evidence of electrical failure
P ( B / A ) = [tex]\frac{P(BnA)}{P(A)}[/tex]
P ( B ∩ A ) = 0.5140
P( A ) = ( 55 + 17 ) / 107 = 0.6729
hence P ( B / A ) = 0.5140 / 0.6729 = 0.7639
