Answer:

In English -

The legs are the sides opposite the acute angles of a right triangle. The legs are the lesser sides of the right triangle. The hypotenuse is the longest side of the right triangle.

In Spanish -

Los catetos son los lados opuestos a los ángulos agudos de un triángulo rectángulo. Los catetos son los lados menores del triángulo rectángulo. La hipotenusa es lado mayor del triángulo rectángulo.

Answer:

area of the square is 16 inches

area of the square = perimeter of the square

Step-by-step explanation:

each side of the square is 4" so

A = 4 x 4 or 16 sq in

P = 4 + 4 + 4 + 4 = 16 in

We'll use the exponent rule that a^(b+c) = a^b*a^c

to break up 17^16 into 17^(14+2) = 17^14*17^2

That allows us to factor like so

17^16+17^14

17^14*17^2+17^14*1

17^14(17^2 + 1)

Computing 17^14 is a lot more difficult compared to computing 17^2 + 1, assuming you only could use paper and pencil.

Note that 17^2 = 17*17 = 289, so 17^2 + 1 = 289+1 = 290

Because 290 ends in a 0, this means that 5 is a factor

290 = 5*58

This makes 5 to be a factor of the original expression.

----------------

So overall,

17^16+17^14 = 17^14(17^2 + 1) = 17^14*290 = 17^14*5*58 = 5*17^14*58

The stuff "17^14*58" doesn't matter. All we care about is that factor of 5.

Since 5 is a factor, this means that 17^16+17^14 is a multiple of 5, or 17^16+17^14 is divisible by 5.

Phrased another way, 17^16+17^14 all divided over 5 leads to some integer. In this case, the integer would be the result of 17^14*58.

Answer:

E) An observational study using a stratified sample.

Step-by-step explanation:

This study is not an experiment because the customers were not subjected to any treatment but just observation from those selected. Also, the sampling method used was stratified sampling because we see that random samples were selected independently from two unique populations which are population of those that purchased computers and those that offer tech support.

Therefore the correct option is E.

Answer:

7/6

5/4

Step-by-step explanation:

Answer:

3/4

Step-by-step explanation:

We have two fractions, 1/4 and 3/4. Lucky they have the same denominator :

Which is the number under the line, which means their capacity is the same amount. Now we just have to see the greater numerator (the number above the line).

So since 3 is greater than 1

Therefore 3/4 is the answer

Answer:

You answer would be 3/4

Step-by-step explanation:

3/4 is larger than 1/4.

Answer:

The change to the face 3 affects the value of P(Odd Number)

Step-by-step explanation:

Analysing the question one statement at a time.

Before the face with 3 is loaded to be twice likely to come up.

The sample space is:

[tex]S = \{1,1,2,2,2,3\}[/tex]

And the probability of each is:

[tex]P(1) = \frac{n(1)}{n(s)}[/tex]

[tex]P(1) = \frac{2}{6}[/tex]

[tex]P(1) = \frac{1}{3}[/tex]

[tex]P(2) = \frac{n(2)}{n(s)}[/tex]

[tex]P(2) = \frac{3}{6}[/tex]

[tex]P(2) = \frac{1}{2}[/tex]

[tex]P(3) = \frac{n(3)}{n(s)}[/tex]

[tex]P(3) = \frac{1}{6}[/tex]

P(Odd Number) is then calculated as:

[tex]P(Odd\ Number) = P(1) + P(3)[/tex]

[tex]P(Odd\ Number) = \frac{1}{3} + \frac{1}{6}[/tex]

Take LCM

[tex]P(Odd\ Number) = \frac{2+1}{6}[/tex]

[tex]P(Odd\ Number) = \frac{3}{6}[/tex]

[tex]P(Odd\ Number) = \frac{1}{2}[/tex]

After the face with 3 is loaded to be twice likely to come up.

The sample space becomes:

[tex]S = \{1,1,2,2,2,3,3\}[/tex]

The probability of each is:

[tex]P(1) = \frac{n(1)}{n(s)}[/tex]

[tex]P(1) = \frac{2}{7}[/tex]

[tex]P(2) = \frac{n(2)}{n(s)}[/tex]

[tex]P(2) = \frac{3}{7}[/tex]

[tex]P(3) = \frac{n(3)}{n(s)}[/tex]

[tex]P(3) = \frac{1}{7}[/tex]

[tex]P(Odd\ Number) = P(1) + P(3)[/tex]

[tex]P(Odd\ Number) = \frac{2}{7} + \frac{1}{7}[/tex]

Take LCM

[tex]P(Odd\ Number) = \frac{2+1}{7}[/tex]

[tex]P(Odd\ Number) = \frac{3}{7}[/tex]

Comparing P(Odd Number) before and after

[tex]P(Odd\ Number) = \frac{1}{2}[/tex] --- Before

[tex]P(Odd\ Number) = \frac{3}{7}[/tex] --- After

We can conclude that the change to the face 3 affects the value of P(Odd Number)

Answer:

A

Step-by-step explanation:

because you dont have a chance

Answer:

Novels: 24% Comics: 76%

Step-by-step explanation:

Divide 18/75= 0.24= 24% to find percent of novels

Subtract 100-24= 76 to get the remaining percent

Or

Subtract 75-18= 57 (to get the number of comics she has)

Divide 57/75= 0.76= 76% to find percent of comics

Answer:

b) 2 20/100

Step-by-step explanation:

2.20 = 2 2/10

so, if that fraction is multiplied by 10/10 then it's still the same.

Answer: Not here is the answer

Step-by-step explanation:

To write 2.20 as a fraction you have to write 2.20 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

2.20 = 2.20/1 = 22/10

And finally we have:

2.20 as a fraction equals 22/10

Answer:

66

Step-by-step explanation:

Since the triangels are similar, 3x+18=4x+2.

Let's solve that.

3x+18=4x+2

16=x

THIS IS NOT THE VALUE OF THE ANGLE! We have to plug x into one of the equations to find the answer.

3(16)+18=66

Answer:

57.5

Step-by-step explanation:

if you break it down into smaller shapes, there's a semicircle, three triangles and a rectangle.

circle πr² = π 2² = 4π² = 39.5

triangle 1 bh = (3)(2) = 6

triangle 2 bh = (4)(1) = 4

triangle 3 bh = (2)(4) = 8

Add them all up to get total area

6 + 4 + 8 + 39.5 = 57.5

Answer: 0.4 >-8 /9(8+7)

Answer:

x = 8, so 6x = 48 and 4x + 10 = 42

Step-by-step explanation:

This is a right angle, so we can say that 6x + 4x + 10 = 90 = 10x + 10 = 90 = 10x = 80 = x = 8.

the answer to your question might be (B).

Answer:

On a coordinate plane, triangle A B C has points (negative 6, 6), (6, 6), (6, negative 6). On a coordinate plane, triangle A prime B prime C prime has points (negative 2, 2), (2, 2), (2, negative 2).

Answer:

y=2x-10

Step-by-step explanation:

First change to equation into slope intercept form

2y=-x+6

y=-1/2x+3

slope=2 (beacause it is perpendicular)

y--4=2(x-3)

y+4=2x-6

y=2x-10

Answer:

Step-by-step explanation:

The null and the alternative can be computed as:

[tex]H_o : \mu = 7.62[/tex]

[tex]H_1 : \mu < 7.62[/tex]

[tex]Claim: \mu < 7.62[/tex]

[tex]\alpha= 0.05[/tex]

The critical value for a left-tailed test at [tex]\alpha= 0.05[/tex] = -1.645

The test statistics can be computed as:

[tex]Z = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}} }[/tex]

[tex]Z = \dfrac{6.78 - 7.62}{\dfrac{1.77}{\sqrt{54}} }[/tex]

[tex]Z = -3.487[/tex]

The P-value = (Z< -3.487)

The P-value = 0.00024

Decision Rule: TO reject [tex]\mathbf{H_o}[/tex] at [tex]\alpha= 0.05[/tex], if test statistics is less than the critical value (left tailed)

Conclusion: We reject  [tex]\mathbf{H_o}[/tex] at ∝ = 5%, thus there is enough evidence to support the claim that the college students average daily ownership expenses are less than the national average.

Step-by-step explanation:

Answer: 336 different ways

Step-by-step explanation:

Ok, we have a total of 8 horses, and we have 3 places.

First, second, third.

The total number of combinations will be equal to the product of the number of possible options that we have in each place.

For the first place, we could have any of the 8 horses, so there are 8 possible options.

For the second place, we will have 7 horses (because one is already in the first place) then here we have 7 options.

For the third place, we will have 6 horses (because one is in the first place and another is in second place) then here we have 6 options.

The total number of different ways in which the horses can finish is:

C = 8*7*6 = 336 different ways
