Hello,

Step-by-step explanation:

[tex]|AD|^2=(3-(-1))^2+(0-(-1))^2=16+1=17\\\\|AB|^2=1^2+3^2=10\\\\\boxed{Perimeter=2*\sqrt{17} +2*\sqrt{10}}[/tex]

Answer:

2*√10 + 2*√17

Step-by-step explanation:

In order to find the perimeter we must find the length of each side

To find the length of the sides we must use the distance formula

Distance formula:

d = √ ( x2 - x1 )² + ( y2 - y1 )²

Where the x and y values are derived from the points of each side

First let's find the length of AB

Coordinates of A: (-1,-1)

Coordinates of B: (0,2)

* Define variables *

( Remember coordinates are written as (x,y))

x1 = -1

x2 = 0

y1 = -1

y2 = 2

Now to find the length of AB we simply plug in the values of x and y into the distance formula

d = √ ( x2 - x1 )² + ( y2 - y1 )²

x1 = -1, x2 = 0, y1 = -1, y2 = 2

* Plug in values *

d = √(0 - (-1))² + (2 - (-1))

If there are two negative signs in front of a number then the two negative signs cancel out and the sign changes to +

d = √(0+1)² + (2+1)²

Simplify addition

d = √(1)² + (3)²

Apply exponents

d = √1 + 9

Simplify addition

d = √10

So the length of AB is √10

One of the properties of a parallelogram is that the opposite sides are congruent.

So the opposite side of AB (CD) is also equal to √10

Next we need find the length of AD

We use the same process we used for finding the length of AB

Coordinates of A: (-1,-1)

Coordinates of D: (3,0)

*Define variables*

x1 = -1

x2 = 3

y1 = -1

y2 = 0

Plug in the values of x and y into the formula ( formula is d = √ ( x2 - x1 )² + ( y2 - y1 )² )

*Plug in the values of x and y )

d = √( -1 - 3 )² + ( 0 - (-1)²

Simplify subtraction and addition

d = √(-4)² + (1)²

Apply exponents

d = √16 + 1

Add

d = √17

So the length of AD is √17

Like stated previously opposite sides in a parallelogram are congruent so the opposite side of AD (BC) also has a length of √17

Now to find the perimeter,

The perimeter is the sum of the side lengths

Side lengths of the parallelogram shown:

AB = √10

BC = √17

CD = √10

DA = √17

Perimeter = √10 + √17 + √10 + √17 = 2*√10 + 2*√17

Answer:

Step-by-step explanation:

Let J and M represent the current ages of Jacob and his Mother.

currently:

  M = 3 +9J

in 11 years:

  M+11 = 5 +3(J+11)

Using the first equation to substitute for M in the second, we have ...

  (3 +9J) +11 = 5 +3(J +11) . . . . . substitute for M

  9J +14 = 3J +38 . . . . . . simplify

  6J + 24 . . . . . . . . . . subtract 3J+14

  J = 4 . . . . . . . . . . divide by 6

  M = 3 +9(4) = 39

Jacob is 4 and his mother is 39.

Answer:

24[tex]\sqrt{3}[/tex]

Step-by-step explanation:

KML is a special right triangle with angle measures of 90-60-30 and side lengths represented by 2a-a[tex]\sqrt{3}[/tex]-a

|KL| is given as 48 so 2a = 48 and a = 24

ML is the side length that sees angle measure 60 so it's represented with a[tex]\sqrt{3}[/tex]

since a = 24

a[tex]\sqrt{3}[/tex] = 24[tex]\sqrt{3}[/tex]

Answer:

9y+1=32y+1+54

collect like terms, a symbol changes once it crosses the equal to sign =

9y-32y=1+54-1

-23y=54

divide both sides by -23

-23y/-23=54/-23

-23 will cancel -23 to give y

y=54/-23

y=-2.4 or 2 whole number 8/23

Answer: y is -54/23

Step-by-step explanation:

==========================================================

Explanation:

We have a triangle with these three sides.

Use the pythagorean theorem to find b

a^2+b^2 = c^2

b = sqrt(c^2 - a^2)

b = sqrt(82^2 - 80^2)

b = sqrt(324)

b = 18

This is the missing vertical leg of the triangle. And this is also the side opposite angle C.

We have enough information to compute the sine of the angle.

sin(angle) = opposite/hypotenuse

sin(C) = AB/AC

sin(C) = 18/82

sin(C) = (9*2)/(41*2)

sin(C) = 9/41

Answer:

<ADC=90

therefore AC= 20 using Pytagoras

BAC is a right angle triangle because it belongs to the Pytagoras theorem:25,20,15 i.e 25²=15²+20²

3) I DON'T THINK PQR IS A RIGHT ANGLE TRIANGLE because it doesn't belong to the Pytagoras triple.

Answer:

B

Step-by-step explanation:

we have a formula of volume:

V= 4/3*pi*R^3 = 4/3*3.14*(18/2)^3 = 3052.08

Answer:

y = -3/4(x+4)

Step-by-step explanation:

The point slope formula is given by

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is a point on the line

y-0 = -3/4(x - -4)

y = -3/4(x+4)

Answer:

.14

Step-by-step explanation:

The relative frequency that favors football is around 0.14, or 14%.

Given that Phoebe took a survey of her classmates' favorite sport.

We need to find the relative frequency of survey members who prefer football,

Preferred sports =

Football    baseball     basketball    tennis       others     total

     4              5                     8                 7              4          28

To calculate the relative frequency of survey members who prefer football, you need to divide the number of people who prefer football by the total number of survey respondents.

According to the table, the number of people who prefer football is 4, and the total number of respondents is 28.

Relative Frequency = Number of people who prefer football / Total number of respondents

= 4 / 28

≈ 0.14

Therefore, the relative frequency of survey members who prefer football is approximately 0.14 or 14%.

Answer:

126 Students

Step-by-step explanation:

First, you subtract the money from the adult tickets from the total ($880), that leaves $630.

Since each student ticket is $5, you divide $630 by 5, which equals 126.

So, 126 students attended.

Answer:

126

by-step explanation:

880 is that amount made in total.

250 were adults.

we can subtract that to simplify; 880-250= 630

Knowing that information we can assume the rest of the tickets are students.

5$ each.

5/620

How many 5s go into 630? 126.

Check your answer by multiplying 126 by 5, which = 630.

630+250=880.

Using the binomial distribution, it is found that:

0.3677 = 36.77% probability that more than 1 of these parts are defective.

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

For each part, there are only two possible outcomes. Either they are defective, or they are not. The probability of a part being defective is independent of any other part, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of a success.

At a certain auto parts manufacturer, the Quality Control division has determined that one of the machines produces defective parts 18% of the time.

This means that [tex]p = 0.18[/tex]

A random sample of 7 parts produced by this machine is chosen.

This means that [tex]n = 7[/tex]

Find the probability that more than 1 of these parts are defective.

This is:

[tex]P(X \geq 1) = 1 - P(X < 1)[/tex]

In which

[tex]P(X < 1) = P(X = 0) + P(X = 1)[/tex]

Thus

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{7,0}.(0.18)^{0}.(0.82)^{7} = 0.2493[/tex]

[tex]P(X = 1) = C_{7,1}.(0.18)^{1}.(0.82)^{6} = 0.3830[/tex]

Then

[tex]P(X < 1) = P(X = 0) + P(X = 1) = 0.2493 + 0.3830 = 0.6323[/tex]

[tex]P(X \geq 1) = 1 - P(X < 1) = 1 - 0.6323 = 0.3677[/tex]

0.3677 = 36.77% probability that more than 1 of these parts are defective.

Explanation:

1/6 of the total number of cartons are small. We have 264 total cartons, so,

1/6 of 264 = (1/6)*264 = 44

We need 44 small cartons.

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

2/3 of the total cartons are medium, so,

2/3 of 264 = (2/3)*264 = 176

There are 176 medium cartons.

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

So far we calculated there are 44+176 = 220 cartons from the small and medium sizes.

This must mean there are 264 - 220 = 44 large cartons
