The transitive property states AB = 4.

The transitive property of equality states that the first number is also equal to the third number if two numbers are equal and the second number is equal to the third number. In other words, if a is equal to b and b is equal to c, then a is equal to c. One of the many mathematical properties of equality is the transitive property.

Given AB = x and x = 4

Acc. to transitive property,

if a = b, b = c Then c = a.

so AB = 4

Hence option D is correct, AB = 4.

Answer:

amount of fabric to make the bag = 4 yards

Step-by-step explanation:

Tara has 1 3/5 yards of fabric . She needs extra 2 1/2 times the amount she have to make a shopping bag. The amount of fabric she needs to make the bag can be calculated as follows.

1 3/5 yards = 8/5 yards of fabrics

What she actually needs to make a shopping bag is two and half the amount she has . Mathematically, it can be express

2 1/2 × 8/5

Let us change 2 1/2 to improper fraction

amount of fabric to make the bag = 5/2 × 8/5

amount of fabric to make the bag = 40/10

amount of fabric to make the bag = 4 yards

Answer:

0.2 Inches

Step-by-step explanation:

Given the height of the saw tooth represented by the function

[tex]y = 0.4sin (15x + 1.5) - 0.2$ for $t > 0.[/tex]

Comparing with the general form of a trigonometric equation

[tex]y = A sin(B(x + C)) + D[/tex]

Where:

Amplitude, A=0.4

Vertical Shift (Midline),D = - 0.2

The maximum and minimum height of the sinusoidal function is given by:

[Min, Max]=[D-A, D+A]

To find the ratio, we simply take the amount of boys and put that number first because that is what they asked for first:

5

Then we find the total amount of the students because that is what they ask for next:

5 boys + 10 girls = 15 students

Finally we take those two numbers and put them in a ratio:

5 : 15

Answer:

x = (rs + t)/(r-s)

Step-by-step explanation:

r(x - s) = sx + t

rx - rs = sx + t

rx - sx = rs + t

x(r - s) = rs + t

x = (rs + t)/(r-s)

The solution for x is x = (t + rs)/(r - s).

A pair of algebraic equations with the equal symbol (=) in the center and the same value are referred to as an equation.

We can begin by simplifying the given equation:

First, solve the parenthesis,

r(x - s) = sx + t

Simplify, the equation, we get,

rx - rs = sx + t

rx - sx = t + rs

Take the like terms to one side, we get,

x(r - s) = t + rs

Now, solve for x, we get,

x = (t + rs)/(r - s)

Therefore, x is equal to (t + rs)/(r - s).

Answer:

Hi there!

The correct answer is C.

Step-by-step explanation:

A polynomial identity  are equations that are true for all possible values of the variable. For example, x²+2x+1=(x+1)² is an identity.

The first two pieces are the same, let each of those equal x, so you have x + x = 2x

The 3rd piece is the sum of the first two + 4, so this would be 2x + 4

Now you have 2x + 2x + 4 = 100 cm

Combine like terms:

4x +4 = 100

Subtract 4 from both sides

4x = 96

Divide both sides by 4

X = 24

First piece is 24 cm

Second piece is 24 cm

Third piece is 52 cm

Correct question:

An urn contains 3 red and 7 black balls. Players A and B withdraw balls from the urn consecutively until a red ball is selected. Find the probability that A selects the red ball. (A draws the first ball, then B, and so on. There is no replacement of the balls drawn).

Answer:

The probability that A selects the red ball is 58.33 %

Step-by-step explanation:

A selects the red ball if the first red ball is drawn 1st, 3rd, 5th or 7th

1st selection: 9C2

3rd selection: 7C2

5th selection: 5C2

7th selection: 3C2

9C2 = (9!) / (7!2!) = 36

7C2 = (7!) / (5!2!) = 21

5C2 = (5!) / (3!2!) = 10

3C2 = (3!) / (2!) = 3

sum of all the possible events = 36 + 21 + 10 + 3 = 70

Total possible outcome of selecting the red ball = 10C3

10C3 = (10!) / (7!3!)

         = 120

The probability that A selects the red ball is sum of all the possible events divided by the total possible outcome.

P( A selects the red ball) = 70 / 120

                                         = 0.5833

                                         = 58.33 %

Answer: 59

Step-by-step explanation:

On 15th day Kyle will do 59 crunches.

An equation is a statement that consists of algebraic expressions equated with other algebraic expressions by an equal sign.

The crunches Kyle did on Day 1 are 3

The rate by which he is increasing per day is 4 crunches/per day

let t represent the number of days

Let the number of crunches on t day be y

Then the equation formed will be

y = 3 + 4(t-1)

On 15th day, he will do

y = 3+ (15-1) *4

y = 3+56

y = 59

Therefore, on 15th day Kyle will do 59 crunches.

Answer:

90% confidence interval for the true population mean textbook weight is [35.79 ounces , 38.21 ounces].

Step-by-step explanation:

We are given that you measure 50 textbooks' weights, and find they have a mean weight of 37 ounces.

Assume the population standard deviation is 5.2 ounces.

Firstly, the Pivotal quantity for 90% confidence interval for the population mean is given by;

                           P.Q. =  [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]  ~ N(0,1)

where, [tex]\bar X[/tex] = sample mean weight = 37 ounces

           [tex]\sigma[/tex] = population standard deviation = 5.2 ounces

           n = sample of textbooks = 50

           [tex]\mu[/tex] = true population mean textbook weight

Here for constructing 90% confidence interval we have used One-sample z test statistics as we know about population standard deviation.

So, 90% confidence interval for the population mean, [tex]\mu[/tex] is ;

P(-1.645 < N(0,1) < 1.645) = 0.90  {As the critical value of z at 5%

                                            level of significance are -1.645 & 1.645}  

P(-1.645 < [tex]\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex] < 1.645) = 0.90

P( [tex]-1.645 \times {\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]{\bar X-\mu}[/tex] < [tex]1.645 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ) = 0.90

P( [tex]\bar X -1.645 \times {\frac{\sigma}{\sqrt{n} } }[/tex] < [tex]\mu[/tex] < [tex]\bar X +1.645 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ) = 0.90

90% confidence interval for [tex]\mu[/tex] = [ [tex]\bar X -1.645 \times {\frac{\sigma}{\sqrt{n} } }[/tex] , [tex]\bar X +1.645 \times {\frac{\sigma}{\sqrt{n} } }[/tex] ]

                                          = [ [tex]37-1.645 \times {\frac{5.2}{\sqrt{50} } }[/tex] , [tex]37+1.645 \times {\frac{5.2}{\sqrt{50} } }[/tex] ]

                                          = [35.79 , 38.21]

Therefore, 90% confidence interval for the true population mean textbook weight is [35.79 ounces , 38.21 ounces].
