3x+6=36 ?????? ???????

Answer:

-3(43)= -129

−3(3) = −9

−3(2) = −6

−3(1) = −3

−3(0) = 0

−3(−1) = 3

−3(−2) = 6

 -3(-3)= 9

Step-by-step explanation:

As the factor decreases by 1, the product increases by 3. So −3(−1) = 3, −3(−2) = 6.

Multiplying −3 by a negative integer gives a positive number. 

The product of a positive number and a negative number is negative.

Step-by-step explanation:

43=0.34x+19.5

=> 0.34x+19.5 = 43

=> 0.34x = 43 - 19.5

= 23.5

[tex] = > x = \frac{23.5}{0.34} [/tex]

To find the answer, simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

Step-by-step explanation:

3x+2x+10=180

5x+10=180

5x=170

x=34

so the value of x is 34

The value of x is 34.

Here,

Angle 1 and angle 2 are supplementary.

And, angle 1 measures 3x and angle 2 measures 2x + 10.

We have to find the value of x.

What is Supplementary angle?

Supplementary angles are those angles that sum up to 180 degrees.

Now,

Angle 1 and angle 2 are supplementary.

⇒ ∠1 + ∠2 = 180°

And, angle 1 measures 3x and angle 2 measures 2x + 10.

⇒ 3x + 2x + 10 = 180

⇒ 5x + 10 = 180

⇒ 5x = 170

⇒ x = 34

Hence, The value of x is 34.

Answer:

65 meters

Step-by-step explanation:

The height of the monument off the ground = x + 5

Find x using Pythagorean Theorem:

x = √(61² - 11²)

x = √3,600

x = 60 meters

Height of the monument off the ground = x + 5 = 60 + 5 = 65 meters

Answer: 65

Word Problem:  A Monument in the shape of a right triangle sits on a            rectangular pedestal that is 5 meters high and 11 meters long. The longest side of the Triangular monument measures 61 meters.

Question: How high off the ground is the top of the monument?

Answer:

0.84 = 84% probability that the calculator has a good case and good batteries.

Step-by-step explanation:

We have these following percentages:

8% of a certain batch of calculators have a defective case.

11 % have defective batteries.

3% have both a defective case and defective batteries.

Using Venn Diagrams:

Event A: Defective Case

Event B: Defecitve Battery

So the probabilities are: [tex]P(A) = 0.08, P(B) = 0.11, P(A \cap B) = 0.03[/tex]

Probability of at least one problem:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.08 + 0.11 - 0.03 = 0.16[/tex]

Find the probability that the calculator has a good case and good batteries.

No problems, so

[tex]p = 1 - P(A \cup B) = 1 - 0.16 = 0.84[/tex]

0.84 = 84% probability that the calculator has a good case and good batteries.

The probability that the calculator has a good case and good batteries is 0.84 or 84%

Since

8% of a certain batch of calculators have a defective case.

11 % have defective batteries.

3% have both a defective case and defective batteries.

So, the probability is

=  1- (0.08 + 0.11 - 0.03)

= 1 - 0.16

= 0.84

Therefore, The probability that the calculator has a good case and good batteries is 0.84 or 84%

Answer: the equation represents an addictive relationship

Step-by-step explanation:

Step-by-step explanation:

2x-3y= -14

5x+9y= -2

multiply the first one by 5 and the second one by -2 to get equal and opposite value of x.

➡️when you multiply,it will be

10x-15y= -70

-10x-18y= 4

cancel out each x value,then you get

-15y-18y= -70+4

-33y= -66, divide each side by -33 to get the value of y

⚪️y= 2

➡️substitute the value of y in the equation of (2x-3y= -14) to find the value of x

2x-3(2)= -14

2x-6= -14

2x= -14+6

2x= -8 divide both side by 2

⚪️x= -4

so the answer is (-4,2)

Answer:

[tex]p-value = 0.9953[/tex]

Step-by-step explanation:

Given

[tex]P = 40\%[/tex] --- proportion of population

[tex]n = 200[/tex] -- samples

[tex]p = 31\%[/tex] -- proportion of samples

Required

Determine the p value

First, calculate the standard deviation ([tex]\sigma[/tex])

[tex]\sigma = \sqrt{\frac{P*(1 - P)}{n}}[/tex]

[tex]\sigma = \sqrt{\frac{40\%*(1 - 40\%)}{200}}[/tex]

[tex]\sigma = \sqrt{\frac{0.40*(1 - 0.40)}{200}}[/tex]

[tex]\sigma = \sqrt{\frac{0.40*0.60}{200}}[/tex]

[tex]\sigma = \sqrt{\frac{0.24}{200}}[/tex]

[tex]\sigma = \sqrt{0.0012}[/tex]

[tex]\sigma = 0.0346[/tex]

Next, we calculate the z score

[tex]z = \frac{p - P}{\sigma}[/tex]

[tex]z = \frac{40\% - 31\%}{0.0346}[/tex]

[tex]z = \frac{9\%}{0.0346}[/tex]

[tex]z = \frac{0.09}{0.0346}[/tex]

[tex]z = 2.6012[/tex]

[tex]z \approx 2.60[/tex]

From the z table, the p value of [tex]z = 2.60[/tex] is: 0.9953

Hence:

[tex]p-value = 0.9953[/tex]

[tex]k = 2.5[/tex]

Step-by-step explanation:

Given

[tex]A = (4,2)[/tex]

[tex]A' = (10,5)[/tex]

[tex]B = (10,6)[/tex]

[tex]B' = (25,15)[/tex]

Required

Determine the scale factor (k)

Scale factor is calculated using:

[tex]Old * k = New[/tex]

In this case, we have:

[tex]AB* k = A'B'[/tex]

Make k the subject

[tex]k = \frac{A'B'}{AB}[/tex]

Using point A and A'

[tex]k = \frac{A'}{A}[/tex]

[tex]k = \frac{(10,5)}{(4,2)}[/tex]

Factorize the numerator

[tex]k = \frac{2.5(4,2)}{(4,2)}[/tex]

[tex]k = 2.5*\frac{(4,2)}{(4,2)}[/tex]

[tex]k = 2.5*1[/tex]

[tex]k = 2.5[/tex]

Answer:

Step-by-step explanation:

The percent error in the given situation is 2%. Therefore, option C is the correct answer.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, Oliver tries to cut a piece of metal 30 centimeters long the metal ends up being 29.4 centimeters long.

Difference in number =30-29.4

= 0.6

Now, percent error = 0.6/29.4 ×100

= 2.04%

≈ 2%

The percent error in the given situation is 2%. Therefore, option C is the correct answer.

Answer:

0.74

Step-by-step explanation:

Given :

__________________ STRENGTH __

__________________High _ Low

High conductivity _____ 74 __ 8

Low conductivity _____ 15 ___ 3

Probability that conductivity is high and strength is high :

This the probability of High conductivity n High strength = P(High conductivity n High strength)

Probability = required outcome / Total possible outcomes

Required outcome = P(High conductivity n High strength) = 74 (from table)

Total possible outcomes = total sample size = 100

Hence,

P(High conductivity n High strength) = 74 / 100 = 0.74
