Answer:

C) -8-11x-2.

Step-by-step explanation:

First solve the expression,

-2(4 - 3x)+(5x-2) = 11x-10

A) 11x-10 = 11x-10

B) -8+11x -2 = 11x-10

C) -8-11x-2 does not equal 11x-10. Instead -8-11x-2 = -11x-10

D) -8+6x+5x-2 = 11x-10

Answer:

C.Both answers A and B are true.

Step-by-step explanation:

My teacher told me that was right.

Both answer A and B are true about the Pythagorean Theorem.

Here,

We have to find about the Pythagorean Theorem and its converse.

What is Pythagorean Theorem?

Pythagorean Theorem is well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

Now,

In option A;  

It states about the Pythagorean Theorem,

Pythagorean theorem is well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

Hence, option A is true.

In the option B; converse of Pythagoras theorem states that;

If the square of a side is equal to the sum of the square of the other two sides, then triangle must be right triangle.

Hence option B is true.

Clearly, Both answer A and B are true about the Pythagorean Theorem.

Answer: 2 independent sample test of proportions

Step-by-step explanation:

The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.

In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.

The kind of analysis that would be most adequate for the given study:

Test of 2 Independent Proportions.

The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.

In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.

In the given situation, the samples of males and females are random and permitted to stay free("continue after the mission") and evaluated after a time to take the deduction.

Step-by-step explanation:

Complete question

A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius. WHAT IS THE INITIAL temperature of the coffee

The initial temperature occurs at x = 0

Substitute x = 0 into the expression;

T=70(0.80)^x+20

T =70(0.80)^0+20

Since any value raise to power of zero is 1, hence;

T = 70(1)+20

T = 70+20

T = 90 degree Celsius

Hence the initial temperature of the coffee is 90 degrees

The initial temperature of the coffee is 90 degrees.

The function is represented as:

[tex]\mathbf{T = 70(0.80)^x + 20}[/tex]

At the initial temperature, x = 0.

So, we have:

[tex]\mathbf{T = 70(0.80)^0 + 20}[/tex]

Expand

[tex]\mathbf{T = 70 \times 1 + 20}[/tex]

Multiply

[tex]\mathbf{T = 70 + 20}[/tex]

Add

[tex]\mathbf{T = 90}[/tex]

Hence, the initial temperature of the coffee is 90 degrees.

Given:

The given figure represents the original parallelogram and the reduction.

To find:

The length of side A in the new parallelogram.

Solution:

We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.

The corresponding sides of similar figures are proportional.

[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]

[tex]45\times A=5\times 18[/tex]

[tex]45A=90[/tex]

Divide both sides by 45.

[tex]A=\dfrac{90}{45}[/tex]

[tex]A=2[/tex]

The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.

Answer:

Y= -2/5X

Step-by-step explanation:

the equation is y=mx + b

slope: -2/5x

y- intercept: 0

all you do is combined your slope and y-intercept together: Y= -2/5X , you dont need to add +0 because it gonna just still be the same as y= - 2/5x

Y= -2/5X or y= -2/5x + 0 is the same so it can be any of these 2 that you pick but the correct way is y= -2/5x

Step-by-step explanation:

First of all, figure out what you're trying to model. Second, decide what variable name you want to use to model it. Third, write the relationship expressed in the English statement.

Here, we're modeling the number of balls in the box. We choose 'b' to represent that number. We are told it is greater than 12, so our model is ...

  b > 12

25a² - 16b²

25*-2² - 16*3²

25*4 - 16*9

100 - 144

12b + 39c = -72 --(3)

(3)-(2)

12b + 39c - 12b + 5c = -72-16

Answer:

Event B has the smallest probability and Even C has the greatest probability

Step-by-step explanation:

There are more odd number greater than 50 than odd numbers less than 20

So the probability of selecting an odd number greater than 50 is greater than the probability of selecting an odd numbers less than 20

There are more even numbers than odd numbers greater than 50

So the probability of selecting an even number is greater than the probability of selecting an odd number greater than 50

Wrap up:  Event B has the smallest probability and Even C has the greatest probability

Step-by-step explanation:

60% = 0.6

15% = 0.15

10 = 0.15

Answer:

24

Step-by-step explanation:

Let x represent total number of vehicles

Let T represent number of trucks

Let V represent number of vans

Let B represent number of buses

Convert percent's to decimals:

60% = 0.6

15% = 0.15

Set up equations:

T = 0.6x

V= 0.15x

B= (1 - 0.6 - 0.15)x

For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%

Since we know there are 10 buses, set B=10

B= (1 - 0.6 - 0.15)x

10= (1 - 0.6 - 0.15)x

10= 0.25 x

Divide both sides by 0.25 so that we get:

10/0.25 = x

x= 40

We now know there are 40 vehicles present.  To find the number of trucks, we take 60% of the total number of vehicles

T = 0.6x

T= 0.6 (40)

T= 24

Therefore there are 24 trucks.
