Mathematics

Answer:

Step-by-step explanation:

Distributive Law:The distributive Property says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.

a×(b+c)= a×b+a×c

commutative property: Commutative property says that we can swap numbers over and still get the same answer.

p×q=q×p

∴d( 10+20)

=d×10+d×20        [using distributive property]

=d×10+20×d         [ using commutative property]

What is the equation, in slope-intercept form,of the line that perpendicular to the line y-4=2/3(x-6) and passes through the poi
Anna35 [415]

Answer:

y = -3/2x + 1

Step-by-step explanation:

Perpendicular slopes are negative reciprocals of each other.

After you convert that equation to slope-intercept form, you can get the negative reciprocal of the slope and put it in the equation. Then, insert the points(-2,-2) in it and solve it to find c. In this case, it's 1.

Answer:

2\sqrt[3]{2}    

Step-by-step explanation:

\sqrt[3]{54} - \sqrt[3]{2}

\sqrt[3]{2 * 3 * 3 * 3} - \sqrt[3]{2}         Prime factorization.

3\sqrt[3]{2} - \sqrt[3]{2}                      Simplify the radical.

It is not always possible to measure every individual in a population; what is the name of the representative group
Scorpion4ik [409]

Answer:

Sample

Step-by-step explanation:

The term that represents the description in the question is called sample.

Take for instance:

  • 40 students selected from a class of 100
  • 1000 people selected from a population of 100000

In the above descriptions:

40 and 1000 represent the samples while 100 and 100000 represent the populations, respectively.

Another example is when 10 cats are picked from an animal farm in order to study their eating pattern.

All these and many more represent sample.

Option 1: y = 5x+5 is the correct answer

Step-by-step explanation:

We can put the values of x in each option one by one and then compare the output to find the best option

So,

<u>For y = 5x+5:</u>

Putting x=1,2,3,4,5...

y = 5(0)+5 = 0+5 = 5\\y = 5(1) +5 = 5+5 = 10\\y = 5(2) + 5 = 10+5 = 15\\y = 5(3) + 5 = 15+5 = 20

The values of x in the function are producing the output values of y, which means that the function for values given in the table is defined by: y= 5x+5

Hence,

Option 1: y = 5x+5 is the correct answer
