Which of the following is a monomial?

A.) 3/x

B.) 5x^2 + 2x + 3

C.) 4x

D.) sqre x-1

Answer:

Here is the answer.

Step-by-step explanation:

b) students are the frequency. so we need to add all the frequency.

5 + 4  + 7 + 10 + 4=30 students

c) here we need to use the summation.

total/ frequency= mean

6*5=30

7*4=28

8*7=56

9*10=90

10*4=40

we need to add them all= 244

total frequency= 30

mean = 244/30= 8.133333333...≈ 8 (this is a rounded of value as  in 0.13, 3 goes on repeating.

Answer:

(2B/m) - k = r

Step-by-step explanation:

B =1/2m(r + k)

Multiply each side by 2

2B =m(r + k)

Divide each side by m

2B/m = m/m (r+k)

2B/m =(r+k)

Subtract k from each side

(2B/m) - k = r+k-k

(2B/m) - k = r

Answer:

Answer:

11 seconds

Step-by-step explanation:

did it on khan

Solution,

Let the price of car be X.

Rate(R)=5%

Here,

Commission % of price of car=32500

or,5% of X=32500

or,5/100*X=32500

or,X=32500*20

X=Rs 650000

Hope it helps

Good luck on your assignment........

Answer:

g(x) = [tex]12.(\frac{3}{4})^x[/tex]

Step-by-step explanation:

Exponential function g has been represented by the table attached,

Equation of the exponential function is,

g(x) = [tex]a.(b)^x[/tex]

Now we substitute the values of x and g(x) from the table,

For a point (0, 12),

12 = [tex]a(b)^0[/tex]

a = 12

For another point (1, 9),

9 = [tex]a.(b)^1[/tex]

9 = a × b

9 = 12 × b

b = [tex]\frac{9}{12}[/tex]

b = [tex]\frac{3}{4}[/tex]

Therefore, equation of the exponential function will be,

g(x) = [tex]12.(\frac{3}{4})^x[/tex]

Answer: +6

Explanation: The equation x² - 36 = 0 is called a quadratic equation because he have a squared term as our highest power.

Our first step in this problem is to get the x²

term by itself by adding 36 to both sides.

That gives us x² = 36.

Next we must get the x by itself and in order to do

that we do the opposite of what is happening to x.

Since x is being squared, the opposite

of squaring is square rooting.

So to get x by itself, we square

root both sides of the equation.

On the left the square root of x² is x and on

the right, remember the following rule.

When square rooting both sides of

an equation, always use plus or minus.

So the answer to this problem would be +6.

So our solution to this equation is +6.

Answer:

£160

Step-by-step explanation:

£160 times 0.6 equals  £96

since  £96 is 60% of the original price since 40% was taken off

The price of the bicycle before decrease is obtained as  £160.

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100. And to convert a fraction or a decimal into percentage, they are multiplied by 100.

The new price of the bicycle is  £96.

And, the percent of decrease is 40%.

Suppose the original price be x.

Then, the following equation can be written for the given case as,

x - 40% × x = 96

⇒ x - 40/100x = 96

⇒ 60/100x = 96

⇒ x = 160

Hence, the original price of the bicycle is given as £160.

Answer:

j < 5

Step-by-step explanation:

=> 10 > j+5

Subtracting both sides by 5, we get

=> 10-5 > j

=> 5 > j

Answer:

1/6

Step-by-step explanation:

an even number has a 1/2 chance of being rolled and a number greater than 4 has a 1/3 chance of getting rolled. multiply 1/2 and 1/3 together and you get 1/6 for your answer.

Answer:

Answer is option C.

Step-by-step explanation:

This is because it does not take into account "random selection" (probability). Thus the mode of selection is biased. The mere fact that a teacher selects his favourite student means the experiment is biased.

Answer:

The answer is A on Edge

Step-by-step explanation:

Answer:

The height will be same in 6 years time

Step-by-step explanation:

Since we do not know the years it would take, we can call this x

Kindly note that 12 inches is 1 feet, so 5 ft would be 60 inches and 10 feet will be 120 inches

Now, the height of tree A after x years would be;

60 + 18x

For tree B, height would be 120 + 8x

Now, we were made to know that they have equal height at the xth year.

Thus;

60 + 18x = 120 + 8x

10x = 120-60

10x = 60

x = 60/10 = 6

Answer:

I think the ship was farther by 40°

Answer:

A proportional relationship is one in which two quantities vary directly with each other.We say the variable varies directly .If y=k.x   then as x increases y  also increases.Here k is called the constant of proportionality.

The given equation y = 4.2x is of the form y=k.x where k= 4.2 as x increases y value will also increase. The relation is called a proportional relationship.
