Answer:

C) 0 ≤ x ≤ 25

Step-by-step explanation:

We are supposed to find a reasonable constraint so that the function is at least 300 i.e. the value of x at which f(x) is greater or equal to 300

A)x ≥ 0

Refer the graph

At x = 0

f(x)=300

On increasing the value of x , f(x) increases but at x = 12 it starts decreasing

So, x ≥ 0 can also have f(x)<300

So, Option A is wrong

B)−5 ≤ x ≤ 30

At x = -5

f(x) = 100

So, Option B is wrong since we require f(x) is greater or equal to 300

c)0 ≤ x ≤ 25

At x = 0

f(x)=300

At x = 12 , it starts decreasing

At x = 25

f(x)=300

So, The value of f(x) is at least 300 when 0 ≤ x ≤ 25

D)All real numbers

At x = 30

f(x)=0

But we require f(x) greater or equal to 300

Hence Option C is true

Answer:

C) 0 ≤ x ≤ 25

Answer:

B

Step-by-step explanation:

The independent value is the number of gallons of gas and the dependent value is the distance traveled, because the distance traveled is affected by how much gas is in the tank.

It is also 250 to 300, because 10 and 12 (numbers of how many gallons of gas are in the tank) multiplied by 25 (miles traveled on one can of gas) equals 250 and 300.

The distance traveled; the number of gallons of gas; 250 to 300 miles; 10 to 12 gallons​. Then the correct option is D.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Tara's car travels about 25 miles on one gallon of gas. She has between 10 and 12 gallons of gas in the tank.

The distance traveled in 10 gallons of gas will be

⇒ 25 x 10

⇒ 250 miles

The distance traveled in 12 gallons of gas will be

⇒ 25 x 12

⇒ 300 miles

The distance traveled; the number of gallons of gas; 250 to 300 miles; 10 to 12 gallons​. Then the correct option is D.

Answer:

∠ b = 12°

Step-by-step explanation:

Complementary angles sum to 90°, thus

a + b = 90 ← substitute a = 78

78 + b = 90 ( subtract 78 from both sides )

b = 12

That is ∠ b = 12°

D- John does not wear his school colors and does not attend any school event.

Description in mathematics, a conjecture is a conclusion or a proposition which is suspected to be true due to preliminary supporting evidence, but for which no proof or disproof has yet been found.

The counter-example for the given conjecture is "John does not wear his school colours and does not attend any school event". Therefore, option D is the correct answer.

The given conjecture is "All students have school pride."

We need to identify a counter-example for the given conjecture.

In mathematics, a conjecture is a conclusion or a proposition that is proffered on a tentative basis without proof. Some conjectures, such as the Riemann hypothesis or Fermat's Last Theorem, have shaped much of mathematical history as new areas of mathematics are developed in order to prove them.

Now, "All students have school pride" is not true, because not all students have school pride.

The counter-example for this conjecture is "John does not wear his school colours and does not attend any school event"

Therefore, option D is the correct answer.

Answer:130.4

Step-by-step explanation:

have good day

x   -  Ram's age now

Ram is half his father's age now, so his father's age is two times Ram's age:

2x  - Ram's father age now

x - 10   -  Ram's age ten years ago

2x - 10    - Ram's father age ten years ago

ten years ago he was one third his father's age so his father's age was three times Ram's age:

2x - 10 = 3•(x - 10)

2x - 10 = 3x - 30

-10 + 30 = 3x - 2x

20 = x

2x = 2•20 = 40

Answer:

Ram is 20 years old now, Ram's father is 40 years old now.

Step-by-step explanation:

Answer:

A. 0

Step-by-step explanation:

In a function, all x-coordinates must be different.

The given function already shows 1, 2, 5, and 8 as x-coordinates, so you must choose a number other than those.

Answer: 0

The correct option will be Option A : the value of k will be 0.

The function is a relation between two sets where one set is called the domain and another set is the codomain which is one one or many one relations.

If the x or input values are different then the relation will become a function.

So we can say if the x values are repeated and their corresponding y or output values are the same, then also the relation becomes a function.

If the x values are repeated and their corresponding y or output values are different, then the relation will not become a function.

Given the ordered pairs are {(1,3), (2, 9), (k, 12), (5,9), (8,0)

As we know the x value is repeated and the y value is different then the relation will not be a function.

So here in the given ordered pair, there is no any second 12. So k value should not be equal to 1,2,5,8 otherwise it will not be a function.

By checking all the options

0 is not present in x value of the given ordered pair.

Therefore the correct option will be Option A : the value of k will be 0.

B) Stem and Leaf plot

Step-by-step explanation:

The purpose of stem and leaf plot is to show the data distribution while retaining its uniqueness. Stem and leaf plot shows the raw values by retaining the original data. It is usually recommended for batches between 15 and 150 data points.

In Stem and Leaf plot, the leaves are usually the last digit of a data, which stems are the remaining digits. For example if we have 2 number suppose 171 and 176, then in stem and leaf plot, as 17 is common, it can be the stem, while last digits of both numbers i.e 1 and 6 are leaves. It can be written as:

17 |  1   6

Answer:

1 in 8 chance.

Step-by-step explanation:

When a coin flips is has two outcomes: heads or tails, obviously.

Whenever you have a 50/50 probability, in this case a coin, every time you add another coin the amount of outcomes squares, or multiplies by the number of outcomes, and since we are using a coin, two. To reiterate, say we were using a die, a die is a cube, a six sided shape, so there are six outcomes. The chances of getting all sixes with one die is 1 in 6. Add another die and try to get all sixes, the chances become 1 in 36. We got this by multiplying our out comes by our outcomes

1 coin: 2 outcomes

2 coins: 4 outcomes

3 coins: 8 outcomes

Another thing:

Don't be fooled by questions being specific by saying "all heads" or "all tails"...

This is a wording trick, no matter the outcome, the chances will always be equal.

Good luck :)
