A natural number is a positive integer, example, 1,2,5,299 etc.
A rational number is a number that can be expressed as a fraction of integers, such as 245/127, 1/2, 5/1,8/1,...
Since a natural number can be expressed as a fraction of integers, so 

a natural number IS a rational number.

HELP ASAP FOR BRAINLIEST: The mean score for a standardized test is 1700 points. The results are normally distributed with a sta
WITCHER [35]

Answer:

Step-by-step explanation:

Since the results for the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = test reults

µ = mean score

σ = standard deviation

From the information given,

µ = 1700 points

σ = 75 points

We want to the probability that a student will score more than 1700 points. This is expressed as

P(x > 1700) = 1 - P(x ≤ 1700)

For x = 1700,

z = (1700 - 1700)/75 = 0/75 = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

P(x > 1700) = 1 - 0.5 = 0.5

In a rectangle, the perimeter is 102 inches. The width of the rectangle is 9 inch more than half the
Harrizon [31]

perimeter = 2width + 2 length

102 = 2(x+9) + 2x

102 = 2x + 18 +2x

102 = 4x +18

84 = 4x

21 = x

Length = x = 21 inches

Width = x + 9 = 21 + 9 = 30 inches

PLEASE GIVE A GOOD EXPLANATION FOR A FREE BRAINLIEST: 26.8 + 0.65 - 0.028 =
zmey [24]

\boxed{27.422}

We will use order of operations to add and subtract from left to right to solve this equation.

26.8 + 0.65 = 27.45

The equation now looks like:

27.45 - 0.028 = 27.422

Therefore, your answer is 27.422.

Please please help 100 points
stiks02 [169]

We're given

\displaystyle \int_4^{-10} g(x) \, dx = -3

which immediately tells us that

\displaystyle \int_{-10}^4 g(x) \, dx = 3

In other words, swapping the limits of the integral negates its value.

Also,

\displaystyle \int_4^6 g(x) \, dx = 5

The integral we want to compute is

\displaystyle \int_{-10}^6 g(x) \, dx

which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is

\displaystyle \int_{-10}^6 g(x) \, dx = \int_{-10}^4 g(x) \, dx + \int_4^6 g(x) \, dx = 3 + 5 = \boxed{8}
