Answer:

The interval that would represent the middle 99.7% of IQ scores is (55, 145).

Step-by-step explanation:

The empirical rule tells us that 68% of values are within one standard deviation from the mean, 95% of values are within two standard deviations from the mean, and 99.7% of values are within three standard deviations from the mean.

If we want to determine the interval representing the middle 99.7% of IQ scores, we need to determine the values that are three standard deviations from the mean.

We are given the standard deviation of 15 and a mean of 100. Three standard deviations from the mean can be calculated as such:

The interval that represents the middle 99.7% of IQ scores is (55, 145).

Answer:

$35 = $12 + $1.85x

Step-by-step explanation:

the total is 35 so it is alone on the left side of the equal sign

then 5 + 7 is 12 and he has to spend $12

rides are 1.85 each so there is a x next to it

Answer:

-7x^2+4x+6

Step-by-step explanation:

Make sure your distributing the minus to make -4x and -3 from negative to postive, then just combine like terms ^^ you should be good!

Answer:

The equation of the line is: y=2x + 3

Both functions g(x) and f(x) are positive in the interval of (1, ∞). Then the correct option is C.

The domain is the set of values for which the given function is defined.

The range is the set of all values which the given function can output.

When comparing the f(x) = x² – x and g(x) = log(2x + 1).

For f(x), we have

f(x) = x² – x

f(x) = x² – x + 1/4 - 1/4

f(x) = (x - 1/2)² - 1/4

The domain and the range of the function f(x) will be (-∞, ∞) and (-5, ∞).

For g(x), we have

g(x) = log(2x + 1)

The domain and the range of the function g(x) will be (-1/2, ∞) and (-∞, ∞).

Both functions g(x) and f(x) are positive in the interval of (1, ∞). Then the correct option is C.

More about the domain and range link is given below.

Boys/Girls = 13/17

Answer: If you meant (x^2 + 5x - 36)/(x^2-16) then the answer is: (x+9)/(x-4)

Step-by-step explanation:

This is just factoring, you can use guess and check.

If you take just the numerator: x^2+5x-36 and factor. To factor consider -36, and the multiples that can add up to 5 (from 5x).

x^2 + 5x - 36/(x^2-16)

The denominator is actually a rule of (a+b)(a-b) which in this case (x+4)(x-4)

(x+9)(x-4)/(x-4)(x+4)

Now just divide like terms which is the (x-4)/(x-4)=1

(x+9)/(x+4)

Hey there!

PEMDAS simply means (the OVERALL question answer)

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

Here’s an example

24 - 4^2 + 2 * 4

= 24 - 16 + 2 * 4

= 24 - 16 + 8

= 8 + 8

= 16

Thus, the answer for that equation is: 16

Often people remember PEMDAS by saying. (So, I’d advise you think of it like that way as well!)

PEMDAS is the order that you solve a problem.

PEMDAS stands for:

Parenthesis

Exponents

Multiplication and Division

Addition and Subtraction

If you have an equation or expression that you need to solve, you solve it in this order. You do the parenthesis first, then you solve the exponents, then you do the multiplication and division from left to right, and last you do addition and subtraction from left to right.

In the equation

2 + 3 * 5,

first you would do 3 * 5 because multiplication is before addition.

2 + 15

Then you would do the addition to get the answer:

17.

Answer:

Yes, it can.

Step-by-step explanation:

Possibility of this bring a polyhedron can be proved by Euler's formula, i.e

F+V-E=2

F=10 V=3 E=11

=10+3-11

Essentially, it is 13 - 11, which is 2.

2 = 2, so yes, this does work.

Answer:

Then the count of 1 cent stamps is 15 −x. So for total cost we have. [45x + 1(15 − x)]cents = $4.55. but there are 100 cents in 1 dollar so we change the above to. [45x +1(15 −x)] 100 = 4.55. Multiply both sides by 100. 45x + 15− x = 455. 44x = 440.
