(((x + y) / 3) + (1 / x)) / (5 + (15 / x))
The best way is to make it one fraction.
Multiply by ((3x/3x) / (3x/3x)) to remove the other fractions.
((x(x + y)) + 3(1)) / (5(3x) + 3(15))
(x^2 + xy + 3) / (15x + 45)
Then factor to simplify
(x^2 + xy + 3) / (3(x + 15))

Given:

The expression is

$9-3\div \dfrac{1}{3}+1$

To find:

The value of given expression.

Solution:

We have,

$9-3\div \dfrac{1}{3}+1$

BODMAS : Bracket, Order, Division, Multiplication, Addition, and Subtraction.

Using BODMAS, first we need to perform division in the given expression.

$=9-(3\div \dfrac{1}{3})+1$

$=9-(3\times 3)+1$

$=9-9+1$

Now, apply addition.

$=(9+1)-9$

$=10-9$

Now, apply subtraction.

$=1$

Therefore, the value of given expression is 1.

Does the frequency distribution appear to have a normal distribution? Explain. Temperature (degreesF) Frequency 35 dash 39 1

AlexFokin [52]

Answer:

D. Yes, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric.

Step-by-step explanation:

Hello!

The given frequency distribution for temperatures.

To see if the distribution appears to have a normal distribution you have to draw a histogram using the information. Check attachment.

As you can see, the distribution appears symmetric, it starts low and proceeds to grow until it reaches its maximum point (f(4)=13) and then starts to decrease to low frequencies. The right tail decreases a little more than the left one but it is almost symmetrical.

I hope this helps!

Students are painting a mural. So far the mural is painted 1/4 blue 2/8 red and 3/12 green. Use fraction strips to determine how

nirvana33 [79]

If you make the denominators all the same, the fractions are 3/12 , 3/12 , and 3/12. Then by simply adding them together you get that the mural is 9/12 painted. that then simplifies to 3/4 or 75%

Hope this helps :)
