Kelly tells you that when variables are in the denominator, the equation one over two plus three over x equals three over four b

Lera25 [3.4K]

1/2 + 3/x = 3/4
3/x = 3/4 - 1/2
3/x = 3/4 - 2/4
3/x = 1/4....this is a proportion, so we cross multiply
(1)(x) = (3)(4)
x = 12

check..
1/2 + 3/12 = 3/4
6/12 + 3/12 = 3/4
9/12 = 3/4
3/4 = 3/4 (correct)

so x = 12

in a right triangle the length of a hypotenuse is c and the length of one leg is a, and the length of the other leg is b what is

puteri [66]

Answer:

Step-by-step explanation:

a=12 (height)

c=13 (hypotenous)

b=? (base)

By using Pythagoras theorm

We have, hypotenous sq=base sq+height sq

Let b =base SO, base sq=hypotenous Sq-height Sq

=>base Sq =13sq-12sq

Base Sq =169-144

Base Sq =25

Base =5 (shifting the sq)....

(12x + 3) + (-7x+ 5)

mash [69]

Answer:

5x+8

Step-by-step explanation:

We have to distribute the + into -7x+5. So the equation will now be 12x+3-7x+5. Now let's organize it into terms. 12x-7x+3+5. Now let's simplify this. The final answer is 5x+8. That is the final answer!

Hope this helped!!! :D

A state senator believes that 25% of all senators on the finance committee will strongly support the tax proposal she wishes to

sp2606 [1]

$P(X=x)= nC_xp^x(1-p)^{n-x}$ Number of Senators be n=5
Probability that the Senators will strongly support the tax proposal be $p=\frac{25}{100}=0.25$
Let X be the number of Senators will strongly support the tax proposal.
Using Binomial Distribution,
$P(X=x)=nC_xP^x(1-p)^{n-x}$
Now Plug in the values of n and p,
$P(X=x)=nC_xp^x(1-)^{n-x} [\tex] To find the probability that 3 out of the 5 Senators will support the tax proposal is [tex] P(X= 3)=5C_3(0.25)^3(1-0.25)^{5-3}\\ =0.08789$
