For the intercepts you set alternately x=0 and y=0 in your function:

On the X-axis y=0

So

x2y−x2+4y=0

becomes

x2(0)−x2+4(0)=0

→−x2=0

→x=0

On the Y-axis x=0

and the original equation

x2y−x2+4y=0

becomes

(0)2y−(0)2+4y=0

→y=0

The only intercept for the given equation occurs at (0,0)

The national average SAT score is 1028. The standard deviation is 92. What is the 78th percentile score?

OverLord2011 [107]

You're looking for the score $k$ such that

$\mathbb P(X\le k)=0.78$

First transform $X$ to the standard normal random variable.

$\mathbb P(X\le k)=\mathbb P\left(\dfrac{X-1028}{92}\le\dfrac{k-1028}{92}\right)=\mathbb P(Z\le \hat k)=0.78$

Now 0.78 corresponds to a z-score of approximately $\hat k=0.7722$ , which means

$\dfrac{k-1028}{92}=\hat k\implies k\approx92(0.7722)+1028=1099.04\approx1099$

laila [671]

2x^2+7x-4=0
Δ=7^2-4*2*(-4)
Δ=49+32
Δ=81
x1=(-7+V81)/4=(-7+9)/4=2/4=1/2
x2=(-7-9)/4=-16/4=-4

the solutions: x1= 1/2 and x2= - 4

Richard design a great new hotel is hotel is tallest in the city it has 58 floors each floor has 18 room each room has two TV ho

nekit [7.7K]

There are 2088 TVs in his whole hotel.

Step-by-step explanation:

No. of floors = 58

No. of rooms = 18 per floor

Total rooms = No. of floors * No. of rooms per floor

$Total\ rooms = 58*18\\Total\ rooms=1044$

As every room has two TVs, therefore,

Total TVs = Total rooms * 2

$Total\ TVs=1044*2\\Total\ TVs=2088$

There are 2088 TVs in his whole hotel.
