Answer:

x = -2 or x = 1/3 thus: B & C

Step-by-step explanation:

Solve for x over the real numbers:

2 x^2 + 7 x - 2 = 2 x - x^2

Subtract 2 x - x^2 from both sides:

3 x^2 + 5 x - 2 = 0

The left hand side factors into a product with two terms:

(x + 2) (3 x - 1) = 0

Split into two equations:

x + 2 = 0 or 3 x - 1 = 0

Subtract 2 from both sides:

x = -2 or 3 x - 1 = 0

Add 1 to both sides:

x = -2 or 3 x = 1

Divide both sides by 3:

Answer: x = -2 or x = 1/3

Fifty percent of households say they would feel secure if they had $50,000 in savings. you randomly select 8 households and ask

Setler [38]

Step-by-step Answer:

"Fifty percent of households say they would feel secure if they had $50,000 in savings." => population mean for satisfaction is 0.50.

N = number of household asked.

x = number of satisfied households.

Use binomial probability,

B(x,N,p) = C(N,x)*(p^x)*(1-p)^(N-x)

For 8 households and 3 questions (a), (b), and (c), we can tabulate all values of x and extract answers from there.

x B(x,8,0.5) cumulative probability

0 0.00390625 0.00390625

1 0.03125 0.03515625

2 0.109375 0.14453125

3 0.21875 0.36328125

4 0.2734375 0.63671875

5 0.21875 0.85546875

6 0.109375 0.96484375

7 0.03125 0.99609375

8 0.00390625 1.0

From the table, we see clearly that

(a) probability P(x=5)=0.2188

(b) probability P(x>5)=1-0.8555=0.1445

(c) probability P(x<=5) = 0.8555

A boat traveled 240 miles downstream, then 240 miles back upstream. The trip downstream took 20 hours. The trip back upstream to

kotykmax [81]

Answer:

it takes longer for the boat to get back because it's moving against the current. to see how fast the boat is moving, you divide the amount of miles traveled, by how long it took.

240/20 = 12

in still water the boat travels it's 12 miles per hour

240/ 60 = 4

against the current, the boat travels 4 miles per hour

if you need to find the speed of the current, you need to find the resistance that's going against the boat making it slow down. you do that by doing 12 - 4 = 8 miles per hour is the speed of the current.

Step-by-step explanation:

I hope this helps :)

A company is worth $79,600,000. Write this number in scientific notation.<br><br> 79,600,000=

Alina [70]

Answer:

The answer is 7.96×10⁷ .

Step-by-step explanation:

As the decimal moves to the <u>l</u><u>e</u><u>f</u><u>t</u> , you have to add one more power to the base 10 :

e.g

7 960 000.0 = 7 960 000×10¹

796 000.00 = 796 000×10²

79 600.000 = 79 600×10³

7 960.0000 = 7 960×10⁴

796.00000 = 796×10⁵

79.600000 = 79.6×10⁶

7.9600000 = 7.96×10⁷

* Take note :

$a \times {10}^{n}$

0 < a < 10 ('a' must be greater than 0 but smaller than 10)
