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

Find the given angle to the nearest degree.

Darina [25.2K]

Answer:

$\alpha=44\°$

Step-by-step explanation:

By definition, the tangent of an angle is the quotient between the side opposite the angle and the side adjacent to the angle

In other words:

$tan(\alpha) = \frac{opposite}{adjacent}$

In this triangle, the length of the side adjacent to the desired angle is 50, and the length of the opposite side is 48

So:

$tan(\alpha) = \frac{48}{50}\\\\tan(\alpha)= 0.96$

Finally

$\alpha =arctan(0.96)\\\\\alpha=44\°$
