A coin is tossed times and comes up heads times. Use the Empirical Method to approximate the probability that the coin comes up

heads. Round your answer to four decimal places as necessary.
Mathematics

Answer:

P(head) = 0.5600

Step-by-step explanation:

Given

n = 500 -- number of toss

head = 280 --- outcomes of head

<em>See comment</em>

Required

Empirical probability of head

This is calculated as:

P(head) = \frac{n(head)}{n}

P(head) = \frac{280}{500}

P(head) = 0.5600

Use distributive property to rewrite problem so it had only two factors. Then solve (25x9)+(75x9)=
Shalnov [3]

ANSWER

(25\times9)+(75\times9)=9(25+75)


(25\times9)+(75\times9)=9(100)


(25\times9)+(75\times9)=900


EXPLANATION


According to the distributive property,

(a\times b)+(a\times c)=a(b+c)

This implies that,

(25\times9)+(75\times9)=9(25+75)


(25\times9)+(75\times9)=9(100)

The Right Hand Side of the equation now has 2 factors.


We solve now to obtain;


(25\times9)+(75\times9)=900

Find the slope of the line through<br> (-11,8),(-11, -17)
Rom4ik [11]

Answer:

Undefined or Infinity

Step-by-step explanation:

(x1,y1)=(-11,8)

(x2,y2)=(-11,-17)

Slope = (y2-y1)/(x2-x1)

= (-17-8)/(-11-(-11))

= -25/0

= Undefined

Find the -scores that bound the middle 96 of the area under the standard normal curve by using the TI-84 calculator.
Korvikt [17]

Answer:

\alpha=1-0.96 =0.04

And \alpha/2= 0.02 and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

z_{\alpha/2}= \pm 2.054

Step-by-step explanation:

For this case we want to find the limits with the middle 96% of the area below the normal curve, then the significance level would be:

\alpha=1-0.96 =0.04

And \alpha/2= 0.02 and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

z_{\alpha/2}= \pm 2.054

The table represents the linear function f(x), and the equation represents the linear function g(x).
Eva8 [605]

9514 1404 393

Answer:

  The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).

Step-by-step explanation:

The y-intercept is the function value when x=0. The table shows f(0) = 1. The equation shows g(0) = 1, so the y-intercepts are equal.

__

The value of f(x) changes by (11 -1) = 10 when the value of x changes by (2 -0) = 2. That means the slope of f(x) is 10/2 = 5.

The slope of g(x) is the x-coefficient, 4. We note that 5 > 4, so the slope of f(x) is greater than for g(x).

The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
