You buy a lottery ticket to a lottery that costs $10 per ticket. There are only 100 tickets available to be sold in this lottery

Marat540 [252]

There is a profit of $39.7.

It is given that there 100 tickets costing $10 per ticket.

You must look first for the probability of the 4 prizes which are $475, $195, $30, and no prize.

P ($475 prize) = 1/100 or 0.01

P ($95 prize) = 2/100 or 0.02

P ($30 prize) = 4/100 or 0.04

P (No prize) = 100/100 – 1+2+4/100 =93/100 .93

Expected gain or loss is computed by: (P(x)* n)

E= (475-10)*.01 + (95-10)*0.02 + (30-10)* 0.04 + (-10)*.93

= 46.5 + 1.70 + 0.8 – 9.3

E = 39.7

There is a profit of $39.7.

The following situation calls for a significance test. State the appropriate null hypothesis <img src="https://tex.z-dn.net/?f=H

harina [27]

Answer:

$H_{0}: \sigma = 10\\$

$H_{a}: \sigma > 10\\$

Step-by-step explanation:

We are given the following in the question:

The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.

This will be stated by the null hypothesis.

$H_{0}: \sigma = 10\\$

It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.

This will be stated by the alternate hypothesis.

$H_{a}: \sigma > 10\\$

The parameter for the given hypothesis is standard deviation, $\sigma$ .

-n/2 - 4 + 9f Variables n = 6 f = 4

mr_godi [17]

Step-by-step explanation:

what do we need to do ?

just calculate the value of the expression with these values for the variables ?

what's the problem ? this is basic calculating :

-6/2 - 4 + 9×4 = -3 - 4 + 36 = 29

remember (please, for your life !) that multiplication and division always have to be calculated before additions and subtractions (except when brackets force is to go a different route).
