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 sides of a triangle are 3 whole 1 by 6 cm 4 whole 2 by 3 cm and 5 whole 2 by 3 cm. Find the total length of the three sides

Lyrx [107]

Answer:

$16\frac{2}{3}$ cm

Step-by-step explanation:

Given dimensions:

$3\frac{1}{6}$ cm by $4\frac{2}{3}$ cm by $5\frac{2}{3}$ cm

The total length:

it is the sum of all the sides;

$\frac{19}{6} + \frac{14}{3} + \frac{17}{3}$

LCM of the denominators = 6 ;

$\frac{38 + 28 + 34}{6}$ = $\frac{100}{6}$

= $\frac{50}{3}$

= $16\frac{2}{3}$ cm

Reptile [31]

Answer:

$\frac{14}{15}$

Step-by-step explanation:

$\frac{4}{5}$ × $\frac{3}{9}$ + $\frac{2}{3}$ ( firstly, multiply the 2 fractions together )

= $\frac{12}{45}$ + $\frac{2}{3}$

= $\frac{4}{15}$ + $\frac{2}{3}$

= $\frac{4}{15}$ + $\frac{2(5)}{3(5)}$

= $\frac{4}{15}$ + $\frac{10}{15}$

= $\frac{14}{15}$
