Jamie says the value of the expression 1.43 × (−

irinina [24]

Jamie's estimate is reasonable.

Explanation:

The expression is $1.43 \times\left(-\frac{16}{31}\right)$

Dividing the term $\left(-\frac{16}{31}\right)$ , we get,

$1.43 \times(-0.51613)$

Multiplying the terms, we have,

$-0.7380659$

But, Jamie's estimate is $-0.75$

The difference between the two values is $0.0119341$ which is negligible.

Hence, Jamie's estimate is reasonable.

A dice game lets you roll 2 6 sided disc and find the sum of the numbers. A 12 wins 100 dollars, 10 or 11 wins 50 dollars, a 2 w

Advocard [28]

Answer:

Step-by-step explanation:

A two 6 sided die is rolled

Sample space would be (1,1)...(1,6)....(6,1)....(6,6)

Let x be the sum obtained

X can take values as 2 or 3 ....12

P(x=12) = P(6,6) =1/36

P(x=10 or 11) = P{(5,5)(5,6) (6,5) (4,6)(6,4)}=5/36

P(2) =P(1,1) = 1/36

For other outcomes no payment

Thus we can list this as

Sum 2 3 4 5 6 7 8 9 10 or 11 12

Prob 1/36 5/36 1/36

Gain 3 0 0 0 0 0 0 0 50 100

E(gain) 3/36 0 0 0 0 0 0 0 250/36 100/36

E(gain) = total= 353/36

Cost of game = 6

E(outcome) = E(gain -6) = E(gain)-6 = 353/36 -6

= 3.806

How do you solve z/-4<2

ohaa [14]

Z / -4 < 2....multiply both sides by -4, cancelling out the -4 on the left. And dont forget to change the inequality sign because of multiplying by a negative.

z > 2 * -4
z > -8
