Jim is showing his work in simplifying (−8.5 + 6.1) − 1.3.

dexar [7]

Answer:

In step 4, Jim's answer is incorrect.

Step-by-step explanation:

In step 1, Jim swaps the order of addends using the commutative property of addition.

In step 2, Jim uses the distributive property to factor -1 from the final two terms. (The associative property lets Jim move parentheses.)

6.1 +(-8.5 -1.3) . . . associative property

6.1 +(-1)(8.5 +1.3) . . . distributive property

In step 3, Jim has used the properties of real numbers to form the sum of two of them.

In step 4, Jim wrote an answer of 1.1, when the answer should have been -3.7. Jim's answer is incorrect.

The descriptive statements about steps 2 and 4 are both true.

There are currently 18 pit bulls at the pound. Of the 18 pit bulls, four have attacked another dog in the last year. Joe, a memb

laila [671]

Answer: 0.7748

Step-by-step explanation:

Given : Number of bit bulls at the pound = 18

Number of pit bulls have attacked another dog in the last year =4

The proportion of pit bulls have attacked another dog in the last year: $p=\dfrac{4}{18}\approx0.22$

Number of the pit bulls selected = 6

The probability of that none of the pit bulls in Joe's group attacked another dog last year : $P(0)=(1-0.22)^6=0.225199600704\approx0.2252$

By using binomial , the probability that at least one of the pit bulls in Joe's group attacked another dog last year is given by :-

$P(x\geq 1)=1-P(x$

Hence, the required probability = 0.7748
