Answer:

Exact Form: -53/12

decimal form: -4.416

mixed number -4 5/12

Step-by-step explanation:

convert mixed numbers into improper fractions: -2 3/3 +(5 1/2)+ 8 3/4

convert mixed numbers into improper fractions: =11/2  =-\frac{23}{3}+\left(-\frac{11}{2}\right)+\frac{35}{4} =

-\frac{23}{3}+\left-\frac{11}{2}\right+\frac{35}{4}=-\frac{92}{12}-\frac{66}{12}+\frac{105}{12}

\frac{-92-66+105}{12}

add/subtract the numbers: -92-66+105=-53

-53/12

apply the fraction rule: \frac{-a}{b} = -\frac{a}{b\\}

=-\frac{53}{12}\\

A chocolate manufacturing company produces two types of chocolate: A and B. Ingredients required for manufacturing the products
Karolina [17]

Answer:

The maximum profit is when they make 10 units of A and 2 units of B.

Step-by-step explanation:

Let x is units of milk

Let y units of cacao

Given that :

The company's production plant has a total of 22 units of milk and 46 units of cacao available.

2x + y ≤ 22 (2 unit of milk for each of A and 1 for B; 22 units available)

4x + 3y ≤46 (4 unit of milk for each of A and 3 for B; 46 units available

Graph the constraint equations and find the point of intersection to determine the feasibility region.

The intersection point (algebraically, or from the graph) is (10, 2)

The objective function for the problem is the total profit, which is $6.2 per unit for A and $4.2 per unit for B: 6.2x + 4.2y.

Hence, we substitute (10, 2)  into the above function:

6.2*10 + 4.2*2 = 70.4

The maximum profit is when they make 10 units of A and 2 units of B.

fiasKO [112]

Answer:

The probability that the next person asked has two pets is 0.176

Step-by-step explanation:

The given parameters are;

The frequency distribution of the number of pets owned is presented as follows;

Number of Times    {}    Frequency  {}      

None                          {}   354

One                          {}     981

Two                          {}     352

Three                          {}  200

Four                           {}    113

The probability that the next person asked has two pets = Proportion of the sample that own two pets = 352/(354 + 981 + 352 + 200 + 113) = 0.176

Therefore, the probability that the next person asked has two pets = 0.176
