D is the answer because 1/3 equals to 2/6 and 1/2 equals to 3/6 so 5/6 plus 2/6 equals to 1 1/6 plus 3/6 equals to 1 4/6 and add 4 plus 3 plus 2 equals to 9 add the one which is 10 and 4/6 simplified is 2/3 so your answer is 10 2/3 or d

Gigi earned $65 for 5 hours of gardening. She earned $90 for 9 hours of office work. Which statement correctly compares Gigi’s e

SIZIF [17.4K]

Hello There!

First we have to see how much does Gigi earns per hour.

For gardening, we are going to divide.

65 ÷ 5 ≈ 13

Gigi earns $13 for gardening for only 1 hour.

Second, we have to see how much Gigi earns per hour for office work.

We will divide

90 ÷ 9 ≈ 10

Now, we can see that Gigi earned $3 more per hour for gardening than for office work.

What is the probability of drawing yellow marble followed by a red marble from a bag containing 12 yellow marbles, 16 red marble

boyakko [2]

Option B

Probability of drawing yellow marble followed by a red marble is $\frac{32}{301}$

Solution:

Given that a bag containing 12 yellow marbles, 16 red marbles, and 15 green marbles

So total number of marbles = 12 + 16 + 15 = 43

To find: probability of drawing yellow marble followed by a red marble if the first marble is not replaced

The probability of an event is given as:

$probability =\frac{\text { number of favorable outcomes }}{\text { total number of possible outcomes }}$$

probability of drawing yellow marble followed by a red marble if the first marble is not replaced:

First we pick up yellow marble.

Number of favorable outcomes = 12 yellow marbles

Total number of possible outcomes = 43 marbles

$\text{ probability} = \frac{12}{43}$

Now we have to pick red marble

But first marble is not replaced

So we have 43 - 1 = 42 number of possible outcomes

Favorable outcomes = 16 red marbles

$\text{ probability} = \frac{16}{42}$

So probability of drawing yellow marble followed by a red marble is:

$\text[ probability } = \frac{12}{43} \times \frac{16}{42} = \frac{32}{301}$

Thus probability of drawing yellow marble followed by a red marble is $\frac{32}{301}$

A snack food manufacturer buys corn for tortilla chips from two cooperatives, one in Iowa and one in Illinois. The price per uni

aleksandrvk [35]

Answer:

a. x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Min 6x1 + 5.5x2

c. x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000

Step-by-step explanation:

a. We can consider the variables x1 and x2 as:

x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Price per unit of Iowa corn = $6

Price per unit of Illinois corn = $5.5

Objective function that would minimize the total cost can be written as:

Min 6x1 + 5.5x2

c. The manufacturer needs at least 12000 units of corn which means that the combined number of units from Iowa and Illinois must be greater than or equal to 12000. So, we can write:

x1 + x2 ≥ 12000

The Iowa cooperative can supply up to 8000 units which means that the value of x1 must not be greater than 8000. So, we can write:

x1 ≤ 8000

Similarly, the Illinois cooperative can supply at least 6000 units which means that the value of x2 must not be less than 6000. So, we can write:

x2 ≥ 6000.

The constraints for these conditions are:

x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000

Gekata [30.6K]

Based on the given scenario above regarding Kevin's scatterplot on the weight of the fishes he caught, the presentation would appear that the points in the scatterplot would go up from left to right because as the weight in pounds rises, so as the weight in kilograms as well. The answer is option A.
