The statement about the given table above is true is that Rhonda should use both of these samples as they are to make inferences about the average population of each type of duck in the pond. The answer is letter C. Because both ponds are located far away form each other and the gathered sample is enough to explain the population of the different kinds of birds present.

When Irving was done, he checked his account balance and found he had a total of $95.06. How much money was in Irving’s account
cupoosta [38]
This question is incomplete. The first part of the question says that Irving went shopping and he bought novel, shirt, lunch and potted plant for $8.75, $21.66, $9.13 and $16.89 respectively. After this, he had $95.06 in his account.
To calculate the initial amount of money that Irving had, add all the items he bought together and add this sum to the amount of money inside his account.
Amount of items bought = 8.75 + 21.66 +9.13 + 16.89 = $56. 43
$56.42 + $95.06 = $151.49.
Thus, the correct option is B.

Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles until he reaches a total of 26 m
sergejj [24]

Answer:

1.5x+12=26

Step-by-step explanation:  

Let x be the number of weeks that it will take Andy to reach his goal.

We have been given that Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

1.5x+12=26

Therefore, the equation 1.5x+12=26 can be used to determine x, the number of weeks that it will take Andy to reach his goal.
