Answer:
a) kg of plant food did Sheldon have left.
b) She need is kg and she don't have enough to left.
Step-by-step explanation:
Given : On Sunday, Sheldon bought kg of plant food. He used
kg on his strawberry plants and used
kg for his tomato plants.
To find :
a) How many kilograms of plant food did Sheldon have left? Write one or more equations to show how you reached your answer.
Solution :
Sheldon bought plant food kg.
He used strawberry plants kg.
He used tomato plants kg
Kilograms of plant food did Sheldon have left is given by,
Therefore, kg of plant food did Sheldon have left.
b) Sheldon wants to feed his strawberry plants 2 more times and his tomato plants one more time. He will use the same amounts of plant food as before. How much plant food will he need? Does he have enough left to do so?
Solution :
Sheldon wants to feed his strawberry plants 2 more times.
i.e. Strawberry plants used is kg.
His tomato plants one more time i.e. kg.
Total plant she need is
As
No she don't have enough to left.
The exponential regression equation is y = 172.21(0.99)ˣ and at x = 60 minutes y = 94.22 degree Fahrenheit and at x = 240 minutes y = 15.43 degree Fahrenheit.
<h3>What is correlation?</h3>It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have data shown in the table:
We can find the exponential regression equation using the data shown.
After calculating from the data:
a = 172.21 and b = 0.99
The correlation coefficient will be:
r = -0.99
The range will be all real numbers.
The domain will be y > 0
As we can see in the graph x ∈R and y>0
After an hour,
Plug x = 60 minutes in the exponential regression equation:
y = 94.22 degree Fahrenheit
After 4 hours, plug x = 240
y = 15.43 degree Fahrenheit
Similarly, we can find any data from the exponential regression equation.
Thus, the exponential regression equation is y = 172.21(0.99)ˣ and at x = 60 minutes y = 94.22 degree Fahrenheit and at x = 240 minutes y = 15.43 degree Fahrenheit.
