Answer:
D.the treatment group (placebo or reading strategies)
Step-by-step explanation:
This cognitive psychologists wants to find out if better reading strategies when taught to students would have any effect on their test scores.
So the dependent variable in this experiment would be the test scores that she wants to find from the test.
While the independent variable would be the treatment group which is the placebo or treatment. The psychologist wants to measure outcomes in this dependent variable using changes in the independent variable (placebo/treatment).
Answer:36π squared feet
Step-by-step explanation:
Diameter=12
Radius=diameter/2
Radius=12/2
Radius=6 feet
Area of circle=π x Radius x Radius
Area of circle=π x 6 x 6
Area of circle=36π
SOLUTION:
Step 1:
In this question, we are given the following:
Step 2:
The details of the solution are as follows:
Step-by-step explanation:
Given :
At the state fair, admission at the gate is $9.
In addition, the cost of each ride is $3.
Suppose that Sam will go on x rides.
Then, cost of x rides ( in dollars) = Cost per ride x Number of rides
=3x
Total cost ( in dollars) : Admission fee + cost of x rides
= 9+3x
Sam wants the total number of dollars he spends on admission and rides to be at most t ( less than or equal to t )
CONCLUSION:
The final answer is:
Using the values and variables given, write an inequality describing this.
a = length of one side.
Area of a square = a^2
in our problem,
Area = 169 square inches
a = ?
Plug our numbers into the area formula mentioned above.
169 in^2 = a^2.
Take the square root of each side to find the side length of the square shaped platter.
13 = a
