ANSWER:
The correct answer is
-This study is blind.
-This study is an experimental study.
STEP-BY-STEP EXPLANATION:
This study includes a controlled treatment (in this manner it is an investigation) and subjects didn't have a clue about the idea of the treatment so it is visually impaired.
Answer:
Step-by-step explanation:
Work can be found by multiplying the force by the distance traveled in the direction of the force.
The force is 45 Newtons.
The distance traveled is 1 meter.
Substitute the values into the formula.
Multiply.
1 Newton meter is equal to 1 Joules.
Therefore our answer of 45 Newton meters is equal to 45 Joules.
The work done is <u>45 Joules.</u>
Answer:
16/25 = 0.64
Step-by-step explanation:
18 rolls are ones, so 32 rolls are not ones.
The experimental probability is 32/50 = 16/25 = 0.64.
Answer:
see below
Step-by-step explanation:
y= 1/2x - 2
To find the x intercept, set y =0 and solve for x
0= 1/2x - 2
Add 2 to each side
2 = 1/2x -2+2
2 = 1/2x
Multiply by 2
2*2 = 1/2x *2
4 =x
The x intercept is 4
