Answer:
50 people
Step-by-step explanation:
-An experimental unit is any physical entity or person or animal that can be randomly assgned to a treatment.
-Such a unit is usually referred to as a unit of statistical analysis.
-Both control and actual experimental units are units of statistical analysis despite receiving different treatments.
-Hence, the experimental units of the study is 50 people.
D. The y-intercept of the function is (0, 5) and e. The function crosses the x-axis twice are true
Answer: x = 22
Explanation:
1) Corresponding sides and correspoding angles of congruent triangles are equal.
2) When you name two congruent triangles the order of the vertices signal which sides and angles are congruents.
That triangle ABC is congruent to triangle DEF means that these are the corresponding parts, which are congruent to each other:
- ∠A and ∠D are congruent
- ∠B and ∠ E are congruent
- ∠C and ∠F are congruent
- Segment AB and segment DE are congruent
- Segment BC and segment EF are congruent
- Segment AC and segment DF are congruent
In the figures, it is given that the segment DF measures (1/2)x - 1 and the corresponding segment AC measures 10 units.
Hence, you set this equation: (1/2)x - 1 = 10
Solving for x:
- (1/2)x = 10 + 1
- (1/2)x = 11
- x = 2(11)
- x = 22 ← answer
I'm working on the same thing down load the algebra tiger it really helps a lot I promise I use it daily to help with these
Answer:

Step-by-step explanation:
We need to find the solution to the following system of equations:
and 
By plugging the value of 'y' into the first equation we have that:
⇒ 
Solving for 'x' we have:

So, the solution to the system of equation is: (37.5, -30)
