To test the effectiveness of a new, cholesterol-lowering drug, a group of researchers recruits 200 volunteers with high cholesterol to take part in a study. The researchers place the numbers 1 through 200 in a hat and have each participant select a number. Those who picked an odd number receive the new drug, while those who picked an even number receive a placebo. Which experimental design are the researchers using?
a. Representative Sample Design
b. Completely Randomized Design
c. Matched-Pair Design
d. Randomized Block Design
Answer:
c. Matched-Pair Design
Step-by-step explanation:
The experimental research study showcased above exhibits two different treatments groups ; the new cholesterol lowering drug and the placebo. The allocation of observations or subjects into groups was based on pair selection which is based on whether subjects picked an even or odd number. Subjects who picked the odd are moved to the treatment group of the new drug while those who picked an even number are referred to the placebo treatment group. This type of research design which involves two pairs of treatment and allotment pattern is called a matched pair research design
Answer:
Completely Randomized Design
Step-by-step explanation:
Rationale: When all patients aer assigned treatment or control randomly without considering other factors, this is called a cmpletely randomized design.

Wilma has 28 coins, all nickels, and dimes worth $2.05. How many nickels does she have?
Answer:
15 nickels and 13 dimes
Step-by-step explanation:
5n + 10d = 205 cents
n + d = 28
n = 28-d
5(28-d) +10d = 205
140 -5d + 10d = 205
5d = 65
d = 13
n = 28-d = 28-13 = 15
5n = 5(15) = 75
10d = 10(13) = 130
75+130=205

A company has recently been hiring new employees. Today the company has 34% more employees than it did a year ago. If there are currently
33,500 employees, how many employees did the company have a year ago?
Answer:
22110 employees.
Step-by-step explanation:
33500 decrease 34% =
33500 × (1 - 34%) = 33500 × (1 - 0.34) = 22110
Answer:
The company had 22,110 employees a year ago.
Step-by-step explanation:
34% of 33,500 is 11,390
33,500 - 11,390 = 22,110

This question is incomplete, the complete question is;
A fair coin is tossed three times and the events AA, BB, and CC are defined as follows: A:{A:{ At least one head is observed }} B:{B:{ At least two heads are observed }} C:{C:{ The number of heads observed is odd }} Find the following probabilities by summing the probabilities of the appropriate sample points (note that 0 is an even number): a) P(B) =, b) P(A or B) =
Answer:
a) probability of B is 0.5
b) probability of (A or B) is 0.875
Step-by-step explanation:
Given the data in the question;
The coin is tossed 3 times.
so let S represent the sample space with the probabilities;
S = [ HHH, HHT, HTH, THH, HTT, THT, TTH, TTT ]
so n(S) = 8
now let A be the set where at least one head is observed;
A = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]
n( A) = 7
let B be the set where at least two head is observed;
B = [ HHH, HHT, HTH, THH, ]
n(B) = 4
let C be the set where number of heads are odd;
C = [ HHH, HTT, THT, TTH ]
n(C) = 4
so
a) P(B) = ?
probability of B will be;
P(B) = n(B) / n(S)
we substitute
P(B) = 4 / 8 = 0.5
Therefore, probability of B is 0.5
b) P(A or B) = ?
the favorable number of cases to event A∪B is
A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]∪[ HHH, HHT, HTH, THH, ]
A∪B = [ HHH, HHT, HTH, THH, HTT, THT, TTH, ]
n(A∪B) = 7
Now the probability of A or B will be
P( A∪B ) = n(A∪B) / n(S) = 7/8 = 0.875
Therefore, probability of (A or B) is 0.875

What are all the factors of 76
Answer:
1, 2, 4, 19, 38, 76
Simplify the expression:
8 ( 5w + 7) + 9 (4w - 7)
Answer:
40
Step-by-step explanation:
Answer: 1.Remove any grouping symbol such as brackets and parentheses by multiplying factors.
2.Use the exponent rule to remove grouping if the terms are containing exponents.
3.Combine the like terms by addition or subtraction.
4. Combine the constants
Step-by-step explanation:
[tex]8(5w+7) + 9 ( 4w- 7)[/tex]
The first thing we do is distribute
[tex]8(5w+7)& 9(4w-7)[/tex]
We distribute what is outside the parenthesis to everything that is inside the parenthesis
so for 8(5w+7) we do [tex]8x5w = 40w[/tex] and [tex]8x7 = 56[/tex]
so for 9 So 9(4w−7) turns into 36w+63
so now we have 40w+56+36w+−63
now combine like terms
(40w+36w)+(56+−63)=?

В.

E
А
D
The length of diagonal BD from the parallelogram ABCD is 10.
The midpoint of diagonals BD and AC is E. Hence, the point of bisection is marked E.
BE = DE (The diagonals of a parallelogram bisect each other)
From the diagram given :
BE = 5
DE = BE = 5
Length of BD = BE + DE
Length of BD = (5 + 5) = 10
Therefore, the length of Diagonal BD is 10.

Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 16 feet, and the ball 2 is dropped from a height of 144 feet. Write and graph a function for the height of each ball. Then use the graphs to tell when each ball will reach the ground.
Answer:
Two identical rubber balls are dropped from different heights. Ball 1 is dropped from a height of 181 feet, and ball 2 is dropped from a height of 238 feet. Write a function for the height of each ball.
h1(t) = -16t^2 + 181
h2(t) = -16t^2 + 238
When does ball 1 reach the ground? Round to the nearest hundredth. seconds
Solve: -16t^2+181 = 0
-16t^2 = -181
t^2 = 11.3125
t = 3.3634 seconds
