Answer 1

Answer:

Answer:

Step-by-step explanation:

5) 6 : 18 = $(6*1)/(6*3) = 1 : 3$

6) $10 : 12 = (2*5)/(2*6) = (5)/(6)= 5 : 6$

7) $12 : 28 =(4*3)/(4*7)=(3)/(7)= 3:7$

$8) 18:24 =(6*3)/(6*4)=(3)/(4) = 3 : 4\n\n\n9)16 : 20 =(4*4)/(4*5)=(4)/(5)=4:5\n\n\n10) 15:9=(5*3)/(3*3)=(5)/(3)=5:3\n\n\n11)5:30 =(5*1)/(5*6)=(1)/(6)=1:6\n\n\n12)14:10=(2*7)/(2*5)=(7)/(5)=7:5\n\n\n13)6:16=(2*3)/(2*8)=(3)/(8)=3:8\n\n\n14)20:35=(5*4)/(5*7)=(4)/(7)=4:7\n\n$

To reduce to simplest form, find Greatest Common Factor of the two numbers and divide both numbers by the GCF

21 = 3 * 7

9 = 3 * 3

GCF = 3

$(21)/(9)=(3*7)/(3*3)=(7)/(3)=7:3$

Answer 2

Answer:

Answer:

Step-by-step explanation:

5) 6:18 = 1:3

6) 10:12 = 5:6

7) 12:28 = 6:14 = 3:7

8) 18:24 = 6:8 = 3:4

9) 16:20 = 8:10 = 4:5

10) 15:9 = 5:3

11) 5:30 = 1:6

12) 14:10 = 7:5

13) 6:16 = 3:8

14) 20:35 = 4:7

Hope this helps

Answer:

13/4

Step-by-step explanation:

A large pharmaceutical company is trying to determine whether a drug aptly named Recall-Pro can increase your short-term memory capacity. The company prepares a double-blind study as follows:Step 1: A randomly selected pool of individuals is brought to a clinic and is evaluated for any existing health conditions that may impair the results of this experiment.

Step 2: The remaining individuals are split into two groups: a treatment group and a control group.

Step 3: The control group receives a placebo, but neither the researcher nor the individuals know this.

Step 4: The treatment group receives Recall-Pro, but neither the researcher nor the individuals know this.

Which step is flawed in the double-blind study? Why?
A.Step 1; health screening should not eliminate participants from the study
B.Step 2; it does not specify whether the two groups are chosen randomly
C.Step 3; the control group does not receive the placebo
D.Step 4; members of the treatment group should know that they have received the medication

Answers

The best answer to the question that is being stated above would be letter B. Step 2 is the one that is flawed in the double-blind study because it does not specify that the two groups were randomly chosen. It is important to assign the participants randomly so that the results give a non-confounded result.

F(x)=3x+1 and g(x)=x^2-6 find (f+g)(x)

Answers

Answer is x^2 + 3x - 5 As, f(x) = 3x + 1 And g(x) = x^2 - 6 We have to find (f+g)(x) For that we should know (f+g)(x) = f(x) + g(x) So it will become = (3x + 1) + (x^2 - 6) = 3x + 1 + x^2 - 6 = x^2 + 3x - 5

Answer:

It would be x^2 + 3x - 5.

A city is adding a brick border around the community garden. The garden has the dimensions of x ft by x ft. The dimension of the brick border are x + 12 ft by x + 12 ft. What is the area of the brick border

Answers

Answer:

The area of the brick border is $(24x+144)\ ft^(2)$

Step-by-step explanation:

we know that

The area of the brick border is equal to

$A=(x+12)(x+12)-(x)(x)\n \nA=(x+12)^(2) -x^(2)\n \nA=x^(2)+24x+144-x^(2)\n \nA=(24x+144)\ ft^(2)$
