HELP
Answer: x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
3(x+2)=4(x+1)
Step 1: Simplify both sides of the equation.
3(x+2)=4(x+1)
(3)(x)+(3)(2)=(4)(x)+(4)(1)(Distribute)
3x+6=4x+4
Step 2: Subtract 4x from both sides.
3x+6−4x=4x+4−4x
−x+6=4
Step 3: Subtract 6 from both sides.
−x+6−6=4−6
−x=−2
Step 4: Divide both sides by -1.
−x −1 = −2 −1

About 9% of the population of a large country is hopelessly romantic. If two people are randomly selected, what is the probability both are hopelessly romantic? What is the probability that at least one is hopelessly romantic?
A) The probability that both will be hopelessly romantic is _________. (Round 4 decimal places as needed).
B) The probability that at least one person is hopelessly romantic is _______.
Answer:
A. 0.0081
B. 0.1638
Step-by-step explanation:
From the question, we are told that 9% of the population are hopelessly romantic.
The percentage that are not hopelessly romantic = 100-9 = 91%
The probability of choosing a hopelessly romantic person = 9% = 9/100 = 0.09
The probability of choosing a person who is not hopelessly romantic = 91% = 91/100 = 0.91
Now, we want to select two people and calculate the following probability;
1. Both will be hopelessly romantic
Let’s have the people as A and B
The probability that both will be hopelessly romantic will the the product of being hopelessly romantic probability = 0.09 * 0.09 = 0.0081
b. Probability that at least one person is hopelessly romantic
What this means is that the probability that one of the two ONLY is hopelessly romantic;
We can have two cases here;
Probability (That A is hopelessly while B is not )or Probability (A is not and B is hopeless )
Thus we have :
(0.09 * 0.91) + (0.91 * 0.09) = 0.0819 * 2 = 0.1638

Answer:
80.4
Step-by-step explanation:
You have to first find the area of the circle which the formula for that is pi r^2. So you would set it up as 3.14 (2.5)^2 which you then would solve and get 19.625. Then, you find the area of the square which is length times width. So then you would multiply 10 and 10 and get 100. You then subtract 100 and 19.625 which gives you 80.375 but since it says round to the nearest tenth you'd get 80.4.
Step-by-step explanation:
For no.1
sloution,
for small
[tex]r = 2.5[/tex]
[tex]\pi = 3.14[/tex]
Area(A1)=?
now,
A = π r²
A=3.14*2.5^2
A=19.6
A1=19.6cm^2
For,big square
L=10cm
A2=?
now,
A=L^2
A=10^2
A=100
A2=100cm^2
For shaded area
A=A2-A1
A=100-19.6
A=80.4cm^2
A researcher has recruited 20 volunteers to participate in a study. The researcher wishes to measure the effect of alcohol on an individual's reaction time. The 20 volunteers are randomly divided into two groups. Group 1 will serve as a control group in which participants drink four 1-ounce cups of a liquied that looks, smells, and tastes like alcohol in 15-minute increments. Group 2 will serve as an experimental group in which participants drink four 1-ounce cups of 80-proof alcohol in 15-minute increments. After drinking the last 1-ounce cup, the participants sit for 20 minutes. After the rest period, the reaction time to a stimulus is measured. This is an example of
Answer: Experimental Research
Step-by-step explanation: Experimental Research is the "classical" method of conducting an experiment to a scientific approach. It is the most rigorous of all research designs. In it, an independent variable is used to determine its influence on a dependable variable. Experimental research's unique quality is that it can link cause and effect through between variables.
This method works better at independent variables which can be manipulated or controled and can be conducted in laboratories or field settings.
There are 3 types of experimental research:
Pre-experimental Research Design: it is the simplest and pratical form. In it, a group or groups are observed by the application of the independent variable and determine the change;Quasi-Experimental Research Design: the participants are not randonly selected, there is a control group and independent variable is manipulated;True Experimental Research Design: it is the most accurate of the types. It uses control group, randomized group of participants, statistical analysis to reject or accept a hypothesis. It is the epitome of the experimental research;Experimental Research is important because it gives the opportunity to test
the hypothesis and developing a solid conclusion.

Answer:
but
Step-by-step explanation:
yrge sksue dnd djd d d. r e g g h a s. v j u r d. d c g y t
Tyler's claim about finishing his painting first is False because it will take Benito 10 minutes while Tyler will require over 11 minutes to finish up his painting despite starting before Benito.
Size of fence = 150 feet
Benito's rate = 15 ft/min
Tyler's rate = 11 ft/ min
Size already painted by Tyler when Benito started = 39/2 = 19.5 ft
Portion of fence left for Tyler to paint when Benito started = (150 - 19.5) = 130.5 feets
Time required for Tyler to finish :
Time required = 130.5 ÷ 11 = 11.863 minutes
Time required for Benito to finish :
Time required = 150 ÷ 15 = 10 minutes
Time required for Benito to complete his painting is lesser than Tyler's (10 < 11.863)
Hence, Tyler's claim is False

The length of a rectangle is four times its width. If the perimeter of the rectangle is 90 cm, find its area
Answer:
324
Step-by-step explanation:
L = 4W
P = 2L + 2W = 90
---
2L + 2W = 90
2(4W) + 2W = 90
8W + 2W = 90
10W = 90

W = 9
L = 36

A = 324

Answer:
The area of the rectangle is 324 square centimeter.
Step-by-step explanation:
What is area?
The area is the amount of space within the perimeter of a 2D shape.
What is rectangle?
A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
What is perimeter?
Perimeter is the distance around the edge of a shape.
Let the width of the rectangle be x cm.
Then, the length of the rectangle = 4xcm
Perimeter = 2(length + breadth )
90 = 2(4x+x)
90 = 2*5x
90 = 10x
x = 90/10= 9cm
Width = 9cm
Length = 4*9 = 36 cm
Area = Length*Breadth
=9*36
=324 square centimeter.
