Translate the word problem into an equation and solve algebraically. Include correct units. The length of a
rectangular area is 4 feet more than its width. If the area is 45 square feet, find the length and the width of the
rectangle.
Answers
Step-by-step explanation: TS 5 15 8 26
L = W + 4
Area = 45 ft²
Area = LW
Area = (W +4)(W) = 45 ft²
W² + 4W - 45 = 0 solve for W
(W + 9)(W - 5) = 0
W = -9 or 5 a minus 9 width makes no sense
L = W + 4
L = 5 + 4
W = 5 ft L = 9 ft

From a standard deck of cards, your first draw is a black card. You replace the card, and the second draw is a diamond. Which THREE statements are correct for the outcome of the event? A) The probability of drawing the black card is 1/2 B) The probability of drawing the diamond is 1/4 C)The probability of the compound event is 1/6 D) The probability of the compound event is 1/8 E) The probability of the compound event is 3/4
Answers
A: because there are two colour types in a deck of cards, so it’s 1/2 probability of getting a black one.
B: because there a four suits in a deck of cards, so the probability of getting a diamond is 1/4
D: because when calculating compound events we multiply the two probabilities,
so 1/2 x 1/4 = 1/8
For each of the following research scenarios, decide whether the design uses a related sample. If the design uses a related sample, identify whether it uses matched subjects or repeated measures. (Note: Researchers can match subjects by matching particular characteristics, or, in some cases, matched subjects are naturally paired, such as siblings or married couples).
A researcher is interested in whether people eat more or less when they are in a hurry. The researcher collects a random sample of 80 adults and invites them to eat two (identical) free meals one month apart. For one of the meals, no time restriction is placed on the meal. For the other meal, participants are told when their meal is served that they have only 10 minutes until another group is due to sit down. Half of the participants eat their hurried meal first; the other half eat it second. The researcher compares the amount eaten at each sitting. The design described_____.
John Cacioppo was interested in possible mechanisms by which loneliness may have deleterious effects on health. He compared the sleep quality of a random sample of lonely people to the sleep quality of a random sample of nonlonely people. The design described____.
a. uses a related sample (repeated measures).
b. uses a related sample (matched subjects).
c. does not use a related sample.
Answers
Answer:
A.) uses a related sample (repeated measures).
B.) does not use a related sample.
Step-by-step explanation:
The first scenario uses a related sample whereby same subjects were used to over the course of each related experiment (comparing if people eat more or less when in a hurry). After the completion of both experiment, we'll have two different reading for each subject which a b further be used to compare the difference in consumption when in a hurry and when not.
The second scenario here fails to employ a related sample design as the the subjects used have contrasting characteristics, a group consisting of lonely people and another consisting of those who aren't lonely.

Answer:
Mathematics :Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports.
Since the beginning of recorded history, mathematic discovery has been at the forefront of every civilized society, and in use in even the most primitive of cultures. The needs of math arose based on the wants of society. The more complex a society, the more complex the mathematical needs. Primitive tribes needed little more than the ability to count, but also relied on math to calculate the position of the sun and the physics of hunting.

[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]
= [tex]15^{2}[/tex] = [tex]8^{2}[/tex]
= 225 + 64

A rectangle has an area of 99 square in. What is the length of the long side?
Answers
Answer:
The longer length is either 99, 33 or 11 inches
Step-by-step explanation:
Given
[tex]Area = 99[/tex]
Required
The length of the longer side
Area of a rectangle is:
[tex]Area = Length * Width[/tex]
List out all possible products that give 99 [Assume the dimension are whole numbers]
[tex]Length * Width = 99 * 1 = 99[/tex]
[tex]Length * Width = 33 * 3 = 99[/tex]
[tex]Length * Width = 11 * 9 = 99[/tex]
List out the longer factors
[tex]L = \{99, 33, 11\}[/tex]
Hence, the longer length is either 99, 33 or 11 inches
What is the value of the expression f(-3) + 2f(-1) - f (4)
PLEASE HELP NO LINKS
Answers
Answer:
22
Step-by-step explanation:
Find f(-3) :
f(x) = x² + 2x for x ≤ -3
That means for those values of x, less than or equal to -3, this is the function.
So, f(-3) = (-3)² + 2(-3) = 9 - 6 = 3
Now, f(-1) :
From the given data, we see it is: f(x) = 2 [tex](\frac{1}{3} )^{2x}[/tex]
We take this because -1 lies between -3 and 4.
Now, f(-1) = 2 [tex](\frac{1}{3} )^{2(-1)}[/tex]
=> [tex]f = (-1) = 2(3)^{2} = 2 (9) = 18[/tex]
For f(4) :
Clearly, the function is: [tex]f (x) = \frac{2x - 5}{x-7}[/tex]
[tex]f (4) = \frac{2(4)-5}{4-7} = \frac{3}{-3} = -1[/tex]
Therefore, f(-3) + f(-1) - f(4) = 3 + 18 - (-1) = 3 + 18 + 1 = 22.

Reformatting the input :
Changes made to your input should not affect the solution:

STEP1
Equation at the end of step 1
(6x + 3) • ((3x2 + 8x) + 5)
STEP2
STEP3
Pulling out like terms
3.1 Pull out like factors :
6x + 3 = 3 • (2x + 1)
Trying to factor by splitting the middle term
3.2 Factoring 3x2 + 8x + 5
The first term is, 3x2 its coefficient is 3 .
The middle term is, +8x its coefficient is 8 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 3 • 5 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5
3x2 + 3x + 5x + 5
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x+1)
Add up the last 2 terms, pulling out common factors :
5 • (x+1)
Step-5 : Add up the four terms of step 4 :
(3x+5) • (x+1)

250 grams of sugar cost 150 dollars at Shop X. 100 grams of sugar cost 95 dollars at Shop Y. What is the difference in cost per kilogramme?
Answers
350 dollars
Step-by-step explanation:(step 1) Find the cost per kilogramme of sugar in shop X
In shop X:
250 grams of sugar costs 150 dollars.
Remember that;
1000 grams = 1 kilogramme.
=> 250 grams will be equal to 0.25 kilogramme
Therefore (replacing 250 grams with 0.25 kilogramme) in shop X;
0.25 kilogramme of sugar costs 150 dollars
Now, if
0.25 kilogramme = 150 dollars,
=> 1 kilogramme = 150 dollars x 1 kilogramme / 0.25 kilogramme
=> 1 kilogramme = 600 dollars
Therefore, the cost per kilogramme of sugar in shop X is 600 dollars
(step 2) Find the cost per kilogramme of sugar in shop Y
In shop Y:
100 grams of sugar costs 95 dollars.
Remember that;
1000 grams = 1 kilogramme.
=> 100 grams will be equal to 0.1 kilogramme
Therefore (replacing 100 grams with 0.1 kilogramme) in shop Y;
0.1 kilogramme of sugar costs 95 dollars
Now, if
0.1 kilogramme = 95 dollars,
=> 1 kilogramme = 95 dollars x 1 kilogramme / 0.1 kilogramme
=> 1 kilogramme = 950 dollars
Therefore, the cost per kilogramme of sugar in shop Y is 950 dollars
(step 3) Find the difference in cost per kilogramme of sugar between the two shops
The difference is calculated by subtracting the cost per kilogramme of sugar in shop X from the cost per kilogramme of sugar in shop Y. i.e
=> cost per kilogramme of sugar in shop Y - cost per kilogramme of sugar in shop X
=> 950 dollars - 600 dollars
=> 350 dollars.
Therefore, the difference in cost per kilogramme is 350 dollars

Answer:
54 = 2 × 3³
36 = 2² × 3²
Step-by-step explanation:
The term "factors" can mean different things in this context. Usually, it means "prime factors." Exponents are used to indicate the number of times a factor is repeated. The prime factors of these numbers are ...
54 = 2 × 3³
36 = 2² × 3²
__
Sometimes, we use the word "factors" to mean "positive integer divisors." The number of divisors is the product of the exponents of the prime factors, each increased by 1. That is, 54 has (2·4) = 8 divisors; 36 has (3·3) = 9 divisors. The odd number of divisors is one indication that the number is a perfect square.
The divisors of these numbers are ...
54 is divisible by 1, 2, 3, 6, 9, 18, 27, 54
36 is divisible by 1, 2, 3, 4, 6, 9, 12, 18, 36
