The cost of 3 diaries is £12
Work out the cost of 7 diaries.
Your final answer must say, 7 diaries cost £
Answer: 28
the cost of 7 diaries is 28
Step-by-step explanation:
First you have to find out the cost of one diary by dividing 12 by 3, that will give us 4, and then the last step is multiplying 4 by 7.
Answer:
7 diaries cost £28

Exercise 1.6 introduces a study on the relationship between socio-economic class and unethical behavior. As part of this study 129 University of (California Berkeley undergraduates were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. After completing some unrelated tasks, participants reported the number of candies they had taken. It was found that those who were identified as upper-class took more candy than others.
A. Identify the population of interest and the sample in this study.
B. Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
(A) Population: UCB undergraduates
Sample: The selected 129 UCB undergraduates
(B) Yes, they can be generalized to the population
No, the findings of this single study cannot be used to establish causal relationships between socio-economic classes and unethical behaviors.
Step-by-step explanation:
STUDY: Relationship between socio-economic class and unethical behavior.
The bases for determining social class here are: money, education, and respected job.
RESULT: Those who identified as upper class took more candy than others.
(A) Identify the population of interest and the sample, in this study.
The population of interest in this study is UCB undergraduates.
The sample in this study is the 129 UCB undergraduates who were selected and who agreed to take part in the experiment. They were the participants who were divided into the two social classes before the experiment was conducted.
(B) The results of the study can be generalized to the population of UCB undergraduates since it's likely that the results would be same in another group of 129 UCB undergraduates.
The findings or results of the study cannot be used to establish causal relationships unless the study is conducted in more universities and majority of the results are same with this.

A central angle of circle P is angle
The measure of RU is degrees.
Answer:
Step-by-step explanation:
RU=59 degrees
angle = TPQ
Central angle of circle P is a angle equals to 121° and 73°.
The measure of arc RU is 59 degrees
What is circle?" A circle is closed two dimensional shape , whose all points on the surface are equidistant from its center."
Definition of arc measure
"In a circle, the degree measure of an arc is equals to the central angle present in the included arc."
According to the question,
∠TPU and ∠UPR are supplementary angles.
Given , ∠UPR = 59°
Therefore,
∠TPU = 180° - 59°
= 121°
∠TPQ + ∠QPR = 180°
∠QPR = 107°
Therefore ,
∠QPR = 180° - 107°
= 73°
As per the definition of arc measure, we conclude
The measure of arc RU is equals to 59degrees.
Hence, central angle of circle P is a angle equals to 121° and 73° and
measure of arc RU is 59 degrees.

Answer:
m<GKH + m<HKI = 180; m<HKI + m<IKJ = 180 - Angles forming a linear pair sum to 180
m<GKH + m<HKI = m<HKI + m<IKJ - Subsitution
m<GKH = m<IKJ - Algebra
<GKH ≅ <IKJ - Definition of congruence
Step-by-step explanation:
Angles that form a linear pair are supplementary because together they make a straight line. So, they must sum to 180.
In statement 2, m<HKI + m<IKJ replaces 180 degrees. This is allowed because m<HKI + m<IKJ is equivalent to 180 degrees, so it can be substituted.
In statement 3, m<HKI is subtracted from both sides. This is allowed through the property of equality, which is a part of algebra.
The definition of congruency is that two shapes that are equal are congruent. So if m<GKH = m<IKJ, then they must be congruent as well.

We can make these both into fractions to make it easier.
3/4=6/10x
Divide both sides by 6/10, or multiply both sides by 10/6.

Use the elasticity to calculate the price that gives a maximum weekly revenue.
dollars per orange
Find this maximum revenue.
dollars of revenue
Answer: See Explanation
Step-by-step explanation:
The price elasticity of demand will be calculated as:
q = 860 − 20p.
dq/do = -20
p = 38
Elasticity E(p) = (p/q) × dq/dp
= [38 /(860 - 20p)] × (20)
=38 × 20/(860 - 760)
= 7.6
Therefore, the price elasticity of demand when the price is $38 per orange is 7.6
Revenue = price × quantity
= p × q
= p × (860 − 20p)
= 860p - 20p²
Differentiating with respect to p
= 860 - 40p
40p = 860
p = 860/40
p = 21.50
Maximum Revenue = 860p - 20p²
= 860(21.50) - 20(21.50)²
= 18490 - 9245
= 9245
Hi, I am having hard time figuring this out. I need to understand the "how to" really well, so as much detail in the solving would be ideal.
Word problem: Tuition fees for California State University were $5,131 during the 2010-2011 academic year. Historically, tuition has increased at an 8% per year rate. Use the formula from Problem 83 to find what the tuition was 20 years ago and 30 years ago. Hint: First solve for P, then substitute the given value for F. Round to the nearest dollar. (equation in #83 to use here is F=P(1+r)² where F is the future price of an item priced at P dollars, r is the inflation rate expressed as a decimal, and t is the time in years)
The given answers for this problem are: 20 years ago, tuition was $1,101 and 30 years ago tuition was $510.
Answer:
For this problem we have:
Initial value P = $5131Increase rate r = 8% or 0.08Time 20 years ago t = -20 30 years ago t = -30Find the value of F using the formula and substitute the values:
F(t) = P(1 + r)^tF(-20) = 5131(1 + 0.08)^(-20) = 1100.84685219 ≈ $1101and
F(-30) = 5131(1 + 0.08)^(-30) = 509.905093313 ≈ $51021 females to 51 males simplified

Answer:
x = -10
Step-by-step explanation:
1) A line creates a 180° angle on each side of it. Even if another line intersects it, we know that the total measure of angles on that side will equal 180°.
2) We set the equations equal to 180.
(-4x) + (-14x) = 180
Combine like-terms
-18x = 180
Isolate x by dividing both sides by -18.
x = -10
3) To solve for each angle, you can plug in -10 for x and solve.
-4(-10) = 40°
-14(-10) = 140°

25x + 15y=17
25x + 15y=305$
Neee answer ASAP
Answer:
1st. Problem
Let's solve for x.
25x+15y=17
Step 1: Add -15y to both sides.
25x+15y+−15y=17+−15y
25x=−15y+17
Step 2: Divide both sides by 25.
25x/25 = -15y+17/ 25
x equals...
x= -3/5 y + 17/25
2nd. Problem
Let's solve for x.
25x+15y=305
Step 1: Add -15y to both sides.
25x+15y+−15y=305+−15y
25x=−15y+305
Step 2: Divide both sides by 25.
25zx/25 = -15y305/25
x equals...
x = -3/5 y + 61/5
