Answer:
x + y = -6
Step-by-step explanation:
Answer:
y = -x-6
Step-by-step explanation:
For this problem we use point-slope formula:
y-y1 = m (x2-x1)
When we plug in our values, it looks like this:
y-(-1) = -1 (x-(-5))
When we rearrange into slope-intercept form, we get this:
y = -x-6

Find the value of x and y.
Answer:
x = 30
y = 2
Step-by-step explanation:
Please note: the value for x is correct only if this triangle is a right triangle.
This can be solved because 2(5y) = 20 and because if a triangle has all congruent angles then its side lengths are also congruent.

do the set of favourite colours form a set
Answer:
Step-by-step explanation:
Our preference for a specific color can be related to how we feel in any situation, how we want to feel, and even how we remember certain experiences (to name a few). This section, which is closely associated with the previous section color Associations, presents the survey participants preferences and how they vary between age groups and gender. This first section examines the question of favorite color for all participants regardless or gender or age. Figure 6.1 below presents this information in graphical form.Blue, for this group of people, is the most favored choice of the 8 colors available. Blue is an interesting color in that people tend to choose it as a favorite, but it is usually associated with sadness and depression. Birren notes that blue is commonly associated with adjectives like cold, subduing, sober, gloom and fearfulness (Color Psychology and Color Therapy, 143). Although some studies have suggested that blue can represent feelings that are sad or not happy, people tend to like the hue of blue (and like colors) because they have a calming and relaxing
When this data is examined further and filters of gender and age are applied, some interesting results surface. The two pie charts below represent favorite colors of each
A review of color studies by Eysenck in the early 1940’s notes that St. George (1938) maintained that blue for men stands our far more than for women. Related to different colors, Eysenck’s study also found that the most significant gender difference is yellow being preferred to orange by women and orange to yellow by men. Natalia Khouw states, “this finding was reinforced later by Birren in 1952 who found men preferred orange to yellow; while women placed orange at the bottom” (The Meaning of Color for Gender, 1). Both these published results correlate to the survey results collected in this
color preferences differ by the age of the participant. Birren states in his book that blue and red maintain a high preference throughout life, but colors seem to drop down the list while other colors become more preferred. Yellow, for example, is well liked by children, but begins to drop away by people as they become adults. Birren states, “With maturity comes a greater liking for hues of shorter wave length (blue, green, purple) than for hues of longer wave length (red, orange, and yellow)” (Color Psychology and Color Therapy, 176). Below is a graphical representation of the survey results for a favorite color by age group.
As you can see, blue, green, and purple make up the majority of responses. What’s interesting is the preference of green in the younger age groups and the preference of purple in the older age groups. One could say, by looking at this graph alone, that as people become older their preference for purple increases, while their preference for green decreases. Previous academic or research publications regarding this specific anomaly were not found during this project so the ability to compare and contrast these results with other results isn’t possible at this time. M. M. Terwogy and J. B. Hoeksma did a research study on colors and emotions with regards to preferences and combinations and they noted that as people get older, their preferences are likely to change as a result of social and cultural influences. They state, “As children grow up they learn that the expression of anger is often punished. They also learn that the color black (within Western culture) is associated with mourning.” (Color and Emotions, 7) They also state that the effects of color preferences are still present at later stages of life, but these preferences are outweighed by other (as yet unidentified) factors (Color and Emotions, 16).
The least favorite color graph (shown below) was mentioned on the “color Associations” page along with what people tend to associate cheap and inexpensive. Below is a graphical representation of the survey results for least favorite color for all ages and both .
As you can see orange, brown, and yellow comprise the majority of responses. As you’ve already read, yellow (according to Birren) tends to drop from preferred to disliked as a person grows older. Also, Birren stated in 1951 that women tend to put orange at the bottom of their preference list. Brown, being a darker hue of orange may share some similarities with orange. An interesting detail about orange is the love / hate relationship people have with it as a color. According to the survey results, orange took 28% of the votes when associated with “Fun.” Also, according to Birren the adjectives that his participants gave to orange are: bright, luminous, glowing, warm, metallic, autumnal, jovial, lively, energetic, hilarity and exuberance. All of these adjectives, to me, seem positive. One hypothesis could be that the dislike of the color orange is of stylistic consequence. That is, orange may be going through a period of being out of style, at least in comparison
One cup holds 100 grams of sugar. How many cups will hold half a kilogram of sugar?
Answer:
5 cups
Step-by-step explanation:
1 kilogram is 1000 grams
1/2 of a kilogram is 500 grams
Answer:
5 cups
Step-by-step explanation:
Half a kilogram is 500 grams.
500 grams is 5 times bigger than 100 grams.
Which means it takes 5 times more cups to hold 500 grams.
100 grams = 1 cup
500 grams = 5 cups
Write the equation for (-8, -8), with a slope if three
Answer:
Part--1:
We know that a equation in point-slope form is represented by:
y-y1=m
where m is the slope of the line and is a point through which the line passes.
Consider a equation in a point-slope form as:
This means that the slope of the line is: 5
and the line passes through the point (1,5).
Part--2:
Now as we know that if a line has a slope as m then the perpendicular line has a slope: -1/m
Since,
Let this perpendicular line passes through (2,6)
Hence, the equation of a line in point slope form is given by:
Step-by-step explanation:
A man is in a boat 2 miles from the nearest point on the coast. He is to go to point Q, located 3 miles down the coast and 1 mile inland (see figure). He can row at a rate of 4 miles per hour and walk at 4 miles per hour. Toward what point on the coast should he row in order to reach point Q in the least time?
Answer:
The answer is "0.45385".
Step-by-step explanation:
The time is taken to reach the coast [tex]= \frac{\sqrt{(2^2 + x^2)}}{4}[/tex]
The time is taken to reach Q after reaching the coast [tex]= \frac{\sqrt{(1 + (3-x)^2)}}{4}[/tex]
Total time, [tex]T= \frac{\sqrt{(1 + (3-x)^2)}}{4}+ \frac{\sqrt{(1 + (3-x)^2)}}{4}[/tex]
This has to be minimum,
[tex]\to \frac{dt}{dx} = 0[/tex]
[tex]\to \frac{\sqrt{(2^2 + x^2)}}{2} + \frac{\sqrt{1 + (3-x)^2}}{3}\\\\ \frac{x}{4}\sqrt{(4+x^2)} + \frac{(x-3)}{(4\sqrt{(x^2-6x+10)}} = 0\\\\\frac{x^2}{16} \times (4+x^2) = \frac{(x-3)^2}{16 \times (x^2-6x+10)}\\\\x^2(4+x^2) = \frac{(x-3)^2}{(x^2-6x+10)}\\\\4x^2+x^4 = \frac{ x^2+9-6x}{(x^2-6x+10)}\\\\ 4x^2+x^4(x^2-6x+10) = x^2+9-6x\\\\4x^4-24x^3+40x^2+x^6-6x^5+10x^4= x^2+9-6x\\\\x^6-6x^5+ 14x^4-24x^3+39x^2+6x-9=0\\\\[/tex]

The numbers 1 to 13 are written on 13 separate slips of paper and placed into a box. A slip of paper is randomly drawn from the box. Express probabilities as reduced fractions and as decimals rounded to 3 decimal places. 1. a. What is the probability that the slip of paper has an odd number on it? 1. b. What is the probability that the slip of paper has a number less than 4 on it? Theoretical probability can be used to predict the likelihood of an event. If a single, 6-sided die is rolled there are six possible outcomes. That is, after rolling the die, the side facing up will show one of six possibilities: 1, 2, 3, 4, 5, or 6. The theoretical probability that the die would land with a "2" on the side facing up is P = 1/6 = 0.167 because one out of the 6 possibilities is a "2." MGF2106 Project 2B; SP2020 5 2.

What is an equation of the line that passes through the points (−6,−2) and (6, 8)
Answer: [tex]y=\frac{5}{6}x+3[/tex]
Step-by-step explanation:
To find the equation of the line with the given points, we want to first find the slope then the y-intercept. We use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]m=\frac{8-(-2)}{6-(-6)} =\frac{10}{12}=\frac{5}{6}[/tex]
Now that we know the slope, we can use one of the points to find the y-intercept.
[tex]8=\frac{5}{6}(6)+b[/tex] [multiply]
[tex]8=5+b[/tex] [subtract both sides by 5]
[tex]b=3[/tex]
Now, we know the equation is [tex]y=\frac{5}{6}x+3[/tex].

Find the slope of the line through each pair of points plz
Answer:
-1/2
Step-by-step explanation:
slope = m = (y2 - y1)/(x2 - x1) = (-2 - (-5))/(11 - 17) = 3/(-6) = -1/2
Answer:
Slope= [tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
When you are looking for slope you should use this [tex]slope=m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] then just plug in what you already know.
[tex]y_{1}=-5\\y_{2}=-2\\x_{1}=17\\x_{2}=11[/tex]
Now we insert it in the formula and solve to get the slope...
[tex]\frac{-2-(-5)}{11-17}=\frac{3}{-6}=-\frac{1}{2}[/tex]
The _________ of a hypothesis test is the probability (1minus beta) of rejecting a false null hypothesis.
Answer:
Power
Step-by-step explanation:
An hypothesis is usually formulated at the beginning of research, it is usually in line with the problem statement and gives the possible outcome.
An hypothesis is either accepted or rejected.
Power in hypothesis is the probability of rejecting null hypothesis when it is false. It helps in making a correct decision by rejecting the null hypothesis when it is not true.
power ranges between 0 to 1 when it is close to 1 it is said to be very strong and has the probability of rejecting a null hypothesis when it is not true.
Power helps to avoid a type II error in statistics.

An online store holds a sale. Of the 500 customers who make purchases during the sale, 220 use a coupon. What percent of the customers do not use a coupon?
Answer:
56 %
Step-by-step explanation:
Total no of customers = 500
Used coupon = 220
Not used coupon = 500 - 220 = 280
We need to find the percentage of the customers do not use a coupon. It can be given by :
[tex]\%=\dfrac{280}{500}\times 100\\\\=56\%[/tex]
So, there are 56% of the customers that do not use a coupon.
