Answer 2

Answer:

Yes

Step-by-step explanation:

Look up Desmos, it is graphing calculator... it will really help. REAL EXPLANATION: You put one point on -4, then do rise over run (2/1x), thus go up to over one. So on and so forth; this will result in a linear line.

Answer:

4

Step-by-step explanation:

We can see from the two marked points the coordinates are: (2, 8) and (4, 16)

That means the rise (vertical change) is 16 - 8 = 8 units. And the run (horizontal change) is (4 - 2) = 2 units.

Therefore slope = rise/run = 8/2 = 4.

Answers

Answer:

v = 60 yards

Step-by-step explanation:

In the similar triangles, their corresponding sides are proportional which means they have equal ratios

In triangles IHG and FHJ

Δ IHG ≈ FHJ

∵ Side IH is corresponding to side FH

∵ Side HG is corresponding to side HJ

∵ Side IG is corresponding to side FJ

→ Their ratios are equal

[tex]\frac{IH}{FH}[/tex] = [tex]\frac{HG}{HJ}[/tex] = [tex]\frac{IG}{FJ}[/tex]

IH = 54 yards and FH = 72 yards

IG = v and FJ = 80 yards

→ Substitute them in the first and last ratios above

∴ [tex]\frac{54}{72}[/tex] = [tex]\frac{v}{80}[/tex]

→ By using cross multiplication

v × 72 = 80 × 54

∴ 72v = 4320

→ Divide both sides by 72

v = 60 yards

How do I solve for the missing angle?!
And please include explanations​ on how you got the answer

Answers

Answer:

75°

Step-by-step explanation:

In triangle FBG, one angle is 36.  That means the other two must total 180-36=144.  Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.

In triangle JDI, one angle is 39.  That means the other two must total 180-39=141.  Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5

We now have 4 of the interior angles.  Pentagons have an interior total of 540.  540-108-108-109.5-109.5=105

x is the supplement of 105.  180-105=75

What type of association is shown by the data in the scatter plot?

Answer Choices:

A. positive association

B. negative association

C. no association

D. trend association

Answers

Answer: B) Negative association

=================================================

Explanation:

We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.

Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.

-----------------

Extra info:

Positive linear association would be when x and y go up together, or go down together. The variables go in the same direction together. The regression line would have positive slope.Points with no linear association would either be randomly scattered points, or perhaps another function type (eg: quadratic) would fit the points. The term "trend association" just seems to be something your teacher made up in order to possibly confuse students.

Step-by-step explanation:

Joseph's age is unknown, so we will use j. It says the quotient of Joseph's age (j) and 2, so it would be j/2, or j divided by 2.

Then it says that George is 3 years older, so that would be addition.

Therefore, it would be:

Include an equation to show your work. Explain your thinking.? Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!

Answers

Answer:

She rode 17.4 miles in 1 hour

Step-by-step explanation:

A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?

Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?

The quotient is the average speed and this is calculated as:

Speed = Distance(miles)/Time(hours)

Where speed = quotient

Distance = Dividend

Time = Divisor

Speed = 60.9 miles/3.5 hours

= 17.4 miles/hour

Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!

If :

3.5 hours = 60.9 miles

1 hour = x miles

Cross Multiply =

3.5x = 60.9 miles

x = 60.9/3.5

x = 17.4 miles

Hence, she rode 17.4 miles in 1 hour

Throughout human history, dreams have terrified, thrilled, andinspired us. But what do they mean? What is their purpose? Thisessay will provide several explanations from various fields andraise a few questions about dreams that are yet to be answered,2. What qualifies as a dream exactly? The term dream can refer toour hopes about the future, as in, "One day I dream of visitingParis." Dreams can also refer to waking fantasies that we largelyhave control over, such as daydreams. However, the scientificfield of oneirology is concerned with what happens when wesleep. "For a dream to be a dream, it has to be an involuntaryexperience that occurs during the Rapid Eye Movement, or REM,stage of sleep," says neuropsychologist Martin Dyson, "All otheruses of the word dream fall outside the domain of science."While all types of dreams are important, it is these nighttimedreams that truly fascinate us3. In a typical night's rest, REM sleep is the stage that happens inthe final few hours before we wake up in the morning. In TheScience of Dreams and the Dreams of Science, author IsabellaGreene explains that this stage of sleep is marked by brainactivity that is similar to the brain activity of people who areawake (224). Sleepers have experiences during REM sleep, justas waking people do. Some scientists think that during REMsleep the brain clears out our short-term memory and commitsimportant experiences, such as getting a raise or breaking upwith our sweethearts, to long-term memory. But why we dreamduring this process is still a mystery4. Some intriguing, though incomplete, ideas have come fromresearchers trying to explain why our brains give us such vividand emotional experiences every night. Sigmund Freud believedthat dreams are expressions of memories and anxieties that weavoid-thinking about during our waking lives. Carl Jung provideda modern version of the ancient opinion that dreams aremessages that help us figure out how to avoid disaster, almostlike prophecies. Perhaps the popularity of Jung's interpretation isthe reason that many people keep dream journals, where in theywrite down their dream experiences before they forget them.After all, if dreams are messages, one had better not ignorethem.5. But interpreting dreams seems to be a basic human desire, andinterpretations of dreams predate modern psychology by manyyears. The ancient Sumerians, Chinese, and Indians believed that,during dreams, the soul escapes from the body to wander in aspiritual realm. The ancient Greek physician, Hippocrates,theorized that the soul creates its environment when one isasleep and receives its environment when one is awake. Giventhat modern science has yet to explain dreams, any ancientinterpretation is as good as a modern one for now. Perhaps oneday that won't be the case.6. Until the truth behind dreams is finally revealed, people willcontinue to speculate about their purpose. And even if the role ofdreams is finally articulated, dreams will continue to haunt us,fascinate us, and move us.Which is the best example of a description paragraph in the essay?A. Paragraph 2B.
