Answer:

(a) Regression Equation : x = 6.33333y + 38.6875,

(b) Test Score will be about 89.4% if student sleeps 8 hours a night

Step-by-step explanation:

Using a regression calculator your equation should be as follows, where x = test scores, and y = average sleep.

(a) Solution : x = 6.33333y + 38.6875

We can check if this equation is ' suitable ' by plugging in the value 7 for y, and expecting an outcome of around 88 percent ...

x = 6.33333(7) + 38.6875 = 44.33331 + 38.6875

= 83.02061% - this may seem a bit too off, but it is predictable

Now let's plug in 8 for y, as to calculate the percent when a student sleeps for 8 hours ...

x = 6.33333(8) + 38.6875 = 50.66664 + 38.6875

= 89.35414% ≈ 89.4%

(b) Solution : Test Score will be about 89.4%

What's 5(m−2)−10=6+2(1−m)

Answers

 Answer:  m=4

Step-by-step explanation:

5(m-2) - 10 = 6 + 2(1 - m)  Apply the distributive property on both sides

5m -10 -10 = 6 + 2-2m         Now combine like terms on both sides

5m -20 = 8- 2m     Now add 2m to both sides

+2m              +2m

7m  - 20= 8    Add 20 to both sides

        +20  +20

7m = 28      Divide both sides by  7

m = 4

Question 4 Find the value of a and YZ if Y is between X and Z.

XY = 3a - 4, YZ = 6a + 2, XZ = Sa + 22

a=?
YZ=?​

Answers

Answer:

a = 6YZ = 38

Step-by-step explanation:

The segment addition theorem tells you ...

  XY +YZ = XZ

  (3a -4) +(6a +2) = (5a +22)

  4a = 24 . . . . . . . . add 2-5a and simplify

  a = 6 . . . . . . . . . . divide by 4

Then the length of YZ is ...

  YZ = 6a+2 = 6(6) +2

  YZ = 38

5-9(8 - 2x) < 2x - 115 solve for x​

Answers

Answer:

x < -3

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

5 - 9(8 - 2x) < 2x - 115

Step 2: Distribute parenthesis

5 - 72 + 18x < 2x - 115

Step 3: Combine like terms

-67 + 18x < 2x - 115

Step 4: Add 67 on both sides

18x < 2x - 48

Step 5: Subtract 2x on both sides

16x < -48

Step 6: Divide both sides by 16

x < -3

And we have our answer!

Answer:

x<-3

Step-by-step explanation:

5−9(8−2x)<2x−115

Use the distributive property to multiply −9 by 8−2x.

5−72+18x<2x−115

Subtract 72 from 5 to get −67.

−67+18x<2x−115

Subtract 2x from both sides.

−67+18x−2x<−115

Combine 18x and −2x to get 16x.

−67+16x<−115

Add 67 to both sides.

16x<−115+67

Add −115 and 67 to get −48.

16x<−48

Divide both sides by 16. Since 16 is >0, the inequality direction remains the same.

x<-48/16

Divide −48 by 16

x<−3

When a problem involves more than one unit for a characteristic (such as length), now can you tell which unit is more appropriate to report the answer in?

Answers

Answer:

For larger measurements, we use larger unit while for smaller measurement we use smaller unit.

Step-by-step explanation:

Normally, For larger distances we make use of larger units while for smaller distances we make use of smaller units.

For example, if we consider the distance travelled by a person in some days;

For 15000 units distance; We can represent this value as 15 Kilometers

For 800 units distance; Rather than using kilometers, it would be better to represent it in meters as 8 meters.

Also, For 70 units distance; Instead of kilometers or meters, 70 cm would be a better unit of representation.

Likewise, If we consider some 3 dimensional shapes holding some substances,

For 7000 units, best unit of weight representation would be 7 Kg

For 600 units, instead of in kg, best unit of weight representation would be 600 grams

For 50 units, best unit of weight representation would be 50 grams

So, looking at the examples given in both weight and distances, we will conclude that for larger measurements, we use larger unit while for smaller measurement we use smaller unit.

A ship travels a distance of 200 nautical miles in 10 1/2 hours. how many knots did the ship average each hour? (One knot equals 1 nautical mile per hour) Provide explination please

Answers

Answer:

19.05 knots average per hour

Step-by-step explanation:

Distance traveled = 200 nautical miles

Time taken = [tex]10\frac{1}{2}[/tex]  hours = [tex]\frac{10\times2+1}2=\frac{21}{2}[/tex] hours

To find:

How many knots did the ship average each hour ?

Solution:

Here, we are given the distance traveled and total time taken to travel the distance.

As per question statement, we have to find the average speed of the ship.

Formula for average speed is given as:

[tex]\text{Average Speed = }\dfrac{\text{Total Distance traveled}}{\text{Total Time Taken}}[/tex]

Putting the values in the formula:

[tex]\Rightarrow \text{Average Speed = }\dfrac{200}{\frac{21}{2}}\\\Rightarrow \text{Average Speed = }\dfrac{200\times 2}{21}\\\Rightarrow \text{Average Speed = }\dfrac{400}{21}\\\Rightarrow \text{\bold{Average Speed = 19.05 nautical miles per hour}}[/tex]

It is also given that 1 nautical mile per hours is equal to one know.

Therefore, the average speed can be written as:

19.05 knots average per hour

What is the solution to this system of equations?
x + 3y - z = 6
4x - 2y + 2z= -10
6x + z= -12

(an explanation would be great because i barely understand how to do this)

Answers

Answer:

[tex]x=-3, y=5, z=6[/tex]

Step-by-step explanation:

1. Divide by 2 both sides in the second equation:

[tex]4x - 2y + 2z= -10[/tex] [tex]2x - y + z= -5[/tex]

2. From the third equation find z in terms of x:

[tex]6x + z= -12[/tex] [tex]z= -6x-12[/tex]

3. Add up the first and new second equations and find y in terms of x:

[tex](x+2x)+(3y-y)+(-z+z)=6+(-5)[/tex] [tex]3x+2y=1[/tex] [tex]2y=1-3x[/tex] [tex]y=0.5-1.5x[/tex]

4. Put new alternatives instead of y and z in the first equation:

[tex]x+3(0.5-1.5x)-(-6x-12)=6[/tex] [tex]x+1.5-4.5x+6x+12=6[/tex] [tex]2.5x=-7.5[/tex] [tex]x=-3[/tex]

5. Now we can easily find other two unknowns by using their equations by means of x:

[tex]y=0.5-1.5\times(-3)[/tex] [tex]y=0.5+4.5[/tex] [tex]y=5[/tex][tex]z=-6\times(-3)-12[/tex] [tex]z=18-12[/tex] [tex]z=6[/tex]

Answer:

Step-by-step explanation:

2x + 6y - 2z = 12

12x - 6y + 6z = -30

14x + 4z = -18

6x + z = -12

14x + 4z = -18

-24x - 4z = 48

-10x = 30

x = -3

6(-3) + z = -12

-18 + z = -12

z = 6

-3 + 3y - 6 = 6

-9 + 3y = 6

3y = 15

y = 5

x = -3, y = 5, z = 6

To solve for x, multiply both sides by 11.

[tex](11)\frac{x}{11}=(11)\frac{13}{11}[/tex]

Both the left and the right cancel. Thus:

[tex]x=13[/tex]

A line passes through the points (2,3) and (6,y) with a slope of 2. What is the value of y?

Answers

Answer:

5

Step-by-step explanation:

The slope of a line is always rise over run.

We need to make the rise over run equivalent to 2 to find the value of y.

Looking at the x-coordinates, 2 and 6, we can see there is an increase in 4.

Now we ask: What number, times 2, will equal 4?

That is 2.

So we have to make the increase in the y coordinates 2.

If we have the original point 3, an increase in 2 is 5.

So y is 5.

Hope this helped!

Answer:

11 = y

Step-by-step explanation:

Using the slope formula

m = (y2-y1)/(x2-x1)

2 = (y-3)/(6-2)

2 = (y-3)/4

Multiply each side by 4

2*4 = y-3

8 = y-3

Add 3  to each side

8+3 = y-3+3

11 = y

The estimate would be 3-0= nothing​, so her answer is not reasonable. D. The estimate would be 3-0= nothing​, so her answer is reasonable.

Answers

Answer:

The estimate would be 3-0= nothing​, so her answer is not reasonable.

Step-by-step explanation:

Given the expression written by Elizabeth as  3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.

Converting 3.3 and 0.21 to fraction

3.3 = 33/10

0.21 = 21/100

Taking the difference of both fractions

[tex]= \dfrac{33}{10} -\dfrac{21}{100} \\\\= \dfrac{330-21}{100} \\\\= \dfrac{309}{100} \\\\= 3.09\\[/tex]

Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). This large difference makes Elizabeth answer unreasonable.

D.

The estimate would be 30

Source 1 "The government of Peru was a despotism, mild in its character, but in its form a pure and unmitigated despotism. The sovereign was placed at an immeasurable distance above his subjects. Even the proudest of the Inca nobility, claiming a descent from the same divine original as himself, could not venture into the royal presence, unless barefoot, and bearing a light burden on his shoulders in token of homage. As the representative of the Sun, he stood at the head of the priesthood, and presided at the most important of the religious festivals. He raised armies, and usually commanded them in person. He imposed taxes, made laws, and provided for their execution by the appointment of judges, whom he removed at pleasure. He was the source from which every thing flowed, all dignity, all power, all emolument. He was, in short, in the well-known phrase of the European despot, himself the state. William Hickling Prescott, American scientific historian, excerpt from History of the Conquest of Peru, 1847 Source 2 "By night and day they [human offerings] burned, supplied with fuel by an army of slaves who brought it on their backs over the long causeways that connected the island-city with the mainland and its distant forests. These pillars of smoke by day, and ill-omened banners of flame by night, were regarded with fear and hatred by many a dweller in the mountains surrounding the Mexican valley. They were the symbols of a power against which these had struggled in vain, of a tyranny so oppressive that it not only devoted them to lives of toil, hopeless of reward, but to deaths of ignominy and torture whenever fresh victims were demanded for its reeking altars. But while hatred thus burned, fierce and deep-seated, none dared openly to express it, for the power of the all-conquering Aztec was supreme. Far across the lofty mountains, to the great Mexican Gulf on the east, and westward to the broad Pacific; from the parched deserts of the cliff-dwelling tribes on the north, to the impenetrable Mayan forests on the south, the Aztec sway extended, and none might withstand the Aztec arms.
