Given:

The equation of the line of best fit is :

[tex]y=4.722392638x+50.99539877[/tex]

To find:

The x-intercept and check whether it make sense in this context.

Solution:

We have,

[tex]y=4.722392638x+50.99539877[/tex]

Substitute [tex]y=0[/tex] to find the x-intercept of the given best fit line.

[tex]0=4.722392638x+50.99539877[/tex]

[tex]-50.99539877=4.722392638x[/tex]

[tex]-\dfrac{50.99539877}{4.722392638}=x[/tex]

[tex]-10.7986359202=x[/tex]

So, the x-intercept is at point (-10.7986359202,0). It means the score on final examination is 0 if -10.7986359202 hours  spent on studying.

But is does not make sense because the number of hours cannot be negative.

Answer:

Step-by-step explanation:

So you want to isolate the y, so add 4x to both sides of the problem. So now we have y < -7 + 4x. Now since adding can go both ways (in its own equation) you can turn around the 7 and 4. So we have y < 4x -7

Answer:

t = 68000 s

Step-by-step explanation:

Given that,

The average time Sally spent for training for her weight lifting competition in the month of May is [tex]6.8\times 10^4\ s[/tex].

We need to write this time in standard notation.

The power of 10 is 4. 10⁴ can be written as 10000.

[tex]6.8\times 10^4=\dfrac{68}{10}\times 10000\\\\=68000[/tex]

So, the standard time is equal to 68000 s.

Answer:

4695.90

Step-by-step explanation:

The exponential growth function is given as:

y = a(1 + r)^t

a = Initial value = 390

y = Value after time t = ?

r = Growth rate = 5% = 0.05

t = Time in years =51

Hence

y = 390(1 + 0.05)⁵¹

y = 4695.9002123

Approximately = 4695.90

Answer:

B

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{g}{18\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2g = 54 ( divide both sides by 2 )

g = 27 → B

The angles surrounding the point p are 90 degrees

Then using the angle given, find the missing angles.

JPH = 90

HJP = 49

90+49 = 139

180 - 139 = 41

Therefore JHP = 41

HLP = HJP = 49

HLP = 49

KLP = 72

KLP + HLP = 72 + 49 = 121

Therefore, HLK = 121

LP = JP = 16

JP = 16

HL = HJ = 13

HL = 13

Answer:

The team is measuring at 364 ft below the surface

Step-by-step explanation:

Here, we want to get the depth at which the pressure was measured at

to get this, we will have to use the equation that relates the pressure to the depth

From the question, we have this as;

P = 13 + 8/13(d)

From the question, P is 237

Substituting this into the equation, we have

237 = 13 + 8/13(d)

237-13 = 8/13(d)

224 = 8/13(d)

8d = 13 * 224

d = (13 * 224)/8

d = 364 ft

Answer:

The length of legs lm, mn, and lk is 32 while that of kn is 36.

Step-by-step explanation:

The diagram is attached in the answer.

As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk

This leads the two set of legs such as

[tex]\dfrac{lm}{kn}=\dfrac{8}{9}[/tex]

Or this could be written as

[tex]lm=8x\\kn=9x[/tex]

Now the remaining two sides are given as

[tex]lk=lm[/tex] as this form an isosceles triangle so

[tex]lk=8x[/tex]

Similarly

[tex]mn=lm\\[/tex]

Or

[tex]mn=8x[/tex]

Now the perimeter is given as

[tex]\text{perimeter}=lm+mn+kn+lk\\[/tex]

Here perimeter is given as 132 so this gives:

[tex]\text{perimeter}=lm+mn+kn+lk\\132=8x+8x+8x+9x\\132=33x\\x=\dfrac{132}{33}\\x=4[/tex]

So the four legs are of length as given below:

[tex]lm=8x=8\times 4=32\\mn=8x=8\times 4=32\\lk=8x=8\times 4=32\\kn=9x=9\times4=36[/tex]

So the length of legs lm, mn, and lk is 32 while that of kn is 36.

Step-by-step explanation:

can i get brainly

Answer:

- 6, - 21, 12

Step-by-step explanation:

(1)

2x - 7 = - 19 ( add 7 to both sides )

2x = - 12 ( divide both sides by 2 )

x = - 6

(2)

[tex]\frac{x}{-3}[/tex] + 5 = 12 ( subtract 5 from both sides )

[tex]\frac{x}{-3}[/tex] = 7 ( multiply both sides by - 3 to clear the fraction )

x = - 21

(3)

[tex]\frac{3}{4}[/tex] x - 5 = 4 ( add 5 to both sides )

[tex]\frac{3}{4}[/tex] x = 9 ( multiply both sides by 4 to clear the fraction )

3x = 36 ( divide both sides by 3 )

x = 12

Answer: [tex]235^{\circ}[/tex]

Step-by-step explanation:

Given

The Sum of the seven interior angles of an octagon is [tex]845^{\circ}[/tex]

for a Polygon, the sum of the interior angles is given by [tex](n-2)180^{\circ}[/tex]

for octagon, n=8

The Sum of interior angles is [tex](8-2)360^{\circ}=1080^{\circ}[/tex]

Suppose the eighth angle be [tex]x[/tex]

[tex]\therefore x+845=1080\\\Rightarrow x=235^{\circ}[/tex]

The [tex]8^{th}[/tex] angle is [tex]235^{\circ}[/tex]

Answer:

Below.

Step-by-step explanation:

One standard form of the equation of a straight line is

y = mx + c where m = the slope and c = the y-intercept.

Comparing this with y = 3x - 6 we see that:

The slope = 3 and the y-intercept is -6.

The error was in the y-intercept.

#2.

The error is in stating the intercepts

x - intercept is (8, 0) and y-intercept = (0, 2), (NOT (8, 2)).

#3.

The error is in stating the intercepts

x - intercept is (5, 0 and y-intercept = (0, 2).
