If JL = 9x - 5, LR = 7x - 2, and JR = 35, find JL. Round your answer to the nearest tenth.

Answers

Answer:

JL = 166 units

Step-by-step explanation:

Given that,

JL = 9x - 5, LR = 7x - 2, and JR = 35

Let us assume that, R is the midpoint of J and L. So,

JL = JR + RL

Putting all the values,

9x - 5 =35 + 7x - 2

Taking like terms together as follows :

9x-7x = 33 + 5

2x = 38

x = 19

Put the value of x inm, JL = 9x-5

JL = 9(19)-5

JL = 166

The value of JL is 166 units.

Answers

Step-by-step explanation:

USING RATIONAL ROOT THEOREM:

a = ±2

Factors of a are ±1 ,±2

For the constant term

c= ±18

The factors of c are ±1,±2,±3,±6,±9 and ±18

THE POSSIBLE ZEROES ARE GIVEN BY

c/a=(±1,±2,±3,±6,±9,±18)/(±1 ,±2)

Therefore, the possible zeroes are

±1,±2,±3,±6,±9,±18,±1/2,±3/2,±9/2

Shaun rides his bike at a speed of 19 miles per hour. How far, in miles, does Shaun travel in 25 minutes when rounded to the nearest
hundredth?

Answers

Answer:

Part 1: 1 mile.

Part 2: 1.32 mph.

Step-by-step explanation:

The correct speed of Mariah walks faster than Bobby, in miles per hour - 1 mile per hour.

Shaun travel in 25 minutes in the given case, when rounded to the nearest  hundredth - 7.92 miles.

Part 1.

Given:

speed of Mariah = 6 miles per hour

speed of Bobby = 4, 400 yards per half hour

= 8800 yards per hour

1 mile = 1760 yards

Solution:

To find out the speed difference of both Mariah and Bobby, we need to convert speeds in the same units that is mile:

=> speed of bobby = [tex]\frac{8800}{1760}[/tex]

=> speed of bobby = 5 miles per hour

as it is given 1 mile = 1760 yards

=> Now, the speed difference between Mariah and Bobby is

= 6 - 5

= 1 mile per hour.

Thus, Mariah walks faster than Bobby, in miles per hour - 1 mile per hour.

Part 2:

Given:

Speed of Shaun =  19 miles per hour

distance traveled in 25 minutes = ?

Solution:

To find out the traveled distance by Shaun in 25 minutes we need to find the speed per minute:

1 hour = 60 minutes

So as given, 19 miles per 60 minutes

then speed per minute = [tex]\frac{19}{60}[/tex]

= 0.316

then traveled in 25 minutes-

=> [tex]0.316*25[/tex]

=> = 7.92

Thus, Shaun travel in 25 minutes in the given case, when rounded to the nearest  hundredth - 7.92 miles.

c. The sample standard deviation.
d. s2 using the shortcut method.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

29.5 49.3 30.6 28.2 28.0 26.3 33.9 29.4 23.5 31.6

Sort in ascending order of magnitude :

23.5,26.3,28.0,28.2,29.4,29.5,30.6,31.6,33.9,49.3

A) Range of the sample data:

(maximum - minimum)

49.3 - 23.5 = 25.8

B) sample variance :

S² = ∑ (x − m)²/ n − 1.

m = mean ; n = number of observations

m = (23.5 + 26.3 + 28.0 + 28.2 + 29.4 + 29.5 + 30.6 + 31.6 + 33.9 + 49.3) = 310.3 / 10 = 31.03

∑ (x − m)² = 443.801

n - 1 = 10 - 1 = 9

S² = ∑ (x − m)²/ n − 1

S² = 443.801 / 9

S² = 49.311222 = 49.31

C) The standard deviation (s):

S = √[∑ (x − m)²/ n − 1]

√variance = √49.311222

S = 7.0221949

S = 7.022

D) using statistical calculator,

Find the point P where the line x = 1 + t, y = 2t, z = -3t intersects the plane x + y - z = -5.

Answers

Replace x, y, and z in the plane's equation with their appropriate parametric equations, then solve for t, then evaluate x, y, and z at this t to find the point P.

[tex]x+y-z=-5[/tex]

[tex](1+t)+2t-(-3t)=-5[/tex]

[tex]6t+1=-5[/tex]

[tex]6t=-6[/tex]

[tex]t=-1[/tex]

[tex]\implies x=0,y=-2,z=-3[/tex]

So the point P is (0, -2, -3).

Here, we are required to find the point, P where the lines:

x = 1 + t x = 1 + ty = 2t x = 1 + ty = 2tz = -3t

intersects the plane x + y - z = -5.

The point, P where the lines intersects the plane is given by;

he point, P where the lines intersects the plane is given by;P (0, -2, 3)

Therefore, to find this point, we have to substitute for x, y and z in the equation of the plane.

Therefore, we have;

1 + t + 2t -(-3t) = -5.therefore 6t = - 6and ultimately t = -1

To get the coordinates of the point P where the lines intersect the plane; we can then find x, y and z by substituting t into each of their equations.

Therefore;

x = 1 + (-1) = 0x = 1 + (-1) = 0y = 2(-1) = -2x = 1 + (-1) = 0y = 2(-1) = -2z = -3(-1) = 3

Therefore, the point, P where the lines intersects the plane is given by;

P (0, -2, 3)

Does anyone know how to answer this? The Probability that you draw a mechanical pencil from a group of 25 mechanical and wooden pencils is 3/5. How many are mechanical pencils?

Answers

Answer:

There are 15 mechanical pencils

Step-by-step explanation:

Recall that the probability of drawn a mechanical pencil from a larger group is given by the quotient of the number of mechanical pencils divided the total number of pencils in the sample.

so that means:

[tex]P=\frac{x}{25} \\[/tex]

being x the number of mechanical pencils and 25 the total of all pencils in the sample. Since they give as P as 3/5, we can solve for the number of mechanical pencils (x) using the equation:

[tex]P=\frac{x}{25} \\\\\frac{3}{5} =\frac{x}{25}\\x=\frac{3\,*\,25}{5} \\x=15[/tex]

So there are 15 mechanical pencils in the sample.
