The femur or thigh bone of an average human is 480 millimeters long. The spinal cord of an average human is 45 centimeters long. What is the total length of a spinal cord and a femur in meters

PLEASE NEED HELP

Answer:

5 feet

Step-by-step explanation:

1 second =-3 inches what of

4 seconds=?

-3×4÷1=-12 inches

-12 inches =-1 foot

6 feet + (-1) foot= 5 feet

Answer:

d= 4t

Step-by-step explanation:

to find distance, the equation is speed multiplied by time and in this question we are given the time and distance so we have to divide 9km by 2.25hrs to find the speed: 9÷2.25= 4 so, the equation would be d=4t which means that to find distance we need to multiply 4 by the time.

Answer:

x = 25

∠A = 125

Step-by-step explanation:

∠A = ∠B

where

∠A = 6x + 5°

∠B = 4x + 45°

6x + 5° = 4x + 45°  

6x - 4x = 45 - 5

2x = 40

x = 40/2

x = 20

plugin x into  ∠A = 6x - 5°  

∠A = 6x + 5°

∠A = 6(20) + 5°

∠A = 125

Answer:

x = 25

A = 145

Answer:

f(9) = 90

Step-by-step explanation:

f(x) = 9+ x^2

Let x = 9

f(9) = 9+ 9^2

     = 9 + 81

    = 90

Answer:

f(9) =90

Step-by-step explanation:

[tex]f(x) =9+x^2\\\\f(9)=?[/tex]

Substitute ; x = 9 into  the given function

[tex]f(9) = 9+(9)^2\\\\f(9) = 9+81\\\\f(9) = 90[/tex]

Solution :-

Given ratio to us is 60 : 48 and we are required to convert it into simplest form .

For this first find the HCF of 60 and 48 .

= 48 ) 60 ( 1

- 48

__________

12 ) 48 ( 4

- 48

__________

0

Hence the HCF ( 60,48 ) is 12 .

Now divide the given ratio by 12 .

= [tex]\sf \dfrac{60\div 12}{48\div 12}[/tex]

= [tex]\sf \dfrac{5}{4}[/tex]

=[tex]\sf 5:4[/tex]

Answer:

x > −4

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

3x+24>12

Step 2: Subtract 24 from both sides.

3x+24−24>12−24

3x>−12

Step 3: Divide both sides by 3.

3x/3 > −12/3

x>−4

Answer:

x>−4

Hey there!

ANSWER: [tex]\frac{9}{10}[/tex]

EXPLANATION:

[tex]3/8[/tex] ÷ [tex]5/12[/tex]

Make the numerator 12 and denominator 5.

[tex](\frac{3}{8})(\frac{12}{5})[/tex]

Now put both numerators together and the denominators together.

[tex]\frac{(3)(12)}{(8)(5)}[/tex]

Now multiply numerator by numerator and denominator by denominator.

Numerator:

[tex]3*12=36[/tex]

Denominator:

[tex]8*5=40[/tex]

[tex]\frac{36}{40}=\frac{9}{10}(ANSWER)[/tex]

Answer:

it would be what ever number is to the right of 7  but its just a . for me

Step-by-step explanation:

Answer:

x<_2

Step-by-step explanation:

first off solve this like a regular equation the >_ dosent matter till later

so basically first multiply - by 13 and -x so you get -13 and x (multiplying two negatives = a positive)

so its 5x-13+x>_9x-7

add 5x and x to get 6x-13 on one side

then you get 6x-13>_9x-7 then subtract -9x from both sides

so its now -3x-13>_-7 add 13 so you get -3x>_6

then divide both sides by -3 (when you divide an equation with a >< or <_ >_ by a negative number that sign switches) so it will now be x<_2

that your final answer hope this helps :)

Answer:

isnt 9?

Step-by-step explanation:

i asked google lololol

Answer:

9.

Step-by-step explanation:

Factors of 27: 1, 3, 9, 27

Factors of 45: 1, 3, 5, 9, 15, 45.

The GCF (Greatest Common Factor) of 27 and 45 is NOT 1, 3, or 27 because 27 is not a factor of 45, and since we are trying to figure out the GREATEST common factor, one and three do not work either.

Answer:

[tex] V = \frac{10}{3} \pi r^2h [/tex]

Step-by-step explanation:

The cone has the following given dimensions:

Radius = r

Height = h

Volume of a cone = ⅓πr²h

The Cylinder has:

Radius = r

Height = 3h

Volume of the cylinder = πr²h = πr²*3h = 3πr²h

Volume of the cement post = volume of Cone + volume of Cylinder

Equation to find total volume of cement post:

V = ⅓πr²h + 3πr²h

[tex] V = \frac{\pi r^2h}{3} + \frac{3 \pi r^2h}{1} [/tex]

[tex] V = \frac{1(\pi r^2h) + 3(3 \pi r^2h)}{3} [/tex]

[tex] V = \frac{\pi r^2h + 9 \pi r^2h}{3} [/tex]

[tex] V = \frac{10 \pi r^2h}{3} [/tex]

[tex] V = \frac{10}{3} \pi r^2h [/tex]

Follows are the solution to this question:

Step-by-step explanation:

The Ford car has an issue rate of 1.27.  

That means that [tex]\lambda = 1.27[/tex]

Here, [tex]X \sim poisson (\lambda = 1.27)[/tex]

In option (A) :

To make a random variable X a Poisson variable,  Parameter:

[tex]\to \lambda \leq 0 .[/tex]

The likelihood of success decreases with increased test numbers.  

Mathematics, as [tex]n \longrightarrow \infty, \ \ \ and \ \ \p \longrightarrow 0[/tex].

In option (B) :

You must find it: [tex]P(X =0)[/tex]

[tex]\to P(X=0) = \frac{e^{-\lambda}\cdot \lambda^{0} }{0!} \\\\\to \lambda= 1.27 \\\\=e^{-1.27} \\\\= 0.280832[/tex]

In Option (C):

You must find it: [tex]P( X \leq 2) \\[/tex]

[tex]\to P( X \leq 2) = P(X=0) +P(X=1)+P(X=2) \\\\= \sum_{x= 0}^{2} P(X=x) \\\\= \sum_{x= 0}^{2} \frac{e^{- \lambda} \lambda^{x} }{x!} \\\\= e^{-1.27}\sum_{x= 0}^{2} \frac{ 1.27^{x} }{x!} \\\\ = 0.863964[/tex]

In Option (d):

Its first rating is essential because failures in production could be detected  but before the total product becomes defective, this can be reduced.

In Option (e) :

The Toyata car has an issue rate of 1.12  

That means that [tex]\lambda = 1.12[/tex]  

Here, [tex]Y \sim poisson ( \lambda= 1.12)[/tex]

In Option (f):

You must find it: [tex]P(Y=0)[/tex]

[tex]\to P(Y=0)= \frac{e^{- \lambda } \lambda^{0}}{0!} \\\\\to \lambda = 1.12 \\\\=e^{-1.12}\\\\= 0.32628 \\[/tex]

You must find it: [tex]P(X \leq 2)[/tex]

[tex]\to P( X \leq 2) = P(Y=0) +P(Y=1)+P(Y=2) \\\\= \sum_{x= 0}^{2} P(Y=y) \\\\= \sum_{x= 0}^{2} \frac{e^{- \lambda} \lambda^{y} }{y!} \\\\= e^{-1.12}\sum_{x= 0}^{2} \frac{ 1.27^{y} }{y!} \\\\= 0.896356[/tex]

Comparing [a], [b], for the ford car and [b] and [c] for Toyot effectiveness  

Car, its probability that less faults with Toyota car are strong, that's why it's better

   3 =  —  =  —————

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero

7.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, then multiplies both sides of the equation by the denominator.

Here's how:

 -6•(x-6)

 ———————— • 3 = 0 • 3

    3    

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -6  •  (x-6)  = 0

Equations which are never true:

7.2      Solve :    -6   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

7.3      Solve  :    x-6 = 0  

Add  6  to both sides of the equation :  

                     x = 6

Answer: 0.701

Step-by-step explanation:

Formula :  [tex]EBM =z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}[/tex] , where [tex]\alpha=[/tex] significance level , [tex]\sigma =[/tex] Population standard deviation, n= sample size.

As per given,  n= 22

Critical z- value for 90% confidence level : [tex]z_{\alpha/2}=1.645[/tex]

Then,

 [tex]EBM =(1.645)\dfrac{2}{\sqrt{22}}\\\\=(1.645)\dfrac{2}{4.690416}\\\\\approx0.701[/tex]

Hence ,  error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701

Answer: C

Step-by-step explanation:

For this problem, we need to translate each point by 4 units left and 3 units down.

Point A

When we move 4 units to the left, x=1. When we move 3 units down, we get y=-2. Therefore, A' is (1,-2).

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

Point B

When we move 4 units to the left, x=3. When we move 3 units down, we get y=2. Therefore, B' is (3,2).

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

Point C

When we move 4 units to the left, x=0. When we move 3 units down, we get y=2. Therefore, C' is (0,2).

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

Point D

When we move 4 units to the left, x=-2. When we move 3 units down, we get y=0. Therefore, D' is (-2,0).

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

After translating each point, we know that C is the correct answer.
