Answer:

y = 2x/3 + 2/3

Step-by-step explanation:

1. Find the slope of the given line.

y = mx + b

6x + 7y = 3y -3

4y = -6x - 3

y = (-6x-3)/4 = -3x/2 - 3/4

The slope of y = -3/2

The slope of a line perpendicular to the line of 6x + 7y = 3y -3 would be the negative reciprocal of the slope so the slope of the line perpendicular would be -1/(-3/2) = 2/3

The equation would be:

y = 2x/3 + b

Since b is unknown, but a point is known, we plug in x and y values.

-8 = 2*(-13)/3 + b

Then solve for b:

b = 2/3

Answer:

5

Step-by-step explanation:

3 + 2 = 5

Answer:

5

Step-by-step explanation:

Answer:

If we assume 'x' an odd number let's say 1, then the other two consecutive odd integers are 1+2 and 1+4,

So assume the three consecutive odd integers be x, x+2 and x+4.

It's obvious that x is the smallest and x+4 is the largest.

Therefore 3x=9+2(x+4)

Solving for x: we get x = 17.

Hence, the three consecutive odd no. are 17, 19, 21

difference of x-coordinates = 4-(-3) = 7

difference of y-coordinates = 0-(-2)  = 2

length of MN = √(7²+2²) = √53 ≅ 7.28 units

tanθ = 2/7

θ = arctan(2/7) ≅ 15.9°

heading = 74.1° from north

The magnitude and direction of points M(-3, -2) and N(4, 0) is 7.28 units and 74.1 degrees

We have:

M(-3, -2) and N(4, 0)

Calculate the magnitude using

[tex]MN =\sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2[/tex]

This gives

[tex]MN =\sqrt{(4 + 3)^2 +(0 + 2)^2[/tex]

Evaluate

MN = 7.28

The direction is calculated as:

[tex]\theta = 90 - \tan^{-1}(\frac{y_2 - y_1}{x_2 -x_1})[/tex]

This gives

[tex]\theta = 90 -\tan^{-1}(\frac{0+2}{4+3})[/tex]

[tex]\theta =90 - \tan^{-1}(\frac27)[/tex]

Take the arc tan

[tex]\theta = 90 - 15.9\°[/tex]

Evaluate

[tex]\theta = 74.1\°[/tex]

Hence, the magnitude and direction of points M(-3, -2) and N(4, 0) is 7.28 units and 74.1 degrees

Answer:

0.6864 = 68.64% probability out of the 8 new cars it just received that, when each is tested, no more than 2 of the cars have defective radios

Step-by-step explanation:

The cars are chosen without replacement, so the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

48 new cars being shipped to local dealerships, corporate reports indicate that 12 have defective radios installed.

This means that [tex]N = 48, k = 12[/tex]

8 cars received.

This means that [tex]n = 8[/tex]

What is the probability out of the 8 new cars it just received that, when each is tested, no more than 2 of the cars have defective radios

This is

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

In which

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,48,8,12) = \frac{C_{12,0}*C_{36,8}}{C_{48,8}} = 0.0802[/tex]

[tex]P(X = 1) = h(1,48,8,12) = \frac{C_{12,1}*C_{36,7}}{C_{48,8}} = 0.2655[/tex]

[tex]P(X = 2) = h(2,48,8,12) = \frac{C_{12,2}*C_{36,6}}{C_{48,8}} = 0.3407[/tex]

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0802 + 0.2655 + 0.3407 = 0.6864[/tex]

0.6864 = 68.64% probability out of the 8 new cars it just received that, when each is tested, no more than 2 of the cars have defective radios

Answer:

if I am not mistaken.. the median would be 9 and the the mean is also 9.

Step-by-step explanation:

first you order the numbers from least to greatest and the find with is the middle number to find the median.

6,7,8,8,8,9,10,12,13 (answer: 9)

To find the mean you will add all of the numbers up and then divide that number by the amount of numbers there are.

1) 6+7+8+8+8+9+10+12+13= 81

2) 81 ÷ 9 =9

Answer:

Mean: 9, Median: 8 Mode: 8

Step-by-step explanation:

MEAN:   The AVERAGE total of all the values divided by the numbers of values.

6 + 7+ 8 + 8 + 8 + 9 + 10 + 12 + 13 = 81        81/9 (set of #'s)= 9

MEDIAN:  The number in the MIDDLE of the list of values.

6, 7, 8, 8, 8, 9, 10, 12, 13         So, the middle value is 8

MODE:   The number that appears the most.

6, 7, 8, 8, 8, 9, 10, 12, 13         So, 8 appears 3 times.

Step-by-step explanation:

This question is incomplete, the complete question is;

Suppose u and v are functions of x that are differentiable at x=0

and that { u(0) = 7, u'(0) = -5 }  { v(0)= -1, v'(0) = -4 }

Find the values of the following derivatives at x = 0.

a) [tex]\frac{d}{dx}[/tex]( uv )

b)  [tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )

c)  [tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )

Answer:

a) [tex]\frac{d}{dx}[/tex]( uv ) = -23  

b) [tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )  = 33

c) [tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] ) = -32/49 or - 0.6531

Step-by-step explanation:

Given that;

{ u(0) = 7, u'(0) = -5 }  { v(0)= -1, v'(0) = -4 }

a)

[tex]\frac{d}{dx}[/tex]( uv )

we differentiate

[tex]\frac{d}{dx}[/tex]( uv )  = uv' + vu'

at x = (0), we substitute our values

[tex]\frac{d}{dx}[/tex]( uv ) = ( 7 × -4 ) + ( -1 × -5)

[tex]\frac{d}{dx}[/tex]( uv )  = -28 + 5

[tex]\frac{d}{dx}[/tex]( uv ) = -23  

b)

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )

we differentiate

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] ) = ( vu' - uv' ) / v²

at x=0, we substitute our values

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] ) = ( (-1 × -5) - (7 × -4 ) ) / (-1)²

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] ) = (( 5 - ( -28 )) / 1

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )  = 33 / 1

[tex]\frac{d}{dx}[/tex]( [tex]\frac{u}{v}[/tex] )  = 33

c) [tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )

we differentiate

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = ( uv' - vu' ) / u²

at x=0, we substitute our values

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = ( (7 × -4) - (-1 × -4) ) / (7)²

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] ) = ( -28 - ( 4 ) ) / 49

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = ( -28 - 4 ) /49

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] )  = -32 / 49

[tex]\frac{d}{dx}[/tex]( [tex]\frac{v}{u}[/tex] ) = -32/49 or - 0.6531

Answer:
