Answer:

okay here we go

Step-by-step explanation:

$in \: vectos \: ab \: means \: ob - oa \\ but \: the \: midpoint \: m \: is \: equal \: to \: a \: half \: of \: ab \\ \\ therefore \: m = \frac{1}{2} ab \\ = \frac{1}{2} (ob - oa) \\ = \frac{1}{2} (ob - (3. - 6)) \\ (4. - 2) = \frac{1}{2} (ob - (3. - 6)) \\ (8. - 4) = (ob - (3. - 6)) \\ ob = (11. - 2)$

the length , breadth and height of a cuboid is 2x^2y cm,5y^2z cm and 4z^2x cm. The volume of the cuboid is ...............

kondor19780726 [428]

For this case we have that by definition, the volume of a cuboid is given by:

$V = L * A * h$

Where:

L: It's the long

A: It is the width

h: It is the height

According to the problem data we have:

$L = 2x ^ 2y \ cm\\A = 5y ^ 2z \ cm\\h = 4z ^ 2x \ cm$

So, the volume of the cuboid is:

$V = (2x ^ 2y) (5y ^ 2z) (4z ^ 2x)\\V = 10x ^ 2y ^ 3z (4z ^ 2x)\\V = 40x ^ 3y ^ 3z ^ 3$

Finally, the volume of the cuboid is: $V = 40x ^ 3y ^ 3z ^ 3$

Answer:

$V = 40x ^ 3y ^ 3z ^ 3$

REALLY NEED MATH MIDPOINT STUFF HELP

elena-14-01-66 [18.8K]

The answer to this question would be: (6.5 , 8.5)

To answer this question, you need to determine the x and y distance of both point. From A point the distance would be:
X distance= 14-4= 10
Y distance= 10-8= 2

Making it into 1:3 ratio means that dividing the line into 4 parts then take 1 part from the point A, or 3 part from point B. From A point the distance would be 1/4 total distance
The location would be:
X= 4 + (10*1/4)= 6.5
Y= 8+ (2*1/4)= 8.5
(6.5 , 8.5)

A firm buys components from two suppliers: 60 percent from supplier A and the rest from supplier B. It so happens that 9 percent

Llana [10]

Answer:

0.114,0.5263

Step-by-step explanation:

Given that a firm buys components from two suppliers:

A : 60% Defective 9%

B:40% Defective 15%

a) the probability that the next component the firm buys is defective

=prob purchased from A and defective + prob purchased from B and defective

= $0.60(0.09)+0.40(0.15)\\= 0.054+0.06\\=0.114$

b) the probability that the component that the firm buys is from supplier B if we know that it is defective

=Prob from B and defective/Prob defective

= $\frac{0.40(0.15)}{0.114} \\=0.5263$
