The diagonals of a rhombus intersect at the point (0,4). If one endpoint of the longer diagonal is located at point (4,10), wher
Wewaii [24]

Answer:

The other endpoint is located at (-4,-2)

Step-by-step explanation:

we know that

The diagonals of a rhombus bisect each other

That means-----> The diagonals of a rhombus intersect at the midpoint of each diagonal

so

The point (0,4) is the midpoint of the two diagonals

The formula to calculate the midpoint between two points is equal to

M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

we have

M=(0,4)

(x_1,y_1)=(4,10)

substitute

(0,4)=(\frac{4+x_2}{2},\frac{10+y_2}{2})

<em>Find the x-coordinate x_2 of the other endpoint</em>

0=\frac{4+x_2}{2}

x_2=-4

<em>Find the y-coordinate y_2 of the other endpoint</em>

4=\frac{10+y_2}{2}

8=10+y_2

y_2=-2

therefore

The other endpoint is located at (-4,-2)

Suppose a computer chip manufacturer rejects 2% of the chips produced because they fail presale testing. a) What’s the probabili
Bess [88]

Answer:

a) 0.0184

b) 0.1829

Step-by-step explanation:

a) With geometric distribution you can measure the number of trials until the first success, that is, a defective chip is found, as follows:

P(x = k) = p*(1-p)^(k-1)

This means: probability to find exactly 1 defective in k trials, p is the probability to find a defective chip, which is equal to 0.02, and the number of trials are k = 5. Replacing:

P(x = 5) = 0.02*(1-0.02)^(5-1) = 0.0184

b) If you want the probability of 1 success within k trials, compute:

P(x

Replacing with k = 10

P(x

Solve 8x + c = k for x
mr Goodwill [35]
Ok so this is how you do it.....
You need to get x by itself.
8x + c = k
Subtract c.
8x = k - c
Divide 8 from both sides.
x = k - c / 8
I hope this helps love! :)
