Answer:

0.44

Step-by-step explanation:

The total numbers drawn = 300

Out those 146 are odd and 154 are even.

The number 8 was drawn = 22 times

So, the number of times an even number other than 8 = 154 -22 = 132

The experimental probability = The number of favorable outcomes ÷ The number of possible outcomes.

The experimental probability of an even number other than 8 being generated = \frac{132}{300}

Simplify the above fraction to decimal, we get

= 0.44

Therefore, the answer is 0.44

Given rectangle QUAD, If DU = 5x - 4 and QP = 2x + 7, then find the length of DU.
ira [324]

Answer:

DU = 86

Step-by-step explanation:

Properties of a rectangle,

- Opposite sides are equal in measure.

- Diagonals of a rectangle are equal.

- Diagonals bisect each other.

In the given rectangle QUAD,

Diagonals AQ and DU bisect each other at P.

AQ = DU

2(QP) = DU [Since, AQ = 2(PQ)]

2(2x + 7) = 5x - 4

4x + 14 = 5x - 4

5x - 4x = 14 + 4

x = 18

Since, DU = 5x - 4

DU = 5(18) - 4

     = 90 - 4

     = 86

Therefore, measure of DU = 86 units

What is the parameter of a rectangle with width 10 inches and length 13 inches
svetoff [14.1K]
The parameter of a rectangle can be alculated using the following rule:
parameter = 2(length + width)

from the givens:
length = 13 inches
width = 10 inches

so, just substitute with the givens in the equation to calculate the parameter:
parameter = 2(10+13) = 2*23 = 46 inches
