What is P(not odd)? if u roll a 6-sided die

ANEK [815]

$\qquad\qquad\huge\underline{{\sf Answer}}$

We have to find the probability of not getting odd, whole rolling a 6 sided die ~

Actually dices have 3 odd numbers (1 , 3 , 5) and 3 non - odd numbers (2 , 4 ,6)

When we roll a dice, we may get any of the six numbers, so total possible outcomes are 6

and, The number of Favorable outcomes is 3, i.e non - odd numbers.

$\qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{favourable \: outcomes}{total \: \: outcomes}$

$\qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{3}{6}$

$\qquad \sf \dashrightarrow \: p(not \: odd) = \dfrac{1}{2} \: \: \: or \: \: \: 0.5$

An equilateral triangle has sides of length(3k-2)units. A regular pentagon(5 sides) has sides of (2k+0.5)units. If the perimeter

Vitek1552 [10]

The length of side of triangle is 5 units and length of side of pentagon is 1.5 units.

SOLUTION:

Given, An equilateral triangle has sides of length $(3k-2)$ units.

Then, perimeter of the triangle will be $3 \times(3 k-2)=9 k-6$

A regular pentagon (5 sides) has sides of $(2k+0.5)$ units.

Then, perimeter of the pentagon will be $5 \times(2 k+0.5)=10 k+2.5$

We have to find the dimensions of each shape . Now, the perimeter of the triangle is twice the perimeter of the pentagon,

So, $\text {perimeter of triangle} = 2\times \text{perimeter of pentagon}$

$\begin{array}{l}{\rightarrow 9 k-6=2(10 k+2.5)} \\\\ {\rightarrow 9 k-6=20 k+5} \\\\ {\rightarrow 20 k-9 k=-6-5} \\\\ {\rightarrow 11 k=-11} \\\\ {\rightarrow k=-1}\end{array}$

Then, length of side of triangle $= 3(-1)-2 = - 5$

Length of side of pentagon $= 2(-1) + 0.5 = - 1.5$

We have to neglect, negative sign as lengths can’t be negative. Even if we change the sign above all conditions are satisfied.

A homeowner is installing a swimming pool. You have been asked to install a circuit to operate a 600-watt underwater light and a

insens350 [35]

Answer:

The answer is given below

Step-by-step explanation:

The loads in the circuit are continuous duty, so the circuit can only loaded to 80% of its current rating.

Calculate 80% current rating of the circuit breaker.

Icb = [ 80/100] (20 A)

= (O.8) (20 A )

= 16 A

Now we assume that the value of supply voltage is 120 V

Now we will calculate current flows via under water light which will be taken as Load 1

Ii = 500 W/120 V

= 4.167 A

Current via the circulating pump which will be taken as Load 2 IS 8.5 A

I = load1 + load 2

= 4.167 A + 8.5 A

= 12.67 A

The total current in the circuit obtained which is less than the circuit breaker rating current. Therefore, the power can be operated for both the loads.

Which of the following makes this statement true: x(4 + 3) = 12 + 9?

adoni [48]

Answer: B(3)

Explanation: 12+9=21 so since 4+3 only equals 7, you plug in x as 3... since 7x3 is 21 that helps make the statement true bc both equations are equal.
