E=1

Another step:
2e is 2xe, so the opposite of multiplying is dividing.

You could do it another way is to take the 2 from the e and write it under the other 2 as a fraction and there’s the answer. Then you reduce it

A light bulb consumes 960 watt hours per day how long does it take to consume 4320 watt hours

VARVARA [1.3K]

Since we need to determine how long it takes for the watt hours to consume 4320 watt hours, we would need to divide.

We would simply divide.

4320/950= 4.5

The 4.5 represents how long it would take for the light bulb to consume 4320 watt hours.

Therefore, the answer would be 4.5 days.

Answer

4.5 days

Recap

1. We read the problem and determined that in order to solve the problem we would need to divide.

2. We then divided 4320/960= 4.5

3. We came to the conclusion that 4.5 days would be the answer.

What is the value of "w" ?

NISA [10]

Answer:

w = $\sqrt{147}$

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

w² + 7² = 14²

w² + 49 = 196 ( subtract 49 from both sides )

w² = 147 ( take the square root of both sides )

w = $\sqrt{147}$

Solve the system by substitution. y=6x y=3x+21 ( , )

Dimas [21]

Answer:

(7,42)

Step-by-step explanation:

Imput the 6x for the Y:

6x=3x+21

move the variable to the left

6x-3x=21

collect like terms:

3x=21

divide both sides by 3x and youll get this for X

x=7

Imput x=7 into the equation

Y=6x7

solve:

y=42

Factor completely 81x2 − 100. (1 point) (10x − 9)(10x − 9) (10x − 9)(10x + 9) (9x − 10)(9x + 10) (9x − 10)(9x − 10)

MArishka [77]

The complete factorization of the equation 81x² - 100 is; (9x - 10)(9x + 10)

<h3>How to factorize quadratic equations?</h3>

We are given the quadratic equation;

81x² - 100

Now, according to quadratic identities, we know that;

(a + b) * (a - b) = a² - b²

Now, our equation can also be expressed as;

81x² - 100 = 9²x² - 10²

Thus, applying the quadratic identity gives us;

(9x + 10)(9x - 10)

A manufacturer of televisions subjects the equipment to a comprehensive testing process for all essential functions before the t

Vikki [24]

Answer:

The value is $P(X \ge 9) = 0.9138$

Step-by-step explanation:

From the question we are told that

The probability of passing the test is $p = 0.95$

The sample size is n = 10

Generally the distribution of the comprehensive testing of equipment follows a binomial distribution

i.e

$X \~ \ \ \ B(n , p)$

and the probability distribution function for binomial distribution is

$P(X = x) = ^{n}C_x * p^x * (1- p)^{n-x}$

Here C stands for combination hence we are going to be making use of the combination function in our calculators

Generally the probability that at least 9 pass the test is mathematically represented as

$P(X \ge 9) = P(X = 9 ) + P(X = 10 )$

=> $P(X \ge 9) = [^{10}C_9 * (0.95)^9 * (1- 0.95)^{10-9}] + [^{10}C_{10} * (0.95)^{10} * (1- 0.95)^{10-10}]$

=> $P(X \ge 9) = [0.3151] + [0.5987]$

=> $P(X \ge 9) = 0.9138$
