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

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

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

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

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

(5a +7b)b/(b+2b)=? 4a ,4ab , 2a+4b , 5a+7b/3 , 5a+5b

musickatia [10]

The correct answer is: [D]: " $\frac{5a + 7b}{3}$ " .
__________________________________________________
Explanation:
__________________________________________________
$\frac{b(5a + 7b)}{b +2b}$ ;

Simplify the "denominator" ; → (b + 2b = 1b + 2b = 3b) ;

and rewrite:

$\frac{b(5a + 7b)}{3b}$ ;

Cancel out the "b" in the "numerator" to a "1" ;
and cancel the "3b" in the "denominator to a "3" ;

{since: "b ÷ b = 1 "; and since: "3b ÷ b = 3" } ;

and rewrite as:
____________________________________________________
$\frac{5a + 7b}{3}$ ;
____________________________________________________

→ which is: Answer choice: [D]: " $\frac{5a + 7b}{3}$ " .
____________________________________________________

What are the solutions of 3t + 2 < 7 or -4t + 5 < 1? Graph the solutions and put each solution in interval notation.

Ghella [55]

Answer:

$\displaystyle (-∞, 2\frac{1}{3}) ∪ (1, ∞) \\ \\ 2\frac{1}{3} > t \:OR\: 1 < t$

Step-by-step explanation:

3t + 2 < 7 OR −4t + 5 < 1

- 2 - 2 - 5 - 5

___________________

$\displaystyle \frac{3t}{3} < \frac{7}{3} \:OR\: \frac{-4t}{-4} < \frac{-4}{-4} \\ \\ t < 2\frac{1}{3} \:OR\: t >1$

**Whenever you divide\multiply by a negative integer, you reverse the inequality symbol given to you initially.

As you can see in the above graph, the graph is connected ALTOGETHER. Be aware that this will not ALWAYS be the case because a majourity of these graphs are seperated, pointing in OPPOSITE directions.
