Answer:

Step-by-step explanation:

Pythagorean's Theorem states that a² + b² = c² for any right triangle.

7² + 24² = 25²

This statement is true, as both sides equal 625, therefore the correct answer is B.

Suppose that, for every lot of 100 computer chips a company produces, an average of 1.4 are defective. Another company buys many

Vesna [10]

Answer:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)$

And we can find the individual probabilities like this:

$P(X=0) =1.4^0 \frac{e^{-1.4}}{0!}= 0.2466$

$P(X=1) =1.4^1 \frac{e^{-1.4}}{1!}= 0.3452$

$P(X=2) =1.4^2 \frac{e^{-1.4}}{2!}= 0.2417$

$P(X=3) =1.4^3 \frac{e^{-1.4}}{3!}= 0.1128$

And replacing we got:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)=0.2466+ 0.3452+0.2417+0.1128=0.9463$

Step-by-step explanation:

Definitions and concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

$P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}$

And the parameter $\lambda=1.4$ represent the average ocurrence rate per unit of time.

Solution to the problem

For this case the batch would be rejected if we found more than 3 defects, so then the probability of accept the batch would be given by:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)$

And we can find the individual probabilities like this:

$P(X=0) =1.4^0 \frac{e^{-1.4}}{0!}= 0.2466$

$P(X=1) =1.4^1 \frac{e^{-1.4}}{1!}= 0.3452$

$P(X=2) =1.4^2 \frac{e^{-1.4}}{2!}= 0.2417$

$P(X=3) =1.4^3 \frac{e^{-1.4}}{3!}= 0.1128$

And replacing we got:

$P(X\leq 3)= P(X=0) +P(X=1)+P(X=2) +P(X=3)=0.2466+ 0.3452+0.2417+0.1128=0.9463$

A ruler 30 cm long is broken into two parts in the ratio 8:7. How long are the two parts?

Mandarinka [93]

Pro tip: always assign ratios a variable.

So 8x + 7x = 30; 15x=30; x=2

Now plug in x;
8(2)=16 and 7(2)=14
So the pieces are 16 and 14 cm which adds up to 30.

This year, Shelley paid $2,363 for season tickets to her favorite baseball team, which is 15%

algol13

Answer:

I got 2,717.45

Step-by-step explanation:

I did 2,363 × 15% = 354.45

then 2,363 + 354.45 = 2,717.45
