I think the correct answer from the choices listed above is option C. If triangle abc= def by side-side-side triangle congruence theorem, then b=e by Corresponding parts of congruence. CPCTC states that if two or more triangles arecongruent, then all of their corresponding angles and sides are congruent as well.

Answer: D: Corresponding parts of congruent triangles are congruent

Step-by-step explanation:

If two triangle are congruent using postulate of theorems of congruence then their corresponding parts are congruent by CPCTC rule.

The CPCTC rule says that if two triangles are congruent then their each corresponding part whether angles or sides must be equal.

Here if triangle abc= def by side-side-side triangle congruence theorem,

then b=e [which is a corresponding part of both triangles] by Corresponding parts of congruent triangles are congruent.

Answer:

$P(X$

And we can find this probability using the normal standard table or excel:

$P(Z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the amount of ml of a population, and for this case we know the distribution for X is given by:

$X \sim N(298,3)$

Where $\mu=298$ and $\sigma=3$

We are interested on this probability

$P(X$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

If we apply this formula to our probability we got this:

$P(X$

And we can find this probability using the normal standard table or excel:

$P(Z$

The sum of three numbers is 69. The second number is 6 less than the first. The third number is 3 times the first. What are the

almond37 [142]

Answer and Step-by-step explanation:

To solve, we would set the first number to x, and make an equation.

Solve for x.

x + (x - 6) + 3x = 69.

Add and combine like terms.

2x + 3x - 6 = 69

5x - 6 = 69

Add 6 to each side of the equation.

5x = 75

Divide by 5 to both sides.

x = 15

The first number is 15.

The second number is (x - 6) = (15 - 6) = 9.

The third number is 3x = 3(15) = 45.
