PLEASE HELP WILL GIVE FULL PONITS! 3. Using the known angle, what side is known? What side is unknown? Use opposite, adjacent, o
Artyom0805 [142]

Answer:

The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.

Step-by-step explanation:

You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x

=> x = 50 m / tan(86°)

x = 50 m / 14.30 = 0.98 m

Which statement is true about the parts of this expression?
Ipatiy [6.2K]

7.5y - z/9 + 50 + 2y

Okay, so it would be best to organize and simplify this expression: 9.5y -z/9 + 50

Alright, now let's eliminate some answers.

True or false: The constant is 7.5. This is <em>false. </em>7.5 is a coefficient, 50 is a constant.

True or false: The coefficients are 7.5 and -9. This is <em>false. </em>Sure, 7.5 is a coefficient, but -9 is not. Actually, z/9 is also equal to (1/9)z, so <em>technically </em>1/9 is the coefficient.

True or false: The variables are x and y. This is <em>false. </em>Where is x? Nonexistent.

True or false: The like terms are 7.5y and 2y. This is <em>true. </em>When we simplified the equation, we first combined like terms. 7.5y and 2y are like terms and therefore able to be combined. That's how we got 9.5y.

The answer, I believe, is D. Hope this helps!

Which rule states that when two outcomes are independent, the probability that these outcomes occur together is the product of t
charle [14.2K]

The rule which states that when two outcomes are independent, the probability that these outcomes occur together is the product of their individual probabilities is "Multiplicative rule".

<h3>What is Multiplicative rule?</h3>

The likelihood of both events A and B occurring, in accordance with the probability multiplication rule, is equal to the product of the probability of B occurring and the conditional probability of event A occurring given that event B occurs.

If A and B are dependent events, then the probability of both events occurring simultaneously is given by:

P(A \cap B)=P(B) \cdot P(A \mid B)

The likelihood of both events occurring simultaneously in an experiment where A and B are two independent events is given by:

P(A \cap B)=P(A) \cdot P(B)

Multiplication Theorem of Probability:

The multiplication guidelines that we use in probability have already been taught to us, including;

\begin{aligned}&P(A \cap B)=P(A) \times P(B \mid A) \text {; if } P(A) \neq 0 \\&P(A \cap B)=P(B) \times P(A \mid B) \text {; if } P(B) \neq 0\end{aligned}

Therefore, the relationship between two events is explained by the probability multiplication rule.

Set AB represents the events in which both events A and B have occurred for two events A and B related to a sample space S.

Consequently, (AB) indicates that occurrences A and B happened at the same time. You can write the event AB as AB.

Using the characteristics of conditional probability, the likelihood of event AB is calculated.
