Answer:

x = 1

Step-by-step explanation:

First, add 3 to both sides to isolate the variable. This leaves us with the following:

5 = 5x

Now, divide both sides by 5. This leaves us with our answer:

x = 1

A boat traveled 54 km with the stream and 42 km against the stream spending a total of as much time as it would spend while trav

Genrish500 [490]

Answer:

24 km/h

Step-by-step explanation:

The speed of the boat in the lake = x
The speed of the current = 3 km/h

<u>Required equation:</u>

54 / (x + 3) + 42 / (x - 3) = 96/x
9x(x - 3) + 7x(x + 3) = 16(x + 3)(x - 3)
9x² - 27x + 7x² + 21x = 16x² - 144
6x = 144
x = 144/6
x = 24 km/h

Drag tiles to fill in the blanks to complete the expression that could be used to predict the number of winners of a game. Tiles

ziro4ka [17]

Answer:

First blank - A)Total Number of Possible Outcomes

Second blank - B)Number of Winners

Step-by-step explanation:

The exact question is as follows :

We know that,

Probability of an event is equals to Total number of Favorable outcomes divided by Total number of outcomes

So,

P(event) = Number of favorable outcomes ÷ Total Number of Possible Outcomes

As we have to predict the Number of winners of a game

So,

P(Number of winner) = Number of winners ÷ Total number of Contestants

∴ we get

P(event) = Number of favorable outcomes ÷ Total Number of Possible Outcomes

= Number of winners ÷ Total number of Contestants

AHHHHHHHHHHHHHHH SOMEONE ANSWEER THIS PLEEASEEE NEED ANSWER ASP 20 pts!! Please answer!!! I literally don't get this ;c so PLEAS

Blababa [14]

Answer:

$P(A\textrm{ and }B)=\frac{3}{14}$

Step-by-step explanation:

Given:

$P(A)=\frac{4}{7}$

$P(B|A)=\frac{3}{8}$

We know that, conditional probability of B given that A has occurred is given as:

$P(B|A)=\frac{P(A\cap B}{P(A)}$ . Expressing this in terms of $P(A\cap B)$ , we get

$P(A\cap B)=P(B|A)\times P(A)$

Plug in the known values and solve for $P(A\cap B)$ . This gives,

$P(A\cap B)=P(B|A)\times P(A)\\P(A\cap B)=\frac{3}{8}\times \frac{4}{7}\\P(A\cap B)=\frac{12}{56}=\frac{3}{14}$

Therefore, the probability of events A and B occurring is $\frac{3}{14}$ .
