What is the value of x in the equation x-3y = 30, when y = 15?<br> 1<br> 04<br> 8<br> 80<br> 200

True [87]

Answer:

x = 75

Step-by-step explanation:

Given information from the question:

x - 3y = 30

y = 15

We can substitute y = 15 into the equation to find x.

x - 3(15) = 30

x - 45 = 30

x - 45 + 45 = 30 + 45

x = 75

At an antique boat show, 90% of the boats are made of a natural, polished wood. 75% of the boats have some chrome accents on the

nadya68 [22]

Answer:

0.933 ; not independent

Step-by-step explanation:

Given :

A - made from natural polished wood

B - made from chrome accent

P(A) = 0.9

P(B) = 0.75

P(AnB) = 0.7

1.) probability of natural wood Giveb that it has chrome accent

P(A|B) = P(AnB) / P(B)

P(A|B) = 0.7 / 0.75

P(A|B) = 0.933

2.)

For an independent event :

P(AnB) = p(A) * p(B)

P(AnB) = 0.9 * 0.75 = 0.675

However, p(AnB) Given here is 0.7, thus the event aren't independent

What is the value of f(3) when f(x) = 4x + 1

valentina_108 [34]

Here is the equation:

$f(x)=4x+1$

You need to find f(3). To do that, substitute all the x's with 3:

$f(x)=4x+1 \rightarrow f(3)=4\times3 + 1$

The first thing you need to do is multiply 4 by 3. Multiply:

$4 \times 3 = 12$

Here is your new equation:

$f(3)=12+1$

To get your answer, you need to add 12 and 1. Add:

$12+1 = 13$

That means:

$\bf f(3)=13$

What is the distance between (4,2) and (-1,-3)

Sati [7]

<h2>Solving for the Distance between two Points</h2><h3>Answer:</h3>

$5 \sqrt{2}$ or $7.071$

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this Question to know more about distances between two points: <u>brainly.com/question/24629826</u></em>

Given:

$(4,2)$

$(-1,-3)$

Solving for the Distance:

$\sqrt{(4-(-1))^2 +(2 -(-3))^2} \\ \sqrt{(4 +1)^2 +(2 +3)^2} \\ \sqrt{5^2 +5^2} \\ \sqrt{25 +25} \\ \sqrt{50} \\ \sqrt{25 \cdot 2} \\ 5 \sqrt{2}$

<u>Note:</u>

$5 \sqrt{2} \approx 7.071$
