Of the 74 people who answered "yes" to a question, 15 were male. Of the 71 people that answered "no" to the question, 6 were mal

san4es73 [151]

Answer:

55.2%

Step-by-step explanation:

We have that 74 people answered yes and 71 answered no. So the total number of people who answered the question was 74 + 71 = 145.

Now, of those 145, 74 answering yes, then the probability of saying yes is:

P (Y) = 74/145

We know that 21 (15 + 6) are men, therefore the probability of being a man is:

P (M) = 21/145

Finally, we also know how many people answering that yes, they are men, they are 15, therefore the probability is:

P (Y and M) = 15/145

Finally, we use the "sieve" formula, for the probability that he is a man or that he answered yes.

P (Y or M) = P (Y) + P (M) - P (Y and M)

Replacing we have:

P (Y or M) = 74/145 + 21/145 - 15/145

P (Y or M) = 80/145

P (Y or M) = 0.552

In other words, the probability is 55.2%

Select TWO possible values for x in the equation x2=45.

kirill [66]

Answer:

$3 \sqrt 5}$ and $-3 \sqrt 5}$

Step-by-step explanation:

Given

$x^2 = 45$

Required

Determine the values of x

$x^2 = 45$

Take square root of both sides

$\sqrt{x^2} = \±\sqrt{45}$

$x = \±\sqrt{45}$

Expand 45 as 9 * 5

$x = \±\sqrt{9 * 5}$

Split the square root

$x = \±(\sqrt{9} *\sqrt 5}$

$x = \±3 *\sqrt 5}$

$x = \±3 \sqrt 5}$

This can be further split to:

$x = 3 \sqrt 5}$ or $x = -3 \sqrt 5}$

Hence, the possible values of x are

$3 \sqrt 5}$ and $-3 \sqrt 5}$

<u>Solution-</u>

Properties of Correlation Coefficient,

1- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

2- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

As in this graph x increases y gets decreased, so it is a negative co-relation. And the points are scattered more the line, so it is a moderate negative co-relation graph. (Please follow the attached picture herewith)

What are the solutions of x^2=8-5x?

Aleksandr [31]

Answer:

x = (-5 ± √57) / 2

Step-by-step explanation:

x² = 8 − 5x

x² + 5x − 8 = 0

Solve with quadratic formula:

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -5 ± √(25 − 4(1)(-8)) ] / 2

x = (-5 ± √57) / 2
