Answer:

The probability that the card will be a heart or a face card is P=0.4231.

Step-by-step explanation:

We have a standard deck of 52 cards.

In this deck, we have 13 cards that are a heart.

We also have a total of 12 face cards (4 per each suit). So there are 3 face cards that are also a heart.

To calculate the probability that a card be a heart or a face card, we sum the probability of a card being a heart and the probability of it being a face card, and substract the probability of being a heart AND a face card.

We can express that as:

P(H\,or\,F)=P(H)+P(F)-P(H\&F)\\\\P(H\,or\,F)=13/52+12/52-3/52=22/52=0.4231

Hello! Hmm. Let’s see. I think it has to be 100x + 60y <= 600. The x variable represents the fast machine suits and the y variable represents the slow machine wet suits. You wrote the greater than or equal to sign, which is not correct. The maximum means no more than, which would mean the less than or equal to sign. The sign you wrote would mean at least that amount or more.

Graph the relation shown in the table. Is the relation a function? Why or why not?
patriot [66]

Answer:

The chosen topic is not meant for use with this type of problem. Try the examples below.

x + 6 y = 5

6 x + 2 y = 8

x − y + 4 = 8

Use the given functions to set up and simplify

− 1 =

2 =

0 − 4 = − 4

4 = − 4

2 = − 4

Step-by-step explanation:

Find the equation with a point and y-intercept.

y = ( y/ x  −  y )  x  +  x y

The chosen topic is not meant for use with this type of problem. Try the examples below.

Determine whether the variable is qualitative or quantitative. Explain your reasoning. The price of a new computer.
Levart [38]

Answer:

The price of a new computer is quantitative.

Step-by-step explanation:

A variable can be classified as qualitative or quantitative.

Qualitative:

When the possible values of the variables are labels, for example, good or bad, yes or no,...

Quantitative:

When the possible values of the variables are numbers, for example 1, 2, 1000,....

In this question:

The price of a computer is a numeric value, so it is a quantitative variable.

solve image :) What is the equation of the line that has a slope of 3 and passes through the point (-4, 1)?
Lesechka [4]

Answer:

<em>C.  y = 3x + 13.</em>

Step-by-step explanation:

The point slope form of a line is

y - y1 = m(x - x1)  where m = the slope,  and (x1, y1) is a point on the line.

So, substituting:

y - 1 = 3(x - -4)

y - 1 = 3(x + 4)

y = 3x + 12 + 1

y = 3x + 13.
