For what values of a the following expressions are true: |a−5|=5−a

julia-pushkina [17]

Answer:

Whenever $a\leq 5$ .

Step-by-step explanation:

We can play around with some numbers and develop some rules for this equation.

Note that the number 5 and -5 are used here, so let's try using 5 as a.

$|5-5| = 5-5\\|0| = 0\\0 = 0$

So 5 works. Let's try a random number like 3.

$|3-5| = 5-3\\|-2| = 2\\2 = 2$

Okay, with this info we know that we might be able to develop one rule that $a$ . Just to test, let's try 0, -3, and -5.

$|0-5| = 5-0\\|-5| = 5\\5 = 5$

Zero works.

$|-3 - 5| = 5-(-3)\\|-8| = 8\\8 = 8$

-3 works.

$|-5 -5| = 5-(-5)\\|-10| = 10\\10 = 10$

-5 works. Now, this might stop here making the equation $-5 \geq a \leq 5$ , so let's test a number outside of -5 - say -20.

$|-20 - 5| = 5-(-20)\\|-25| = 25\\25 = 25$

Yes! This works, so a works for this equation as long as $a \leq 5$ .

Hope this helped!

Amelia randomly selects two cards, with replacement, from a normal deck of cards. Calculate the probability that: the first card

Lena [83]

Answer:

1 / 2704

Step-by-step explanation:

Number of cards in a deck = 52

9 of clubs in a deck = 1

10 of clubs in a deck = 1

Probability = required outcome / Total possible outcomes

P(9 of club) = 1 / 52

With replacement ;

Then ;

P(10 of club) = 1 / 52

Hence,

P(9 of club, then 10 of club) = 1/52 * 1/52 = 1 / 2704

he graph shows the distribution of time (in hours) that teenagers spend playing video games per week. A graph titled Video games

Goshia [24]

"The graph shows the distribution of time (in hours) that teenagers spend playing video games per week. ", The statement that best describes the distribution is "The distribution is approximately Normal, with a mean of 14 hours and a standard deviation of 4" Option B.

This is further explained below.

<h3>What is Normal distribution?</h3>

Generally, Data closer to the mean tends to occur more often than data further from the mean, as shown by the normal distribution, also known as the Gaussian distribution. The normal distribution may be represented graphically as a "bell curve."

In conclusion, "the graph illustrates the distribution of the amount of time, in hours, that teens spend playing video games over the course of a week," The statement "The distribution is nearly normal, with a mean of 14 hours and a standard deviation of 4" is the one that gives the most accurate account of how the data was distributed.
