Write an absolute value inequality that has 3 and -5 as two of its solutions

tino4ka555 [31]

Absolute value makes all things inside positive (make result positive)
so one example is
|x+1|=4
so if you had 3 in it woul dyhave
|3+1|=4
|4|=4
4=4
true

if -5
|-5+1|=4
|-4|=4
4=4

The distribution of the amount of money spent by first-time gamblers at a major casino in las vegas is approximately normal in s

Lostsunrise [7]

Solution: We are given:

$\mu=600, \sigma =120$

We need to find the z value corresponding to probability 0.84, in order to find the how much money almost 84% of gamblers spent at casino.

Using the standard normal table, we have:

$z(0.85) = 0.9945$

Now we will use the z score formula to find the required amount:

$z=\frac{x-\mu}{\sigma}$

$0.9945=\frac{x-600}{120}$

$0.9945 \times 120 = x - 600$

$119.34 = x - 600$

$x = 600 + 119.34$

$x = 719.34$

$x = 720$ approximately

Therefore, almost 84% of gamblers spent more than $720 amount of money at this casino.

Given that the prime factorisation of 198 is 2x(3×3)x11. State the minimum integer value of

mylen [45]

Answer:

22

Step-by-step explanation:

198 = 2×3²×11

For 198n to be a perfect square, each prime factor must have an even exponent. So the smallest 198n would be:

198n = 2²×3²×11²

198n = 4356

n = 22
