enyata [817]
2|x-6|+14=38
\rightarrow2|x-6|=24
\rightarrow|x-6|=12

There are two cases:
1. x-6=12\rightarrow x=18
2. x-6=-12\rightarrow x=-6

So the minimum temperature is -6, and the maximum is 18.

What is 25% of 400 5% of 20
stiks02 [169]

Hello there!


What is 25% of 400?

\frac{25*400}{100}

= \frac{10,000}{100}

= 100

Thus,

25% of 400 is 100


What is 5% of 20?

Well, we just need to follow the previous steps.

\frac{5*20}{100}

= \frac{100}{100} = 1

Thus,

5% of 20 is 1


I hope this answer helps. Let me know if you have additional questions about the answer. As always, it is my pleasure helping student like you.

Find the indicated probability. round to three decimal places. a test consists of 10
Charra [1.4K]

To answer this problem, we use the binomial distribution formula for probability:

P (x) = [n! / (n-x)! x!] p^x q^(n-x)

Where,

n = the total number of test questions = 10

<span>x = the total number of test questions to pass =   >6</span>

p = probability of success = 0.5

q = probability of failure = 0.5

Given the formula, let us calculate for the probabilities that the student will get at least 6 correct questions by guessing.

P (6) = [10! / (4)! 6!] (0.5)^6 0.5^(4) = 0.205078

P (7) = [10! / (3)! 7!] (0.5)^7 0.5^(3) = 0.117188

P (8) = [10! / (2)! 8!] (0.5)^8 0.5^(2) = 0.043945

P (9) = [10! / (1)! 9!] (0.5)^9 0.5^(1) = 0.009766

P (10) = [10! / (0)! 10!] (0.5)^10 0.5^(0) = 0.000977

Total Probability = 0.376953 = 0.38 = 38%

<span>There is a 38% chance the student will pass.</span>
