Find one of the solutions to the following absolute value equation: 26 + 4) = 48

Answer : MAYBE 18 (?)
I’m not 100% sure
Explanation: you always solve what’s is parentheses “( )” first so then you get the equation

Then ( this is the part I’m not sure about)
You subtract 30 out that means 30-30=0 & 48-30 = 18 so that’s where I found my answer but idk I haven’t done absolute value since Algebra 1 !!

A package of 10 batteries is checked to determine if there are any dead batteries. Four batteries are checked. If one or more ar

Answer:

There is a probability of 76% of not selling the package if there are actually three dead batteries in the package.

Step-by-step explanation:

With a 10-units package of batteries with 3 dead batteries, the sampling can be modeled as a binomial random variable with:

n=4 (the amount of batteries picked for the sample).
p=3/10=0.3 (the proportion of dead batteries).
k≥1 (the amount of dead batteries in the sample needed to not sell the package).

The probability of having k dead batteries in the sample is:

$P(x=k) = \dbinom{n}{k} p^{k}q^{n-k}$
