She used the wrong formula it should be length times width times height
The correct work would be 6 times 5 times 1.2 which would equal 36 I worked through the problem on my own and followed the steps that they followed to find the error

Answer:

1: she used the wrong formula

2: 36cubic feet

3: the strategy: knowing that to find the volume of a rectagle is l*w*h and subtituting in the correct numbers

Step-by-step explanation:

1: to find the volume of a rectangle is height*width*length

2: you multiply 6*5*1.2 and you should get 36 and sice you are finding volume it is cubic and the measurment

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

frutty [35]

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:

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

Then, the probability of having one or more dead batteries in the sample (k≥1) is:

$P(x\geq1)=1-P(x=0)\\\\\\P(x=0) = \dbinom{4}{0} p^{0}q^{4}=1*1*0.7^4=0.2401\\\\\\P(x\geq1)=1-0.2401=0.7599\approx0.76$

What is the distance between P(-3,-25) and Q(50,-2)

Karolina [17]

$Dist = (x2-x1)^{2} + (y2-y1)^{2}$

above is the distance formula, plugging your numbers from P(x1,y1) and Q(x2,y2).

$Dist = \sqrt{(50-(-3))^{2} + (-2-(-25))^{2} }$
or $\sqrt{ 53^{2} + 23 ^{2} }$
