Answer:
$3.34
Step-by-step explanation:
$1.39 x 2.4 = $3.336
Answer:
x = y + v/b
Step-by-step explanation:
You can solve for x by adding v/b to both sides since that is what will isolate x the quickest and that is what you want to do when you need to solve for something.
By adding v/b to both sides, you will end up with x=y+v/b and that’s your answer!
Hope this helps!

Answer:
Option A. 56
Step-by-step explanation:
From the question given above, the following data were obtained:
Total number (n) = 8
Item taken for permutation (r) = 2
Pemutation (P) =?
ₙPᵣ = n! / (n – r)!
₈P₂ = 8! / (8 – 2)!
₈P₂ = 8! / 6!
₈P₂ = 8 × 7 × 6! / 6!
₈P₂ = 8 × 7
₈P₂ = 56
Answer: b. Her weight is 1.5 standard deviations below average.
Step-by-step explanation:
Given : A woman is told her weight has a standard score (z-score) of -1.5.
Let x denotes a random variable that represents the weight of woman.
Since , ![z=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
, where
= Population mean and
= Population standard deviation.
Put z= -1.5 in this , we get
![-1.5=\dfrac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=-1.5%3D%5Cdfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
i.e. ![-1.5\sigma=x-\mu](https://tex.z-dn.net/?f=-1.5%5Csigma%3Dx-%5Cmu)
i.e. ![x=\mu-1.5\sigma](https://tex.z-dn.net/?f=x%3D%5Cmu-1.5%5Csigma)
It means , x is 1.5 standard deviations below the mean value.
This means that: Her weight is 1.5 standard deviations below average.
Hence, the correct answer is b. Her weight is 1.5 standard deviations below average.
