vagabundo [1.1K]

Answer:

56 days

Explanation:

$\sf Half \ Life : A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }$

where A is final amount, Ao is initial amount, t is time taken, h is half life

Here given:

initial amount: 400 millicuries

final amount: 3.125 millicuries

half life: 8 days

time taken: ?

Hence solve for time taken:

$\sf \rightarrow A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }$

insert values given

$\sf \rightarrow 3.125 = 400 \ x \ (\dfrac{1}{2} )^{\dfrac{t}{8} }$

divide both sides by 400

$\sf \rightarrow (\dfrac{1}{2})^{\dfrac{t}{8}}=0.0078125$

apply exponent rule

$\sf \rightarrow {\dfrac{t}{8}}=\dfrac{ln(0.0078125)}{ln(1/2)}$

simplify

$\rightarrow \sf \dfrac{t}{8}=7$

multiply both sides by 8

$\rightarrow \sf t = 56$

A large group of students took a test in Physics and the final grades have a mean of 70 and a standard deviation of 10. If we ca

Sholpan [36]

Answer:

The scores are between 50 and 90

Step-by-step explanation:

When we say middle 95%, we means that this value falls between 2 standard deviations of the mean i.e

μ ± 2σ

Hence,

mean of 70 and a standard deviation of 10

μ ± 2σ

μ - 2σ

70 - (2 × 10)

= 70 - 20

= 50

μ + 2σ

= 70 + (2 × 10)

= 70 + 20

= 90
