Question 24 (1 point)

KATRIN_1 [288]

Answer:

$A_{(x)}$ = 150 - 25x

Step-by-step explanation:

Let Leanne uses gas for x weeks.

Since expenditure on gas for one week = $25.00

Therefore, Leanne will spend on gas for x weeks = $25x

It is given in the question that she has total amount = $150.00

So the amount Leanne is left with after x weeks = 150 - 25x

If we represent amount left, by $A_{(x)}$

so the recursive formula will be

$A_{(x)}$ = 150 - 25x

Now for x = 1 week

$A_{(1)}$ = 150 - 25 = $125

Therefore, Leanne will have $125 in her gas card after the first week.

The amounts of nicotine in a certain brand of cigarette are normally distributed with a mean of 0.966 grams and a standard devia

Vesna [10]

Answer:

The probability is $P(X \le 0.305 ) = 0.01795$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu = 0.966 \ grams$

The standard deviation is $\sigma = 0.315 \ grams$

Given that the amounts of nicotine in a certain brand of cigarette are normally distributed

Then the probability of randomly selecting a cigarette with 0.305 grams of nicotine or less is mathematically represented as

$P(X \le 0.305 ) = 1 - P(X > 0.305) = 1 - P(\frac{X - \mu }{\sigma } > \frac{0.305 - \mu }{\sigma } )$

Generally

$\frac{X - \mu }{\sigma } = Z (The \ standardized \ value \ of X )$

$P(X \le 0.305 ) = 1 - P(X > 0.305) = 1 - P(Z > \frac{0.305 - 0.966 }{0.315} )$

$P(X \le 0.305 ) = 1 - P(X > 0.305) = 1 - P(Z >-2.0984 )$

From the z-table(reference calculator dot net ) value of $P(Z >-2.0984 ) =0.98205$

$P(X \le 0.305 ) = 1 - P(X > 0.305) = 1 - 0.98205$

=> $P(X \le 0.305 ) = 1 - P(X > 0.305) = 0.01795$

=> $P(X \le 0.305 ) = 0.01795$
