The cost for manufacturing the given number of cards is as follows:

(a) for 100 cards, C = $325

(b) for 150 cards, C = $425

(c) for 200 cards, C = $525

(d) for 335 cards, C = $795

<h3>How are the cost and number of cards related by an expression?</h3>

It is given that, C is the cost in dollars and n is the number of cards.

The cost and the number of cards are related by

C = 125 + n + n

<h3>Calculation:</h3>

The given expression for cost is C = 125 + n + n

(a) For making 100 cards:

n = 100;

Cost C = 125 + 100 + 100 = $325

Thus, the cost for 100 cards is $325.

(b) For making 150 cards:

n = 150;

Cost C = 125 + 150 + 150 = $425

Thus, the cost for 150 cards is $425.

(c) For making 200 cards:

n = 200;

Cost C = 125 + 200 + 200 = $525

Thus, the cost for 200 cards is $525.

(d) For making 335 cards:

n = 335;

Cost C = 125 + 335 + 335

Thus, the cost for 335 cards is $795.

Whitepunk [10]

Answer:

or,x2-x=6

or,x2-x-6=0

or,x2-3x+2x-6=0

or,x(x-3)+2(x-3)=0

or,(x-3)(x+2)=0

so either x=3

Find the a. MEAN and b. STANDARD DEVIATION for the data set. Round to two decimal places.
Dafna11 [192]

Answer:

Explained below.

Step-by-step explanation:

(10)

The data set is:

S = {124, 94, 129, 109, 114}

The mean and standard deviation are:

\bar x=\frac{1}{n}\sum x=\frac{1}{5}\times [124+94+...+114]=114\\\\s=\sqrt{\frac{1}{n-1}\sum ( x-\bar x)^{2}}

  =\sqrt{\frac{1}{5-1}\times [(124-114)^{2}+(94-114)^{2}+...+(114-114)^{2}]}\\=\sqrt{\frac{750}{4}}\\=13.6931\\\approx 13.69

The correct option is B.

(11)

According to the Empirical 95% of the data for a Normal distribution are within 2 standard deviations of the mean.

So, the adult male's height is in the same range as about 95% of the other adult males whose heights were measured.

The correct option is B.

(12)

Let the score be <em>X</em>.

Given:

μ = 100

σ = 26

X=\mu-2\sigma

    =100-(2\times 26)\\=100-52\\=48

The correct option is B.

(13)

Let <em>X</em> be the prices of a certain model of new homes.

Given: X\sim  N(150000, 2300^{2})

Compute the percentage of buyers who paid between $147,700 and $152,300 as follows:

P(147700

                                         =P(-1                                        

According to the 68-95-99.7, 68% of the data for a Normal distribution are within 1 standard deviations of the mean.

The correct option is D.

(14)

Compute the percentage of buyers who paid more than $154,800 as follows:

P(X>154800)=P(\frac{X-\mu}{\sigma}>\frac{154800-150000}{2400})

                                         =P(Z>2)\\=0.975\\

According to the 68-95-99.7, 95% of the data for a Normal distribution are within 2 standard deviations of the mean. Then the percentage of data above 2 standard deviations of the mean will be 97.5% and below 2 standard deviations of the mean will be 2.5%.

The correct option is D.

(15)

The <em>z</em>-score is given as follows:

z=\frac{x-\mu}{\sigma}
