dolphi86 [110]
The slope of cd is 2/5
 
 the slope of ef is -4-y/10

the lines are parallel so the slopes are equal

-4-y/10= 2/5

 -4-y=2/5x10=4
 
 -y=4=4=8 

y=-8

Suppose Wal-Mart stock is selling at $59 a share and Mattel stock is selling at $28 a share. Amy has a maximum of $6000 to inves
Ulleksa [173]

Answer:

88 shares of Wall-Mart stock,

a) Step-by-step explanation,  22 shares of Mattel stock. b) $192

Given:

Suppose Wall-Mart stock is selling at $59 a share and Mattel stock is selling at $28 a share.

Amy has a maximum of $6000 to invest.

She wishes to purchase four times as many shares of Wall-Mart as of Mattel.

Only whole shares of stock can be purchased.

Question asked:

a) How many shares of each will she purchase?

b) How much money will be left over?

Solution:

Selling price of each share of Wall-Mart stock = $59

Selling price of each share of  Mattel stock = $28

Let number of shares of Mattel stock purchased = x

Then, number of shares of Wall-Mart stock = 4x

Total money invested =$6000

<u>Shares of Mattel stock </u>\times<u> $28 + Shares of  Wall-Mart stock </u>\times<u> $59 = $6000</u>

28\times x+59\times4x=6000\\28x+236x=6000\\264x=6000

Dividing both sides by 264

x=22\frac{192}{264}

<em>That means, total 22 shares of Mattel stock is purchased and 192 is the money left over:-</em>

Number of shares of Wall-Mart stock = 4x = 4\times22=88

Total amount spent on Mattel stock shares = 22 \times $28 = $616

Total amount spent on Wall-mart stock shares = 88 \times $59 = $5192

Total amount spent on both shares = $616 + $5192 = $5808

Money left over = $6000 -  $5808 = $192

a) He will purchase 88 shares of Wall-Mart stock and 22 shares of Mattel stock.

b) Money left over is $192.

A manufacturer produces a commodity where the length of the commodity has approximately normal distribution with a mean of 6.5 i
zavuch27 [327]

The probablity that the sample's mean length is greate than 6.3 inches is0.8446.

Given mean of 6.5 inches,standard deviation of 0.5 inches and sample size of 46.

We have to calculate the probability that the sample's mean length is greater than 6.3 inches is 0.8446.

Probability is the likeliness of happening an event. It lies between 0 and 1.

Probability is the number of items divided by the total number of items.

We have to use z statistic in this question because the sample size is greater than 30.

μ=6.5

σ=0.5

n=46

z=X-μ/σ

where μ is mean and

σ is standard deviation.

First we have to find the p value from 6.3 to 6.5 and then we have to add 0.5 to it to find the required probability.

z=6.3-6.5/0.5

=-0.2/0.5

=-0.4

p value from z table is 0.3446

Probability that the mean length is greater than 6.3inches is 0.3446+0.5=0.8446.

Hence the probability that the mean length is greater than 6.3 inches is 0.8446.
