Answer:  The customer will pay $17.35 for the shirt.

Step-by-step explanation:  Given that a shirt costs $19.85 and a customer has a coupon that will save her $2.50 on the price of the shirt.

We are to find the amount that the customer will pay for the shirt.

Given that

the original cost of the shirt = $19.85

and

the price that the customer save by using coupon = $2.50.

Therefore, the total cost that the customer will pay for the shirt is given by

\$19.85-\$2.50=\$17.35.

Thus, the customer will pay $17.35 for the shirt.

A company manufacturing oil seals wants to establish X and R control charts on the process. There are 25 preliminary samples of
alisha [4.7K]

Answer:

A ) i) X control chart : upper limit = 50.475, lower limit = 49.825

    ii) R control chart : upper limit =  1.191, lower limit = 0

Step-by-step explanation:

A) Finding the control limits

grand sample mean = 1253.75 / 25 = 50.15

mean range = 14.08 / 25 = 0.5632

Based on  X control CHART

The upper control limit ( UCL ) =

grand sample mean + A2* mean range ) = 50.15 + 0.577(0.5632) = 50.475

The lower control limit (LCL)=

grand sample mean - A2 *  mean range = 50.15 - 0.577(0.5632) = 49.825

Based on  R control charts

The upper limit = D4 * mean range = 2.114 * 0.5632 = 1.191

The lower control limit = D3 * mean range = 0 * 0.5632 = 0  

B) estimate the process mean and standard deviation

estimated process mean = 50.15 = grand sample mean

standard deviation = mean range / d2  = 0.5632 / 2.326 = 0.2421

note d2 is obtained from control table

If cosine theta almost-equals 0.3090, which of the following represents approximate values of sine theta and tangent theta, for
Zepler [3.9K]

Answer:

\sin \theta = 0.9511 and \tan \theta = 3.078

Step-by-step explanation:

Given that, \cos \theta = 0.309.

Now, we have to calculate the values of \sin \theta and \tan \theta.

We know the identity that, \sin^{2}\theta + \cos^{2}\theta  = 1

So, \sin \theta = \sqrt{1 + \cos^{2}\theta} = \sqrt{1 - (0.309)^{2}} = 0.9511 {Since 0 \leq  \theta \leq  90^{\circ}}

Now, \sec \theta = \frac{1}{\cos\theta} = \frac{1}{0.309} = 3.236

Then, we know the identity, \sec^{2}\theta - \tan^{2}\theta  = 1

So, \tan \theta = \sqrt{\sec^{2}\theta - 1} = \sqrt{(3.236)^{2} - 1} = 3.078 (Answer) {Since 0 \leq  \theta \leq  90^{\circ}}
