The tables below show running hours of three printers that produce greeting cards and the total number of greeting cards produce
AysviL [449]

<u>ANSWER</u>

The correct answer is A


<u>EXPLANATION</u>



To find the ink cost of each card coming from printer  B, we need to find the total cost from printer B and the total number of cards printed by Printer B.


The total hours of all the three printers over the three weeks

=40+45+55+50+50+30+45+40+60=415


The total hours of printer B only

=50+50+30=130


Total number of cards produced over the three weeks


=7950+7800+9600=25350


We can use ratio and proportion to determine the total cards produce by printer B only.


415:25350


130:x


If less, more divides


x=\frac{130\times 25350}{415} \approx7941


Total cost of Printer B in 130 hours

$=130 \times 15=1950


The ink cost

=\frac{1950}{7941}


=0.2456


$\approx 0.30

A? 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense he
masya89 [10]

Answer:

The correct option is option c.

H0: p not equal to 0.5

H1: p equal to 0.5

Step-by-step explanation:

1. H0: p not equal to 0.5

H1: p equal to 0.5

2. P cap = 104/ 260

P cap = 0.4. ( where p cap is the sample proportion)

3. Find the test statistic

Using : Z = ( p cap - p) /√ [(p ×q)/n] where p = 0.5 q= 1-p = 0.5. n=260

Z = -3.23

4. P value = 0.006

5. Since p value is less than the alpha level (0.01) . we reject the null hypothesis and conclude that the touch therapists are not effective.

Gavin agrees to buy a 6 month package deal of monthly gym passes, and in turn receives a 15% discount. Write an algebraic expres
dolphi86 [110]
15% off means 85% on so I would use .85x · 6 = total monthly cost  to represent this problem.  The dot represents times (I did not want to confuse things by using x)

Other ways to express this:

6 x .85x
6(.85x)
.85x (6)
