15minutes / 2miles = 7.5 minutes to run a single mile.

7.5minutes * 5miles = 37.5minutes

QveST [7]

Complete Question

A measurement template with a historical value of 25.500 mm is measured 27 times and a mean value of 25.301 mm is recorded. What is the percent bias when the tolerance is +/- 0.3?

Answer:

The percent bias is $B = 33.167 \%$

Step-by-step explanation:

From the question we are told that

The historical value is $S = 25.00 \ mm$

The number of times it is measured is n = 7

The mean value is $\= x = \frac{\sum x_i }{n} = 25.301 \ mm$

The tolerance is $t =\pm 0.3 = 0.3 - (-0.3) = 0.6$

Generally the percent bias is mathematically represented as

$B = 100 * \frac{\= x - \tau }{ t}$

=> $B = 100 * \frac{25.301 - 25.5000 }{0.6}$

=> $B = 33.167 \%$

The manager of a fashionable restaurant open Wednesday through Saturday says that the restaurant does about 29 percent of its bu

RideAnS [48]

Answer: The seasonal relatives is calculated are as follows:

Step-by-step explanation:

Given that,

restaurant only open from Wednesday to Saturday,

29 percent of its business on Friday
31 percent on Saturday night
21 percent on Thursday night.

∴ The remaining 19% of its business he does on Wednesday

Now, suppose that total production of sales in a given week be 'y'

So, average sales in a week = $\frac{y}{4}$

If we assume that y = 1

hence, average sales in a week = $\frac{1}{4}$

= 0.25

Now, we have to calculate the seasonal relatives,

that is,

= $\frac{Sales in a given day}{average sales in a week}$

Wednesday:

= $\frac{0.19}{0.25}$

= 0.76

Thursday:

= $\frac{0.21}{0.25}$

= 0.84

Friday:

= $\frac{0.29}{0.25}$

= 1.16

Saturday:

= $\frac{0.31}{0.25}$

= 1.24

At the movie theatre, child admission is $5.20 and adult admission is $8.60. On Sunday, 132 tickets were sold for a total sales

xxMikexx [17]

Answer:

60 tickets for children were sold

Step-by-step explanation:

Let x be the number of sold children's tickets and let y be the number of adult tickets sold, then we can pose the following equations.

$x + y = 132$ (i) Because 132 tickets were sold in total

$5.20x + 8.60y = 931.20$ (ii) because the total of $ obtained by sales was 931.20.

We must clear x. Then we substitute (i) in (ii)

$5.20x +8.60(132-x) = 931.20$

$5.20x + 1135.2 - 8.60x = 931.20$

$-3.4x = -204$

$x = 60$

60 tickets for children were sold

Charlie paid 660 for 6 shirts and four belts. One shirt costs three times as much as one belt. If Sam bought 5 shirts and 2 suck

Cerrena [4.2K]

Sam would have to pay $510 to buy 5 shirts and 2 suck belts.

Step-by-step explanation:

Let,

Cost of one shirt = x

Cost of one belt = y

According to given statement;

6x+4y = 660 Eqn 1

x = 3y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$6(3y)+4y=660\\18y+4y=660\\22y=660$

Dividing both sides by 22

$\frac{22y}{22}=\frac{660}{22}\\y=30$

Putting y=30 in Eqn 2

$x=3(30)\\x=90$

One shirt costs $90 and one belt cost $30.

Price of 5 shirts = 90*5 = $450

Price of 2 belts = 30*2 = $60

Total = 450+60 = $510

Sam would have to pay $510 to buy 5 shirts and 2 suck belts.
