Commission
4,950×0.09=445.5
Total pay
445.5+100=545.5

P(s)=100+9s/100

p(s)=(10000+9s)/100

p(4950)=(10000+9(4950))/100

p(4950)=$545.50

1. A new brand of hot dog claims to have a lower sodium content than the leading brand.

kherson [118]

Answer:

(a) Population mean = 314.5mg

(b) Margin of error = 21.281mg

(c) No, 350mg is not a plausible value

The new brand of hot dog has a lower sodium content on average than the leading brand

(d) Yes

Step-by-step explanation:

(a) Population mean = (370+326+322+297+326+289+293+264+327+331)/10 = 3145/10 = 314.5mg

(b) Margin of error = t×sd/√n

sd = 29.73, n = 10, degree of freedom = n-1 = 10-1 = 9

Assuming 95% confidence level

t-value corresponding to 9 degrees of freedom and 95% confidence level is 2.262

Margin of error = 2.262×29.73/√10 = 21.281mg

(c) No

Lower limit of new brand = 314.5 - 21.281 = 293.219mg

Upper limit = 314.5 + 21.281 = 335.781mg

The range of sodium content for the new brand of hot dog is between 293.219mg and 335.781mg which is lower than the leading brand (350mg)

(d) Margin of error = t×sd/√n

From the formula above, margin of error varies inversely as the square root of sample size

The smaller the sample size (n = 10) the larger the margin of error and the less accurate is the population mean

The larger the sample size (n = 40) the smaller the margin of error and the more accurate is the population mean

7x-2=5x+14<br> X=?<br> (step by step needed)

prisoha [69]

Answer:

x = 8

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

$7x-2-5x=5x+14-5x$
$2x-2=14$

Step 2: Add 2 to both sides.

$2x-2+2=14+2$
$2x=16$

Step 3: Divide both sides by 2.

$2x/2=16/2$
$x=8$

Step 4: Check if solution is correct.

$7(8)-2=5(8)+14$
$56-2=40+14$
$54=54$

Therefore, x = 8.

Mike's car broke down 5 miles from the auto shop. If he can push his car 1,056 feet per hour, how many hours will it take him to

Alinara [238K]

Answer:

It'll take 25 hours to get to the auto shop

Step-by-step explanation:

Given

Distance = 5 miles

Speed =1056 feet per hour

Required

How long will it take to the auto shop

This can be solved using Speed's formula;

$Speed = \frac{Distance}{Time}$

Substitute values for Speed and Distance

$\frac{1056 ft}{hr} = \frac{5 miles}{Time}$

1 mile = 5280 feet;

So:

$\frac{1056 ft}{hr} = \frac{5 * 5280 ft}{Time}$

$\frac{1056 ft}{hr} = \frac{26400ft}{Time}$

Cross Multiply

$Time * 1056ft = 26400ft * hr$

Divide both sides by 1056ft

$Time * \frac{1056ft}{1056ft} = \frac{26400ft * hr}{1056ft}$

$Time = \frac{26400ft * hr}{1056ft}$

$Time = 25hr$

<em>Hence, it'll take 25 hours to get to the auto shop</em>
