Answer:

a) how many would you expect to fail to meet a minimum specification limit of 35-pounds tensile strength?

7933 parts

b) How many would have a tensile strength in excess of 48 pounds?

2739.95 parts

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

a) how many would you expect to fail to meet a minimum specification limit of 35-pounds tensile strength?

z = (x-μ)/σ

x = 35 μ = 40 , σ = 5

z = 35 - 40/5

= -5/-5

= -1

Determining the Probability value from Z-Table:

P(x<35) = 0.15866

Converting to percentage = 15.866%

We are asked how many will fail to meet this specification

We have 50,000 parts

Hence,

15.866% of 50,000 parts will fail to meet the specification

= 15.866% of 50,000

= 7933 parts

Therefore, 7933 parts will fail to meet the specifications.

b) How many would have a tensile strength in excess of 48 pounds?

z = (x-μ)/σ

x = 48 μ = 40 , σ = 5

z = 48 - 40/5

z = 8/5

z = 1.6

P-value from Z-Table:

P(x<48) = 0.9452

P(x>48) = 1 - P(x<48)

1 - 0.9452

= 0.054799

Converting to percentage

= 5.4799%

Therefore, 5.4799% will have an excess of (or will be greater than) 48 pounds

We are asked, how many would have a tensile strength in excess of 48 pounds?

This would be 5.4799% of 50,000 parts

= 5.4799% × 50,000

= 2739.95

Therefore, 2739.95 parts will have a tensile strength excess of 48 pounds

Step-by-step explanation:

The required amount charged to Tiffany for 9 minutes of the car wash is $11.14. Option A is correct.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

The additional charge for the time Tiffany was at the car wash was $0.66 per minute, so the total charge for 9 minutes would be
= $0.66 * 9
= $5.94.

Adding this to the original charge of $5.20 gives a total charge,
= $5.20 + $5.94
= $11.14.

Therefore, Tiffany was charged A) $11.14.

Answer choice B is correct.

Answer:

x=15

Step-by-step explanation:

<GCB=180-5x

<EBA=9x

<DAC=8x

The sum of the three exterior angles equals 360.

(180-5x)+9x+8x=360

180-5x+9x+8x=360

-5x+9x+8x=360-180

The required equivalent ratio of the given ratio is 3/5.

Given that,
The ratio that is equivalent to 9 to 15 is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Mentioned ration,
= 9 / 15
Reducing the expression by eliminating the common factors
= 3 / 5

Thus, the required equivalent ratio of the given ratio is 3/5.

Answer:  9h+15 > 110

Step-by-step explanation: ed 2020

$518.5 = $375 + $41x

Now that we have our equation, let's solve for the # of hours

Subtract $375 from both sides

$143.5 = $41x

Divide both sides by $41

3.5 = x

The number of labor hours was 3.5

Answer:

16 miles

Step-by-step explanation:

From the question given above, the following data were obtained:

Miles per week for training = 26 miles.

In the 5th week:

Ratio of miles ran to miles Walked is 8:5

Thus, we can obtain the miles ran by Nash in the 5th week as follow:

Ratio ran = 8

Ratio walked = 5

Total ratio = 8 + 5 = 13

Miles per week for training = 26 mile

Mile ran in the 5th week = 8/13 × 26

Mile ran in the 5th week = 8 × 2

Mile ran in the 5th week = 16 miles

Therefore, Nash ran 16 miles in the 5th week of training.

Answer:

13 glasses

Step-by-step explanation:

Given:

Amount of of lemonade available = 20⅜ cups

Amount of lemonade per guest = 1½ cups

Required:

Number of glasses to be filled

SOLUTION:

Number of glass to be filled = amount of lemonade available ÷ amount of lemonade per guest

= 20⅜ ÷ 1½

Change both mixed fractions to improper fractions

= [tex] \frac{163}{8} [/tex] ÷ [tex] \frac{3}{2} [/tex]

Flip the fraction on your right upside down and change the division to multiplication

[tex] = \frac{163}{8} * \frac{2}{3} [/tex]

[tex] = \frac{163*2}{8*3} [/tex]

[tex] = \frac{163*1}{4*3} [/tex]

[tex] = \frac{163}{12} = 13.58 [/tex]

Number of glasses that would be filled is roughly 13 glasses.

Answer:

Option B

Step-by-step explanation:

For option A:

4 pack of 3.2-ounce servings of applesauce cost $2.50. This implies that 4 × 3.2 ounce = 12.8 ounce servings of applesauce cost $2.50. Hence:

The unit rate = $2.50 / 12.8 ounce = $0.1953 per ounce

For option B:

24-ounce servings of applesauce cost $3.69. Hence:

The unit rate = $3.69 / 24 ounce = $0.15375 per ounce

From the unit rates of option A and option B, option B has a lesser unit rate, hence option B is a better buy.
