A study investigated about 3000 meals ordered from Chipotle restaurants using the online site Grubhub. Researchers calculated the sodium content (in milligrams) for each order based on Chipotle's published nutrition information. The distribution of sodium content is approximately Normal with mean 2000 mg and standard deviation 500 mg. About what percent of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium?

Answers

Answer 1

Answer:

21.186%

Step-by-step explanation:

z = (x-μ)/σ,

where

x is the raw score = 2400mg

μ is the population mean = 2000mg

σ is the population standard deviation = 500mg

z = 2400 - 2000/500

z = 0.8

Probability value from Z-Table:

P(x<2400) = 0.78814

P(x>2400) = 1 - P(x<2400) = 0.21186

Converting to percentage:

0.21186 × 100

= 21.186%

Therefore, the percent of the meals

ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%

Answer 2

21.186% of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium.

It is known that 3000 meals ordered from Chipotle restaurants using the online site Grubhub.

And the distribution of sodium content is approximately Normal with mean 2000mg and standard deviation 500 mg.

We know,

[tex]z = \frac{(x- \mu)}{\(\sigma\)}[/tex],

And daily allowance of 2400 mg of sodium

x is the raw score = 2400mg

μ is the population mean = 2000mg

σ is the population standard deviation = 500mg

[tex]z = \frac{2400 - 2000}{500}[/tex]

z = 0.8

Probability value from Z-Table:

[tex]P(x<2400) = 0.78814\\P(x>2400) = 1 - P(x<2400) \\= 0.21186[/tex]

Converting to percentage:

[tex]= 0.21186 (100)\\= 21.186%[/tex]

Therefore, the percent of the meals  ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%.

Anthony resells shoes that he purchases. He bought a pair for $210, and then applied a 43% markup. How much will the shoes be sold for?

Answers

To find how much 43% of 210 is, we do a part/whole=percent/100, so a/210=57/100, 210•57=11970/100=119.70, so that means that 210-119.70=90.30, so 210+90.30=300.30 as the final cost

The Panthers baseball team needs new equipment. They plan to purchase bats that cost $60 each and gloves that cost $25 each. The number of bats they will purchase is half the number of gloves they will purchase. If they have $700, how many of each can they buy?

Answers

Answer:

Therefore, they can buy

6.36 bats and 12.72gloves

Step-by-step explanation:

Let us represent:

The number of bats purchased = b

The number of gloves purchased = g

We are told in the question that:

The number of bats they will purchase is half the number of gloves

b = 1/2g

b = g/2

g = 2b

The teams plan to purchase bats that cost $60 each and gloves that cost $25 each. they will purchase. If they have $700, how many of each can they buy?

Hence:

$60 × b + $25 × g = $700

= 60b + 25g = 700

We substitute 2b for g

60b + 25(2b) = 700

60b + 50b = 700

110b = 700

b = 700/110

b = 6.3636363636

b = 6.36 bats

Therefore, the number of bats they can buy = 6.36 bats

Remember:

g = 2b

b = 6.36

Hence,

g = 2 × 6.36

g =12.72

Therefore, the number of gloves = 12.72 gloves

From the graph and data points, you can observe that Group B has a HIGHER range and has a greater variability. so it's NOT 1. 4. or 3. THEREFORE it's 2.

and subtracting the first plot by the last in each graph.

Owen measured a line to be 17.9 inches long. If the actual length of the line is 17.8 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?

Answers

Answer:

0.6%

Step-by-step explanation:

Percent Error = the absolute value of (actual value observed-expected value)/(expected value) x100%

(17.8-17.9)/(17.9) = -0.006

Absolute value is 0.006

0.006 times 100% equals 0.6%

The percent error of the measurement in the length is 10%.

What is percent error in measurement?Percent error is the difference between estimated value and the actual value in comparison to the actual value and is expressed as a percentage.

Given is that Owen measured a line to be 17.9 inches long. The actual length of the line is 17.8 inches.

We can calculate the percentage error as -

%e = {(A.V. - E.V.)/(A.V.)} x 100

%e = (17.9 - 17.8) x 100

%e = 0.1 x 100

%e = 10%

Therefore, the percent error of the measurement in the length is 10%.

Given the expression  that represents the interest earned on a money given as (1.0045)^4t

In order to calculate the approximate yearly percent, we will substitute t = 1 into the expression as shown:

f(t) = (1.0045)^4t

f(1) = (1.0045)^4(1)

f(1) = (1.0045)^4

f(1) = 1.018
