Chipotle Burritos are normal distributed with a mean length of 200mm and a standard deviation of 8mm. What is the probability that a burito picked at random is shorter than 190mm?

Answers

Answer: 0.1056

Step-by-step explanation:

Given: Chipotle Burritos are normal distributed with

Mean =  200 mm

Standard deviation = 8 mm

Let x be the length of a random burrito.

The probability that a burrito picked at random is shorter than 190mm will be :

[tex]P(x<190)=P(\dfrac{x-\mu}{\sigma}<\dfrac{190-200}{8})\\\\=P(z<-1.25)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.25)\\\\=1-0.8944\\\\=0.1056[/tex]

Hence, the probability that a burrito picked at random is shorter than 190mm is 0.1056.

You can text 44 words in 1 minute. Write a proportion to help you find
how many words you can type in 4 minutes. Which choice sets up the
proportion correctly and has the correct solution?

Answers

Answer:

176 words

Step-by-step explanation:

1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:

44 words = x

1 minutes = 4 minutes

2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.

3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!

4) multiplying 44 by 4 would get us our answer which is 176

Answer:

m∠M = 47°

m∠R =  124°

Step-by-step explanation:

HOME = TRAP

Judging buy the picture there is only one corner that sticks out compared to the rest of the angles. Meaning that A and M are the same because they are the only angles that are easily identical to each other. Then match the letters using this information

m∠A = m∠M

m∠R = m∠O

m∠T = m∠H

m∠P = m∠E

Now all you need to find is m∠R and m∠M

m∠A = m∠M means m∠M = 47° since m∠A is 47°

Same concept goes for m∠R = m∠O.

Answer:  I would go with A. f(x) = 4x + 3

Nothing further can be done with this topic. Please check the expression entered or try another topic.

f ( x ) = 4 x + 3 ,     f ( x ) = − 4 x − 3 ,     f (x ) = x + 3 ,     f ( x ) = x + 3

Step-by-step explanation:  Set up the composite function and evaluate.

f ( 4 x + 3 ) = 16 x + 15

Graph.

f ( x ) = 4 x + 3

f ( x ) = − 4 x − 3

f ( x ) = x + 3

f ( x ) = x + 3

The individual credit with the creation of vaccines and the eradication of polio is? Consider two neighboring island countries called Arcadia and Felicidad. They each have 4 million labor hours available per week that they can use to produce jeans, corn, or a combination of both. The following table shows the amount of jeans or corn that can be produced using 1 hour of labor. Jeans CornCountry (Pairs per hour of labor) (Bushels per hour of labor)Arcadia 8 16Felicidad 5 20Initially, suppose Arcadia uses 1 million hours of labor per week to produce jeans and 3 million hours per week to produce corn, while Felicidad uses 3 million hours of labor per week to produce jeans and 1 million hours per week to produce corn. Consequently, Arcadia produces 8 million pairs of jeans and 48 million bushels of corn, and Felicidad produces 15 million pairs of jeans and 20 million bushels of corn. Assume there are no other countries willing to trade goods, so, in the absence of trade between these two countries, each country consumes the amount of jeans and corn it produces.Arcadia's opportunity cost of producing 1 pair of jeans is____of corn, and Felicidad's opportunity cost of producing 1 pair of jeans is____of corn. Therefore,____has a comparative advantage in the production of jeans, and____has a comparative advantage in the production of corn. Suppose that each country completely specializes in the production of the good in which it has a comparative advantage, producing only that good. In this case, the country that produces jeans will produce ___ million pairs per week, and the country that produces corn will produce ____ million bushels per week.When the two countries did not specialize, the total production of jeans was 23 million pairs per week, and the total production of corn was 68 million bushels per week. Because of specialization, the total production of jeans has increased by____million pairs per week, and the total production of corn has increased by____million bushels per week.Because the two countries produce more jeans and more corn under specialization, each country is able to gain from trade.Calculate the gains from tradethat is, the amount by which each country has increased its consumption of each good relative to the first row of the table.
