This is really simple if you know anything about combinations in geometry i just have not done these problems in awhile which answer choice is equivalent to the expression (10! +7! )6! ? 17⋅16⋅15⋅14⋅13⋅12⋅11⋅10⋅9⋅8⋅7 4⋅3⋅2⋅1+7 10⋅9⋅8⋅7+7 4⋅3⋅2⋅1+1 7⋅6⋅5⋅4

Jonathan pays $1.90 per pound for potatoes. he buys 8.3 pounds of potatoes. he determines that he will pay $15.77, before tax, for the potatoes. which best describes the reasonableness of jonathan’s solution? jonathan’s answer is reasonable because there are two decimal places in the factors and two in the product. jonathan’s answer is unreasonable because there are three decimal places in the factors and two in the product. jonathan’s answer is reasonable because is 16, and 16 is close to 15.77. jonathan’s answer is unreasonable because is 8, and 8 is not very close to 15.77.

What could explain what happened when the time was equal to 120 minutes

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?
