Given two situations below, determine which one is more unusual and explain how you know (no calculations necessary). 1. The mean number of candy hearts in a box is 60, with standard deviation of 3. The box of candy that Clare bought for Valentine's day only had 54 candies in it.

2. Niki bought a bag of Cheese Puffs that is supposed to weigh 17.5 ounces with a standard deviation of 0.5 oz. He chose a bag that felt heavy. When he got home and weighed it, it was 18.1 oz.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

idk idk idk idk idk

step-by-step explanation:

the weight of the object inside the box!

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
