Select the correct answer. Hair Color/Height Less than 175 cm 175 to 180 cm Above 180 cm Total Black 28 33 29 90 Brown 37 24 19 80 Blond 21 33 26 80 Total 86 90 74 250 250 employees in an organization were surveyed about their hair color and height. The data collected is presented in the table. If a person is selected at random, what is the probability that the person is at least 175 centimeters tall? A. 0.296 B. 0.344 C. 0.360 D. 0.656

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

the correct answer is d

hope this

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:
