A group of 50 students at the Namibia University of Science and Technology, take at least on of these subjects: Calculus(C) and ANOVA(A). 17 take both subjects, 9 take Calculus only. 8 take ANOVA only and x take neither subjects.

4.1 Represent this information on a venn diagram.

NB: For questions 4.2 to 4.4 use appropraite set notations.

4.2 Find the value of x

4.3 Find the number of students taking Calculus or ANOVA

4.4 Find the number of students taking ANOVA.

4.5 Find the number of students who are not taking Calculus.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

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:

df =

both have same length

and?
