The table below shows the frequency distribution of the weights (in grams) of pre-1964 quarters. Choose the correct histogram below. Weight (g) 6.000-6.049 Frequency OA. o 20 15- 10- 3 6.050-6.099 6.100-6.149 6.150-6.199 8 12 6.200-6.249 10 6.1 6.2 6.3 64 6.250-6.299 Weight (grams) 6 6.300-6.349 3 OB. 6.350-6.399 1 Use the frequency distribution to construct a histogram. Does the histogram appear to depict data that have a normal distribution? Why or why not? 6.1 6.2 6.3 Weight (grams) 6.4 Oc. 15 6.1 62 6.3 Weight (grams) Does the histogram appear to depict data that have a normal distribution? O A. The histogram does not appear to depict a normal distribution. The frequencies generally increase and the histogram is roughly symmetric. O B. The histogram does not appear to depict a normal distribution. The frequencies generally decrease to a minimum and then increase, and the histogram is roughly symmetric. OC. The histogram appears to depict a normal distribution. The frequencies generally increase to a maximum and then decrease, and the histogram is roughly symmetric. O D. The histogram appears to depict a normal distribution. The frequencies generally decrease to a minimum and then increase.

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Addition
