Helen is trying to determine the volume of a figure made from two rectangular prisms as shown in the figure. One prism has the dimensions of 1 cm by 1 cm by 1 cm. What are the dimensions of the other prism? 2 prisms are joined together to make 1 figure. The tall prism is 1 centimeter wide and 1 centimeter long. Its height is 3 centimeters. The length of the small and tall prism together is 3 centimeters. The small prism is 2 centimeters tall and 1 centimeter wide. A 1 cm by 2 cm by 2 cm B 1 cm by 1 cm by 3 cm C 3 cm by 3 cm by 2 cm D 1 cm by 2 cm by 3 cm

Rose drew a regression line for this paired data set. her line passed through (1, 2) and (3, 5) . what is the equation of rose's regression line?

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
