The <u>correct answer</u> is:
Experiment
Explanation:
In an experiment, one group is given a treatment while at least one other group is not. After the treatment is finished, the results of the group that receive the treatment are compared with the results of the group (or groups) that do not receive the treatment, to determine if the treatment had any effect on the group.
In this problem, the different groups are the classes. Some classes use the new method, which is the treatment, while other classes do not. At the end of the year, the reading results of each class are compared to see if the treatment (new method) had any effect.
Answer:
the Diagonal is 41 units
Step-by-step explanation:
Since the sides of a rectangle, to be a rectangle, meet at 90° we use Pythagorean Theorem a² + b² = c²
Width and Length are the legs and the diagonal is the hypotenuse
9² + 40² = c²
81 + 1600 = c²
1681 = c²
√1681 = √c²
41 = c
Answer:
158 cases
Step-by-step explanation:
Given tbe quadratic regression model :
y = -2x^2 + 40x + 8
y = number of cases of a new disease
x = number of years
The predicted number of cases of a new disease in 15 years can be calculated thus ;
Put x = 15 in the equation ;
y = -2(15)^2 + 40(15) + 8
y = - 2 * 225 + 600 + 8
y = - 450 + 600 + 8
y = 158
158 cases
