Jerome wants to know how many students in his school enjoy watching comedy programs on TV. He poses this question to all 28 students in his math class and finds that 70% of his classmates enjoy watching comedy programs on TV. He claims that 70% of the school's student population would be expected to enjoy watching comedy programs on TV. Is Jerome making a valid inference about this population? Yes, it is a valid inference because his classmates make up a random sample of the students in the school Yes, it is a valid inference because he asked all 28 students in his math class No, it is not a valid inference because his classmates do not make up a random sample of the students in the school No, it is not a valid inference because he asked all 28 students in his math class instead of taking a sample from his science class

The histogram below shows information about the hours students spent exercising in a week: A histogram is titled Weekly Exercise, the horizontal axis is labeled Hours of Exercise, and the vertical axis is labeled Students. The range on the horizontal axis is 0 to 4, 5 to 9, and 10 to 14. The values on the vertical axis are from 0 to 10 at intervals of 1. The first bin goes to 4, the second bin to 9, the third bin to 5.Which information is provided in the histogram? The number of students who exercised 4 hours or more The number of students who exercised 9 hours or fewer The mean hours of exercise The median hours of exercise

The steps to construct an angle bisector to a given angle using a compass and straightedge are given below. Arrange them in the correct order. Draw the point of intersection between the two arcs. Use a straightedge to draw a ray between the vertex of the given angle and the point of intersection between the two arcs. Use a compass to swing an arc from the vertex of the given angle that intersects both rays of that angle. From the intersection points between the arc and each ray, use a compass to draw two equal arcs (one arc from each point) inside the given angle that will intersect. Draw the two points of intersection between the arc and each ray of the given angle.

Stephen evaluated (6.34 x 10^-7)(4.5 x 10^3). His work is shown below. Which statements describe his errors? Check all that apply.(6.34 x 10^-7)(4.5 x 10^3)(6.34 x 4.5)(10^-7 x 10^3)28.53 x 10^-4-28.53 x 10^4-2.853 x 10^3 A. He changed the sign of the coefficient. A negative exponent does not affect the sign of a coefficient in scientific notation. The sign of the exponent determines the direction the decimal is moved in.B. He rewrote -28.53 x 10^4 incorrectly; 28.53 x 10^4 = 2.853 x 10^5. The exponent is increased to account for the extra place the decimal is moved.C. He did not correctly evaluate the exponent. It should be evaluated as (10^-7 x 10^3) = 10^3 since exponents are evaluated using the same operation as the coefficients.D. He got the wrong value for the coefficients; 28.53 x 10^-4 is not possible. The coefficients in scientific notation are always greater than 1, but less than 10. F. He multiplied the coefficients; he should have added 6.34 and 4.5. The product of powers rule states that coefficients are added.Keep in mind that there is multiple answers.
