Answer:
34/45 pi
Step-by-step explanation:
To change from degrees to radians, multiply by pi/180
136 * pi/180
34/45 pi
Answer:
Simple linear equation is :
Y = 86.784 - 2.67x
Step-by-step explanation:
The educator wants to see the relationship between no of absences and final grades of the student. No. of absence of student is independent variable while final grade is dependent variable. The final grades of the student are dependent on the no. of absence they do.
b = Sxy / Sxx
b = { 2312 [ 37 * 422 ] / 6 } / 337 - 37^2 / 6 = -2.67
a = -2.67 * 37/6 = 86.784
Answer: The director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.
Step-by-step explanation:
Given : The total number of singers auditioning for the school musical.= 12
The director wanted choose first a lead singer and then a stand-in for the lead singer.
We use Permutations here because order of selecting the singers matters.
The number of permutations of selecting r things out of n things =
Similarly , the number of ways to select 2 singers in an order from 12 singers
Hence, the director can choose first a lead singer and then a stand-in for the lead singer in 132 ways.
Its udefined because the question asked describe the line of a slope, now its not negative or positive because there is no change. Its undefined because its a line, going vertical way
Answer:
C: y ≤ 2x − 2 y > −x + 3
Step-by-step explanation:
The shading for region A is above a dashed line with negative slope, so will be the solution of an inequality that matches y > -ax +b. Choices A and C have such an inequality.
The shading for region B is below a solid line with positive slope, so will be the solution of an inequality that matches y ≤ ax +b (for some positive a). Choice C is the only one wht the appropriate inequality symbol.
Comparing choice C in detail with the graph, we find that it matches. The line with negative slope has a slope of -1 and a y-intercept of 3, so region A matches y > -x+3. The line with positive slope has a slope of +2 and a y-intercept of -2, so region B matches y ≤ 2x -2.
