Answer:
the 3rd one. the rest are randomized.
Step-by-step explanation:
Answer:
370
Step-by-step explanation:
The venn diagram corresponds to students who were sick in January at a Chicago high school.
Students who had only fever= n(A) = 80
Students who had only headache= n(B) = 90
Students who had only cough = n(C) =60
Students who had both cough and fever = n(AC) = 10
n(AB) = 40:n(BC) = 30 n(ABC) = 20
Hence total students = 800
no of students who were absent due to other reasons = 100
REmaining students = 700
Students who were sick = sum of all =330
So no of students who were at school = 700-330 = 370
Answer:
The sum of the coefficients of the terms in (-1.5·x² + 0.5·x + 4)¹⁶ that have even degree is -4273411167.501
Step-by-step explanation:
The parameters given are;
f(-4) = -22
f(-1) = 2
f(2) = -1
g(x) = f(x)¹⁶
The function f(x) is presented as follows;
f(x) = a·x² + b·x +c
We have;
-22 = a·(-4)² + b·(-4) +c
-22 = a·16 - 4·b +c ..............(1)
2 = a·(-1)² + b·(-1) +c
2 = a - b +c...........................(2)
-1 = a·(2)² + b·(2) +c
-1 = 4·a + 2·b +c...................(3)
Solving the equations (1), (2), and (3) by using an online linear systems solver, we get;
a = -1.5, b = 0.5, c = 4
Therefore, f(x) = -1.5·x² + 0.5·x + 4
f(x)¹⁶ = (-1.5·x² + 0.5·x + 4)¹⁶ which gives the coefficients of the even terms as follows;
656.841 - 19267.331 + 248302.054 - 1772904.419 + 6735603.932 - 2868054.635 - 119602865.901 + 750783340.827 + -2542435585.611 + 5338903756.992 - 6048065910.25 -1031335136 + 17223697920 - 32238338048 + 32107397120 - 17716740096 = -4273411167.501.
This sentence is key: "At this point, he is 3 blocks from school and half way there"
<span>since 3 blocks is halfway of the trip, that means the total distance is 6 blocks </span>
<span>from the stoplight to the library must be one block, and one block took him 4 minutes </span>
<span>therefore, therefore, the total trip takes 4 * 6 = 24 minutes, or 4 * 3 = 12 minutes from the library </span>
<span>8:24 + 12 = 8:36 </span>
<span>he arrives at school at 8:36 </span>
<span>(and yes, make sure to sketch this out!)</span>
