Answer:
the first 1
Step-by-step explanation:
Answer:
Company X - 190 students
Company Y - 114 students
No phones - 76 students
Step-by-step explanation:
1) Find a multiplier to get the ratio from sample to population; to compare the sample to the population
380/120 = 3.16666667 or 3 & 1/6
380 comes from the total population of students and 120 comes from the randomly selected.
2) Use our multiplier to compare the results to the population
<u>People with Company X</u>
<u>People with Company Y </u>
<u>People with no cell phone</u>
- 24 * 3.166667 = 76.0000000001 = 76 (rounded)
<u>Double check</u>
190 + 114 + 76 = 380
Basically (g of f)x=(f(g(x)) so
g of f=f(g(x))=7(5x^2+4x-3)+5
distribute
f(g(x))=35x^2+28x-21+5=35x^2+28x-16
g of f=35x^2+28x-16
Answer:
243
Step-by-step explanation:
3^2 x 3^3 is the same as 3x3 x 3x3x3 which is 9x27 which is 243
