Answer:
y = (12 - 4x)/5
Step-by-step explanation:
5y = 12 - 4x
y = 12/5 - 4x/5
y = (12 - 4x)/5
Answer:
- 7, - 28, - 112, - 448, - 1792, - 7168
Step-by-step explanation:
Using the recursive formula and a₁ = - 7 , then
a₂ = 4a₁ = 4 (- 7) = - 28
a₃ = 4a₂ = 4(- 28) = - 112
a₄ = 4a₃ = 4(- 112) = - 448
a₅ = 4a₄ = 4(- 448) = - 1792
a₆ = 4a₅ = 4(- 1792) = - 7168

Step-by-step explanation:
1075 students were asked how close they live to the college. The table shows the results below with some values missing. Enter the correct values in the boxes remembering to use the % symbol where necessary.
<u>20 to 25: </u>given 20%
20% of 1,075 = 215
<u>15 to 19: </u>given 12%
12% of 1,075 = 129
<u>10 to 14: </u>given 516 students
(516/1,075)*100 = 48%
<u>5 to 9: </u>given 162 students
(162/1,075)*100 = 15.07%
<u>< 5: </u>given 53 students
(53/1,075)*100 = 4.93%
The expected value of the inseam length of the jeans is found as
30% of 30+ 25% of 32+ 10% of 34+ 10% of 36 + 10% of 38 + 15% of 40
= 
= 
Hence, the third option 33.8 is the correct expected value.
