Answer: X=4
Step-by-step explanation:
Because the 90 angle is alternate exterior angle to the 21x+6. So they are equal to each other. It would be 90=21x+6. Then -6 to both sides to be 84=21x and 84/21 is 4. So X=4.
Answer:
17000 batteries
Step-by-step explanation:
Three years and one month is equivalent to the mean minus one standard deviation.
Three years and seven months is equivalent to the mean plus one standard deviation.
For a normal distribution, we know that 68% of population is between mean ± 1 sd, then can be expected that 25000*68% = 17000 of batteries last between three years and one month and three years and seven months
