Answer:
x=15 i think but im pretty sure
Step-by-step explanation:
1.5 - 0.25(a + 4)= 3 + 3(0.05 - 0.5a)
Answer: 69
Step-by-step explanation: Percent multiplied by the total number of students: 8/100 x 75 = 600/100. (remember it is 8/100 because it’s 8%.)
Then you simplify which will then get you 6.
Afterwards you need to subtract those 6 students from the group of 75. 75-6=69. So, 69 students.

Answer:
(78, 80)
Step-by-step explanation:
Given a normal distribution :
Mean = 79 seconds
Standard deviation = 0.5 seconds
Using the empirical rule :
95% of her finishing times :
According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.
Hence ;
The interval will be defined as ;
Mean ± 2(standard deviation)
79 ± 2(0.5)
79 ± 1
(79 - 1) ; (79 + 1)
78 ; 80
-6 -5 -4 -3 -2 -1
2 3 4 5 6
