Answer:
X = 3
Step-by-step explanation:
3x + 4x - 12 = - 10x + 30 + 9
7x - 12 = - 10x + 39
7x + 10x = 12 + 39
17x = 51
x = 3
Answer:
6 or 2
Step-by-step explanation:
f(x) = 0.5|x - 4| + 6
0.5|x - 4| + 6 = 7
0.5|x - 4| = 7-6
0.5|x - 4| = 1
|x - 4| = 2
x -4 = ± 2
x-4 = 2 ==> x = 6
x-4 = -2 => x = 2
so the value of x = 6 or 2
Solution: We have z score = 3.74.
It means, a basketball player's height is 3.74 standard deviation's above the mean.
Z score tells us how many standard deviations below or above the population mean a raw score is. For example if z score = -2, it means the raw score is 2 standard deviations below the mean value. If z score = 2, it means the raw score is 2 standard deviations above the mean value.
Hence the basketball player's height (201 cm) is 3.74 standard deviation's above the mean.
