Z-score for a variable X is calculated using
Z(x)=(x-mean)/standard deviation.
Here
x=56
mean=65
standard deviation=5
so
Z(65)=(65-56)/5=9/5=1.8
Answer:
No because it going down
Step-by-step explanation:
Answer:
answer: -5
Step-by-step explanation:
-5 × 3.8 = -19 so therefore x = -5
You just plug 0 in for either x or y to get the other intercept since it’s in standard form
8x=35
X= 35/8
-7y=35
Y=-5
X-intercept: 35/8
Y intercept: -5
