Z score = 66 - 76
---------- = - 1
10
from the tables of normal distribution this corresponds to 0.34-3 of the area under the normal curve
so reuired number od students = 0.3413 * 230 = 78
Answer:
y=4x−14
Step-by-step explanation:
solve for y.
y+2=4(x−3)
distribute 4
y+2=4x-12
subtract 2 from both sides
y+2+−2=4x−12+−2
y=4x−14
Answer:
y=4x−14
Answer:
m>5
Step-by-step explanation:
Let's solve your inequality step-by-step.
m+4>9
Step 1: Subtract 4 from both sides.
m+4−4>9−4
m>5
Answer:
x = 2 1/3
y = 14 / (2 1/3) = 14 / (7/3) = 14*3/7 = 42/7 = 6
y = 6
x = 4 1/5
y = 14 / (4 1/5) = 14 / (21/5) = 14*5/21 = 70/21 = 3 7/21 = 3 1/3
y = 3 1/3
x = 7/6
y = 14 / (7/6) = 14*6 / 7 = 12
y = 12
