To solve this, we need to use the z test. The formula for
z score is:
z = (x – u) / s
where x is sample value = 141.4 mm and above, u is mean
value = 140 mm, s is standard dev = 8 mm.
z = (141.4 – 140) / 8
z = 0.175
From the standard probability tables, the p value at z =
0.175 using right tailed test is:
P = 0.4306
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Distance is always positive
|-10-0|=10
Mark me brainliest!!
Complementary angles = 90
x+y =90
y=x+24
substitute this in to the equation
x+x+24=90
2x+24=90
subtract 24 from each side
2x = 66
divide by 2
x=33
y = 33+24
y=57
Answer: 33, 57
Answer:
x=1 and y=2
