Answer:
AB = 5
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
=> 3² + 4² = AB²
=> AB =
=> AB = 5
Step-by-step explanation:
OK so the origin is zero.
From A to B it would be 0 units right and 4 units up
B to C would be 4 units right and 0 units up
C to A would be 4 units left and 5 units down
Answer:
73.1 inches
Step-by-step explanation:
We solve for this using z score formula.
z-score is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
x = unknown = randomly selected male's height
μ = 70.3 inches
σ = 4.1 inches
z = is not given but we are given its percentile which is 75
The z score for a 75th percentile = 0.674
Hence,
0.674 = x - 70.3/4.1
Cross Multiply
0.674 × 4.1 = x - 70.3
2.7634 = x - 70.3
x = 70.3 + 2.7634
x = 73.0634 inches
The height of the randomly selected male = 73.0634
Therefore, the height of the randomly selected male to the nearest tenth of an inch is 73.1 inches
Answer:
C
Step-by-step explanation:
Answer:
x + z = 180
x = 180 - z
y + z +10 = 180
y = 170 - z
w + z - 13 = 180
w = 193 - z
x + y + w = 180⁰
180 - z + 170 - z + 193 - z = 180
-3z = -363
z = 121⁰
