Answer:
2
Step-by-step explanation:
Its simple.
7^{2} + 7^{2} = C^{2}
49 + 49 = C^{2}
98 = C^{2}
9.8 ≈ C
10 ≈ C
C = hypotenuse
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:
240
Step-by-step explanation:
you do 3x10 which is 30 then multiply that by 8 and you have your answer.
Answer:
Step-by-step explanation:
- x² + 6x - 3 = 0
- x² + 2*3*x + 3² - 3 = 3²
- (x + 3)² = 12
- x + 3 = ± √12
- x + 3 = ± 2√3
- x = 2.196, x = -8.196
