Answer:
(x+2)(x+5) or if you were looking for the x-intercepts they would be -5, and -2
For this case we observe that the three angles of the triangle are equal. Also, we have by definition:
A triangle is equilateral, when the three sides have the same length (in addition, the three internal angles measure 60 degrees or
.
Answer:
The three sides have the same length
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:
answer i d
Step-by-step explanation:
Answer:
The circumference is approximately 125.66.
Step-by-step explanation:
The formula for circumference is 2 x 3.14(r). Radius (or r) in this case is equal to 20 since the diameter is two times the length of the radius. 40/2 = 20.
2 x 3.14(20) ≈ 125.66
