If each yard of material costs $4.84, then you just take this amount and multiply it by 2.45. Therefore 2.45 x 4.84=11.86. Your answer is $11.86.
(10^2 +10^2)^.5 = 10*(sqrt2)
Answer: 90 words per minute
====================================================
Work Shown:
270 words : 3 minutes
270/3 words : 3/3 minutes ..... divide both parts by 3
90 words : 1 minute
Brayden can type 90 words per minute (wpm).
Probability of graduating is 73% = 0.73
Probability of not graduating = 1-73% = 0.27
Number of students (n) = 15
Number of graduates (x) = 8
Use the binomial probability formula:
P(x) = (n/x) *p^x * (1-p)^n-x
P(8) = 15/8 * 0.73^8 * 0.27^7
P(8) = 0.0543
Rounded to nearest hundredth = 0.05
