Mathematics
1 answer:
pashok25 [27]3 years ago
3 0

Answer:

value of k = 6

Step-by-step explanation:

sum of all angles forming a straight line = 180°

so,

  • 7k + 8 + 90 + 40 = 180
  • 7k + 138 = 180
  • 7k = 180 - 138
  • 7k = 42
  • k = 42/7
  • k = 6

hence the value of k = 6

​claim: the mean pulse rate​ (in beats per​ minute) of adult males is equal to 69 bpm. for a random sample of 140 adult​ males,
zaharov [31]

Answer:

93.19%

Step-by-step explanation:

We have that the mean (m) is equal to 70.4, the standard deviation (sd) 11.1 and the sample size (n) = 140

They ask us for P (x =69)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / (sd / (n ^ 1/2))

We have all these values, replacing we have:

z = (69 - 70.4) / (11.1 / (140 ^ (1/2)))

z = 1.49

With the normal distribution table (attached), we have that at that value, the probability is:

P (z <1.49) = 0.9319

The probability is 93.19%
