According to records, the amount of precipitation in a certain city on a November day has a mean of 0.10 inches, with a standard

Andru [333]

Answer:

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 0.10 inches

Given that the standard deviation of the population = 0.07inches

Let 'X' be a random variable in a normal distribution

$Z = \frac{x-mean}{S.D} = \frac{0.11-0.10}{0.07} = 0.1428$

Step(ii):-

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = P(Z≤0.1428)

= 1-P(Z≥0.1428)

= 1 - ( 0.5 +A(0.1428)

= 0.5 - A(0.1428)

= 0.5 -0.0596

= 0.4404

Final answer:-

The probability that the mean daily precipitation will be 0.11 inches or less for a random sample of November days

P(X≤ 0.11) = 0.4404

If H is the circumcenter of triangle BCD, find each measure. CD, CE, HD, GD, HG, HF

Levart [38]

Answer:

H is the circumcenter of triangle BCD

CD = 2FD = 2*32 = 64
CE = BE = 26
HD = HC = 33
GD = 1/2BD = 1/2(58) = 29
HG = √HD ²-GD² = √33²-29² = 2√62 ≈ 15.75
HF = √HD ²-FD² = √33²-32² =√65 ≈ 8.06

Use the formula a^(x/n) = (n)√a^x (note it is a small n)

(5x^4y^3)^(2/9) = Small 9

Convert.

$\sqrt{9{{(25x^{8})y^9 }}}$ is your answer

hope this helps
