The time it takes a student to walk from the dorm to the chemistry lab follows roughly a Normaldistribution with a mean of 20 mi

creativ13 [48]

Answer:

95.15%

Step-by-step explanation:

We have that the mean (m) is equal to 20, the standard deviation (sd) 3

They ask us for P (x <25)

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

z = (x - m) / sd

We have all these values, replacing we have:

z = (25 - 20) / (3)

z = 1.66

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

P (z <1.66) = 0.9515

Which means that the probability that it arrives before 25 minutes is 95.15%

M3+ 3 m3 + 4 m²<br><br>simplify

Kipish [7]

Answer:

${m}^{3} + {27}^{m} + 4 {m}^{2}$

Step-by-step explanation:

${m}^{3} + {3}^{m 3} + 4 {m}^{2}$

${m}^{3} + {3}^{m \times 3} + 4 {m}^{2}$

${m}^{3} + {3}^{3m} + 4 {m}^{2}$

${3}^{3m} = ({3}^{3} {)}^{m} = {27}^{m}$

➡️ ${m}^{3} + {27}^{m} + 4 {m}^{2}$

4) Choose the correct inequality for this situation.

Ksenya-84 [330]

Answer:

B. 21x + 40 ≤ 124

Step-by-step Explanation:

Maximum amount budgeted = $124 (this means they can't spend more than this)

x = number of people

Cost per head = $21

Given that Mr Walter already spent $40, which is part of the money budgeted, the number of people that can go canoeing cam be expressed with the following inequality:

21x + 40 ≤ 124

(note: the amount total to be spent will either be equal to or greater than $124, because it's the maximum amount budgeted for spending).
