Graph the first six terms of a sequence where a1 = 3 and d = −10.

Mathematics
1 answer:
Aleks [24]3 years ago
7 0

Answer:

Step-by-step explanation:

nth term = (n-1)th term + common difference

d = -10

a₁ = 3

a₂ = a₁ + d = 3 + (-10) = -7

a₃ = a₂ + d = -7 + (-10) = -17

a₄ = a₃ + d = -17 + (-10) = -27

a₅ =a₄ + d = -27 + (-10) = -37

a₆ = a₅ + d = -37 + (-10) = -47

First six terms: 3 , -7 , -17, -27, -37 , -47

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 130lb and 1
Vlad [161]

Answer: 0.4758

Step-by-step explanation:

Given : Mean : \mu=137\text{ lb}

Standard deviation : \sigma =28.9\text{ lb}

Also, the new population of pilots has normally distributed .

The formula to calculate the z-score :-

z=\dfrac{x-\mu}{\sigma}

For x=130 lb .

z=\dfrac{130-137}{28.9}=-0.2422145\approx-0.24

For x=171lb.

z=\dfrac{171-137}{28.9}=1.1764705\approx1.18

The p-value =P(-0.24

=0.8809999-0.4051651=0.4758348\approx0.4758348\approx0.4758

Hence, the required probability : 0.4758

Answer:

D. \frac{2}{5}

Step-by-step explanation:

Since we know that the odds of an events can be found by dividing the probability that an event will occur by the probability that the event will not occur.

\text{Odds of an event}=\frac{\text{Probability that event will occur}}{\text{Probability that event will not occur}}

Probability of an event not occurring can be found by subtracting probability of the event occurring from 1.

\text{Odds of an event}=\frac{\text{Probability that event will occur}}{1-\text{Probability that event will occur} }  

We have been given that probability of an event is 2/7.  

Upon substituting our given values in above formula we will get,

\text{Odds of the given event}=\frac{\frac{2}{7}}{1-\frac{2}{7}} }

\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{7-2}{7}} }

\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{5}{7}} }

\text{Odds of the given event}=\frac{2}{7}\times \frac{7}{5}

\text{Odds of the given event}=\frac{2}{5}

Therefore, the odds of the same event are \frac{2}{5} and option D is the correct choice.
