Answer:

T = a + (n-1)d

Step-by-step explanation:

The arithmetic progression formula could be used to represent the series

T = a + (n-1)d

Where a = number of miles before increase

d = intended additional number of miles each day

n= number of days

Hence on the 2nd day, number of miles to be covered by Jeff will be

T = a + (2-1)d = a + d

Which of the following is an arithmetic sequence?
guajiro [1.7K]

Answer:

D

Step-by-step explanation:

In an arithmetic sequence, the order must be least to greatest and there must be a consecutive sequence in addition, not any other operation. A is wrong because it is in greatest to least. B is wrong because 0 is the least so all 0's should be at the front instead. C is wrong because each following value is x2.

he blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 247.3 and a standard deviation of 6
Ulleksa [173]

Answer:

The approximate percentage of women with platelet counts within 3 standard deviations of the​ mean is 99.7%.

Step-by-step explanation:

We are given that the blood platelet counts of a group of women have a​ bell-shaped distribution with a mean of 247.3 and a standard deviation of 60.7.

Let X = <em>t</em><u><em>he blood platelet counts of a group of women</em></u>

The z-score probability distribution for the normal distribution is given by;

                                Z  =  \frac{X-\mu}{\sigma}  ~ N(0,1)

where, \mu = population mean = 247.3

           \sigma = standard deviation = 60.7

Now, according to the empirical rule;

  • 68% of the data values lie within one standard deviation of the mean.
  • 95% of the data values lie within two standard deviations of the mean.
  • 99.7% of the data values lie within three standard deviations of the mean.

Since it is stated that we have to calculate the approximate percentage of women with platelet counts within 3 standard deviations of the​ mean, or between 65.2 and 429.4, i.e;

         z-score for 65.2 =  \frac{X-\mu}{\sigma}

                                     =  \frac{65.2-247.3}{60.7}  = -3

         z-score for 429.4 =  \frac{X-\mu}{\sigma}

                                       =  \frac{429.4-247.3}{60.7}  = 3

So, it means that the approximate percentage of women with platelet counts within 3 standard deviations of the​ mean is 99.7%.
