The constant of proportionality is: 0.2 and the equation is: c = 0.2t

Step-by-step explanation:

Let t be the number of texts and c be the cost

Then according to given statement

c ∝ t

The proportionality symbol will be removed and a constant f proportionality will be introduced.

$c = kt$

For constant of proportionality:

$3.20 = k * 16\\k = \frac{3.20}{16}\\k = 0.2$

Hence the constant of proportionality is 0.2

Equation:

$c = 0.2t$

Hence,

The constant of proportionality is: 0.2 and the equation is: c = 0.2t

Answer:

p hat≈N(0.34,0.0273)

Step-by-step explanation:

Given information p=0.34

Number of random samples=300

The sampling distribution of p hat is

p∧≈N(0.34,\sqrt{\frac{0.34(1-0.34)}{300}})

≈N(0.34,0.0273)

Running times for 400 meters are Normally distributed for young men between 18 and 30 years of age with a mean of 93 seconds and

Luda [366]

Answer:

C. 45 and 141 seconds

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 93 seconds

Standard deviation = 16 seconds

99.7% of running times are approximately between:

By the Empirical rule, within 3 standard deviations of the mean, so between 3 standard deviations below the mean and 3 standard deviations above the mean

3 stnadard deviations below the mean

93 - 3*16 = 45 seconds

3 standard deviations above the mean

93 + 3*16 = 141 seconds

The correct answer is:

C. 45 and 141 seconds
