Answer:

D=565.6m

Step-by-step explanation:

From the question we are told that:

Diameter d=36m

Number of times jogged N=5

Generally the equation for Distance traveled is mathematically given by

D=Circumference of Park * Number of times jogged

Where

Circumference of Park c is mathematically give as

 c=2\pi r

 c=2 3.142*\frac{36}{2}

 c=113.1

Therefore

 D=c*N

 D=113.1*5

 D=565.6m

Find the nth term of the sequence:<br>23, 19, 13, 5, -5.......<br>​
Maurinko [17]

Answer:

Step-by-step explanation:

Given the sequence :

23, 19, 13, 5, -5.......

From the sequence, the common difference is unequal, as their is a constant Increment in the difference after successive numbers.

19 - 23 = -4

13 - 19 = -6

5 - 13 = -8

-5 - 5= -10

Hence an constant difference of - 2 after each successive difference.

Hence, this is a quadratic sequence

With the formula

an² + bn + c

What is the x and y intercept
nika2105 [10]

Answer:

x-intercept:  (-2,0); y-intercept:  (0,4)

Step-by-step explanation:

First, focus on the y-axis.  This axis is described by the equation x = 0.  From the graph we see that the line crosses the y-axis at (0,4).  This is the y-intercept.

Next, focus on the x-axis, which is described by y = 0.  The line crosses the x-axis at (-2,0).  This is the x-intercept.

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical ru
Harlamova29_29 [7]

Answer:

1.35%

Step-by-step explanation:

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical rule, what ? Please do not round your answer.

Empirical rule formula states that:

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

We don't know the number of Standard deviation yet , hence:

Mean = 104

Standard deviation = 15.

At least 59

Hence:

104 - 15x = 59

104 - 59 = 15x

45 = 15x

x = 45/15

x = 3

Hence, At least 59 is 3 standard deviations away from the mean on one side of the distribution thus,

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

100% - 99.7%

= 0.003

Since it is on one side of the distribution:

= 1.5% - 0.3%

= 0.015 - 0.0015

= 0.00135

Converting to percentage

= 1.35%

The percentage of IQ scores that are at least 59 is 1.35%
