Answer:

y = -3x + 1

Step-by-step explanation:

slope intercept form -> y=mx+b

you can find your slope, m, by doing rise over run ( up 3, left one -> -3/1 )

you can find your y-intercept, b, by just looking at the y axis ( 0,1 -> 1 )

from there you just plug in the values

y = m ( slope ) x + b ( y-intercept )

y = -3x + 1

Calculate the sample variance and sample standard deviation for the following frequency distribution of heights in centimeters f

Zolol [24]

Answer:

$\bar X = \frac{\sum_{i=1}^n X_i f_i}{n}= \frac{22026.1}{171}=128.81$

$s^2 = \frac{2839948.85- \frac{(22026.1)^2}{171}}{171-1}= 16.59$

$s= \sqrt{16.587}=4.07$

Step-by-step explanation:

For this case we can calculate the sample variance and deviation with the following table

Class Midpoint (Xi) fi Xi*fi Xi^2 *fi

120.6-123.6 122.1 17 2075.7 253443

123.7-126.7 125.2 49 6134.8 768077

126.8-129.8 128.3 29 3720.7 477365.8

129.9-132.9 131.4 41 5387.4 707904.4

133.0-136.0 134.5 35 4007.5 633158.8

___________________________________________

Total 171 22026.1 2839948.85

For this case we can calculate the mean or expected value with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i f_i}{n}= \frac{22026.1}{171}=128.81$

Now we can calculate the sample variance with the following formula:

$s^2 =\frac{\sum f_i X^2_i -[\frac{(\sum X_i f_i)}{n}]^2}{n-1}$

And if we replace we got:

$s^2 = \frac{2839948.85- \frac{(22026.1)^2}{171}}{171-1}= 16.59$

And the standard deviation would be the square root of the variance and we got:

$s= \sqrt{16.59}=4.07$

Lupita ride a taxi that charge a flate rate of $6. 75 plu $3. 20 per mile. If the taxi charge lupita $40. 03 in total for her tr

mel-nik [20]

Based on the charged amount, Lupita drove 8.76 miles.

Let us assume the number of miles rode bh Lupita be x. Forming the equation now -

Total charge = flat rate + cost per mile × number of miles

Keep the values in above mentioned equation to find the value of x

40.03 = 6.75 + 3.20×x

Rewriting the equation with respect to x

3.20x = 40.03 - 6.75

3.20x = 33.28

Shifting 3.20 to Right Hand Side of the equation

x = 33.28 ÷ 3.20

Performing division on Right Hand Side of the equation

x = 8.76 miles

Thus, Lupita drove 8.76 miles.
