When given a raw score, explain how to use the normal curve to compare that score to the population.

damaskus [11]

Assuming you know the mean (mu) and the standard deviation (sigma), you would use the raw score (x) to get the z score through this formula

z = (x-mu)/sigma

If you get a positive z value, then the raw score is above the mean. If z is negative, then the raw score is below the mean.

The absolute value of z tells us how far away from the mean we are in terms of standard deviation.

Eg: z = -3 leads to |z| = |-3| = 3, so we're 3 standard deviations below the mean.

Just need 5 and 6 done due in 20 minutes plz help

stealth61 [152]

Step-by-step explanation:

5. Let the equation of the line be y = mx + c

m = (6-15)/(2-(-1)) = -3

sub (2, 6) and m = -3:

6 = -3(2) + c

c = 12

Equation of the line: y = -3x + 12

6. Let the equation of the line be y = mx + c

y-intercept of 7 means c = 7

y = mx + 7

x-intercept: value of x when y = 0

therefore, sub (4, 0):

0 = m(4) + 7

m = -7/4

Equation of the line: y = -7/4x + 7

this is a topic on coordinate geometry. If you wish to explore more into this topic you can give me a follow on Instagram (learntionary) I'll be posting the notes for this topic soon and will also be posting other topics' notes and some tips :)

The table shows the weights of giant pumpkins grown in two towns, Cedartown and Baytown. Match each phrase to its value. Weight

Alexxandr [17]

Average and mean absolute deviation of pumpkins grown in Cedartown: 668.5; 60.4

Average and mean absolute deviation of pumpkins grown in Baytown: 628.5; 40.2

<h3>What is the Mean Absolute Deviation?</h3>

The average distance of each point from the mean of a data is the absolute mean deviation.

Mean and mean absolute deviation of pumpkins grown in Cedartown:

611, 753, 575, 685.5, 718

Average/Mean = (611 + 753 + 575 + 685.5 + 718)0/5

Average/mean = 3342.5/5 = 668.5

Mean absolute deviation = [(611 - 668.5) + ( 753 - 668.5) + ( 575 - 668.5) + ( 685.5 - 668.5) + ( 718 - 668.5)] / 5

Mean absolute deviation = [(57.5) + (84.5) + (93.5) + (17) + (49.5)]/5 = 302/5

Mean Absolute Deviation = 60.4

Mean and mean absolute deviation of pumpkins grown in Baytown:

584, 622, 713.5, 579, 644

Average/Mean = (584 + 622 + 713.5 + 579 + 644)/5

Average/mean = 3142.5/5 = 628.5

Mean absolute deviation = [(584 - 628.5) + ( 622 - 628.5) + ( 713.5 - 628.5) + ( 579 - 628.5) + ( 644 - 628.5)] / 5

Mean absolute deviation = [(44.5) + (6.5) + (85) + (49.5) + (15.5)]/5 = 201/5

Mean Absolute Deviation = 40.2
