Answer:
b) Chemistry
Step-by-step explanation:
To compare both scored we need to standardize the scores using the following equation:
Where x is the score, m is the mean and s is the standard deviation. So, 82 on chemistry is equivalent to:
Because the mean of the scores on the chemistry final exam is equal to 75 and the standard deviation is 15
At the same way, 80 on Calculus is equivalent to:
Because the mean of the scores on the calculus final exam is equal to 83 and the standard deviation is 13
Now, we can compare the values. So, taking into account that -0.2308 is lower than 0.4667, we can said that the student do better in Chemistry.
Marked down 20% means it is selling for 80% of the original price ( 100% - 20% = 80%)
Multiply the original price by 80%
270 x 0.80 = $216.00
Slope = (7-2)/(3-0) = 5/3
slope intercept b = 2
equation y= 5/3x +b
<span>answer: B. y=5/3x + 2 </span>
if you mean 90 × 10⁴
then the answer would be, 900000.
but if you mean 9 × 10⁴ then the answer would be, 90000.
hope it helps.

Answer:
40°
Step-by-step explanation:
As clarified in an online document, a translation along a vector (which is a line in a plane) of a figure, is equivalent to a translation along a coordinate grid, and therefore, given that a translation is a form of rigid transformation, the the dimensions and inclinations of the rays forming the preimage are the same as those in the image and the angles measurement in the preimage and the image are equal.
Therefore, given that the angle measurement of the image is 40-degrees, the angle measurement of the image is also 40-degree (40°) angle.
