answer: y= 2x^2+2x-4
steps:
y= (2x+4)(x-1)
*FOIL method* y= (2x^2-2x+4x-4)
*simplify* y= 2x^2+2x-4
Answer:
360°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 4, hence
sum of interior angles = 180° × 2 = 360°
The slope is 3/4. you need to find the change of y over the change of x.
Answer:
3(3x^2 + 5)
Step-by-step explanation:
step 1: find out the greatest common factor (GCF) of the number 9 and 15
ex: 9x^2 + 15x (3 * 3x^2 + 3 * 5)
step 2: factor out the common term 3
ex: 3 * 3x^2 + 3 * 5 (3 * 3x^2 + 5)
step 3: simplify the equation
3 * 3x^2 + 5 [3(3x^2 + 5)]
Answer:
Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds
Step-by-step explanation:
Given that a very large number of college men were asked what they thought their ideal weight was.
A five number summary of the response (in pounds) follows:
Median 175
Quartiles 155 196
Extremes 123 225
This implies that 25th percentile is 155 and 75th percentile is 196
This can be interpreted as approximately 50% of men lie between 155 and 196 pounds.
Since 195 is very near to 195, we can say approximately
i.e. 41 difference = 50%
40 difference = 
Nearly 48.78% of the men gave a response that falls in the interval 155 to 195 pounds
