hi,
you must replace x by the number between parenthese.
I show you with the first one and let you do the second one
p(x) = 11x^5 -11x^4 - 5x^2 +15x-8
p(-4) = 11 (-4)^5 - 11 (-4)^4 -5(-4)² +15(-4) -8
p(-4) = 11 ( -1024- 256) - 5*16 -60-8
p(-4) = 11 ( -1280) -80-60-8
p(-4) = - 14080 - 148
p(-4) = - 14 228
Answer:
D because 0.75 in fraction form is 3/4 and 3/4 is greater then 2/3 which is the graphs rate of change.
Step-by-step explanation:
Answer:
$6
Step-by-step explanation:
Set up an equation:
88 = 8x + 6x + 4
Where x is the price of the shirts and pants
Subtract 4 on both sides:
88 = 8x + 6x + 4
-4 -4
84 = 8x + 6x
Combine Like Terms:
84 = 8x + 6x
84 = 14x
Divide by 14 on both sides:
84 = 14x
/14 /14
6 = x
Therefore, the price of each shirrt or pair of pants is $6.
Answer:
Student B's score has a greater variation from the mean than student A's score
Step-by-step explanation:
Student A : standard deviation = 5.4
Student B : standard deviation = 10.6
The standard deviation is used to measure the degree of variability of a measured value from the mean or average value of the set. The higher the value of standard deviation, the greater the variabilityabiut the mean. Hence for the question given above, Student B's score varies greatly from the mean Than student A's score.
