The question is incomplete:
Reyna runs a textile company that manufactures T-shirts. The profit, p, made by the company is modeled by the function p
=
s^2+9s-142, where s is the number of T-shirts sold. How many T-shirts should be sold to earn a profit of more than $2,000?
Answer:
s>42
Reyna needs to sell more than 42 T-shirts.
Step-by-step explanation:
Given that you have to find the amount of T-shirts that should be sold to earn a profit of more than $2,000, you have to find the amount required to earn $2,000 by replacing p with 2,000 and solving for s:
s^2+9s-142=2000
s^2+9s-2142=0
(s+
)^2-2142-()^2=0
(s+)^2=2142+()^2
(s+)^2=2142+
(s+)^2=
s+=
s=
s=
s=
s=42
According to this, Reyna needs to sell more than 42 T-shirts to earn a profit of more than $2,000.
Find the mean, median and mode of these sets of data: a. 14,12,24,36,23 c. 2,3,4,5,30 b. 114,112,124,136,123 d. x, 2x,3x,4x,5x

Answer:
first u need to rearrange the three sets of data in ascending order
i'll just do a set here as an example
a: 12, 14, 23, 24, 36
Mean: (12+14+23+24+36)/5 = 21.8
Median: 23
Mode: 0 (as none of the datum is repetitive)
- 4.6 p - 6.3 p + 3.9 = -9.18
- 10.9 p + 3.9 = - 9.18
- 10.9 p = - 9.18 - 3.9
- 10.9 p = - 13.08
p = ( - 13.08 ) : ( - 10.9 )
Answer:
p = 1.2
Answer: 48
Step-by-step explanation: 10% of 480 would be 48 because your finding 10% of 480. for example: 10% of 100 would be ten because if you multiplied 10 times 10 it would be 100.
Area of a trapezoid = ((a+b)/2) * h
a = x + x
b = z + z
h = y
A = ((4 + 12)/2) * 6
A = ((16)/2) *6
A = 8 * 6
A = 48
answer is B
