Step-by-step explanation:
r u adding them or not if so it will be 2 years:0 months
Arranging from least to greatest the given data for the temperatures for the last nine days of February,
39, 43, 44, 44, 45, 49, 49, 50, 51
The minimum is 39 and the maximum is 51. Then, for the median, the answer would be 45. Dividing the entries by 4. The lower quartile (Q1) is 43. Thus, the answer is letter B.
<span>Given
number : 14 - 6x / 19
So we need to write this fraction as a sum or difference.
First, simplify the given number:
=> 14 – 6x / 19
=> <u>14 x 19 – (6x</u>)
19
=> <u>266 – 6x</u>
19
=> 266 – 6x = -2 * (3x - 133)
Thus, the final result would be:
=> <u>-2 * (3x - 133) </u> => This
will be the fraction sum or difference of the given number<u>
</u> 19

Uh I think it’s 3? 10-7=3
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+![\frac{81}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B81%7D%7B4%7D)
(s+
)^2=![\frac{8649}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B8649%7D%7B4%7D)
![\sqrt{(s+\frac{9}{2})^2 } =\sqrt{\frac{8649}{4} }](https://tex.z-dn.net/?f=%5Csqrt%7B%28s%2B%5Cfrac%7B9%7D%7B2%7D%29%5E2%20%7D%20%3D%5Csqrt%7B%5Cfrac%7B8649%7D%7B4%7D%20%7D)

s=![\frac{93}{2}- \frac{9}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B93%7D%7B2%7D-%20%5Cfrac%7B9%7D%7B2%7D)

s=42
According to this, Reyna needs to sell more than 42 T-shirts to earn a profit of more than $2,000.
