If you would like to find the solution to the system of equations, you can do this using the following steps:
2x = 5y + 4 ... 2x - 5y = 4 /*(-3)
3x - 2y = -16 /*2
_____________
-6x + 15y = -12
6x - 4y = -32
_____________
-6x + 15y + 6x - 4y = -12 - 32
11y = -44 /11
y = - 44/11
y = -4
<span>2x = 5y + 4
</span>2x = 5 * (-4) + 4 = -20 + 4 = -16
2x = -16
x = -16/2
x = -8
(x, y) = (-8, -4)
The correct result would be (<span>-8, -4</span>).
I think it's Ten thousandths, zero eighty-eight.
I'm not too sure on this, but hopefully i helped you.
Answer:
62.5 miles
Step-by-step explanation:
The answer is 62.5 miles because 5 divided by 8 is 0.625 and 0.625 multiplied by 100 is 62.5
Answer:
The claimed proportion (population) is
![p=0.11](https://tex.z-dn.net/?f=p%3D0.11)
The sample proportion (p-hat) is
![\hat{p}=0.10](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D0.10)
Step-by-step explanation:
In the population, we have the parameter p that is 11%.
![p=0.11](https://tex.z-dn.net/?f=p%3D0.11)
Then, a sample of n=160 is taken and the proportion of the sample is 0.10.
![\hat{p}=0.10](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D0.10)
The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.
Answer:
Sue would have taken 15 hours to sew all the costumes.
Step-by-step explanation:
In 10 hours, Sue sewed 5 costumes (1 every 2 hours).
Sue= 5 costumes
Sue sewed in 10 hours, twice as many costumes as Anne in 16 hours. Then 5 is twice costumes than Anne produced. Therefore, Anne sewed 2.5 costumes.
Anne: 2.5 costumes
In total they had to sew 5+2.5= 7.5 costumes. Then Sue would have taken 7.5*2= 15 hours to sew them all.
