George traveled 300 miles in 8 hours. How far could he travel in 4 hours if he traveled at the same rate?

Amiraneli [1.4K]

Divide 300 by 8 to find the unit rate
300/8= 37.5

He travels 37.5 miles per hour

If he travels 37.5 miles per hour, to find the amount in 4 hours we would do 37.5 times 4

37.5×4=150

In 4 hours he travels 150 miles

In a random sample of 16 residents of the state of Washington, the mean waste recycled per person per day was 2.8 pounds with a

kakasveta [241]

Answer: The required confidence interval would be (2.72,2.89)

Step-by-step explanation:

Since we have given that

Mean = 2.8 pounds

Standard deviation = 0.24 pounds

n = sample size = 16

We need to find the 80% confidence interval for the mean waste.

z=1.341

So, the confidence interval will be

$\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=(2.8\pm 1.341\times \dfrac{0.24}{\sqrt{16}})\\\\=(2.8\pm 1.314\times 0.06)\\\\=(2.8-0.07884,2.8+0.07884)\\\\=(2.72116,2.87884)$

Hence, the required confidence interval would be (2.72,2.89)

X+y=5 x^y+y^x=17 solve for the value of y and x

pentagon [3]

X = 2
y = 3 

2 + 3 = 5 
2³ + 3² = 17 

------------------- 

BUT: 

x + y = 5 
x^y + y^ x = 17 

y = 5 - x
