Answer:

16 feet of fencing

Step-by-step explanation:

This equation is essentially asking us the perimeter of the fence. If you add 5+3+5+3 you get the sum of 16

Answer:

16 feet

Step-by-step explanation:

She will need to the same amount of fencing as the measurement of her perimeter. To calculate the perimeter, you add length times 2 plus width times 2. 5x2+3x2=16, so the perimeter of the garden is 16 feet meaning she will need 16 feet of fencing :)

If possible step by step explanation. thank you!

Answer:

Step-by-step explanation:

$\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3$

$(3x^2)^\frac{1}{2} = 3^\frac{1}{2} x$

Remember that $\frac{x^b}{x^c} =$ x^(b-c)

Using that $\frac{3^\frac{1}{2}x }{3^\frac{1}{2} }$ =3^(1/2x-1/2)=3^((x-1)/2)

$3^\frac{x-1}{2} =3^1$

So we can say: $\frac{x-1}{2} =1$ , because the bases are the same

We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.

Given that x overbarequals3.6667, s Subscript xequals2.0656, y overbarequals4.2167, s Subscript yequals1.5613, and requalsne

Shtirlitz [24]

Answer:

$y = 0.7063x+2.7790$

Step-by-step explanation:

Given that

$x bar = 3.6667\\s_x= 2.0656\\y bar = 4.2167\\s_7 = 1.5613\\r = -0.9344$

We have slope of linear regression line is

$a=r*\frac{s_y}{s_x} =0.9344(\frac{1.5613}{2.0656} )\\=0.7063$

So regression line would be of the form

$y-4.2167 = 0.7063(x-2.0656)$ (since it passes through xbar, y bar)

$y = 0.7063x+2.7790$

is the equation of regression line.

A rental car agency charges $210.00 per week plus 0.25 per mile to rent a car. How many miles can you travel in one week for $34

Greeley [361]

Answer:

548 miles

Step-by-step explanation:

O.25m + 210 = 347

0.25m = 347 - 210

0.25m = 137

m = 137/0.25

m = 548
