Suppose the linear regression line y = 4.009x - 77.531 predicts a pizza

fredd [130]

Answer:

Option C, 1225

Step-by-step explanation:

y=4.009x-77.531

selling 325 pizzas, so x=325, now putting the value of x in the equation,

y=4.009×325-77.531

or, y=1225.394

y = 1225.394, which is the profit, if we approximate it to the nearest value, it's $1225

How do i convert 37/4 into mixed numbers

IrinaVladis [17]

How many times does (4) go into (37) ? 9 TIMES.

Remainder 1.

So as a mixed number would be 9 whole number, 1/4

= (9 1/4)

Trevor’s total employment compensation is $33,500. If Trevor has no job expenses and his gross pay is $28,600, then his total em

forsale [732]

X% of $28,600 is $33,500
x/100 * 28,600 = 33,500
x = 33,500 * 100 / 28,600
x = 117.13% = 117%

117% - 100% = 17%

The answer would be 17%.
Glad to help :)

F⃗ (x,y)=−yi⃗ +xj⃗ f→(x,y)=−yi→+xj→ and cc is the line segment from point p=(5,0)p=(5,0) to q=(0,2)q=(0,2). (a) find a vector pa

a. Parameterize $C$ by

$\vec r(t)=(1-t)(5\,\vec\imath)+t(2\,\vec\jmath)=(5-5t)\,\vec\imath+2t\,\vec\jmath$

with $0\le t\le1$ .

b/c. The line integral of $\vec F(x,y)=-y\,\vec\imath+x\,\vec\jmath$ over $C$ is

$\displaystyle\int_C\vec F(x,y)\cdot\mathrm d\vec r=\int_0^1\vec F(x(t),y(t))\cdot\frac{\mathrm d\vec r(t)}{\mathrm dt}\,\mathrm dt$

$=\displaystyle\int_0^1(-2t\,\vec\imath+(5-5t)\,\vec\jmath)\cdot(-5\,\vec\imath+2\,\vec\jmath)\,\mathrm dt$

$=\displaystyle\int_0^1(10t+(10-10t))\,\mathrm dt$

$=\displaystyle10\int_0^1\mathrm dt=\boxed{10}$

d. Notice that we can write the line integral as

$\displaystyle\int_C\vecF\cdot\mathrm d\vec r=\int_C(-y\,\mathrm dx+x\,\mathrm dy)$

By Green's theorem, the line integral is equivalent to

$\displaystyle\iint_D\left(\frac{\partial x}{\partial x}-\frac{\partial(-y)}{\partial y}\right)\,\mathrm dx\,\mathrm dy=2\iint_D\mathrm dx\,\mathrm dy$

where $D$ is the triangle bounded by $C$ , and this integral is simply twice the area of $D$ . $D$ is a right triangle with legs 2 and 5, so its area is 5 and the integral's value is 10.
