Answer:

The deep body temperature of a healthy person is 310.15 K.

Step-by-step explanation:

Consider the provided information.

It is given that the deep body temperature of a healthy person is 37°C.

This can be written as:

T(°C)=37°C

To change Celsius into Kelvin use the formula.

T(K)= T(°C)+ 273.15

Now substitute the respective value in the above formula.

T(K)= 37+ 273.15

T(K)= 310.15 K

Hence, the deep body temperature of a healthy person is 310.15 K.

What are the zeros of the quadratic function f(x) = 2x2 + 8x – 3?

jenyasd209 [6]

Answer:

$x=-2-\sqrt{\dfrac{11}{2}}\ \text{and}\ x=-2+\sqrt{\dfrac{11}{2}}$

Step-by-step explanation:

My favorite way to go at this is to look at a graph. It shows the vertex at (-2, -11). Since the leading coefficient is 2, this means the roots are ...

$-2\pm\sqrt{\dfrac{11}{2}}$

where the 2 in the denominator of the radical is the leading coefficient.

You can also use other clues:

the axis of symmetry is -b/(2a) = -8/(2(2)) = -2, so answer choices C and D don't work
the single change in sign in the coefficients (+ + -) tells you there is one positive real root, so answer choice B doesn't work.

The first answer choice is the only one with values symmetrical about -2 and one of them positive.

You may be expected to use the quadratic formula:

$x=\dfrac{-b\pm\sqrt{b^-4ac}}{2a}=\dfrac{-8\pm\sqrt{8^2-4(2)(-3)}}{2(2)}\\\\=\dfrac{-8}{4}\pm\dfrac{\sqrt{88}}{4}=-2\pm\sqrt{\dfrac{11}{2}}$

Answer:

d) This is a completely randomized design with two explanatory variables (factors).

Step-by-step explanation:

Explanatory variables are independent variables.

In this case, I prepared two explanatory variables, which are : (i)30-second ad

(ii) 60-second ad,

Then, the explanatory variables were assigned to 4 treatment groups, and each variable is done once or thrice.

All subjects are assigned randomly to all treatment groups, with each treatment group seeing one. We can conclude that this is a completely randomized design with two explanatory variables.

Weiming, Farhan and Sam had some comic books.

mixas84 [53]

Answer:

Farhan had 9 comic books

Sam had 51 comic books and lived in his Mother's basement

Step-by-step explanation:

W + F = 36

W = 3F

3F + F = 36

F = 9

W = 27

S + F = 60

S + 9 = 60

S = 51
