Answer: The required expression would be

h + w - 11

Step-by-step explanation:

Here the given phrase,

The sum of a number h and a number w minus 11.

Since, Sum of h and w = h plus w = h + w

Also, the sign of minus is '-'

Therefore,

The sum of h and w minus 11 = h + w - 11

Which would be the required expression.

In order to test for the significance of a regression model involving 3 independent variables and 47 observations, the numerator

matrenka [14]

Answer:

The correct option is C

Step-by-step explanation:

From the question we are told that

The number of independent variables is $n = 3$

The number of observation is $z = 47$

Since n is are independent variables then their degree of freedom is 3

The denominator(i.e z) degrees of freedom is evaluated as

$Df(z) = z - (n +1)$

$Df(z) = 47 - (3 +1)$

$Df(z) = 43$

So for the numerator (n) the degree of freedom is Df(n) = 3

So for the denominator(i.e z) the degree of freedom is Df(z) = 43

What is the domain of the given function? {(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}

AlekseyPX

{(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}

(x, y)

Domain = x

Range = y

Domain = (3, 6, -1, 5, -4)

In case you need the range it is (-2, 1, 4, 9, 0).

Answer: (3, 6, -1, 5, -4)

Hope this Helps!!

I need help with this multiple choice question.

Neporo4naja [7]

Answer:

D. <em>XY > WY</em>

Step-by-step explanation:

The angles in a triangle add to equal 180°, so subtract 180°-55°-58° and 180°-64°-61° for the missing values of ∠WYX and ∠YXZ, respectively: ∠WYX = 67°, ∠YXZ = 55°.

The longest side of a triangle is opposite the largest angle, and the shortest side of a triangle is opposite the smallest angle:

In the triangle on the left, the shortest side must be XY because it is opposite the smallest angle, ∠W; the longest side is WX, which is opposite the largest angle, ∠WYX (67°).
In the triangle on the right, the shortest side is YZ, opposite the smallest angle, ∠YXZ (55°); the longest side is XZ, opposite the largest angle, ∠XYZ (64°)
