Answer:

e. 0.0124

Step-by-step explanation:

Given that:

In a two-tailed hypothesis test, the test statistic is determined to be Z = -2.5

The p-value for this test can be determined from the Z tables at Z = -2.5

Using the EXCEL FUNCTION ( = NORMDIST (-2.5) )

Since the hypothesis is two-tailed, then;

The p-value = 2 × (= NORMDIST (-2.5))

The p-value = 2 × 0.00620

The p-value = 0.0124

The EXCEL FUNCTION computation can be seen in the attached file below.

Find expressions for the partial derivatives of the following functions:

nlexa [21]

Answer:

Step-by-step explanation: partial derivative is the differentiation of one variable e.g. X while leaving the values of the other variable e.g. Y

These four questions A, B, C and D have different functions separated by commas. I will not assume the commas to be something else like a plus sign.

A. f(x) = g'(x).k(y) , g'(x) + h(y)

f(y) = k'(y).g(x) , g(x) + h'(y)

B. f(x) = g'x (x+y)

f(y) = g'y (x+y) , h'y (y+z)

f(z) = h'z (y+z)

C. f(x) = f'x (xy) , f'x (zx)

f(y) = f'y (xy) , f'y (yz)

f(z) = f'z (yz) , f'z (zx)

D. f(x) = f'x (x) , g'(x) , h'x (x,y)

f(y) = h'x (x,y)

These are the partial derivative expressions for each variable in each function. You will need to pay a lot of attention to understand:

* while differentiating X alone, functions in Y which are separated by commas from the functions in X, are ignored totally because they are different questions

* In functions where X added to Y is in a bracket e.g. (x+y), to find the derivative of X, Y isn't thrown away because they are joined (by a plus sign) the derivative of X alone in this case would be f'x (x+y)

* f(x), just like g(x), simply means/represents a function in X hence f'(x) means the differentiation of all X-terms in that function

Name an equivalent ratio for 1/2 with a denominator of 20

Westkost [7]

To begin with, equivalent fractions represent the same part of a whole number. So I need to find a fraction, with a denominator of 20, that is the same value as 1/2:
1/2 = ?/20
1*10/2*10 = 10/20

Since the denominator needed to be 20, I multiplied the numerator and the denominator (1/2) by 10 to get 10/20. So, 1/2 and 10/20 are equivalent.

Help me please..........

aleksklad [387]

Answer:

66.4°

Step-by-step explanation:

→ Find the side which is not given

Hypotenuse = 15 cm

Opposite = ?

Adjacent = 6 cm

→ Utilise the formula triangle with out opposite in it

Cos⁻¹ = Adjacent ÷ Hypotenuse

→ Substitute in the terms

Cos⁻¹ = 6 ÷ 15 ⇔ 66.4°
