Answer:

Hello your question is incomplete attached below is the complete question

answer : 192.15 pounds

Step-by-step explanation:

Given :

weight =  - 99.41 + 3.94*Height

R^2 = 0.81

SER = 10.2

<em><u>Determine the regression weight prediction</u></em>

Height of man = 74 inches

Hence : weight = - 99.41 + 3.94 * 74 = 192.15

therefore the regression weight prediction = 192.15 pounds

Which property of multiplication is shown by the equation 14 • y • 1 = 14y?
astra-53 [7]

Answer:

Multiplicative identity is the property shown by this equation

Step-by-step explanation:

Multiplicative identity is explained as the product of any number and one is that number. Multiplicative identity is a property exhibited by most of the mathematical tools.

Zero and one are the numbers used to simplify equations whereas zero is called the additive identity. If we add any number with zero, it will result in the same in number.

Like that 1 is used in multiplicative identity.  More simple example could be  5 ˣ 1 = 5 ., it is the multiplicative identity  property

SOLVE THIS ASAP and please show me the solving steps
GalinKa [24]

Answer:

45.2°

Step-by-step explanation:

a = 14

b = 11

c = 10

The Law of Cosines is given as:

arccos (a²+b²﹣c²/2ab)

In this above question, to find m

= arccos(11²+14²﹣10²/2·11·14)

= 45.20717°

Approximately = 45.2°

Option d is the correct answer

What’s the answer to this equation?
Tresset [83]

Answer:

Part A) The graph in the attached figure

Part B) see the explanation

Step-by-step explanation:

Part A) Graph the function

we have the quadratic function

y=3x^2-12x-36

This is a vertical parabola open upward

The vertex is a minimum

using a graphing tool

The graph in the attached figure

Part B) What are the values of a, b and c?

we know that

The values of a and b represent the x-intercepts of the quadratic equation

The x-intercepts are

(-2,0) and (6,0)

so

a=-2\\b=6

Find the value of c

we know that

The x-coordinate of the vertex in a vertical parabola is equal to the midpoint of the roots

so

The value of c is equal to

c=\frac{a+b}{2}

substitute the given values

c=\frac{-2+6}{2}=2

see the attached figure

I need ur smart brain power!!!!!
Andrej [43]

Answer:

y = -2x -3

Step-by-step explanation:

I love slope-intercept form! lol

y =mx +b

so we have 2 points given: (-1,5) and (4,-5)

to find the SLOPE of the slope-intercept form, we need to subtract and divide

(-5-5)/(4+1)

-10/5= -2 which is our slope

now! lets translate this info into point slope form. y - y1 = m (x - x1)

(-1,5) and we kno the slope is -2.

y - 5 = -2 (x - (-1))

y-5 = -2(x + 1)

y-5 = -2x -2

add five

y = -2x -3    we are back to slope intercept form! YAY!
