Vitek1552 [10]

Full question:

A car's speed is 80 km/h. How far does it travel in a minute?

Answer and explanation:

1 hour = 60 minutes

Therefore if a car travels 80km in one hour, in one minute it would travel

80km/ 60 minutes = 1.333km

Therefore a car that travel 80km per hour would travel 1.333km per minute

Find the values of a and b that make the second expression equivalent to the first expression. Assume that x > 0 and y ≥ 0. S

mixas84 [53]

Answer:What was done from the first to the second equation was that the fraction was simplified. 126 and 32 have a common factors of 2.

126/32=(63*2)/(16*2)

The 2s in the top and bottom can cancel out, leaving the fraction 63/16.

In addition, since there are x terms on the top and bottom, they cancelled out as well.

x/x^3=1/x^2

This leaves an x^2 term on the bottom.

Thus, if a is 16, and b is 2, you will have an equivalent form of the fraction.

Graph the function y = 4 . Then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Elodia [21]

Given equation is y=4.

Question says to graph the given equation y=4 then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Equation y=4 has no "x" so that means line y=4 will be a horizontal line which passes through 4 on y-axis.

Since it is parallel to x-axis so that means there is no x-intercept.

y-intercept is (0,4) as the line crosses at 4 on y-axis.

Answer:

Y = 6.6406 + 0.2068x2 + 0.7995x3 - 3.607x4

Step-by-step explanation:

y 63 53 77 53 38 43 34 20 13

x1 45 42 40 37 27 24 20 14 12

x2 74 62 80 53 42 48 35 16 13

x3 H H L M H M L L M

For regression analysis : all variables must be quantitative ;

X3 variable may be represented as thus;

L = 1 ; M = 2 ; H = 3

Hence ;

X3 = 3 3 1 2 1 2 1 1 2

y= ____ + (____)x2+ (____)x3 + (____)x4

Using the online multiple regression calculator :

Y = 6.6406 + 0.2068x2 + 0.7995x3 - 3.607x4

From the general formular of a linear model:

y = w1x1 + w2x2 +... + wnxn + c = 0

Where c = intercept

w1,.. wn = weight of explanatory variable

Hence, the weights of x2 = 0.2068

Weight of x3 = 0.7995

Weight of x4 = - 3.607

Intercept = 6.6406
