Answer:

Step-by-step explanation:

1.33 and 1.3 are not the same, although they share the digits 1.3.

1.33 is accurate to the hundredths place, whereas 1.3 is accurate only to the tenths place.

So: 1.33 and 1.3 are in the same ball park, but are not the same.

PLEASE HELP AND SHOW WORK SIMPLIFY THIS RADICAL

Yakvenalex [24]

Answer:

x^2 | y^25 |√187x

Step-by-step explanation:

First you simplify the equation then you factor 184 into its prime factors which is 184 = 23 • 23

To simplify a square root, we extract factors which are squares, i.e., factors that are raised to an even exponent. Factors which will be extracted are: 4 = 22 Factors which will remain inside the root are: 46 = 2 • 23 To complete this part of the simplification we take the square root of the factors which are to be extracted. We do this by dividing their exponents by 2: 2 = 2 At the end of this step the partly simplified SQRT looks like this: 2 • sqrt (46x5y50) Rules for simplifing variables which may be raised to a power: (1) variables with no exponent stay inside the radical (2) variables raised to power 1 or (-1) stay inside the radical (3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples: (3.1) sqrt(x8)=x4 (3.2) sqrt(x-6)=x-3 (4) variables raised to an odd exponent which is >2 or <(-2) , examples: (4.1) sqrt(x5)=x2•sqrt(x) (4.2) sqrt(x-7)=x-3•sqrt(x-1) Applying these rules to our case we find out that SQRT(x5y50) = x2y25 • SQRT(x) sqrt (184x5y50) = 2 x2y25 • sqrt(46x)

A study was conducted on the relationship between speeds of cars and gas mileage. The correlation coefficient was 0.45. Later, t

True [87]

Answer:

0.45

Step-by-step explanation:

The correlation coefficient is used to measure the relationship between how two variables change. In this question, the two variables are cars speed and gas mileage. Since the speedometers were wrong as they were 5 mph too high in a constant manner, then the correlation between how changes in speed affect gas mileage will not be changed.

For example, if we are measuring how an increase of 15 mph decreased gas mileage, we are looking at the change in speed and it is the same if we start with 75 mph and then increase speed to 90 mph, or if we start with 45 mph and then increase to 60 mph. The change in speed for both cases will remain unchanged at 10 mph.

Now, since we have seen that the change in speed remains unchanged and since correlation coefficient is a measure of the relationship between how two variables change, then the new value of the correlation coefficient will remain the same as 0.45.

Write the equation in y=(your answer) y is the y axis in coordinate plane.

Vitek1552 [10]

Answer:

y = 4

Step-by-step explanation:

Given the equation of the line, y = 6, passing through point (3, 4):

By definition, parallel lines have the <u>same slope</u>.

The linear equation, y = 6 is a horizontal line with a zero slope. Therefore, the parallel line must also have the same slope = 0.

Plug the given values from the point (3, 4) into the slope-intercept form:

y = mx + b

where: y = 4, m = 0, and x = 3. We need to solve for the y-intercept, b:

y = mx + b

4 = 0(3) + b

4 = 0 + b

4 = b

Therefore, the y-intercept is (0, 4).

For horizontal lines, the y-coordinate = 4 stays the same, while having different x-coordinates.

Therefore, the equation that is parallel to y = 6 is y = 4.
