Express the following in standard form 178000000km

Mathematics
1 answer:
evablogger [386]2 years ago
8 0

Answer:

1.78 x 10^8

Step-by-step explanation:

178000000

I usually count the number of zeros first so in this case, it would be 6

178 x 10^6

This wouldn't be standard form because the number should be between 1 and 9

178 ÷ 100 = 1.78

I divided this number by 100 so I would times 10^6 by a 100

10^6 x 100 = 10^8

the answer would be 1.78 x 10^8

i hope this helps!

if it is confusing then i am sorry

What is the equation of the given line in standard form using integers coefficients y equals -1.7 x + 8.5
sukhopar [10]
If you want integer coefficients only, multiply the equation of the line by 10.  I'm assuming you accidentally left off the "= 0" at the end:  -1.7x + 8.5 = 0.

If that's the case, then  multiplying the whole equation by 10 results in -17x + 85 = 0.

Here you have only integer coefficients.

The variables A, B, and C represent polynomials where A = x + 1, B = x2 + 2x − 1, and C = 2x. What is AB + C in simplest form? x
mylen [45]

Answer:

If you would like to write a * b + c in simplest form, you can do this using the following steps:a = x + 1b = x^2 + 2x - 1c = 2xa * b + c = (x + 1) * (x^2 + 2x - 1) + 2x = x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x = x^3 + 3x^2 + 3x - 1The correct result would be x^3 + 3x^2 + 3x - 1.

G) Does your residual plot show that the linear model from the regression calculator is a good model? Explain your reasoning.
katrin [286]

The residual plot does not show a linear model and the estimated GPA of a student who studies for 15 hours a week is 3.17

<h3>How to interpret the residual plot?</h3>

The figure (1) represents the residual plot.

In the residual plot of a linear model, the line of the plot is represented by a horizontal line

From the figure, the line of the plot is not an horizontal line.

Hence, the residual plot does not show a linear model

<h3>The estimated GPA</h3>

The number of hours is given as:

x = 15 hours

The regression line is given as:

y = 0.134x + 1.16

Substitute 15 for x

y = 0.134 * 15 + 1.16

Evaluate

y =3.17

Hence, the estimated GPA of a student who studies for 15 hours a week is 3.17
