You are testing two scales for accuracy by weighing two different objects.
Use the drop-down menus to complete the statements about the scales' accuracy.

Answers

Answer:

This is because the object on the 1st scale weighs (more) than the object on second scale, each pound of error results in a (lesser) percent error. The first scale was (10) pounds off the second scale,was (3) pounds off, so 1st scale was (10)% off 2nd scale was (12)% off.

Answer:

Because the object on Scale 1 weighs more than the object on Scale 2, each pound of error results in a lesser percent error. Scale 1 was 10 pounds off and Scale 2 was 3 pounds off, so Scale 1 was 10% off and Scale 2 was 12% off.

A baseball team has a 20-person roster. A batting order has nine people. How many different batting orders are there

Answers

Answer:

60,949,324,800

Step-by-step explanation:

We solve the above question using Permutation formula

The formula for Permutation =

nPr = n!/(n - r)!

Total Amount in a Set (n) = 20 persons

Amount in each Sub-Set (r) = 9 batting order

Hence:

20P9 = 20!/(20 - 9)!

= 60,949,324,800

Therefore, the different batting orders they would have are: 60,949,324,800

write the factors of the following expression x3 (2a‐6)+x2 (2a-6)​

Answers

Given:

The expression is

[tex]x^3(2x-6)+x^2(2x-6)[/tex]

To find:

The factors of the given expression.

Solution:

We have,

[tex]x^3(2x-6)+x^2(2x-6)[/tex]

First taking [tex](2x-6)[/tex] common, the given expression can be written as

[tex]=(2x-6)(x^3+x^2)[/tex]

Taking [tex]x^2[/tex] common from [tex](x^3+x^2)[/tex], we get

[tex]=x^2(2x-6)(x+1)[/tex]

Therefore, the factors of the given expression are [tex]x^2(2x-6)(x+1)[/tex].

which is greater -5/10 or -3 / -4​

Answers

Answer: -5/10, But that can be simplified to -1/2

-5/10 because it equals -1/2 with is gutter right in a number line than -3 or -4 (however if you made a typo and meant to say -3/4 the answer is still -5/10 BUT if you meant to say -3/-4 then the answer would be -3/-4 because that would equal +3/4 which would be further right)
