The sum of one third of a number and 2 1/3 is 9 find number

hammer [34]

Answer:

20

Step-by-step explanation:

The given relation can be written as the 2-step linear equation ...

(1/3)n +2 1/3 = 9

n +7 = 27 . . . . . . . . . step 1: multipy by 3 (makes the coefficient = 1)

n = 20 . . . . . . . . . . . step 2: subtract 7 (separates variable from constant)

The number is 20.

_____

Additional comment

Usually it is convenient to do the two steps in the opposite order: get the variable term by itself, then make its coefficient 1. Here, we chose the order we did because it eliminated fractions from the problem, which is often a step you'd like to do first.

Answer this will give 10 points

Travka [436]

Answer:

maximum --> 62

median --> 46.5

upper quartile --> 60

lower quartile --> 37

minimum --> 32

Step-by-step explanation:

Forgive me on the explanation as I'm a bit rusty on these types of problems.

First, we need to put the set of numbers in order -->

from: 34, 37, 39, 32, 48, 45, 53, 62, 58, 61, 60, 41 -->

to: 32, 34, 37, 39, 41, 45, 48, 53, 58, 60, 61, 62

maximum = biggest number => thus, 62

median = middle number in a sense => (45+48)/2 => thus, 46.5

upper quartile = median over the median => thus, 60

lower quartile = median under the median => thus, 37

minimum = lowest number => thus, 32

And there we have our 5 answers.

Hope this helps!

How you write 28% as a rate per 100

Digiron [165]

28% = 28 / 100

As a rate per 100 is: 28 per 100.

Geometry homework help!! Please!!

Answer:

∠A ≈ 66°

∠B ≈ 24°

AC ≈ 1.2

Step-by-step explanation:

SOH CAH TOA and the Pythagorean theorem are useful tools for solving right triangles. The first tells you ...

Sin = Opposite/Hypotenuse

For ∠A, that means ...

sin(A) = BC/AB = 2.7/2.95

The inverse sine function (sin⁻¹ or arcsin) is used to find the angle from its sine value, so ...

A = arcsin(2.7/2.95) ≈ 66°

Likewise, the ratio for angle B involves the adjacent side:

Cos = Adjacent/Hypotenuse

cos(B) = BC/AB = 2.7/2.95

B = arccos(2.7/2.95) ≈ 24°

Of course, angles A and B are complementary, so once you know angle A, you know that angle B is ...

∠B = 90° -∠A = 90° -66° = 24°

___

The Pythagorean theorem can be used to find the unknown side. It tells you ...

AB² = AC² + BC²

2.95² = AC² + 2.7²

AC = √(2.95² -2.7²) ≈ 1.2

___

These calculations are shown in the attachment using a TI-84 graphing calculator set to degrees mode. Any scientific or graphing calculator will do.

Before a new variety of frozen muffins is put on the market, it is subjected to extensive taste testing.People are asked to tast

Greeley [361]

Answer:

An experimental study

Step-by-step explanation:

An experiment deliberately imposes some treatment on individuals in order to observe their responses.

An experimental studies formulates some conditions in order to make an inference. An observational study tries to gather information without disturbing the scene they are observing.

This is then an experiment because people are deliberately asked to taste two muffins and asked for their response.
