PLEASE HELP ASAP 40 PTS

Mathematics
1 answer:
DochEvi [55]3 years ago
7 0

Answer:

40 + 3x + 4 + 3x + 4 = 180

48+6x=180

48 - 48 + 6x = 180 -4 8

6x = 132

6x/6 = 132/6

x = 22

Step-by-step explanation:

1. since the triangle is isosceles, angles A and C will have the same measures, so to solve for x, you can add another 3x + 4 or you can multiply A by 2.

2. add like terms

3. subtract

4. divide to get x

50 is 40% of what number??????
kvv77 [185]
So a hack is we know that 20% times 5 =100% and 40 divided by 2=20 so

50=40%
divide both sides by 2
25=20%

20 times 5=100 so
multiply both sides by 5
125=100%

Lunna [17]

In a plot of the probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum occurs (A) at a0. the first Bohr radius.

<h3>What is an electron?</h3>
  • The electron is a subatomic particle with a negative one elementary charge electric charge.
  • Electrons are the first generation of the lepton particle family and are widely regarded as elementary particles due to the lack of known components or substructure.

Electron in the hydrogen:

  • Hydrogen has the simplest electron configuration to write because it just contains one electron.
  • There is essentially only one electron surrounding the Hydrogen nucleus.
  • Because hydrogen only has one electron, its configuration is 1s1.
  • The maximum occurs at a0, the first Bohr radius, in a plot showing the chance of finding the electron in the hydrogen ground state vs the distance from the nucleus.

Therefore, in a plot of the probability of finding the electron in the hydrogen ground state versus the distance from the nucleus, the maximum occurs (A) at a0. the first Bohr radius.

The marketing manager for an automobile manufacturer is interested in determining the proportion of new compact-car owners who w
pshichka [43]

Answer:

Two-tailed test.

Step-by-step explanation:

There are two types of tests:

One-tailed tests and two-tailed tests.

When we only test if the mean is less or more than a value, we have a one-tailed test.

When we test if the mean is different from a value, we have a two-tailed test.

If you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30, which test would you use?

Test if it is different, so a two-tailed test.
