Answer:

12.0

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the trig function relating the adjacent side of an angle in a right triangle to the hypotenuse:

Cos = Adjacent/Hypotenuse

Filling in the given values, we have ...

cos(24°) = 11/x

Multiplying this equation by x/cos(24°), we get ...

x = 11/cos(24°) ≈ 12.0

irga5000 [103]

To find the experimental probability, you will add the outcomes that resulted in even number and make that a ratio to the total number of outcomes.

(12 + 14 + 18)
(13 + 12 + 12 +14 + 11 + 18)

44/80 = 0.55
0.55 = 55%

The answer is choice D.

An atom has 24 protons and 12 neutrons what is the chemical symbol for the atom?

kykrilka [37]

Answer:

The element is Chromium.

Explanation:

The atom has 24 protons and 12 neutrons.

We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)

Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.

So, the atomic number is 24 and the atomic mass is (24+12)= 36

Therefore, the symbol is $\bold^{36} \mathrm{Cr}_{24}\bold$

goldenfox [79]

Answer:

Comparing means from dependent samples.

Step-by-step explanation:

In the scenario described above, the 25 sampled individuals were used to test the effect of weightlifting on alleviating back pain. The samples used were not changed nor altered during the study as the same subjects who were tested to measure their level of pain before lifting weight were the same group subjected to the actual weight lifting test and again had their level of pain tested. Since only one group was involved in the study ( a single group was tested on neutral and actual treatment). Hence, the study used dependent samples to compare the average level of pain.
