What’s the difference in the range of temperatures recorded last year and the range of temperatures recorded two years ago
aksik [14]

Answer:

To find:

1. Range of temperature between two years

2. Modal temperature last year

3. Median temperature 2 years ago.

Solution:

1. Range is difference between the highest and lowest value.

Range of last year = highest value-lowest value

= 27-6 = 23

Range 2 years ago = highest value - lowest value

= 25-17 = 18

So, difference in range of temperature between two years = 23-18 = 5

2. Modal temperature last year = 11°C

(number that appears most frequently in the series arranged in numerical

order from smallest to largest)

3. Median temperature 2 years ago,

Median = middle number of the series.

Arrange numbers from lowest to highest. As this series contains even

numbers of entries, so median is average of middle numbers. So, (13+17)/2 = 15

What stage of genocide is "Propaganda surfaces: “Armenians are siding with the Turkish enemy (Russia)”. Intermarrying is forbidd
julia-pushkina [17]

Answer:

This is the second stage of genocide.

Explanation:

Once the first stage went on well, the second stage was waiting for implementation. Now that there was a clear distinction between the Turkish and Armenians in the eyes of the public, the government started with propaganda, using symbolization to vilify the Armenians and to give reason to the Turkish population to dislike or hate them.

This was done by spreading propaganda that the Armenians in Turkey are siding with Russia. Russia has been the biggest Turkish enemy for several centuries, so this immediately caused fear, insecurity, panic, and aggressive behavior from the Turkish population. In order to stop the spreading of Russia's influence through the Armenians, intermarrying became forbidden.
