briefly describe the challenge that most african countries are facing​

Answer:

The authors found that, on average, a 1% reduction in the per capita GDP implies a 0.24 to 0.40 increase in infant mortality per 1,000 live births. In a more recent study, O’Hare et al.17 found effects of 0.33 for infant mortality and 0.28 for under-five mortality. These results are higher than those observed in the present study, which found an association of approximately 0.12 for infant mortality and 0.10 for under-five mortality rate for the total sample, and 0.15 and 0.14, respectively, for the subsample of low- and middle-income countries. This difference is probably due to the countries included in the sample, as Baird et al.14 and O’Hare et al.17 include only middle- and low-income countries in their analysis, while the present study included countries from the three income strata, with only 14% of the sample consisting of low-income countries. According to Maruthappu et al.6, the effect of economic crises on the health of children under five in the poorest countries is three-fold higher than the effect on children in high-income countries.

Answer:

The current amount of the Potassium-40 sample is approximately 37.521 grams.

Explanation:

The amount of the sample of the radioactive isotope decays exponentially in time, the amount of mass of the sample as a function of time ([tex]m (t)[/tex]), in grams, is described below:

[tex]m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)

Where:

[tex]m_{o}[/tex] - Initial mass, in grams.

[tex]t[/tex] - Time, in years.

[tex]\tau[/tex] - Time constant, in years.

The time constant can be found from half life ([tex]t_{1/2}[/tex]), in years, described in statement:

[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)

If we know that [tex]m_{o} = 300\,g[/tex], [tex]t = 3.9\times 10^{9}\,yr[/tex] and [tex]t_{1/2} = 1.3\times 10^{9}\,yr[/tex], then the current amount of the sample is:

[tex]\tau = \frac{1.3\times 10^{9}\,yr}{\ln 2}[/tex]

[tex]\tau \approx 1.876\times 10^{9}\,yr[/tex]

[tex]m = (300\,g)\cdot e^{-\frac{3.9\times 10^{9}\,yr}{1.876\times 10^{9}\,yr} }[/tex]

[tex]m\approx 37.521\,g[/tex]

The current amount of the Potassium-40 sample is approximately 37.521 grams.

Answer:

Since the 1930s the Middle East has emerged as the world's most important source of energy and the key to the stability of the global economy. This tumultuous region produces today 37% of the world's oil and 18% of its gas. When it comes to reserves, the Persian Gulf is king. --> MIDDLE EAST.

Russia, country that stretches over a vast expanse of eastern Europe and northern Asia. Once the preeminent republic of the Union of Soviet Socialist Republics (U.S.S.R.; commonly known as the Soviet Union), Russia became an independent country after the dissolution of the Soviet Union in December 1991. --> RUSSIA

Explanation:

SUMMARY UPDATED:

The middle east may be emerged as one of the most important source of energy to the world but Russia is one of the biggest places in the world although it is an independent country causing there to be more recourses from Russia compared to Middle East! The only difference here is that Middle East has been important since 1930s but Russia became independent form Soviet Union on 1991.

Answer:

-1/5

Explanation:

It is an established mathematical proof that the slope of line A perpendicular to another line B is the recoprovaknofokad

Hence the slope of B = the negative reciprocal of B

Given that ; lines s and t are perpendicular ;

Slope of S = 5 ;

The slope of T = - 1/5

Explanation:

The primary sector is the sector that has land as the main input

Therefore, the primary sector includes sectors such as the agricultural sector

The secondary sector, manufactures goods using raw materials for the goods being the produce of the primary sector, including crops such as cocoa, used to produce food drink, corn, barley, millet, and grapes used for making alcoholic beverages, wheat, used for making bread, and cotton

The tertiary sector, which is the service sector, includes the retailing, banking, hotels, restaurants, police, and service industries

Answer:

Mild weather.

Explanation:

Mild weather is the weather that labeled correctly because the regions nearer to the ocean or sea have mild weather condition. Due to near of water, the coastal regions experiencing warmer winters and cooler summers as compared to regions that are situated far from the ocean or sea. This is a result of ocean temperatures that taking longer to warm up and cool down than the adjacent landmass.
