Correct Answer: D. North-Western

Correct Answer: C. 96,500 C

Correct Answer: D. \(\frac{13}{54}\)

Explanation

\(P(A)=\frac{1}{6},P(T)=\frac{1}{9}\)

Probability that only one of them will hit the target = \(P(A)\times P( \bar T ) + P( \bar A )\times P(T)\)

Where \(P( \bar T )\) is the probability that Tunde will not hit the target and \(P( \bar A )\) is the probability that Atta will not hit the target

\(P( \bar T )=1-\frac{1}{9}=\frac{8}{9}\)

\(P( \bar A )=1-\frac{1}{6}=\frac{5}{6}\)

Pr(only one) =\((\frac{1}{6}\times\frac{8}{9}) + (\frac{5}{6} \times \frac{1}{9}) =\frac{4}{27} + \frac{5}{54}\)

\(\therefore\) pr (only one) = \(\frac{13}{54}\)

Correct Answer: B. Merchandizing

Correct Answer: D) he felt unclean

Explanation

The question is asking about what Prophet Isaiah felt when he saw the glory of heaven. The options are: A) he was happy, B) he felt joyful, C) he worshipped God, D) he felt unclean (which is the correct answer).

Prophet Isaiah is one of the major prophets of the Old Testament. When he saw the glory of heaven, he became aware of his own unworthiness and sinfulness in comparison to the holiness of God. This caused him to feel unclean, which is why option D is the correct answer.

The feeling of being unclean is not just a physical sensation, but also a spiritual one. It is a recognition of one's own sinfulness and need for forgiveness, which is a common theme in Christianity. This experience also led Isaiah to confess his sins and seek forgiveness from God.

Overall, this question is testing your knowledge of Prophet Isaiah's experience when he saw the glory of heaven. It is important to understand the context and significance of this event in order to choose the correct answer.

(ii) Deforestation

(iii) Use of chemical, biological and nuclear warfare

(iv) Release of toxic waste

(v) Bush burning

(vi) Pollutants emitted from industrial activities

(vii) Pollutants emitted from mining and construction works

(b) physical changes that are likely to be associated with the increasing reduction of the ozone layer in the upper atmosphere

(i) As the ozone layer increases the amount of ultra-violet rays increases in the atmosphere

(ii) The increase in ultra-violet rays increases the amount of solar radiation at the earth's surface

(iii) Excessive ultra-violet rays leads to increase in skin cancer in man

(iv) Increased temperature leads to melting of polar ice and this leads to rise in sea levels.

(v) Possible increase in precipitation

(vi) Death of chlorophyll in plants leads to inability of plants to manufacture food.

Explanation

Using Lami's Theorem;

(a) \(\frac{T}{\sin 90^o} = \frac{120}{\sin 135^o}\) and T = 169.71N

(b) \(\frac{R}{\sin 135^o} = \frac{120}{\sin 135^o}\) and R = 120N
