Answer:
0.67038
Explanation:
One z-value is negative and the other is positive.
This means we are looking for area between the two given z-values on opposite sides of the mean.
From z-table attached, the area at z = -2.31 is 0.98956
Also, from the second z-table attached, the area at z = 0.47 is 0.68082
But since we are looking for the area between both z-scores, we will now have;
P(-2.31 < x < 0.47) = (0.98956 + 0.68082) - 1
P(-2.31 < x < 0.47) = 0.67038

The resultant vector is known to have made a 6.3-degree angle with the horizontal force, hence correct option is A.
<h3>How do you determine angle of the resultant vector ?</h3>
The resultant angle between the vectors is given by
θ = =
Note that the two forces are said to have the magnitude of 17.3 and 42.5 pounds hence, the angle of the resultant vector is known to be:
= (6.453/58.55)
= 6.2886 degree
= 6.3 degree.
Therefore, in the above scenario, the resultant vector makes a 6.3-degree angle with the horizontal<em> </em>force.
See full question below
Two forces of 17.3 pounds and 42.5 pounds act on a body with an angle of 21.9 degrees between them. The force of 42.5 pounds acts on the body in the horizontal direction. Choose the correct approximation for the direction angle the resultant vector makes with the horizontal force.
a. 6.3
b. 21.9
c. 15.7
d. 10.9

The solar system formed from an enormous cloud of dust and gas, called a nebula.
Fever 1973 by Laurie Anderson is based on the real outbreak of yellow fever. It is caused by the mosquito's bite displays the central idea of the story. Thus, option c is correct.
<h3>What is yellow fever?</h3>
Yellow fever is a viral infection that spreads because of a mosquito bite and results in fever, headache, body ache, and sometimes leads to organ failure and death.
Not all type of mosquito causes yellow fever but only the Aedes aegypti mosquito that breeds in clean water causes and transmits the virus from the infected to the normal person through the bite.
Therefore, option c. yellow fever is caused by the bite of a mosquito.
