Answer:
Step-by-step explanation:
A null hypothesis is a type of statement used in statistics that proposes that there is no difference between particular characteristics of a population whereas the alternative hypothesis proposes that there is a difference.
Let p be the population proportion of workers got their job through networking.
Given: 29% of workers got their job through networking.
i.e.
A researcher feels this percentage has changed.
i.e.
Hence, the required null and alternative hypotheses in symbolic form for this claim:
Answer:The height of the plant at the end of the end of the experiment. So it is the second one.
Step-by-step explanation:
Answer:
1231 ft
Step-by-step explanation:
Draw a right triangle. Label the height of the triangle. as 800 since the height of the triangle represents the height of the helicopter above the coast of the island. Label the base length of the triangle as d to represent the distance between the coast of the island and the coast of the mainland, P. The angle of depression from the helicopter to point P is 33° so draw a horizontal dotted line at the location of the helicopter and label the angle made by the horizontal line and the hypotenuse of the right triangle as 33°. The angle of elevation from P to the helicopter and the angle of depression from the helicopter to point P are congruent alternate interior angles so label the angle at P as 33°.
The side labeled 800 is opposite of P and the side labeled d is adjacent to P so you can use tangent to write an equation. Solve this equation for d and round to the nearest whole number.

He payed $43 to get the car so you need to do $111.20 -$43 = $68.20 then he pays $1.10 for every mile he drives so you need to decide $68.20 by$1.10 to get 62 so he drives 62 miles
