Answer:

Step-by-step explanation:

When an observer is at the same level with the submarine, his line of sight above the horizontal upward to the boat would form an angle called the angle of elevation.

Thus, the angle of elevation from the submarine to the boat is marked as <1. <1 is the angle of elevation from the submarine.

If the value of a real number x satisfies -2x + 5= -1, then what is the value of 5x

Nitella [24]

-2x + 5 = -1

subtract 5 from both sides: -2x = -6

divide each side by -2: x = 3

plug in 3: 5(3)

multiply: 15

the value of 5x is 15.

Answer:

C.It is a one-tailed test since the alternative hypothesis states that the parameter is greater than the hypothesized value.

Step-by-step explanation:

Let p be the percentage of students enrolled in an introductory Chemistry class dropped before the midterm. Then null and alternative hypotheses are:

$H_{0}$ : p=10%

$H_{a}$ : p>10%

The alternative hypothesis states that the parameter is greater than the hypothesized value.
