inysia [295]

Answer:

B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed.

Step-by-step explanation:

We make this conclusion based on these reasons:

We are told that the "null hypothesis was rejected" after the "manager feels that the pressure variability has changed., meaning the null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead.
"changes in the manufacturing process" form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.

It is based on the above reasons that the null hypothesis was rejected.

A balloon with a small leak loses 1% of its volume each day. If originally contains 24 liters of gas, what is the volume at the

Georgia [21]

ANSWER

The volume at the end of one week will be 22.32 liters.

EXPLANATION

If the balloon with a small leak loses 1% of its volume each day, then by the end of one week, it will lose 7℅ of its volume.

If the balloon originally contains 24 liters of gas, then this corresponds to 100%.

The volume at the end of one week will correspond to (100-7)%=93%

The volume at the end of one week is

$= \frac{93}{100} \times 24$

$= \frac{2232}{100}$
$= 22.32 \: liters$

A figure is shown Below Find M

yKpoI14uk [10]

Answer:

58 degrees

Step-by-step explanation:

We know that angles on a straight add up to 180 degrees. Therefore:

To find the angle at the top of the triangle do 180-112 = 68

To find the angle at the right side of the triangle do 180 - 126 = 54

We know that angles in a triangle add up to 180 degrees. Therefore:

To find m do 180 - (54 + 68) = 58
