<h2>Answer:</h2>

In this exercise we have the following pattern:

1, -12, 12, -1

So we need to find the rule for this patter. First of all, let's take the first number, which is 1:

1

To find the second number, which is -12, we must subtract 13, because:

1 - 13 = -12

To find the third number, which is 12, we must add 24, because:

-12 + 24 = 12

In conclusion, the correct answer is A.) subtract 13, then add 24

blsea [12.9K]

Answer:

14.66 inches

Step-by-step explanation:

Calculation for How far does the tip of the minute hand move in 35 minutes

The tip of a minute hand will always travels at 360 degrees in an hour ( 60 minutes)

Hence, the tip of the minute hand

distance will be calculated using this formula

Circumference of a circle=2*π*Radius* Clock Tip hand movement/Number of minutes per hour

Let plug in the formula

Circumference of a circle==2*π*4 inches*35 minutes/60 minutes

Circumference of a circle= =2*π*4 inches*0.58333

Circumference of a circle==14.659 inches

Circumference of a circle==14.66 inches (Approximately)

Therefore How far does the tip of the minute hand move in 35 minutes will be 14.58 inches

Answer:

A manufacturer of banana chips would like to know whether its bag filling machine works correctly at the 447.0 gram setting.

So, Null hypothesis : H_0:\mu =447

It is believed that the machine is under filling the bags

So, Alternate hypothesis : H_a:\mu

n = 41

Population standard deviation = \sigma = 21

x = 443

We will use z test since n > 30 and we are given the population standard deviation.

Formula : z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}

z=\frac{443-447}{\frac{21}{\sqrt{41}}}

z=-1.2196

Use z table to find p value

p value = 0.1131

α = 0.02

p value > α

So, we fail to reject null hypothesis.

So, its bag filling machine works correctly at the 447.0 gram setting.
