Answer:

percentage error = 7.14%

Step-by-step explanation:

Hank's speedometer reads 60 miles per hour, but during a road test he finds the he was actually driving 56 mph.

estimated/ read value = 60 miles per hour

actual value/correct value = 56 miles per hour

error = estimated or read value - correct value/actual value

error = 60 - 56 = 4 mph

percentage error = error / correct value × 100

percentage error = 4/56 × 100

percentage error = 400/56

percentage error = 7.1428571429%

percentage error = 7.14%

Answer:

-6.6666666666667%

Step-by-step explanation:

Subtract the accepted value from the expiremental value

56 - 60/60 = -4/60

Divide the answer by the accepted value

-4/60 = -6.6666666666667%

Remove the negative symbol

6.6666666666667%, the answer is 6.6666666666667%

What can you predict regarding the probability of the
natka813 [3]

Answer:

The frequency does not change with more trials

Step-by-step explanation:

To predict: the probability of the coin landing heads up

Solution:

Probability refers to the chances that an event will occur in an experiment. The value of probability lies between 0 and 1. 0 indicates impossible event and 1 indicates a sure event. The probability of an event can not be greater than 1.

When a coin is tossed, there are two possible outcomes: heads (H), tails (T).

In case of the probability of the coin landing heads up, the frequency does not change with more trials.

How do you write in slope intercept with only the rate of change and one point. Like rate of change is -5 and the point is (3,0)
Simora [160]

Answer:

A linear equation in the slope-intercept form is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

Now, we know that the rate of change (the slope) is -5

Then we just replace a by -5

y = -5*x + b

Now we also know that this line passes through a point, and the point is (3, 0)

This means that the point (3, 0) is a solution for the line equation, so when x = 3, we also have y = 0.

Replacing these values in our equation we get:

0 = -5*3 + b

0 = -15 + b

15 = b

Now we know the value of b, so we can replace it in the line equation to get:

y = -5*a + 15

Which is the complete equation of the line.
