Answer:

164

Step-by-step explanation:

Checkpoint 2= -187

Checkpoint 1= -23

The negatives mean how much lower they are from the surface.

To find "how much lower," we need to subtract -23 from -187.

-187-(-23) is the same as -187+23 (2 negatives=1 positive)

-187+23= -164.

However, it's not negative in the answer because by asking how much lower, we don't need to have a negative. "How much lower" is a distance, and a distance is always positive.

Answer:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

$Mode= 53987$

$Median = \frac{52762+53108}{2}=52935$

$Midrange=\frac{50554+54364}{2}=52459$

Step-by-step explanation:

We can calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And if we replace the values given we got:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

The mode is the most repeated value and for this case with a frequency of 2 the mode is:

$Mode= 53987$

In order to find the median we need to order the dataset on increasing way like this:

50554, 51588, 52384 ,52584, 52762

53108, 53987 , 53987 , 54079, 54364

Since we have 10 values an even number the median is calculated from the average between positions 5 and 6 on the data ordered, and we got:

$Median = \frac{52762+53108}{2}=52935$

The mid range is defined like this:

$Midrange = \frac{Max +Min}{2}$

And if we replace we got:

$Midrange=\frac{50554+54364}{2}=52459$

Brian invests £4000 into his bank account.

GuDViN [60]

Answer:

10.24 years

Step-by-step explanation:

The computation of the time period is as follows:

As we know that

Amount = Principal × (1 + rate of interest)^time period

£8000 = £4000 × (1 + 0.07)^time period

£8,000 ÷ £4,000 = 1.07^time period

2 = 1.07^time period

Now apply the log to the both sides

log 2 ÷ log 1.07 = time period

= 10.24 years

Well you would divide distance by time and you should make sure that you do the trucks equation seperate from the cars equation other wise you would only get one answer and it looks like you need 2 so figure out the time an distance for each car then divide distance by time and that is your answer.
