Answer:

A) d = 48t, d in miles, t in hours

B)d = 32t, d in miles, t in hours

C)y = 8 mph

Step-by-step explanation:

16 miles in 20 mins = 48 mph

16 miles in 30 mins = 32 mph

The boat speed is the average = (48 + 32)/2 = 40 mph

The current is the difference = 8 mph

Number 1.
Subtracting Negative Is The Same As Adding.
<span>So, It Would Be Equivalent  To A
</span>Number 2:
Subtracting From A Negative Is Making The Negative Number Larger.
<span>So, It Would Be A
</span>Number 3:
<span>Positive Plus Positive Makes Larger Positive:
37 + 13 = 50</span>.
<span>So, 3 Is D.
Number 4:
</span>Adding Negative Is Making Positive Numbers Smaller.
So, It Is C.
Number 5:
This Is C, Because -30 + 30 = 0 + 1 = 1

Answer:

2. ΔABC is isosceles

Step-by-step explanation:

Given : m∠A = 50

m∠BCD = 180 - (m∠BDC + m∠DBC)

              = 180 - (100 + 30)

              = 50

then

m∠A = m∠BCD

therefore ΔABC is isosceles

What is meant by the term outlier? What should you do with an outlier?
saul85 [17]

Outliers are data that are in a very far distance from other values in a set of data

Once an outlier is detected in a set of data, we can do the following to them:

  • Discard the outlier
  • Change the value of the outlier with another value within close range
  • Consider the distribution given

We may have a set of data where some of the <em>values are far in distance from the majority of the data</em>. The set of such data are known as an outlier.

For example, give the set of data;

  • 2, 4, 7, 45, 8

45 can be considered as an outlier since the <em>distance of data</em><em> to all other data is</em><em> large</em><em>.</em>

Once an outlier is detected in a set of data, we can do the following to them:

  • Discard the outlier
  • Change the value of the outlier with another value within close range
  • Consider the distribution given
