Answer:
P(-4,-8)
Step-by-step explanation:
Given two lines:
To determine the point of intersection P of the lines, we equate the two lines and solve for (x,y).
Therefore, the intersection point P of the lines is: P(-4,-8)
Answer:
First choice:
- <em><u>Most of the data in each plot are greater than 48.</u></em>
Explanation:
1. Boy's Heights.
Using the information you can create a frequency table:
Heigth Frequency
40 0
41 1
44 3
46 3
48 2
50 3
52 4
54 4
56 0
58 0
60 0
======
20 boys
2. Girl's Heights.
Similarly, create your frequency table:
Height Frequency
40 0
41 0
42 0
44 2
46 3
48 1
50 3
52 4
54 3
56 4
58 0
60 0
======
20 girls
<em>Which is a true statement for most of the data in each plot?</em>
<u><em>Most of the data in each plot are greater than 48.</em></u>
- Count the dots or add the frequencies from the tables.
- For boys, the frequency of points greater than 48 is: 3 + 4 + 4 = 11 which is more than half (there are 20 dots).
- For girls, the frequency of points greater than 48 is: 3 + 4 + 3 + 4 = 14, which is also more than half.
Hence, it is correct that most fo the data in each plot are greater than 48.
Answer: D. 9.4 units
Explanation: We use the Pythagoras theorem because we know that it’s a right triangle and we have 2 lengths.
8^2+5^2= c^2
89=c^2
c= sqrt 89
c≈9.4 units
By definition, supplementary angles are those whose sum is 180°
Therefore, ∠2 = 180 - ∠1
2x + 4 = 180 - 124
2x = 52
x = 26°
$1.87
60 cents in pennies = $.60
Each quarter is $.25, each dime is $.10, and each nickel is $.05.
1.87=q*.25+d*.10+n*.05+.60
