1/8 if they are numbered 1-8
250$÷5=50
each people 50
3 sister = 150
2 nephews = 100
spend 10$ to each sister
100$N - 30$spend =70$N
3S= (150$ + 30$ )
= 180$÷3
=60$
2N=70$÷3 =23.33$
Answer:
309^2 - 147^2 is the same as 95,481 - 21,609.
95,481 - 21,609 = 73,872.
Prime Factors of 73,872 =2, 2, 2, 2, 3, 3, 3, 3, 3, 19
Which is the same as = 24 x 35 x 19
<span>From the given data above, I used a scatter plot to present my graph using microsoft excel and added a trend line to get the line of best fit. The equation that I got is y = 2.3775x + 1.1011 and the r</span>² = 0.8922.<span>
</span>Part A: The temperature of the city is directly proportional with the number of people at the swimming pool because it showed an r² = 0.8922. Also, the line is linear with first degree.
<span>
Part B: You can make a line of best fit by:
</span>
<span>1. Plot your data in a
graphing paper or excel.
2. Make sure that your plotted data has a solid mark to indicate the points in
the graph.
3. Divide your data points by labeling x at the center, at the farthest part of
your line (left or right diagonally).
4. If you feel that the data are now finely divided, then construct a line base
on the x marks you're placing
5. Then you will notice how far or near your date points are by simply looking
at the points near the constructed line that you created.</span>
Answer:
Step-by-step explanation:
8^4 is the same as 8·8·8·8
The exponent 4 means that 8 will be multiply by itself four time.
