48.75 x 0.15 = $7.31
answer: tips are $7.31
Based on the data shown by the scatterplot on the distances in the solar system, a. an exponential model is appropriate because the scatterplot relating distance to temperature is curved.
<h3>Why is an exponential model appropriate?</h3>
The usage of the natural log to transform some of the variables resulted in the scatterplot of temperature v. distance ratio being curved.
As a result, a linear model cannot be used. The best model will therefore be an exponential model which is best for curves in a scatterplot.

The rate of interest applied on the amount is 15%.
According to the statement
we have given that the sum of money amounts to Rs. 2175 in 3 years and to Rs. 2625 in 5 years.
And we have to find the rate of interest on this money.
So, For this purpose,
The given equation is:
Money in 3 years = 2175
Money in 5 years = 2625
Amount increased in 2 years = 2625-2175
Amount increased in 2 years = 450
And amount increased per year = 450/2
Amount increased per year = 225.
SI in 3 years=450/2 *3=Rs. 675
Principal amount= 2175-675=1500
so again,
R=(I*100)/(P*T)
R=15%
So, The rate of interest applied on the amount is 15%.

Answer:
x=-5
Step-by-step explanation:
6x+3=5x-8 subtract 5x from both sides
x+3=-8x subtract 3 from both sides
x=-5
