You have started keeping track of your spending habits. You have noticed that after 12 days you have
$1281 left in your account. You check again after 17 days have passed and your account is now at $861.
How many days will it take before you run out of money (assume you are spending money at a constant
rate)? Marks will be awarded only for the use of equations where t is the time elapsed in days and m is
the money left in your account in dollars.
Answers
Answer:
Time taken to elapse the remaining $861 = 10.25 days
Step-by-step explanation:
Assuming that I am spending at a rate of -x dollars per day
Let initial amount be A
The rate of expenditure = 1281-861/5 = 84 dollars per day
Time taken to elapse the remaining $861 = $861/$84 per day
= 10.25 days

If a point in the figure below is chosen at random, what is the probability that it is in the shaded region?
Answers
Answer:
254/324 which is about 78.4%
Step-by-step explanation:
found area of entire square to be 18² or 324
found area of 4-quarter circles - which equals one circle with radius of 9
A = 81π which is about 70
subtracted 324 and 70 to get 254
ratio of shaded to unshaded is 254 : 324
The Probability of point to lie is in the shaded region= [tex]\frac{254.34}{324}[/tex]
What is probability ?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Area of square= side x side
= 18 x 18
= 324 sq. cm.
Area of 4 quadrant =4 x [tex]\frac{\pi r^{2} }{4}[/tex]
= [tex]3.14 * 9 * 9}[/tex]
= 254.34 sq. cm.
So, probability that it is in the shaded region= [tex]\frac{254.34}{324}[/tex]

Aaron is a chocolate vendor. He finds that he needs 25 identical sweet boxes to pack all the chocolates he has if he puts 24 chocolates per box. How many sweet boxes will he need to pack all the chocolates, if he puts only 30 chocolates in a box?Immersive Reader (1 Point)
Answers
Answer: 20 boxes of chocolates
Step-by-step explanation:
First find out the total number of chocolates he has:
= 25 boxes * 24 chocolates per box
= 600 pieces of chocolate
The number of boxes needed if the chocolates are packed 30 in a box is:
= Total number of chocolates / Number of chocolates per box
= 600 / 30
= 20 boxes of chocolates

(a) In a scatterplot, the response is shown on the horizontal axis with the explanatory variable
on the vertical axis.
(b) If all of the data lie along a single line with nonzero slope, then the r
2 of the regression is
1. (Assume the values of the explanatory variable are not identical).
(c) If the correlation between the explanatory variable and the response is zero, then the slope
will also be zero.
(d) The use of a linear equation to describe the assocation between price and sales implies
that we expect equal differences in sales when comparing periods with prices $10 and $11
and periods with prices $20 and $21.
(e) The linear equation (estimated from a sequence of daily observerations):
Estimated shipments = b0 + 0.9*(Orders Processed) implies that we expect twice as many
shipments when the number of orders processed doubles only if b0 = 0.
(f) The intercept estimates how much the response changes on average with changes in the
predictor.
Answers
I'll do parts (a) through (c) to get you started
(a) False. The explanatory variable is always along the x axis, and the response variable is along the y axis. The response variable reacts to whatever the input explanatory variable is, hence the name "response".
---------
(b) True. If all data lie along a single straight line with nonzero slope, then either r = -1 or r = 1. If we have all data points on a line with some negative slope, then r = -1. If the regression slope is positive, then r = 1. Either way, it will lead to r^2 = 1 because (1)^2 = 1 and (-1)^2 = 1. In other words, there are two solutions to r^2 = 1 and they are r = -1 or r = 1. In the case of r = -1, we say the data has perfect negative linear correlation. With r = 1, the data has perfect positive linear correlation.
---------
(c) True. If r > 0, then we have some level of positive correlation which means the regression slope is positive in some way. If r < 0, then the regression slope is negative in some way. That must mean r = 0 leads to the regression slope having a flat horizontal line. This could mean one of two things: i) The points are all on or near the same curve such as a parabola, ii) The points are completely randomly scattered about. If case (i) happens, then it's better to use nonlinear regression instead of linear regression.

A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 1300 seats. The students filled 1001 of the seats in the theater. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answers
I like to use ratios and cross multiply for problems like this. Take the part (1001) over the whole (1300), and that equals x percent of 100 percent.
1001/1300 = x/100
100100 = 1300x

Tara uses 8.8 pints of white paint and blue paint to paint her bedroom walls. 4 5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer:
the blue paints of 1.76 pints is used to paint her bedroom walls
Step-by-step explanation:
Given that
Tara uses 8.8 pints of white paint
And, the 4 by 5 of this amount represent the white paint
We need to find out the number of paint used by the blue paint
So,
= 8.8 - (8.8 × 4 ÷ 5)
= 8.8 - 7.04
= 1.76 pints
Hence, the blue paints of 1.76 pints is used to paint her bedroom walls
