Based on the scatterplot and residual plot, is a linear
model appropriate for the growth of stock price?
A small technology company started offering shares of
stock to investors in 1987. At that time, the price of
one share of stock was $0.39. Since then, the
company has experienced rapid growth. Twenty-two
years later, the price of a single share of stock has
risen to over $110. The scatterplot shows the number
of years since the initial stock offering in 1987 and the
price of the stock.
O Alinear model is appropriate because the
regression line fits the scatterplot well.
O Alinear model is not appropriate because the
residual plot is centered about zero.
Alinear model is not appropriate because the
residual plot shows a clear pattern
Alinear model is not appropriate because the
scatterplot shows a clear pattern

Answer:
C
Step-by-step explanation:
These scatterplots show that model type A is best suited to summarize the relationship between year and stock price. The scatterplot of the processed data is nearly linear, so a linear model is suitable.
What is the Scatter plot?The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis.
A linear model is applicable if we can create a linear equation based on the connection between the independent and dependent variables (because there is no constant rate of change).
These scatterplots show that model type A is best suited to summarize the relationship between year and stock price. The scatterplot of the processed data is nearly linear, so a linear model is suitable.
Thus, despite its being curved, a linear model is adequate for this time and price scatterplot.

Damarcus and Xavier went to the arcade to play their two favorite games. Damarcus played 4 rounds of game 1 and 6 rounds of game 2 for $18.00. Xavier played 5 rounds of each game for $20. What is the cost of game 1? A. $1.00 B. $2.00 C. $3.00 D. $4.00
Answers
Answer:
The correct option is (c).
Step-by-step explanation:
Let x and y denote the cost of game 1 and game 2 respectively.
ATQ,
4x+6y = 18 ....(1)
5x + 5y = 20 ....(2)
Multiply equation (1) by 5 and equation (2) by 4.
20x+30y = 90 ....(3)
20x + 20y = 80 ....(4)
Subtracting equation (3) and (4)
20x+30y - (20x + 20y) = 90-80
20x-20x+30y-20y = 10
10y = 10
y = 1
Put the value of y in equation (1).
4x+6(1) = 18
4x = 18-6
4x = 12
x = 3
Hence, the cost of game 1 is $3.00

Answers
The ratio of apple trees to peach trees, if 3/7 of the trees are peaches is
4:3.
A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent.
Ratios compare two numbers, usually by dividing them. If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B.
We have been given that
In an orchard of apple and peach trees, 3/7 of the trees are peaches.
Find out
The ratio of apple trees to peach trees?
To simplify a ratio, divide each number in the ratio by the same amount. To fully simplify a ratio, divide each number in the ratio by their highest common factor. Always keep the numbers in the ratio as whole numbers.
Let the number of total trees in orchard is 7 i.e. denominator of fraction.
Then the no. of peaches tree are 3
so the no. of apple tree in the orchard = 4
Hence , If 3/7 of the trees are peach trees, the ratio of apple trees to peach trees is 4:3.

During the summer, Breanna works at a coffee shop. She saves 75% of her earnings to buy new school clothes. If Breanna earns $750, what is the best estimate for the amount of money she saves to buy clothes?
Answers
Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5
Step-by-step explanation:
Given: Breanna saves 75% of her earnings to buy new school clothes.
Earnings for Breanna = $ 750
The amount of money she saves to buy clothes = 75% of 750
= 0.75 x 750 [75%= 0.75]
= $ 562.5
Hence, the best estimate for the amount of money she saves to buy clothes = $ 562.5
