Answers

Answer:

son = 18 years old.

Step-by-step explanation:

Father to son = f/s = 7./3                Cross Multiply

3f = 7s

f + s = 60

f=60 - s

3(60-s)= 7s

180 - 3s = 7s

180 = 7s + 3s

180 = 10s

s = 180/10

s = 18

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

Answers

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.

A bicycle wheel has outer diameter 32cm. How far will the cyclist travel if the wheel rotates 100π times? Give your answer in kilometres and correct to two decimal places.

Answers

Answer:

[tex]T=0.3142km \\T=0.31km\ to\ 2dp[/tex]

Step-by-step explanation:

Diameter [tex]d=32cm=0.32m[/tex]

Number of rotations [tex]N=100\pi[/tex]

Generally the circumference of the wheel is mathematically given as

[tex]C=2\pi r[/tex]

[tex]C=2\pi (0.32)^2/4[/tex]

[tex]C=1.005309649m[/tex]

[tex]C=1.0m[/tex]

Generally the total distance traveled  T is mathematically given as

[tex]T=N*C[/tex]

[tex]T=100\pi *1m[/tex]

[tex]T=314.1592654m \approx 314.16m[/tex]

Total distance traveled  T in Kilometres

[tex]T=314.1592654m[/tex]

Which transformation was performed on PQRS to form P'QʻR'S'? (1 point)
1) A dilation factor of 2
2) A dilation factor of 4
3) A dilation factor of 1/2
4) A dilation factor of 1/4

Answers

Given:

A transformation was performed on PQRS to form P'QʻR'S'.

To find:

The transformation.

Solution:

The given graph shows two similar polygons. It means, dilation was performed.

From the given graph it is clear that,

[tex]PS=2[/tex] units

[tex]P'S'=1[/tex] units

Now,

[tex]\text{Scale factor}=\dfrac{P'S'}{PS}[/tex]

[tex]\text{Scale factor}=\dfrac{1}{2}[/tex]

A dilation factor of [tex]\dfrac{1}{2}[/tex] was performed on PQRS to form P'QʻR'S'.

Therefore, the correct option is (3).

Match the expression to its simplified form.
