Anne’s family drives to her uncle’s house for vacation, and they take two separate cars. anne’s car travels 383.5 miles between 10:15 am and 4:45 pm. the equation y = 58x represents the relationship between the distance, y, in miles and the time, x, in hours that anne’s sister’s car traveled. if both cars are traveling at constant rates, which car â€" anne’s or her sister’s â€" would you expect to arrive at their uncle’s house first? explain how you know.
Anne's family wouldn't have gotten there until about 5:55 pm.
How Distance is that?
Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.The arrival time is the travel time added to the start time. The travel time is given by ...
time = distance/speed
At 50 miles per hour, the travel time would be ...
time = 383.5/50 = 7.67 . . . . hours
The fraction of an hour is ...
(0.67 hours)×(60 min/hour) = 40.2 min
Adding the travel time to the start time, we get an arrival time of ...
10:15 am + 7:40 = 17:55 = 5:55 pm
Anne's family wouldn't have gotten there until about 5:55 pm.

The width and the length of the rectangle are equal to 6√5 units and 3√5 units, respectively.
What are the dimensions of the rectangle?
In this problem we find the area of the rectangle and the ratio of the length to the width of the figure. Mathematically speaking, the area of the rectangle is described by the following formula:
A = (2 · x) · x
A = 2 · x²
If the area of the rectangle is equal to 90 square units, then the width of the rectangle is:
2 · x² = 90
x² = 45
x² = 3² × 5
x = 3√5
The width of the rectangle is equal to 3√5 units. By the given ratio, the length of the rectangle is equal to 6√5 units.
Therefore, the length and width of the rectangle are equal to 6√5 units and 3√5 units, respectively.

The graph of g(x) is wider than f(x) and is shifted to the right 3 units and down 3 units.
Answer: The graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 units.
Step-by-step explanation: I took the quiz and got it right
The function f(x) = x² is transformed and became g(x) = 3(x+2)² -1 has the graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 unit.
What are graph transformations ?By applying suitable graph transformation we can shift, stretch, shrink, a given graph along x and y axis.
According to the given question given a graph f(x) = x² and g(x) is 3(x+3)² - 3.
Let us break transformations of g(x) one by one.
g(x) = 3f(x) which implies it's amplitude or vertical stretch is increased by a factor of 3.
Now, g(x) = 3(x+3)² implies the graph is shifted towards left by 3 units as x + 3 = 0 is x = -3.
Now, g(x) = 3(x+3)² - 3 implies that the whole graph has been shifted 3 units down along the y axis.
Hence the graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 units.

Differences between two samples are least likely to be statistically significant if the samples are _____ and the standard deviations of the samples are _____.
If the samples are large and the standard deviations are small, the differences between the two samples are least likely to be statistically significant.
How does standard deviation work?The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
Why is statistical significance important?"Statistical significance precision" tells us, in Redman's words, "whether a result is probably caused by chance via some factor of interest." A significant finding simply means that you should consider it. can be sure that it is true and not that you were just lucky (or unlucky) in the sample you chose.

A regular polygon's perimeter is equal to the product of all of its sides, which is equal to the number of sides times the length of a side.
We use the general method to get the perimeter of an irregular shape since the sides of an irregular polygon might not all be the same length.

A 2-lb sample of an unknown liquid occupies a volume of 47.6 in.3 for the liquid determine (a) the specific volume, in ft3/lb, and (b) the density, in lb/ft3.
The specific volume is 0.0135 ft^3
The density is 74.07 lb/ft^3
Here,
A 2-lb sample of an unknown liquid occupies a volume of 47.6 in^3.
We have to find the specific volume and density.
What is Specific volume?
Volume is a measure of the amount of space occupied by an object.
Now,
Mass = 2 lb
Volume = 47.6 in^3
= 0.027 ft^3
Hence, Specific volume = volume/ mass = 0.027/2 = 0.0135 ft^3
And, Density = mass/ volume = 2/ 0.027 = 74.07 lb/ft^3
So, The specific volume is 0.0135 ft^3
The density is 74.07 lb/ft^3
