Step-by-step explanation:
The average mortgage owed by Americans is $306,500, with a standard deviation of $24,500.
From the above information, we know that,
The population mean is

The population standard deviation is

Suppose a random sample of 150 Americans is selected

Since the sample size is quite large then according to the central limit theorem, the sample mean is approximately normally distributed.
The sample mean would be the same as the population mean that is

The sample standard deviation is given by

Where
is the population standard deviation and n is the sample size.

Therefore, the required parameters are:
1.

A = price of the desktop
b = price of the laptop
now, we know the laptop was more expensive than the desktop by 250 bucks, thus
b = a + 250.
for "a", he paid 8.5% in interest, for "b", he paid 5% in interest.
how much is 8.5% of a? well (8.5/100) * a, or
0.085a.
how much is 5% of b? well, (5/100) * b, or
0.05b.
now, we know the total charges for financing were $296, that means the interest paid in total was 296, thus whatever "a" or "b" are, we know that 0.085a + 0.05b = 296.

how much did the laptop cost? well, b = a + 250.

Answer:
The new points to the triangle will be:

Step-by-step explanation:
Because the reflection point is at
, all x values will subtract their distances from
to get their new values. The y values remain the same.
The starting values are:

Point
is 5 units away from
, so we'll subtract 5 from -1 to get the new x value:
, so
.
Point
is also 5 unit away from
, so we'll subtract 5 from -1 to get the new x value:
, so
.
Point
is 7 units away from
, so we'll subtract 7 from -1 to get the new x value:
, so
.

Step-by-step explanation:
The question asks to represent the position of two animals in a the cartesian coordinates plane. This is two perpendicular axis, the y-axis is the vertical one and the x-axis is the horizontal one. The animals are represented by dots, called a for the seagull and b for the shark.
Since the y-axis is the vertical axis and they ask to draw the points with a verical difference between them, we will draw the points in it.
Say the x-axis represents the sea surfice. The seagull would be over the sea, and the shark under the sea surfice (under x-axis).
This is the resulting drawing
