What is the Value of x?

Mathematics
1 answer:
Ulleksa [173]3 years ago
8 0

using the pythagorean theorem

a^2 +b^2 =c^2

x^2 + 8^2 = 15^2

x^2 +64 = 225

subtract 64 from each side

x^2 = 161

take the square root of each side

x =sqrt (161)

x=12.6886

Which statements correctly describe the data shown in the scatter plot?
Zepler [3.9K]

The correct options are:

A. The scatter plot has an outlier at (15, 2)

B. The scatter plot has a cluster with a range from 2 to 4

<u><em>Explanation</em></u>

Co ordinate of any point can be written in form of (x,y) where first value is the distance across x-axis and second value is the distance across y-axis.

We can see in the plot, that the outlier point is 15 unit across x-axis and then 2 unit across y axis from the origin. So the co ordinate of that point will be (15, 2).


Range means the values across the y-axis. We can see that the cluster starts at y=2 and ends at y=4. That means, the scatter plot has a cluster with a range from 2 to 4.

Hannah and Dawson have both invested money in savings accounts with APYs of 3.2%. If Hannah's account has a balance of $31,000 a
9966 [12]

Answer:

$341.07

Step-by-step explanation:

Hanna and Dawson both invested at 3.2% = 0.032

Hannah has balance of 31,000 in account

Dawson has balance of 42000 in account

Interests earned by both are

1)Hannah -P(1+i)^-n

=31000(1+0.032)^-1

=31000(1.032)^-1

=31000(0.968992)

=$30038.752

=$30038.75

Interest earned by Dawson is $31,000 - $30038.75 = $961.25

2)Dawson-  P(1+i)^-n

=42000(1+0.032)^-1

=42000(1.032)^-1

=42000(0.968992)

=$40697.664

=$$40697.664

Interest earned by Dawson is $42,000 - $40697.66= $1302.32

3) Hence the amount that Dawson earns than is:

=$1302.32-$961.25

= $341.07

This number is natural, whole, integer, and rational.

Whole numbers are numbers such as 0, 1, 2, ... This is a whole number.

Natural numbers can also be counting numbers.  They are the whole numbers, but starting at 1, not 0.  This is a natural number.

Integers are whole numbers with negatives.  This is an integer.

Rational numbers are any numbers that can be written as a fraction.  We can write this as 4563/1, so it is rational.
