Answer:

Option (1).

Step-by-step explanation:

In the figure attached,

Houses of three friends Jo, Boris and Carrie are located at the vertices of a triangle.

They want to meet at a place which equidistant from these vertices.

A point in a triangle which is equidistant from the vertices is its Circumcenter.

A circumcenter of a triangle is a point of intersection of perpendicular bisectors of its sides.

Therefore, the next step to find the meeting place should be,

Option (1). They should find the midpoint of the segments which connect their houses.

A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matc

swat32

Answer:

Step-by-step explanation:

Systolic. Calculate the mean

118+128+158+96+156+122+116+136+126+120+

=1276÷10 = 127.6.

To calculate the median arrange the values from the lowest to the highest.

96,116,118,120,122,126,128,136,156,158.

122+126+2=124.

Disastolic

80+76+74+52+90+88+58+64+72+82= 736÷10=73.6

To calculate the median arrange the values from the lowest to the highest.

52,58,64,72,74,76,80,82,88,90

Median= 74+76=150÷2=75.

Comparison

The Systolic and diastolic blood pressure measures different things, so comparing them is of no use.

It will be good if the relationship between the blood pressure can be investigated because the data are in pairs.

The population of a city, P, in millions, is a function of t, the number of years since 2010, so P=f(t). What does the statement

Crazy boy [7]

Answer:

$f(5) = 10$

The population of city is 10 millions in year 2015 that is 5 years after 2010.

Step-by-step explanation:

We are given the following information in the question:

The population of a city, P, in millions, is a function of t.

$P= f(t)$

where P is the population of city in millions and t is the number of years after 2010.

We have to interpret the meaning o the statement f(5) = 10.

$f(5) = 10$

Interpretation:

Comparing the relation we get,

It means that the population of city is 10 millions in year 2015 that is 5 years after 2010.

How much money needa to be deposited now into an account to obtain 9,000 in 7 years if the interest rate is 8% per year compound

Alex787 [66]

Answer:

P: the principal, the amount invested

A: the new balance

t: the time

r: the rate, (in decimal form)

Step-by-step explanation:

Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.

P = $1000, t = 2 years, r = 0.08.

A = 1000(1+0.08(2)) = 1000(1.16) = 1160

Triangle JKL is graphed on the coordinate plane below. On a coordinate plane, triangle J K L has points (1, 2), (4, 2), (3, 5).

lianna [129]

<u>Given</u>:

The coordinates of the triangle JKL are (1,2),(4,2) and (3,5)

We need to determine the coordinates of the triangle J'K'L' rotated 360° clockwise with the origin.

<u>Coordinates of the triangle J'K'L':</u>

The rule to rotate the triangle 360° clockwise with the origin is given by

$(x,y)\implies (x,y)$

The coordinates of the point J' is given by

$(1,2)\implies (1,2)$

The coordinates of the point K' is given by

$(4,2) \implies (4,2)$

The coordinates of the point L' is given by

$(3,5)\implies (3,5)$

Therefore, the coordinates of the triangle J'K'L' are (1,2), (4,2) and (3,5)

Hence, Option D is the correct answer.
