Answer:

Step-by-step explanation:

the median is the middle value of the list. first off, write the list of numbers in ascending order (small to big)

3, 4, 4, 5, 7, 7, 8, 10, 10, 10

since there are 10 values, there are two middle numbers which are 7 and 7. since they are both 7, the median is 7

The diagram shows rectangle ABCD, with diagnal BD. What is the perimeter of rectangle ABCS, to the nearest tenth?

Natalka [10]

Answer:

Perimeter of rectangle ABCD = 32.8 unit (Approx.)

Step-by-step explanation:

Given:

Hypotenuse BD = 12 unit

Angle θ = 30°

Find:

Perimeter of rectangle ABCD

Computation:

Using trigonometry function

Sin θ = Perpendicular / Hypotenuse

Sin 30 = CD / BD

0.5 = CD / 12

Length of CD = 6 unit

Cos θ = Base / Hypotenuse

Sin 30 = BC / BD

0.866 = BC / 12

Length of BC = 10.4 unit

Perimeter of rectangle ABCD = 2[Length + Width]

Perimeter of rectangle ABCD = 2[6 + 10.4]

Perimeter of rectangle ABCD = 2[16.4]

Perimeter of rectangle ABCD = 32.8 unit (Approx.)

is planning schedules for 30 students Sixteen students say they want to take French, 16 want to take Spanish, and 11 want to tak

ivann1987 [24]

Answer: There are 7 students who want French only.

Step-by-step explanation:

Since we have given that

Number of students is planning schedules = 30

Number of students who want to take French = 16

Number of students who want to take Spanish = 16

Number of students want to take Latin = 11

Number of students who take both French and latin = 5-3 =2

Number of students who take French and Latin and Spanish as well = 3

Number of students who only want Latin = 5

Number of students who only want spanish = 8

According to venn diagram, we get that

$a+b+g+f=16\\\\c+d+e+g=11\\\\b+e+f+g=16$

So, it becomes,

$c+d+e+g=11\\\\5+2+e+3=11\\\\e=11-(5+2+3)=1$

Similarly,

$b+e+f+g=16\\\\8+1+f+3=16\\\\12+e=16\\\\e=16-12\\\\e=4$

Similarly,

$a+d+g+f=16\\\\a+2+3+4=16\\\\a=16-(2+3+4)\\\\a=16-9\\\\a=7$

Hence, there are 7 students who want French only.
