Here is some information about 26 houses.a,b and c are all different numbers.Number of bedrooms:1,2,3,4,5.Number of houses:7,a,b

kkurt [141]

Answer:

$[a,b,c]=[4,2,5]$ or $[a,b,c]=[2,4,5]$

Step-by-step explanation:

Given

$\begin{array}{cccccc}{Bedroom} & {1} & {2} & {3} & {4} & {5} \ \\ {Houses} & {7} & {a} & {b} & {c} & {8} \ \end{array}$

$n = 26$

$Median = 3.5$

Required

Find a, b and c

Median is calculated as:

$Median = \frac{n+1}{2}$

$Median = \frac{26+1}{2}$

$Median = \frac{27}{2}$

$Median = 13.5th$

This means that the median is the average of the 13th and 14th item.

$\begin{array}{cccccc}{Bedroom} & {1} & {2} & {3} & {4} & {5} \ \\ {Houses} & {7} & {a} & {b} & {c} & {8} \ \end{array}$

Since the median is $Median = 3.5$ (average of 3 and 4),

and:

$3 \to b \to 13$

$4 \to c \to 14$

This implies that c begins at 14

So, the number of houses bedrooms 4 and 5 is:

$c + 8 = 26 - 14 +1$

$c + 8 = 13$

$c = 5$

Also

$7 + a + b + c + 8 = 26$ ---- sum of total frequency

$a + b + c = 26 - 7 - 8$

$a + b + c = 11$

Substitute $c = 5$

$a + b + 5 = 11$

$a + b = 11 - 5$

$a + b = 6$

Since a, b and c are different, then

a and b cannot be 5 because $c = 5$

a and b cannot be 3 because $a = b =3$

$b \ne 0$ because b ends at 13

So, possible sets are:

$[a,b]=[2,4]$

$[a,b]=[4,2]$

Include c, we have:

$[a,b,c]=[4,2,5]$ or $[a,b,c]=[2,4,5]$

Please help the question is in the picture.

Because thee dimensions of ΔRAH is twice as large as corresponding dimensions of ΔEAC,

|RA|=2|EA|=2*3.5=7

|AH|=2|AC|=2*6=12

So, we have that 2 corresponding sides are in proportion and angle between them =90⁰, so the angle between them are congruent,

we can use SAS to prove that these triangles are similar.

Carina spent a total of $5.27 buying a pineapple for $3.40 and some tomatoes that were on sale for $0.85 per pound. To determine

Neporo4naja [7]

Answer:

She subtracted 3.4 on the left and added 3.40 on the right

Step-by-step explanation:

3.40 + 0.85 x = 5.27

Subtract 3.40 from each side

3.40 -3.40+ 0.85 x = 5.27-3.40

.85x = 5.27 - 3.40

.85x =1.87

Divide by .85

.85x/.85 =1.87/.85

x = 2.2
