1. The average average height of a good is 142 cm theheightis 138 cm. what is the height of the other girls?
Jawab:
Penjelasan dengan langkah-langkah:
Diketahui :
Rata-rata tinggi perempuan = 142 cm
x₁ = tinggi perempuan pertama = 138 cm
Ditanya : x₂
Jawab :
Rata-rata
=> (x₁ + x₂ ) / 2 = 142
=> (138 + x₂ ) = 2 * 142 = 284
=> x₂ = 284 - 138 = 146 cm
Tinggi perempuan kedua = 146 cm
2. The total height of 5 children is 715 cm. What is the average height of each child?
[tex]m = \frac{ \rm{amount \: of \: data}}{ \rm{lots \: of \: data}} [/tex]
[tex]m = \frac{715}{5} [/tex]
[tex]m = 143[/tex]
So, the average height of each child is 143 cm.
3. the mean height of 4 children is 157.5 cm. if the 5th child enters this group, then the mean height will decrease 0.5 cm. how tall is the 5th child?
Bab Statistika
Matematika SD Kelas VI
(4 x 157.5) + a = (157.5 - 0.5) x 5
630 + a = 157 x 5
a = 785 - 630
a = 155 cmjawabnya 155.. tapi maaf ya kalo salah
4. The average age of the members in a family of five is 28. The average age of the three children is 14. What is the average age of the two adults?

7. the everage height of 6 student is 140 cm. If the one student is not counted, the average will be 145 cm. The height of the student that is not counted is .... cm
-Tinggi 6 orang
6×140
=840cm
-Tinggi 5 orang
5×145
=725cm
Tinggi satu orang tidak dihitung
840-725
=115cm
6 students x 140= 8405 students x 145= 725
6students heights-5 students height= 840-725= 115 cm
8. A ball is thrown vertically upwards and reaches its maximum height 2.0 s later a. What is the initial velocity of the ball? b. What is the maximum height that the ball reaches?
Jawaban:
a. 20m/s
b.20m
Penjelasan:
Given : Time taken to reach the maximum height t=2 s
a=−g=−10m/s ^2
The initial velocity of the ball can be calculated by,
Using v=u+at
∴ 0=u−10×2 ⟹u=20 m/s
Using S = ut + 1/2at^2
S = 20.2 + 1/2 (-10)(2)^2
S = 40 + (-20)
S = 20m (the maximum height)
9. The average height of 5 students was 148 cm. 2 more students whose averheight was 153 cm joined the 5 students. What was the average height of allthe students? Round off your answer to the nearest whole number
Jawab:
baik ynag diketahui adalah
Tinggi rata-rata 5 siswa adalah 148 cm.
2 lebih banyak siswa yang rata-rata tingginya 153 cm
bergabung dengan 5 siswa.
dan yang ditanya adalah
Berapa tinggi rata-rata semua
murid-murid?
penyelesaian
tinggi 5 siswa adalah 5 . 148 = 740
tinggi 2 siswa adalah 2 . 253 = 506
maka rata-rata tinggi 7 siswa adalah
= [tex]\frac{740+506}{7}[/tex]
= [tex]\frac{1246}{7}[/tex]
= 56
oke maka maka rata-rata tinggi 7 siswa adalah 56 cm
okee siap gan

10. the volume is 360cm3 the height is 5cm the width is 8cm, what is the length
Jawab:
9cm
Penjelasan dengan langkah-langkah:
Volume = Length x Width x Height
so, 360 = 8 x ? x 5
? = 360/(8x5)
= 360/40 = 9
Penjelasan dengan langkah-langkah:
V = Length ( L ) × Width ( W )× Height ( H )
360 = L × 8 × 5
360 = L × 40
360 : 40 = L
9 = L
So, the length of the block is 9 cm

13. A ball is thrown vertically upwards and reaches its maximum height 2.0 s later a. What is the initial velocity of the ball? b. What is the maximum height that the ball reaches?
Given : Time taken to reach the maximum height t=2 s
a=−g=−10m/s ^2
The initial velocity of the ball can be calculated by,
Using v=u+at
∴ 0=u−10×2 ⟹u=20 m/s
Using S = ut + 1/2at^2
S = 20.2 + 1/2 (-10)(2)^2
S = 40 + (-20)
S = 20m (the maximum height)
14. The average age of the members in a family of five is 28. The average age of the three children is 14. What is the average age of the two adults?
Jawab:
Penjelasan dengan langkah-langkah:
Suppose :
x = total age of all family members
y = total age of all children
z = total age of all adults
x/5 = 28
x = 28 (5)
x = 140
y/3 = 14
y = 14 (3)
y = 42
x = y + z
140 = 42 + z
z = 140 - 42
z = 98
The average age of the two adults = 98/2 = 49 years.
