For each lettered part, a through c, examine the two given sets of numbers. without doing any calculations, decide which set has

romanna [79]

<span>Standard deviation shows the distribution present in a set. Range can be used to approximate this property. Therefore, Set b (100, 140, 150, 160, 200 10, 50, 60, 70, 110) has the largest standard deviation because it has a range of 190 (i.e. 200 - 10)</span>

7. Phozia has three pieces of rope with lengths of 160 cm, 192 cm and

lianna [129]

Answer:

a) 16 cm, b) 37 pieces

Step-by-step explanation:

Part a

Finding the largest divisor of 160, 192 and 240

160 divisors: 1, 2, 4, 5, 8, 10, 16, 32, 40, 80 and 160.

// You can alternatively find them by factor pairs, which are (1, 160), (2, 80), (4, 40), (5, 32), (8, 20) & (10, 16). This way is much more faster. Also, you can simply search them in metanumbers.com

192 divisors: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96 and 192

240 divisors: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120 and 240

The largest divider that they all have in common is 16.

So 16 cm is the largest possible length of each of the shorter pieces of

rope

Part b

Now we have to count how many 16 cm pieces of rope can we get from the large rope pieces, which lengths are 160 cm, 192 cm and 240 cm

160/16 + 192/16 + 240/16 = 10 + 12 + 15 = 37

The answer is 37 pieces

G(n) = 2n + 3<br> h(n)=n-1<br> Find (g•h)(n)

Tju [1.3M]

Answer:

Step-by-step explanation:

g(n) = 2n + 3

h(n) = n − 1

(g * h)(n) = g(h(n))

= g(n − 1)

= 2(n − 1) + 3

= 2n − 2 + 3

= 2n + 1

You oversee the community garden which has dimensions of 10 meters by 20 meters. You

motikmotik

Answer:

b.) Team A: 6 m

Team B: 8 m

Team C: 7 m

Step-by-step explanation:

The size of the plot Team A wants = 36 square meters

The size of the plot Team B wants = 64 square meters

The size of the plot Team C wants = 49 square meters

a. The outline of the garden is attached

b.) The dimensions of each side of the needed plot of land by the three teams

For team A we have;

The shape of the needed plot of land = Square

The size of the needed plot of land = 36 m²

The dimension of each side of the needed plot of land = 6 m

The dimensions of each side of the needed plot of land for team A = 6 m

For team B we have;

The shape of the needed plot of land = Square

The size of the needed plot of land = 64 m²

The dimensions of each side of the needed plot of land = 8 m

The dimensions of each side of the needed plot of land for team B= 8 m

For team C we have;

The shape of the needed plot of land = Square

The dimensions of the needed plot of land = 49 m²

The dimensions of each side of the needed plot of land for team C= 7 m

c.) The minimum dimension of the garden plot are;

Length: 15 m

Width: 13 m
