The number of girl child per family was recorded for 1000 families with 3 children. The data obtained was as follows: [2] Number

ira [324]

Answer:

$a.\ Probability = 0.426$

$b.\ Probability = 0.574$

Step-by-step explanation:

Given

$Total\ Families = 1000$

Number of Girls : 0 ----> 1 -----> 2 ------->3

Number of Families: 112 -> 314 --> 382 ---> 192

Solving (a): At most one girl

From the table, the number of families with at most one girl is: 112 + 314

i.e.

Number of Girls : 0 ----> 1

Number of Families: 112 -> 314

So, we have:

$At\ Most\ One\ Girl = 112 + 314$

$At\ Most\ One\ Girl = 426$

The probability is then calculated as:

$Probability = \frac{At\ Most\ One\ Girl}{Total}$

$Probability = \frac{426}{1000}$

$Probability = 0.426$

Solving (b): More girls

From the table, the number of families with more girl is: 382 + 192

i.e.

Number of Girls : -----> 2 ------->3

Number of Families: --> 382 ---> 192

So, we have:

$More\ Girls = 382 + 192$

$More\ Girls = 574$

The probability is then calculated as:

$Probability = \frac{More\ Girls}{Total}$

$Probability = \frac{574}{1000}$

$Probability = 0.574$

Please help with simplifying 2|-16.75|

klio [65]

First find the absolute value of -16.75. |-16.75|= 16.75

Then multiply that by 2. 16.75x2=33.5

So 2|-16.75| simplified is 33.5

1) 14 units2 2) 16 units2 3) 17 units2 4) 19 units2

horrorfan [7]

Answer:

<h2>4th option: 19 units2 </h2>

Step-by-step explanation:

<h3>The given figure can be divided as (i) upper rectangle, (ii) lower rectangle </h3>

Then,

(i) Breadth of upper rectangle = 2 units

Length of upper rectangle = 8 - 1 = 7 units

Therefore, 

Area of the upper rectangle = 7 × 2 = 14 units2

(ii) Breadth of lower rectangle = 1 unit

Length of lower rectangle = 5 units

Therefore, 

Area of the lower rectangle = 5 × 1 = 5 units2

Since,

Area of the figure is = Area of upper rectangle + Area of lower rectangle 

= 14 units2 + 5 units2

= 19 units2 (Ans) (4th option)
