Answer:

A. 2/5

B. 1/10

Step-by-step explanation:

First off we need to calculate the probability that the chosen child is a girl So to calculate this probability, we have to know the num. of girls which is seen in the table. There are a total of 8 girls.

Therefore the probability of a girl being chosen is equivalent to the number of girls/exact number of children = 8/20 = 2/5 simplified.

Now to find the probability that the chosen girl is left-handed.

The amount of left-handed girls there is only 2. therefore the probability of selecting a left-handed girl will be 2/20 = 1/10 simplified.

Which sentence correctly compares the two points shown on the number line? -1 &gt; 0.25 , -1 &lt; -0.25, -0.25 &lt; -1
BartSMP [9]

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

A pile of sand has a weight of 90kg.
ankoles [38]

Answer:

9Kg, 18Kg and 63 Kg

Step-by-step explanation:

Sum the parts of the ratio, 1 + 2 + 7 = 10 parts

Divide the weight of sand by 10 to find the value of one part of the ratio

90 Kg ÷ 10 = 9 Kg ← value of 1 part of the ratio, thus

2 parts = 2 × 9 Kg = 18 Kg

7 parts = 7 × 9 Kg = 63 Kg

Thus the weights of each bag are 9 Kg, 18 Kg and 63 Kg
