Can one of you with these questions, ?

(13)

(47)

Or

(48)

Or

Step-by-step explanation:

(13)

we are given graph of f(x)

we can locate x=3 on graph

so, we get

(47)

we are given

Subtract both sides by 7

Or

Firstly, we will multiply both sides by 4

Subtract both sides by 14

now, we can locate it on number line

we get

(48)

we are given

Subtract both sides by 5

Divide both sides by 3

Or

Add both sides by 8

Divide both sides by -5

we get

now, we can draw on number line

and we get

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
