The ratio is 2:5 red beads to blue beads. If you have a TOTAL of 21 beads, how many are red, and how many are blue beads?

Answers

Answer:

Number of red beads = 6

Number of blue beads = 15

Step-by-step explanation:

Number of total beads = 21

Ratio of red beads to the blue beads = 2 : 5

Therefore, number of red beads I have = [tex]\frac{2}{2+5}(\text{Total number of beads})[/tex]

= [tex]\frac{2}{7}\times 21[/tex]

= 6 beads

Number of blue beads = [tex]\frac{5}{2+5}\times (21)[/tex]

= [tex]\frac{5}{7}\times 21[/tex]

= 15 beads

Therefore, number of red beads = 6

And number of blue beads = 15

Find the value of each variable.

It’s an isosceles triangle, so x would also equal 13, and now we just do the Pythagorean thrm

a^2+b^2=c^2

a=13 b=13

13^2+13^2= c^2

169+169= c^2

338= c^2 *square root both sides*

c= 18.38=y

A. 20
B. 15
C. 187
D. 13

Answers

Answer:

defective battery=200×1/13=15.3=15 is your answer

Number of expected defective batteries are option(B) 15

What is Probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given,

Probability that a battery is defective = [tex]\frac{1}{13}[/tex]

Total number of batteries = 200 batteries

Number of expected defective batteries = [tex]200(\frac{1}{13})[/tex] ≅15 batteries

Hence, the number of expected defective batteries are option (B) 15 batteries
