Answer:

10%

Step-by-step explanation:

Given:

Total number of racers = 270

Number of racers completed the race = 243

Number of racers gave up = 20

Now,

The number of racers who did not complete the race

= Total number of racers - Number of racers completed the race

= 270 - 243

= 27

Therefore,

The percentage of racers who did not complete the race

= \frac{\textup{number of racers who did not complete}}{\textup{Total number of racers}}\times100\%

= \frac{\textup{27}}{\textup{270}}\times100\%

= 10%

PLEASE HELP
Aleks04 [339]
Answer: 40%

=========================================

Work Shown:

"given that it's a senior" is an important piece of info that tells us to only focus on the "seniors" column. The word "given" is an indication that we know this information 100%

There are 5 seniors (2+3 = 5) and 2 of them are male. So 2/5 = 0.40 = 40% of the seniors are male. The probability of selecting a male, if we know this person is a senior, is 40%

masha68 [24]

Answer:

Brand X has to mix 8.4 oz of brand A mixed nuts which contain 35% peanuts and 12.6 oz of brand B mixed nuts which contain 25%, to obtain 21 oz. Bags of mixed nuts that contain 29% peanuts.

Step-by-step explanation:

Hi

We define

B_{A}=1oz @ 35\%, wich means Brand A has 1 oz containing 35% peanuts.

B_{B}=1oz @ 25\%, wich means Brand b has 1 oz containing 25% peanuts.

So we can build an equiation system

(1) B_{a}+B_{b}=21

(2)0.35 \times B_{a}+0.25 \times B_{b}=0.29 \times 21, after fixing it a little

(2)0.35B_{a}+0.25B_{b}=6.09

As we can use any method to solve the system, I used a calculator wich thrown the following results B_{a}=8.4 \ oz and B_{b}=12.6 \ oz.
