Answer:

B

Step-by-step explanation:

B because , it would be a straight line and it needs to cross x=-3. Its straight because there's no y. B is the only one that actually has -3 as x so B would be the only correct answer.

Answer:

the first one is 4 i think and the last one is 48 percent. im not sure if the dotted line is a underline tho

Step-by-step explanation:

:))

Multiply the numerator and the denominator by 100 to get 48/100

which is the same as 48% .

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Given,

Fraction = 12/25

To convert into percentage

divide the number by 100 and multiply by 100.

= ((12/25)×100)/100

= 12 × 100/25×100

= 48/100

= 48%

Hence, 48% is the expression of 12/25 as percent gotten by multiplying and dividing with 100.

Answer: the probability that two accidents will occur during the (five-day) work week is 0.0758

Step-by-step explanation:

Given that;

injuries in textile mill occur at the rate of 0.1 per day; λ = 0.1

probability that two accidents will occur during the (five-day) work week = ?

T= 5

so, the average number of on the job injuries for five days will be;

λT = 0.1 × 5

= 0.5

now if X follows Poisson distribution, hemce

P( X=k ) = [e^-λT (λT)^k] / k!

so the probability that two (2) accidents will occur during the (five-day) work week will be;

P( X=k ) = [e^-0.5 (0.5)²] / 2!

= (0.6065 × 0.25) / 2

= 0.1516/ 2

= 0.0758

the probability that two accidents will occur during the (five-day) work week is 0.0758

Answer:

x = 0

y = 2

Step-by-step explanation:

−6x + 6y = 6 −6x + 3y = −12

-6x+6x+6y-3y = 6

3y = 6

y = 2

checking:

6-6x+3.2 = -12

6-6x+6 = -12

12-6x = 12

x = 0

checking 2:

since x = 0 we ignore it and its multipliers from the equation:

6y=6+3y = 12

6.2 = 12 (check)

6+3.2 = 12

6+6 = 12 (check)

Answer:

The number of tennis players who finished above Eldrick are 20 players.

Step-by-step explanation:

Note: The question is not complete as the data in it are omitted. The complete question is therefore provided before answering the question as follows:

Eldrick finished at the 77th percentile of a men's tennis league with 88 players in it. How many tennis players finished above him?

The explanation of the answer is now given as follows:

The 77th percentile refers to the number of men's tennis league players below (inclusive) which 77% of the players can be found.

Therefore, we have:

Remaining percentile = 100th - 77th percentile = 23rd percentile

The remaining 23rd percentile refers to the number of men's tennis league players above (exclusive) which 23% of the players can be found.

Therefore, the number of tennis players who finished above Eldrick can be calculated as follows:

Number of tennis players who finished above Eldrick = 23% * Number of players in the league = 23 * 88 = 20.24

Rounding to a whole number, we have:

Number of tennis players who finished above Eldrick = 20
