Answer:
No he does not have enough walnuts
Step-by-step explanation:
So if one dozen cupcakes is 12 then two dozen is 24 and each one has 3 walnuts and he only has 56 walnuts then what you have to do is multiply 24 by 3 and get 72 so the answer is no he does not have enough
Answer:
No, in order to decorate 2 dozen cupcakes(24) he needs 72 walnuts. With 56 he can only decorate 18 cupcakes.

Problem: Suppose that on-the-job injuries in textile mill occur at the rate of 0.1 per day. What is the probability that two accidents will occur during the (five-day) work week
Answers
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
Eldrick finished at the percentile of a men's tennis league with players in it. How many tennis players finished above him
Answers
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

so when finding a parallel line both lines need to have the same slope, the slope of the line from the given equation is -2.
then we use the point slope formula to find the equation of the line that passes through (1,5).

−6x + 6y = 6 −6x + 3y = −12
Answers
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)

Multiply the numerator and the denominator by______ to get ---------
100
which is the same as ___%
Answers
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% .
What is percentage?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.
