Answer:
7.5
Step-by-step explanation:
So the constant proportionality is easy, it is the depindent veriable (how much it cost) divided by the independent veriable (how much fabric you have).
Put simply you know how much it will cost if you know how many yards you have. so if i have 2 yards i know it cost 15 dolars.
We could make a simple algebraic expretion that describes the proportionality.
C⁒y=7.5
So 7.5 is our constant, so if you know the cost or how many yards we have we always know what the other is.
So if i had 6.7 yards how much would it cost.
It would cost $50.25, what i did was i multiplied 6.7*7.5(our constant) and we got out cost c. Just to dubble check we can plug it in;
50.25⁒6.7 does=7.5 so it works.
Answer:
20) 2.084 meters
21) $75
22) 0.123 meters
23) 4 foot pieces
Step-by-step explanation:
20) divide the length by 4:
8.336 ÷ 4 = 2.084 meters
21) divide total cost by the amount of tickets:
39300 ÷ 524 = $75
22) subtract the smaller number from the greater number:
0.884 - 0.761 = 0.123 meters
23) the greatest common factor of 8 and 12 is 4, so he should cut each rope into 4 foot long pieces
Answer:
Answer: 1/3
Step-by-step explanation:
The probability of getting tails when tossing a coin is 1/2
The probability of rolling a number greater than 2 is 4 (3 4 5 6)
So 4/6 or 2/3 of the time is the probability of throwing the die and getting a number greater than 2.
The combined probability of getting both is 1/2 * 2/3 = 2/6 or 1/3
Answer:
a) Probability of no broken bats in a game P(X=0) = 0.3678
b) Probability of at-least broken bats in a game P(X≥2) = 0.2644
Step-by-step explanation:
we will use Poisson distribution
P(X=x) = e^(-λ) λ^ r/r!
a) Probability of no broken bats in a game P(X=0) = e^-1
= 0.3678
b) Probability of at-least two broken bats in a game
P(X≥2) = 1-([p(x=0)+P(x=1)]
= 1- (e^(-1)+e^(-1))
= 1-(0.3678+0.3678)
P(X≥2)= 1- 0.7356
P(X≥2)= 0.2644
There is supposed to be a graph with this question so I wouldn’t be able to answer
