The answer to "12x-(4y+7z) for x=9 y= 4 and z = 2" is 78.
Answer:
(6.2, 4.5)
Step-by-step explanation:
That point (P) will be the weighted average of the end points, where each weight is the proportion of the segment at the end farthest from the point:
P = (3A +1B)/(3+1)
= (3·7.5 +2.3, 3·4.2 +5.4)/4
= (24.8, 18)/4
= (6.2, 4.5)
Answer: ![\dfrac{x}{10}-y](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B10%7D-y)
Step-by-step explanation:
Given : A man earned x pesos in 10 days and spent y pesos during each of those days.
i.e. Total earning in 10 days = x
Earning per day =
[By unitary method] (1)
Money spent per day =y (2)
We know that
![\text{Savings = Money earned - Money spent}](https://tex.z-dn.net/?f=%5Ctext%7BSavings%20%3D%20Money%20earned%20-%20Money%20spent%7D)
i.e. Subtract (2) from (1), we get
![\text{Savings = }\dfrac{x}{10}-y](https://tex.z-dn.net/?f=%5Ctext%7BSavings%20%3D%20%7D%5Cdfrac%7Bx%7D%7B10%7D-y)
Hence, the expression to determine how many pesos he saved per day will be:-
![\dfrac{x}{10}-y](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7B10%7D-y)
Answer: 7/19
Step-by-step explanation:
Given that:
Probability of drawing 2 white cards without replacement = 14 / 95
Probability of drawing one white card = 2/5
Probability of drawing a second white card Given the first card is white will be :
P(2 white cards without replacement) = p(one white card) * p(second white card)
14 /95 = 2/5 * p
P = 14/95 ÷ 2/5
P= 14/95 * 5/2
P = 70 / 190
P = 7/ 19
