I am sorry math is not my strong suit
Answer:
24.87
Step-by-step explanation:
23.87+1=24.87
boom you have your answer
Answer:
Please check the explanation.
Step-by-step explanation:
a)
As there are 1000000 units in 1 million
i.e.
1 million = 1000000 units
A house as purchases for $6780000.
Thus, the purchase price in million will be:
6780000/1000000 = 6.78 million
b)
purchase price in millions nearest to an integer
As the number we are rounding is followed by 7, so will be round the number up.
Therefore,
$6780000 rounded to the nearest million = $7,000,000
Por lo tanto, el valor de x e y es 5, 8.
<h3>¿Qué es el método de sustitución?</h3>
El método utilizado para resolver el sistema de ecuación, en este el valor de una variable se sustituye de una ecuación a otra para encontrar la solución.
Está dado
(x+1)/3 -(y-1)/2 = 1 -----1
7x -4(x+y) = 4 ------2
Resolviendo la segunda ecuación
7x -4x-4y = 4
3x -4y = 4
3x = 4+4y
x = (4+4y) / 3
Sustituyendo este valor en la ecuación 1
2(x+1) - 3(y-1) = 6
2x +2 -3y+3 = 6
2x -3y = 1
2(4+4y)/3 - 3y = 1
8 + 8y - 9y = 3
-y = -5
y = 5
x = 24/3 = 8
Por lo tanto, el valor de x e y es 5, 8.

Given: all selections are without replacement
Let D=event that chip is defective
N=event that chip is normal
note that D and N are complementary.
x=undefined event
(a) Second is defective
Probability for second chip to be defective
P(xD)=P(ND)+P(DD)
P(ND)=(80/100)*(20/99)=1600/9900
P(DD)=(20/100)*(19/99)=380/9900
=>
P(xD)=(1600+380)/9900=1980/9900=1/5
(b) All three are defective
P(DDD)=(20/100)*(19/99)*(18/98)=19/2695
Note: in probabilities, it is preferable to use the exact values (i.e. fractions).
