Answer:
0.2297453
Step-by-step explanation:
Given that :
Total faces of = 12 labeled 1 - 12
Probability of showing a 2 ;
P = required outcome / Total possible outcomes
P(showing a 2) = 1 /12
Hence, probability of not showing a 2 ;
P(showing a 2)' = 1 - 1/2 = 11/12
Probability that atleast one of 3 cubes shows a 2 :
1 - P(none of the cubes shows a 2)
P(none of the cubes shows a 2) =
(11/12 * 11/12 * 11/12) = 0.7702546
1 - 0.7702546 = 0.2297453
This question is based on the probability. Therefore, the probability that at least 1 show as a 2 is 0.22974 if 3 such number cubes are rolled.
Given:
In a certain board game a 12 sided number cube showing numbers 1-12 is rolled.
We need to determined the probability that at least 1 show as a 2, if 3 such number cubes are rolled.
It is given that total faces of = 12 labeled 1 - 12
Now calculating probability of showing a two ;
[tex]Probability = \dfrac{ Required\, outcome }{Total\, possible \,outcomes}[/tex]
[tex]Probability\, of\, showing\,a \,two=\dfrac{1}{12}[/tex]
Hence, probability of not showing a 2 is,
[tex]Probability\, of\, not\,showing\,a \,two=1-\dfrac{1}{12}[/tex]
Now, calculating probability that at least one of 3 cubes shows as a 2 =
1 - P(none of the cubes shows a 2)
[tex]P(none\, of\, the\, cubes\, shows\, a \,2) = \dfrac{11}{12} \times \dfrac{11}{12} \times \dfrac{11}{12} \\\\P(none\, of\, the\, cubes\, shows\, a \,2)=\dfrac{1331}{1728} = 0.770[/tex]
Probability that at least one of 3 cubes shows as a 2 = 1 - 0.770 = 0.22974
Therefore, the probability that at least 1 show as a 2 is 0.22974 if 3 such number cubes are rolled.

If a*b=(a-b)², calculate 2*5
I suppose * is supposed to denote a binary operation with the given definition,
a * b = (a - b)²
as opposed to multiplication, so that, for instance, 1 * 1 = (1 - 1)² = 0.
Using the definition of *, you have
2 * 5 = (2 - 5)² = (-3)² = 9
The expression 3h? + 4 represents the total amount of grain, in pounds, that is harvested
on a farm h hours into each workday. If the harvesting rate continues to follow this
model, which inequality represents the time, in hours, when the total amount of grain
harvested will be at most 100 pounds?
Answer:
B. [tex] 3h^2 + 4 \le 100 [/tex]
Step-by-step explanation:
total amount of grain, in pounds, harvested = [tex] 3h^2 + 4 [/tex], where, h = hours.
If at most 100 pounds will be harvested, it means the what will be harvested in pounds after working for some h hours, would be 100 pounds or less than 100 pounds. The highest is 100 pounds. "At most 100 pounds" means "less than or equal to 100 pounds".
The inequality that represents the time in hours would be:

Without graphing, find the slope of the line that goes through
1. (0,5) and (8,2).
2. (2,-1) and (6,1). 1/2
3. (-3,-2) and (-1,-5).
Answer:1/2,-3/2,-3/8
Step-by-step explanation:
The slope of the lines are -3/8, 1/2 and -7/2 respectively.
A linear equation is given by:
y = mx + b
Where y, x are variables, m is the slope of the line and b is the y intercept.
1) The slope (m) of the line that goes through (0,5) and (8,2). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{2-5}{8-0}\\\\m=-\frac{3}{8}[/tex]
2) The slope (m) of the line that goes through (2, -1) and (6,1). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{1-(-1)}{6-2}\\\\m=\frac{1}{2}[/tex]
3) The slope (m) of the line that goes through (-3, -2) and (-1, -5). is:
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{-5-2}{-1-(-3)}\\\\m=-\frac{7}{2}[/tex]
The slope of the lines are -3/8, 1/2 and -7/2 respectively.

Answer:
y = 6x + 4
Step-by-step explanation:
(x₁ , y₁) = (-2 , -8) & (x₂ , y₂) = (2 , 16)
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{16-[-8]}{2-[-2}\\\\=\frac{16+8}{2+2}\\\=\frac{24}{4}\\\\= 6[/tex]
m = 6
y - y₁ = m(x - x₁)
y - [-8] = 6(x -[2])
y + 8 = 6(x + 2)
y + 8 = 6x + 6*2
y + 8 = 6x + 12
y = 6x + 12 - 8
y = 6x + 4

700
61
6100
610
Answer:
The first number to subtract is 610
Step-by-step explanation:
In the division of 742 by 61, the first thing to do is to divide 742 by 61 straight and we get 10
So multiplying 10 by 61, we get 610
This is what we proceed to subtract from 742
So the first number to subtract is 610
