Answer:
1 ounce=28.3495 grams
60 ounces=60*28.3495=1700.97 grams
1 kilogram=1000 grams
1700.97/1000=1.70097 kilograms
Step-by-step explanation:
Answer: y = (-4/9)x2 + (16/9)x + (47/9)
Step-by-step explanation:
f(x) = a(x - h)2 + k, where the vertex is (h,k) = (2,7) while passing through the point (x,y) = (-1,3). We must plug everything in to solve for a first. Then,
3 = a(-1 - 2)2 + 7
3 = a(-3)2 + 7................Subtract 7 to both sides such that
-4 = 9a...............Then divide 9 such that
a = (-4/9)
Now we plug a into the equation with the vertex to create the parabolic function such that
y = (-4/9)(x - 2)2 + 7 ..............Then FOIL the (x-2)2 such that
y = (-4/9)(x2 - 4x + 4) + 7..............Then distribute the (-4/9) inside such that
y = (-4/9)x2 + (16/9)x - (16/9) + 7.............Then (-16/9) + 7 = (-16/9) + (63/9) = 47/9
so, y = (-4/9)x2 + (16/9)x + (47/9)
Answer:
11+4x
Step-by-step explanation:
2+3(x+3)+x
Distribute 3 through the parenthesis
2+3x+9+x
Add the numbers
11+3x+x
Collect thw like terms
11+4x
The answer would be 1 as it’d go 4 in each direction
Answer:
0.02 or 2%
Step-by-step explanation:
Theoretical probability calculated by dividing the number of events you want to calculate(green marble) with the total event possible(red + blue + green). There are 4 red marbles, 5 blue marbles, and 1 green marble. The probability will be: 1/(4+5+1)= 1/10= 10%
The result of the experiment is:
Red=22
Blue= 24
Green=4
Experimental probability calculated by dividing the number of events occurs with the total number of trials. We pull green 4 times and do 50x pulls, so the probability is: 4/50= 8%
Difference between the theoretical probability and the experimental probability is: 10%- 8%= 2%
