Answer:
a) 0.70
b) 0.30
c) 12/45 =4/15
d) 2/45
Step-by-step explanation:
a) Prob of drawing a marble red or white = No of red and white marbles/total marbles
= 7/10 = 0.70
b) Prob of drawing a marble neither red nor white = 1-7/10 = 0.30
c) Prob of drawing two marble one red and one white at the same time
= 
d) Prob of drawing two marble one blue and orange white at the same time
= 
Step-by-step explanation:
what we trying to find the value of x and y
20x+6=y
x intercept,y=0
20x+6=0-6
20x/20=-6/20
×=-0.3
y intercept,x=0
20(0)+6=y
0+6=y
6=y
(-0.3,0)
19x+7=y
y intercept,x =0
19(0)+7=y
0+7=y
7=y
x intercept,y=0
19x+7=0-7
19x=-7
19x/19=-7/19
x=-0.37
To solve this problem you must apply the proccedure shown below:
1. You have that the forest fire covers 1600 acres at time t=0. the fire is growing at a rate of 9√t<span> acres per hour. Therefore, you have:
</span>
1600+∫(9√t)dt (from 0 to 16)
2. Then, when you solve it, you obtain:
1600+6t^3/2=1984
3. Therefore, as you can see, the answer is: 1984 acres.
Answer:
Side N: 20
Equation: 5 × 4 = 20
Step-by-step explanation:
Look at the other sides, and try to find a "pattern". Just by looking at the bottoms of the triangles, I saw 4 on BC and 16 on FG. I know that 4 times 4 equals 16, so that could be and option.
Now look at the left side. AB has a length of 3, and EF has a length of 12. I know that 3 times 4 is 12. Both times, there was an increase of 4 between the sides of the triangles.
Now, let's apply this to the last side. 5 times 4 is 20. So, the last side would be 20 on triangle EFG, and the equation would be 5 × 4 = 20.
