Given that the first spinner has three equal sectors labelled 1, 2 and 3; and the second spinner has equal sectors labelled 3, 4, 5 and 6.
The number of possible outcomes that do not show a 1 on the first spinner is 2 (i.e. the first spinner shows 2 or 3).
The number of possible outcomes that the second spinner show the number 4 is 1 (i.e. the second spinner shows 4)
In probability, the word 'and' goes with multiplication.
Therefore, <span>the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner</span> is given by 2 x 1 = 2 possible outcomes.
i.e. the first spinner shows the number 2 and the second spinner shows the number 4 or the first spinner shows the number 3 and the second spinner shows the number 4.
0.38 if you divide 100 by 8 you get 0.125 and when you multiply it by 3 you get 0.375. 0.38>0.375

1: Almost all rocks are made of minerals but, different rocks have different kinds of minerals.
2: Sedimentary, metamorphic, and igneous.
3: Weathering is breaking down of the rocks, soil, and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and water.
4: i don't know this one sorry :(
5: Metamorphic Rocks
6: Geological Society
7: Igneous Rocks. They are about 3ft long!
8: Foliated Metamorphic Rocks
9:Phaneritic Igneous Rock
I hoped this helped! :) sorry for not knowing number 4 :( Have a good day! :)
Answer:
40
Step-by-step explanation:
so next year her money would be 6% more so:
5000 + (0.6 * 5000) = (1.06) * 5000
So each year she'll have : (1.06)*(last year's money)
So we can say after n years she will have :
((1.06)^n) * 5000
So:
5000((1.06)^n)=50000
n is 39.5
So around 40
