Answer:
20 times
Step-by-step explanation:
Given the following :
Probability of rolling a number less than 3 on a number cube:
Required outcome = (1, 2)
Total possible outcomes = (1, 2, 3, 4, 5, 6)
Required outcome / Total possible outcomes
= 2 /6
= 1/3
Hence, if number cube is rolled 60 times, number of times a number less than 3 is expected :
(Probability of obtaining a number less than 3 in one roll × number of rolls)
= (1 / 3) × 60
= 60 / 3
= 20 times
Answer:
-x-30
Step-by-step explanation:
<em>first you need to </em><em>distribute</em><em>:</em>
<em>3(x)+3(-6) -4(x)+ (-4)(3)</em>
<em>Then you </em><em>multiply:</em>
<em>3x+(-18)-4x+(-7)</em>
<em>then you </em><em>combine like terms:</em>
<em>3x-4x= -1x </em>
<em>-18+(-7)= -25</em>
<em>simplified:</em>
<u><em>-1x-30</em></u>

Use a calculator
Answer:
Step-by-step explanation:
Use this formula:
Where,
Substitute in the values.
Answer:
1st: volume = long x wide x high = 7 x [sqrt(25^2-7^2)] x 4 = 7 x 24 x 4 = 672
2nd: volume = area of base(circle) x high = pi x 9^2 x 8 = ~ 2035.8
3rd = volume = area of base(triangle) x high = [sqrt(3)/4] x 14^2 x 20 = ~1697.4
