You roll a standard number cube. What is the probability that you will roll an even number?

Mathematics

Answer:

The probability of rolling an even number would be \frac{1}{2} or 50%.

Step-by-step explanation:

A standard number cube has 6 sides that features numbers 1 to 6 on each side. Since there are three even numbers (2, 4, 6) total on the sides of the number cube, that means the theoretical probability of rolling an even number would be \frac{3}{6}, which simplifies to \frac{1}{2} or 50%.

F(x)=5<br> g(x)=sqrt x+2<br> find:<br> (f-g)(x)<br> (f • g(x)<br> (f/g)(x)<br> (f o g)(x)
Sergeeva-Olga [200]

f(x) = 5

g(x) = \sqrt{x + 2}

(f-g)(x) = 5 -  \sqrt{x + 2}

(f * g)(x) = 5(\sqrt{x + 2}) = 5\sqrt{x + 2}

(f/g)(x) = \frac{5}{\sqrt{x + 2}} = \frac{5\sqrt{x + 2}}{{x + 2}}

f(g(x)) = 5

Please help i need this answer in 5 min

Answer:6

Step-by-step explanation:

using BIDMAS: Brackets,Indices,division,multiplication,addition,subtraction.

1) Firstly you do the problem in the brackets. (-19 - -20) two negatives next to each other make a plus(+) meaning (-19 - -20) = (-19+20) which = 1

2) Next Step is to do the multiplication section. Since we got 1 in place instead of (-19 - -20) we multiply -3 by 1 which = -3.

3) Now the equation we have is 11 + -8 - -3. In BIDMAS both addition and subtraction are equal therefore we can do it in any order. 11 + -8 is the same as 11 - 8 = 3

4) The problem we have now is 3 - -3, like we said before two negatives next to each other make an addition sign(+) so 3 - -3 = 3+3 = 6, therefore getting the answer 6.

15 1/4 acres of land are divided into lots of at least 2/3 acres each. What is the maximum number of lots that can be created
alex41 [277]
We know that
15 1/4 acres-----------> (15*4+1)/4-----> 61/4 acres

[<span>number of lots]=(61/4)/(2/3)----> (61*3)/(4*2)---> 183/8----> 22.875 
22.785-----> 22 7/8

we know that
7/8--------> multiply by 3-------> 21/24
2/3-------> multiply by 8-------> 16/24
21/24-16/24-------> 5/24
so
22 7/8 is equals to--------> 22 21/24----> 22 (16/24+5/24)

t</span><span>he maximum number of lots that can be created are 22+1-----> 23 lots
</span><span>and there is a remnant of 5/24</span>
