Help and explanation with this probability question would be really appreciated :)

Mathematics
1 answer:
GuDViN [60]3 years ago
3 0

Answer:

b

Step-by-step explanation:

The probability (PB) is .4 or 4/10 or 2/5.

So, we'd do a proportion.

2/5=x/6

Cross multiply.

5x=12

Divide by sides by 5.

x=2.4

We round up to account for the .4

so b

I can't answer c right now, but I'll come back once my class is over :)

Tanzania [10]

Answer:

4/9

Step-by-step explanation:

Given rate is 1/3 acre per 3/4 hours.

To calculate the rate per hour, we have to divide total acres by the fraction of hour

=> \frac{\frac{1}{3} }{\frac{3}{4} }

=> \frac{4}{3*3}

Use the grouping method to factor x3 + x2 + 3x + 3
Alex

Answer:

8x +3

Step-by-step explanation:

Just collect the like terms, like terms have the same variable. So in this case, 2x, 3x, 3x all share the variable x, so we can add it together.

So when simplified:

2x +3x + 3x+ 3 = 8x +3

Hope this helped,

How to find the number of sides of a polygon when given the interior angle sum
wariber [46]

Given:

Sum of interior angle

To find:

Number of sides of a polygon

Solution:

Using sum of interior angles formula:

$S=(n-2) \times 180^{\circ}

where "S" is the sum of interior angels and "n" is the number of sides of a polygon.

Divide by 180° on both sides.

$\frac{S}{180^{\circ}}=\frac{(n-2) \times 180^{\circ}}{180^{\circ}}

Cancel common factor 180°.

$\frac{S}{180^{\circ}}=n-2

Add 2 on both sides.

$\frac{S}{180^{\circ}}+2=n-2+2

$\frac{S}{180^{\circ}}+2=n

Switch the sides.

$n=\frac{sum}{180^{\circ}}+2

Therefore number of sides of a polygon is n=\frac{sum}{180^{\circ}}+2.
