hello

to solve this question, we need to use know the number of possible outcomes

\begin{gathered} \text{probability = }\frac{nX}{nS} \\ S=\text{  number of possible outcomes} \\ X=\text{ number of events} \end{gathered}

let's find the number of possible outcomes

we have four tiles numbered 1, 4, 5 and 8

possible outcomes are

undefined

Does 25/60 and 8/20 form a proportion ?​
notka56 [123]

Answer:

No.

Step-by-step explanation:

Change it so that both fractions would have the same denominator. Note that what you do to the denominator, you must also do to the numerator.

Multiply 3 to both the numerator & denominator of 8/20

(8/20)(3/3) = 24/60

24/60 ≠ 25/60 ∴ these 2 fractions are not proportional.

FInd the GCF of the numbers using prime factorizations.
lesya [120]

Answer:

GCF(330, 75, 450, 225) = 15

Steps:

Prime factorization of the numbers:

330 = 2 × 3 × 5 × 11

75 = 3 × 5 × 5

450 = 2 × 3 × 3 × 5 × 5

225 = 3 × 3 × 5 × 5

GCF(330, 75, 450, 225)

= 3 × 5

= 15

Planes S and R both intersect plane T .
neonofarm [45]
<h2>[A] Plane S contains points B and E.</h2>

False

As indicated in Figure A below, Plane S contains only point B (remarked in red). Point E (remarked in blue) lies on plane R.

<h2>[B] The line containing points A and B lies entirely in plane T.</h2>

True

As indicated in Figure B below, the line containing points A and B lies entirely in plane T. That line has been remarked in red and it is obvious that lies on plane T.

<h2>[C] Line v intersects lines x and y at the same point.</h2>

False

As indicated in Figure C below, line v intersects lines x and y, but line x in intersected at point B while line y (remarked in red) is intersected at point A (remarked in blue), and they are two different points, not the same.

<h2>[D] Line z intersects plane S at point C.</h2>

True

As indicated in Figure D below, line z that has been remarked in yellow, intersects plane S at point C that has been remarked in blue.

<h2>[E]  Planes R and T intersect at line y.</h2>

True

As indicated in Figure E below, planes R and T intersect at line y. The line of intersection has been remarked in red.
