Answer:

P(marks ≥ 20) = 0.4

Step-by-step explanation:

Marks gotten by the 5 students are;

15, 14, 20, 17, 25

Marks more than or equal to 20 are 2 in number namely 20 and 25.

Thus, probability of getting marks more than or equal to 20 is;

P(marks ≥ 20) = 2/5

P(marks ≥ 20) = 0.4

Find the missing number:
nirvana33 [79]

Answer:

20%

Step-by-step explanation:

Not sure if this is exactly correct, but let's say we start with 1 unit. If it increased by 25%, we get:

1 × 1.25 = 1.25 units.

Now, to get back to 1 unit, we need to find:

1.25 × ?  = 1

? = \frac{1}{1.25} = 0.80

So, 100% - 80 % = 20%

A 20% decrease.

Not completely sure though.

Fifteen is no more than a number t divided by 5,What is the inequality?
Allisa [31]

An inequality may be used to model the given situation. The phrase, "no more than" implies "less than or equal to". Therefore, the inequality is:

15 ≤ t / 5

Solving the inequality of t, we get:

t ≥ 75

This means that the number t is at least 75 (the phrase at least implies greater than or equal to)

Hope this helps!

4(2i-3)=20 can someone solve this for me​
natka813 [3]

Hi!

I can help you with joy!

First, use the Distributive Property:

4(2i-3)=20

8i-12=20

Now, move -12 to both sides, using the opposite operation:

8i=20+12

8i=32

Now, divide both sides by 8:

i = 4 (Answer)

Hope it helps.
