Next number in the sequence 1 4 9 16 25
Anarel [89]

The next number in the sequence is 36.

Starting from 1, the number increases by 3, 1 + 3 = 4. But the next number, the number it's being increased by increases by 2. 3 + 2 = 5, 4 + 5 = 9. And again, 5 + 2 = 7, 7 + 9 = 16. And again. 7 + 2 = 9, 16 + 9 = 25. Therefore, it is increased to + 11, and the next number is 36.

I hope this helped, and you have a great day!

g Disco Fever is randomly found in one half of one percent of the general population. Testing a swatch of clothing for the prese
Marizza181 [45]

Answer:

The probability that the result is positive is P=0.04475=4.475%.

Step-by-step explanation:

We have the events:

D: disease present

ND: disease not present

P: test positive

F: test false

Then, the information we have is:

P(D)=0.005

P(P | D)=0.99

P(P | ND)=0.04

The total amount of positive test are the sum of the positive when the disease is present and the false positives (positive tests when the disease is not present).

P(P)=P(P | D)*P(D)+P(P | ND)*(1-P(D))\\\\P(P)=0.99*0.005+0.04*0.995\\\\P(P)=0.00495+0.0398=0.04475

The probability that the result is positive is P=0.04475.

Help, I don’t know what I’m doing<br> Trigonometry
spin [16.1K]

Answer:

\frac{\sqrt{3} }{6}

Step-by-step explanation:

using the 30- 60- 90 triangle for exact values , then

tan60° = \sqrt{3} , and

cot60° = \frac{1}{tan60} = \frac{1}{\sqrt{3} }

cos60° = \frac{1}{2}

cot60° cos60°

= \frac{1}{\sqrt{3} } × \frac{1}{2}

= \frac{1}{2\sqrt{3} } ← rationalise the denominator by multiplying by \frac{\sqrt{3} }{\sqrt{3} }

= \frac{1}{2\sqrt{3} } × \frac{\sqrt{3} }{\sqrt{3} }

= \frac{\sqrt{3} }{6}
