suppose that 12 different people call you in a week. what is the probability you will get at least one phone call per day (assum

e 7 days in the week)? use a mc simulation to estimate this probability with a margin of error of 0.005.

Find the 57th term of the sequence 74n-29, where n represents the position of a term in sequence.

zhannawk [14.2K]

Answer:

4189

Step-by-step explanation:

Given sequence is:

$a_n=74n-29$

Plugging n = 57 in the given sequence, we find:

$a_{57}=74(57)-29$

$a_{57}=4218-29$

$\huge \red{a_{57}= \boxed{4189}}$

A triangle has three sides: a, b, and c. Side a = 72 feet, and side b = 154 feet, and side c = 170 feet. True or false: this tri

Juliette [100K]

Answer:

True

Step-by-step explanation:

If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²

c is the largest side and a and b are the two smaller sides of the triangle.

So if this is true then √72² + 154² should be 170:

170² = 72² + 154²

28900 = 5184 + 23716

28900 = 28900

So we have proved using Pythagoras theorem that the triangle is a right angled triangle.

Find the first four terms of the recursive sequence defined by the following formula:

NISA [10]

Answer:

144, 36, 9, 2 $\frac{1}{4}$

Step-by-step explanation:

The recursive formula allows us to find a term in a sequence from the previous term.

Given

$a_{n}$ = $\frac{a_{n-1} }{4}$

Given the fourth term we require to work back to the third term , second and so on. Rearrange the formula to give

Multiply both sides by 4, then

$a_{n-1}$ = 4 $a_{n}$

Given a₄ = 2 $\frac{1}{4}$ , then

a₃ = 4 × a₄ = 4 × 2 $\frac{1}{4}$ = 9

a₂ = 4 × a₃ = 4 × 9 = 36

a₁ = 4 × a₂ = 4 × 36 = 144
