<u>Answer:</u>

The given statement is False statement

<u>Explanation:</u>

We are given that Jaime has blown out a number of candles equal to his age on each of his birthday till now and he is 9 years old now so the total number of candles blown by him all his life is given by the

arithmetic series

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 and

not the arithmetic series

0 + 1 + 2 + 3+ 4+ 5+ 6+ 7+ 9 as given

so the given statement is false.

A game is played with a spinner on a circle, like the minute hand on a clock. The circle is marked evenly from 0 to 100, so, for
zheka24 [161]

Answer:

The probability is 1/2

Step-by-step explanation:

The time a person is given corresponds to a uniform distribution with values between 0 and 100. The mean of this distribution is 0+100/2 = 50 and the variance is (100-0)²/12 = 833.3.

When we take 100 players we are taking 100 independent samples from this same random variable. The mean sample, lets call it X, has equal mean but the variance is equal to the variance divided by the length of the sample, hence it is 833.3/100 = 8.333.

As a consecuence of the Central Limit Theorem, the mean sample (taken from independant identically distributed random variables) has distribution Normal with parameters μ = 50, σ= 8.333. We take the standarization of X, calling it W, whose distribution is Normal Standard, in other words

W = \frac{X - \mu}{\sigma} = \frac{X - 50}{8.333} \simeq N(0,1)

The values of the cummulative distribution of the Standard Normal distribution, lets denote it \phi , are tabulated and they can be found in the attached file, We want to know when X is above 50, we can solve that by using the standarization

P(X > 50) = P(\frac{X-50}{8.33} > \frac{50-50}{8.33}) = P(W > 0) = \phi(0) = 1/2

What is the 4th term in a geometric sequence for which a1=15 and r=1/3
Hitman42 [59]
Geometric goes liket his
a_n=a_1(r)^{n-1}
given
a1=15
r=1/3
find a4 or 4th term

a_4=15( \frac{1}{3} )^{4-1}
a_4=15( \frac{1}{3} )^{3}
a_4=15 (\frac{1}{27})
a_4=\frac{15}{27}
a_4=\frac{5}{9}
4th term is 5/9

Find the x-coordinates of the two points on the curve
scZoUnD [109]

Answer: x = {-2, 2}

<u>Step-by-step explanation:</u>

Tangent means it is touching. Find the intersection of the two equations.

Solve the linear equation for y, then set the two equations equal to each other.

4y=x+8\qquad \rightarrow \qquad y=\dfrac{x+8}{4}

\dfrac{x-1}{x}=\dfrac{x+8}{4}\\\\\\\text{Cross multiply and solve for x:}\\4(x-1)=x(x+8)\\4x-4=x^2+8x\\.\qquad 0=x^2+4x+4\\.\qquad 0=(x+2)^2\\.\qquad 0=x+2\\.\qquad x=-2

To find the next point that is parallel to the linear equation and tangent to the curve, we need to use the linear equation with slope (m) = \dfrac{1}{4} and unknown b.

Let's try b = 0, then the equation of the linear equation is: y=\dfrac{1}{4}x

Set the equations equal to each other and solve for x:

\dfrac{x-1}{x}=\dfrac{x}{4}\\\\\\4(x-1)=x^2\\4x-4=x^2\\.\qquad 0=x^2-4x+4\\.\qquad 0=(x-2)^2\\.\qquad 0=x-2\\.\qquad x=2

This works!!!  If it didn't work, we would have tried other values for b until we arrived at a solution.
