Cerrena [4.2K]

The equation says
A=p(1+r)^t
A=103(1+0.02)^t
So the interest rate is

KengaRu [80]

Answer:

19.8 years old

Step-by-step explanation:

If Z=(x-μ)/σ where Z=-1.32, σ=3.2, and μ=24, then:

-1.32=(x-24)/3.2

-4.224=x-24

19.776=x

19.8

Therefore, the age of a concert attendee with a z-score of -1.32 is 19.8 years old.

The amount of time it takes Victoria to solve crossword puzzles can be modeled by a continuous and uniformly distributed random

givi [52]

Answer:

80% probability that it will take Victoria greater than 8 minutes (total) for a puzzle that she has already been working on for 7 minutes

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X greater than x is given by the following formula.

$P(X > x) = 1 - \frac{x - a}{b-a}$

Uniformly distributed random time between 4 minutes and 12 minutes.

This means that $a = 4, b = 12$

What is the probability that it will take Victoria greater than 8 minutes (total) for a puzzle that she has already been working on for 7 minutes?

Already working for 7 minutes, so a is updated to 7.

$P(X > 8) = 1 - \frac{8 - 7}{12 - 7} = 0.8$

80% probability that it will take Victoria greater than 8 minutes (total) for a puzzle that she has already been working on for 7 minutes

Where is the vertex of the parabola?

True [87]

$\bf \textit{vertex of a vertical parabola, using coefficients}
\\\\
\begin{array}{llcccl}
y = & 1x^2& +6x& +7\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}
\qquad 
\left(-\cfrac{ b}{2 a}\quad ,\quad c-\cfrac{ b^2}{4 a}\right)
\\\\\\
\left( -\cfrac{6}{2(1)}~~,~~7-\cfrac{6^2}{4(1)} \right)\implies (-3~~,~~7-9)\implies (-3~~,~~-2)$
