Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37 points.

Step-by-step explanation:

Let Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37 denote a normal random variable with mean Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37 and standard deviation Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37. (That is: Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37.) By definition, the Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37-score of an observation with value Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37 would be:

Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37.

In this question, the value of Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37 is given. Also given are the value of the observation Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37 and the corresponding Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37-score, Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37. Rearrange the Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37-score definition Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37 to find an expression for Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37:

Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37.

Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37.

Floretta s points per basketball game are normally, №18010035, 15.05.2022 08:37.

26 points.

Step-by-step explanation:

Let X denote a normal random variable with mean \mu and standard deviation \sigma. (That is: X \sim {\rm N}(\mu,\, \sigma).) By definition, the z-score of an observation with value X = x would be:

\begin{aligned} z&= \frac{x - \mu}{\sigma}\end{aligned}.

In this question, the value of \sigma is given. Also given are the value of the observation x and the corresponding z-score, z\!. Rearrange the \! z-score definition z = (x - \mu) / \sigma to find an expression for \mu:

\begin{aligned} x - \mu = \sigma\, z\end{aligned}.

-\mu = (-x) + \sigma\, z.

\begin{aligned}\mu = x - \sigma\, z\end{aligned}.

Substitute in the value of x, \sigma, and z to find the value of \mu, the mean of this normal random variable:

\begin{aligned}\mu &= x - \sigma\, z \\ &= 10 - (-16) \\ &= 26\end{aligned}.

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

Cost before sale tax=$46.00

Cost after including tax=$48.76

Sale tax=$48.76-46.00

=$2.76

we know,

sale tax=((sales tax rate)/100) * cost before sale tax

2.76=((sales tax rate)/100) *46.00

sale tax rate=(2.76*100)/46

                   =276/46

                    =6%

There fore sales tax rate=6%
