\texttt{\:Coordinates of vertex = (5,2)}

\texttt{The graph has a maximum}

\tt  \: Axis\:\: of \:\; symmetry : x = 5\

____________________________________

\large \tt Solution  \: :

Coordinate of vertex is the point where there's a unique (only one) value of y for x :

\qquad \tt \rightarrow \: (5,2)

Since it's a downward parabola, it doesn't have defined minima, as it's value reach [ - infinity ]

and hence, it has a maximum, at the vertex.

Axis of symmetry is the line that divides the parabola into two equal regions that are mirror images of each other.

it is the line passing through vertex and parallel to y - axis.

\qquad \tt \rightarrow \: x = 5

cara works at a fine jewelry store and earns a commission on her total sales for the week. her weekly paycheck was in the amount
Gekata [30.6K]

Cara's rate of commission is 12%.

Step-by-step explanation:

Given,

Paycheck = $6500

Salary = $1000

Commission = Paycheck - Salary

Commission = 6500-1000 = $5500

Total sales for the week = $45000

Commission rate = \frac{Commission}{Total\ Sales}*100

Commission\ rate=\frac{5500}{45000}*100\\\\Commission\ rate=\frac{550000}{45000}\\\\ Commission\ rate=12.22\%

Rounding off to nearest whole number.

Commission rate = 12%

Cara's rate of commission is 12%.

In what follows use any of the following tests: Regression, multiple regression, one-sided t-test, or two-sided t-test. All conc
Yakvenalex [24]

Answer:

  1. Two sided  t-test ( d )
  2.  0.245782  ( c )
  3. Since P-value is too large we cannot conclude that the students’ weight are different for these two schools. ( c )
  4. The test is inconclusive; thus we cannot claim that the average weights are different. ( b )

Step-by-step explanation:

1)  Test performed is a Two sided test and this because we are trying to determine the mean difference between two groups irrespective of their direction

<u>2) Determine the P-value ( we will use a data-data analysis approach on excel data sheet while assuming Unequal variances )</u>

                               yes             No

Mean                   94.47059   89.76471

Variance              173.2647     95.19118

Observations            17            17

df                               30

t Stat                       1.184211  

P(T<=t) one-tail 0.122814  

t Critical one-tail 1.697261

P(T<=t) two-tail        0.245782

Hence The p-value =  0.245782

3) Since P-value is too large we cannot conclude that the students’ weight are different for these two schools.

4)   The test is inconclusive; thus we cannot claim that the average weights are different.
