The SAT Reasoning Test is perhaps the most widely used standardized test for college admissions in the United States. Scores are

based on a normal distribution with a mean of 1,500 and a standard deviation of 300. Clinton College would like to offer an honors scholarship to students who score in the top 10% of this test. What is the minimum score that qualifies for the scholarship?

Answer:

  1885

Step-by-step explanation:

A score of 1884 is just below the top 10%. To be in the top 10%, the score must be 1885 or higher.

A suitable calculator or spreadsheet is about the easiest way to figure this.

slamgirl [31]

Answer:

New = -92\frac{1}{8}

Step-by-step explanation:

Given:

x = -75\frac{3}{4} --- Position

\triangle x = -16\frac{3}{8} --- Change

Required

Find the new position

The new position is calculated as:

New = x + \triangle x

New = -75\frac{3}{4} - 16\frac{3}{8}

New = -75.75 - 16.375

New = -92.125

New = -92\frac{125}{1000}

New = -92\frac{1}{8}

The equation for the cost in dollars of producing automobile tires is c = 0.000015x2 - 0.03x + 35, where x is the number of tire
statuscvo [17]
The cost function is
c = 0.000015x² - 0.03x + 35
where x = number of tires.

To find the value of x that minimizes cost, the derivative of c with respect to x should be zero. Therefore
0.000015*2x - 0.03 = 0
0.00003x = 0.03
x = 1000

Note:
The second derivative of c with respect to x is positive (= 0.00003), so the value for x will yield the minimum value.

The minimum cost is
Cmin = 0.000015*1000² - 0.03*1000 + 35
          = 20

Answer:
Number of tires = 1000
Minimum cost = 20

What is the surface area of this design? 5 in 5 in 6.4 in 5 in 9 in
xeze [42]

ANSWER

197 {in}^{2}

EXPLANATION

The area of the two tra-pezoidal faces

= 2 \times  \frac{1}{2}  \times (9 + 5) \times 5 = 70 {in}^{2}

The area of the 5 by 6.4 rectangular face

= 6.4 \times 5 = 32  {in}^{2}

The area of the two square faces

= 2(5 \times 5) = 50 {in}^{2}

The area of the 9 by 5 rectangular face is

= 9 \times 5 = 45 {in}^{2}

The surface area of the design is:

70 + 32 + 50  + 45=197 {in}^{2}
