Many states assess skills of their students in various grades. One program that is available for this purpose is the NAEP. One of the tests provided by the NAEP assesses the reading skills of 12th grade students. In a recent year, the national mean score was 288 and the standard deviation was 38. Assuming the scores are approximately normal, give a range of scores that includes 99.7% of these students.

Required:
How high a score is needed to be in the top 25% of students who take this exam (use technology)?

Answers

Solution :

Given :

National mean score of the reading test that is conducted the NAEP = 288

Standard deviation of the score = 38

Therefore, P(X > x) = 0.25

P (Z > [tex]$\frac{x-288}{38} $[/tex] = 0.674)

[tex]$\frac{x-288}{38} = 0.674$[/tex]

[tex]$x=288+(38 \times 0.674)$[/tex]

x = 326.67

Therefore, the highest score that is needed for the students to be in the top of 25 percent among the students those who take the exam.

suppose that the population of deer in a state is 16,000 and is growing 1%each year Predict population after 6 years

Answers

Answer:

16984

Step-by-step explanation:

Given

[tex]a = 16000[/tex] ---- Initial

[tex]r = 1\%[/tex] --- rate

Required

Determine the population after 6 years

To do this, we make use of the following exponential function

[tex]f(x) = a(r+1)^x[/tex]

Substitute values for a and r

[tex]f(x) = 16000(1\%+1)^x[/tex]

Express 1% and decimal

[tex]f(x) = 16000(0.01+1)^x[/tex]

[tex]f(x) = 16000(1.01)^x[/tex]

The population after 6 years is:

Substitute 6 for years

[tex]f(6) = 16000(1.01)^6[/tex]

[tex]f(6) = 16984.3224096[/tex]

[tex]f(6) = 16984[/tex] -- approximated

The third leg of the right-angle triangle will be 12 cm.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

The hypotenuse of the right-angle triangle is 13 cm and the perpendicular of the right-angle triangle is 5 cm.

Then the measure of the third side (B) of the right-angle triangle will be

13² = 5² + B²

169 = 25 + B²

 B² = 169 - 25

 B² = 144

   B = 12

Thus, the third leg of the right-angle triangle will be 12 cm.

Sin 40/8 = sin(x) / 7             Multiply both sides by 7

7* Sin(40) / 8 = sin(x)

Sin(40) = 0.6428

7 * 0.6428 / 8 = sin(x)

.56245 = sin(x)

x = sin-1(0.56245)

x = 34.23

Darby bought a rare baseball card for $2,000. Three years later, the value of the card had increased 35% of its original value. By how much did the value of Darby’s baseball card increase?

$___

Answers

Answer: 700 dollars

================================================

Work Shown:

35% = 35/100 = 0.35

35% of 2000 = 0.35*2000 = 700

Since the card increased by 700 dollars, this means the card is now worth 2000+700 = 2700 dollars.

Marc sold 425 tickets for the school play. Student tickets cost $4 and adult tickets cost $5. Marc's sales totaled $1925. How many adult tickets and how many student tickets did Marc sell?

Answers

Answer: a=225 adult, s=200 student

Explanation: We need a system of equations to find how many of each ticket Marc sold and we can use 4s+5a=1925 and s+a=425.

If we isolate a, we will have a=425-s

If we plug this into the first equation, we will get 4s+2125-5s=1925

Solving for s gives us s=200.

To find a, we can do 425-200 to find that a=225.
