Answer:

t = –3.382

Step-by-step explanation:

Claim: FICO credit scores are greater than 675

Thus, x = 675

We are given:

Sample size = n = 50

Sample Mean = u = 719

Sample Standard deviation = s = 92

The formula to find the t-statistic is:

[tex]t=\frac{x-u}{\frac{s}{\sqrt{n} } }[/tex]

Using the above values, we get:

[tex]t=\frac{675-719}{\frac{92}{\sqrt{50} } }\\\\ t=-3.382[/tex]

Thus, the value of test statistic is -3.382. So 3rd option gives the correct answer.

[tex]y=4x+18[/tex]

Step-by-step explanation:

Let

x----> the time in hours

y----> the total inches of snow on the ground

we know that

The function that best model this situation is the linear function

so

[tex]y=mx+b[/tex]

In this problem

[tex]m=4\frac{in}{h}[/tex]

[tex]b=18\ in[/tex] ----> the y-intercept

substitute

[tex]y=4x+18[/tex]

Question:

A ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour. Which type of functions best models this situation?

A) exponential

B) linear

C) quadratic

D) radical

Answer & Step-by-step explanation:

It is given that a ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour.

If a function has constant rate of change, then the it is a linear function.

It the given case the rate of change is constant so linear function best model this situation.

The slope intercept form of linear function is

f(x)=mx+b           ... (1)

where, m is slope and b is y-intercept or initial value.

Ski resort has 18 inches of snow on the ground it means initial value is 18.

The snow is falling at a rate of 4 inches per hour. So, m=4.

Substitute m=4 and b=18 in equation (1).

f(x)=4x+18

Therefore Linear decreasing function best model this situation and the required function is f(x)=4x+18.

Hope this helps.

Answer:

Option C will have greatest number of permutations.

Step-by-step explanation:

A.

The number of license plates with 4 letters followed by 3 numbers, where letters and digits cannot be repeated.

We have total 26 letters (A_Z) and the letters can't be repeated. So we have 26 letter options for 1st letter

25 letters options for 2nd letter

24 letter options for 3rd letter

23 letter options for 4th letter.

So total options for 4 letters 26*25*24*23 = 358800

Now, 3 numbers are required. We have total 10 numbers (0-9)

10 number options for 1st number

9 number options for 2nd number

8 number options for 3rd number

Total options for 3 numbers= 10*9*8 = 720

total options for 4 letters and 3 numbers will be: 358800 * 720 = 258,336,000

B.

The number of license plates with 3 letters followed by 4 numbers, where letters and digits cannot be repeated.

We have total 26 letters (A_Z) and the letters can't be repeated. So we have 26 letter options for 1st letter

25 letters options for 2nd letter

24 letter options for 3rd letter

So total options for 3 letters= 26*25*24 = 15600

Now, 4 numbers are required. We have total 10 numbers (0-9)

10 number options for 1st number

9 number options for 2nd number

8 number options for 3rd number

7 number options for 4th number

Total options for 4 numbers = 10*9*8*7 = 5040

total options for 4 letters and 3 numbers will be: 15600 * 5040 = 78,624,000

C. The number of license plates with 4 letters followed by 3 numbers, where letters and digits can be repeated.

Now, the letters and digits can be repeated. So we have 26 options for each 4 letters and 10 options for each 3 numbers

26*26*26*26 *10*10*10 = 456,976 * 10,00 = 456,976,000

total options for 4 letters and 3 numbers will be: 456,976,000

D.

The number of license plates with 3 letters followed by 4 numbers, where letters and digits can be repeated.

Now, the letters and digits can be repeated. So we have 26 options for each 3 letters and 10 options for each 4 numbers

26*26*26 *10*10*10*10 = 17,576 * 10,000 = 175,760,000

total options for 3 letters and 4 numbers will be: 175,760,000

So, Option C will have greatest number of permutations.

Answer: 4.47 seconds.

Step-by-step explanation:

Hi, the rock will reach the river when the height (h) is 0.

So, replacing in the equation given:

h= -16t2+320

Where t is the time  

0= -16t2+320

Solving for t

-320 = -16t2

-320/-16 =t2

20 = t2

√20 =t

4.47 = t

Assuming that t is the time in seconds, the rock will reach the river after 4.47 seconds.

Answer:

The total interest paid by Nell in 20 years is $3,724.80

C is correct

Step-by-step explanation:

Nell took out a subsidized student loan of $6000 at a 4.8% APR, compounded  monthly.

First we find total amount in 10 months

[tex]A=6000(1+\frac{0.048}{12})^{10}[/tex]

[tex]A=6244.37[/tex]

Now, He has to pay loan off on 6244.37 for 20 years at 4.8% APR

Loan Formula:

[tex]P=\dfrac{PV\cdot r}{1-(1+r)^{-n}}[/tex]

PV=6244.37

r=0.048/12

n=240

[tex]P=\dfrac{6244.37\times \frac{0.048}{12}}{1-(1+\frac{0.048}{12})^{-240}}[/tex]

[tex]P=40.52[/tex]

Total pay in 20 years = 40.52 x 20 = 9724.80

Total amount took loan = $6000

Interest = 9724.80 - 6000

             = $3,724.80

Hence, The total interest paid by Nell in 20 years is $3,724.80

Answer: Obtion B

[tex]P = 1.3e ^ {-0.038t}\\\\P = 2.1e ^ {-0.046t}[/tex]

Step-by-step explanation:

The equation for exponential decay has the following form:

[tex]y = pe ^{-rt}[/tex]

Where

p is the initial population  

r is the rate of decrease

t is time.

In this problem we have to:

The current population of insect A to be 1.3 million and the current population of insect B to be 2.1 million.

So

[tex]p_1 = 1.3[/tex]  in millions

[tex]p_2 = 2.1[/tex]  in millions

We also need the populations of insect to be reduced at a rate of 3.8% and insect to be reduced at a rate of 4.6%.

so:

[tex]r_1 = 0.038\\\\r_2 = 0.046[/tex]

then the exponential decay equation for insect A is:

[tex]P = 1.3e ^ {-0.038t}[/tex]

the exponential decay equation for insect B is:

[tex]P = 2.1e ^ {-0.046t}[/tex]

Finally, the system of equations is:

[tex]P = 1.3e ^ {-0.038t}\\\\P = 2.1e ^ {-0.046t}[/tex]

The answer is the Option B

Answer:

5.4 ft²

Step-by-step explanation:

Since the circle is inscribed in the square then radius r = 2.5

Area of yellow = area of square - area of circle

A = (5 × 5) - (π × 2.5²)

  = 25 - 6.25π ≈ 5.4 ft²

Answer:

Area of the Yellow Region is 5.4 ft²

Step-by-step explanation:

Given:

Length of the side of the square = 5 ft

Diameter of the Circle = Length of the side = 5 ft

⇒ Radius of the circle, r = 5/2 = 2.5 ft

To find: Area of the Yellow region from the figure.

Area of the Yellow Region = Area of the Square - Area of the Circle

                                            = Side × Side - πr²

                                            = 5 × 5 - 3.14 × (2.5)²

                                            = 25 - 3.14 × 6.25

                                            = 25 - 19.625

                                            = 5.375

                                            ≈ 5.4 ft²   (nearest tenth)

Therefore, Area of the Yellow Region is 5.4 ft²

Answer:

16

Step-by-step explanation:

h(x) × h(x) = (6 - x)²

(h × h)(10) = (6 - 10)² = (- 4)² = 16

For this case we have by definition, that given two functions, then:

[tex](f * g) (x) = f (x) + g (x)[/tex]

Here, we want to find ([tex](h * h) (x):[/tex]

[tex](h * h) (x) = (6-x) (6-x)\\(h * h) (x) = 36-6x-6x + x ^ 2\\(h * h) (x) = 36-12x + x ^ 2[/tex]

We want to find the value of the function when [tex]x = 10[/tex].

[tex](h * h) (10) = 36-12 (10) + (10) ^ 2\\(h * h) (10) = 36-120 + 100\\(h * h) (x) = 16[/tex]

Answer:

6600 / 165 = 40

Answer:

Final answer is $4440.

Step-by-step explanation:

Let amount of money invested in 8% stock = x

Let amount of money invested in 6% stock = y

then total money invested $325.6 gives equation

8% of x + 6% of y = 325.6

0.08x + 0.06y = 325.6

8x + 6y = 32560...(i)

other equation will be x=2y...(ii)

plug (ii) into (i)

8x + 6y = 32560

8(2y) + 6y = 32560

16y+ 6y = 32560

22y = 32560

[tex]y=\frac{32560}{22}[/tex]

y=1480

plug y=1480 into (ii)

x=2y=2(1480)=2960

Then total money invested in stocks = x+y= 1480+2960=4440

Hence final answer is $4440.

The domain of a function is the complete set of possible values of the independent variable.

The cosine function is represented by the expression: y=cos(x), where "x" is the independent function, and "y" the dependent function. So the domain comes to be all the values that "x" can take.

The domain of the cosine function is all the real numbers. All this can be verified by looking at its graph (attached)

Answer:

x²+y²-4y-46=0

Step-by-step explanation:

the equation of a circle is in the form (x - a)² + (y - b)² = r², where (a,b) is the center of the circle

the equation is (x - 0)² + (y - 2)² = r², where r is the radius. But r is the distance from (0,2) to (7,3)

the distance from two points is given by r² = (x₁ -x₂)² + (y₁ - y₂)²

r²= (0 - 7)² + (2 - 3)²

r² = 49 + 1 = 50

hence the equation is  

                  (x)² + (y - 2)² = 50

                  x²+y²-4y+4 = 50

                 x²+y²-4y-46= 0
