On the Sat the lowest value anyone can score on the math section is 200 and the highest is 800. Jason is a senior retaking the S

AT in March to score higher on the SAT math section. He has been practicing to improve his score from this original test. He is currently taking a practice test with 58 math questions that mocks the SAT, Let X= the number he gets correct on the practice test with a mean of 38 questions and a standard deviation of 4.8 questions. Let Y= Jason’s predicted score on the SAT from a randomly selected practice test modeled by the equation Y=10.34X+200.

Answer:

10 people

Step-by-step explanation:

Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.

The amount spent on just tickets is therefore:

= 243.25 - 15.75

= $227.50.

If $227.50 was for tickets alone, the number of tickets they could buy is:

= Total amount left/ Price of tickets

= 227.50 / 22.75

= 10 people

A picture shows the net of the lateral surface of the cone. Which statement about this cone is NOT true?
Brut [27]

Answer:

Area of the Net is incorrect

Step-by-step explanation:

Base Surface Area =  π×12^2

=  452.38934211693 inches^2

Lateral Surface Area =  π×12×√12^2 + 15^2

=  724.1762903163 inches^2

Total Surface Area = 1176.5656324332 inches^2

Frequency (y) varies inversely with wavelength (x). Find the frequency (measured in THz ) of blue light if its k value is 175,72
horsena [70]

We have been that frequency (y) varies inversely with wavelength (x).

We know that two inversely proportional quantities are in form a=\frac{k}{b}, where a is inversely proportional to b and k is constant of variation.

Our required equation would be y=\frac{k}{x}.

To find frequency of blue light, we will substitute k=175,720 and x=230 in our equation as:

y=\frac{175,720}{230}

y=764

Therefore, the frequency of blue light is 764.

A student determined that the area of the segment of c shown above is Asegment = 137.71 ft2. The student's work is shown below.
ivolga24 [154]

Answer:

Option D. The student did not use the correct formula to calculate the area of the segment

Step-by-step explanation:

step 1

Find the area of the isosceles triangle

Applying the law of sines

A=\frac{1}{2}(12^{2})sin(60\°)=62.35\ ft^{2}

step 2

Find the area of the sector

The area of the sector is 1/6 of the area of the circle

so

A=\pi r^{2}/6

substitute the value

A=(3.14)(12)^{2}/6=75.36\ ft^{2}

step 3

Find the area of the segment

The area of the segment is equal to the area of sector minus the area of triangle

A=75.36\ ft^{2}-62.35\ ft^{2}=13.01\ ft^{2}

therefore

The student did not use the correct formula to calculate the area of the segment
