Answers

Answer 1

Answer:

D. 48

Step-by-step explanation:

QP = 16 (given)

LP = ?

Given that P is the centroid of the triangle, therefore:

QP = ⅓(QL) (based on the centroid theorem)

Plug in the value

16 = ⅓(QL)

Multiply both side by 3

3*16 = QL

48 = QL

QL = 48

Explain what the diameter of a circle is. If you had the diameter of a circle, how could you solve for the circumference?

Answers

Answer:

The diameter cannot solve for the circumference, you need the Radius to do it.

Step-by-step explanation:

If you want to use the Diameter divide the Diameter by 2. Diameter=D Radius=R

So to find the circumference of a Circle, 2÷D=R. Now we do 2[tex]\pi[/tex]R. So now to find the answer we have to do 2x[tex]\pi[/tex]xR

Which expressions correctly represent the area of the triangle XYZ?

Answers

Answer:

Options (2) and Option (1)

Step-by-step explanation:

Area of the ΔXYZ = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                              = [tex]\frac{1}{2}(XZ)h[/tex]

                              = [tex]\frac{1}{2}(18)h[/tex]

By applying sine rule in the ΔYPZ,

sin(38°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(38°) = [tex]\frac{h}{14}[/tex]

h = 14[sin(38°)]

Therefore, area of the given triangle = [tex]\frac{1}{2}(18)(14)sin(38)[/tex]

By applying sine rule in ΔYPZ,

sin(58°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(58°) = [tex]\frac{h}{10}[/tex]

h = 10sin(58°)

Area of ΔXYZ = [tex]\frac{1}{2}(18)(10)sin(58)[/tex]

Therefore, Options (2) and Option (1) are the correct options.

Step-by-step explanation:

Since these directions form a 90-degree angle, we can use the Pythagorean Theorem.

14^2 + 10^2 = c^2

196 + 100 = c^2

296 = c^2

It doesn't have a perfect square root, you can either say that it is [tex]\sqrt{296}[/tex] or approximately 17.205 miles.

Answers

Answer:

  no solution

Step-by-step explanation:

The equations describe parallel lines. There are no values of x and y that will satisfy both equations.

In standard form, the two equations are ...

  3x +7y = 21

  3x +7y = -42 . . . . . with positive leading coefficient

If (x, y) values satisfy the first equation, they cannot satisfy the second equation, and vice versa.

What is Addition?

Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.

When Houa was born her parents started a college fund for her. They initially put $3500 in the account. They saved an additional $550 per year.

Therefore, the balance of the account after 10 years is,

Balance after 10 years = $3500 + $550(Number of years)

                                      = $3500 + $550(10)

                                      = $9,000

Hence, the balance that the account will have after 10 years is $9,000.

On a standardized test, the mean is 37 and the standard deviation is 2.5. Approximately what percent of the scores fall in the range 32 - 42 ?

A) 68%
B) 95%
C) 34%
D) 99%

Answers

Answer:

B) 95%

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 37, standard deviation = 2.5

Approximately what percent of the scores fall in the range 32 - 42 ?

32 = 37 - 2*2.5

So 2 standard deviations below the mean

42 = 37 + 2*2.5

So 2 standard deviations above the mean.

This question is the percentage of scores within 2 standard deviations of the mean, so, by the Empirical Rule, it is 95%, option B.
