It's like this: all chocolate cake is cake, but not all cake is chocolate cake. A square is a type of rectangle, but only squares can be squares, not all rectangles can be squares. Does that make sense?

Answer:

The answer to your question is the letter D) 46°

Step-by-step explanation:

Data

length = 25 ft

Opposite side = 18 ft

Angle = Ф

To solve this problem, use trigonometric functions. The trigonometric function that relates the Opposite side and the hypotenuse is sine.

Sin Ф = Opposite side / hypotenuse

-Substitution

sin Ф = 18/25

-Simplification

sin Ф = 0.72

-Result

sin⁻¹ Ф = 0.72 = 46°

sashaice [31]

Answer:

1.1

Step-by-step explanation:

Find the mean of the data:(3+4+5+5+5+6+6+6+7+8)/10 = 5.5Step 2: Find the difference between each data and mean:Difference between 3 and 5.5 is 2.5Difference between 4 and 5.5 is 1.5Difference between 5 and 5.5 is 0.5Difference between 5 and 5.5 is 0.5Difference between 5 and 5.5 is 0.5Difference between 6 and 5.5 is 0.5Difference between 6 and 5.5 is 0.5Difference between 6 and 5.5 is 0.5Difference between 7 and 5.5 is 1.5Difference between 8 and 5.5 is 2.5Step 3: Add all the differences:2.5+1.5+0.5+0.5+0.5+0.5+0.5+0.5+1.5+2.5 = 11Step 4: Divide it by the number of data:11/10 = 1.1So, the MAD = 1.1

There are 19 figure skaters in the Olympic women's competition, including 3 Americans. The gold medal goes to first place, silve
muminat

There are three different choices for the American.

There are 16 different choices for the first non-American and 15 different choices for the other non-American.

So, there are 3 x 16 x 15 different groups.

But, order is important -- who gets the gold, who gets the silver, and who gets the bronze -- there are 6 different ways to arrange the 3 winners (3! = 6).

Thus, there are 6 x 3 x 16 x 15 different results.

If y varies jointly as x and z and y = 12 when x = -2 and z=3, find y when x is 4 and z is -1
jeka57 [31]

Answer:

D. 8​

Step-by-step explanation:

y varies jointly as x and z

y = k(xz)

-------------------------

Find k, the constant of variation

y = 12 when x = -2 and z=3

12 = k(-2 * 3)

12 = k(-6)

k = -2

-------------------------

find y when x is 4 and z is -1

using k = -2

y = -2(4 * -1)

y = -2(-4)

y = 8
