8 0

Answer:

21 / 400

Step-by-step explanation:

Given 8 cherry, 5 grape, and 7 orange gummy vitamins out of the multivitamin container.

The probability that Julio will select an orange multivitamin is

7 ÷ 8 + 5 + 7 = 7/20

Also, given 11 berry, 3 lemon, and 6 pineapple gummy vitamins out of the calcium container

The probability that Julio will select a lemon calcium is

3 ÷ 11 + 3 + 6 = 3/20

Therefore, since the event of selecting are independent of each other

probability that Julio will select an orange multivitamin and a lemon calcium vitamin is

7/20 × 3/20

= 21 / 400

Its not telling me how to do this, please help

kenny6666 [7]

Step-by-step explanation:

Actually, it tells you exactly what to do.

First, translate, i.e., move over, the coordinates up by 3:

$(1, 4)\rightarrow (1+3, 4+3) = (4, 7)$

Then reflect this point about the x-axis and to do this,

$(x, y) \rightarrow (x, -y)$

$(4, 7) \rightarrow (4, -7)$

A 6-foot man walks on level ground toward a 60 foot flag pole. He notes different angles of elevation θ to the top of the pole w

krek1111 [17]

Answer:

a) x = 54/tan(theta)

b) theta = arctan(54/x)

Step-by-step explanation:

a) The tangent ratio is the ratio of the side opposite an acute angle in a right triangle to the adjacent side. For the angle of elevation, the adjacent side is the distance x to the flagpole. The side opposite is the 54-foot difference between the top of the man's head and the top of the flagpole. So, we have ...

tan(theta) = 54/x

Solving for x gives ...

x = 54/tan(theta)

b) Solving the first equation in the previous part for theta involves the inverse tangent function:

theta = arctan(54/x)
