You spin the spinner and flip a coin. Find the probability of the compound event.
Nitella [24]

Answer:

1/10

Step-by-step explanation:

The probability of flipping heads is 1 out of 2 or 1/2

The probability of getting a 5 on the spinner is 1/5

The probability of getting both is 1/2  *  1/5 = 1/10

You should try this out by listing all the ways this can happen.

Spinner         Coin

1                     H

2                    H

3                    H

4                    H

<em><u>5                    H</u></em>

1                     T

2                    T

3                    T

4                    T

5                    T

There are 10 ways of this problem giving results. Only 1 of them is correct.

In right triangle DEF, ∠E is a right angle, m∠D=26∘, and DF=4.5.
jok3333 [9.3K]

Answer:

The measurement of EF is 1.98 units

Step-by-step explanation:

In Δ DEF

∵ m∠E = 90°

∴ FD is the hypotenuse of the triangle

∵ m∠D = 26°

∵ EF is opposite to angle D

- We can use the sine ratio to find it

∵ sin D = \frac{EF}{FD} ⇒ (opposite side / hypotenuse)

∵ FD = 4.5 units

∴ sin(26) = \frac{EF}{4.5}

- Multiply both sides by 4.5

∴ 4.5 sin(26) = EF

∵ sin 26° ≈ 0.44

∴ 4.5(0.44) = EF

∴ 1.98 = EF

The measurement of EF is 1.98 units
