If a spinner for a game is spun once, there is a 25% chance it will land on

bonufazy [111]

Answer:

$Pr = 0.6$

Step-by-step explanation:

Given

Let

$O \to Orange$

So:

$P(O) = 25\%$ --- probability of O

$n=2$ --- Number of spin

Using the complement rule, the probability that a spin will not land on orange is:

$P(O') = 1 - P(O)$

$P(O') = 1 - 25\%$

Express as decimal

$P(O') = 1 - 0.25$

$P(O') = 0.75$

On two spins, the probability that it will not land on orange is:

$Pr = P(O') * P(O')$

So, we have:

$Pr = 0.75* 0.75$

$Pr = 0.5625$

$Pr = 0.6$ --- approximated

Nat2105 [25]

Question:

Hector has a floor plan showing his new house. On the floor plan, his bedroom is 3 inches wide and 3 1/2 inches long. The scale of the floor plan is 1/4 inch = 1 foot. What is the actual length of Hector’s room?

Answer:

The actual length of Hector room is 14 foot

Solution:

Given that, On the floor plan, his bedroom is 3 inches wide and $3\frac{1}{2}$ inches long

The scale of floor plan is given as:

$\frac{1}{4} \text{ inch} = 1 \text{ foot }$

Therefore,

$1 \text{ inch } = 4 \text{ foot}$

To find: Actual length of floor

From given question,

$length = 3\frac{1}{2} \text{ inches}$

Converting the mixed fraction to improper fraction,

$length = \frac{2 \times 3 + 1}{2} = \frac{7}{2} \text{ inches }$

Since, 1 inch = 4 foot

$\frac{7}{2} \text{ inches } = \frac{7}{2} \times 4 \text{ foot } = 14 \text{ foot }$

Thus actual length of Hector room is 14 foot
