Answer:
The number of pizzas sold during A-
lunch is 64
Step-by-step explanation:
Let us solve the question using the ratio method
∵ The ratio of pizza to nachos sold during A-lunch is 4 to 3
∵ There were 48 nachos sold
→ By using the ratio method
→ Pizza : Nachos
→ 4 : 3
→ x : 48
→ use the cross multiplication
∵ x × 3 = 4 × 48
∴ 3x = 192
→ Divide both sides by 3
∵ 
= 
∴ x = 64
∴ The number of pizzas sold during A-
lunch is 64
The number of favorable outcomes is the the number of the outcome she wants. She wants a silver car. In her table, 36 cars are silver.
a. 36
The total number of trials is the sum of the all numbers of cars.
12 + 9 + 32 + 42 + 36 + 1
b. 132
The experimental probability of an event is the number of desired outcomes divided by the total number of outcomes.
c. p(silver car) = 36/132 = 3/11
d.
An event takes place, and there are only two possible outcomes.
If the probability of one event happening is x, then the probability of the other event happening is 1 - x.
Think of this situation as only two possible outcomes.
Either a silver car passes or a non-silver car passes.
The probability of a silver car passing is 3/11.
Then the probability of a non-silver car passing is 1 - 3/11.
1 - 3/11 = 11/11 - 3/11 = 8/11
Answer:
Step-by-step explanation:
A right angled ∆ is given to us and we need to find out the value of cos 45° ( with rationalized denominator ) . As we know that in a right angle ∆ , the value of cosine is ,
In the given triangle ,
- Value of base = 1
- Value of hypotenuse = √2
On substituting the respective values ,
For rationalizing the denominator , multiply numerator and denominator by √2 , we have,
Simplify ,
Its either 14 or 40 i think
