Hi,
1) D
Working :
If the bell rings for 2 weeks straight that means it rings for 14 days.
The bell rings 48 times a day (2 * 24).
The answer is then: 48*14 = 672
2) C
Working:
144 cookies * 8 batches = 864 cookies
864 divided into boxes of 8 = 864 / 8 = 108
Answer:
the bring them to my house kidding its 118
Step-by-step explanation:
Let w be the width of the rectangular board
Let l be the length of the rectangular board.
Given that w = 26cm
∴ l = 26 + 10 = 36cm [∵ length is 10cm longer than width]
Now the board can be cut into 9 equal pieces, each of length 4cm along the length of the board [∵ 9 × 4 = 36]
The width of each of the 9 pieces will remain 26cm.
Answer A : area of each piece is
A = l × w = 4 × 26 =
Answer B : dimension of each piece is
l = 4 cm
w = 26 cm
Answer:
Option A: 3.59% is the correct answer
Step-by-step explanation:
Z-score is used to calculate the probabilities when mean and standard deviation is given.
Given
Mean = μ = 21
SD = σ = 5
We have to find the probability of selling 12 or less water heaters so our x value is 12
x = 12
The z-score of a value is calculated as:
z-score = (x-μ)/σ
Putting the values
Now z-score table will be used to calculate the probability for z= -1.8
So we will go for the row with -1.8 and column 0, which gives us: 0.03593
As we have to calculate the probability in percentage
Hence,
Option A: 3.59% is the correct answer
