Answer:
x = 60°
Step-by-step explanation:
G= 90°
30 + 90 = 120
180 - 120 = 60

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
Answer:
To round 2.85 to the nearest hundredth, since there is no number after the hundredth value, the number would remain 2.85
Step-by-step explanation:
the hundredth is the second number after the decimal place. To convert to the nearest hundredth, look at the number after the hundredth (the thousandth). If the number is greater or equal to 5, add 1 to the hundredth figure. If this is not the case, add zero
for example, 2.8561 to the nearest hundredth is 2.86
2.8541 to the nearest hundredth is 2.85
2.85 to the nearest hundredth is 2.85
Multiples of 7 up to 49:
7
14
21
28
35
42
49
Therefore, multiple of 7 occurs seven times.
There are 43 cards altogether.
Therefore, P(multiple of seven)= 7/43
