a
The percentage is
b
The probability is
Step-by-step explanation:
From the question we are told that
The population mean is
The variance is
The range consider is
The value consider in second question is
Generally the standard deviation is mathematically represented as
substituting value
The percentage of a cucumber give the crop amount between 778 and 834 kg is mathematically represented as
Generally
So
From the z-table the value for
and
So
The percentage is
The probability of cucumber give the crop exceed 900 kg is mathematically represented as
substituting values
From the z-table the value for
There’s no picture attached!
but the first would point down, and passes through the y axis (up and down) at positive 3
the second points down but goes through the y axis at negative 3 (-3)
the third points up and goes through the y axis at positive 3
the fourth points up and goes through the y axis at negative 3 (-3)
Answer:
10\frac{7}{12}
Step-by-step explanation:
First thing you want to do is find the common denominator for \frac{1}{3} and \frac{3}{4}. You do this by multiplying to denominators together, so 3*4=12.
Next, multiple the numerators with the opposite denominator. 1*4=4 and 3*3=9.
Now you are left with \frac{4][12] and \frac{9}{12}.
Add those back to your numbers
16\frac{4}{12} - 5\frac{9}{12} = 10\frac{7}{12}
Answer:
See below.
Step-by-step explanation:
Lets take √72:
Factoring 72 to find perfect squares:
72 = 2*2*2*3*3
The largest perfect square in the above = 2*2*3*3 = 36.
So we can write 72 as 36*2.
√72 = √(36 * 2)
√36 * √2
= 6√2.
One more example:
√18 = √(2*3*3)
= √9*√2
= 3√2.
