Answer:
The standard deviation is not greater than 5 mg ()
Step-by-step explanation:
First we need to find the z-score for a 0.05 level of significance.
Looking in the z-table with alpha = 0.05, we have z = 1.645.
Now, finding the standard error of the mean, we have:
The standard deviation with 0.05 level of significance would be:
This deviation is not greater than 5 mg.
Answer:
x < -39
Step-by-step explanation:
d/13 is actually just 1/13d:
1/13d > -3
Then you multiply both sides by the reciprocal of 1/13 which is 13. You do this because you normally you would divide, but since you can't divide a fraction, you multiply by the reciprocal, which is just the flipped version.
13 × 1/13 > -3 × 13
It cancels out on one side, because you are multiplying by its opposite. Then you multiply 13 × -3. This is -39. But the thing is that, when you multiply or divide by a negative, you need to flip the inequality sign around.
x < -39
Answer:
c.10 square units
Step-by-step explanation:
Area of Triangle = 1/2(x1(y2−y3)+x2(y3−y1)+x3(y1−y2))
substitute the coordinates in the formula and take modulus ( so that the answer becomes positive )
I hope you understood , cheers mate !!
Answer:
A
Step-by-step explanation:
Given
3
When the culture was created t = 0, thus
3 = 3 × 1 = 3
That is there were initially 3 bacteria in the culture → A
Yes 2+2=4-3=1 its quick mathss
