Answer:
D: A prediction based on data is reliable, because the means of the samples are close together.
Step-by-step explanation:
I got it right:)
For this case we must find an expression equivalent to:
To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:
If we run the decimal 9 spaces to the left we have:
Option B:
We discard it because the exponent is negative.
Option C:
We run the decimal 6 spaces to the right
Option D:
We run the decimal 9 spaces to the right
Answer:
Option D
P= IRT solve for T To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side. IRT means that I and R are multiplied by T. To get rid of them we must do the opposite of multiply, which is divide. But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side. So if we divide the right side by IR, we must also divide the left side by IR

Answer:
x < -3/2
Step-by-step explanation:
12x + 7 < -11
Subtract 7 to both sides
12x < -11 -7
= 12x < -18
Solve for x.
x < -18/12
= x < -3/2
