Answer:

Mya wrote two expressions that are not equivalent

Step-by-step explanation:

45 +72 does not equal to 9(5+9)

Answer:

Step-by-step explanation:

I dislike these kinds of questions. I could argue either of 2 answers - b and d.

b says that her error was that she wrote two expressions that are not equivalent and that is true. She did not write equivalent expressions.

d says she didn't use a common factor to both terms and that is true.

The actual answer is that she made a silly error which we all often do.

8 * 9 is 72

so the distributive property should be

9(5 + 8)

So, what's the answer? I would pick D, but hold your nose when you enter it.

Effectus [21]

Answer:

The statement, (1- α)% confidence interval for (μ₁ - μ₂) does not contain zero is TRUE.

Step-by-step explanation:

The hypothesis for a test is defined as follows:

H₀: μ₁ = μ₂ vs. Hₐ: μ₁ ≠ μ₂

It is provided that the test was rejected st the significance level α%.

If a decision is to made using the confidence interval the conditions are:

If the null hypothesis value is not included in the (1 - α)% confidence interval then the null hypothesis will be rejected and vice versa.

In this case the null hypothesis value is:

H₀: μ₁ - μ₂ = 0.

If the value 0 is not included in the (1 - α)% confidence interval for the difference between two means, then the null hypothesis will be rejected.

Thus the statement, (1- α)% confidence interval for (μ1- μ2) does not contain zero is TRUE.

Answer:

8 units

Step-by-step explanation:

so there is something called Pythagorean thereon and it states that a^2+b^2=c^2

and 6 is either a or b

and c is ten so

6^2+b^2=10^2

36+b^2=100

b^2=64

here you need to find the square root in order to delete the power so

$\sqrt{b} =\sqrt{64\\\\$

b=8

x=8

Step-by-step explanation:

Function of the cylinder is to measure liquid volumes accurately. They are extensively used in chemistry and biology labs, where quantities of accurately measured liquids need to be used. They are purposely designed to be long, with a shorter diameter compared to beakers, to facilitate accurate measurements.
