Which equation represents the model shown

Alex787 [66]

Answer:

The answer is A.

Step-by-step explanation:

This is quite the odd question to see on homework, but looking at it a certain way helps determine the answer. two fourths are shaded in, and so is one twelfth. Since the other five twelfths are blank, it can be interpreted that the model is showing us A. This can be checked on a scientific calculator.

.5 / (1/12) = 6

Therefore, A is correct.

Can anyone help me solve this?

Novay_Z [31]

Answer:9

Step-by-step explanation:

Use the pythagorean theorem. $a^{2}+b^{2}=c^{2}$

We know both a and c, so it becomes

$4^{2}+b^{2}=\sqrt{97}^{2}$ =

16+b^2=97=

97-16=b^2=

81=b^2=

9=b

Determine the margin of error in estimating the population mean, μ . A sample of 74 college students yields a mean annual income

Julli [10]

Answer:

$253

Step-by-step explanation:

Margin of error is the critical value times the standard error.

MoE = z × σ/√n

At 99% confidence, z = 2.576.

MoE = 2.576 × 844/√74

MoE = 253
