Mathematics

1 answer:

madam [21]3 years ago

7 0

Answer:

The answer is 11.

Step-by-step explanation:

We will use PEMDAS in this situation.

7 + 2 = x - 4 / 2

7 + 2 = x - 2 [divide first

9 = x - 2 [add the 7 and 2]

+2 +2 [the 2 cancels out]

11 = x

Your answer is 11.

I hope this helped!

Data on the blood cholesterol levels of 6 rats give mean = 85, s= 12. A 95% confidence interval for the mean blood cholesterol o

lana [24]

The <em><u>correct answer</u></em> is:

c)75.4 to 94.6

Explanation:

The formula for a confidence interval is:

$\mu \pm z*(\frac{\sigma}{\sqrt{n}})$ ,

where μ is the mean, z is the z-score associated with the level of confidence we want, σ is the standard deviation, and n is the sample size.

Our mean is 85, our standard deviation is 12, our sample size is 6, and since we want 95% confidence, our z-score is 1.96:

$85\pm 1.96(\frac{12}{\sqrt{6}})=85\pm 9.6=85-9.6, 85+9.6=75.4, 94.6$

Determine the value of B such that the line defined by 8x + By + 92 = 0 passes through the point (-4,12).

zvonat [6]

8x + By + 92 = 0

(-4; 12) ⇒ x = -4; y = 12

subtitute

8 · (-4) + 12B + 92 = 0
-32 + 12B + 92 = 0
12B + 60 = 0 |subtract 60 from both sides
12B = -60 |divide both sides by 12

B = -5
