PLEASE ANSWER ASAP!!! CORRECT ANSWER PLEASE!!!
Elden [556K]
To find a perpendicular line, the slope is opposite reciprocal. The slope would be -4x.
Put in point slope form:
y - 7 = -4(x - 2)
y - 7 = -4x + 8

y = -4x + 15
(line perpendicular to given equation and goes through the point)

Hope this helps!! :)

A random sample of 10 chocolate energy bars of a certain brand has, on average, 230 calories per bar, with a standard deviation
Troyanec [42]

Answer:

The confidence interval for the true mean calorie content is

215

Step-by-step explanation:

In this problem we know the mean and standard deviation fo the sample, so we can compute the CI like this:

\bar{x}-t*s/\sqrt{n}< \mu

We need to determine t for 10-1=9 degrees of freedom and 99% confidence level. We look up in the t-table and the value for t is 3.2498.

Then we can calculate the limits of the CI:

\bar{x}-t*s/\sqrt{n}< \mu

If the sum of squares for a sample containing 51 items equals 200, what is the standard deviation?
Mashcka [7]

The standard deviation is 1.98. Option A is correct.

The standard deviation formula is given as

  • \sigma = \sqrt{\frac{SS}{n} }

where:

  • SS is the sum of squares = 200
  • n is the sample size = 51

Substitute the given parameters into the formula to have:

\sigma = \sqrt{\frac{200}{51} }\\\sigma = \sqrt{3.922}\\\sigma = 1.980

Hence the standard deviation is 1.98
