All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set up Equation

Every angle must add up to 180°.

(6x - 6)° + 54° + 90° = 180°

Step 2: Solve for x

Combine like terms: 6x + 138 = 180
Isolate x term: 6x = 42
Isolate x: x = 7

The time (in number of days) until maturity of a certain variety of tomato plant is Normally distributed with mean μ. You select

VLD [36.1K]

Answer: 60.93 < μ < 69.07

Step-by-step explanation: The true mean of a set of data is between an interval of values with a percentage of precision, e.g., a 99% confidence interval means we are 99% confident the true mean is between the lower and upper limits.

To find the interval, use

x± $z\frac{s}{\sqrt{n}}$

z is z-score related to the % of confidence level

In this case, a 99% confidence interval is 2.576

x is sample mean

Calculating:

$x=\frac{63+69+62+66}{4}$

x = 65

65± $2.576\frac{3.16}{\sqrt{4}}$

65±4.07

Confidence Interval: 60.93 < μ < 69.07

Meaning that we are 99% sure the population means is between 60.93 and 69.07.
