Answer:
-10
Step-by-step explanation:
This problem uses the intersecting chord theorem. In this case, it states that:
ML * LE = SL * LI
With this knowledge, we can fill in the known values and solve for the unknown ML.
ML * 12 = 4 * 9
ML * 12 = 36
ML = 36/12
ML = 3
Thus, the missing value is 3.
Answer:
24 cm²
Step-by-step explanation:
You can show your sister how to use the formula for the area of a triangle.
The base dimension is substituted for the letter b, the height is substituted for the letter h, and then the arithmetic is carried out.
A = 1/2bh
A = (1/2)(12)(4) = (6)(4) = 24 . . . . square centimeters
Answer:
C. We have made a correct decision
Step-by-step explanation:
Hypotheses are:
: mu is less than or equal to 47
: mu is greater than 47
Type I error happens when we reject the null hypothesis but the null hypothesis was true
Type II error happens when we fail to reject the null hypothesis but the null hypothesis was wrong.
In this example we concluded that <em>mu is greater than 47,</em> thus we reject the null hypothesis. Since true mean is 52, this conclusion is true. We have made a correct decision
