Answer:
The answers is below in bold.
Step-by-step explanation:
(a) A = 180 - 25.6 - 124.4 = 30 degrees.
Next use the Sine Rule:
b / sin B = c / sin C
b / sin 25.6 = 39.2/sin 124.4
b = (39.2 * sin 25.6) / sin 124.4
b = 20.53 m.
Also
a / sin A = c / sin C
a / sin 30 = 39.2 / sin 124.4
a = (39.2 * sin 30 / sin 124.4
a = 23.75 m.
b). This is solved in a similar way to (a).
First find angle C using the sine rule.
Then you will know angle A from the 180 degree Rule.
Then you can find the length of a using the Sine Rule.
Answer:
The correct option are: (A), (B), (C) and (E).
Step-by-step explanation:
The One-Way ANOVA is a statistical test used to compare the three or more population means.
The hypothesis is:
<em>H</em>₀: The population means are equal, i.e. μ₁ = μ₂ = μ₃ =...= μₙ
<em>H</em>ₐ: At least one of the population mean differ.
The Assumptions of One-way ANOVA are:
- The samples selected from each population are independent of each other.
- The population distribution of the dependent variables follow Normal distribution.
- The population variances are always equal for all the groups.
Thus, the correct option are: (A), (B), (C) and (E).
C because drawing the blue marble doesn’t affect drawing the yellow marble because the blue marble was replaced
Answer:
Step-by-step explanation:
AE is 9. ED is 6. The triangle ABE is proportional to ACD, so their sides are proportional. For example, AE:ED = AB:BC. So, ED/AE = 2/3 = BC/AB. This gives us 2/3 = x/10, which gives us x=6.6667
