ANSWER:
d. x = 15, y= 15√3
EXPLANATION:
This is a special triangle, more specifically a 30-60-90 degree triangle. For sake of not confusing x and y, we will use z to use as our reference for solving this triangle. The side lengths for each angle are as follows:
• 60 degrees = z√3
- this is the value for your y answer
• 30 degrees = z
- this is the value for your x answer
• Hypotenuse = 2z
- this is what we already have
We solve for what we already have which is the Hypotenuse = 30:
2x = 30
x = 15
We now have our x value which is 15.
Now we just plug in that x value for every expression for every angle.
x = 15
y = 15√3

Answer:
First one : -4x
Second one : - 6/3 or -2
Step-by-step explanation:
Subtraction on the first one. It brings it down to a negative number.
Second one, change the sign oft the second number then add.
Here is the complete question:
a. Statistically significant at 0.01
b. Not statistically significant
Answer:
The test is significant
Step-by-step explanation:
When a p value is smaller than or less than alpha we say it is statistically significant.
We are testing the p value or likelihood of 0005 against a significant level of 0.01
P value = 0.005 < 0.01
0.005 is less than 0.01 which shows the test to be significant.
The decision rule would be to reject the null hypothesis and say the result is statistically significant.
Answer:
One more transformation – a horizontal stretch – would map ΔDCE onto ΔABE. So the triangles are similar.
Step-by-step explanation:
Rigid transformation involves the applications of some processes and procedures to change the orientation of a given figure. It can either be reflection, translation or rotation. While dilation is the process of resizing a given figure as required.
A horizontal stretching is a transformation that involves changing the position or coordinates of a point along the horizontal axis away from the vertical axis.
Lennox claims he used a sequence of rigid transformations and dilation, but did not perform one more transformation, horizontal stretch, which would make the two triangles to be similar.
