Answer:
The last one 
.
Step-by-step explanation:
1) There are three trigonometric ratios for right-angled triangles.
In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.
2) In this case, we are given a length and an angle to find x and y.
Let's find x first. To find x we need to use 
.
Find y.
Notice that, we can use the Pythagorean Theorem 
to find y.
3) Round them off to the nearest tenth.
Therefore, the correct choice is the last one .
Answer:The pyramid had sloping sides so that the dead pharaoh could symbolically climb to the sky and live forever. The pyramid represented the rays of the Sun I hope this helps
Step-by-step explanation:
B. is true. 15·(–5) > 23·(–12).
15·(-5)=-75.
23·(-12)=-276.
-75 > -276
Answer:
Given: Length of smaller cube= 1/4 feet each side
Length of larger cube= 3.75 feet
Width of larger cube= 3 feet
Height of larger cube= 3.25 feet
Step-by-step explanation:
Volume of a cube= length * width * height
Volume of a larger cube= 3.75 * 3 * 3.25 cubic foot
Volume=36.5625 cubic foot
Volume of smaller cube= length * length * length (as length is same on each side)
Volume of smaller cube= 1/4 * 1/4 * 1/4
Volume of smaller cube= 1/64 cubic foot
Hence, volume is calculated.
range is 31.5, variance is 161.3 and standard deviation is 12.7 for a sample of top 10 annual TV personalities.
Step-by-step explanation:
- Average is mid-point is the mid-point of the data but can skew....
- On the Left or Right is there are higher or lower values.
- Range is difference between maximum and minimum value of data.
- Variance, measure of variability of data but squared or mean deviation.
- Standard deviation is the most important variability.
- It helps in finding out variability with 3 sigma deviations.
- Standard deviation is square root of variance and each sigma explains...
- The data lieing between or within the extreme values.
