Answer:
68 degrees is an acute angle.
Step-by-step explanation:
Answer:
i think 7
Step-by-step explanation:
You don't even have to look up the definition of 'standard deviation'. You only
have to remember that 'smaller standard deviation' means 'less spread-out'.
First, let's find the mean (average). It's not supposed to change:
1/7th of (65 + 71 + 77 + 80 + 82 + 90 + 96) = 561/7 = <u>80 and 1/7</u> .
Now, just pick 7 scores that total 561 and are all bunched up.
The easiest way would be 80, 80, 80, 80, 80, 80, 81 .
But that's so easy that it feels like cheating.
Let's say <u>77, 78, 79, 80, 81, 82, and 84</u> .

➷ A) 5 x 2 = 10
The enlarged cube's side length is 10 cm
B) Work out the volume of the original cube:
Volume = 5 x 5 x 5
Volume = 125 cm^3
As it is volume, you have to cube the scale factor
2^3 = 8
Multiply this new scale factor by the volume:
125 x 8 = 1000
The enlarged cube's volume is 1000 cm^3
C) Work out the surface area of the original cube:
S.A = 5 x 5 x 6
S.A = 150 cm^2
As it is area, you have to square the scale factor
2^2 = 4
Multiply this new scale factor by the surface area:
150 x 4 = 600
The enlarged cube's surface area is 600 cm^2
