Answer:
B) 47.5%
Step-by-step explanation:
Refer to the normal distribution chart attached. If 130 is 2 standard deviations higher than the mean (ignore the numbers beneath the percentages), then by the empirical rule, this means that 34%+13.5%=47.5% of adults are between IQs of 100 and 130. Therefore, option B is correct.
Hello!
To find this you have to find what 55% of 20 is
You can do this by doing 20 * 0.55
0.55 is 55% as a decimal
This gives us the answer of 11
Hope this helps!

Answer:
m∠SVW = 80°
Step-by-step explanation:
3. The sum of <em>same-side interior</em> angles SVW (4x°) and VWT (5x°) is 180°. This can be used to solve for x and to find the angle values.
4x + 5x = 180
9x = 180 . . . . . . . . collect terms
x = 20 . . . . . . . . . . divide by 9
m∠SVW = 4x° = 4(20)°
m∠SVW = 80°
_____
4. Then m∠VWT = 180° -80° = 100° = 5x°.
__
5. <em>Consecutive interior</em> angles are supplementary. ("Same-side" and "consecutive" are used interchangeably in this context.)
Carol did not work 1/14 of the days.
1/14*28/1= 28/14=2 days she did not work
Carol worked at the bookstore 1/4 of the days
1/4*28/1= 28/4= 7 days at the bookstore
28-7-2= 19 days that she worked at the restaurant
Final answer: B
