Answer:
-1/3
Step-by-step explanation:
-10(3x)=10
-30x=10
x=10/-30
x=-1/3
Answer:
Option c
Step-by-step explanation:
In Statistics, both t and z tests are used for testing of hypothesis.
Whenever we have sample sizes >30 and when we know population std deviation sigma, we use Z test.
i.e. if sigma is known, we check whether sample size >30 then we use z test
Otherwise if population std deviation is not known, we use t test.
Even if population std deviation is known, if n <30 we use t test. Both use the same formula for std error.
Hence the correct option is option c.
All 4 sides of a square are the same length.
If the perimeter of the square is 20-ft, then each side is 20-ft/4 = 5 ft.
If you increase the length of the square by 2-ft, then its new length is 5+2 = 7-ft.
If you decrease the width of the square by 1-ft, then its new width is 5-1 = 4-ft.
The area of the new figure is (length) x (width) = (7-ft x 4-ft) = <u>28 square feet</u>.
