Answer:
<em>f( g ( - 2 ) ) = - 14 </em>
Step-by-step explanation:
f(x) = - 2x + 4
g(x) = 3x² - x - 5
f( g ( - 2 ) ) = ?
g( - 2 ) = 3( - 2 )² - ( - 2 ) - 5 = 12 + 2 - 5 = 9
f(9) = - 2 × 9 + 4 = - 14
<em>f( g ( - 2 ) ) = - 14</em>
Answer: 7/24
Step-by-step explanation:
Fraction of the items barbecued that are veggie burgers = 3/8
Fraction of the items barbecued that are corn cobs = 1/3
The fraction of the items barbecued that are mushrooms caps will be:
= 1 - (3/8 + 1/3)
The lowest common multiple of 8 and 3 is 24.
= 1 - (3/8 + 1/3)
= 1 - [(3/8 × 24) + [(1/3 × 24)]
= 1 - (9/24 + 8/24)
= 1 - 17/24
= 7/24
Answer:
Sampling is necessary because researchers in the social sciences almost never have enough resources — time or money — to collect information about the entire set of subjects of interest to them.
Step-by-step explanation:
Sampling is done because you usually cannot gather data from the entire population. Even in relatively small populations, the data may be needed urgently, and including everyone in the population in your data collection may take too long.
Answer:
Place "SUM" at 4 on the number line.
Step-by-step explanation:
8 + (-4) = 8 - 4 = 4
Adding a negative number is the same as subtracting its opposite. Adding -4 is the same as subtracting 4.
The answer is the hypotenuse has a length of 5.
