Answer:
<em>The probability that the next flower seed will sprout is 0.667 or 66.7%</em>
Step-by-step explanation:
<u>Probability</u>
The experimental or empirical probability can be defined as the ratio of the number of times an event occurs to the total number of times the random activity was performed.
It can be calculated as the relative frequency of an event A in a sample space. The question states 32 seeds of a certain flower sprout out of 48 planted seeds. The relative frequency of success is computed as
Thus, the probability that the next flower seed will sprout is 0.667 or 66.7%

The correct answer is C.
Perpendicular lines have opposite reciprocal slopes. This mean you will flip the original number upside down, and change its sign (negative to positive and vice versa). So, the opposite of -1/4 will be 4.

Answer:
each has to work 5 hours and earn $42
Step-by-step explanation:
Let m and h represent hours Nai spends mowing and hauling, respectively. Then (m+h) will be the number of hours Priya spends babysitting. In order for their earnings to be equal, we must have ...
7m +14h = 8.40(m+h)
5.60h = 1.40m . . . . . . . . subtract 7m+8.40h
m = 4h . . . . . . . . . . . . . . divide by 1.40
Then the total number of hours worked by either person is ...
m + h = (4h) +h = 5h
If only whole numbers of hours are worked, then the smallest number of hours that will make earnings equal is 5h, with h=1, or 5 hours. In that time, each will earn 5×$8.40 = $42.
Each must work 5 hours and earn $42 before they go to the movies.
__
Nai will work 4 hours mowing and 1 hour hauling.
