Answer: 0.42
Step-by-step explanation:
Max accidently mixed 56 turnip seeds and 78 cabbage seeds together because the two seeds look nearly
identical. The probability of choosing a turnips seed will be:
Turnip seed= 56
Cabbage seeds= 78
Total seeds= 56+78 = 134
Probability of choosing a turnips seed:
= 56/134
= 0.42
Suppose the one's digit is x, the ten's digit is y. the original number is 10y+x, the reversed number is 10x+y
x+y=13
(10x+y)=(10y+x)-9 =>9y-9x=9 =>y-x=1
Add the two equation to solve: 2y=14 =>y=7
x=13-7=6
the original number is 76.
Answer:
The percent of these mothers are between the ages 30-35 is 36.53%
Step-by-step explanation:
we are given
mean of age =31.7 years
standard deviation of 5.2 years
For age=30 years:
x=30
we can find z-score
we can plug values
For age=35 years:
x=35
we can find z-score
we can plug values
now, we can use normal distribution table
now, we can find percentage
=36.53%
Answer:
Associative Property
Step-by-step explanation:
The associative property lets us change the grouping, or move grouping symbols (parentheses).
Answer: The "independent variable" is the "time" (in hours) that is plotted on the "x-axis". Note the "time" (in hours) can be "manipulated" in the sense that is it "chosen" by the humans who are measuring the data (e.g. when to start, how many hours, and at what intervals.
The "dependent variable" is the measurement (in feet) above or below the sea level, and this is plotted on the "y-axis". These values cannot be "manipulated" in the sense that one cannot "choose" what value or measurement the tide level would be at any particular time.
Hope these answers—and explanations—are of help to you.
Best wishes!
