Step-by-step explanation:
3x + 4 < -7
3x < -7 - 4
3x < -11
x < -11/3 ≈ -3,666
x = {3,2,1,0, etc}
Answer:
A tourist receives 2376 ec currency in exchange for us 1200.
Step-by-step explanation:
This can be calculated as follows:
Tax rate = 1%
Amount of us currency = 1200
Total amount of ec currency = Amount of us currency * 2 = 1200 * 2 = 2400
Amount of tax = Total amount of ec currency * Tax rate = 2400 * 1% = 24
Net amount of ec currency = Total amount of ec currency - Amount of tax = 2400 - 24 = 2376
Net amount ec currency obtained above is the amount of ec currency which a tourist receives in exchange for us 1200.
Therefore, a tourist receives 2376 ec currency in exchange for us 1200.
Answer:
Approximately 68%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 1, standard deviation = 0.05.
Estimate the percent of pails with volumes between 0.95 gallons and 1.05 gallons.
0.95 = 1 - 0.05
1.05 = 1 + 0.05
So within 1 standard deviation of the mean, which by the Empirical Rule, is approximately 68% of values.
Answer:
Step-by-step explanation:
Volume = 4πr³/3
Solid shape is a sphere. r ----> radius
Answer:
1) 2m + 3m2 - 4m=7
7) 3m2 – 2m + 4m= 11
8) 20 + 109 + 39 - 4= 164
3) 2m + 4m - 3m2= -3
9) 4xy + x + 2xy= 0
4) 2y + 14x - 7x + 9y= 18
10) 6m2 - 6m - 9m2= -51
