Answer:
a = 7
Step-by-step explanation:
Using Pythagoras' identity in the right triangle,
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + b² = c² , substitute values
a² + 2.4² = 7.4², that is
a² + 5.76 = 54.76 ( subtract 5.76 from both sides )
a² = 49 ( take the square root of both sides )
a = = 7
The first one is a. If you solve for x, equals 50. And if you retrace the steps described in a, describes the situation. Lost half, then one more.
The second is c, the inequality describes the condition and solves how many commissions he needs to earn at least 100 or more dollars a day.
Let the initial money be x so by question,
3x/5 +1x/5+1200=x
or, 1200= x - 4x/5
or, 1200 = 1x/5
or, 6000= x
hence the initial money was 6000$
For every second the water runs it rises 15 mm and the slope of the graph is 15.
Answer:
At 0.10 significance level, reject H0
At 0.05 significance level, reject H0
At 0.01 significance level, fail to reject H0
At 0.001 significance level, fail to reject H0
Step-by-step explanation:
The null hypothesis is rejected if the p-value is less than or equal to the significance level.
Fail to reject the null hypothesis if the p-value is greater than the significance level.
At 0.1 and 0.05 significance level, the null hypothesis is rejected because the p-value (0.0174) is less than the significance levels.
At 0.01 and 0.001 significance level, fail to reject the null hypothesis because the p-value (0.0174) is greater than the significance levels.
