Answer:
Yes. The male and female consumers differ in the amounts they spend.
Step-by-step explanation:
We can express the null and alternative hypothesis as:
It is assumed a significance level of 0.05.
The standard deviation of the difference of means is calculated as:
The test statistic is
The degrees of freedom are:
The P-value for t=10.11 is P=0, so it is smaller than the significance level. The null hypothesis is rejected.
We can conclude that male and female consumers differ in the amounts they spend.
Answer:
I think it's y < 3x +1
Step-by-step explanation:
subtract 6x to the right side. that's -2y > -6x - 2. then divide -2 out of y, now you have to flip the sign. Now you have y < 3x + 1
Answer:
Ms. Petno handed out 48. Ms. H handed out 57.
Step-by-step explanation:
First, because she handed out 9 more than Ms. Petno you take away that 9 from the total number of students. This will give you an even amount that they served combined. 105 - 9 = 96. Then divide by 2 to find out what they both gave out without the extra 9 she handed out. 96 / 2 = 48. Now you know that they both served 48 breakfasts without the extra 9 added on for Ms. H. Finally you add back on the 9 extra to Ms. H. 48 + 9 = 57.
This gives you with Ms. H handed out 57 breakfasts while Ms. Petno handed out 48.
57 + 48 = 105
One way is to divide 500 by 0.15
500/0.15=3333.3333333
the answer is about 3333 times
