Answer:
see below
Step-by-step explanation:
We know that x > 2 that means the line at x = 2 is dotted since there is no equals sign
We shade to the right since x is greater
Answer:
20
Step-by-step explanation:
24.80-6.80=$18 that's what Britta spent on equal number of carrots and apples because $6.80 was spent on extra carrots only.
18/ .90=20 that means she got 20 apples and 20 carrots before she added $6.80 to buy some extra carrots
Thus, the number of apples Britta bought = 20
Answer:
d) The difference exists due to chance since the test statistic is small
Step-by-step explanation:
From the given information:
Population mean = 178 cm
the sample mean = 177.5 cm
the standard deviation = 2
the sample size = 25
The null hypothesis and the alternative hypothesis can be computed as:
Null hypothesis:

Alternative hypothesis:

The t-test statistics is determined by using the formula:




Degree of freedom df = n- 1
Degree of freedom df = 25 - 1
Degree of freedom df = 24
At the level of significance ∝ = 0.05, the critical value = 2.064
Decision rule: To reject the null hypothesis if the test statistics is greater than the critical value at 0.05 level of significance
Conclusion: We fail to reject the null hypothesis since the test statistics is lesser than the critical value and we conclude that the difference exists due to chance since the test statistic is small
Answer:
0.49 or 49/100
Step-by-step explanation:
So what you have to do here is distribute the 4 to the numbers in the parenthesis next to it. You also have to distribute the 0.5 to the numbers in the parenthesis next to it. So then that would make your equation become 48x-22.4=1.5x+0.35. After this step, you then have to solve for the variable, x. To do this, you would have to go backwards using PEMDAS, so first you add the 22.4 to the other side, making the equation 48x=1.5x+22.75. Then you would subtract 1.5x to the opposite side, makint the equation 46.5x=22.75. Now once you're here, you will divide the 46.5 by 22.75, making x roughly equal 0.49, or if you prefer a fraction form, then 49/100.
