Harrizon [31]3 years ago
4 0

Answer:

4, 6 and 8

Step-by-step explanation:

The perimeter is the sum of the lengths of the 3 sides, hence

2x + 3x + 4x = 18

9x = 18 ( divide both sides by 9 )

x = 2

The 3 sides have length

2x = 2 × 2 = 4

3x = 3 × 2 = 6

4x = 4 × 2 = 8

Which of the following p values will lead us to reject the null hypothesis if the level of significance equals .05?
V125BC [204]

Answer:

So then our significance level is \alpha=0.05 and we need to remember these two conditions:

1) If the p value p_v we have enough evidence to reject the null hypothesis at the significance level given

2) If the p value p_v \geq \alpha we have enough evidence to FAIL reject the null hypothesis at the significance level given

And baed on the options we see that the only possibility would be:

d. 0.015

Step-by-step explanation:

We want to know for which value we would REJECT the null hypothesis.

So then our significance level is \alpha=0.05 and we need to remember these two conditions:

1) If the p value p_v we have enough evidence to reject the null hypothesis at the significance level given

2) If the p value p_v \geq \alpha we have enough evidence to FAIL reject the null hypothesis at the significance level given

[Probability / Statistics) Twenty families were surveyed. How many have boys only? ​
Snowcat [4.5K]

Answer:

5

Step-by-step explanation:

We start by seeing how many families we have in total, which is 20. We then must subtract the number of families with girls only, the number of families with both boys and girls, and the number of families with no children. 20 - 7 is 13, then 13 - 8 is 5, and 5 - 0 is 5.
