Last Option: "The division property is used to create step 4" is the correct answer

Step-by-step explanation:

Given equation is:

$6(3x-4)-26 = 40$

Step 1: Distributive property

$18x-24-26 = 40\\$

Step 2: Simplifying

$18x-50 = 40$

Step 3: Addition Property of Equality

$18x-50+50 = 40+50\\18x = 90$

Step 4: Division Property of Equality

$\frac{18x}{18} = \frac{90}{18}\\x = 5$

Hence,

Statistics Question

The p-value is used to decide whether to reject or fail to reject the null hypothesis

Step-by-step explanation:

The p-value is used to make a conclusion in significance testing.

Where the p-value is lower than the significance value adopted ∝, you reject the null hypothesis H₀. In such a case, p-vale<∝⇒reject H₀⇒accept Hₐ.

Where the p-value is greater than or equal to the significant level ∝, you fail to reject the null hypothesis H₀, to mean p-value≥∝⇒fail to reject H₀

I don’t understand how to do this problem. How would I solve it?

artcher [175]

Answer:

About 2.569 seconds

Step-by-step explanation:

To solve this problem, you can separate it into two half parabolas. The beginning part is initial upward rising. To calculate the amount of time that this part of the dive takes, you can use the formula $v_f=v_o+at$ , where $v_f$ is the final velocity, $v_o$ is the initial velocity, a is the acceleration due to gravity, and t is the amount of time it takes. You know that the final velocity is 0, since the diver is reaching the terminal of their dive. Therefore, you can set up the following equation (assuming that the acceleration due to gravity is 32ft/s^2):

$0=5+(-32)t$

$t=5/32$ seconds

To find the height that this indicates the diver has risen, you can plug this time into the following formula: $d=v_o t+\frac{1}{2}at^2$

$d=5(5/32)+\frac{1}{2}\cdot 32\cdot (5/32)^2\approx 1.172$ feet

For the second part, you can use the equation $d=v_o t+\frac{1}{2}at^2$ again. Since the initial velocity for this part is 0, you can set up the following equation:

$92+1.172=\frac{1}{2}\cdot 32 \cdot t^2$

$t \approx 2.413$

Adding this to the time that the first part of the dive takes, you get a total of about 2.569 seconds. Hope this helps!
