Answer:
2. The answer should be the last one.
3. The answer should be the first three.
Step-by-step explanation:
<u>Question 2</u>
KE = (1/2)mv²
2KE = mv²
v² = 2KE/m
v = ±√(2KE/m)
Therefore the answer should be the last one.
<u>Question 3</u>
b^(1/2) * b^(5/2)
Remember that the <u><em>product rule</em></u> states that b^x * b^y = b^(x+y)
So this means b^(1/2) * b^(5/2) = b^(1/2+5/2) = b^(6/2) = b^3
Also remember that the <u><em>power rule</em></u> states that √b = b^(1/2)
so this means b^(6/2) can also be written as (√b)^6
Therefore the answer should be the first three.
<em>If you want to double check all of your answers, just replace b with a number (for example, 2), and plug all of the choices into the calculator. Just </em><u><em>make sure</em></u><em> you are </em><u><em>very careful</em></u><em> when typing into the calculator.</em>
120 dived by 3 multiplied by 2 is equal to 80 packs of crisps
Answer:
More than one triangle because it has to measure up to 180°
81 + 52 + 47 = 180

Answer:
a) There are no evidence that Calvin is correct.
b) There are evidence that Calvin is correct.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 1 ounce
Sample size, n = 23
First, we design the null and the alternate hypothesis
P-value = 0.086
a) Significance level = 5% = 0.05
Since
P-value > Significance level
We fail to reject the null hypothesis and accept it. Thus, the chips bag contain one ounce of product. Thus, there are no evidence that Calvin is correct.
b) Significance level = 10% = 0.10
Since
P-value < Significance level
We reject the null hypothesis and accept the alternate hypothesis. Thus, the chips bag contain less than one ounce of product. Thus, there are evidence that Calvin is correct.
