Answer:
36 tiles
Step-by-step explanation:
First, find area of the square floor knowing the formula as;
Area=
where s= side of a square.
If one side of the floor is 12 feet, then Area=
Next, find the area of each tile using the same formula and given s=2 feet;
Area(tile) =
To find the number of tiles needed to cover entire floor, divide area of the floor by area of one tile; 144 / 4 = 36 tiles
Answer:
The claim on the M&M’s website is not true.
Step-by-step explanation:
A Chi-square test for goodness of fit will be used in this case.
The hypothesis can be defined as:
<em>H</em>₀: The observed frequencies are same as the expected frequencies.
<em>Hₐ</em>: The observed frequencies are not same as the expected frequencies.
The test statistic is given as follows:
Here,
= Observed frequencies
= Expected frequency.
The chi-square test statistic value is, 14.433.
The degrees of freedom is:
df = <em>k</em> - 1 = 6 - 1 = 5
Compute the <em>p</em>-value as follows:
*Use a Chi-square table.
The significance level is, <em>α</em> = 0.05.
p-value = 0.013 < <em>α</em> = 0.05.
So, the null hypothesis will be rejected at 5% significance level.
Thus, concluding that the claim on the M&M’s website is not true.
Answer:
Step-by-step explanation:
Recursive sequences generally look like this:
a1 = something
an= ahhhhhh
The 1st term in this sequence is 11.
So we have
a1=11
And now we see that each term is adding by 22.
We have,
a1=11
