Which expression are equivalent to 2(4f+2g)

Cloud [144]

Answer:

8f+4g

Step-by-step explanation:

You have to distribute 2 to each number in the parentheses 2 times 4 is 8 and since 4 has a variable it is 8f and 2 times 2 is 4 and since 2 has a variable it is 4g. We don't combine the two because they have different variables. So the answer is 8f+4g. Hope this helped :)

Suppose that in a random selection of 100 colored candies, 26% of them are blue. The candy company claims that the percentage

quester [9]

Answer: a) -0.2252, b) 0.8219

Step-by-step explanation:

Since we have given that

Sample size n = 100

Probability that candies are blue = p= 0.26

Probability that company claims that it is blue candy = P = 0.27

So, Q = 1-P= 1-0.27 = 0.73

So, Null hypothesis : $H_0:p=P$

Alternate hypothesis : $H_1:p\neq P$

So, the test statistic would be

$z=\dfrac{p-P}{\sqrt{\dfrac{P.Q}{n}}}\\\\z=\dfrac{0.26-0.27}{\sqrt{\dfrac{0.27\times 0.73}{100}}}\\\\z=-0.2252$

Since α = 0.05

So, critical value of z = 1.96

p-value = P(Z>Z(calculated)

Using the excel function , we get that

$P(z>0.2252)\\\\=2\times 0.410.911845\\\\=0.8219$

Hence, a) -0.2252, b) 0.8219

Classify the polynomial by degree and terms. Pick two boxes

Step-by-step explanation:

Sure, that's easy. Although the equation isn't clear to me with characters. I can't seem to figure out whether the x is a multiplication symbol or the variable x. Would you mind writing it on paper and uploading a picture? Then I can help
