Answer:

<h3>0.0045</h3>

Step-by-step explanation:

0.45\times 0.01

Multiply without the decimal points, then put the decimal point in the answer

45\times \:1=45\\\\\begin{matrix}\space\space&4&5\\ \times \:&\space\space&1\end{matrix}\\\mathrm{Mutliply\:the\:bold\:numbers}:\quad \:5\times \:1=5\\\frac{\begin{matrix}\space\space&4&\textbf{5}\\ \times \:&\space\space&\textbf{1}\end{matrix}}{\begin{matrix}\space\space&\space\space&5\end{matrix}}\\\\\mathrm{Mutliply\:the\:bold\:numbers}:\quad \:4\times \:1=4\\\frac{\begin{matrix}\space\space&\textbf{4}&5\\ \times \:&\space\space&\textbf{1}\end{matrix}}{\begin{matrix}\space\space&4&5\end{matrix}}

0.45\mathrm{\:has\:}2\mathrm{\:decimal\:places}\\0.01\mathrm{\:has\:}2\mathrm{\:decimal\:places}\\\\\mathrm{Therefore,\:the\:answer\:has\:}4\mathrm{\:decimal\:places}\\\\=0.0045

Genetically modified foods: According to a 2014 Pew Research survey, a majority of the American general public (57%) says that g
Soloha48 [4]

Answer:

Option B is correct.

If we assume that 57% of Americans says that GM foods are generally unsafe to eat, then there is an 8.8% chance that random sample results will show 60% or more who says that GM foods are generally unsafe to eat.

Step-by-step explanation:

In Hypothesis testing, p-value helps to show the significance of one's results.

For hypothesis testing, the first thing to define is the null and alternative hypothesis.

The null hypothesis plays the devil's advocate and is always about the absence of significant difference between two variables being compared.

While, the alternative hypothesis takes the other side of the hypothesis; that there is indeed a significant difference between two proportions being compared.

For this question, the null hypothesis is that 57% of Americans say that GM foods are generally unsafe to eat.

H₀: p = 0.57

And the alternative hypothesis would be that more than 57% of Americans say that GM foods are generally unsafe to eat.

Hₐ: p > 0.57

The p-value is actually defined as the probability of obtaining results as extreme as the observed results in the statistical analysis provided that the null hypothesis is true.

For this question , it is evident that the p-value (0.088) is expressing the probability of getting results as extreme as 60% or more Americans saying that GM foods are unsafe to eat provided that the null hypothesis (57% of Americans say that GM foods are generally unsafe to eat) is true.

Hope this Helps!!!

A baker had 24 boxes for donuts he ended up making 526 donuts and splitting them evenly between the boxes how many extra donuts
sertanlavr [38]

Answer:

The baker ended up with 22 extra donuts.

Step-by-step explanation:

Since the baker had 24 boxes and made 526 donuts, to split them evenly between the total number of boxes means that we need to divide the number of total donuts by the number of boxes:

526 ÷ 24 = 21 remainder of 22

Since 24 x 21 = 504 and 24 x 22 = 528 and the baker only made 526 donuts, then the most amount of donuts he can use to split them evenly with the total amount of 526 is 504.  526 - 504 = 22, so he has an extra 22 donuts that will not be in boxes.
