43% adults favor the use of unmanned drones by police agencies. Twelve U.S. adults are randomly selected. Find the probability that the number of U.S. adults who favor theuse of unmanned drones by police agencies is (a) exactly three, (b) at least four, (c) less than eight(a) P(3) =(Round to three decimal places as needed.)
EXPLANATION:
According to the established pattern that only 43 out of 100 adults favor the use of drones, now we must find out from the only twelve adults surveyed how much corresponds to 43 percent.
The first thing we must do is make the relation 12 equals 100, then 43 percent how much?
[tex]\begin{gathered} 12\rightarrow100 \\ x\leftarrow43 \\ x=\frac{12\times43}{100} \\ \textcolor{#FF7968}{x=5.16}\text{\textcolor{#FF7968}{ ; }} \\ \text{the answer is }\text{\textcolor{#FF7968}{5.16 }}\textcolor{#FF7968}{that}\text{\textcolor{#FF7968}{ is less than eight }}\text{; } \end{gathered}[/tex]help me please im not understanding on the right side it says: to the total number of people present. Express as a simplified ratio
ANSWER
4 : 9
EXPLANATION
The total number of people present is the number of females plus the number of males:
[tex]125+100=225[/tex]The ratio of number of males to total number of people is:
[tex]\frac{100}{225}[/tex]We have to simplify this fraction. Both 100 and 225 are divisible by 5:
[tex]\begin{gathered} 100\colon5=20 \\ 225\colon5=45 \end{gathered}[/tex]Therefore:
[tex]\frac{100}{225}=\frac{20}{45}[/tex]And then again, 20 and 45 are divisible by 5:
[tex]\begin{gathered} 20\colon5=4 \\ 45\colon5=9 \end{gathered}[/tex]Therefore:
[tex]\frac{100}{225}=\frac{20}{45}=\frac{4}{9}[/tex]We can't simplify more than that, so the ratio is 4 : 9

So now you must give thepopulation standard deviationPopulation Standard Deviation?
The formula to find the mean of a data set is:
[tex]\begin{gathered} \bar{x}=\frac{\text{Sum of all the items}}{\text{ Number of items}} \\ \text{ Where }\bar{\text{x}}\text{ is the mean of a sample} \end{gathered}[/tex]So, in this case, we have:
[tex]\begin{gathered} \bar{x}=\frac{23.5+42.1+31.1+16.3+21.1+32.1+44.8+13.5+29.9}{9} \\ \bar{x}=\frac{254.4}{9} \\ \bar{x}=28.27 \end{gathered}[/tex]Therefore, the mean of the given data set rounded to two decimal places is 28.27.
Standard deviationThe sample standard deviation formula is:
[tex]\begin{gathered} s=\sqrt[]{\frac{\sum ^n_{i\mathop=1}(x_i-\bar{x})^2}{n-1}} \\ \text{ Where} \\ \text{ n is the number of data points} \\ x_i\text{ is each of the values of the data} \\ \bar{x}\text{ is the mean of the data set} \end{gathered}[/tex]So, in this case, we have:
[tex]\begin{gathered} s=\sqrt[]{\frac{(23.5-28.27)^2+(42.1-28.27)^2+(31.1-28.27)^2+(16.13-28.27)^2+(21.1-28.27)^2+(32.1-28.27)^2+(44.8-28.27)^2+(13.5-28.27)^2+(29.9-28.27)^2}{8}} \\ s=\sqrt[]{\frac{(-4.77)^2+(13.83)^2+(2.83)^2+(-11.97)^2+(-7.17)^2+(3.83)^2+(16.53)^2+(-14.77)^2+(1.63)^2}{8}} \\ s=\sqrt[]{\frac{22.72+191.36+8.03+143.2+51.36+14.69+273.35+218.05+2.67}{8}} \\ s=\sqrt[]{\frac{925.44}{8}} \\ s=\sqrt[]{115.68} \\ s=10.76 \end{gathered}[/tex]Therefore, the sample standard deviation of the given dataset rounded to two decimal places is 10.76.
VarianceThe standard deviation is the square root of the variance. Thus, the formula to find the variance of a sample is,
[tex]s^2=\frac{\sum^n_{i\mathop{=}1}(x_i-\bar{x})^2}{n-1}[/tex]So, in this case, we have:
[tex]s^2=115.68[/tex]Therefore, the sample variance of the given dataset rounded to two decimal places is 115.68.
PopulationStandard deviationThe population standard deviation formula is:
[tex]\begin{gathered} \sigma=\sqrt[]{\frac{\sum ^n_{i\mathop{=}1}(x_i-\bar{x})^2}{N}} \\ \text{Where} \\ \sigma\text{ is the population standard deviation} \\ x_i\text{ is each of the values of the data} \\ N\text{ is the number of data points} \end{gathered}[/tex]So, in this case, we have:
[tex]\begin{gathered} s=\sqrt[]{\frac{(23.5-28.27)^2+(42.1-28.27)^2+(31.1-28.27)^2+(16.13-28.27)^2+(21.1-28.27)^2+(32.1-28.27)^2+(44.8-28.27)^2+(13.5-28.27)^2+(29.9-28.27)^2}{9}} \\ s=\sqrt[]{\frac{(-4.77)^2+(13.83)^2+(2.83)^2+(-11.97)^2+(-7.17)^2+(3.83)^2+(16.53)^2+(-14.77)^2+(1.63)^2}{9}} \\ s=\sqrt[]{\frac{22.72+191.36+8.03+143.2+51.36+14.69+273.35+218.05+2.67}{9}} \\ s=\sqrt[]{\frac{925.44}{9}} \\ s=\sqrt[]{102.83} \\ s=10.14 \end{gathered}[/tex]Therefore, the population standard deviation of the given dataset rounded to two decimal places is 10.14.

Question 3 of 10A digital scale reports a 10 kg weight as weighing 8.975 kg. Which of thefollowing is true?A. The scale is precise but not accurate.B. The scale is accurate but not precise.OC. The scale is neither precise nor accurate.O D. The scale is both accurate and precise.SUBMIT
Solution:
The real weight is 10kg;
But the digital scale reports 8.975kg.
Thus;
Accuracy refers to the closeness of the measure to the real value, while precision, in this case, refers to the level of significant figures that the scale report.
The fact that the scale reports the number with 4 significant figures means that it is very precise, but we still observe that the report is not so close to the real value, thus, it means that the scale is not accurate.
FINAL ANSWER: A. The scale is precise but not accurate

Identify the coefficient and the exponent for each term
Answer:
Coefficients are 6 and 4. The exponents are 3 and 1.
Step-by-step explanation:
The coefficient of a term is the number next to variable, the number that the variable is multiplied by.
Remember that if you are subtracting by a term, you are adding the "negative" term.
Meaning:
6x³ - 4x = 6x³ + (-4x)
The exponent of a term is the power (the little number on top). When the exponent (power) is not shown, it is just 1.
Meaning:
-4x = -4x¹
Mick O'Meara budgeted $315 per month for electricity and $238 per month for gas. His expenses for a twelve-month period were $3,950 for electricity and $3,055 for gas.How much less did he budget annually for the two expenses than he needed?$339$344$357$369None of these choices are correct.
In order to know how much he budgeted annually for each expense, we need to multiply each month budget by 12:
annual budget for electricity: 12 * 315 = 3780
annual budget for gas: 12 * 238 = 2856
So, the total annual budget was:
3780 + 2856 = 6636
On the other hand, his real expenses for that year were:
3950 + 3055 = 7005
Then, to find how much less he budget than he needed, we can find the difference between those two values:
7005 - 6636 = 369
Therefore, the last option is correct.

A sporting goods store charges $22.00 for a football before tax. The store holds a sale that marks all prices down by 20% before tax. If the sales tax is 5%, what is the cost of the discounted football after tax?
The cost of the discounted football after applying the tax is $18.48
Discount:
Discount refers the difference between the price paid for and it's par value. Discount is a sort of reduction or deduction in the cost price of a product.
Given,
A sporting goods store charges $22.00 for a football before tax. The store holds a sale that marks all prices down by 20% before tax.
Here we need to calculate the cost of the discounted football after the tax of 5%.
We know that the cost of the football is $22.00 before tax.
So, if we apply the discount of 20% on it , then the cost of the foot ball is,
Discount = 22 x 20/100
Discount = 4.4
So, the cost of the foot ball after discount is,
=> 22 - 4.4
=> 17.6
Now, we have to apply the tax 5% on it, then we get,
=> 17.6 x 5/100
=> 17.6 x 0.05
=> 0.88
Therefore, the cost of the discounted football after the tax of 5% is.
=> 17.6 +0.88
=> 18.48

find the slope of a line that is PARALLEL to y=3/5x-2
Parallel lines have the same slope.
In this case, the slope of the line is 3/5.
Then, any line that satisfies y=3/5*x+C, being C any constant, is parallel to our line.
Then, when C=0 for example, we have the line y=3/5*x that is parallel and goes through the center of coordinates (0,0).
Graphically, we can see that they a re parallel:
Answer: y = 3/5*x + C, with C=constant. There are infinte solutions if no other restriction is made, so for example y=3/5*x is parallel to y=3/5*x-2.
