Question is on the picture/screenshot
Answer:
127
Step-by-step explanation:
Following the Order of Operations, we should subtract 19 - 7 = 12
Then, you do the exponents so, 12 * 12 = 144.
Next, multiply. 8 * 3 = 24 and 4 * 3 = 12
So your equation should look like this. 144 - 24 + 12 - 5
Now from left to right you solve it so, 144 - 24 = 120
144 - 24 = 120
120 + 12 = 132
132 - 5 = 127
Have a wonderful day!

Ms. Parker determined that the mean test score in her first-period class
was 81 with a standard deviation of 7.06. The mean test score in her
second-period class was 88 with a standard deviation of 8.24. Which
conclusion can be made about her students' test scores?
A Period 2 had scores that were less spread out around the mean than
Period 1.
B. Period 1 had scores that were less spread out around the mean than
Period 2.
C. Period 2 had scores that were less spread out around the median than
Period 1.
D
Period 1 had scores that were less spread out around the median than
Period 2.
Answer:
B. Period 1 had scores that were less spread out around the mean than
Period 2
Step-by-step explanation:
Because the standard deviation of Period 2's scores is greater than that of Period 1's, the test scores for Period 2 are going to be more spread out than Period 1's test scores. B is the most logical choice in this case.

If the mean is 4, what is the missing number of the data set: 3, 4, ___, 7, 2, 1.
Answer:
7
Step-by-step explanation:
Let the missing number of the data be x.
[tex] \because mean = \frac{3 + 4 + x + 7 + 2 + 1}{6} \\ \\ \therefore 4 = \frac{17 + x }{6} \\ \\ \therefore 4 \times 6 = 17 + x \\ \\ \therefore 24 - 17 = x \\ \\\therefore x = 7[/tex]
Thus, the missing number of the data is 7.

Consider g (x) = StartFraction 4 x + 9 Over x Superscript 6 Baseline + 1 EndFraction Which statement correctly uses limits to determine the end behavior of g(x)? Limit of StartFraction 4 x + 9 Over x Superscript 6 Baseline + 1 EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 4 Over 1 EndFraction as x approaches plus-or-minus infinity, so as x approaches infinity, g (x) approaches 4. Limit of StartFraction 4 x + 9 Over x Superscript 6 Baseline + 1 EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 4 Over x Superscript 5 EndFraction as x approaches plus-or-minus infinity, so as x approaches infinity, g (x) approaches 4. Limit of StartFraction 4 x + 9 Over x Superscript 6 Baseline + 1 EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 4 Over x Superscript 5 EndFraction as x approaches plus-or-minus infinity, so as x approaches infinity, g (x) approaches 0. Limit of StartFraction 4 x + 9 Over x Superscript 6 Baseline + 1 EndFraction as x approaches plus-or-minus infinity = limit of StartFraction 4 x Over 1 EndFraction as x approaches plus-or-minus infinity, so as x approaches infinity, g (x) approaches infinity.
Answer: C
Step-by-step explanation:
To find the end behavior of a function, we find it's limits as x approaches infinity, getting the correct option as:
As x approaches plus-or-minus infinity = limit of StartFraction 4 Over x Superscript 5 EndFraction as x approaches plus-or-minus infinity, so as x approaches infinity, g (x) approaches 0.
Function:
The function given is:
[tex]g(x) = \frac{4x+9}{x^6+1}[/tex]
Limit as x goes to infinity:
To find the limit of a function as x goes to infinity, we consider the term with the highest exponent in the numerator and in the denominator. So
[tex]\lim_{x \rightarrow \infty} g(x) = \lim_{x \rightarrow \infty} \frac{4x+9}{x^6+1} = \lim_{x \rightarrow \infty} \frac{4x}{x^6} = \lim_{x \rightarrow \infty} \frac{4}{x^5} = \frac{4}{\infty^5} = 0[/tex]
The graphic of the function, given at the end of this answer, corroborates the answer.
Thus, the correct option is:
As x approaches plus-or-minus infinity = limit of StartFraction 4 Over x Superscript 5 EndFraction as x approaches plus-or-minus infinity, so as x approaches infinity, g (x) approaches 0.

8 <2(a + 3) < 10
Please need help at this
Answer:
1 < a < 2
Step-by-step explanation:
8 < 2 (a+3) <10
8 < 2a+6 < 10 (Simplify all parts of the inequality)
8+ −6 < 2a +6+ −6 < 10+ −6 (Add -6 to all parts)
2 < 2a < 4
2/2 < 2a/2 < 4/2 (Divide all parts by 2)
=1 < a < 2

Answer:
$2,617.50
Step-by-step explanation:
Using this table, the tax is ...
tax = 2% × $3000 + 3% × (5000 -3000) + 5% × (17000 -5000) + ...
5.75% × (50,000 -17,000)
= $60 + 60 + 600 + 1897.50
tax = $2,617.50
__
Additional comment
Above $17,000, the tax is more easily computed as ...
tax = (5.75% × income) - 257.50
Each tax bracket can have a simplified formula like this.
Last year there was a pandemic caused by xyz virus in the city of Abc. The population of the city is 15 million. The health authorities of the city are estimating that more than 3% of the people of this city were infected by this virus. In order to test this statement, they collected a sample of 1000 individuals of this city and conducted an antibody test on them. The results of the analysis showed that 40 individuals out of those 1000 people got infected during the pandemic. Is there evidence to support that more than 3% of the population of the city got infected by the virus? Use hypothesis testing.
Answer:
There is significant evidence to support that more than 3% of the population of the city got infected by the virus.
Step-by-step explanation:
x = 40 ; n = 1000
phat = x / n = 40 / 1000 = 0.04 = 4%
H0 : p = 0.3
H1 : p > 0.3
The test statistic :
(Phat - P) ÷ √(p(1 - p) / n)
1 - p = 1 - 0.3 = 0.7
(0.4 - 0.3) ÷ √(0.3(0.7) / 1000)
0.1 ÷ 0.0144913
= 6.9
Pvalue ; Using the Pvalue from Zstatistic calculator :
Pvalue < 0.00001
Reject H0, if Pvalue < α
0.00001 < α ; We reject H0 ; Hence, there is significant evidence to support that more than 3% of the population of the city got infected by the virus.

You have just finished investigating a disease outbreak at a summer picnic party. Out of 100 total attendees, a total of 50 individuals became ill. Of these, 48 individuals developed vomiting and nausea 4 to 6 hours after the picnic. No one developed a fever. Two elderly individuals, however, had complications leading to more severe form of the illness and had to be hospitalized. After the lab tests were conducted, the infectious agent was identified. The lab tests also revealed that 75% of all the individuals attending the party had been infected
What is the pathogencity of the infectious agent?
a. (2/50) * 100
b. (2/75) * 100
c. (50/75) * 100
d. (75/100) * 100
e. None of the above
Answer:
d. (75 / 100) * 100
Step-by-step explanation:
Pathogen is best described as cross contaminant which a bacteria or a virus that causes infection or disease in human. The lab tests confirms that total percentage of attendees who are infected by the disease is 75%. The total attendees were 100 out of which 75 had been infected and 50 demonstrated symptoms of the illness.

To solve y and x, I am adding a picture
Answer:
[tex]x =\sqrt 5[/tex]
[tex]y = \sqrt{5[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Solve for x
Considering angle 45 degrees, we have:
[tex]\cos(45) = \frac{y}{\sqrt{10}}[/tex] --- cosine formula i.e. adj/hyp
Solve for y
[tex]y = \sqrt{10} * \cos(45)[/tex]
In radical form, we have:
[tex]y = \sqrt{10} * \frac{1}{\sqrt 2}[/tex]
[tex]y = \sqrt{10/2}[/tex]
[tex]y = \sqrt{5[/tex]
To solve for x, we make use of Pythagoras theorem
[tex]x^2 + y^2 = (\sqrt{10})^2[/tex]
[tex]x^2 + y^2 =10[/tex]
Substitute for y
[tex]x^2 + (\sqrt 5)^2 =10[/tex]
[tex]x^2 + 5 =10[/tex]
Collect like terms
[tex]x^2 =10-5[/tex]
[tex]x^2= 5[/tex]
Solve for x
[tex]x =\sqrt 5[/tex]
What is the difference quotient of the function, g(a) = StartFraction 8 minus a Over 4 EndFraction?
PLEASE HELP
Given:
The function is:
[tex]g(a)=\dfrac{8-a}{4}[/tex]
To find:
The difference quotient of the function.
Solution:
Formula for difference quotient of the function f(x) is:
[tex]DQ=\dfrac{f(x+h)-f(x)}{h}[/tex]
We have,
[tex]g(a)=\dfrac{8-a}{4}[/tex]
The difference quotient of the function g(a) is:
[tex]DQ=\dfrac{g(a+h)-g(a)}{h}[/tex]
[tex]DQ=\dfrac{\dfrac{8-(a+h)}{4}-\dfrac{8-a}{4}}{h}[/tex]
[tex]DQ=\dfrac{\dfrac{8-a-h-8+a}{4}}{h}[/tex]
[tex]DQ=\dfrac{-h}{4h}[/tex]
[tex]DQ=-\dfrac{1}{4}[/tex]
Therefore, the difference quotient of the given function is [tex]-\dfrac{1}{4}[/tex].

The area of a square floor on a scale drawing is 25 square centimeters, and the scale drawing is 1 centimeter:5 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?
Answer:
[tex]625ft^{2}[/tex]
Step-by-step explanation:
First get the l by finding the square root of the area
[tex]\sqrt{25}[/tex] = 5cm
since 1cm = 5ft
what about 5cm =?
(5cm×5ft)/1cm
l=25ft
area of the actual floor is l × l
[tex]25^{2}[/tex]
which is [tex]625ft^{2}[/tex]
