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.
Answers
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.

Step-by-step explanation:
the triangle area= 5x4/2= 20/2= 10
there are 4 triangles so 10 x 4=40
square area= 5x5= 25
40+25= 65units^2
Question is on the picture/screenshot
Answers
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

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.
Answers
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.
Lisa made a chocolate milkshake in the blender for her daughter. The milkshake occupies just a little more than 75 cubic inches of space in the blender pitcher. When serving the milkshake to her daughter, she has three glasses to choose from. Determine whether or not each of the three classes is large enough to contain all of the chocolate milkshake that Lisa made for her daughter. Use 3.14 to approximate .
Glass A with a height of 2.1 inches and a diameter of 5 inches is
to contain the entire chocolate milkshake.
Glass B with a height of 2.7 inches and a radius of 4.6 inches is
to contain the entire chocolate milkshake.
Glass C with a height of 3.1 inches and a radius of 2.7 inches is

Answer:
Only Glass B is large enough
Step-by-step explanation:
For repetitive calculations, I like to use a calculator or spreadsheet. The attachment shows the volumes for the three glasses. Only Glass B has a volume that exceeds 75 cubic inches.

Note that Glass A has a diameter of 5 inches, so a radius of 2.5 inches.

What is the surface area of the triangular prism shown?
Answers
9514 1404 393
Answer:
(b) 976 m³
Step-by-step explanation:
The total surface area is the sum of the areas of the faces and bases.
The two bases are triangles, each with area ...
A = 1/2bh
So, the two of them together will have an area of ...
A = 2(1/2)bh = bh
where b is the base of the triangle, and h is its height. These values are shown as 14 m and 24 m, respectively.
Total base areas = (14 m)(24 m) = 336 m²
__
The total area of the rectangular faces is the sum of products of length and width. The width of each face is the same as the height of the prism, and the sum of face lengths is the perimeter of the triangular base.
The prism height is 10 m, and the perimeter of the base triangle is (14 m +25 m +25 m) = 64 m. Then the lateral area of the prism is ...
Total lateral area = (10 m)(64 m) = 640 m²
So, the total surface area of the prism is ...
base area + lateral area = 336 m² + 640 m² = 976 m²
Find the area. Simplify your answer.

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]

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.
Answers
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.

$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.
