Answer:
Nurse Sanders examines immunization records for this past winter at the school where she works How many students were vaccinated but got the flu anyway.
A.18
The correct answer is A. 14 number of students were vaccinated but got the flu anyway.
Based on the given information, we can determine the number of students who were vaccinated but got the flu by subtracting the number of students who were vaccinated and didn't get the flu from the total number of vaccinated students.
Number of students vaccinated but got the flu = Total vaccinated - Vaccinated and didn't get flu
Number of students vaccinated but got the flu = 600 - 586
Number of students vaccinated but got the flu = 14
Therefore, the correct answer is A. 14 number of students were vaccinated but got the flu anyway.

Find EF in the parallelogram
Answer:
EF = 13
Step-by-step explanation:
Opposite sides of a parallelogram are of equal lengths (properties of a parallelogram)
Therefore,
EF = DG
x + 3 = 2x - 7 (substitution)
Collect like terms
x - 2x = -3 - 7
-x = -10
Divide both sides by -1
x = -10/-1
x = 10
✔️EF = x + 3
Plug in the value of x
EF = 10 + 3
EF = 13
A helicopter is sighted at the same time by two ground observers who are 5 miles apart, both ahead of the helicopter and in its direction of travel. They report angles of elevation of 19.5° and 31.2° to the helicopter. Find the distance from the helicopter to the further observer, to the nearest tenth of a mile.
Answer:
The distance from the helicopter to the further observer is:
d = 12.77 miles
Step-by-step explanation:
The observer with 19.5° of elevation will be denoted by 1
The observer with 31.2° of elevation will be denoted by 2.
Here we have two right triangles. Both of them have the same opposite sides, so will be useful to use the tangent function.
For the second observer:
[tex]tan(31.2)=\frac{h}{x}[/tex] (1)
Where:
h is the opposite sidex is the adjacent side (distance from the observer 2 to the point where the angle of elevation is 90° )For the first observer:
[tex]tan(19.5)=\frac{h}{5+x}[/tex] (2)
Where:
h is the opposite side5+x is the adjacent side (distance from the observer 1 to the 90° elevation point, 5 miles is the distance between observes )Let's find x from equations (1) and (2). Both of them have the variable "h" so we can equal these equations.
[tex]xtan(31.2)=(5+x)tan(19.5)[/tex]
[tex]x(tan(31.2)-tan(19.5))=5tan(19.5)[/tex]
[tex]x=\frac{5tan(19.5)}{tan(31.2)-tan(19.5)}[/tex]
[tex]x=7.04\: miles[/tex]
Now, if we use the right triangle with 19.5° of elevation, the hypotenuse will be the distance from the helicopter and the further observer (let's call d).
Let's use the cosine function to find d.
[tex]cos(19.5^{\cric})=\frac{5+x}{d}[/tex]
[tex]d=\frac{5+7.04}{cos(19.5^{\cric})}[/tex]
[tex]d=12.77\: miles[/tex]

△AOC~△BOD. Identify the coordinates of D and the scale factor.
A.) D (0, −7 1/12); 2/5
B.) D (0, −1 1/5); 5/2
C.) D (0, −7 1/2); 5/2
D.) D (0, −1 1/5); 2/5
The coordinate of D is [tex](0, -1\frac{1}{5})[/tex] and the scale factor is 2/5.
The correct option is D.) D (0, −1 1/5); 2/5
To determine the coordinates of D, we will first determine the length of /OD/
Consider △AOC and △BOD. They are similar triangles.
From the diagram, we can determine the lengths of the sides of each triangle /OB/ = 2 units, /OA/ = 5 units, /OC/ = 3 units and /OD/ is unknown
Since △AOC is similar △BOD, then we can write that
[tex]\frac{/OB/}{/OA/} = \frac{/OD/}{/OC/}[/tex]
∴ [tex]\frac{2}{5} = \frac{/OD/}{3}[/tex]
[tex]/OD/ \times 5 = 2 \times 3[/tex]
[tex]/OD/ \times 5 = 6[/tex]
Then,
[tex]/OD/ = \frac{6}{5}[/tex]
∴ [tex]/OD/ = 1\frac{1}{5}[/tex]
Hence, the coordinate of D is [tex](0, -1\frac{1}{5})[/tex] since D is on the negative side of the y-axis.
For the scale factor,
Scale factor = [tex]\frac{/OB/}{/OA/}[/tex]
Scale factor = [tex]\frac{2}{5}\\[/tex]
Hence, the scale factor is 2/5
The correct option is D.) D (0, −1 1/5); 2/5

Determine if events A and B are mutually exclusive.
P(A) = 1/4 P(B) = 3/5 P(A or B) = 7/10
A) Not mutually exclusive
B) Mutually exclusive
Answer:
A) Not mutually exclusive
Step-by-step explanation:
Given
[tex]P(A) = \frac{1}{4}[/tex]
[tex]P(B) = \frac{3}{5}[/tex]
[tex]P(A\ or\ B) = \frac{7}{10}[/tex]
Required
Determine if they are mutually exclusive or not
Mutually exclusive are defined by:
[tex]P(A\ or\ B) = P(A) + P(B)[/tex]
So, we have:
[tex]P(A\ or\ B) = \frac{1}{4} + \frac{3}{5}[/tex]
Take LCM
[tex]P(A\ or\ B) = \frac{5+12}{20}[/tex]
[tex]P(A\ or\ B) = \frac{17}{20}[/tex]
By comparing:
[tex]P(A\ or\ B) = \frac{17}{20}[/tex] ---- Calculated
[tex]P(A\ or\ B) = \frac{7}{10}[/tex] ---- Given
We can conclude that A and B are not mutually exclusive because:
[tex]\frac{17}{20} \ne \frac{7}{10}[/tex]
