Percentage of flu vaccine has been given 94.33%
What is percentage?
Percentage is defined as ratio expressed as a fraction of 100.
The physician have total 1500 flu injections
300 shots given in September,
450 shots given in October,
and 665 shots given in November,
Total flu vaccine has been given = 300+450+665 = 1415
Percentage of flu vaccine has been given = (1415/1500)×100%
Percentage of flu vaccine has been given = 0.9433×100%
Percentage of flu vaccine has been given = 94.33%
Hence, percentage of flu vaccine has been given 94.33%

This figure shows how to create a six-pointed star from twelve equilateral triangle tiles: [asy]

path p=c-cis(1,i)--c-cis(1,i+120)--c-cis(1,i-120)--cycle;
fill(p,orange+white);
draw(p);
pair c=cis(2.4,i);
path p=c+cis(1,i)--c+cis(1,i+120)--c+cis(1,i-120)--cycle;
fill(p,orange+white);
draw(p);
};
label("$\longrightarrow$",(4,0));
pair x=(8,0);
real s=sqrt(3);
path p=x+cis(s,0)--x+cis(3,30)--x+cis(s,60)--x+cis(3,90)--x+cis(s,120)--x+cis(3,150)--x+cis(s,180)--x+cis(3,210)--x+cis(s,240)--x+cis(3,270)--x+cis(s,300)--x+cis(3,330)--cycle;
fill(p,orange+white);
draw(p);
[/asy] If each of the original tiles has a perimeter of $10$ cm, what is the perimeter of the final star in cm?
Answer:
40 cm
Step-by-step explanation:
Each point of the final 6-pointed star has 2/3 of the perimeter of the equilateral triangle. So, the 6 points have a total perimeter of ...
6(2/3)(10 cm) = 40 cm
The perimeter of the final star is 40 cm.
Answer:
40
Step-by-step explanation:
The star has $12$ sides. Each side is one-third of the perimeter of a triangular tile, or $\frac{10}3$ cm. So the perimeter of the star is
$$12\cdot\frac {10}3 = 4\cdot 10 = \boxed{40\text{ cm}}.$$
Alternatively, consider that the original tiles are composed of $12$ triangles with $3$ sides each, which have $12\cdot 3 = 36$ sides in all. Only $12$ of those $36$ sides make up the perimeter of the star. $12$ is one-third of $36,$ so the perimeter of the star is one-third of the total perimeter of the tiles. The tiles have a total perimeter of $10 \cdot 12=120\text{ cm},$ so the perimeter of the star is $\frac{120}3 = 40$ cm.

Barry has been watching the geese that live in his neighborhood. The number of geese changes each week. n f(n) 1 56 2 28 3 14 4 7 Which function best shows the relationship between n and f(n)? f(n) = 28(0.5)n f(n) = 56(0.5)n−1 f(n) = 56(0.5)n f(n) = 112(0.5)n−1
Answer:
B. f(n) = 56(0.5)^n-1
Step-by-step explanation:
First, You have to find out the starting population, if you look at the problem you see the population starts at 56
f(x) = 56
Second, you know that the population goes down 50% each week so it has a decay of 0.5
f(x) = 56(0.5)
Third, you need to add the exponent of n to make it exponential. But, if you just add n then the the population would be 28 on week 1 which is incorrect. To fix that you make the exponent n-1 so when you are on week 1 it doesn't become 28 but it stays on 56, and on week 2 it's 28, ect
f(x) = 56(0.5)^n-1

tiled floor
Entar
Answer:
321/8 ft^2
Step-by-step explanation:
The whole area is 49/4 × 5 = 245/4 ft^2
The area of tiled floor is 13/2 × 13/4 = 169/8
245/4 - 169/8 we need to equalise the bottom of fraction to subtract so
2/2 × 245/4 = 490/8
490/8 - 169/8 = 321/8 ft^2
Using a table of values, determine the solution to the equation below to the nearest fourth of a unit. 2^x=1-3^x
Answer:
Option (1)
Step-by-step explanation:
Given equation is,
[tex]2^x=1-3^x[/tex]
To determine the solution of the equation we will substitute the values of 'x' given in the options,
Option (1)
For x = -0.75
[tex]2^{-0.75}=1-3^{-0.75}[/tex]
0.59 = 1 - 0.44
0.59 = 0.56
Since, values on both the sides are approximately same.
Therefore, x = -0.75 will be the answer.
Option (2)
For x = -1.25
[tex]2^{-1.25}=1-3^{-1.25}[/tex]
0.42 = 1 - 0.25
0.42 = 0.75
Which is not true.
Therefore, x = -1.25 is not the answer.
Option (3)
For x = 0.75
[tex]2^{0.75}=1-3^{0.75}[/tex]
1.68 = 1 - 2.28
1.68 = -1.28
Which is not true.
Therefore, x = 0.75 is not the answer.
Option (4)
For x = 1.25
[tex]2^{1.25}=1-3^{1.25}[/tex]
2.38 = 1 - 3.95
2.38 = -2.95
It's not true.
Therefore, x = 1.25 is not the answer.
The graph of a quadratic function intercepts the x-axis in two places and the y-axis in one place. According to the fundamental theorem of algebra, which of the following statements is correct? A. The quadratic function has no real zeros and two complex zeros. B. The quadratic function has one distinct real zero and one distinct complex zero. C. The quadratic function has two distinct real zeros and one distinct complex zero. D. The quadratic function has two distinct real zeros.
Answer: D. The quadratic function has two distinct real zeros.
There are no complex roots as a quadratic's roots are maxed out at 2. The fundamental theorem of algebra says that if you have an nth degree polynomial, then the max number of real roots is n.
This quadratic's roots are distinct because the two x intercepts are in different places. Each x intercept is a root.

Points A, B, and C are collinear. Point B is between A and C. Find the length indicated. Find BC if AB=2x-12, AC=14, and BC=x+2
Answer: BC = 10
======================================================
Work Shown:
The term "collinear" means all points fall on the same straight line.
Point B is on segment AC.
Through the segment addition postulate, we can say
AB+BC = AC
This is the idea where we glue together smaller segments to form a larger segment, and we keep everything to be a straight line.
Apply substitution and solve for x
AB+BC = AC
2x-12+x+2 = 14
3x-10 = 14
3x = 14+10
3x = 24
x = 24/3
x = 8
Then we can find the length of BC
BC = x+2
BC = 8+2
BC = 10
--------
Note that AB = 2x-12 = 2*8-12 = 16-12 = 4
and how AB+BC = 4+10 = 14 which matches with AC = 14
Therefore we have shown AB+BC = AC is true to confirm the answer.
Collinear points are points on the same line.
The value of BC is 10
Since points A, B and C are on the same line, where B is between points A and C.
So, we have:
[tex]AC = AB + BC[/tex]
Substitute values for AC, AB and BC
[tex]14 = 2x - 12 + x + 2[/tex]
Collect like terms
[tex]2x +x =14 + 12 - 2[/tex]
[tex]3x =24[/tex]
Divide both sides of the equation by 3
[tex]x =8[/tex]
Substitute 8 for x in BC = x + 2
[tex]BC =8 + 2[/tex]
[tex]BC =10[/tex]
Hence, the value of BC is 10

a jar had 6 red marbles and 4 blue marbles. you randomly choose two marbles. find the probability that both marbles are red.
Hey there! I'm happy to help!
If we have 6 red marbles and 4 blue marbles, we have 10 total marbles.
First, we have the probability that a marble we draw is red, which is 6/10. This simplifies to 3/5.
If this happens, there are only 5 red marbles left and 9 total ones. So, the probability of drawing a red one again is 5/9.
We multiply these two probabilities together to see the probability of them both happening.
[tex]\frac{3}{5} *\frac {5}{9}= \frac{1}{3}[/tex]
The probability that both marbles are red is 1/3.

Answer:
4 cm
Step-by-step explanation:
Volume is given by area of cross section * height
_______________________________
For condition 1
height = 12 cm
base for area of cross section is 5*8
that is length 8 cm and width 5 cm
thus area of cross section = 5*8 = 40 cm square
volume of milk = area of cross section* height of milk = 40*12 = 480 cm cube.
_______________________________________________
now milk is turned such that base of area of cross section will
15 by 8
that is length: 15 cm and width : 8 cm
thus area of cross section = 15*8 = 120 cm square
let the depth of milk be x
thus, volume of milk = area of cross section* height of milk = 120*x
= 120x cm cube
Since milk is in the same container , its volume before and after the change of alignment of container will remain same
thus
120x cm cube = 480 cm
=> x = 480/120 = 4
Thus, depth under given situation will be 4 cm.
