Answer:
The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.
Step-by-step explanation:
Given the survey, the prevalence of the flu, as a percentage, is given by:
Number of individuals diagnosed with flu, multiplied by 100, and divided by the size of the sample.
In this question, we have that:
Sample of 25,000, and 4,250 of those had been diagnosed with the flu at some point in the past year. So, the prevalence of the flu is given by:
[tex]\frac{4250*100}{25000} = 17[/tex]
The prevalence of flu for the past year, as indicated from the survey participants, was of 17%.

You flip a fair coin 8 times in a row. What is the probability that it will land on tails every single time? Write the answer as a fraction.
Answer:
50/100 chance
Step-by-step explanation:
It would be a 50/50 chance, because the coin has two sides, so it's a 50/50 chance that it'll land on tails all 8 times.

Inverse Trigonometry solve the questions below
Answer:
1. θ = 34.85°
2. x = 36.31°
3. x = 39.80°
Step-by-step explanation:
1. Determination of θ.
Adjacent = 11.9
Hypothenus = 14.5
Angle θ =?
Cos θ = Adjacent /Hypothenus
Cos θ = 11.9 / 14.5
Cos θ = 0.8207
Take the inverse of Cos
θ = Cos¯¹ 0.8207
θ = 34.85°
2. Determination of x
Opposite = 9 m
Hypothenus = 15.2 m
Angle x =?
Sine x = Opposite /Hypothenus
Sine x = 9 / 15.2
Sine x = 0.5921
Take the inverse of Sine
x = Sine¯¹ 0.5921
x = 36.31°
3. Determination of x
Opposite = 10 in
Adjacent = 12 in
Angle x =?
Tan x = Opposite / Adjacent
Tan x = 10 / 12
Tan x = 0.8333
Take the inverse of Tan
x = Tan¯¹ 0.8333
x = 39.80°

what is the gcm of -4 and 6?
Answer:
Step-by-step explanation:
We will first find the prime factorization of 4 and 6. After we will calculate the factors of 4 and 6 and find the biggest common factor number .
Step-1: Prime Factorization of 4
Prime factors of 4 are 2. Prime factorization of 4 in exponential form is:
4 = 22
Step-2: Prime Factorization of 6
Prime factors of 6 are 2, 3. Prime factorization of 6 in exponential form is:
6 = 21 × 31
Step-3: Factors of 4
List of positive integer factors of 4 that divides 4 without a remainder.
1, 2
Step-4: Factors of 6
List of positive integer factors of 6 that divides 4 without a remainder.
1, 2, 3
Final Step: Biggest Common Factor Number
We found the factors and prime factorization of 4 and 6. The biggest common factor number is the GCF number.
So the greatest common factor 4 and 6 is 2.
Answer: 2 the gcm of -4 and 6 is two

Help me to solve chart
Answer:
Here,
the given expression is:
3x-15
when x=1
then
=3×1-15
=3-15
=-12
when x=2
then
=3×2-15
=6-15
=9
when x=3
then
=3×3-15
=9-15
=6
the value of x in expression 3x-15 is -12,9 and 6.
Answer:
1 = (3 x 1) - 15
2= (3 x 2)- 15
3= (3 x 3)- 15
Step-by-step explanation:
1= -12
2= 9
3= 6

A recipe calls for 2/3 cup of sugar per batch. Elena used 5 1/3 cups of sugar to make several batches of cookies. How many batches of cookies did she make?
Answer:
8 batches
Step-by-step explanation:
To get the number of batches she made, we can just use proportion to solve it. But first, we need to convert 5 1/3 to improper fraction
5 1/3 = 16/3Then we can now use the proportion to solve
2/3 cups = 1 batch
16/3 cups = x (note:5 1/3=16/3)
cross multiply
2/3 × x = 16 /3
2x/ 3 = 16/3
we need to make x the subject of the formula, to do that we will multiply each side of the equation by 3/2
2/3 × 3/2 x = 16/3 × 3/2
6x /6 = 48 / 6
x = 8
Therefore she made 8 batches of cookies.
Which is the smallest?
(a) -1,
(b) -1/2,
(c) 0,
(d) 3.
Answer:
i think the answer is -1/2 tho hopefully it is
Answer:
The smallest is -1
Step-by-step explanation:
-1 is the smallest because all the others are greater.
Lets say -1 and -3
-3 is the smallest because when you have negatives the number closer to zero in the negative side will always be bigger than a negative number farther from zero.
