Answer:
Se contagiarian 160 personas.
Step-by-step explanation:
Para este problema debenos usar la siguiente regla de tres:
[tex]\frac{10(personas)}{4(enfermas)}=\frac{400(personas)}{x(enfermas)}[/tex]
Ahora, debemos despejar x de la ecuacion de arriba.
[tex]x=\frac{400(personas)*4(enfermas)}{10(personas)}[/tex]
[tex]x=160(enfermas)[/tex]
Por lo tanto, se contagiarian 160 personas.

Round to the nearest tenth.
Answer:
42.4 m²
Step-by-step explanation:
The formula for the Area of this triangle = 1/2 absinθ
a = 8m
b = 12m
θ = 62°
The area of the triangle =
1/2 × 8m × 12m × sin 62
= 42.38 m²
Approximately = 42.4 m²

Step-by-step explanation:
In a small town of 5,832 people, the mayor wants to determine the proportion of voters who would support an increase to the food tax. An assistant to the mayor decides to survey 1,000 randomly chosen people to construct a 90% confidence interval for the true proportion of people who would support the increase in food tax. Of the sample, 363 people say they would support the increase. Are the conditions for inference met?
Yes, the conditions for inference are met.
No, the 10% condition is not met.
No, the randomness condition is not met.
No, the Large Counts Condition is not met.
Answer:
No, the 10% condition is not met is the answer.
1,000/5,832 is 0.1714, or ~17%, which is more than 10% of the population.
No, the 10% condition is not met.
Ratio:
'Ratio is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another.'
Proportion:
'A proportion is an equation in which two ratios are set equal to each other.'
According to the given problem,
Total number of people in the town = 5832
Number of people to be surveyed = 1000
Ratio of number of people chosen to the total population = [tex]\frac{1000}{5832}[/tex]
= 0.17
Therefore percentage of people to be surveyed = 0.17 × 100
= 17%, which is more than 10%
Hence, we can conclude that the 10% condition is not met.

Answer:
AC = 28
Step-by-step explanation:
ΔADB ≈ ΔDBC
DC / BC = AD / 15
16 / 20 = AD / 15
cross-multiply:
20AD = 240
AD = 12
AD + DC = AC
12 + 16 = AC

I need help on this lol
Answer:
-62
Step-by-step explanation:
180-w+49(angles on a straight line=180)
angles on a triangle=180
Hence,
180-w+49+w+17+w-4=180
collect the like terms
180+49+17-4+w+w-w=180
242+w=180
Take 180 to the other side and also w
242-180=-w
62=-w same as w=-62

s^3–1=( ) (s^2+s+1). Help ASAP
Answer:
(s - 1)(s² + s + 1)
Step-by-step explanation:
s³ - 1 ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
s³ - 1
= s³ - 1³
= (s - 1)(s² + s + 1)
The required factorized form of the given expression is (s - 1)(s² + s + 1).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
We have been given that the expression below as
s³ - 1
We have to determine the factor of the given expression
As per the question, we have
s³ - 1
This is a difference between cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
⇒ s³ - 1 = s³ - 1³
⇒ (s - 1)(s² + s + 1)
Thus, the required factorized form is (s - 1)(s² + s + 1).

The population of town is 32600. about 27% are over 60 years old. About 19% are 16 or under. How many are between 16 and 60?
Answer:
Number of population between 16 and 60 =17,604
Step-by-step explanation:
population of town = 32600
Percentage of people over 60 years old=27%
Percentage of people 16 or under =19%
Percentage of people between 16 and 60= 100%-(27% +19%)
100-(46) =54%
Number of population between 16 and 60 =Percentage of people between 16 and 60 x population of town
=54% x 32600
=17,604

Answer:
6. Additional information is required on the two triangles
7. The pair of triangles are similar by SAS similarity postulate
8. Yes, by triangle proportionality theorem
9. DE = 9
Step-by-step explanation:
When two or more triangles are similar, the ratio of the corresponding sides of both triangles is constant
6. From the given figure, more information is required on the two triangles
However, whereby the side with length 10 is parallel to the corresponding side on the other triangle, then the alternate angles formed by the transversal to the two parallel lines are equal and the two triangles are similar by Angle Angle, AA, similarity postulate
7. From the given triangles, the ratio of the corresponding sides relative to the given included angles are;
18/45 and 10/25
18/45 = 2/5
10/25 = 2/5
Therefore, given that two pair of corresponding sides have the same included angle and that the two included corresponding sides of the of the two triangles are proportional, then the two triangles are similar by the Side Angle Side SAS similarity postulate
8. By triangle proportionality theorem, we have;
If [tex]\overline{MN}[/tex] ║ [tex]\overline{KL}[/tex], then we have;
3/6 = 4/8 = 2
∴ [tex]\overline{MN}[/tex] ║ [tex]\overline{KL}[/tex]
9. By triangle proportionality theorem, where [tex]\overline{BE}[/tex] ║ [tex]\overline{CD}[/tex], we have;
12/20 = DE/15
∴ DE = 15 × 12/20 = 9
DE = 9
What is the distance between the points (-5, 9) and (4, 9) on the coordinate plane? 9 9 1 1 10 10 90
Answer:
9 units
Step-by-step explanation:
Given: Two points on a coordinate plane are [tex](-5,9),\,(4,9)[/tex]
To find: distance between points [tex](-5,9),\,(4,9)[/tex]
Solution:
According to the distance formula,
Distance between points [tex](a,b)[/tex] and [tex](c,d)[/tex] is equal to [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]
Take [tex](a,b)=(-5,9),\,(c,d)=(4,9)[/tex]
Therefore,
Distance between points [tex](-5,9),\,(4,9)[/tex] [tex]=\sqrt{(4+5)^2+(9-9)^2}[/tex]
[tex]=\sqrt{(9)^2}[/tex]
[tex]=9[/tex] units
