Visitors to a cinema are either children, adults or pensioners the ratio of children to adult visitors is 1 : 2 the ratio of adults to pensioners is 3 : 4 a stratified sample is to be taken from the cinema visitors how many pensioners should be in the sample?
Answers
Answer:
the number of pensioners in the sample is 40
Step-by-step explanation:
The computation of the number of pensioners in the sample is shown below:
Given that
The Ratio of children to adult visitors is 1:2
The ratio of adults to pensioners is 3:4
And, the total number of seats is 85
Based on the above information,
The common ratios we could write as
1.5 : 3 : 4
Now we doubled it
3 : 6 : 8
So, the number of pensioners in the sample is
= 85 × 8 ÷ (3 + 6 +8)
= 40
Hence, the number of pensioners in the sample is 40

A rectangle has the are of 60 inch2. What can be its dimensions? Copy and fill in the chart.
Answers
Answer:
In order of the blanks from left to right, 30; 6; 2; 1/2; 20; 12; 12; 3/5
Step-by-step explanation:
So the rectangle has an area of 60 inches squared & the equation for the area of a rectangle is width * height. So, you can find the missing term if you just take 60 & divide it by the given number.
60/2 = 30
60/10 = 6
60/30 = 2
60/120 = 1/2
60/3 = 20
60/5 = 12
60/5 = 12
60/100 = 3/5

y=6x+30
Step-by-step explanation:
y is the total temperature
6x is the increase of temperature by 6° per x hours
30 is the y-intercept, you start with this number
9514 1404 393
Answer:
y = 30 + 6xsee below for a graphStep-by-step explanation:
The increase in temperature is the product of the increase per hour and the number of hours: 6x.
The temperature at any time is the sum of the initial temperature (30°) and the increase (6x).
y = 30 + 6x . . . . . temperature equation

This is graphed as a line with an initial value of 30 and a slope of 6. (Note the attached graph has different grid line spacing vertically than horizontally.)

Answer:
x = 36
Step-by-step explanation:
The sum of all the angles in a triangle is 180
Add the known angles together
54 + 90 = 144
then subtract 180 and 144 to find x
180 - 144 =36
The ratio of boys to girls in the ninth grade is 6:5. If there are 185 girls in the class, how many boys are there?
Answers
Answer:
[tex]222[/tex] boys
Step-by-step explanation:
Let [tex]x[/tex] = total number of ninth graders. By knowing how many students there are in the grade, we can find for the number of boys.
[tex]\frac{5}{6+5}x = 185[/tex] (number of girls in ninth grade)
[tex]\frac{5}{11}x = 185[/tex]
[tex]x=407[/tex]
To find for the number of boys, we can use substitution:
[tex]\frac{6}{6+5}x = \frac{6}{11}(407)[/tex]
[tex]=222[/tex]
∴ There are [tex]222[/tex] boys in the class.

how do I get the answer for this quadratic equation in simplest form?
[tex]4( x - 7)^2 - 48 = 12[/tex]
Answers
Answer:
x = 7 ± [tex]\sqrt{15}[/tex]
Step-by-step explanation:
Given
4(x - 7)² - 48 = 12 ( add 48 to both sides )
4(x - 7)² = 60 ( divide both sides by 4 )
(x - 7)² = 15 ( take the square root of both sides )
x - 7 = ± [tex]\sqrt{15}[/tex] ( add 7 to both sides )
x = 7 ± [tex]\sqrt{15}[/tex]
