Answer:
a = 1 1/15
Step-by-step explanation:
1/4 a = 4/15
Multiply each side by 4 to isolate a
4 * 1/4a = 4 * 4/15
a = 16/15
a = 1 1/15
Answer:
1 solution
Step-by-step explanation:
The solution is the intersection point, which is at (3, -2)
Let the cost price of article be x :
x + x × ( 15/100 ) = 2300
x + x × ( 5 × 3 / 5 × 20 ) = 2300
x + x × ( 3 / 20 ) = 2300
x + ( 3 × x / 20 ) = 2300
x + ( 3x / 20 ) = 2300
( 20x / 20 ) + ( 3x / 20 ) = 2300
20x + 3x / 20 = 2300
23x / 20 = 2300
Multiply both sides by 20
( 23x / 20 ) × 20 = 2300 × 20
23x = 2300 × 20
23x = 23 × 2000
Divide both sides 23
23x ÷ 23 = ( 23 × 2000 ) ÷ 23
x = Rs 2000
Answer:
Minimum = 14

Median = 32

Maximum = 65
Step-by-step explanation:
<u>Step 1: </u>Put your numbers in ascending order (from smallest to largest). For this particular data set, the order is
14, 18, 28, 29, 32, 44, 48, 50, 65
<u>Step 2:</u> Find the minimum and maximum for your data set. Now that your numbers are in order, this should be easy to spot.
Minimum = 14
Maximum = 65
<u>Step 3: </u>Find the median. The median is the middle number. The middle number in your list is 32, so
Median = 32
<u>Step 4: </u>Place parentheses around the numbers above and below the median.
(14, 18, 28, 29), 32, (44, 48, 50, 65)
<u>Step 5: </u>Find Q1 and Q3. Q1 can be thought of as a median in the lower half of the data, and Q3 can be thought of as a median for the upper half of data.
First quartile

Third quartile

<u>Step 6:</u> Write down your summary found in the above steps.
Minimum = 14

Median = 32

Maximum = 65
Hey there!
Let's work this problem out together.
Our ratio is 35:1000, or 35/1000.
Let's try solving this in two ways.
First, we can look at our ratio 35/1000, which is equal to 0.035.
35 is 0.035 of 1000.
Therefore, to find the amount of babies, we can multiply this connecting number by the number of people.
1,800,000(0.035)=63,000
Therefore, there would be 63,000 babies.
---------------------------------------------------------------
We can also solve this as a proportion.

To solve, we can cross multiply and solve for b.
1,000b=63,000,000
We divide both sides by 1,000/
b=63,000
Therefore, there are 63,000 babies.
I hope this helps!
