2x + 3y = 630
x + y = 245 then you want to get rid of x so in the second equation × by -2 and get -2x -2y =-490 subtract this equation from the first to get y=$140 substitute 140 in for y and get x= $105 and 2x=210 and 3y=420 210 +420=630
Answer:
1/13 chance or roughly 7.7% chance.
Step-by-step explanation:
There are 4 Kings in a standard 52-card deck. If one King was to be pulled out, you'd get a probability of 4/52 chance of pulling a king. Simplified, 4/52 is 1/13 chance.
Solution:
A function is always a relation but a relation is not always a fucntion.
For example
we can make a realtion of student roll number and their marks obtained in mathematics.
So we can have pairs like (a,b), (c,d)..etc.
Its a realtion but it may not be function. Because function follows that for same input there should not be diffrent output, aslo there could be many inputs to one output in the case of constant function . But this doesn't holds a necessary condition in case of relation.
Because two diffrent students with two diffrent Roll number may have same marks.
Hence the foolowing options holds True in case of a function.
A) many inputs to many outputs or one input to one output.
D) one input to one output or many inputs to one output.
Answer:
True
Step-by-step explanation:
an obtuse triangle is a big one, an acute triangle is a small one. They are both triangles, but they are not similar besides that
Answer:
Urban area = 58.27%
Suburban area = 34.83%
Rural area = 6.9%
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Total number of women = 290
Number of women in urban area = 169
Suburban area women = 101
Rural are women = 20
So, we can calculate the percentage of number of women from each area by using following formula,
Percentage = Women in specific area ÷ total women
So, percentage of Urban area = 169 ÷ 290 = 0.5827 or 58.27%
percentage of suburban area = 101 ÷ 290 = 0.3483 or 34.83%
percentage of rural area = 20 ÷ 290 = 0.0690 or 6.9%
Pie chart for the given information is attached below.
