if i was to do this quetsion, i would add 3 and 5 as thats the total on average and i will get 8
i divide 40 by 8
i get 5
that means that i will have to multiple 3 and 5 by 5
i will get 15 and 25
since i know the 5 apples was multiplied by 5 to get 25 apples
there are 25 apples in the basket
Answer:
4
Step-by-step explanation:
i need to know the scale factor of the first image in order to figure out the scale factor for the second one
Answer:y=15
3 y
___=___
15 75
cross multiply
15y=225
divide both sides by 15
y=15
The interval given was 33% to 37%
This means that subtracting the margin of error from the percentage of the population that visit the library once a year gives the lower end and adding the margin of error to the percentage of the population that visit the library once a year gives the upper end
Let x denote margin of error and y denotes the percentages of the population that visit the library once a year
we can get the following equations and solve for the values of x and y
Adding eqn1 and eqn2 to gives
Putting the value of y into any of the equations
Thus, the margin of error is
Therefore we enter 2 in the box
Answer:
Given: ABCD is a parallelogram,
In which E ∈ BC and F lies on the extension of DC,
Such that line segment EF goes through the vertex A.
To prove:
Proof:
Since, By the definition of parallelogram,
By the Alternative interior angle theorem,
Also, ( vertically opposite angles )
Thus, By AA similarity postulate,
Hence proved.
