both of them give their Rs.100 so now it's Rs.200 so pay RS 200 and they'll get Rs 50 as the remain
The number of ways of spending Rs. 150 will be 3.
What are permutation and combination?Combination and permutation are two different ways of grouping elements of a set into subsets in mathematics. The elements of the subset can be listed in any order in a combination. The elements of the subset are listed in a specific order in a permutation.
Given that Raman and Raj go to a party each having Rs. 100, If they decide to expend Rs. 150.
The number of the spending will be calculated as,
Raman + Raj = 150
100 + 50 = 150
50 + 100 = 150
75 + 75 = 150
The number of ways will be three.

assume that 2000 births are randomly selected and 64 of the births are girls. use subjective judgment to describe the number of girls as significantly high, significantly low, or neither significantly low nor significantly high. choose the correct answer below
Total no. of births = 2000
Births of girls = 64
Birth% of girls
[tex] = \frac{64}{2000} \times 100[/tex]
[tex] = \frac{64}{20} [/tex]
[tex] = \frac{6.4}{2} [/tex]
[tex] = 3.2\%[/tex]
Hence, the number of girls are significantly low.

What are the measures of angles B and C?
Figure ABCD is a parallelogram.
A.B = 15°; C = 165°
B.B = 65°; C = 115°
C.B = 65°; 2C = 65°
D.B = 15°; C = 15°
For the given parallelogram, the measure of angle B is 65° and the measure of angle D is 65°. The answer is the third option.
QuadrilateralsThere are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, for a parallelogram, its the opposite sides are equal and parallel. For a parallelogram is noted too that the opposite angles are equal.
The question gives the values of the angle B and D in function of n.
Therefore, considering that the opposite angles of the parallelogram (ABCD) are equal, so D=B. Thus,
6n-25=3n+20
6n-3n=20+25
3n=45
n=15°
Replacing the value of n in each angle (B and D). Then,
D=6n-25= 6*15-25= 90-25= 65°
B=3n+20= 3*15+20= 45+20 = 65°

Determine if the product CA is defined. If the product is defined, state its dimensions. Do not calculate the product.
Answer:
The product can be calculated.
The resulting matrix will have 3 rows and 3 columns.
Step-by-step explanation:
Matrix multiplication
To find the product of two matrices is only possible when the number of columns of the first matrix is equal to the number of rows of the second matrix.
If X is the first matrix with dimensions (n x m) and Y is the second matrix with dimensions (m x p), the product XY is possible and the dimensions of the resulting matrix are (n x p).
Matrix A has two rows and three columns (2x3)
Matric C has three rows and two columns (3x2)
If we wanted to calculate the product CA, the number of columns of C must be equal to the number of rows of A.
Since both numbers are 2, the product can be calculated.
The resulting matrix will have 3 rows and 3 columns.

9514 1404 393
Answer:
x = 10width = 10length = 45Step-by-step explanation:
The remaining work is to identify the values of x that make the factors zero:
4x +45 = 0
x = -45/4 . . . . negative dimensions are not useful
x -10 = 0
x = 10
The width is x, so the width is 10.
The length is 4x+5, so the length is 4·10+5 = 45.
The rectangle has a width, x, of 10 and a length of 45.
