To convert the value 30 in decimal notation to an 8-bit binary integer, you may use any one of the following representation methods: a) the complement of one's opposite; b) the opposite of excess; or?

1) Find the equivalent decimal value of the following floating-point representation using IEEE 754 standard single-precision (32-bit floating-point number with bias = 127)  1 0111 1111 1110 0000 0000 0000 0000 000 (The quiz is expecting a decimal numeric entry. It will automatically suppress leading and trailing zeros. It will display your answer with commas every third digit.)   2) Find an IEEE 754 floating-point representation of -74.2 decimal number. Enter 32 bits without a space.  (The quiz is expecting a fill in the blank text string in the entry box and grades on an exact match with the expected result. The answer should be formatted as a 32-bit IEEE 745 binary number representation)
