The change is -(1/2 + 3/4 + 3/8).
If you add the fractions, you get -(13/8).
Answer: 0.1334
Step-by-step explanation:
Given
There are seven trails with a probability of success is 

Using the binomial distribution, the Probability of exactly no success i.e. x=0 is given by

The number 12,300 is written 1.23 x 10⁴ as a scientific notation. It's coefficient is 1.23; base is 10⁴ in exponent form.
Scientific notation is a method developed by scientists to shorten the number that expresses a very large number. The scientific notation is based on powers of the base number 10.
Scientific notation has two numbers: coefficient and base. The coefficient must be greater than or equal to 1 and less than 10. The base is always 10 written in exponent form.
12,300 as coefficient in standard form in scientific notation.
1) put decimal after the first digit and drop the zeros. from 12,300 to 1.23 this is the coefficient.
2) to find the exponent, count the number of places from decimal to the end of the number.
1.2300 ; there are 4 places
So the scientific notation is 1.23 x 10⁴
Answer:
B
Step-by-step explanation:
Drop an altitude. Either of the two resulting right triangles with legs of length 5 and x and a hypotenuse of 10.
By the Pythagorean theorem, it follows that the answer is B.
Answer: 2730 tiles (Approx)
Step-by-step explanation:
Since, The side length of each side = 25
According to the question the shape of the tile is square.
Thus, the area of one tile = 25 × 25 = 625 
Also, we need to tile a kitchen measuring 102 ft. by 18 ft
Thus, the area of the room in which we have to tile = 102 × 18 = 1836
= 1836×30.48 × 30.48 = 1705699.8144 
Thus, the total number of the tiles = the area of the room in which we have to tile / the area of one tile =
Since, we must take 2730 tiles to tile the kitchen.
