Step-by-step explanation:
Count the number of times you have to move the decimal point to the right until it is to the right of the 1st nonzero number.
a) You have to move the decimal point 11 times until it gets to the right of the 1st nonzero number, which is 7. You then rewrite this number as
The exponent of 10 is a negative number because you moved the decimal point to the right.
b) Similarly, you have to move the point 9 times to the right so the answer is
Answer: 21/4 or 5 1/4
Step-by-step explanation: sorry for the 21/4 if this is wroNG IM SOOO SORRy if it is..
using pythagorean theorem
a^2 + b^2 = c^2
(12x)^2 + (16x)^2 = 10^2
square each term
144x^2 + 256x^2 = 100
combine like terms
400 x^2 = 100
divide by 400 on each side
x^2 = 1/4
take the square root on each side
x = 1/2
Answer: x=1/2
Answer:
b. quantitative, continuous
Step-by-step explanation:
Since here Dog = 0.07
Cat = 0.1
Snake = 0.12, and so on.
It is a numeric form So, it is <em>quantitative</em> data. And we can't count them(it include numbers between two natural number) so it is <em>Continuous</em> Variable.
The variable which is in numeric form is called Quantitative Variable. Example: Weight, Marks, etc.
And, the variable which we can't count is known as Qualitative Variable. Example: Smoking, Non- Smoking, etc.
Further Quantitative Variable can be divided into two parts:
- Continuous
- Discrete
The variable which we can count is known as the Discrete variable. It includes the natural numbers only. Example: Number of apples, Number of senior citizens in a particular area, etc.
The variable which we can't count is known as Continuous Variable. Example: Height, Weight, etc.
Answer:
8.9 cm to 1 dec. place.
Step-by-step explanation:
First, use Pythagoras to find the length of BD.
BD^2 = 6^2 + 7^2 = 85
BD = √85.
BM = √85 / 2.
Consider the triangle TBM, by Pythagoras:
TB^2 = BM^2 + MT^2
MT^2 = 10^2 - (√85 / 2 )^2
= 100 - 21.25
= 78.75.
MT = 8.874
