Answer:
ADC, ADB, BCD
Step-by-step explanation:
They all have the same area as ABC.
Solution: Which statement about the scatter plot is true?
The correct answer is option A. As the number of weeks in class increases, the number of keyboarding mistakes decreases.
Explanation: From the scatter plot, we clearly see there exists a negative linear relationship between the number of weeks in class and the number of mistakes. And we know that if there exists a negative linear relationship between the two variables, then the values of two variables move in opposite direction. If the values of one variable goes up, the values of other variable go down. From the given scatter plot, we clearly see the number of mistakes goes down as the number of weeks in class increases. Therefore, the option A is correct
Answer:
Standard factor form of the integer : 15400 = 2³ × 5² × 7 × 11
Step-by-step explanation:
According to the unique factorization theorem, a given integer n (where, n>1), either is a prime number or can be represented as the product of the prime numbers.
Firstly, it is checked that the given integer is divisible by the smallest prime number 2 . If the integer is not divisible by 2, then the integer is checked for the next prime number 3 and then checked for 5 and so on until the remaining integers are prime numbers.
So, the standard factored form of the integer:
15400 = 2 × 770
15400 = 2 × 2 × 3850
15400 = 2 × 2 × 2 × 1925
15400 = 2 × 2 × 2 × 5 × 385
15400 = 2 × 2 × 2 × 5 × 5 × 77
15400 = 2 × 2 × 2 × 5 × 5 × 7 × 11
or,
15400 = 2³ × 5² × 7 × 11
Therefore, the standard factor form of the integer: 15400 = 2³ × 5² × 7 ×11
Answer:
44.040192
Step-by-step explanation:
I barely remember doing this in math. I did some research on the question and that's the answer that I got. If I'm not wrong, the formula you are supposed to use is:
y = a(r)^t
A being the regular number in the problem (210).
R is the rate/ ratio (8% which would be converted to 0.8).
T is the time (7 years).
Put the equation together, and you get y = 210(0.8)^7. When you plug it into a calculator, you get 44.040192.
Sorry for the long explanation, but I hope this helps you solve your problem!
