Answer:
The value of the 3 is 30,000,000.
Step-by-step explanation:
From the digit at the right, you go multiplying each element by 10 powered to a counter that starts at zero and increases at every digit. So:
Our counter is i
i = 0;
v(7) is the value of the 7
i = 1;
v(5) is the value of the 5
i = 2;
v(1) is the value of the 1
i = 3;
v(5) is the value of the 5
i = 4;
v(9) is the value of the 9
i = 5;
v(6) is the value of the 6
i = 6;
v(8) is the value of the 8
i = 7;
v(3) is the value of the 3
The value of the 3 is 30,000,000.
Answer:
h=48
Step-by-step explanation:
You should create an even proportion. So you could do seconds over heartbeats or the other way around. I decided to do the other way around. Since yu want to see h in m minutes and in a minute there are 60 seconds, I did 8/10 = h/60. Instead of cross multiplying, I saw that 10 times 6 is 60 so 8 x 6=h. 8 x 6 = 48 so h=48.
Normalcdf(78, 82, 80, 8/√(64)) = 0.9544997361
The standard deviation of the sample mean will be 8/√64 = 1, so you are asking for the probability that the value will be within 2 standard deviations of the mean. This is a number most statistics students are asked to memorize.
Your probability is about 0.9545.
Hi! So when you are dividing or multiplying a decimal by 10, it becomes a lot easier than it looks. If you divide by 10, you move the decimal to the left one space. If you multiply the decimal by 10, you move the decimal to the right one space. Because you are diving 12.5 by 10, you move the decimal to the left one space, which then becomes 1.25. So, Lauren has run 1.25 miles. If you want to double check, you can multiply 1.25 by 10, which comes out to 12.5. Your answer is 1.25! Hope this helps!!
