SO do the one in the paranthesis first.

First we need to add the paranthesis. Which we will get 3.

3*2 ( because multiply goes first). Then divide the number 6 with the conclusion of 1. Then as we add and subtract 1, we will get the answer 1!

Answer : 1!

What is the 1oth term of this sequence <br> 0.75,1.5,3,6,12

aleksandr82 [10.1K]

Seems to be a geometric sequence which is found by
$a_{n}=a_{1}(r)^{n-1}$

an=nth term
a1=first term
r=common ratio

first term is 0.75
it doubles each time so common ratio is 2

$a_{n}=0.75(2)^{n-1}$
to find the nth term, input n and evaluate
example
to find the 20th term
$a_{50}=0.75(2)^{20-1}$
$a_{50}=0.75(2)^{19}$
$a_{50}=0.75(1048576)$
$a_{50}=786432$

just to find the kth term, input k for n in
$a_{n}=a_{1}(r)^{n-1}$

When Sophia runs the 400 meter dash, her finishing times are normally distributed with a mean of 75 seconds and a standard devia

alukav5142 [94]

Answer: 90% of the time.

Step-by-step explanation: This is because you can add the two different times and the standard time of 75 seconds, divide it all by 3 leaving you with 75.2 and that is 0.2 away from the original between those times all together. Take that 0.2 and subtract it from the 1.1 deviation and you’ll get 0.9 times that by 100 and you get it in a percentage; 90%.
