The reading on a car’s speedometer may have an error up to 6.25%. The speed limit on a road is 65 miles per hour.

No.
The speed limit is 65. Accounting for a 6.25% error, then there is a range of speeds that could be considered 65.
The range:
65(0.9375) = 60.9375
65(1.0625) = 69.0625
So, any speed within that range is within the error zone. Therefore, a reading of 67 is not necessarily speeding.

Please solve for me. C=1/2x(a+w)

Gnoma [55]

Answer:

C= 1/(2ax+2aw)

Step-by-step explanation:

C=1/2x(a+w)

Multiply a and w by 2x. Take note of the sign.

C= 1/(2ax+2aw)

when writing your answer, you don't need the brakets. I just put them so you'd understand that all those characters in the bracket are the denominator.

Please rate 5 stars, thanks, give brainliest. Thanks.

What is ∑n=15[5(−2)n−1] equal to?

kicyunya [14]

Answer:

Although the notation is sloppy, I will assume based on former questions of the same that "∑n=15[5(−2)^n−1]" translates mathematically to . Please correct me, though, if this in incorrect.

Anyway, there is neat formula that will deal with question very quickly. It is the following:

Sn is the sum of the geometric series

a1 is the first term in the series

r is the common ratio

n is the number of terms in the finite geometric series

Let's use this formula to our advantage! However, there are two variables that we do not know: a1 and n. Let's start with a1.The first term in the series is when n=1, so let's determine what that is.
