If isme estimated that there are 50 students in the seventh grade class but there are actually 40 what is isme’s percent error?
Temka [501]

The percent error is 25 %

<em><u>Solution:</u></em>

Given that it is estimated that there are 50 students in the seventh grade class, but there are actually 40

<em><u>To find: percent error</u></em>

Percent error is the difference between a measured and known value, divided by the known value, multiplied by 100%

<em><u>The formula for percent error is given as:</u></em>

\text{ percent error }=\frac{\text { approximate value }-\text {exact value}}{\text { exact value }} \times 100$

Here, exact value = 40 and approximate value or estimated value = 50

Substituting the values in above formula,

\begin{aligned}&\text { percent error }=\frac{50-40}{40} \times 100\\\\&\text { percent error }=\frac{10}{40} \times 100=\frac{100}{4}=25\end{aligned}

Thus the percent error is 25 %

What are the coordinates of the point on the directed line segment from (4, -3)(4,−3) to (9, -8)(9,−8) that partitions the segme
jekas [21]

Answer:

  (7, -6)

Step-by-step explanation:

You want to find point X on the segment from A to B such that ...

  (X -A)/(B -X) = 3/2

  2(X -A) = 3(B -X) . . . . . . cross multiply

  2X -2A = 3B -3X . . . . . eliminate parentheses

  5X = 2A +3B . . . . . . . . add 3X +2A

  X = (2A +3B)/5 . . . . . . . divide by 5

Filling in the given points for A and B, we have ...

  X = (2(4, -3) +3(9, -8))/5 = (8+27, -6-24)/5 = (35, -30)/5

  X = (7, -6)

The point that divides the segment in the proportions 3:2 is (7, -6).

B(n)=−4−2(n−1)<br> What's the 12th term in the sequence?
marysya [2.9K]

The 12th term in the sequence is -26.

Given,

B (n) = -4 – 2(n – 1)

We have to find the 12th term in the sequence:

To find the nth term in an arithmetic sequence:

An arithmetic sequence's nth term is determined by the formula a = a + (n - 1)d. The common difference, or d, is the difference between any two consecutive terms in an arithmetic series; it can be calculated by deducting any pair of terms starting with a and an+1.

Here,

First term, a = -4

Common difference, d = -2

nth term = 12

Now, let’s find 12th term

B(n) = -4 -2(n – 1)

B(12) = -4 – 2(12 – 1)

B(12) = -4 -2(11)

B(12) = -4 -22

B(12) = -26

That is, the 12th term in the sequence is -26.
