Answer: The required length of BM is 32 units.

Step-by-step explanation: Given that the point M is the midpoint of the line segment AB where

$AM=2x+8,\\\\BM=3x-4.$

We are to find the length of BM.

Since the point M is the midpoint of the segment AB, so we must have

$AM=BM\\\\\Rightarrow 2x+8=3x-4\\\\\Rightarrow 3x-2x=8+4\\\\\Rightarrow x=12.$

Therefore, the length of BM is given by

$BM=3\times12-4=36-4=32.$

Thus, the required length of BM is 32 units.

At the north campus of a performing arts school, 10% of the

Alecsey [184]

There were 600 students at the north campus and 400 students at the south campus.

<h2 /><h3><u>Calculus</u></h3>

To determine, if 42% of the 1000 students at the east campus are music majors, how many students did the north and south campuses have before the merger, the following calculation must be performed:

0.10X + 0.90Y = 420
1000 x 0.42 = 420
500 x 0.10 + 500 x 0.90 = 50 + 450 = 500
600 x 0.10 + 400 x 0.90 = 60 + 360 = 420

Therefore, there were 600 students at the north campus and 400 students at the south campus.

Use the minimum and maximum data entries and the number of classes to find the class width, the lower class limits, and the uppe

deff fn [24]

Answer:

The class width is $C_w \approx 13$

Step-by-step explanation:

From the question we are told that

The upper class limits is $max = 121$

The lower class limits is $min = 14$

The number of classes is $n = 8 \ classes$

The class width is mathematically represented as

$C_w = \frac{max - min}{n }$

substituting values

$C_w = \frac{121 - 14}{8 }$

$C_w = 13.38$

$C_w \approx 13$
