Required that there must be chaperones for every 25 how many chaperones must there be for 80 students

Answer:

6 chaperones on 80 students.

Step-by-step explanation:

Here is the complete question: School guideline required that there must be 2 chaperones for every 25 students on a school trip. how many chaperones must there be for 80 students?

Given: There must be 2 chaperones on every 25 students.

       

Now, we will use unitary method to solve.

We know 2 chaperones = 25 students

∴ one student required \frac{2}{25}\ chaperones

Next for 80 students, we require= \frac{2}{25} \times 80 = \frac{160}{25}

∴ For 80 students, we require 6.4 \ chaperones, however, we cannot use decimal for number of person, so we can round off the number to 6 chaperones on every 80 students.

Find the equation for the asymptote y=10/x
DochEvi [55]
Actually, this graph has two asymptotes:  a vertical one and a horiz. one.

Note that we cannot divide by zero.  Thus, x = 0 is the vertical asymptote.

Note that as x continues to grow, y tends towards zero.  Thus, y = 0 is the horiz. asy.

wo crafty bacteria fall into a pot of milk which has recently been sterilized. They reproduce at a rate of 4% per day. Determine
RideAnS [48]

Answer:

Number of bacteria after 100 days is 1237.

Step-by-step explanation:

Since bacterial growth is a geometrical sequence.

Therefore, their population after time t will be represented by the expression

S_{n}=\frac{a(r^{n}-1)}{r-1}

Where a = first term of the sequence

r = common ratio of the sequence

n = duration or time

Since first term of the sequence = number of bacteria in the start = 1

Common ratio = r = (1 + 0.04) = 1.04

S_{100}=\frac{1[(1.04)^{100}-1)]}{1.04-1}

       = \frac{(50.5049-1)}{(0.04)}

       = 1237.64 ≈ 1237 [Since bacteria can't be in fractions]

Therefore, number of bacteria after 100 days is 1237.

Three students want to estimate the mean backpack weight of their schoolmates. To do this, they each randomly chose 8 schoolmates and weighed their backpacks. Then as per the given sample data,

(a) The sample means of the backpacks are: 6.375,6.375,6.625

(b) Range of sample means: 0.25

(c)The true statement is: The closer the range of the sample means is to 0, the less confident they can be in their estimate.

For the first sample, mean= 6.375

For the second sample, mean= 6.375

For the third sample, mean= 6.625

Range of sample means=Maximum Mean- Minimum Mean

                                        = 6.625 - 6.375

                                        = 0.25

The students will estimate the average backpack weight of their classmates using sample means, the true statement is:

The closer the range of the sample means is to 0, the more confident they can be in their estimate.

Which expression is equivalent to 24 Superscript one-third?
Ivahew [28]

Answer:

See explanation

Step-by-step explanation:

The given expression is: (24)^{\frac{1}{3}}

Recall that 24=3*8

\implies(24)^{\frac{1}{3}}=(8*3)^{\frac{1}{3}}

Recall again that:

(a*b)^n=a^n*b^n

\implies (8*3)^{\frac{1}{3}}=(8)^{\frac{1}{3}}*(3)^{\frac{1}{3}}

\implies (8*3)^{\frac{1}{3}}=(2^3)^{\frac{1}{3}}*(3)^{\frac{1}{3}}

\implies (8*3)^{\frac{1}{3}}=2^{3*\frac{1}{3}}*(3)^{\frac{1}{3}}

\implies (8*3)^{\frac{1}{3}}=2*(3)^{\frac{1}{3}}

We rewrite in radical form to obtain

\implies (8*3)^{\frac{1}{3}}=2\sqrt[3]{3}

kolezko [41]

Answer:

A section of wall is being framed. A model of the framing work is shown below. Vertical and parallel lines c, d, and e are cut by diagonal transversal b. The uppercase right angle formed by the intersection of lines b and c is angle A. The uppercase left angle formed by the intersection of lines d and b is 125 degrees. Which best describes the relationship between the 125° angle and angle A? They are same side interior angles. Angle A measures 55°. They are alternate interior angles. Angle A measures 125°. They are vertical angles. Angle A measures 125°. They are corresponding angles. Angle A measures 55°.
