Find the circumstances

Answer:

Option B: 0.4

Step-by-step explanation:

We have 20 dots.

Such that each column represents the repetitions for each proportion.

So:

0.1 -> 3 times

0.2 -> 1 time

0.3 -> 4 times

0.4 -> 6 times

0.5 -> 3 times

0.6 -> 3 times

Now we can compute the mean of these values, and that will be the best estimation we can make with the given data.

Remember that for a set of N values:

{x₁, x₂, ..., xₙ}

The mean is:

[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]

In this case we have the set of 20 points described above, then the mean is:

[tex]M = \frac{3*0.1 + 1*0.2 + 4*0.3 + 6*0.4 + 3*0.5 + 3*0.6}{20} = 0.37[/tex]

Rounding to the first place after the decimal point, we get:

M = 0.4

Then the correct option is option B.

The average speed of Sam's race car is equal to 20 kilometers per hour.

In this question we find the case of a race car being displaced in a race whose length (s) is 10.6 kilometers, a distance traveled in a time (t) of 31 minutes and 46 seconds (1906 seconds). The average speed (v), in kilometers per hour, is described by the following formula that assumes an hypothetical constant speed:

v = s / t

Where:

First, convert time into hours:

t = (31 min) · (1 hour / 60 min) + (46 s) · (1 hour / 3600 s)

t = 0.529 h

Second, calculate the average speed:

v = (10.6 km) / (0.529 h)

v = 20.038 km / h

v = 20 km / h

The slope of the line is 2.

Option A is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

From the line,

Coordinates are:(2, 4) and (4, 8)

Now,

(2, 4) = (a, b) and (4, 8) = (c, d)

Slope.

= (d - b) / (c - a)

= 8 - 4 / 4 - 2

= 4 / 2

= 2

Jayden had to skim through an amount of 75 pages, in the given word problem.

A word problem is a few sentences that describe a "real-life" scenario in which a problem must be solved using a mathematical calculation.

Word problems are regarded as an important part of the primary curriculum because they require children to apply their knowledge of various concepts to'real-life' scenarios.

Let S = no. of skimmed pages

Let R = no. of read pages

Then S + R = 275

So R = 275 - S

Reading rate = 15 min/10 pages

Skimming rate = 10 min/15 pages

Total time to finish book = 350 min

So,

(R)(Reading rate) + (S)(Skimming rate) = 350 minutes

Substituting the values:

(275-S)(15/10) + (S)(10/15)=350

Multiplying equation through by 30 yields:

12375 - 45S + 20S = 10500

Combine terms

1875=25S

S = 75

Thus, Jayden had to skim through an amount of 75 pages.

fundamentals of probability A probability is a numerical representation of the likelihood or possibility of an event occurring. Probabilities can be expressed as proportions with a 0–1 range or as percentages with a 0%–100% range.

Here,

The likelihood that one of the 68 seniors graduating this year will have their birthday coincide with graduation day is given here.

As a result, this issue can be modeled using a binomial probability model with a success chance of 1/365.

Given: The likelihood of exactly 1 success after 68 attempts.

=> P(x=1) = 68!/ (68-1)!  * 1/365

=>  68/365

The equations are n + s = 76 and 2n + 1.50 s = 125.

let n = number of Nachos sold

let s = number of sodas sold

Two equations are presented to us, and we can use them together to solve one variable at a time.

Eq. 1: n + s = 76

Eq. 2: 2n + 1.50 s = 125

So, s = 76 - n

Put (76 - n) for s in the second equation

2n + 1.50 (76 - n) = 125

2n + 114 - 1.50 n = 125

2n - 1.50 n + 114 = 125

0.5n + 114 = 125

0.5n = 125 - 114

0.5n = 11

n = 22

s = 76 - 22

s = 54

==========================================================

Explanation:

The units for each are in feet.

The formula tying together all three variables is

P = 2(L+W)

which is the same as saying

P = 2L+2W

We can think of it having two copies of L and two copies of W, four sides total, added together to get the full perimeter.

I'll go with the first version. Plug in the given values and solve for L

P = 2(L+W)

2(L+W) = P

2(L+144) = 580

L+144 = 580/2

L+144 = 290

L = 290-144

L = 146 feet is the length

---------------

We can confirm this by saying

P = 2(L+W) = 2(146+144) = 2*290 = 580

Or we could say

P = 2L+2W = 2*146+2*144 = 292+288 = 580

or,

P = L+W+L+W = 146+144+146+144 = 580
