Let me help you!

What we have so far:
Number of times the event occured = 0
Total number of times the event was performed = 0

We will use the empirical probability formula for this problem:
Empirical probability formula = Number of times the event occured / Total number of times the event was performed

Solving for the porblem:
Empirical probability formula = 0.

*** Without even solving the problem, you can take the word "NO" as a hint that there's simply no chance any woman can beak the 10 seconds barrier in a 100 meter run.

Therefore, there is 0 probability that a woman will break the 10 seconds barrier in a 100 meter run.

The data below are the monthly average high temperatures for New York City. What is the five-number summary? 40, 40, 48, 61, 72,
yawa3891 [41]

Answer:

B) Sample minimum: 40, Sample maximum: 84

Q1: 45, Median: 63, Q3: 77

Step-by-step explanation:

The first step is to write the temperatures in crescent order:

40, 40, 42, 48, 54, 61, 65, 72, 76, 78, 84, 84,

The sample minimum is the lowest value = 40

The sample maximum is the highest value = 84.

Since there are 12 numbers, the sample median is the average between the 6th and 7th terms:

M = \frac{61+65}{2}\\ M=63

The first quartile is the average between the 3rd and 4th terms:

Q_1 = \frac{42+48}{2}\\ Q_1=45

The third quartile is the average between the 9th and 10th terms:

Q_3 = \frac{76+78}{2}\\ Q_3=77

Therefore, the answer is:

B) Sample minimum: 40, Sample maximum: 84

Q1: 45, Median: 63, Q3: 77

A rectangular prism has a volume of 16 cm3 and a total surface area of 40 cm2. A similar prism has length 10 in., width 5 in., a
Kruka [31]
We know that
[volume of the similar prism]=10*5*5----> 250 in³
volume original prism=16 cm³
 1 in³---------> 16.3871 cm³
X----------> 16
x=16/16.3871------> x=0.9764 in³

[volume of the similar prism]=[scale factor]³*[volume original prism]
[scale factor]³=[volume of the similar prism]/[volume original prism]
[scale factor]³=[250]/[0.9764]------> 256.05
scale factor=∛256.05-------> 6.35

<span>the dimensions of the original prism are
1 in-----> 2.54 cm

</span>length 10 in/6.35-------> 1.57 in*2.54 cm/in-----> 4 cm
<span>width 5 in/6.35---------> 0.79 in*2.54 cm/in-----> 2 cm
</span><span>height 5 in/6.35--------> 0.79 in*2.54 cm/in----> 2 cm</span>

name three different pairs of fractions that have the same product when multiplied .explain how you got your answer
Deffense [45]
\frac{5}{10}*\frac{10}{40}=\frac{50}{400}
\frac{2}{8}*\frac{2}{4}=\frac{4}{32}
\frac{1}{4}*\frac{1}{2}=\frac{1}{8}

\frac{1}{8} is obtained by multiplying \frac{1}{2} and <span>\frac{1}{4}
</span>You basically create equivelant fractions for both 1/2 and 1/4 and multiply by each other. This way you get the same result always.
