A number is between 10 and 15. It has prime factors of 2 and 3. What is the number?
The number in between 10 and 15 and having prime factors of 2 and 3 is 12.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
The integer between 10 and 15 are,
11,12,13,14
The prime factors of 2 and 3 will be given as,
[tex]2^{a} \times 3^{b}[/tex] where a and b can be positive.
Since, 12 = 2² × 3¹
Thus, 12 is the only number that is the prime factor of 2 and 3 both.
Hence "The number between 10 and 15 and having prime factors of 2 and 3 is 12".

An athlete runs 200 metres race in 24 seconds. what is his speed in km/h
Answer:(29.85km/h)
Step-by-step explanation:
1000m=1km
200m=x [x=(200m/1000m)x1km]
x=0.2km
3600second= 1 hour
24 seconds =b [b=(24s/3600s)x1 hour ]
b=0.0067(in 2 decimal place)
velocity in km/h will be
0.2km/0,0067secs
=29.85(in 2 decimal place)
Answer:
speed = 30 km/h
Step-by-step explanation:
We are told that a 200 metres race is run by an athlete in 24 seconds. The question then asks us to calculate the athlete's speed in km/h.
To do this, let's first convert the given data into the required units:
• Converting from metres to kilometres:
To convert from 200 metres to kilometres, we have to divide it by 1000:
200 m = 200 m ÷ 1000 m/km
= 0.2 km
• Converting from seconds to hours:
To convert 24 seconds to hours, we have to divide it by 3600:
24 s = 24 s ÷ 3600 s/h
= [tex]\frac{24}{3600}[/tex] h
Now that we have the data in the appropriate units, we can use the following formula to calculate speed:
[tex]\boxed{\mathrm{speed = \frac{distance}{time}}}[/tex]
⇒ speed = [tex]\mathrm{\frac{0.2 \ km}{24/3600 \ h}}[/tex]
⇒ speed = 30 km/h
Therefore, the speed of the athlete is 30 km/h.

The value of ∠WXY = 20.
What is Exterior angle theorem?
The exterior angle theorem describes the connection between the two remote angles in a triangle and the external angle created by an extended side outside the triangle.
Given: Measure of angle YWX = (3x + 17) °
Measure of angle WXY = (3x + 2) °
Measure of angle XYZ = (10x − 5) °
Therefore, m∠XYZ = m∠YWX + m∠WXY (exterior angle theorem)
⇒ (10x − 5) ° = (3x + 17) ° + (3x + 2) °
Solve for x,
⇒ 10x - 5 = 3x + 17 + 3x + 2
⇒ 10x - 6x = 17 + 7
⇒ 4x = 24
⇒ x = 6
∴ ∠WXY = (3x + 2) = 18 + 2 = 20
Hence, value of ∠WXY = 20.

The above function is an absolute value function
Next, we plot the graph using a graphing calculator

How to describe the transformation from the parent function?From the question, we have the following function that can be used in our computation:
f(x) = |x| --- the parent function of an absolute value function
g(x) = -|x + 3| - 4 -- the transformed function
First, we have the transformation to be:
From f(x) = |x| to f'(x) = |x + 3|
This means the function is translated left by 3 units
Next, we have:
From f'(x) = |x + 3| to f'(x) = -|x + 3|
This means the function is reflected across the x-axis
Lastly, we have:
From f'(x) = -|x + 3| to g(x) = -|x + 3| - 4

how healthy are the employees at direct marketing industry? a random sample of 12 employees was taken, and the number of days each was absent for sickness was recorded (for a 1-year period). use these data to create a 95% confidence interval for the population mean days absent for sickness.
The sample mean is 5.0833 and the standard deviation is 3.476 and the confidence interval is (2.87, 7.29).
In the given question, a random sample of 12 employees was taken, and the number of days each was absent for sickness was recorded (for a 1-year period).
Using these data to create a 95% confidence interval for the population mean days absent for sickness
2 5 3 7 10 0 6 8 5 11 3 1
a) We have to find the sample mean and the standard deviation (round to two decimal places).
The sample mean;
X = 2+5+3+7+10+0+6+8+5+11+3+1/12
X = 61/12
X = 5.0833
Now the standard deviation
SD = √[{x(1)-X)^2+(x(2)-X)^2…………….(x(12)-X)^2}/N]
After solving using that formula;
SD = 3.476
b) 95% confidence in interval for the population mean days absent for sickness.
Lower Bound = X - t(α/2)*s/√n
Upper Bound = X + t(α /2)*s/√n
where
α /2 = (1 - confidence level)/2 = 0.025
X = sample mean = 5.083333333
t(α/2) = critical t for the confidence interval = 2.20098516
s = sample standard deviation = 3.476108936
n = sample size = 12
df = n - 1 = 11
Thus,
Lower bound = 2.874719086
Upper bound = 7.291947581
Thus, the confidence interval is (2.87, 7.29).

(a) if 2/3 of all kissing couples exhibit this right-leaning behavior, what is the probability that the number in a sample of 127 who do so differs from the expected value by at least as much as what was actually observed? (round your answer to four decimal places.)
The probability that the number in a sample of 127 who do so differs from the expected value is 0.6198.
How to calculate probability?
The critical value, according to the data, is 84. the following will be the mean:
= np = 127 × 2/3 = 84.6
The standard deviation is also 5.3748. The corresponding z score will be:
= (84 - 86.67)/5.3748
= -0.50.
Therefore, the left tailed area will be:
P(z < -0.50) = 0.3099
Since, it's two tailed, we'll multiply by 2. This will be:
= 2 × 0.3099
= 0.6198
In conclusion, the probability is 0.6198.

evaluate √24−x when x = 6. write the answer in simplified radical form.
Given √24−x when x = 6 in simple radical form is 3*√2.
What is radical form?Simply put, simplifying a radical eliminates the need to find any further square roots, cube roots, fourth roots, etc.
Additionally, it entails eliminating any radicals from a fraction's denominator.
The square root of 2 or root 2 is represented using the square root symbol √ and written as √2 whose value is 1.414.
So, we have:
√24−x when x = 6
Thus we must now calculate the square root of 18.
The square root, if you're allowed to use a calculator, is 4.242.
If not, however, let's come as close as we can:
√(9 * 2)
Since 3 is the square root of 9:
