Answer:
1. The speed of the truck, S = D/T.
2. The formula that connects D and T is: S = D/T.
3. The coefficient of variation, k, is the ratio of the standard deviation to the mean speed.
Step-by-step explanation:
a) The speed of a truck at a fixed speed is given as the distance covered by the truck divided by the time it takes the truck to cover the said distance. This implies that speed is a function of distance and time. However, this formula represents the mean speed. There are variations in speed.
b) If the truck covers a distance of 60 kilometers, for example, under 3 hours, we can conclude that the speed is 20 kilometers per hour (60/3) or 20 km/hr.
Steph age is 7/5 times of the total of students in this class minus 22. If steph is 13 years old , write an equation to find the total students in the class.
Step-by-step explanation:
Let us take:
Steph's age = x
No. of students in the class = y
Given that,
x = 13
also,
x = 7/5y - 22
That gives,
13 = 7/5y - 22
13 + 22 = 7/5y
35 = 7/5y
35 × 5/7 = y
5 × 5 = y
25 = y
Find the value of X and Y. If your answer is not an integer, express it in simplest

Assume that you have an ordinary deck of 52 playing cards. How many possible 7- card pocker hands are there that contain at least one face card (Jack, Queen, or King)?
Answer:
There are 115141000 possible ways.
Step-by-step explanation:
Since it is a 7 – card pocker hands, then the total number of poker hands will be:
[tex]\binom{52}{7}[/tex]
Also, the total number of hands without figure cards is
[tex]\binom{40}{7}[/tex]
This is because there are 12 cards with figures (4 x J, Q, K).
Therefore, the number of hands with at least one figure will be:
[tex]\binom{52}{7} - \binom{40}{7}[/tex]
And this would be
133784560 – 18643560 = 115141000

m< AED = 16y + 10. Find the value of y so that ED I AB.
Full question attached:
Answer and explanation:
To calculate y in the equation <AED=16y+10 we first find the value of angle AED from the diagram(attached)
From the diagram, we can see that <AED = 180 degrees given that <AED is angle on a straight line=180 degrees.
The line AB is therefore perpendicular to line ED
Hence we calculate y in the equation <AED= 16y+10
180= 16y+10
180-10=16y
16y=170
y=170/16
y= 10.625

How do you do letter c?
Answer:
1056
Step-by-step explanation:
dP/dt = 0.0013P (1 − P/6200)
Euler's method states:
yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)
Substituting:
P(t+1) = P(t) + (1) [0.0013 P(t) (1 − P(t)/6200)]
P(t+1) = P(t) + 0.0013 P(t) (1 − P(t)/6200)
We know that when t=0, P=1000.
P(1) = P(0) + 0.0013 P(0) (1 − P(0)/6200)
P(1) = 1000 + 0.0013 (1000) (1 − 1000/6200)
P(1) = 1001.1
Repeating the pattern, we get P(50) is:
P(50) = 1055.7
Rounded to the nearest whole number, P(50) = 1056.
The opera theater manager believes that 23#% of the opera tickets for tonight's show have been sold. If the manager is accurate, what is the probability that the proportion of tickets sold in a sample of 869869 tickets would differ from the population proportion by less than 3%3%
Answer:
0.9642
Step-by-step explanation:
Sample proportion p follows a Normal distribution with mean = p0 = 0.23 and Standard deviation = √P0(1 - P0) / n = √0.23(1-0.23) / 869 = 0.0143
Then Z = p - mean / Standard deviation = X - 0.23 / 0.01343
P(0.2<p<0.26) = P(p<0.26) - P(p<0.2)
= P(p-023/0.0143 < 0.26-0.23/0.0143) - P(p-0.23/0.0143 < 0.2-0.23/0.0143)
= P(Z < 2.1) - P(Z < -2.1)
= 0.9821 - 0.0179
= 0.9642
Jose gets his hair cut for $12. He gives his barber a
15% tip. How much does he give the barber for a tip?
(If you have big brain plz help me)
Answer: $3

Jose gives the barber a $1.80 tip.
What is a percentage?A percentage is a ratio or number that may be expressed as a fraction of 100. Moreover, it is denoted by the sign "%."
Given information:
Jose gets his hair cut for $12.
He gives his barber a 15% tip.
To calculate the tip, we need to find 15% of the cost of the haircut.
15% can be written as a decimal as 0.15.
So, the tip amount is:
0.15 x $12 = $1.80
Therefore, Jose gives the barber a $1.80 tip.

What is the product of 7×-6 1/8
Answer:
-42.875 or -42 7/8
Step-by-step explanation:
you can turn -6 1/8 into a decimal: -6.125 and multiply it with 7.
The product of the fraction 7 x -(6 1/8) is -42.875 or in fraction form -42 7/8.
We have expression: 7 x -(6 1/8).
First, write the mixed fraction into improper fraction as
Numerator = 8 x 6 + 1 = 49
Denominator = 8
Now, the product will be
7 x -(6 1/8)
= 7 x (-49/8)
= 7 x (-6.125)
= -42.875
