Range:15
Mean:86
Median:86
Mode:86
Answer:
15, 89, 86, 86
Step-by-step explanation:
To find the range of any data, follow the steps
Step-1: Arrange the set of data in ascending order.
Step-2: Divide the smallest value from highest value. Means, highest value - smallest value.
= 79, 83, 84, 86, 86, 90, 94
= 94 - 79
= 15
To find the mean of any data, follow the steps
Step-1: Add all the numbers.
Step-2: Divide the result by the numbers of observation.
= (79 + 83 + 94 + 86 + 90 + 84 + 86) ÷ 7
Here, we divide it by 7 because, there are 7 numbers in the data.
= 602 ÷ 7
= 86
To find the median of any data, follow the steps
Step-1: Arrange the numbers(given in data) in ascending order.
Step-2: Find the middle number in the set.
= 79, 83, 84, 86, 86, 90, 94
Now, find tee middle number in it.
= 86
See in last, to know, what will be the median, if there will be 2 numbers in the middle.
To find the mode in any data, see that which number is occurring the most.
In this set of data, 86 is occurring the most number of times from others.
= 86
Mode can be more than 1 in a set of data. So, don't get confused that what will be the mode, if you find more than 1 mode in a set of data.
what will be the median, if there will be 2 numbers in the middle?
There will be only 1 median in a set of data.
To know the median if there are two numbers in the middle, just remember the steps which is written down.
Step-1: Add both the middle numbers.
Step-2: Divide the result you get after adding.
For example, to find the median in 79, 83, 94, 86, 90 and 84.
First we need to arrange them in ascending order.
After arranging them in ascending order we will get the result, 79, 83, 84, 86, 94, 90.
So, here there are two numbers in the middle that are 84 and 86.
So, add them and divide it by 2.
= (84 + 86) ÷ 2
= 170 ÷ 2
= 85 is our final answer.
Hope, now you know how to find median if there are two numbers in middle.
How many zeros will be in the product of 5 x 105 = ________? Explain how you know.
Answer:
The is zero 0's in the answer. The way I know is that I put it into an equation, and started solving. I started off by multiplying 5x5=25. Next I noticed the next number I multiply 5 by is 0, so the next value will be 2 because the 2 from 25 was carried over. Finally I multiplied 100x5=500. And 500+25=520.

21 people travelled to a meeting.
12 used a train.
6 used a car.
7 did not use a train or a car.
Some used a train and a car.
Two people are chosen at random from those who used a train.
Find the probability that both these people also used a car.
Answer:
answer = 1/11
Step-by-step explanation:
The addition rule of probability.
P (T + C) = P(T) + P(C) - P(T ∩ C)
The probability that both these people also used a car given that both of them use a train is 1/11.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The number of people who used the train and the car.
P (T U C) = 21 - 7 = 14
P(T) = Probability of the number of people who used the train = 12
P(C) = Probability of the number of people who used the car = 6
From the addition rule of probability.
P (T + C) = P(T) + P(C) - P(T ∩ C)
14 = 12 + 6 - P(T ∩ C)
P(T ∩ C) = 12 + 6 - 14 = 18 - 14 = 4
Now,
Two people are chosen.
P(C/T):
= P(T ∩ C) / P(T)
= [tex]^4C_2[/tex] / [tex]^{12}C_2[/tex]
= (4 x 3 / 2) / (12 x 11 / 2)
= 6 / 6 x 11
= 1/11
Thus,
The probability that both these people also used a car given that both of them use a train is 1/11.

Answer:
-3s + 6
Step-by-step explanation:
In order to find the answer you need to combine like terms. When you combine like terms you need to combine integers that have the same variable in this case 8 and 11 need to be combined due to the fact they both have the variable s.
8s - 11s + 6

Find the slope-intercept form of the line passing
through the point (8,7) and parallel to the line
y = - 2x - 5.
Answer:
y = -2x + 23.
Step-by-step explanation:
If the line is parallel to
y = -2x - 5,
that means it has the SAME SLOPE. Parallel lines have the same slope, but they could have different y-intercepts.
The slope intercept form is:
y = mx + b.
m = slope.
b = y intercept.
In this case, the slope is -2.
So we know the answer will have a slope of -2.
So we can write:
y = -2x + b.
We just have to finish the answer by replacing "b" with a number.
To find out what "b" is, we plug in the point (8,7).
To plug this point in, we replace "x" with 8 and "y" with 7.
7 = -2(8) + b.
7 = -16 + b.
Now to get b by itself to solve for b, we have to add 16 to both sides.
7 + 16 = b.
b = 23.
So our final answer is: y = -2x + 23.

2x+7y=3 and x=-4y with substitution ?
Answer:
x=12
y=-3
Step-by-step explanation:
Because we already know what the value of x, we can use that value, -4y, to substitute it into the equation 2x+7y=3.
2(-4y)+7y=3 Simplify.
-8y+7y=3
-y=3 Divide both sides by -1 (to make y positive).
y=-3
Now, we can substitute y into the other equation, x=-4y.
x=-4(-3) Simplify.
x=12

Given that Tom is paid £15 if he works for less than 7 hours and then paid 1 1/3 times his normal salary if he works more than 7 hours.
Given that he works for 11 hours, hence:
Pay for the first 7 hours = £15 × 7 hours = £105
Pay for the overtime = 1 1/3 × £15 × (11 - 7) = 4/3 × £15 × 4 = £80
Total pay = £80 + £105 = £185
