The twenty units of potatoes illustrates the measure of central tendency and probability
The modal weight, mean, and medianStart by sorting the dataset:
0.19; 0.28; 0.55;
0.62; 0.68; 0.77;
0.88; 0.89; 0.98;
0.99; 1.11; 1.22;
1.22; 1.22; 1.33;
1.44; 1.48; 1.68;
1.77; 1.99
The highest occuring element is 1.22 with a frequency of 3
The two middle elements are 0.99 and 1.11.
The mean of these two middle elements is: 0.5 * (0.99 + 1.11) = 1.05
The mean of the whole dataset is:
Mean = (0.19+ 0.28+ 0.55+ 0.62+ 0.68+ 0.77+ 0.88+ 0.89+ 0.98+ 0.99+ 1.11+ 1.22+1.22+ 1.22+ 1.33+ 1.44+ 1.48+ 1.68+1.77+1.99)/20
Mean = 1.06
Hence, the modal weight is 1.22, the mean is 1.06, and the median is 1.05
The probabilities(a) at least 1.1 kg
There are 10 potatoes that weigh at least 1.1 kg.
So, the probability is:
P = 10/20
P = 0.5
(b) more than 3.5kg
There are 0 potatoes that weigh more than 3.5 kg.
So, the probability is:
P = 0/20
P = 0
(c) below 0.50kg
There are 2 potatoes that weigh below 0.50 kg.
So, the probability is:
P = 2/20
P = 0.1
The Variance of the weight.
This is calculated as:
Var = [tex]\sum[/tex](x - mean)^2/n
This gives
Var = [(0.19 - 1.06)^2 + (0.28 - 1.06)^2 + (0.55 - 1.06)^2 + (0.62 - 1.06)^2 + (0.68 - 1.06)^2 + (0.77 - 1.06)^2 + (0.88 - 1.06)^2 + (0.89 - 1.06)^2 + (0.98 - 1.06)^2 + (0.99 - 1.06)^2 + (1.11 - 1.06)^2 + (1.22 - 1.06)^2 + (1.22 - 1.06)^2 + (1.22 - 1.06)^2 + (1.33 - 1.06)^2 + (1.44 - 1.06)^2 + (1.48 - 1.06)^2 + (1.68 - 1.06)^2 + (1.77 - 1.06)^2 + (1.99 - 1.06)^2]/20
Evaluate
Var = 0.22
This means that:
The expectation of the squared deviation of the random variable from the mean is 0.22 kg

[tex]\sqrt{x} +4-3=1\\\sqrt{x} +4=4\\\sqrt{x} =0[/tex]
Answer: x=12
√x+4 - 3 = 1
(√x+4 - 3) + 3 = 1 + 3
√x + 4 = 4
(√x+4)^2 = 4^2
√(x+4)^2 = 16
x+ 4 = 16 (cancels out the square root)
(x + 4) + (-4) = 16 + (-4)
x + 4 - 4 = 16 - 4
And then just solve it out
x = 12

Hello!
To have points with whole numbers, multiples of 3 need to be used for x.
x = 3
y = (1/3)(3)²y = (1/3)(9)y = 3
x = 6
y = (1/3)(6)²y = (1/3)(36)y = 12
x = 9
y = (1/3)(9)²y = (1/3)(81)y = 27
x = 12
y = (1/3)(12)²y = (1/3)(144)y = 48
x = 15
y = (1/3)(15)²y = (1/3)(225)y = 75

Gavyn, Pip and Mark share £102 in a ratio 1:2:3. How much money does each person get?
Answers
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio , 1 + 2 + 3 = 6 parts
divide the amount by 6 to find the value of one part of the ratio
£102 ÷ 6 = £17 ← value of 1 part of the ratio , then
2 parts = 2 × £17 = £34
3 parts = 3 × £17 = £51
Gavyn gets £17
Pip gets £34
Mark gets £51
G=£17
P=£34

9. Frigid Boards purchases one of its snowboards for $395 less a retail trade discount of 15% and a loyalty discount of 4%. Its markup on selling price percentage on all snowboards is 21%. At the end of the season, any leftover snowboards are marked down by 10%. What is the sale price for the snowboard?
Answers
The sale price for the snowboard after the trade and loyalty discount of 15% and 4% will be 351.01 dollars.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
Frigid Boards purchases one of its snowboards for $395 less a retail trade discount of 15% and a loyalty discount of 4%. Then the price of the snowboards will be
⇒ $ 395 × 0.85 × 0.96
⇒ $ 322.32
Its markup on selling price percentage on all snowboards is 21%, then we have
⇒ $ 322.32 × 1.21
⇒ $ 390.01
At the end of the season, any leftover snowboards are marked down by 10%, then we have
⇒ $ 390.01 × 0.90
⇒ $ 351.01

$15080
Step-by-step explanation:
ok so i havent done these in a while but basically.
First, we need to find out what the 6% is.
[tex]\frac{5}{100} \times \frac{11600}{1}[/tex]
5/100 because it's PERCENT, and well we need to put the 11600 out of 1.
Wich gives us
$580. THen, we multiply that by 6, (6 years). Which gives us
$3480. Now, we add that to the $11600. WHich gives us
$15,080.
