Mathematics

Answer:

1) 61, 92, 61, 89, 92, 61

Mode : The number which appears most often in a set of numbers.

61 occurred thrice

89 occurred once

92 occurred twice

Since 61 occurred most often

So, Mode of the given data is 61.

2)82, 105, 247, 119, 94, 202

Mean = \frac{\text{Sum of all observations}}{\text{Total no. of observations}}

So, Mean = \frac{82+105+247+119+94+202}{6}

Mean = 141.5

Thus the mean of the given data is 141.5

3) First week expenditure:  $11.52, $6.48, $5.99, $14.00, and $9.50

Mean = \frac{\text{Sum of all observations}}{\text{Total no. of observations}}

So, Mean = \frac{11.52+6.48+5.99+14.00+9.50}{6}

Mean = 7.915

Now we are given that in the second week, she spent $4 more in total for the 5 lunches than the first week.

So, Mean = \frac{\text{Sum of all observations+4}}{\text{Total no. of observations}}

So, Mean = \frac{11.52+6.48+5.99+14.00+9.50+4}{6}

Mean = 8.581

Increase in the mean in the second week = 8.581-7.915 = 0.666

Hence the increase in the mean for the second week compared to the first is 0.666.

<span>What is the mode of the data set?: 61 (It's the one that repeats most often.)
Mean: 141.5 to find the mean add all of the the numbers then divide by how many numbers are there.

Answer:

  w² +9w +20

Step-by-step explanation:

Multiply it out, collect terms, and write as descending powers of w.

  (5+w)(w+4) = 5w +5·4 +w² +w·4

  = w² +9w +20

(c) Use a calculator to verify that Σ(x) = 64, Σ(x2) = 1118, Σ(y) = 628, Σ(y2) = 87,982, and Σ(x y) = 9,627.
amid [387]

The correlation based on the computation is 0.97.

<h3>How to compute the value?</h3>

It should be noted that the question is that we should simply calculate the correlation which is r.

The correlation will be:

= Σ(x y) / (Σ(x²) × Σ(y²)

= 9627/✓(1118 × 87982)

= 9627 ✓98363876

= 9627/9917.86

= 0.97

Answer:

HCF×LCM=a×b

6×60=a×b

a×b=360

So the numbers are whose product is 360 and LCM is 60

These two numbers can be 6,60 or 12,30
