Given data is {4.7,8.51,6.5,7.42,9.64,7.2,9.3}

Now question says to find the mean of the given data.

Mean is also called average. Which can be found by adding given terms then divide the sum by total number of terms in the given data set.

Mean=\frac{4.7+8.51+6.5+7.42+9.64+7.2+9.3}{7}

Mean=\frac{53.27}{7}

Hence final answer is mean = 7.61

Answer:

x = <u>12/5</u>

Step-by-step explanation:

Since the original is 10 and the second is 6, that means that the scale is 10:6 or 5:3.  It can also be related as %60 of the length.

<u>Step 1:  Make an equation</u>

10/6 = 4/x

<u>Step 2:  Cross Multiply</u>

10x = 24

<u>Step 3:  Divide</u>

10x / 10 = 24 / 10

24/10 = 12/5

x = 2.4

Triangle ABC is shown the measure of the interior angle at point A is 40 and the exterior angle point C is 102
mixas84 [53]

Answer:

∠C (Interior) =78°

∠B (Interior) = 62°

Step-by-step explanation:

Given:

∠A (Interior) = 40°

∠C (exterior) = 102°

Computation:

∠C (Interior) = 180° - 102°

∠C (Interior) =78°

∠B (Interior) = 180° - ∠A (Interior) - ∠C (Interior)

∠B (Interior) = 180° - 78° - 40°

∠B (Interior) = 180° - 118°

∠B (Interior) = 62°

What is 18 divided by 0.2 and how?
kati45 [8]
0.2 is the same as 2/10

18/(2/10)

As you may have learned in school, when you divide a fraction, you flip the fraction in the denominator, and change it to multiplication

18/(2/10) becomes 18 x (10/2)

multiply normally

18 x 10 = 180

divide to find answer

180/2 = 90

90 is your answer

hope this helps

Remember, when you meet this problem, flip the second fraction, and change the division sign into multiplication. (always second, never first (if first is a fraction)).
