Yes,I do 1,110 is a cluster because it’s a very large number for 52 degrees and 189 is because it’s a very large number for 16 degrees.

Hope this helps :)

If the outliers are not included, what is the mean of the data? 76,79,80,82,50,78,83,79,81,82.

natta225 [31]

50 is the only outlier so take 50 out of the set then add the other 9 data points and divide by 9.
76 + 79 + 80 + 82 + 78 + 83 + 79 + 81 + 82 = 720 / 9 = 80

The masses to the nearest kilogram of nine men were:

serious [3.7K]

Answer:

82 kg

Step-by-step explanation:

To find the mean of a set of values, we must add them up and divide by the number of values.

Step 1, adding the values:

$75+68+78+82+85+90+88+92+76=\\734$

Step 2, dividing by the # of terms:

There are 9 terms in total.

$\frac{734}{9} =\\81.556$

To the nearest kilogram, we can round 81.556 into 82.

The mean mass of the 9 men was $\fbox{82}$ kg.

I hope this helps! Let me know if you have any questions :)

A recipe calls for 1/4

Tom [10]

So, if we break it down, this is just easy math! First we divide 16 tablespoons/4 and that gives us 4, then we multiply 1*3 and that equals 3! So 3*4 is equal to 12. So there are 12 teaspoons of broth in 1/4 cup of broth! Hope this helped! Brainliest is always appreciated.

−3x + y = 4, −9x + 5y = −1 find x and y

katrin [286]

Answer:

9x - 3y = -12

-9x +5y = -1

2y = -13

y = -13/2

-3x - 13/2 = 8/2

-3x = 21/2

-6x = 21

x = -21/6 = -7/2

(-7/2, -13/2)

If f(x) = 2x2^2 + 1 and g(x) = x^2 - 7, find (f+g) (x)

Sveta_85 [38]

(f+g)(x) = f(x) + g(x)

= 2x² + 1 + x² - 7

= 3x² - 6
