Louis wants to carpet the rectangular floor of his basement. The basement has an area of 980 square feet. The width of the basem

Serhud [2]

This problem requires a system of equations.

Let x be the length and y be the width.

xy = 980 x = 5y

Substitute 5y for x.

5y(y) = 980
5y² = 980
y² = 980/5
y² = 196
y = √196
y = 14 feet

Substitute 14 for y.

x = 5y
x = 5(14)
x = 70 feet

The length is 70 feet.

Miley is trying to solve the following riddle the sum of three consecutive integers is 84 what are the integers

oee [108]

Answer:

Three consecutive numbers are 27,28,29

Step-by-step explanation:

Given : The sum of three consecutive integers is 84.

To find : What are the integers?

Solution : Let three consecutive numbers $x, x+1, x+2$

So, according to given situation 'sum of three consecutive integers is 84'.

$x+x+1+x+2=84$

$\Rightarrow 3x+3=84$

$\Rightarrow 3x=84-3=81$

$\Rightarrow x=\frac{81}{3}$

$\Rightarrow x=27$

So, $x=27$

$x+1= 27+1=28$

$x+2=27+2=29$

Therefore, three consecutive numbers are 27,28,29

Zigmanuir [339]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data :

114, 261, 319, 183,654,313,58,98,335,324,52,125,342,66,321,893,690,798,201,74,632,216,76,155,161,304,530,1110,93,631,75,344,264,1120,122,45,304,192,316,63

USING CALCULATOR :

The mean(m) of the data: = ΣX/n

n = sample size = 40

m = 12974/40

m = 324.4

Median = ((n + 1)/2) th term = 41/2 = (20 + 21)th term / 2

= (261 + 264) / 2 = 262.5

Standard deviation (s) = sqrt(Σ(x - m)²/n))

s = 281. 74

B.) Coefficient of skewness (Ks) :

3(mean - median) / standard deviation

3(324.4 - 262.5) / 281.74

= 0.66

Mild positive skewness Given a positive skew Coefficient value.

(d-1) Are there any outliers?

Yes

Four outliers

(d-2) What are the limits for outliers? (Round your answers to 1 decimal place. Negative amounts should be indicated by a minus sign.)

Lower bound = Q1 - (1.5 * IQR)

Upper bound = Q3 + (1.5 * IQR)

IQR = Q3 - Q1

Q3 = upper quartile = 343 ; Q1 = 106 ; Q2 = 262.5

IQR = 343 - 106 = 237

Lower bound = 106 - (1.5 * 237) = - 249.5

Upper bound = 343 + (1.5 * 237) = 698.5

-249.5 ≤ X ≤ 698.5
