Which statement correctly compares the spreads of the distributions?

Pavlova-9 [17]

Answer:

Step-by-step explanation:

Mode definition is the number which appears most often in a set of numbers. Since the mode is the same amount of bubbles it is not A.

The range of a set of data is the difference between the highest and lowest values in the set.

To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

The data has already been ordered for you so you take the highest number and subtract the smallest number.

By what percent will a fraction decrease if its numerator is decreased by 85% and its denominator is decreased by 25%??

belka [17]

Answer:

106.67%

Step-by-step explanation:

85% as a fraction is 4/5

25% as a fraction is 3/4

<h2> $\frac{4}{5}$ / $\frac{3}{4}$ = $\frac{16}{15}$ </h2>

Convert 16/15 to a decimal: 1.067

Multiply: 1.067 · 100= 106.67%

3x-(2x-1)=7x-(3*5x)+(-x+24)

Paraphin [41]

Answer:

$\boxed{\boxed{\sf x=\frac{23}{10}}\: \sf or \:\boxed{x=2.3}}$

_________________

$\boxed{\sf Step\: By\:Step:- }$

$\sf 3x-\left(2x-1\right)=7x-\left(3\times \:5x\right)+\left(-x+24\right)$

<u>Remove the parentheses:</u>

$\to\sf 3x-\left(2x-1\right)=7x-3\times \:5x-x+24$

<u>Combine like terms:</u>

$\sf ^*7x-x=6x$

$\to\sf 3x-\left(2x-1\right)=6x-3\times \:5x+24$

<u>Multiply 3 and 5x = 15x:-</u>

$\to\sf 3x-\left(2x-1\right)=6x-15x+24$

<u>Combine like terms:</u>

$\sf ^*6x-15x=-9x$

$\to\sf 3x-\left(2x-1\right)=-9x+24$

<u>Expand: 3x-(2x-1)= x+1</u>

$\to\sf x+1=-9x+24$

<u>Subtract 1 from both sides:</u>

$\to\sf x+1-1=-9x+24-1$

$\to\sf x=-9x+23$

<u>Add 9x to both sides:</u>

$\to\sf x+9x=-9x+23+9x$

$\to\sf 10x=23$

<u>Divide both sides by 10:</u>

$\to\sf \cfrac{10x}{10}=\cfrac{23}{10}$

$\to\sf x=\cfrac{23}{10}$
