$30\%=\frac{30}{100}=\frac{3}{10}=\frac{3 \times 3}{10 \times 3}=\frac{9}{30} \\ 
\frac{1}{3}=\frac{1 \times 10}{3 \times 10}=\frac{10}{30} \\ \\
9$

1/3 is bigger.

Clare knows that Priya has a bunch of nickels and dimes in her pocket and that the total amount is $1.25. Write an equation that

Mrrafil [7]

Answer:

The equation that describes the relationship between the number of dimes and the number of nickels in Priya's pocket. is;

$0.05n+0.10d=1.25$

Explanation:

Let n and d represent the number of nickels and dimes in her pocket;

We know that;

1 nickel is 5 cents = 0.05 dollar

1 dime is 10 cents = 0.10 dollar

Also;

n nickels = n times 0.05 dollars

$0.05n$

d dimes = d times 0.10 dollar

$0.10d$

The total is given as;

the total amount is $1.25.

So, we have the equation as;

$0.05n+0.10d=1.25$

Therefore, the equation that describes the relationship between the number of dimes and the number of nickels in Priya's pocket. is;

$0.05n+0.10d=1.25$

Select the correct comparison set a set b O A the typical value is greater is set a the spread is greater in set b

salantis [7]

Answer:

(a)

Step-by-step explanation:

Given

See attachment for sets A and B

Required

The true statement about both sets

First, we calculate the typical values (mean) of set A and set B.

This is calculated as:

$Mean = \frac{\sum fx}{\sum f}$

For A:

$A= \frac{0*1+2*1+5*1+6*1+7*1}{1+1+1+1+1}$

$A= \frac{20}{5}$

$A =4$

For B:

$B = \frac{7 * 1 + 8 *1 + 9 * 2 + 10 * 1}{1+1+2+1}$

$B = \frac{43}{5}$

$B = 8.6$

Here, we can conclude that B has a larger typical value

Next calculate the spread (range) of sets A and B

This is calculated as:

$Range = Highest -Least$

For A:

$A = 7 - 0$

$A = 7$

For B

$B=10 - 7$

$B = 3$

Here, we can conclude that A has a larger spread.

Hence, (a) is true
