First, we have to calculate the remaining amount of money after the cost of the ticket. It is 200 - 87.96 = 112.04 Dividing this number to 30, we can find the maximum number of t-shirts she can buy. It is less 4 and more than 3. So that, the final answer is 3.
Line plots are used to represent data using lines and dots
The difference between the greatest amount of water and the least is 1/2
From the line plot (see attachment), we have the following parameters:


<h3>Calculating the difference</h3>
The difference (d) is then calculated as:

So, we have:

Subtract the common terms (8)

Take LCM


Reduce the fraction

Hence, the difference between the greatest amount of water and the least is 1/2

If Sandra mixes <em>x</em> L of 65% solution with <em>y</em> L of 90% solution, then the resulting mixture has a total volume of
<em>x</em> + <em>y</em> = 500
litres, and it contains
0.65<em>x</em> + 0.90<em>y</em> = 0.75 (500) = 375
litres of alcohol.
Solve the first equation for <em>y</em> :
<em>y</em> = 500 - <em>x</em>
<em />
Substitute this into the second equation and solve for <em>x</em> :
0.65<em>x</em> + 0.90 (500 - <em>x</em>) = 375
0.65<em>x</em> + 450 - 0.90<em>x</em> = 375
75 = 0.25<em>x</em>
<em>x</em> = 300
Solve for <em>y</em> :
<em>y</em> = 500 - 300
<em>y</em> = 200
So, Sandra should mix 300 L of 65% solution with 200 L of 90% solution.
Respuesta: 4.5 pies que puede comprar si tiene $ 11.25
Explicación paso a paso:
Dado que hemos dado que
Costo de los dulces por pie = $ 2.50
Dinero total que gastó en dulces = $ 11.25
Sea x el número de pies que puede comprar
Ahora, según la pregunta, obtenemos eso,
Entonces, 4.5 pies que puede comprar si tiene $ 11.25.
Answer:
b) 1.34
Step-by-step explanation:
The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:

For the largest 9%, the score is 100% - 9% = 91% = 0.91
From the normal distribution table, the z score that corresponds to 0.91 is 1.34
