3. At a bargain store, Tanya bought 4 items that each cost the same amount. Tony bought 5 items that each cost the same amount,

but each was $1.25 less than the items that Tanya bought. Both Tanya and Tony paid the same amount of money. What was the individual cost of each person's items? (a) Write an equation. Let x represent the cost of one of Tanya's items. (b) Solve the equation. Show your work. (c) Check your solution. Show your work. (d) State the solution in complete sentences

We'll do it in cents and convert when we have to.

Tanya paid x per item, a total of 4x.

Tony paid x-125 per item (in cents) for a total of 5(x-125)

4x = 5(x-125)

4x = 5x - 625

x = 625 = $6.25  

Check:

4(625) = 2500

5(625-125)=2500, same, checks

Answer: Tanya paid $6.25 per item, Tony $5.00 per item

How can I express this as a single power with positive exponents?
Tamiku [17]

Answer:

5^1

Step-by-step explanation:

\sqrt{5} =5^{\frac{1}{2} } (law of indices - fractional powers)

after converting all the numbers to this form:

\frac{5^{{\frac{2}{3} }  } *  5^{\frac{1}{2} } }{5^{\frac{1}{6} } } \\

combine using law of indices:

5^(2/3+1/2-1/6) = 5^1

I need some help please!
kvv77 [185]

Answer:

See below

Step-by-step explanation:

<u>Given</u><u> </u><u>:</u><u>-</u><u> </u>

  • y || z

<u>To </u><u>Prove</u><u> </u><u>:</u><u>-</u><u> </u>

  • m∠5 + m∠2 + m∠6 = 180°

<u>Proof</u><u> </u><u>:</u><u>-</u><u> </u>

Here we are required to prove that ,

\rm\implies m\angle 5 + m\angle 6 + m\angle 2 = 180^o

And here it's given that , y || z . Therefore ,

  1. ∠3 = ∠6 ( alternate interior angles )
  2. ∠1 = ∠5 ( alternate interior angles )

Now we know that the measure of a straight line is 180°. Therefore ,

\rm\implies m\angle 1 + m\angle 2 + m\angle 3 = 180^o \\\\\implies\boxed{\rm  m\angle 5 + m\angle 6 + m\angle 2 = 180^o}

  • From 1 and 2 .

Hence Proved !

1. Much has been made about the overall intelligence of criminal offenders in general, and violent offenders particular. There i
Tom [10]

Answer:

With regard to intelligence scores, at 95% confidence level, there is significant evidence to conclude that violent offenders are less intelligent than property offenders

Step-by-step explanation:

H_a: Violent offenders are less intelligent than property offenders

H_o: Violent offenders and property offenders do not differ significantly with regard to intelligence scores

Test statistic can be found using the formula

z=\frac{X-Y}{\sqrt{\frac{s(x)^2}{N(x)}+\frac{s(y)^2}{N(y)}}} where

  • X is the mean IQ score of property offenders (96)
  • Y is the mean IQ score of violent offenders (88)
  • s(x) is the sample standard deviation of property offenders (8.5)
  • s(y) is the sample standard deviation of violent offenders (7.5)
  • N(x) is the sample size for property offenders (225)
  • N(y) is the sample size for violent offenders (200)

then z=\frac{96-88}{\sqrt{\frac{8.5^2}{225}+\frac{7.5^2}{200}}} ≈10.3

One tail p-value of the test statistic is < 0.00001

Since  p-value<0.05 (significance level) we reject the null hypothesis.
