Well we know that all the sides are congruent so you can use SSS

There are two sides and one angle that is congruent therefore SAS

You have pairs of legs that are congruent so  LL

Lastly we know that JK and QR are congruent so you get HA

Hope this helps :)

Naomi deposited money into savings account that is compunded quarterly at an interest rate of 6%. She thinks this quarterly rate
FromTheMoon [43]

Answer:

No, because 1.25% times 3 is 3.75% which is less than 6%

Step-by-step explanation:

Quarterly is every 3 months

6% interest is 1.06, 6 cents on the dollar

Monthly interest rate is 1.25% so 1.25 × 3 is 3.75

So, 1.25% times 3 is 3.75% which is 2.25% less than 6%

Hope this helps!

Have a great day!

A survey of households in a small town showed that in 850 of 1,200 sampled households, at least one member attended a town meeti
Iteru [2.4K]

Answer:

Hence the confidence interval is ( 0.6745, 0.7422).

Step-by-step explanation:

Now the given are  

Sample size = n = 1200  

x = 850  

Sample proportion is  

\hat{p}=\frac{x}{n}=\frac{850}{1200}=0.7083  

We have to construct 99% confidence interval for the population proportion.  

Formula Used:  

(\hat{p}-E , \hat{p}+E)  

Here E is a margin of error.  

E =Zc\times\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}  

Zc = 2.58  

E =2.58\times\sqrt{\frac{0.7083*(1-0.7083)}{1200}}\\\\E=2.58\times\sqrt{0.000172}=0.0339  

So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)

                                            = ( 0.6745 , 0.7422).

Cherie bought 2 cupcakes and got $12.50 back.Sonya bought 4 cupcakes and got $5.00 back.If they each paid with the same amount o
blondinia [14]

Answer:

The cost of 1 cupcake  = $3.75.

Step-by-step explanation:

Let the cost of one cupcake = $ x.00

Now, the money spent by Cherie on 2 cupcakes = 2 ($x.00) = $2x

Also, the money spent by Sonya on 4 cupcakes = 4 ($x.00)  = $4x

Now, according to the question:

$2x  + $12.50  = $4x  + $5.00

or, 2x + 12.50 = 4x + 5

⇒ 4x - 2x = 12.50 - 5

or, 2x = 7.50

or, x  = 7.50/2 = 3.75

or, x = $3.75

Hence, the cost of 1 cupcake  = $3.75.
