Sati [7]

Answer:

Step-by-step explanation:

Amount paid by Joanne before promotion = 74 + 59 + 69 = $ 202

a) Amount saved if she switches to "3 for 129 plan" = 202 - 129 = $ 73

Percentage of saving = $\frac{73}{202}*100$ = 36.13 = 36%

b) Amount saved after the first year = 202 - 139 = $ 63

Percentage of saving = $\frac{63}{202}*100$ = 31.18 = 31%

Suppose that 1 month before the election a random sample of 500 registered voters are surveyed. From this sample 270 indicate th

Aleonysh [2.5K]

Answer:

[ 0.4964, 0.5836 ]

Step-by-step explanation:

Data provided in the question:

Total sample size = 500

person voting for smith = 270

thus,

P( person voting for smith ), p = $\frac{270}{500}$ = 0.54

Confidence level = 95%

now,

standard error, SE = $\sqrt{\frac{p(1-p)}{n}$

SE = $\sqrt{\frac{0.54(1-0.54)}{500}$

SE = 0.0223

now,

Confidence interval = p ± ( z × SE )

here,

z value for 95% confidence interval is 1.96

Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]

= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]

= [ 0.4964, 0.5836 ]

Last weekend , 5% of tickets sold at sea world were discount tickets. If seaworld sold 60 tickets in all , how many discount tic

Dafna1 [17]

So lets take a look at what we know:

5% of the tickets were discount
100% of the tickets is equal to 60 tickets

From this information we can create the proportion:

$\frac{x}{5} = \frac{60}{100}$ .

Cross Multiply to get $100x=300$

Divide 100 on each side to get $x=3$ .

Three discount tickets were sold.

S+2t=6. 3s-2t=2<br> Using elimination

Ludmilka [50]

For the first one, I will solve for t.
s + 2t = 6, first we isolate the t variable,
2t = -s + 6, divide both sides by 2,
t = -s/2 + 3, < There's your answer for 1!

Here's the second one,
3s - 2t = 2, subtract 3s from both sides,
-2t = 2 - 3s, divide both sides by -2,
t = -1 + 3s/2 < There's your second answer!
