Answer:
$32.13
Step-by-step explanation:
Initial price = $36.00
Less 15 % = 0.15 × 36 = <u> -5.40
</u>
Sale price = $30.60
Plus 5 % = 0.05 × 30.60 = <u> 1.53
</u>
Amount paid = $32.13
The ratio up to forward is 2:5 (For every two feet the ramp goes up it also goes 5 feet forward).
<span>If this ratio remained constant and we went x feet up and 22.5 feet forward, then x:22.5=2:5,

</span><span>5x=2·22.5,

5x=45,
x=45÷5,
x=9.
Answer: 9 feet up

Answer:
1 ofc
Step-by-step explanation:
Think of it:
1% is pretty much ![\frac{1}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B100%7D)
so the equal to that is 1

I will do the hypothesis test.
The null hypothesis is: p <= 0.21
The alternative hypothesis is: p > 0.21
Since the confidence interval for this problem is 95%
The critical value for this is 1.960
So the alpha is .05, the p value is equal to 0.05/2 = 0.025
since it is a 2 tailed test. (letter b)
So p value = 0.025 < 0.5, therefore, reject null
hypothesis. More than 21% like the new soft drink.
