Amount of instant tea = 24 ounces

Amount of green tea = 12 ounces

Caffeine in instant tea = 40 mg / 8 fl. oz. = 5 mg/fl.oz.

Caffeine in green tea = 25 mg /8 fl. oz. = 3.125 mg/fl.oz.

Caffeine in 24 ounces of instant tea = 5* 24 = 120 mg

Caffeine in 12 ounces of green tea = 3.125 * 12 = 37.5 mg

Total amount of the mixture = 24 + 12 =36 ounces

Total amount of caffeine in the mixture = 120 + 37.5 = 157.5 mg

Caffeine per ounce in the final mixture = 157.5 / 36 = 4.375 mg/ fl.oz

Fruit juice comes in two types of containers. The first is a rectangular prism that is 9 inches tall and has a rectangular base
My name is Ann [436]

The volume of a rectangular prism:

V_p=Bh\\\\B=wl\\\\w=2\ in;\ l=3\ in;\ h=9\ in

substitute

V_p=2\cdot3\cdot9=54\ in^3

The volume of a cylinder:

V_c=\pi r^2h\\\\r=1.5\ in;\ h=8\ in

substitute:

V_c=\pi\cdot(1.5)^2\cdot8=\pi\cdot2.25\cdot8=18\pi\ in^3\approx18\cdot3.14=56.52\ in^3

Answer: C. The cylinder has the greater volume.

The margin of error of a given statistic is an amount that is allowed for in case of miscalculation or change of circumstances.

It is usually the radius or half of the width of the confidence interval of that statistic.

Given that a<span> survey of the students in Lance’s school found that 58% of the respondents want the school year lengthened, while 42% think it should remain the same. The margin of error of the survey is ±10%.

This means that 58% </span><span>± 10% of the </span>respondents want the school year lengthened, while 42% <span><span>± 10% think it should remain the same.</span>

Thus, from 48% to 68% </span><span><span>of the respondents want the school year lengthened, while from 32% to 52% <span>think it should remain the same.</span> </span>

Therefore, according to the survey data, at least 32% of students want the duration of the school year to remain unchanged, and at least 48% want the school year to be lengthened.</span>
