Principle 1600, rate 6 ,time 2.5 years find CI​

Mathematics
1 answer:
shutvik [7]3 years ago
5 0

Answer:

C.I = $251.2

Step-by-step explanation:

P = Principal amount = 1600

r = rate of annual interest = 6%

n = period / no. of years = 2.5 years

C.I = (P* (1+r^n))-P

C.I = (1600*(1+0.06)^2.5))-1600

C.I = (1600*(1.06^2.5))-1600

C.I = (1600*1.157)-1600

C.I = 1851.2-1600

C.I = 251.2

At George Washington High School, 119 students walk to school. If this number is 35% of school enrollment, then how many student
nignag [31]

Answer: 340 students

Step-by-step explanation:

The number of students walking to school is 119 and this is 35% of the total number of students.

Assume the total number is denoted by "x".

That would mean that the following formula captures the situation:

119 = 35% * x

119 = 0.35x

x = 119/ 0.35

= 340 students

The weight of a small Starbucks coffee is a normally distributed random variable with a mean of 330 grams and a standard deviati
just olya [345]

Answer:

Weights of at least 340.1 are in the highest 20%.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 330, \sigma = 12

a. Highest 20 percent

At least X

100-20 = 80

So X is the 80th percentile, which is X when Z has a pvalue of 0.8. So X when Z = 0.842.

Z = \frac{X - \mu}{\sigma}

0.842 = \frac{X - 330}{12}

X - 330 = 12*0.842

X = 340.1

Weights of at least 340.1 are in the highest 20%.
