A credit card company charges 24.99% annually for its interest rate. There is a a 2450 balance.how much interest would be charge

BaLLatris [955]

A credit card company charges 24.99% annually for its interest rate

Total balance = 2450

we have to find the interest which would be charged in dollars

So to find the interest which would be charged in dollars we have to multiply total balance by the interest rate which is 24.99 and then divide it by hundred

so our interest comes = 2450*24.99/100 which comes out to be 612.255

Amanda [17]

Answer:

Total number of people in the line for the dunking machine is 8.

Step-by-step explanation:

Here, let us assume the number of people in the line for hoop shoot = 12

So, the number of people in the line for cakewalk

= One- Third of the number of people in line for Hoop Shoot

= $\frac{1}{3} \times 12 = 4$

Also, the number of people in the line for dunking machine

= 2 x ( The number of people in line for Cakewalk)

= 2 x 4 = 8

Hence, the total number of people in line for the dunking machine is 8.

You are testing the claim that the mean GPA of night students is different from the mean GPA of day students. You sample 30 nigh

kirill [66]

Answer:

Step-by-step explanation:

This is a test of 2 independent groups. The population standard deviations are not known. Let μ1 be the mean GPA of night students and μ2 be the mean GPA of day students.

The random variable is μ1 - μ2 = difference in the mean GPA of night students and the mean GPA of day students.

We would set up the hypothesis.

The null hypothesis is

H0 : μ1 = μ2 H0 : μ1 - μ2 = 0

The alternative hypothesis is

H1 : μ1 ≠ μ2 H1 : μ1 - μ2 ≠ 0

This is a two tailed test.

Since sample standard deviation is known, we would determine the test statistic by using the t test. The formula is

(x1 - x2)/√(s1²/n1 + s2²/n2)

From the information given,

μ1 = 2.35

μ2 = 2.58

s1 = 0.46

s2 = 0.47

n1 = 30

n2 = 25

t = (2.35 - 2.58)/√(0.46²/30 + 0.47²/25)

t = - 1.8246

The formula for determining the degree of freedom is

df = [s1²/n1 + s2²/n2]²/(1/n1 - 1)(s1²/n1)² + (1/n2 - 1)(s2²/n2)²

df = [0.46²/30 + 0.47²/25]²/[(1/30 - 1)(0.46²/30)² + (1/25 - 1)(0.47²/25)²] = 0.00025247091/0.00000496862

df = 51

We would determine the probability value from the t test calculator. It becomes

p value = 0.0746

Since alpha, 0.05 < than the p value, 0.0746, then we would fail to reject the null hypothesis.
