Answer:

I = $4204.8

Step-by-step explanation:

Given that,

Principal, P = $43,800

Interest rate = 4.8%

Rate = 2 years

We need to find the interest that is paid back. We know that, simple interest is given by :

[tex]I=\dfrac{PRT}{100}[/tex]

Put all the values,

[tex]I=\dfrac{43800\times 4.8\times 2}{100}\\\\=\$4204.8[/tex]

So, the required interest is equal to $4204.8 .

Answer:

D

Step-by-step explanation:

Let the number be n.  Then "a number divided by 22" would be n/22 (Answer D)

The number divided by 22 can be written as x / 22, so option D is correct.

It is a fundamental operation in mathematics where you divide a number into smaller parts.

Given:

A number divided by 22,

Here, the divisor = 22

Assume the number is x

Then, dividend = x

Thus, expression can be written as,

dividend/divisor = x / 22

Answer:

B

Step-by-step explanation:

elimination

4x - y = 8

6x + y = 2

--------------- +

10x = 10

x = 1

since x = 1, we can subtitute x to one of those equations

4x - y = 8

4(1) - y = 8

4 - 8 = y

y = 4 - 8

y = -4

x,y = 1,-4

Answer:

B is correct

Step-by-step explanation:

you add the two equations together. So 4x + 6x  equals what? 10x. we know that y and -y cancel each other out. and then we all know that 8+2 is 10. now we have 10x=10 so x=1. We replace x for one and then we have 4 - y =8 so y has to equal -4 and there you have your answer, b

Step-by-step explanation:

Sample scores : 105, 98, 101, 110, 96, 103, 104, 101, 98, 105, 112, 95, 105, 100, 108

Sample mean, xbar = 102.73

Standard deviation, s = 4.98

H0: μ = 98ttt

H1 : μ ≠ 98

Test statistic :

(xbar - μ) ÷ s/sqrt(n)

(102.73 - 98) ÷ 4.98 / sqrt(15)

t = 3.655

Pvalue from t score = 0.002599

When. Pvalue < α ; We reject the Null

Step-by-step explanation:

-8×5 = -40

-40/4 = -10

-10×6 = -60

Answer: D) 2

Step-by-step explanation:

The standard deviation of the difference between the means of the two populations is given by:-

[tex]S.E.=\sqrt{\dfrac{\sigma^2_1}{n_1}+\dfrac{\sigma^2_2}{n_2}}}[/tex]

where [tex]n_1[/tex]= sample size of population 1

[tex]n_2[/tex]= sample size of population 2

[tex]\sigma^2_1[/tex]= variance of population 1

[tex]\sigma^2_2[/tex]= variance of population 2

As per given,

[tex]S.E.=\sqrt{\dfrac{112.5}{45}+\dfrac{54}{36}}}\\\\=\sqrt{4}\\=2[/tex]

Hence, the correct option is D) 2.

Step-by-step explanation:

48/112 = 0.4285

convert and round it

0.4285 = %42.9

The percent of the 7th grade students were in favor of wearing school uniforms is 42.9%.

From the given table,

7th grade students who are in favor of wearing uniform = 48

Total 7th graders = 112

So, the percent of the 7th grade students were in favor of wearing school uniforms

= 48 / 112 x 100

= 12 / 23 x 100

= 42.85%

Answer:

The desired z-score is 2.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 p-value, we get the probability that the value of the measure is greater than X.

n(12,2.5)

This means that [tex]\mu = 12, \sigma = 2.5[/tex]

z score when x =17

This is Z when X = 17. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{17 - 12}{2.5}[/tex]

[tex]Z = 2[/tex]

The desired z-score is 2.
