Troyanec [42]

Answer:

40%.

Step-by-step explanation:

We have been given that the owners of Expo Company John Smith and Susan Jones invested $240,000 and $160,000 into the business respectively. We are asked to find the percentage of business owned by Susan.

Let us figure out total money invested in business by adding the money invested by John Smith and Susan Jones.

$\text{Total money invested in business}=\$240,000+\$160,000$

$\text{Total money invested in business}=\$400,000$

Now we will find $160,000 is what percent of $400,000.

$\text{Percentage of business Susan own}=\frac{160,000}{400,000}\times 100$

$\text{Percentage of business Susan own}=0.4\times 100$

$\text{Percentage of business Susan own}=40$

Therefore, Susan owns 40% of the business.

Liliana used 444 dark power crystals to raise 141414 zombie soldiers. She wants to know how many zombie soldiers (z)(z)left pare

Mariulka [41]

Question is bit incorrect, Correct question is given below.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) she can raise with 10 dark power crystals. How many zombie soldiers can Liliana raise with 10 power crystals?

Answer:

Liliana can raise 35 zombie soldiers.

Step-by-step explanation:

Let the number of zombie soldiers raised by 10 dark power crystals be 'z'.

Zombie raised by 4 power crystals = 14

Since the number of zombie and power crystals are in direct proportion.

Therefore, we get

$\frac{z}{10}=\frac{14}{4}$

Multiply 10 on both the sides, we get

$z=\frac{14}{4}\times 10 = 35$

Hence, Liliana can raise 35 zombie soldiers.

"How much do students pay, on average, for textbooks during the first semester in college? From a random sample of 400 students

dezoksy [38]

Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

Step-by-step explanation:

Since we have given that

Sample size = 400

Mean = $357.75

Standard deviation = $37.89

At 95% confidence level, z = 1.96

We first find the margin of error.

Margin of error is given by

$z\times \dfrac{\sigma}{\sqrt{n}}\\\\=1.96\times \dfrac{37.89}{\sqrt{400}}\\\\=3.71$

95% confidence interval would be

$\bar{x}\pm \text{margin of error}\\\\=357.75\pm 3.71\\\\=(357.75-3.71,357.75+3.71)\\\\=(354.04,361.46)$

Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
