Answer:

How do you turn 28/15 into a mixed number

Bond [772]

$\frac{28}{15} = \frac{15 + 13}{15} = \frac{15}{15} + \frac{13}{15} = 1 + \frac{13}{15} = 1 \frac{13}{15}$

Assuming that workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year, find the probabi

lord [1]

Answer:

The probability is $P(\$20,000 < X < \$35,000) = 0.6$

Step-by-step explanation:

From the question we are told that

Workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year

Generally the probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000 is mathematically represented as

$P(\$20,000 < X \$35,000) = \frac{ 35000 - 20000}{ 40000 - 150000}$

=> $P(\$20,000 < X < \$35,000) = 0.6$

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 100 and a standard deviation sigma equa

aleksley [76]

Answer: 0.5467

Step-by-step explanation:

We assume that the test scores for adults are normally distributed with

Mean : $\mu=100$

Standard deviation : $\sigma=20$

Sample size : = 50

Let x be the random variable that represents the IQ test scores for adults.

Z-score : $z=\dfrac{x-\mu}{\sigma}$

For x =85

$z=\dfrac{85-100}{20}\approx-0.75$

For x =115

$z=\dfrac{115-100}{20}\approx0.75$

By using standard normal distribution table , the probability the mean of the sample is between 95 and 105 :-

$P(85$

Hence, the probability that a randomly selected adult has an IQ between 85 and 115 =0.5467
