Imani bought books for college and paid 35% of the total cost. Her parents paid the remaining balance of $438.75. The total cost

Gnom [1K]

Answer:

$\$675$

Step-by-step explanation:

Remember that

$100\%-35\%=65\%=65/100=0.65$

Let

x ----> the total cost of the books

we know that

The total cost of the book multiplied by 0.65 must be equal to $438.75

The linear equation that represent this situation is

$0.65x=438.75$

solve for x

$x=438.75/0.65\\x=\$675$

Assume that the random variable X is normally distributed, with mean mu equals 100 and standard deviation sigma equals 20. Comp

TEA [102]

Answer: 0.2119

Step-by-step explanation:

We assume that the random variable X is normally distributed.

Given : Population mean : $\mu=100$

Standard deviation : $\sigma=20$

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

Then, z-score corresponds to 116

$z=\dfrac{116-100}{20}=0.8$

By using the standard normal distribution table for z , we have

$P(x>116)=P(z>0.8)=1-P(z\leq0.8)$

$=1-0.7881446\approx0.2119$

Hence, the required probability = 0.2119
