Answer: 3 and 4/5

Step-by-step explanation: To write an improper fraction as a mixed number, we divide the denominator into the numerator.

So in this problem, we divide 5 into 17.

5 divides into 19 three times.

3 x 5 is 15 and 19 - 15 is 14.

So 5 divides into 3 times with a remainder of 4.

In other words, we have 3 wholes and 4 out of 5.

We keep the same denominator.

So our mixed number is 3 and 4/5.

Graph Solution to System of Equations

One approach to solving systems of equations of two variables is the graph method.

Both equations are plotted in the same grid and we find the intersection point(s) of both graphs. Those are the feasible solutions.

The annual premium p as a function of the client's age a for two companies are given as:

Company A: p= 2a+24

Company B: p= 2.25a+13

The graphs of both functions are shown in the image below.

The red line indicates the formula for Company A and the blue line indicates the formula for Company B.

It can be seen that both lines intersect in the point with approximate coordinates of (44,112).

The age at which both companies charge the same premium is 44 years

Answer:

Step-by-step explanation:

Given:

$\dfrac{c^2-4}{c+3}\div \dfrac{c+2}{3(c^2-9)}$

Changing the division to multiplication by taking the reciprocal of the second fraction.

$\dfrac{c^2-4}{c+3}X \dfrac{3(c^2-9)}{c+2}$

The correct option is C

A sample of size 126 will be drawn from a population with mean 26 and standard deviation 3. Use the TI-84 calculator.

GenaCL600 [577]

Answer:

1. The probability that x will be more than 25 is 0.6305.

2. The 55th percentile is 26.38.

Step-by-step explanation:

Normal Probability Distribution

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

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

$Z = \frac{X - \mu}{\sigma}$

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.

Mean 26 and standard deviation 3.

This means that $\mu = 26, \sigma = 3$
