Zina [12379]

Answer: y = 2/5 --> y = 0.4

Step-by-step explanation:

The equation 5y = 2 represents a horizontal line at y = 2/5.

This means that the y-coordinate holds the value of 2/5 = 0.4 for any x-coordinate.

The average height of females in the freshman class of a certain college has historically been 162.5 centimeters with a standard
Svet_ta [12734]
To determine if there is evidence suggesting a change in average height, we can conduct a right-tailed test and formulate both null and alternative hypotheses.

H₀ (null hypothesis): μ = 162.5
H₁ (alternative hypothesis): μ > 162.5

With two samples to analyze, we can calculate the z-score using the formula provided below.

Z = \frac{(\chi - \mu)}{ \sigma / \sqrt{n}}

In this formula, Z symbolizes the z-score, Χ denotes the new sample mean, μ indicates the theoretical average, δ represents the standard deviation, and n signifies the sample size. Based on the gathered values, 

Z = \frac{(165.2 - 162.5)}{6.9 / \sqrt{50}}
Z \approx 2.77

Assuming a significance level of α = 0.05. With a z-score of 2.77, we can reference the z-table to ascertain the p-value. This yields P(Z > 2.77) =.0028. Since our p-value is below α, we reject the null hypothesis, indicating that the average height of female freshman students has indeed shifted.

The tiles that Bruce used were each of a square foot in the area. The table shows the area covered by Felicia’s tiles in terms o
zzz [12365]

Response:

Step-by-step explanation:

We need to form an equation that illustrates the area that Felicia has covered, denoted as y, in relation to the number of tiles she utilized, represented by x.

Let x= Number of tiles

y=Area occupied by Felicia's tiles

x_1=9, x_2=18, x_3=27

y_1=1, y_2=2,y_3=3

\frac{x_1}{y_1}=\frac{9}{1}=9

\frac{x_2}{y_2}=\frac{18}{2}=9

\frac{x_3}{y_3}=\frac{27}{3}=9

The relationship between x and y is constant. Hence, it follows a direct proportion.

The equation for direct proportion is shown as

\frac{x}{y}=k

Where

k=The value of the ratio of x and y

x and y are variable factors

Here, we have k=9

Substituting the known values into the equation

leads us to

\frac{x}{y}=9

x=9y

y=\frac{1}{9}x

This represents the necessary equation depicting the area Felicia covered, y, in terms of the number of tiles utilized, x.

The newly elected president needs to decide the remaining 8 spots available in the cabinet he/she is appointing. If there are 14
AnnZ [12381]
The cabinet appointments can occur in 121,080,960 different configurations. This is a permutations problem since the order of selection matters; swapping candidates results in a new arrangement. This leads us to utilize the permutation formula. Given there are 14 viable candidates for 8 spots, we need to compute the permutations of 8 from a set of 14, concluding that the cabinet can indeed be arranged in 121,080,960 distinct ways.
