2.087 greater or less than 2.15

2 answers:

7 0

2.087 is less than 2.15 because after the 2 and the decimal there is a 0 in the first one, and 1 in the second one. 1 is obviously bigger than 0. Always go i order and compare the number one by one, that's how you know

Less than because 2.15 is a tenth greater.

nydimaria [60]

First, list all the given information:
*100 miles/week
*25 miles/gallon
*$4/gallon
*weekly expenditure reduced by $5

The easiest approach to use here is the dimensional analysis. Cancel out like units if they appear both in the numerator and denominator side. Solve first the original cost. The solution is as follows:

100 miles/week * 1 gal/25 miles * $4/gal = $16/week

The reduced cost would be:
16 - 5 = (New average miles/week) * 1 gal/25 miles * $4/gal
New average miles/week = 68.75 miles/week

Suppose that we want to investigate whether curfews correlate with differences in grades for students in middle school. We selec

Anton [14]

Answer:

Step-by-step explanation:

Hello!

Given the variables

X: Curfew of middle school students (Categorized Yes/No)

Y: Average grade of middle school students. (Categorized: A, B, C, and D)

The objective is to test if there is an association between both variables, you have to conduct a Chi-Square test of independence.

In the null hypothesis, you state that both variables are independent vs. the alternative hypothesis that the variables are dependent.

The hypotheses for this test are:

H₀: Pij= Pi. * P.j i= (1)Yes, (2)No; j= (1)A, (2)B, (3)C, (4)D

H₁: Te variables are not independent.

α: 0.05

$X^2= sum\frac{(O_{ij}-E_{ij})^2}{E_{ij}} ~~X_{(r-1)*(c-1)}$

Where

Oij is the observed frequency for the i-row and j-column

Eij is the expected frequency for the i-row and j-column

r= number of categories in the rows

c= number of categories in the columns

$X^2_{H_0}= 1.4796703$

p-value: 0.687

The p-value is greater than the significance level, so the decision is to not reject the null hypothesis. So using a 5% significance level, you can conclude that having a curfew and the average grades of middle schoolers are two independent variables.

The histogram below shows the estimated monthly salaries of company employees with different years of experience.

skad [1K]

From the Histogram displaying the the estimated monthly salaries of company employees with different years of experience, the graph might be misleading given that:
The scale on the y-axis overemphasizes the difference in salaries between different experience levels.

It might not be the case always that salary increment is proportional to experience, this might not fit all the cases.

navik [9.2K]

Answer:

45.5 yards.

Step-by-step explanation:

We are given that two players are located at the points A and B in the rectangular field.

It is given that,

Point A is located 50 yards from the west edge and 25 yards from the south edge.

Thus, point A is given by the co-ordinate (50,25).
