Approximate the solution to the system of equations.

Mathematics
1 answer:
Ann [662]3 years ago
8 0

Answer:

a) at x=0.5  y=2  and at x=1  y=2 this similarity in values shows that the solution for x is between 0.5 and 1

c) The x  solution will be between  x=0.0 and x=0.7 .

There is a similarity in values of y at x=0.6, y=2.4 and at x=0.7 , y=2.4

d) For x= (0.6+0.7)/2 = 1.3/2 =0.65

   For y= (2.4+2.3)/2 =4.7/2=2.35

  Approximate solution is (0.65, 2.35)

In school B, the angle representing the sector of students that like tigers is 90 degrees while in school A, the angle representing the sector of students that like tigers is larger than 90 degrees. this is determined by perusing the images visually.

Step-by-step explanation:

Please find the complete question in the attached image

Pie chart is a graph used to represent numeric information. the sum of angles in a pie chart equals 360 degrees. the pie chart is usually separated into sectors to represent numeric information

the angle representing the students that like tigers in school A = 0.5 x (360 - 60) = 150 degree

For a random sample of Harvard University psychology majors, the responses on political ideology had a mean of 3.18 and standard
Nutka1998 [239]

Answer:

From the test give in the question it is obvious that  there is enough evidence to show that population mean varies for vegetarian and non-vegetarian

The P-value helps affirm the null hypothesis claims,The P-value attains  values relatively as large as that which exists in the sample given,if the null hypothesis is right

Step-by-step explanation:

From the question we are told that

Sample mean \=x_1=3.18

Standard deviation \delta_! =1.72

Sample size n_1 =51

Sample mean \=x_2=2.22

Standard deviation \delta_2 =0.67

Sample size n_2=20

Generally this is a two tailed test

therefore

   Null hypothesis  = h_0 :P_v_e_g= P_n_o_n_v_e_g

  Alternative hypothesis H_a : P_v_e_g \neq  P_n_o_n_v_e_g

From the test give in the question it is obvious that  there is enough evidence to show that population mean varies for vegetarian and non-vegetarian

The P-value helps affirm the null hypothesis claims,The P-value attains  values relatively as large as that which exists in the sample given,if the null hypothesis is right
